Abstract

The utility model relates to a lock type locking valve which can effectively manage the opening and the closing of the valve. The utility model is composed of a valve body and a lock sleeve. A valve rod is arranged in an inner cavity of the valve body. The lock sleeve is sheathed on the valve body. A lock is arranged in an inner hole of the lock sleeve. Rectangular grooves with the same width are respectively arranged on a lock core and a lock seat. The lock core and the lock seat can mutually rotate, and the rotating degree of the lock core and the lock seat is larger than 35 DEG. A locking pin is arranged on the inner hole of the lock sleeve, and is clamped in each of the rectangular grooves of the lock core. The utility model has the advantages of simple structure and easy realization, and is especially suitable for the valve in a heating system.

Description

The locking-type locking valve

The utility model relates to valve technology field, and exactly it is a kind of locking-type locking valve of providing convenience for management valve.

At present, the valve that industries such as chemical industry, hot-water heating are used can be opened or close mostly with general utility tools such as hand or spanners, should not carry out management.And in unified heating system, be that the unit heating is a developing direction with the family, after promptly the user paid heating cost, the valve open that the professional workforce is led to this user with common conduit got final product.But anyone all can arbitrarily open existing valve, can't manage.

The purpose of this utility model provides a kind of locking-type locking valve, and it makes common people be difficult to open this valve, and after opening, the very easy discovery of administrative staff, the opening and closing of valve must be used key and special tool, thereby the switching of control valve effectively reaches the purpose of management.

The purpose of this utility model is achieved by the following scheme, it is made up of valve body and lock tube, it is characterized in that: valve rod (3) is contained in valve body (2) inner chamber, lock tube (1) is enclosed within on the valve body, and lock (4) is contained in lock tube (1) hole, lining, all has the rectangle groove of same width on lock core (7) and the lock (6), lock core (7) and lock (6) can rotate mutually, rotation angle is not less than 35 °, on lock tube (1) endoporus stop pin (5) is housed, and stop pin (5) is stuck in lock core (7) rectangle groove.Valve rod (3) upper end is flat or inside and outside hexagon or cross recess.

The utility model has the advantages that: this valve makes the management of valve become possibility with the arbitrarily opening and closing of non-special tool.The utility model double insurance must at first be unblanked during use, opens valve rod with special tool then, thereby good anti-theft effect.In addition, the utility model is simple in structure, realizes easily, is easy to promote.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

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

Fig. 6 is the worm's eye view of Fig. 5.

1 is that lock tube, 2 is that valve body, 3 is that valve rod, 4 is that lock, 5 is that stop pin, 6 is that lock tube, 7 is a lock core among the figure.

Embodiment 1:

The utility model is changed a social system on the basis of existing valve and is got final product, and possesses general machining equipment and just can produce.Get all the in the accompanying drawing that assembling gets final product with reference to accompanying drawing behind the part ready.During use, will lock to rotate with key the rectangle groove of lock core and lock is communicated, will lock taking-up after, again lock tube is taken off, with special tool valve rod is rotated, at this moment, valve opening then, locks lock again.Flat can be made in the valve rod upper end.

Embodiment 2: square or outer-hexagonal shape are made in the valve rod upper end, and all the other structures are identical with embodiment 1.

Embodiment 3: cross recess is made in the valve rod upper end, with the opening and closing of cruciate flower spiral shell cutter.The shape and size that it should be noted that valve rod upper end among the embodiment 1,2,3 should not made standard measure, should turn valve rod with conventional tool.

Claims

1, locking-type locking valve, it is made up of valve body and lock tube, it is characterized in that: valve rod (3) is contained in valve body (2) inner chamber, lock tube (1) is enclosed within on the valve body, and lock (4) is contained in lock tube (1) hole, lining, all has the rectangle groove of same width on lock core (7) and the lock (6), lock core (7) and lock (6) can rotate mutually, rotation angle is not less than 35 °, on lock tube (1) endoporus stop pin (5) is housed, and stop pin (5) is stuck in lock core (7) rectangle groove.
