Abstract
The utility model discloses a ball valve with a lock, which comprises a valve body and a handle used for controlling opening and closing of the ball valve, wherein two bumps are arranged on the outer wall of the shell of the valve body; the positions of the two bumps are respectively consistent to the positions when the handle is totally opened or closed; the handle is provided with a latch which can slide longitudinally along the handle at the side close to the bumps; the front end of the latch extends toward the bumps; a notch which can be meshed with the bumps is arranged at the front end of the latch; the handle is also provided with a longitudinal chute; a locking mechanism used for locking or unlocking the latch is arranged on the chute in a penetrating way; the locking mechanism is a milled screw arranged on the chute in a penetrating way; and a check ring used for limiting the milled screw from loosing is arranged at the lower end of the milled screw. Under a condition of non-manual unlocking, the handle can not rotate due to other factors so as to further prevent the valve from being opened or closed abnormally; and when the handle does not need to be rotated, the present working status of the handle is locked; and the ball valve with the lock has simple structure.
Description
Technical field
The utility model relates to ball valve.
Background technique
At present, Chang Yong ball valve mainly is made up of valve body, valve seat, spheroid, valve rod, handle.Working principle is to apply certain torque and pass to spheroid in valve rod upper end with handle, makes its half-twist, the through hole of spheroid then with valve channel central lines or vertical, ball valve has just been finished the action of standard-sized sheet or complete shut-down.But, in reality is used,, cause the improper keying of valve, thereby produce the unnecessary wasting of resources or certain potential safety hazard because some artificial or other factor tends to touch handle under unnecessary situation.China national Department of Intellectual Property discloses a kind of lockable ball valve on December 7th, 2005, and the patent No. is 200410069419.9, and it is made as folding structure with handle, and handle turnover back locks by latch fitting and locking mechanism with valve body.Its structure is complicated, and handle overturns when operation easily owing to be the turnover structure.
The model utility content
Technical problem to be solved in the utility model just provides a kind of Ball Valve With Lock, and its novelty simple in structure can manually be pinned the required working state of valve after finishing normal keying.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: Ball Valve With Lock, comprise the handle that valve body and control ball valve open and close, it is characterized in that: described valve shell outer wall is provided with two projections, the position of described two projections is in complete opening with handle respectively or the position consistency when closing, being provided with one by projection one side on the described handle can be along the snap close of handle longitudinal sliding motion, the snap close front end extends to described projection direction, the snap close front end be provided with can with a recess of described projection engagement, also be provided with a chute longitudinally on the described handle, be coated with a locking framework that is used to lock or unclamp described snap close on the described chute.
Preferably, two projections on the described valve shell are arranged on the below of handle, and described snap close is located at the downside of handle.
Preferably, described handle is provided with the longitudinal spacing chute of restriction snap close deflection.
Preferably, described locking framework is the knurled screw that is located on the chute.Knurled screw is snap close fixedly, prevents that snap close is free to slide.
Improved, described knurled screw lower end also is provided with the back-up ring that the restriction knurled screw is deviate from.
The utility model moves on snap close owing to adopt technique scheme, and then handle can freely rotate, and when ball valve was in complete opening or closes, control lock was detained and moved, and that projection that its lower end recess is just corresponding with its lower position cooperates, and handle is locked.So under non-artificial situation of unblanking, can not produce the improper keying that the handle rotation causes valve because of other factors.The utility model can pin handle work at present state when not needing handle with sleeve, simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is embodiment's one structural representation one of the utility model Ball Valve With Lock;
Fig. 2 is embodiment's two structural representations two of the utility model Ball Valve With Lock.
Embodiment
As shown in Figure 1, be the utility model Ball Valve With Lock embodiment one, comprise the handle 1 that valve body and control ball valve open and close, described valve shell outer wall 2 is provided with two projections 21, the position of described two projections 21 is in complete opening with handle respectively or the position consistency when closing, being provided with one by projection 21 1 sides on the described handle 1 can be along the snap close 3 of handle longitudinal sliding motion, the snap close front end extends to described projection direction, the snap close front end be provided with can with a recess 31 of described projection engagement, also be provided with a chute 11 longitudinally on the described handle, be coated with a locking framework that is used to lock or unclamp described snap close on the described chute, also be provided with the longitudinal spacing chute 12 of restriction snap close deflection on the described handle, two projections described in the present embodiment on the valve shell are arranged on the below of handle, described snap close is located at the downside of handle, described locking framework is the knurled screw 4 that is located on the chute, and described knurled screw lower end also is provided with the back-up ring 5 that the restriction knurled screw is deviate from.
Fig. 2 is the simple and easy structure that is provided with of another kind of the present utility model, is not to be provided with back-up ring and longitudinal spacing chute with embodiment's one difference.
Certainly, the projection on the utility model ball valve shell outer wall also can be arranged on the handle top, and the sliding shackle correspondence is arranged on the top, and locking framework can be located at the handle upside, also can be located at downside.Cooperating structure form between described sliding shackle and chute can be varied, is not limited to the described concrete structure of the utility model.
