The Production Introduction

Pneumatic American Standard Gate Valve
Pneumatic gate valve is with pneumatic actuator (double cylinder, and with a buffer mechanism) and manual and its protection mechanism (manual and self-locking pneumatic to manual conversion device) low stand stem gate valve. Due to the double cylinder structure, the valve and the single cylinder type gas.

Purpose And Scope Of Use
Pneumatic standard gate valves are low stand stem gate valves with pneumatic actuator (double cylinder, with buffering mechanism) and manual and its protection mechanism (manual and self-locking pneumatic to manual conversion device). The valve adopts double cylinder structure, compared with the single cylinder pneumatic gate valve, the lifting force increases twice. This fundamentally solves the problem that some of the valve bodies of single cylinder pneumatic gate valves are dead and can not be opened. And, because the valve has a buffer mechanism, can effectively slow down the valve when closing the valve, due to the downward impact of the piston caused by the valve plate car sealing surface and valve body sealing surface wear, at the same time, can also avoid the phenomenon of gate stuck. To cooperate with users to realize the automatic operation, zhongtai company in addition to supply the series of products, can also provide individual cylinder block, including support, help the user to modify the existing varieties of manual gate valves, install two cylinder actuator part in manual valve body big cover, can constitute a duplex pneumatic - amphibious gate valve manually. Because of its advanced technology, reliable performance, convenient operation and maintenance, it has been widely used by petroleum, chemical, metallurgy, electric power, shipping and other departments as the pipeline to transport gas, liquid medium opening and closing device.

The performance parameters
Operating temperature 425 (ºC) 150lb-600lb (Mpa)
Applicable medium air, water, steam, oil and nitric acid, acetic acid and other corrosive fluids nominal diameter 50-800 (mm)
Material carbon steel connection type flange
Pneumatic manual gate valve is applicable to petroleum, chemical, metallurgy, electric power, sea transportation
Model Z6S40Y-300LB brand Zhitai

Structure principle
The series of products produced by the company use 0.4 ~ 0.7mpa (gauge pressure) purified compressed air as the working pressure, push the piston, drive the gate for vertical to the fluid displacement, to realize the purpose of opening and closing the valve. The working principle of the double-layer cylinder and the buffer mechanism is described as follows according to the four stages of the ram:

1. Gate valves open before stage: the upper cylinder piston (hereinafter referred to as the piston) and the lower cylinder piston (hereinafter referred to as the piston) force at the same time, the valve stem in upper and lower piston, driven by the lifting force almost two times in a single piston, overcome the gate seal face and body, between the maximum static friction force drives the ram up. Compressed air from the lower chamber of the upper cylinder, through a specific channel arranged in the partition board, through the connecting pipe, to the lower chamber of the lower cylinder, to push the upper and lower pistons at the same time. The gas in the upper chamber of the lower cylinder passes through another specific channel arranged in the baffle plate. Unimpeded discharge cylinder outside the body.

2. The later stage of gate valve opening: after the gate is slightly opened, the lower piston will run to the top dead point, and the gate will continue to lift under the drive of the upper piston until it reaches the fully open position.

3. Gate valve closing stage: driven by the upper piston, the gate leaves the fully open position and begins to descend.

4. After the gate is closed: when the upper piston encounters the lower piston boss, and drives the lower piston to continue to fall together, the intake channel of the upper air chamber of the lower cylinder and the exhaust channel of the lower air chamber of the lower cylinder are obstructed, obviously slowing down the downward speed, and the gate falls to the full closed position. Slow down the impact of the gate, can close the valve by itself, and do not make the valve plate wedge too tight, at the same time, but also protect the sealing surface from damage caused by violent impact. Pneumatic - manual conversion mechanism, flexible and reliable in the upper cylinder cover pneumatic - manual conversion, in any location on the closing of the valve open process, can be very convenient rotation operation handle, directly by air to manually or conversion from manual to pneumatic mode of operation, the transformation handles the self-locking positioning pin type design, handle positioning, reliable stabilization. When the solenoid valve and its control circuit or the air supply system fails, it can be quickly converted into manual operation without other auxiliary tools to ensure the normal operation of the line and avoid accidents. Before the completion of the self-control system of the new project, this series of gate valves can be reliably used as manual gate valves, with flexible and quick action. Valve closing time adjustable By adjusting the buffer mechanism mounted on the baffle plate, the gate closing time can also be adjusted within a certain range.

Pneumatic Non - Stem Knife Gate Valve
Pneumatic dark rod knife valve is a new kind of gate valve, small volume, light weight, light material saving, is sewage, coal slurry, mud, air, slag water mixture, water supply, paper making, mining and other industries in the ideal products.

Knife gate valves are metal to metal hard seal or metal to rubber soft seal. During opening and closing, the gate and sealing face are specially designed for less friction and durability.

The upper seal of this knife-shaped gate valve breaks through the conventional sealing form, and adopts the upper cover structure, which makes the upper seal changed from a large rectangular seal to a small circumferential seal, and the sealing performance is greatly improved. On the basis of circumferential seal, advanced floating seal structure is adopted to make the upper seal reach the same life as the pipe, thus improving the service life of the valve as a whole.

With a jacket on top of the handwheel, the gate valve keeps all the moving parts of the valve closed, and the screw drive of the gate and stem does not become stuck due to dry lubricating oil. Especially suitable for long-term normal operation in dust and dry harsh environment.
