Abstract
The utility model provides a spring shaft type locking valve which comprises a valve body and a locking device which is arranged on the valve body. The locking device is composed of a locking cap, a spring and a locking shaft. The spring and the locking shaft are orderly arranged on a locking hole of a valve rod of the valve body. A shaft line of the locking hole is perpendicular to the shaft line of the valve rod. The spring is positioned on the bottom part of the locking hole. One end of the locking shaft is extended out of the locking hole. The inner wall of the locking cap is provided with an annular groove, and the locking shaft slides in the annular groove. The spring shaft type locking valve has the advantages of simple structure, convenient use and high reliability. The spring shaft type locking valve can radically stop the phenomenon that a water cutting-off user illegally opens a control valve so that the smooth completion of the operation of heating is guaranteed.
Description
The utility model relates to a kind of valve, particularly a kind of bullet shaft type locking valve that is suitable for the heating system use.
At present, heating charging is the hard nut to crack of puzzlement China various places heating unit always, some illegal users often refuse to pay relevant heating cost with all excuses, have seriously influenced the economic benefits of heating department, thereby have made heating work normally to carry out.At this problem, though some unit takes to add the cartridge control valve measure entry of refusing to pay the user is controlled on house branch, but since control valve itself effectively self-locking prevent that illegal secondary from opening, therefore it also performs practically no function in use for some time, can not fundamentally address the above problem.
The purpose of this utility model provides a kind of simple in structure, and is easy to use, the bullet shaft type locking valve that reliability is high, and it can overcome the generation of the problems referred to above effectively, the generation of phenomenon thereby the illegal opening controlling valve of user of fundamentally stopping to cut off the water heats again.
The purpose of this utility model is achieved in that it comprises valve body, it is characterized in that: locking closure is installed on the valve body, locking closure is made up of lock nut, spring and lock shaft, spring and lock shaft are placed in the lockhole at valve body stem position place successively, the lockhole axis is vertical with valve rod axis, and spring is positioned at the bottom of lockhole, and an end of lock shaft stretches out lockhole, the inwall of lock nut offers annular groove, and lock shaft is slidably in it.
When the heating user refuses to pay the fees, the valve rod of at first adjusting valve body is closed it, then lock shaft and spring are pressed in the lockhole on the valve body, put lock nut, lock shaft snaps in the annular groove of lock nut inwall automatically under the elastic force effect of spring, thereby limited moving up and down of lock nut, and then controlled other people unlatching, finally reached the purpose of locking the valve body valve rod; During unlatching, dedicated hydraulic is opened pincers and is opened, and non-special tool can not be opened by force, otherwise can cause the damage of product, even water pouring.
The utility model is by installing the locking closure of being made up of lock nut, spring and lock shaft additional on original valve body, the user opens under the situation of no special tool by force, can directly cause the damage of product, even water pouring, the secondary of having stopped effectively after ball valve is closed is illegally opened the generation of phenomenon, so can fundamentally guarantee normally carrying out in order of the work of heating.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the utility model comprises valve body 4, valve body 4 can be the valve body 4 of ball valve body or other any switch valves, it is that example describes that present embodiment adopts ball valve body, valve body 4 upper valve rods 5 positions are equipped with locking closure, locking closure is made up of lock nut 1, spring 2 and lock shaft 3, spring 2 and lock shaft 3 are placed in the lockhole of valve body 4 valve rods 5 positions successively, lockhole axis and valve rod 5 axis normal, spring 2 is positioned at the bottom of lockhole, one end of lock shaft 3 stretches out lockhole, and the inwall of lock nut 3 offers annular groove 7, and lock shaft 3 is slidably in it.
Among the figure 6 is the spheroid of ball valve body, and spheroid 6 and valve rod 5 fixing interlocks are used to realize closing of valve body.
Claims (2)
