China Gate Valve Introduction

Gate valves made of speclal rubber elastlcly  full wrap-plece valve structure, and the general absence of gate  leakage or rust compared to other phenomena. Overcome their  common seal bad, elastic fatigue, wear rubber aging and Sealing ruts and other defects、 Produced by ths elastic saeling full  compensation of small quantities of deformation to achieve a  good sealing effect. It can be widely used in water supply,  petrochemical, metallurgy, shipbuilding, food, pharmaceuticals  and energy systems and other fluid line is used as a regulator  and shut-off devices.


China Gate Valve Features

1. The overall package of plastic: the spool and the latest high-performance rubber vulcanization technology overall   coating. laminating are tight. accurate geometry, rellable sealing and long service life.

2. Light weight: body ductile iron material, gate valve to reducs weight than tha average 25%, easy installation and   maintenance; gate valve maximum opening helght is generally low 60mm ~ 280mm, can be Installed where space   is llmited.

3. Flat style seat: The bottom of the pipe the same flat style seat design, does not produce debris accumulation, flow   channel unimpeded and reliable sealing.

4. Corrosion resistance: the valve cavity using non-toxic epoxy powder coating, inner parts mining copper alloy and   stainless steel to prevent corrosion and rust.

5. The three 'O' seal: the use of the stem seal O-ring seals, friction is small, lightweight and watertight gwitch.

Precautions for the use of China Gate Valve


1. For the manual door of the thermal system, it should be tightened again after half an hour after the operation is completed to eliminate the valve gap caused by thermal expansion and contraction.


2. For thermal pipelines with primary and secondary doors, the valve operation sequence is: when opening, the door should be opened first, then the second door; when closing, the second door should be closed first, and then the door should be closed again.


3. For the operation of the gate valve, it can only be fully closed or fully open, and half open and half closed are not allowed to reduce blow damage to the valve.


Precautions in valve management


1. Before starting the unit, carry out the test of each electric and pneumatic valve. During the test, a special person should monitor the movement of the valve and baffle on the spot, check that the actuator connecting rod and pin should not be loose, bend or fall off, and check the DCS The opening indication should be consistent with the local indication, and the electric door with intermediate stop should be tested for normal intermediate stop. Adjust the door switch in the correct direction and move flexibly. Those with interlock circuits should conduct interlock tests with relevant professionals. The pneumatic adjustment device should be flexible and free of air leakage and abnormal phenomena. If an abnormality occurs during the test, the test should be stopped and notified in time. Maintenance personnel handle it.


2. Each time the unit is started, the corresponding operation should be carried out in strict accordance with the "Operation Ticket". Each drain gate should be inspected and closed according to regulations. After each drain gate is closed 6 hours (within 10 hours), there will be a temperature indicator behind the drain gate. If there is no internal leakage of the valve, it should be judged according to the analysis of the pipe temperature indication behind the valve. If there is no temperature indication behind the drain gate, use an infrared thermometer to measure the temperature of the pipe wall before and after the valve or use the feel to judge whether the valve has internal leakage. If the electric or pneumatic valve leaks internally, the drain electric door or the manual isolation door in front of the pneumatic door should be closed. For drain electric or pneumatic doors without manual isolation door, if the internal leakage is large, the electric door should be manually closed. And register the vacancy and contact the maintenance processing. If the manual door leaks inside, please log in and contact for maintenance.


3. Before each unit shutdown, a comprehensive inspection of valve defects (leakage) should be carried out, the leaking valve should be registered and the relevant maintenance department should be notified.


4. During the process of opening, stopping or draining water under pressure, after the drain (drain) gate is opened, check whether there is temperature behind the valve or throttle (trap) to ensure that it can drain (drain) the water and prevent Corrosion caused by water accumulation in heating pipes caused by clogging of valves or pipes or orifices (traps).
