Combined Cylinder Valve

Abstract

A combined gas cylinder valve, belonging to a gas cylinder valve, including a main valve body, the right end of the main valve body is used for threaded connection with the gas cylinder, the main valve body is provided with a main channel and an air outlet channel, and the right end of the main channel is connected with a filter The right end of the main channel communicates with the cylinder through the filter, the main valve body at the left end of the main channel is connected with a one-way valve, and the main valve body between the main channel and the outlet channel is provided with a pressure reducing valve with switch function. The outlet of the channel is connected with a pipe joint, the joint channel on the pipe joint communicates with the air outlet channel, the pipe joint is provided with a safety valve, the main valve body is connected with a pressure gauge, and the pressure gauge communicates with the main channel through the side channel. The advantage of the combined gas cylinder valve of the present invention is that as long as people pull the handle, insert the pin or pull out the pin, they can switch between inflating or delivering gas, which saves the trouble of dismantling and installing the pressure reducing valve. It greatly facilitates people's operation.

Description

Technical field: [0001] The invention relates to a gas cylinder valve, in particular to a combined gas cylinder valve integrated with the functions of a one-way valve, a pressure reducing valve and a safety valve. Background technique: [0002] The commonly used gas cylinder valve usually has only one switch function. The gas cylinder valve and the pressure reducing valve are installed separately. When inflating, remove the pressure reducing valve and inflate the gas cylinder through the gas cylinder valve. The bottle valve is equipped with a pressure reducing valve to output the decompressed gas to the outside. From the above process, it can be seen that when inflating and conveying gas to the outside, people have to dismantle and install the pressure reducing valve cyclically, which is troublesome to operate. Invention content: [0003] The technical problem to be solved by the present invention is to provide a combined gas cylinder valve that does not need to disassembl...

Problems solved by technology

[0002] The commonly used gas cylinder valve usually has only one switch function. The gas cylinder valve and the pressure reducing valve are installed separately. When inflating, remove the pressure reducing valve and inflate the gas cylinder through the gas cylinder valve. A pressure reducing valve is installed on the bottle valve to output the decompressed gas to the outside. From the above process, it can be seen that when inflating and delivering gas to the outside, people have to dismantle and install the pressure reducing valve cyclically, which is more troublesome to operate.
