  • Compound Exhaust Valve

    Compound Exhaust Valve

    Compound exhaust valve is a kind of floating ball exhaust valve made by Bernoulli's theory, which can keep fully open under the air flow. When the solid water column rises, the floating ball can float immediately and close the exhaust port tightly. Compound exhaust valve adopts a specific diameter of floating ball, so that the aerodynamic force generated by it can keep the floating ball open when the air flows through, and the buoyancy generated when the solid water column rises can make it float again. With a cone at an appropriate angle at the inlet, the exhaust port will not be blocked no matter how high the air pressure or the air velocity.

  • What is the difference between butterfly valve and gate valve?

    Butterfly valve and gate valve are common valve types, widely used in industrial and civil fields. Although they are both valves used to control the flow of media, they differ in structure, use occasions and control methods. These differences will be described in detail below.

  • Features of Soft Seal Butterfly Valve

    With the increase of the reverse medium pressure, when the unit positive pressure between the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat is less than the medium pressure, the deformation stored in the spring of the adjusting ring after loading can compensate the soft-sealed butterfly valve plate and the soft-sealed butterfly valve seat. The tight pressure on the sealing surface of the sealing butterfly valve seat plays an automatic compensation role.

  • Are ball valves and gate valves the same?

    The valve core of the ball valve is a sphere. Due to its fixed ball structure, the valve ball is fixed under high pressure, especially when it is closed. Its upper stem and lower pivot decompose part of the pressure from the medium, so The valve ball does not deflect downstream, so the pressure on the downstream valve seat is relatively small.

  • What Kind of Valve Material Should be Selected for Corrosive Medium

    Corrosion is one of the most troublesome hazards of chemical equipment. Slight carelessness may damage the equipment, or cause accidents or even disasters. According to the relevant statistics, about 60% of the damage of chemical equipment is caused by corrosion, so the selection of chemical valves should be scientific.
