Valve locking device

Abstract

The utility model relates to the field of locking devices, in particular to a valve locking device which comprises a valve body, a valve rod, a handle, an anti-skid sleeve, a threaded hole A, a threaded hole B and a fixing bolt. A valve rod for controlling opening and closing of the valve is mounted at the upper end of the valve body; a handle sleeves the upper end of the valve rod; the tail end of the handle is fixedly connected with an antiskid sleeve; a threaded hole A is formed in the upper end of the valve rod; a threaded hole B is formed in the upper end of the handle; fixing bolts for fixing the valve rod and the handle are in threaded connection with the inner sides of the threaded hole A and the threaded hole B; when the valve rod is exposed too long, the top of the valve rod can be firmly attached to the handle, the phenomenon that the handle is not firmly fixed due to the fact that a traditional valve rod is higher than the uppermost edge of the handle is avoided, and meanwhile the plastic rubber sleeve at the tail of the handle not only increases operation comfort, but also greatly increases identification degree due to the fact that exclusive trademarks, models and the like can be designed.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of locking device, especially valve locking device. BACKGROUND

[0002] Firstly, there are various designs of valves and handles in the market, and some valve designs do not consider the fixing requirement of the handle, which leads to easy falling or loss of the handle, and after the handle is lost, the valve cannot be normally operated, which further affects the overall performance and safety of the equipment.

[0003] Secondly, some handles are connected with the valve through an indirect way (such as a connecting piece, an adapter, etc.), and the inconsistency of the exposed length of the valve rod after connection leads to that the handle cannot be tightly and stably connected with the valve, and long-term use may cause wear and damage of the connection part, which further reduces the fixing effect of the handle and the service life of the valve.

[0004] Therefore, in view of the problem that the existing handle cannot be connected with the valve together, the handle on the valve is lost, and after the existing handle is connected with the valve together through an indirect way, the exposed length of the valve rod after connection is inconsistent and does not match, which causes that the handle cannot be fixed firmly and affects the use performance, a valve locking device can be designed. CONTENT OF THE UTILITY MODEL

[0005] In order to overcome the problem that the existing handle cannot be connected with the valve together, the handle on the valve is lost, and after the existing handle is connected with the valve together through an indirect way, the exposed length of the valve rod after connection is inconsistent and does not match, which causes that the handle cannot be fixed firmly and affects the use performance.

[0006] The technical scheme of the utility model is as follows: a valve locking device, comprising a valve body, a valve rod, a handle, an anti-skid sleeve, a threaded hole A, a threaded hole B and a fixing bolt, the valve body is provided with the valve rod at the upper end for controlling the opening and closing of the valve, the handle is sleeved on the upper end of the valve rod, the anti-skid sleeve is fixedly connected to the tail end of the handle, the threaded hole A is formed in the upper end of the valve rod, the threaded hole B is formed in the upper end of the handle, and the fixing bolt for fixing the valve rod and the handle is threadedly connected to the inner side of the threaded hole A and the threaded hole B.

[0007] Preferably, the valve rod and the handle of the valve body are directly fixed by the hexagonal fixing bolt, when the valve rod is exposed for a long time, the top of the valve rod is also firmly attached to the handle, which will not cause the phenomenon that the handle is not firmly fixed due to the height of the valve rod and the uppermost edge of the handle, the handle is sleeved on the valve rod, the handle is fixed on the valve rod by the hexagonal bolt, the anti-skid sleeve made of plastic material is directly sleeved on the tail of the handle, the handle is fixed on the valve rod, and the valve is opened and closed by moving the handle to drive the valve rod to rotate.

[0008] As preferred, the handle comprises a round cap and a long rod; the right end of the round cap is provided with the long rod; the round cap and the long rod are integrally formed.

[0009] As preferred, the inner side clamping groove of the round cap matches the outer contour shape of the valve rod.

[0010] As preferred, the anti-skid sleeve adopts rubber material.

[0011] As preferred, the thread hole A and the thread hole B have the same hole diameter; the thread hole A is an upper opening hole; and the thread hole B is a through hole.

[0012] As preferred, the fixing bolt adopts a hexagonal head bolt.

[0013] The utility model discloses a handle and valve rod are integrally formed, and the handle is fixed on the valve rod through the hexagonal bolt, and the handle is fixed on the valve rod through the hexagonal bolt.

[0014] The utility model discloses a handle and valve rod are integrally formed, and the handle is fixed on the valve rod through the hexagonal bolt, and the handle is fixed on the valve rod through the hexagonal bolt. BRIEF DESCRIPTION OF DRAWINGS
