Gas valve device with flow monitoring function

Abstract

The invention discloses a gas valve device with a flow monitoring function. The gas valve device with the flow monitoring function comprises a valve body, an air inlet is formed in one side of the valve body, and an air outlet is formed in the other side of the valve body; a valve seat is embedded in the upper surface of the valve body; a monitoring meter is embedded in the side, close to the valve seat, of the upper surface of the valve body; the surface of the monitoring meter is coated with a fluorescent layer; and a mounting cover is rotationally connected to the top end of the monitoringmeter through hinges. Through arrangement of the monitoring meter, flow monitoring can be carried out on gas passing through the valve body, so that a user accurately masters the gas flow rate of thevalve; through arrangement of a first pressing block, a second pressing block and a rotary shaft, a valve rod can be protected conveniently, and the service life of the valve rod can be prolonged; andthrough arrangement of a screw rod, an elastic part, a first side plate and a second side plate, extrusion between the first side plate and the second side plate can be firmer conveniently, and the surfaces of the first pressing block and the second pressing block can be effectively protected conveniently.

Description

technical field [0001] The invention relates to the technical field of gas valves, in particular to a gas valve device with flow monitoring. Background technique [0002] The gas valve is an important component on the compressor cylinder. It is responsible for the suction and discharge of gas. The traditional gas valve is composed of a valve seat, a valve plate, a spring, a lift limiter, and bolts. The gas valve is used in daily life, transportation tools, etc. Even a valve that is widely used on aircraft, in some special occasions, the required air pressure is extremely high, so the common gas valves in daily life are difficult to meet the requirements, especially when used in highly flammable gases such as oxygen and combustible gas. Insufficient rated pressure will bring unpredictable consequences, [0003] A Chinese patent discloses a gas valve. (Authorized Notification No. CN202418643U).

[0002] The gas valve is an important component on the compressor cylinder. It is responsible for the suction and discharge of gas. The traditional gas valve is composed of a valve seat, a valve plate, a spring, a lift limiter, and bolts. The gas valve is used in daily life, transportation tools, etc. Even a valve that is widely used on aircraft, in some special occasions, the required air pressure is extremely high, so the common gas valves in daily life are difficult to meet the requirements, especially when used in highly flammable gases such as oxygen and combustible gas. Insufficient rated pressure will bring unpredictable consequences,

[0003] A Chinese patent discloses a gas valve. (Authorized Notification No. CN202418643U). This patented technology can realize the closing of the gas valve through the hard seal between the valve core sealing surface and the mating surface. Compared with the existing valve core and valve body The soft-sealed gas valve between them greatly increases the air pressure it can withstand, so that it is suitable for occasions with high air pressure and solves the problem of low working pressure of the existing gas valve. However, the device does not have a The monitoring meter cannot monitor the flow rate of the gas passing through the valve body, and cannot accurately know the gas flow rate of the valve. It is not convenient for the user to adjust the valve. There is no first pressing block, second pressing block and rotating shaft, and it is not convenient to protect the valve stem. function, can not prolong the service life of the valve stem, there is no screw, elastic member, first side plate and second side plate, it is not convenient to fasten or loosen the first pressing block and the second pressing block, and it is not convenient to tighten the valve Effective protection for rods
