Electric Gate Valve Cast Steel Plug-in Valve
1. Introduction
Knife gate valve is a kind of valve gate and seat always close contact sealing valve, its principle is the gate is open on the size of a pass size of the round mouth, through the gate opening and closing of the gate makes the gate on the round mouth with the pass diameter to do completely detached and coincide with the action. The advantage of this valve is that the valve body diameter without grooves, the media will not be blocked blockage, and has a full diameter circulation characteristics, the sealing structure can be divided into soft seal, hard seal structure. Penetrating knife gate valve is characterized by precision construction, good workmanship, compact structure, etc. The sealing seat is designed as a movable structure, with anti-wear and automatic compensation function, thus the life is longer.
In the closing and opening process, the valve seat and the gate have been close to the movement, so that the valve opening and closing force is stable, and has the characteristics of cutting off the medium and so on.
2. Characteristic
Electric plug valve in the use of precautions and its characteristics: plug valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the plug valve can only be used for full open and full closed, can not be used for regulation and throttling. Gate has two sealing surfaces, the most commonly used mode of gate valve two sealing surfaces to form a wedge, wedge angle with the valve parameters vary, usually 50, wedge-type gate valve gate can be made into a whole, called the rigid gate; can also be made to produce a small amount of deformation of the gate, in order to improve its craftsmanship, to make up for the angle of the sealing surface of the bias in the machining process, this gate is called the resilient gate gate gate valve closure, the sealing surface can only rely on the medium pressure, the sealing surface can only rely on the pressure of the fluid, the sealing surface can only be closed, not for regulating and throttling. Sealing surface can only rely on media pressure to seal, that is, relying on media pressure will be the sealing surface of the gate to the other side of the valve seat to ensure that the sealing surface of the seal, this is the self-sealing. Most of the plug valve is used to force sealing, that is, when the valve is closed, to rely on external forces to force the gate to the valve seat to ensure that the sealing surface of the sealing. Plug valve sealing structure can be divided into soft seal, hard seal structure.
