How much is the valve phone

For high-vacuum gate valves and throttle valves, check and adjust the fully open or fully closed indication position. The rising stem gate valve and globe valve should also use their fully open and fully closed positions to prevent When the nozzle is fully open, when the valve is fully closed, you can use the ruler and marks to find that the sealing part has fallen or resisted foreign objects to troubleshoot. The pipeline and equipment of the new installation have more internal dirt, welding ballast, etc. There are simple dirt on the sealing surface of the manual valve. Use the micro-opening method to let the high-speed medium wash away these foreign objects.

Valve mass flow meter, namely MASSFLOWMETER (abbreviated as MFM), vacuum valve is an instrument for measuring gas flow, its measured value is not inaccurate due to temperature or pressure fluctuations, and does not require temperature and pressure compensation, mass flow controller, that is Massflowcontroller (abbreviated as MFC), not only has the function of mass flowmeter, but more importantly, it can automatically control the gas flow, that is, the user can set the flow according to the needs, and the MFC automatically keeps the flow constant at the set value , Vacuum valve.

Beipiao Vacuum Equipment Co., Ltd. specializes in the research and development, design and production of vacuum valves, vacuum chambers, molecular pumps and molecular pump units with a highly skilled team, and continues to develop new products. Products are widely used in aerospace, technology, coating, solar energy, vacuum furnace industry, energy, metallurgy, chemical industry and many other industries.

The high vacuum flapper valve determines the geometric parameters of the selected valve: structural length, flange connection form and size, valve height dimension after opening and closing, connected bolt hole size and number, overall valve outline size, etc., determine and The nominal diameter and connection method of the valve connected to the pipeline: flange, thread, welding, etc., determine the valve parameters: for automatic valves, first determine the allowable flow resistance, discharge capacity, back pressure, etc. according to different needs, and then determine the nominal flow of the pipeline Diameter and the diameter of the valve seat hole.

High-vacuum flapper valve. The flapper valve is used in the corner and three-way places in the vacuum pipeline. The flapper valve is used in the occasions where the vacuum degree is high or the pipeline size is high. The diaphragm valve and the ball valve are straight-through and can be used in the normal Where pressure and vacuum coexist, the butterfly valve is in straight-through mode. The three driving modes of hand, air and electric are determined by the user. The valve stored for a long time should be checked regularly to clean up the dirt and apply anti-rust oil on the processing surface. , Should be checked regularly, the first check item: the wear condition of the sealing surface.

The main service groups of Beipiao Vacuum Equipment Co., Ltd.: colleges and universities; research institutes; customers with high vacuum and ultra-high vacuum requirements. The company takes scientific development, forge ahead, the pursuit of excellence, and casting fine products as the development concept. "Customer first, service first" is the business policy.

High-vacuum valve vacuum valve compression fittings provide reliable, leak-proof and sealing connections to avoid vibration, thermal shock, improper installation and serious problems that can cause huge losses. Tube fittings are always detectable and should be installed initially. Later, the use of the gap detection gauge can ensure that the installer or inspector is fully tightened. If the nut has been properly tightened, the detection gauge cannot be placed between the hexagonal end of the nut and the joint body. Sealing is prohibited. Fillers such as glue.

For vacuum valves, check and adjust the fully open or fully closed indication position of the gate valve and throttle valve with the mark. The rising stem gate valve and globe valve should also use their fully open and fully closed positions to prevent them from being fully opened. The dead center of the mouthpiece, when the valve is fully closed, the ruler and marks can be used to find that the closed part has fallen or resisted foreign objects for troubleshooting. The pipeline and equipment of the new installation have many internal dirt, welding ballast and other objects. Normally open the manual valve There are simple dirt on the sealing surface, use the micro-opening method to let the high-speed medium wash away these foreign objects.
