Manual Square Knife Gate Valve Manual Pinch Valves
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
Manual Plug Valve is also known as manual gate valve and manual screw plug valve,.
1, manual plug valve is often used with the discharge device or silo supporting, manual screw gate valve with flange connection is easy to install, inlet and outlet square and round two kinds, according to the size of the caliber of dozens of specifications, widely used in metallurgy, carbon, chemical, building materials and other industries.
2, manual plug valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy to install, easy to disassemble, etc., manual screw gate valve can be installed horizontally or vertically, with wear and automatic compensation function of long service life and other characteristics.
3, manual plug valve in the normal use of the process of the transmission parts should be regularly inspected, plus lubricants to do a good job of maintenance.
