Abstract
The utility model relates to a lock type valve which is composed of a valve body, a valve cover, a valve rod, and a sealing screw nut. The utility model is characterized in that the upper part of the valve rod has a prism-shaped structure; holes are arranged on the sealing screw nut, and a corresponding lock bar on which a groove is arranged is also arranged on the sealing screw nut; a lock body is inlaid in the sealing screw nut; a lock tongue and the groove in the lock bar compensate each other. The utility model has the advantages the structure is simple, and the functions flow control and burglar prevention can be provided. The utility model can be used for various valves.
Description
The utility model relates to a kind of valve, especially a kind of locking-type valve with lock.
Valve is widely used in every field, but manyly local need control stream, when antitheft, general valve just can not meet the demands, Hu Wai pipeline valve for example, water tap of residential belt or the like causes the waste of various resources more serious owing to not locking.Common throttling measure is that a special box is installed on valve, and adds and lock, this Valve with lock, can not accomplish simple and practical, open convenient.
The purpose of this utility model is to provide a kind of unlatching to lock locking-type valve and that valve is combined as a whole easily.
For achieving the above object, provide technological scheme as follows: the locking-type valve is made up of valve body, valve gap, valve rod and sealing nut, the part that particularly top of valve rod is positioned in the middle of the sealing nut is made prism, on sealing nut, have the hole, and be furnished with and the corresponding locking bolt in hole, groove is arranged on the locking bolt, locking bolt contacts with prismatic surface on the valve rod, also stud with lock body in sealing nut, the groove on dead bolt and the locking bolt compensates mutually.
The method that this locking-type valve has adopted the locking valve rod to change distance realizes the control to valve, has simple and practically, opens characteristics easily, can play control stream, energy-conservation effect.
Below in conjunction with embodiment's accompanying drawing the application is described in further detail.
Fig. 1 is the profile schematic representation of locking-type valve.
Fig. 2 is the internal structure schematic representation of sealing nut and valve rod attachment portion on the locking-type valve.
Among Fig. 1, the locking-type valve is by valve body 1, valve gap 2, valve rod 3, sealing nut 4 is formed, and the part that the top that can see valve rod 3 in Fig. 2 is positioned in the middle of the sealing nut is made into prism 5, in sealing nut porose 6, about the endoporus of hole 6 sealed nuts has been divided into two sections, one section is through hole, and one section is non through hole, locking bolt 7 matches with hole 6, locking bolt 7 can be a prism, also can be cylindrical body, just contacts with a face of prism 5 on the valve rod in locking bolt 7 patchholes 6, on locking bolt 7 fluted 8, lock body 10 is set in the sealing nut 4, and the groove 8 on dead bolt 9 and the locking bolt 7 compensates mutually, is just locked by dead bolt 9 after locking bolt 7 enters in the hole 6 fully, because the plane contact of locking bolt 7 and prism 5, the distance at locking bolt 7 and valve rod center makes valve rod 3 not rotate less than the commentaries on classics distance of valve rod 3, thereby realizes the control to valve.In order to lock valve rod better, the rotation direction of valve rod can be arranged to opposite direction with the rotation direction of sealing nut.
