Description

Technical Field

[0001] The utility model relates to a gas valve. Background Art

[0002] When a pipeline is transporting gas, a valve needs to be installed on the pipeline so that the gas can be cut off, regulated and diverted through the valve. The control handle on the valve is easy to rotate if it is accidentally bumped by non-staff, which may cause the gas in the pipeline to leak easily and cause life-threatening danger. Therefore, a valve lock needs to be installed on the valve.

[0003] However, the process of installing the existing valve lock on the valve is relatively troublesome, thus wasting installation time, and the structure is complex, resulting in high production costs. In view of the above problems, it is urgent to carry out innovative design based on the original valve lock.

[0004] Chinese patent application 202020995610 0 discloses a valve lock for a gas valve, including a valve seat and a pipe sleeve, a valve body is formed on the top of the valve seat, a gas pipeline is fixed to one end of the valve seat by threads, the pipe sleeve is nested on the gas pipeline, a fixing clamp is welded to the bottom of the pipe sleeve, a screw is inserted in the fixing clamp, and a nut is screwed on one end of the screw. The beneficial effect is that the utility model can be installed and used in combination with the valve after the valve is installed by setting the pipe sleeve, the lock buckle and the lock body. This structure requires the sleeve to be installed on the pipeline before it can be locked, which is more troublesome. Utility Model Content

[0008] A connecting nut is provided on the right side of the right connecting pipe, and the connecting nut is integrally formed with the right connecting pipe. The main pipe body is provided with a valve core arranged upward, and a valve handle is provided on the top of the valve core. The valve handle is fixedly connected to the valve core and drives the valve core to rotate within a range of 90°.

[0009] The right side of the valve handle is bent upward to form a vertical plate, and the vertical plate is provided with a second through hole penetrating in a horizontal direction;

[0010] A locking component is provided on the top of the connecting nut, and the locking component is provided with a first through hole penetrating in a horizontal direction, and the second through hole is made to face the first through hole after the valve handle is rotated;

[0011] A lock rod of a lock is locked in the second through hole and the first through hole.

[0012] Optionally, the locking component is an "L"-shaped component in longitudinal section, the bottom of which is connected to the plane of the top of the connecting nut by two screws;

[0013] The first through hole is disposed on a vertical plane.

[0014] Beneficial Effects

[0015] The gas valve has good integrity and only needs to be locked with a lock when in use. There is no need to install an additional sleeve on the pipeline, which is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
