Description
Technical Field
The utility model relates to a valve field especially relates to a locking device on butterfly valve.
Background
A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The butterfly valve is mainly connected with the pipeline through the flange plate, the flange plate is fixed by screwing in the bolt and the nut, but the nut is easy to loosen along with long-time use, so that the whole looseness is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a locking device on butterfly valve.
The utility model discloses a realize through following technical scheme: the utility model provides a locking device on butterfly valve, includes the butterfly valve, a set of relative screw hole has been seted up respectively at the both ends of butterfly valve, screw hole female connection has the bolt, threaded connection has the nut on the bolt, be equipped with locking Assembly between the butterfly valve both ends screw hole, locking Assembly includes the check lock lever, the inside of check lock lever is equipped with horizontal first through-hole, be equipped with locking screw thread on the inner wall of first through-hole, threaded connection has the compression bar respectively at the both ends of first through-hole, the inside of compression bar is equipped with the second through-hole, be equipped with on the inner wall of second through-hole and compress tightly the screw thread, the second through-hole is through compressing tightly screw thread.
The utility model has the advantages that: like this when bolt and nut twist put into the check lock pole between two relative bolts after, rotate the compression bar in the check lock pole this moment and make the second through-hole on the compression bar twist on the bolt and gland nut, the check lock pole can be fixed between two bolts this moment, because be threaded connection between compression bar and the check lock pole together, so can not take place relative motion between compression bar and the check lock pole, like this alright through compression bar gland nut, the nut has been prevented from taking place not hard up, the stability of butterfly valve and pipe connection has further been guaranteed.
Drawings
Fig. 1 is a schematic front view of the present invention;
in the figure: 1. a butterfly valve; 2. a bolt; 3. a nut; 4. a locking lever; 5. a first through hole; 6. a hold down bar; 7. a second via.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a butterfly valve 1, a set of relative screw hole has been seted up respectively at butterfly valve 1's both ends, threaded hole female connection has bolt 2, threaded connection has nut 3 on bolt 2, be equipped with locking Assembly between the 1 both ends screw hole of butterfly valve, locking Assembly includes check lock lever 4, the inside of check lock lever 4 is equipped with horizontal first through-hole 5, be equipped with locking thread on first through-hole 5's the inner wall, threaded connection has compressing tightly pole 6 respectively at first through-hole 5's both ends, compressing tightly the inside of pole 6 and being equipped with second through-hole 7, be equipped with compressing tightly screw on the inner wall of second through-hole 7, second through-hole 7 is through compressing tightly threaded connection on bolt 2.
The utility model has the advantages that: like this put into the check lock 4 between bolt 2 and nut 3 wrong back relative two bolt 2, rotate the compress tightly pole 6 in the check lock 4 this moment and make the second through-hole 7 on the compress tightly pole 6 twist bolt 2 and gland nut 3, check lock 4 can be fixed between two bolts 2 this moment, because be threaded connection between compress tightly pole 6 and the check lock 4, so can not take place relative motion between compress tightly pole 6 and the check lock 4, like this alright compress tightly nut 3 through compress tightly pole 6, the nut 3 has been prevented from taking place not hard up, the stability of butterfly valve 1 and pipe connection has further been guaranteed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
