Safety type fuel gas pressure regulating box

Abstract

The invention discloses a safe gas pressure regulating box, which comprises a box body, an inlet manifold is arranged at the bottom of the box body, a corrugated compensator is arranged on a flange, a first flow meter is arranged on one side of the filter, and a first One side of the flowmeter is provided with a second flowmeter, the bottom of the second flowmeter is provided with an overpressure divergence valve, one side of the second flowmeter is provided with a pressure regulator, and the bottom of the pressure regulator is provided with an overpressure cut-off valve, There is a third flowmeter on one side of the pressure regulator. The flowmeters on the three different pipelines can check the position of the pipeline leakage. The overpressure divergence valve can reduce the pressure of the pressure regulator. The gas released by the pressure divergence valve will not cause the danger of explosion. When the temperature in the box is high, the cooling device and the shutter can form air convection, and the cooling device will cool down the internal environment of the box to avoid the danger of gas expansion. The entire pressure regulating box The structure is simple, and the safety factor of its use is enhanced.

Description

technical field [0001] The invention relates to a gas pressure regulating box, in particular to a safe gas pressure regulating box. Background technique [0002] The gas pressure regulating box is an important part of the gas transmission and distribution system. Its main function is to adjust and stabilize the pressure of the gas system, and to control the gas flow of the gas transmission system to ensure the safety of the gas transmission system. Due to the change of the gas pressure in the gas pressure regulating box It is directly related to the normal operation of the gas transmission and distribution system. Once the gas pressure in the gas pressure regulating box is abnormal, the gas transmission and distribution system needs to be debugged in time to eliminate the fault. The gas flow of the pressure box should also be monitored for the gas flow of the gas pressure regulating box. Therefore, it is necessary to provide a gas pressure regulating box capable of monitorin...

Problems solved by technology

[0003] However, when the overpressure diverter valve discharges too much gas, the gas cannot be discharged, causing the gas to accumulate in the small space of the box. When the weather is relatively dry and hot, it is very easy to explode, and when the pipeline leaks, it is impossible to call the police in time Remind the maintenance personnel, and when the pipeline is repaired in the later stage, there are many pipelines, and it is impossible to detect the specific leakage location, which brings difficulties to the maintenance
