Stop valve of pressure gauge , also known as pressure gauge Globe valve The pressure gauge valve is easy to install and disassemble, and the connection is tight. It is the function of opening or cutting off the pipeline of instrument measuring pipeline system. jj。 M1 pressure gauge stop valve is an adjustable valve. It has good sealing performance. It is generally applicable to gas or liquid media with low flow rate, high temperature and high pressure, and also suitable for use with pressure gauge.
The utility model has the advantages of convenient installation and disassembly, close connection, good fireproof performance, high explosion-proof and pressure resistance capacity, good sealing performance, etc., and is an advanced method for measuring and connecting valves in power station, oil refining, chemical equipment and instruments.
Technical parameters of stop valve of pressure gauge
Working pressure: ≤ 32Mpa;
Operating environment temperature: - 20 ℃ - + 200 ℃;
Size: dn5 M20 × 1.5-m20 × 1.5 dn5m20 × 1.5-g1 / 2;
Connection structure: the internal thread of pipe joint needs to be connected;
Pressure gauge Instrument valve It has the advantages of convenient installation and disassembly, fastening, fireproof, explosion-proof, high-pressure resistance and good sealing performance. It is the connecting valve in power station, oil refining, chemical plant and instrument measuring pipeline.
The movement track of the stop valve disc of the pressure gauge is parallel to the flow channel, and the motion track of the gate valve disc is vertical to the flow channel. The flow rate is different, the gate valve needs to be fully opened, and the stop valve is not required. There is no requirement for inlet and outlet direction for gate valve, and there are inlet and outlet regulations for globe valve!
The sealing performance of some good valves is calculated, but the scale is generally not large, and the size of the valve can be made very large. However, from the point of view of shorter than valve, high temperature shut-off valve, especially lift rod valve, needs higher height space.
