The utility model discloses a valve, spanner, its structural feature is that the case top of valve has the flat body corresponding with the spanner recess, has the lock core in the valve body of the valve of flat body top, has the lockplate corresponding with the groove on the valve body on the eccentric shaft of lock core below. The utility model has the characteristics of convenient to use, theftproof nature is strong etc.

Description

Locking-valve

The utility model relates to the improvement of valve arrangement.

Present valve does not all have locking framework, thus heating not the payor also can not get control, seriously restrict the development of heating cause.

The purpose of this utility model just provides a kind of locking-valve easy to use, that have locking framework.

The purpose of this utility model is achieved in that the utility model comprises valve, spanner, its structure outline is that the spool top of valve has and the corresponding flat body of spanner groove, have lock core in the valve body of the valve of flat body top, have on the eccentric shaft of lock core below with valve body on the corresponding lockplate of groove.

Major advantage of the present utility model:

1, easy to use:

When desiring switch the utility model valve, at first lock core is taken out, stir spool with spanner then and can carry out and open or close action, it is extremely convenient to use;

2, anti-theft is strong:

Valve of the present utility model top is provided with lock core, do not take out lock core and just can not make the spool action, so the safe antitheft of this valve is good.

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

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the sectional view of the B-B of Fig. 1;

Fig. 4 is the schematic representation of the structure of spanner;

Fig. 5 is that Fig. 4 is a sectional view.

Below in conjunction with accompanying drawing concrete structure of the present utility model is done nearly step explanation:

The utility model comprises valve 1, spanner 9, and spool 2 tops of valve 1 have and spanner 9 grooves 10 corresponding flat bodies 3, have lock core 6 in the valve body 7 of the valve 1 of flat body 3 tops, have on the eccentric shaft 5 of lock core 6 belows with valve body 7 on groove 8 corresponding lockplates 4.

Narrate a course of action of the present utility model below:

Desire is opened or when closing the utility model valve, at first by key rotation lock core 6, lock core 6 drives lockplate 4 by eccentric shaft 5 and rotates, until arriving groove 8 not in the taking-up that limits lock core 6, after taking out lock core 6 (lock core that general does not get down from horse), the groove 10 of spanner 9 can be inserted into 3 ones of the flat bodies of spool 2, rotational valve core 2 reaches and opens or the purpose of cut-off valve.

Claims (1)

1, locking-valve comprises valve 1, spanner 9, spool 2 tops that it is characterized in that valve 1 have and spanner 9 grooves 10 corresponding flat bodies 3, have lock core 6 in the valve body 7 of the valve 1 of flat body 3 tops, have on the eccentric shaft 5 of lock core 6 belows with valve body 7 on groove 8 corresponding lockplates 4.
