The beneficial effects of the utility model reside in that: the clamp of the embodiment of the disclosure encloses on the valve body of pressure reducing valve, and one end pressure of each puller bolt connected on the clamp through the bracing piece can support pressure reducing valve adjustment handle, thereby restricts the motion of pressure reducing valve adjustment handle, realizes the locking to pressure reducing valve adjustment handle, can prevent pressure reducing valve adjustment handle's maloperation effectively to effectively ensure system safety, economy, operation reliably.
Drawings
FIG. 1 is a spring diaphragm pressure relief valve adjustment handle positioning locking device shown according to an exemplary embodiment.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a spring diaphragm pressure relief valve adjustment handle positioning locking device shown according to an exemplary embodiment. As shown in fig. 1, the positioning and locking device for the adjusting handle of the spring diaphragm type pressure reducing valve can comprise: clamp 1, a plurality of jack bolts 3 and a plurality of bracing piece 4.
As an example of this embodiment, the clamp 1 may surround a valve body of a pressure reducing valve; for example, the clamp 1 may include a first fastening half 7 and a second fastening half 8, where the first fastening half 7 and the second fastening half 8 may be connected by a locking structure 6 (for example, the locking structure 6 is a locking bolt or a buckle, and the like, and the disclosed embodiment does not limit the type of the locking structure 6), so that the first fastening half 7 and the second fastening half 8 may tightly surround a valve body of the pressure reducing valve. In a possible implementation manner, the hoop of the clamp 1 may also be an elastic sheet, two ends of the elastic sheet may have fastening structures that can be fastened to each other, the elastic sheet may surround the valve body, and the fastening structures at two ends of the elastic sheet are fastened to each other, it should be noted that an applicable clamp 1 structure may be selected according to actual conditions, and the structure of the clamp 1 is not limited in the embodiment of the present disclosure.
One end of each support rod 4 can be connected to a hoop of the hoop 1, each support rod 4 can be perpendicular to the hoop, and each support rod 4 is positioned on the same side of the hoop; the other end of every bracing piece 4 can have the screw hole, connects a puller bolt 3 in this screw hole soon, and the one end of each puller bolt 3 can be towards the center of clamp 1, and maintenance person can be through rotating each puller bolt 3 for the one end of each puller bolt 3 moves towards the center of clamp 1, and presses the adjustment handle who supports the relief valve.
The clamp of the embodiment of the disclosure encloses on the valve body of pressure reducing valve, and one end pressure of each puller bolt connected on the clamp through the bracing piece can support pressure reducing valve adjustment handle, thereby restricts the motion of pressure reducing valve adjustment handle, realizes the locking to pressure reducing valve adjustment handle, can prevent pressure reducing valve adjustment handle's maloperation effectively to effectively ensure system safety, economy, operation reliably.
In one possible implementation, the locking structure may include a split bolt and a split nut, whereby a tighter locking may be achieved
In a possible implementation manner, the hoop may have a threaded hole formed along the axial direction, and an outer surface of one end of each support rod 4 may have a thread, so that each support rod 4 can be screwed into one threaded hole. Maintenance personnel can rotate each bracing piece 4 for bracing piece 4 can move for the hoop, can drive corresponding tightening rod from this and move for the hoop. Therefore, the distance between the tightening rod and the hoop can be adjusted, so that the tightening rod can flexibly lock the pressure reducing valve adjusting handles of different types and sizes. In one possible implementation, each support rod 4 may be fixed in the corresponding threaded hole by a locking nut 5, for example, the support rod 4 may be rotated, the tightening rod adjusted to a suitable height, and the locking nut 5 tightened to fix the support rod.
