Problems solved by technology

The existing pressure reducing valve has complex structure, high manufacturing cost, and the pressure reducing valve is too large to be installed in a narrow space
[0003] Existing decompression valves, such as a high-pressure natural gas decompression valve disclosed in Chinese Patent Application Publication No. "102052495A", natural gas flows in from the intake end, and enters from the top and bottom direction after passing through the decompression mechanism. When the gas outlet is connected to the cavity, the natural gas will be sprayed onto the cavity wall at this time, causing the natural gas flow entering the gas outlet to be turbulent, which can easily cause flow fluctuations and cause the flame state to be unstable when the user uses it.

Abstract

The invention discloses a bolt-type fuel gas pressure reducing and regulating tube. The bolt-type fuel gas pressure reducing and regulating tube comprises a tube body, a fixing body, a spring, a piston, a blind hole, a gas exhaust hole, a gas feeding strip hole and a regulating bolt, wherein the tube body comprises a low-pressure section and a high-pressure section, one end of the low-pressure section is provided with an outer ring and an inner ring, the inner surface of the outer ring is provided with an internal thread, one end of the high-pressure section is provided with an internal thread which is in thread connection with the outer ring, and the end of the high-pressure section is further provided with a circular ring groove used for containing the inner ring; the fixing body is arranged in the low-pressure section; one end of the spring is connected with the fixing body; the piston is connected with the other end of the spring; the blind hole is evenly formed in the position, located between the outer ring and the inner ring, of the end of the low-pressure section, and the starting end of the blind hole is provided with an internal thread; the gas exhaust hole is formed in the low-pressure section and enables the low-pressure section to be communicated with the tail end of the blind hole; the gas feeding strip hole is formed in the inner surface of the end of the low-pressure section; the regulating bolt is in thread connection with the blind hole. The bolt-type fuel gas pressure reducing and regulating tube can be used for conveniently regulating pressure of output fuel gas.

Description

technical field [0001] The invention relates to the field of gas delivery, in particular to a gas delivery device. Background technique [0002] The gas needs to be kept at high pressure during the transportation process, and the gas pressure needs to be reduced when it is used at the user end. Currently, in order to reduce the gas pressure at the user end, a pressure reducing valve is usually provided on the gas delivery pipe. The existing pressure reducing valve has complicated structure and high manufacturing cost, and the pressure reducing valve has a large volume and cannot be installed in a narrow space. [0003] Existing decompression valves, such as a high-pressure natural gas decompression valve disclosed in Chinese Patent Application Publication No. "102052495A", natural gas flows in from the intake end, and enters from the top and bottom direction after passing through the decompression mechanism. When the gas outlet is connected to the cavity, the natural gas w...
