The three-valve group consists of a valve body, two shut-off valves and a balancing valve. Operation procedure when the differential pressure transmitter is put into operation: First, open the two drain valves on the differential pressure transmitter, then open the balancing valve, and then slowly open the two shut-off valves to remove the air or dirt in the pressure guiding tube. When the two drain valves are closed, the balance valve is closed and the transmitter can be put into operation. Differential pressure transmitter zero point online calibration operation procedure: first open the balance valve, close the two shut-off valves, you can zero-check the transmitter. Three valve sets can be mated: 3051, 3095, 1151, EJA, FX-2, FCX-A/C and Honeywell ST3000 series transmitters.
The stainless steel three-valve group consists of a valve body, two shut-off valves and a balancing valve. According to the role of each valve in the system can be divided into: high pressure valve, low pressure valve, the middle is the balance valve. When used with a differential pressure transmitter, the function of the high pressure valve and the low pressure valve is to open or disconnect the positive and negative pressure measuring chambers and the pressure guiding point; the function of the balancing valve is to disconnect the positive and negative pressure measuring chambers or Turn on.
When the differential transmitter is put into operation, first open the pressure relief valve on the differential pressure transmitter, then open the balancing valve, then open the two shut-off valves, and wait for the measured medium to drain away from the differential pressure transmitter. After the air, close the two pressure relief valves, then close the balancing valve, and the differential pressure transmitter can be put into operation.
The three-valve group has excellent high and low temperature performance, good pressure resistance, no curing, no dissolution, no dispersion.
The three-valve group is suitable for insulation of motors and electronics, sealing of semiconductors, waterproofing of electrical insulators, anti-conduction, anti-flashing, high-voltage electronic connection systems and electrical equipment to prevent moisture from entering, preventing corona release and arc elimination, and also for Release film, waterproof, damping, shockproof, anti-oxidation, etc.
