CN2222771Y - Valve lock - Google Patents

Abstract

The utility model discloses a valve lock which is an improved design on the basis of existing plug-in type bicycle locks. The end part of a U-shaped lock rod is bent to a right angle, and a blind hole used for containing a valve rod is arranged on a lock body. The valve rod enters the blind hole on the lock body to ensure that the lock rod is sheathed on a pipeline, and a valve can be locked when the lock body inserted in. The utility model has the advantages that facilities in original pipelines are not changed, and one lock can be used at many places for many times. In addition, the valve lock also has the advantages of simple structure, easy assembly and disassembly, favorable universality, low cost, simple maintenance and long service life.

Description

A kind of valve lock

The utility model belongs to a kind of locking device, particularly a kind of valve lock that the valve switch state is locked.

Along with The development in society and economy, produce widely, sphere of life, because to the conveying of most of gas and liquid, the management control of supply and the needs of metering, the valve opening and closing state in the transfer pipeline has proposed the requirement that is locked.

At present, the method that has is that for the open and-shut mode of Locked valve, people adopt the wooden case or the iron case of the band door of valve outer setting on pipeline, adorn lock on chamber door, guarantee the valve state sealing.But this mode is subjected to fixing local space condition restriction, integral installation difficulty, or at all can't install in many occasions, and it is limited that back self intensity, life-span is installed.So this mode adopts not general.Remove this, also do not have a kind of desirable valve locking device at present, can take into account the locking of existing valve in pipeline simultaneously again.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the arbitrary state of valve opening and closing in the existing pipeline is locked, and a kind of valve lock is provided.

The utility model is to realize like this.

The utility model is the improvement design of existing plug-in type bicycle lock, the end that is about to its H type locking bar curves the right angle, be processed with the blind hole of holding valve rod on the lock body, when the arbitrary state of needs Locked valve, earlier valve is arranged on and needs state, unload rotation hand wheel on the lower valve (or handle, wrench) then, make valve rod enter blind hole on the lock body, utilize the relation of being fixedly connected of pipeline and valve, locking bar is enclosed within on the pipeline, the locking of insertion lock body is closed a certain state of valve opening and closing effectively, i.e. locking realizes.

Advantage of the present utility model is:

1, do not change arbitrary facility in original pipeline, thereby do not have the fault that may occur after recondition expense and the repacking.

2, simple in structure, easy to loading and unloading, when valve must lock, only need unload rotation hand wheel and valve stem tip screw earlier, again the valve locking is got final product.When locking must be removed, this lock is taken and can be taken away.

3, open flexibly easily, versatility is good, and interchangeability is good, and it is cheap to make use cost, and maintenance technique is simple and easy.Reason is; The utility model adopts ripe bicycle lock technology, but and one the lock many places repeatedly use.

4, the life-span long, the flexibility of the utility model installation site, can effectively prevent the lock body part by gas, liquid in the pipeline in the burn into oxidation of valve place seepage institute, the general life-span is identical with ordinary bicycle.

Provide the utility model embodiment below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

As shown in the figure, the utility model has a lock body 1, the structural similarity of lock body 1 and existing bicycle plug-in type lock body, unique difference is to have processed a blind hole on lock body 1, is used to hold valve rod, and 2 is locking bar, the difference of it and plug-in type bicycle lock U-shape sword iron is that its end curves the right angle, also have key 3 on the lock body 1, utilize key 3 lock can be opened, lock body 1 is separated with locking bar 2.

Claims (1)

1, a kind of valve lock comprises lock body (1), and locking bar (2) is characterized in that, the end of locking bar (2) curves the right angle, and lock body is processed with the blind hole of holding valve rod on (1).
