Hardware vacuum valve introduction

Hardware vacuum valve is in the vacuum system, used to change the direction of the air flow, adjust the size of the air flow, cut off or connect the vacuum system components called the vacuum valve. The following brief description of the vacuum valve:

The high-vacuum flapper valve drive can be placed on the side. Usually the height of the flapper valve is high, which has the disadvantage of occupying a large space in the device height. In order to overcome this drawback we have designed the drive device on the side, which greatly shortens the height dimension of the valve and reduces the manufacturing cost of the equipment space.

The high vacuum butterfly valve uses the high platform design The general pneumatic, electric high vacuum butterfly valve uses the bracket/connection sleeve installation method, our company scientific design direct installs the high platform, causes the installation actuator to become simple.

The small-diameter high-vacuum flapper valve body is a precision casting high-tech precision casting process and equipment, which makes the stainless steel casting fully capable of obtaining a dense tissue structure. There is no casting defect such as "pore, loose, sand inclusion". The appearance is clean and beautiful. Valve body leakage rate index is better than 10-10Pa. M3/S. Fully suitable for ultra-high vacuum working conditions.

The GYC-JQ series of electromagnetic high vacuum differential pressure relief valve to greatly improve the oil return performance through the high vacuum pressure differential type inflatable valve structure, making the product more reliable performance, more suitable for mechanical vacuum pump operating conditions. The following three key capabilities have been improved: (1). The valve closing time is shortened to <0.7 seconds, which is more conducive to preventing oil return; (2). The valve opening time is slightly delayed. Only when the vacuum degree reaches a certain value can the valve open. If there is no pressure difference, it will return to the normally open state. (3). The vacuum leakage rate of the product is improved, from the original low vacuum value to the high vacuum value. It can fully meet the requirements of high vacuum conditions, such as the safety valve for the higher requirements of the rotary vane pump inlet.

Unique integrated high-vacuum adjustment ball valve throttle throttle adjustment speed is more superior integrated high vacuum adjustment ball valve uses V-type throttle port makes the regulation of pumping speed is more superior, installed in the single crystal furnace main exhaust pipe to adjust The pumping rate of the furnace changed the old “butterfly valve + flapper valve” combination.

GDC-J electromagnetic high vacuum flapper valve and DDC-JQ electromagnetic vacuum charging valve coil will not produce high temperature for a long time. The scientific circuit control and electromagnetic circuit design make the solenoid valve coil always work under the condition of high efficiency and power saving. Continuous working at room temperature 30 °C for 72 hours coil surface temperature ≤ 55 °C, the product shell temperature is lower. Furthermore, electronic components do not generate heat. This will never cause burnout of the coil.
