Abstract
The utility model relates to a locking device for a valve, which can be arranged on a valve body. The utility model is composed of a locking body which is combined by separated bodies, a fastening lock nut and an outer sleeve of the locking body. An opening circlip is arranged in an annular groove on the inner wall of the fastening lock nut, and is matched with a circlip slot on the locking body. A valve rod part of the valve body is clamped or covered by the locking body, the fastening lock nut is fastened on the locking body, and the valve can be locked. Thus, the purpose that the opening state of the valve is locked is obtained. The locking device can solve the locking problem of the valve, and can prevent that the locked valve is optionally opened by other persons. The utility model has the advantages of convenient and durable locking operation, reliable and safe locking, etc.
Description
The utility model relates to a kind of valve locking device, and this locking device especially is fit to locking and often opens or normal closed gate.
Existing valve only need carry out the adjusting and the control of flow quantity, and valve can at will be regulated, opens or be closed, and need not set the valve locking device.But the valve flow quantity that has in case there is the people at will to change, is opened or throttle down after setting mistakenly, brings undue harm will for production or environment, even also can cause human casualty accident.Therefore, the valve of more existing application of special occasions should install valve Dingan County full protection device additional.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of valve locking device is provided, and this device can lock the valve of setting.
The utility model above-mentioned purpose can realize by following technical measures.
A kind of valve locking device, this locking device can be installed on the valve body, it is characterized in that said locking device is made up of split synthetic sealed body and fastening lock nut, be provided with uncovered jump ring in the above-mentioned fastening lock nut inwall annular groove, match with the jump ring groove on the sealed external wall, be buckled on the sealed body and be used for Locked valve.Above-mentioned sealed body can be designed to two body composite structures as required, or trisome, limbs composite structure, and can block or encase the structure shape of the valve stem part of valve body according to sealed body, and is provided with Fixing clamp-seat on sealed body inwall.This Fixing clamp-seat is mainly used in the chucking valve body, prevents that locking device breaks away from valve body.
Increase sealed intensity for protection lock is fit, the sealed external wall of above-mentioned locking device preferably is set with a sealed external cover.
Valve locking device structure provided by the utility model is simple, and Locked valve locks reliable, convenience preferably, can prevent people's opening/shutting valve mistakenly effectively.In addition, this locking device can also prevent the valve corrosion effectively, particularly installs some lubricant oil additional in sealed body inwall, more can help the Protective valve door.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Among the figure: 1. valve body 2. sealed external cover 3. sealed body 4. decks 5. jump ring grooves 6. lock nuts
7. jump ring
The deck 4 that sealed body 3 among the figure and inwall thereof are set up, sealed external cover 2, lock nut 6, can come out with metal casting, process jump ring groove 5 with the upper end portion outer wall that is machined in sealed body 3 then, on the inwall of lock nut 6, process annular groove, and in this annular groove the uncovered jump ring 7 of fit on.During use, will block the valve stem part of (or encasing) valve body 1 by the bottom of the synthetic sealed body 3 of two bodies earlier, put sealed external cover 2, lock nut 6 will be buckled in sealed body 3 upper end portions, the jump ring 7 in the lock nut 6 is stuck in the jump ring groove 5.Lock nut 6 can be used as disposable easily damaged parts.If open or pass wall valve, as long as pressing from both sides broken lock nut 6 with special-purpose pliers just can remove locking device, and then regulating valve.
