Piston Pump
01In a small piston pump, the bowl plays a key role in sealing. It is installed around the plunger, when the plunger reciprocates in the pump cylinder, the bowl can effectively prevent the working medium (such as oil, water, etc.) from leaking out of the gap between the plunger and the pump cylinder, to ensure the efficiency of the pump and pressure stability. For example, in some small fuel piston pumps, the good sealing performance of the bowl ensures that the fuel can be accurately transported under high pressure to meet the fuel supply needs of the engine. -
Diaphragm Pumps
02In small diaphragm pumps, the bowl is usually used as part of the diaphragm or in conjunction with the diaphragm. Diaphragm pumps through the diaphragm reciprocating movement to achieve the medium suction and discharge, the bowl is used to seal the diaphragm and the pump body between the connection parts, to prevent media leakage. For example, in some small diaphragm pumps used to transport chemical reagents, the chemical resistance of the bowl can ensure that in the transport of corrosive reagents, the pump sealing is good, to avoid leakage of reagents on the surrounding environment and equipment damage. -
Hydraulic Valves
03In the hydraulic valves of small hydraulic systems, leather bowls can be used for sealing between the valve spool and the valve sleeve. When the hydraulic valve controls the flow direction and flow rate of hydraulic oil, the leather bowl can prevent the hydraulic oil from leaking in the gap between the spool and the valve sleeve, ensuring accurate and reliable pressure control of the hydraulic system. For example, in small hydraulic directional valves, the sealing performance of the bowl ensures that the hydraulic fluid can flow in a predetermined direction to achieve the correct action of the actuating elements (e.g., hydraulic cylinders, hydraulic motors, etc.). In some small hydraulic systems, the bowl is used for the sealing and piston components of the hydraulic pump. It can ensure the normal flow of hydraulic oil in the pump and pressure formation, to prevent oil leakage, to ensure the stable operation of the hydraulic system, for small mechanical equipment such as small hydraulic jacks, hydraulic tools, etc. to provide power. -
Pneumatic valves
04For small pneumatic valves, leather bowls are commonly used for sealing between the valve stem and the valve body. When the pneumatic valve through the compressed air to control the gas on and off and flow, the skin bowl can prevent the compressed air leakage, to ensure that the valve action is sensitive and stable. For example, in some small pneumatic control valves, the sealing effect of the skin bowl makes the control valve can accurately adjust the gas flow according to the control signal to meet the working requirements of the pneumatic system. -
Metering pumps
05Small metering pumps are often used for precise delivery of a small amount of liquid occasions, such as chemical experiments, pharmaceutical industry in the delivery of small doses of pharmaceuticals, as well as food and beverage industry in the precise addition of additives, sanitary bath flow control, and so on. Leather bowl in the metering pump to play a role in accurately controlling the flow, through its cooperation with the pump cavity, can accurately inhale and discharge a certain amount of liquid to ensure the accuracy of measurement.Our international famous brand bathroom customers commonly used, sealing anti-leakage, cushioning shock absorption, regulating the flow, can adapt to some of the grease and daily wear and tear in the bathroom environment; in some cases, the degree of deformation of the leather bowl can affect the flow of fluids. -
Toilet
06Used in the inlet and drain valves of a toilet. The leather bowl in the inlet valve controls the inflow of water into the tank and ensures that the water stops flowing in when it reaches the set level; the leather bowl in the drain valve opens when flushing, allowing the water in the tank to drain quickly, and closes tightly at the end of the flush to prevent leaks.Faucet
In some faucet valve core parts, the leather bowl plays a sealing role to prevent water leakage from the valve core, to ensure that the faucet can flexibly control the water flow switch and size. -
Shower head
07The internal structure of some shower heads will also be used in the bowl, used to seal the nozzle and water supply pipe connections, as well as some of the nozzle to control the direction of the water flow and size of the internal components, to ensure that the shower head can be a normal spray of water, and will not appear leakage phenomenon.In the pump valve work, the bowl can play a certain buffer role, reduce the collision and friction between the components, reduce noise, but also to extend the service life of the pump valve and related parts. It can effectively prevent the leakage of water or other liquids in the bathroom equipment, avoid water waste and equipment damage, and keep the bathroom space dry and clean. -
Pulse valve
08In the pulse valve of the smart toilet, the rubber valve and rubber diaphragm play a key role and are usually made of EPDM (EPDM) or silicone. EPDM is a kind of synthetic rubber with excellent performance and good water resistance, and as the smart toilet is in contact with water for a long time, EPDM can ensure that the valve and diaphragm will not be damaged in the humid environment. It has excellent weather resistance and can adapt to different seasons and changes in ambient temperature. At the same time, it is also chemically resistant to various chemicals that may be contained in the water, prolonging its service life. Silicone material, on the other hand, is known for its excellent heat and cold resistance. During the use of the smart toilet, the water temperature may change considerably, and silicone can maintain stable performance under different temperature conditions. Moreover, silicone has excellent elasticity, and in the process of frequent opening and closing of the pulse valve, it relies on its own elastic deformation to accurately control the flow of water. Rubber valve piece and rubber diaphragm piece by virtue of its own elasticity, in the work of the pulse valve, as a precision switch, to achieve the opening and closing action of the valve. When the pulse valve receives the signal, the valve piece and diaphragm piece deform to open the water flow channel; after the end of the signal, they return to their original state and isolate the water flow, so as to ensure the normal flushing function of the smart toilet. -
Spray Pump
09In a small spray pump, the leather bowl is an important part to realise the liquid spray function. It is through the compression and release to promote the liquid through the nozzle to form a spray, commonly used in the agricultural field of small sprayer for crop pest control and foliar fertiliser; in the beauty field, some small spray beauty instrument also uses the leather bowl spray pump, make-up, serum, and other liquids atomised for easy absorption by the skin. -
Fuel Pump
10In the fuel system of some small engines, such as motorbikes, small generators, lawnmowers, etc., small leather bowls are used for fuel pumps. Its role is to suck fuel out of the tank and deliver it to the engine's carburettor or injector nozzle to provide fuel for the engine. The bowl needs to have good oil resistance and sealing to ensure proper fuel supply and stable engine operation.Diverter valve is a device used to control the distribution of water flow, usually used to distribute one way inlet water to multiple outlet channels according to different needs, in order to achieve the water supply control of different water equipment or areas. Diverter valves generally consist of a valve body, spool, stem, handle or knob, and seals. The valve body has a water inlet and a number of outlets, the valve spool through the valve stem and the handle or knob is connected, by rotating the handle or knob can be driven to rotate the spool, so as to control the distribution of water flow. By rotating the handle or knob, the spool rotates in the valve body, changing the cross-sectional area of the channel between the spool and the valve body, thus adjusting the size of the water flow at each outlet. -
11When the spool is in a different position, the opening of different outlets is different, to achieve the distribution of water flow. Some diverter valves may also have a quantitative distribution function, through the precise design of the spool structure and rotation angle, to achieve a fixed flow distribution for each outlet. In the family, commonly used in the bathroom, kitchen and other water appliances share a common water source, such as the hot water heater hot water distribution to the washbasin, shower nozzle, bathtub and other different water equipment; in the industrial field, can be used in the cooling system, the cooling water will be distributed to the cooling of different equipment or components; in the agricultural irrigation, can be distributed to the main water pipeline water to the different irrigation areas or sprinkler heads, to achieve precise In agricultural irrigation, it can distribute water from the main pipe to different irrigation areas or sprinkler heads to achieve precise irrigation. -
