Abstract

The invention provides a gas cylinder valve and a gas cylinder group. The gas cylinder valve comprises an installation body and an electromagnetic valve, the installation body is provided with a main channel penetrating through the two ends of the installation body, a gas inlet is formed in one end of the main channel, a gas outlet is formed in the other end of the main channel, and a one-way valve only allowing gas to enter the main channel is arranged at the gas inlet or a pipeline used for communicating with the upstream of the gas inlet. The installation body is further provided with a first valve hole, the first valve hole communicates with the main channel, and the installation body is further provided with an inflation and deflation channel used for communicating with the interior of a bottle body of a gas bottle; and the electromagnetic valve comprises a first valve seat detachably installed in the first valve hole and a first valve element detachably installed in the first valve hole, the first valve seat is provided with a first gas hole communicating with the main channel, and a first sealing ring forms sealing between the first valve seat and the first valve hole. According to the gas cylinder valve and the gas cylinder group, the valve seat and the valve element are detachably installed on the installation structure through a gas adding valve and the gas bottle, and the problem that an existing valve seat cannot be maintained after sealing fails is solved.

Description

technical field [0001] The invention relates to the field of gas storage, in particular to a gas cylinder valve and a gas cylinder group. Background technique [0002] On vehicles or equipment that need to use gas fuel, a gas cylinder for storing fuel gas needs to be installed. The gas cylinder is provided with a gas cylinder valve, which is used to receive gas when inflating the gas cylinder and release gas when using gas fuel. In order to achieve reliable sealing, the valve seat is generally processed directly on the hole wall, but this processing method is complicated and laborious, and once the valve seat is damaged, the entire valve will be scrapped. [0003] In addition, the structure of the existing temperature-sensing and pressure-relief valve leads to a large length of its protruding into the installation body. Due to the limited installation position of the installation body, the position of the pressure relief port cannot face the flow hole of the pressure relief ...
