Abstract

The invention provides a gas valve provided with a pressure measuring device, pertaining to the technical filed of machinery and solving problems such as small application scope caused by inconvenient pressure measurement as the pressure measuring device of the current gas valve provided with a pressure measuring device cannot rotate. The gas valve provided with the pressure measuring device consists of a valve body provided with an air inlet pipe and an air outlet pipe, a valve stem and a valve core which is arranged in the valve body. One end of the valve stem is connected with the valve core while the other end thereof passes through the valve body; the air inlet pipe is provided with a pressure measuring hole, the outside of the air inlet pipe is provided with the pressure measuring device, a valve sleeve is arranged and axially fixed on the air inlet pipe and can rotate along circumferential direction, the pressure measuring device is fixedly connected with the valve sleeve, and a connection structure which ensures that the valve sleeve and the air inlet pipe are mutually sealed and that the pressure measuring hole and the pressure measuring device are always communicated when the valve sleeve rotates along the air inlet pipe in a circumferential manner is positioned between the valve sleeve and the air inlet pipe. The gas valve provided with the pressure measuring device is characterized by simple structure, good sealing performance, wide application scope and being capable of measuring the pressure of the gas of the pipe at any angle.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a valve, in particular to a gas valve with a pressure measuring device. Background technique [0002] At present, gas as a fuel has penetrated into thousands of households, especially in large and medium-sized cities. Pipeline gas has been installed in the kitchen, and the gas valve is a very important part. By controlling the opening and closing of the gas valve, the pipeline is opened or blocked. gas. [0003] When using pipeline gas, especially when cooking, people often encounter that the fire of the gas appliance is not strong or can not be ignited. At this time, people cannot know whether it is caused by insufficient pressure of the pipeline gas or because of caused by its own problems. For this reason, someone installs a pressure measuring device on the intake pipe of the gas valve, and uses the pressure measuring device to detect the gas pressure in the pipeline, so that...
