Introduction and subsequent use treatment of double gate valve
2021/06/24
The lower end of the valve stem of the double gate valve is integrated with the wedge-shaped cone through the screw and pin shaft. The trapezoidal thread on the top is matched with the stem nut. The rotation of the stem nut is carried out by a manual wheel, wheel, bevel gear, electric or pneumatic device. The valve disc is composed of the upper and lower parts of the finite ring and the wedge regulating valve, respectively, it cannot be raised or lowered by the cone, it can only be translated or rotated by the wedge cone in a horizontally long space.
The lower end of the valve stem is integrated with the wedge-shaped cone through screws and pins, and the upper trapezoidal thread is matched with the valve stem nut. The rotation of the valve stem nut is driven by a hand wheel, bevel gear, electric or pneumatic. terminal.
There is a crawler pin in the center of the valve stem. The two ends of the pin are equipped with rollers. The rollers roll in the guide groove of the bracket. The movement track of the valve stem is the guide groove. Depending on the processing conditions, the double gate valve has parts that need to be polished, and the surface needs to be free of processing burrs.

The Essential Guide to Water Hammer Arresters: Understanding Their Role in Industrial Valve Systems
Water hammer arresters play a vital role in the realm of industrial equipment and components, specifically within valve systems. These devices are designed to mitigate the effects of water hammer—a phenomenon that occurs when a fluid in motion suddenly stops or changes direction, resulting in pressure surges or shock waves. This situation can lead to severe problems such as damaged pipes, noisy pl

Understanding Water Hammer Arresters: Essential Components for Industrial Valve Systems
Water hammer, a phenomenon caused by sudden changes in fluid flow, can lead to significant pressure shockwaves within piping systems. This not only generates disruptive noise but also poses a risk to the integrity of your industrial equipment. Enter the water hammer arrester—a vital device designed to absorb these shockwaves, ensuring smoother operation and reducing the risk of damage to your valv
