The pressure gauge three-way plug is made of all brass material and is installed between the pressure gauge and the buffer pipe. It is suitable for temperatures ≤ 200 ℃ and pressures PN0.6. The main technical parameters of the 301 pressure gauge three-way plug are nominal pressure PN0.6MPa strength test pressure 1.0 sealing test pressure 0.6 working temperature ≤ 150 ℃ working medium: water, steam, oil code pipe thread G1 pressure gauge thread G2 size (mm) Remarks LL1L2H301A1/2 "M20 × 1.565502637 Part material: brass.
The function of pressure gauge three-way plug
1, It is beneficial for flushing the sewage, scale and other debris in the water storage bend, avoiding dirt blocking the bend and ensuring the smooth flow of the entire pipeline.
2, When the three-way valve is closed during normal operation of the boiler, the passage between the pressure gauge and the boiler can be cut off, and the pressure gauge can be repaired or replaced to ensure its accuracy, sensitivity, and reliability.
3, A plug valve is composed of a valve body and a valve plug. The valve plug has three 90 degree channels, and the outer end has an adjustment handle for the three-way plug valve. There is a "T" shaped mark on the handle indicating the direction of the valve plug passage, so that the stoker can identify its connection direction during operation and avoid accidental closure, which may cause the pressure gauge to have no indication.
