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 main technical performance of the copper valve
The strength performance of the copper valve refers to the ability of the copper valve to withstand the pressure of the medium. The copper valve is a mechanical product that bears internal pressure, so it must have sufficient strength and rigidity to ensure long-term use without cracking or deformation.
