The straight pipe sections installed before and after the flow meter can ensure that the fluid flow state in the pipeline is uniform, which does not directly affect the measurement accuracy of the flow meter, achieving good measurement results.
Quickly open the blind plate.
The quick-opening blind plate is a fixed quick-opening device set at the pipe opening for cleaning, unblocking pipelines, and inspecting and clearing containers.

RQJ/*/* F-QZFS* series axial flow shut-off valve
The RQJ/*/*F-QZFS series gas safety shut-off valves are axial flow structure safety shut-off valves. This series of products has a flow path direction that is consistent with the pipeline gas flow direction, featuring advantages such as high flow capacity, high precision, good sealing performance, and fast response speed. It can achieve overpressure and low-pressure protection functions. Applicable media: natural gas, artificial coal gas, liquefied petroleum gas, and other non-corrosive gases.
RQJ/*/*F-QZQS* series gas safety shut-off valve
The RQJ/*/*F-QZQS series gas safety shut-off valves are used in gas transmission and distribution systems. When the pressure of the pipeline controlled by the shut-off valve is higher or lower than the set shut-off pressure, the RQJ safety shut-off valve can urgently cut off the gas flow in the pipeline to protect downstream equipment. Applicable media: natural gas, artificial coal gas, liquefied petroleum gas, and other non-corrosive gases.
RFZ/*/0.4L-QZF* series exhaust valve
The RFZ/*/0.4L-QZF* series relief valve is a direct-acting relief valve, primarily used as a safety device in medium to low pressure regulating systems. When any abnormality in the system causes the monitored pressure to reach a predetermined warning value, this device quickly and automatically relieves the pressure, stabilizing it within a specified range. This series of products features a compact structure, fast response, reliable performance, and good sealing capabilities.
RTZ20/0.6-QZG* series (building) pressure regulator
RTZ20/0.6-QZG* series (building) pressure regulator*: 25/50/70/100 QZG series building pressure regulators are direct-acting pressure regulators equipped with two-stage pressure regulation, overpressure relief, and overpressure cut-off functions. The QZG series building pressure regulators are suitable for gas pressure regulation for small flow, medium to low-pressure residential users and small commercial users. They have advantages such as compact size, ease of operation, and high pressure stabilization accuracy. They can be used for liquefied petroleum gas, natural gas, artificial coal gas, and other media. The QZG series building pressure regulators generally feature right-angle threaded connections but can also be connected with horizontal threads or flanges.
RTZ50/0.6-QZGB17* series pressure regulator
The RTZ50/0.6-QZGB17* series pressure regulator is a direct-acting pressure regulator. It is suitable for gas pressure regulation systems for residential users and medium-sized commercial users. It features a modular design, including the main valve body, main regulating valve, and shut-off valve. This design offers advantages such as simple structure, easy disassembly, and convenient maintenance. The regulator uses an internal balanced valve structure, which ensures that the outlet pressure is not affected by changes in inlet pressure.
RTZ50/0.6-QZGA30* series pressure regulator
The RTZ50/0.6-QZGA30* series pressure regulator is a direct-acting pressure regulator suitable for gas pressure regulation systems for residential users and medium-sized commercial users. It features a modular design, including the main valve body, main regulating valve, and shut-off valve. This design offers advantages such as simple structure, easy disassembly, and convenient maintenance. The regulator uses an internal balanced valve structure, which ensures that the outlet pressure is not affected by changes in inlet pressure.
