Embodiment

In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing Illustrate specific embodiment of the present utility model.

As shown in Figure 1, 2, the valve locking device of the embodiment of the utility model one, including lid 10 and neck 20.Lid 10 are set on the valve body 1 of valve；Neck 20 is arranged on the side plate of the corresponding valve handle 2 of lid 10, is engaged handle 2 and is limited Handle 2 rotates folding on valve body 10.Valve includes manual ball valve.

Lid 10 may include cover plate 11 and several side plates 12 of connecting cover plate 11.Cover plate 11 is used to coordinate to enter in valve body 1 Mouth end or port of export periphery, several side plates 12 coordinate on the periphery of valve body 1, and opposing cover plates 11 extend to the direction of handle 2.Card The corresponding handle 2 of groove 20 is arranged on side plate 12.

Preferably, cover plate 11 entering on outgoing direction on valve body 1 positioned at valve, as valve body 1 entrance point or the port of export on. In the present embodiment, the remote of valve body 1 is set according to the situation of standard-sized sheet when parallel with the pipeline for connecting valve body 1 of handle 2, lid 10 On one end from the grip part of handle 2；Handle 2 is fastened in neck 20 by its tooth portion 3 that turns of cooperation on valve body 1.By right The engaging in 2 turns of tooth portions 3 of handle, limits the rotation space for turning tooth portion 3, so as to limit rotation of the handle 2 on valve body 1.

With reference to Fig. 2,3, cover plate 11 may include substrate 111, and substrate 111 is provided with through hole 112, and through hole 112, which is formed, to be coordinated The entrance point of valve body 1 or the resigning portion of port of export periphery.In addition, the size of through hole 112 is more than the periphery of the entrance point of valve body 1 or the port of export Size, facilitate movement of the cover plate 11 on the end.When cover plate 11 coordinates on the end of valve body 1, neck 20 engages handle 2, limitation Handle 2 rotates；When needing rotational handle 2, cover plate 11 is moved on the end of valve body 1, drives neck 20 to away from the side of handle 2 To movement, neck 20 is set to release the engaging to handle 2, so as to which handle 2 can rotate on valve body 1.

In the utility model, lid 10 can made of a steel disc integrative-structure, it is simple in construction, simple and cost is made It is low.Side plate 12 can opposing cover plates 11 be bent to form.Lid 10 is made using the steel disc with certain thickness such as 1.5mm, makes its tool There is the rotation that some strength can limit handle 2.

The peripheral shape that the peripheral shape of lid 10 corresponds to valve body 1 is set, and is such as in polygon or circle.

For convenience of dismounting of the lid 10 on valve, the cover plate 11 of lid 10 can be Open architecture.For example, through hole 112 Side plate 12 is extended on cover plate 11, is connected with neck 20, the opening of whole lid 10 can be formed.Opened and covered by opening Body 10, cover plate 11 can be coupled on valve body 1, by the aligned fit of neck 20 on handle 2.

Or through hole 112 extends to another side plate 12 on cover plate 11, and run through side plate 12, whole lid 10 can be formed Opening；Another side plate 12 and the side plate 12 where neck 20 are adjacent or relative.Lid 10 is opened by opening, can be by cover plate 11 are coupled on valve body 1, by the aligned fit of neck 20 on handle 2.

With reference to figure 1,2, the valve member of the embodiment of the utility model one, including valve and above-mentioned locking valve dress Put.

Wherein, the lid 10 of valve locking device is separably set on the valve body 1 of valve, the card of valve locking device Groove 20 separably engages handle 2, and limitation handle 2 rotates folding on valve body 1.

In the present embodiment, valve is manual ball valve, suitable in source gas line, as steam supply valve.

In valve member, by the setting of valve locking device, reach the purpose for preventing valve from being touched by mistake, while do not influence Field operator's urgent intervention and system equipment are normally run.

Valve locking device of the present utility model in use, rotational handle 1 make its with connect valve body 1 pipeline it is parallel after (valve wide open), lid 10 is linked on valve body 1, neck 20 is engaged into handle 2 is rotated with limiting handle 2, is protected in nuclear island The normal operation of supply is demonstrate,proved.After valve use, lid 10 is somewhat departed from into valve body 1, drives neck 20 to depart from handle 2, It is now that rotatable handles 2 make it perpendicular with pipeline, closes valve, it is simple to operate.

Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
