Hardware vacuum valve purchase guide
Hardware vacuum valve is in the vacuum system, which is used to change the direction of air flow, adjust the air flow, cut off or connect the pipeline.
The following is a brief introduction to the vacuum valve:
High vacuum gate valve driver can be placed on the side
In general, the height of the gate valve is high, which has the disadvantage of occupying a large space of equipment height. In order to overcome this disadvantage, we design the driving device on the side, which greatly shortens the height and size of the valve, and reduces the manufacturing cost of the equipment space.
High vacuum butterfly valve adopts high platform design
Generally, the pneumatic and electric high vacuum butterfly valve adopts the installation mode of bracket / connecting sleeve. The high platform designed by our company makes the installation of actuator simple.
The valve bodies of small caliber high vacuum flapper valves are all precision castings
The high-tech precision casting technology and equipment make the stainless steel casting completely able to obtain the dense structure. There are no casting defects such as porosity, porosity and sand inclusion. Clean and beautiful appearance.
The leakage rate index of valve body is better than 10-10pa.m3/s. It is suitable for ultra-high vacuum condition.
The performance of gyc-jq series electromagnetic high vacuum differential pressure charging valve to prevent oil return is greatly improved
After improving the structure of high vacuum differential pressure charging valve, the product performance is more reliable and more suitable for the working condition of mechanical vacuum pump.
The following three key capabilities have been improved:
(1) The valve closing time is shortened to less than 0.7 seconds, which is more conducive to prevent oil return;
(2) The valve can only be opened when the vacuum degree reaches a certain value. If there is no pressure difference, it will return to the normally open state;
(3) . the vacuum leakage rate index of the product has been improved from the original low vacuum value to the high vacuum value, which can fully meet the requirements of high vacuum conditions, such as the safety valve used as the air inlet of the rotary vane pump with higher requirements.
Unique one-piece high-quality air conditioning ball valve throttling port with better speed regulation
The integrated high vacuum regulating ball valve adopts V-shaped orifice to make the regulating pumping speed more superior. It is installed on the main pumping pipe of the single crystal furnace to regulate the pumping speed of the furnace body, changing the old combination form of "butterfly valve + baffle valve".
The coils of gdc-j electromagnetic high vacuum flapper valve and DDC-JQ electromagnetic vacuum charging valve will not generate high temperature after being energized for a long time
Scientific circuit control and electromagnetic circuit design make the solenoid valve coil always work in the state of high efficiency and power saving. Under the condition of room temperature 30 ℃, the coil surface temperature is ≤ 55 ℃ for 72 hours, and the product shell temperature is lower. And the electronics don't heat up. This will never cause the coil to burn out.
