AI Technical Summary
The existing four-way gas distribution panel has unstable back-end pressure during use, with large pressure fluctuations, which cannot continuously meet the gas demand of the equipment.
The system employs a multi-stage pressure regulator, consisting of a first diaphragm valve, a high-pressure gauge, a first-stage pressure reducing valve, and a low-pressure gauge, installed sequentially on the main pipeline. A second diaphragm valve is installed on the venting pipeline, and a second-stage pressure reducing valve is also installed on the main pipeline. Pressure stability is achieved through multi-stage pressure reducing valve regulation. The addition of a second-stage pressure reducing valve ensures pressure stability. Combining compression fittings and threaded connections improves connection performance and sealing. A flame arrester is installed to prevent combustion and backflow.
This achieves stable backend pressure, reduces pressure fluctuations, continuously meets the gas demand of the equipment, and improves the reliability and security of the connection.

Technical Field
[0001] This utility model relates to the field of gas distribution, specifically a four-way gas distribution panel. Background Technology
[0002] The four-way gas distribution panel is a device used to distribute gas, which can supply gas to four channels simultaneously, meeting the needs of multiple devices at the same time.
[0003] However, the pressure at the back end of the existing four-way gas distribution panel is unstable during use, with large pressure fluctuations, which cannot continuously meet the gas demand of the equipment. Utility Model Content
[0004] To achieve the above objectives, the present invention aims to provide a four-way gas distribution panel that can solve the problems existing in the background art. The present invention provides the following technical solution:
[0005] A four-way gas distribution panel includes a main body with a main pipeline and an exhaust pipeline mounted on it. The main pipeline is sequentially equipped with a first diaphragm valve, a high-pressure gauge, a first-stage pressure reducing valve, and a low-pressure gauge. The exhaust pipeline is equipped with a second diaphragm valve. A second-stage pressure reducing valve is also installed on the main pipeline, located between the low-pressure gauge and the outlet of the main pipeline. In this product, the first diaphragm valve controls the gas circuit switch of the main pipeline, the high-pressure gauge displays the high-pressure end gas circuit pressure, and the first-stage pressure reducing valve regulates the internal pressure of the main pipeline, thereby achieving a stable flow output and low-pressure... The pressure gauge displays the low-pressure end gas pressure, the secondary pressure reducing valve is used for secondary pressure regulation to stabilize the pressure inside the main pipeline, and the second diaphragm valve is used to control the opening and closing of the exhaust gas pipeline. The working process of this product is as follows: When gas enters the main pipeline, the first diaphragm valve is in the closed state. Open the gas cylinder, open the second diaphragm valve for 2-3 seconds, repeat 3 times, and ensure that there is no residual air inside the pipeline. Then close the second diaphragm valve, open the first diaphragm valve, adjust the first and second pressure reducing valves clockwise to the operating pressure, and then open the control valve at the rear end. Only then can the gas circuit be used normally.
[0006] As a further embodiment of this utility model: the first diaphragm valve, the first-stage pressure reducing valve, the second-stage pressure reducing valve, and the second diaphragm valve are all connected to the main body by compression fittings, which provides good connection performance and sealing.
[0007] As a further embodiment of this invention: both the high-pressure gauge and the low-pressure gauge are fixed to the main body by threaded connection, making them less likely to fall off.
[0008] As a further embodiment of this utility model: both the high-pressure gauge and the low-pressure gauge are fixed to the main body using NPT threaded connections, which provides good sealing, pressure resistance, and corrosion resistance, and facilitates installation.
[0009] As a further aspect of this utility model, a flame arrester is also installed on the main body to prevent combustion inside the gas pipeline and to prevent gas backflow.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This product features an added two-stage pressure reducing valve, which makes the downstream pressure more stable, continuously meeting the equipment's needs with minimal pressure fluctuations. Attached Figure Description
