The aro motor gasket is usually metal or plastic. High quality bolted connections require hardened steel washers to prevent preload loss due to Brinell hardness after torque application. Washers are also important to prevent galvanic corrosion, especially by insulating steel screws from aluminum surfaces. They can also be used for rotary applications such as bearings. Thrust washers can be used when rolling bearin

The exhaust muffler is manufactured from aluminized or stainless steel sheet. Usually the muffler consists of a resonance chamber, an expansion chamber and a set of porous tubes. Some are also filled with heat-resistant sound-absorbing material in the muffler, and the sound-absorbing material is mostly glass fiber or asbestos. The exhaust gas flows into the expansion chamber and the resonance chamber through the poro

The function of the exhaust muffler is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the pulsation of the exhaust pressure. We provide exhaust muffler products, if you are interested, please contact us for more information. The exhaust pressure of the engine is about 0.3~0.5MPa, and the temperature is about 500~700℃, which indicates that the exhaust gas has a certain amount

Sandpiper Seat Aluminum can be used for: 1. Connect the inlet and outlet pipes of the valve; 2. The valve chamber is formed to complete the guiding of the fluid in the valve; 3. Fixed valve operating mechanism, 4. Guide the directional movement of the valve flap; 5. Withstand the pressure of the fluid in the valve. The valve seat and the sealing ring are an elastic rubber sealing ring acting in the axial dire

The detachable surface parts in the valve are used to support the fully closed position of the valve core and form a sealing pair. Generally, the seat diameter is the maximum flow diameter of the valve. For example, the seat material of butterfly valve is very wide, all kinds of rubber, plastic and metal materials can be used as valve seat material. Use elastic sealing material and small actuator thrust to obtain

The role of the Wilden Air Valve is to remove the accumulated air in the line. Wilden Air Valve is a special valve used to prevent negative pressure in the pipe caused by the decompression wave in the transient process. It is usually installed at a high point where the dynamic water pressure is low when the pipeline is in normal operation, and the liquid column separation may occur during the transient flow process.

During the starting process of the water pump of Wilden Air Valve, when the valve body is not filled with water, the float ball in the valve body falls due to its own weight, and the air holes are all open. With the rise of the pump starting working head, the pipeline is filled with water, and the air can automatically remove the air in the pipeline. When the valve body starts to fill with water, the floating ball fl
