Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories
Three-Valves Manifold Pressure Transmitter Accessories made of stainless steel are frequently used in automatic control systems in the chemical, metallurgical, textile, petroleum, and electrical power industries. The three-valve group uses a non-rotating valve stem, a working thread that does not come into contact with the system medium, and a forged valve body that was created using foreign product technology. It is of excellent quality, has a lovely appearance, and an exceptional shape. It is the perfect transmitter for differential pressure. supplementary goods
1.Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories
Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories are widely used in automatic control systems in electric power, petroleum, chemical industry, metallurgy, textile and scientific research departments. The three-valve group adopts the forged valve body designed by introducing foreign product technology, adopts the working thread that does not contact the system medium, and the non-rotating valve stem design. It has exquisite shape, beautiful appearance and high quality. It is an ideal differential pressure transmitter. supporting products.
2.The features of Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories
The stainless steel three-valve group is exquisite in structure, beautiful in appearance, beautiful in safety, easy to install, and has good sealing performance. It does not need to be equipped with additional pressure joints. It can be butt-welded with ￠14 pipes or plug-in welded with ￠10 pipes. At the same time, in places where fire cannot be fired, a ferrule-type three-valve group can be used, and a ￠14 tube can be directly inserted into the ferrule, and then the nut can be tightened to seal it for use.
3.The working principle of Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories
The left side is the high-pressure valve, the right side is the low-pressure valve, and the middle is the balance valve. When the high and low valves are closed and the balance valve is opened, the pressure in the positive and negative pressure measurement chambers is balanced. When the high and low pressure valves are opened and the balance valve is closed, the pressure at the input end is respectively For high and low pressure. When the instrument is maintained and zeroed, only the positive and negative pressure valves need to be closed to proceed.
4.The operating procedures of Stainless Steel Instrumentation Three-Valves Manifold Pressure Transmitter Accessories
The operating procedure when the integrated three-valve group and differential pressure transmitter is put into operation: First, open the two blowdown valves on the differential pressure transmitter, then open the balance valve, and then slowly open the two shut-off valves to drain the Remove the air or dirt, close the two drain valves, and then close the balance valve, the transmitter can be put into operation. The operation procedure of zero point online calibration of differential pressure transmitter: first open the balance valve, close the two shut-off valves, and then the zero point calibration of the transmitter can be carried out.
