Description

Overview

Seal gate valves of the elastic base seat is also called lifting lever gate valve (also called rising stem gate valves).Usually in lifting lever on the trapezoidal thread, through the valve at the top of the nut and guide groove on the valve body, the rotation movement into linear motion, which is the operating torque thrust into operation.Open valve, when the gate hoisting height is equal to valve size 1:1 times, fluid channels open completely, but at runtime, the position cannot be monitored.Actual use, is the stem apex as a sign, that is fixed position, as its full open position.To consider locking phenomenon in a temperature change, usually in the open to the vertex positions, pour 1/2-1 ring back, as the full open position of the valve.Valve in full open position, therefore, according to the location of the damper (namely travel > to determine.

Non-rising stem seal gate valves of the opening and closing of the elastic base seat is ram, ram movement direction perpendicular to the direction of flow and the valve can only be fully open and close, not to adjust and throttling.Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 ° 52 ' ' ' '.Wedge gate valve of the damper can be made into a whole body, is called a rigid disc;Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, the gate is called elastic disc, generally for flange connection.

Product structure features

One-piece copper nut

Valve core of the copper nut and ductile iron skeleton, using special technology closely connected as a whole, to ensure the long-term operation and it will not loosen under running water, avoid to cause the valve control failure.

The special seal

Between the valve stem and valve cover sealing structure, adopt three o ring design, compared with the traditional packing seal structure of gate valve, tight across the friction resistance.In the valve in any opening, pressure and have stem safety lock function, to ensure that the stem will not be in the process of operation and maintenance of the pressure out, avoid to cause injuries

The whole package plastic valve core

Ductile iron skeleton inside and outside the high-performance rubber and vulcanized with the latest technology is adopted to improve the overall coating, laminating tightly solid, geometric size accurate, sealing good elasticity, complete isolation valve core metal and fluid, corrosion resistance.
