Abstract

The utility model discloses a valve, particularly a ball valve with a lock. The utility model is composed of a valve body (4), a water inlet (5), a water outlet (6), a valve core, a valve rod (1) and a lockset, wherein, the lockset is composed of a lock body (3), a lock core (2) and a group of ball lock springs. The lock body (3) is sheathed on the valve rod (1), and the lower part of the lock body (3) is connected with a valve rod sleeve (4') by screw threads. The lock core (2) is partly intersected with the valve rod (1). Two grooves which are arranged on the intersecting position of the valve rod are engaged with the lock core, and are perpendicular each other. A platform is arranged on the lock core (2) along an axis direction. The utility model has the advantages of reasonable design and simple structure, and the ball valve can be conveniently and safely locked under the opening state and the closing state.

Description

Ball Valve With Lock

The utility model relates to a kind of valve, particularly a kind of ball valve.

Ball valve is simple in structure with it, good seal is widely used in the various piping erection, especially water supply pipe, tap water has brought a lot of facilities for people's life, but collecting of tap water water rate is a pretty troublesome problem always in the real life, always there are some users to be reluctant to hand over water rate, can only stop his water as water utility, stop individual user's water only way in the past and plucked water meter exactly, it is cumbersome plucking water meter one, after if the user pays off debt in addition, water meter must be loaded onto, so frequent dismounting, the water meter interface is easy to damage.Another situation is for the pipeline of normal use, it wherein the opening and closing of valve all be autotelic, do not allow other people at will to touch, but also do not have what way effectively to address these problems at present.

It is a kind of reasonable in design, simple in structure that the purpose of this utility model will provide exactly, at the Ball Valve With Lock of opening or closed condition can both conveniently lock.

For achieving the above object, the utility model adopts technological scheme as described below: Ball Valve With Lock is made up of valve body, water intake, water outlet, spool, valve rod and lockset, lockset is made up of lock body, lock core and one group of pellet shot from a slingshot snap, lock body sheath is on valve rod, and the bottom of lock body is by being threaded on the valve stem casing with the valve body one, and with pin lock body and valve body is connected as a single entity.Lock core is vertical each other with valve rod and part is crossing, the groove that is meshed with lock core is arranged on the valve rod of this intersection location, there is a platform axis aspect, lock core upper edge, when with key rotation lock core during with the groove of the platform on the lock core on valve rod, valve rod is not stopped, can open and close flexibly, as need ball valve is pinned, as long as rotational lock core, the part of lock core is engaged in the groove of valve rod, valve rod is subjected to just stopping of lock core and can not have rotated.If have two grooves on the valve rod, and two grooves are perpendicular to one another, and open or closed condition all can be locked at ball valve so.

Adopt the utility model of said structure to change under the little situation at former ball-valve structure, realized the function that can both lock under the opening and closing state, the pipeline that this ball valve is installed can be controlled break-make easily

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a sectional structure schematic representation of the present utility model.

Fig. 3 is a plan view of the present utility model.

Fig. 4 is that the A-A of Fig. 3 is to sectional view.

With reference to Fig. 1, Fig. 2.Ball Valve With Lock is made up of valve body 4, water intake 5, water outlet 6, spool, valve rod 1 and lockset.Lockset is made up of lock body 3, lock core 2 and one group of pellet shot from a slingshot snap 10.Lock body 3 is enclosed within on the valve rod 1, its underpart by be threaded in the valve stem casing 4 of valve body 4 one ' on, lock core 2 is vertical each other with valve rod 1 and part is crossing, the groove 7 that is meshed with lock core 2 is arranged on the valve rod of intersection location, 8, groove 7 and groove 8 are perpendicular to one another, lock core 2 upper edge axial directions have a platform 9, when with key rotation lock core with the groove of platform 9 on the valve rod, this moment, lockset was an opening state, and valve rod is not stopped, can rotate flexibly, when needing to pin ball valve, rotational lock core is engaged on the part of lock core in the groove 7 or 8 of valve rod, and valve rod 1 was subjected to just stopping of lock core 2 and can not rotates this moment.The groove 7,8 that is perpendicular to one another on the valve rod 1 is the opening and closing state of corresponding ball valve respectively, therefore ball valve can both be locked under this two states.

When ball valve is locked, the teeth of key face pellet shot from a slingshot snap 10, this moment, key can conveniently be pulled up, also can conveniently pull up when lockset is opening state in order to make key, increased by one group of pellet shot from a slingshot snap 11 on the lock body 3 again, platform 9 on angle between the pellet shot from a slingshot snap 10,11 and the lock core and the angle between valve rod axis equate, when the groove of the platform on the lock core 9 on valve rod, the teeth of key are just in time aimed at pellet shot from a slingshot snap 11, key can be pulled up, and the utility model of this moment is an ordinary ball valve.

With reference to Fig. 3, Fig. 4.Be inserted with square cotter 12 on the lock body 3, valve stem casing 4 ' on cotter way 13 is arranged, the lower end of square cotter 12 is inserted in the cotter way 13, with lock body 3 and valve stem casing 4 ' be connected as a single entity.Square cotter 12 intersects with lock core 2 parts, the groove that is meshed with lock core is arranged on the square cotter, when ball valve is locked, groove on the square cotter is stopped and can not be pulled out that this moment, square cotter was connected as a single entity lock body and valve body by lock core, lock body can not be backed out, when lockset is in opening state, square cotter 12 can be pulled out, and lock body can be backed out, and is convenient to the maintenance of lock body and valve.

In addition, enter the lockhole of lock core, can on the front panel of lock body, install a dust cover additional in order to prevent earth and foreign material.
