Open spherical gate valve, open spherical gate valve, open spherical gate valve, gate valve opening and closing parts is the gate, the movement direction of the gate is perpendicular to the fluid direction, gate valve can only be fully open and fully closed, not suitable for adjustment and throttling. The gate has two sealing surfaces. The two sealing surfaces of the commonly used wedge gate valve form a wedge. The wedge angle varies with the valve parameters, usually 5o. Wedge gate valve gate can be made into a whole, called a rigid gate; can also be made to produce micro deformation of the gate, in order to improve the process, make up for the sealing surface angle in the process of deviation, this gate is called elastic gate.
The type of gate valve, according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve can be divided into: single gate pole type, double gate plate type and elastic gate type; parallel gate valve can be divided into single gate type and double gate plate type. According to the thread position of the valve stem, it can be divided into two kinds of open rod gate valve and dark rod gate valve. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the sealing surface of the gate pressure to the other side of the valve seat to ensure the sealing surface of the seal, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on the external force to press the gate to the valve seat to ensure the sealing surface. The utility model relates to an open spherical gate valve, which comprises a valve body,

The working principle of hydraulic balance valve
Hydraulic valve manufacturer# Hydraulic balance valve is a device used to control the speed of hydraulic cylinder movement in hydraulic system. Its working principle is as follows: The hydraulic balance valve consists of a movable spool and a constant pressure spring. There are two holes on the spool, which are connected with the two chambers of the hydraulic cylinder. When the hydraulic system applies pressure, the pressure will act on a hole in the spool, causing the spool to move in the opposite direction.

Common use and performance of imported valves to explain
Valves have different requirements according to their types and uses, mainly sealing, strength, regulation, circulation, opening and closing performance. In the process of selecting the valve, in addition to considering the basic parameters and performance, but also consider the performance of the valve. So what are the different valve performance characteristics?
