Detailed Description
The present application is described in further detail below in conjunction with figures 1-3.
Referring to fig. 1, the prior art shut-off valve comprises a valve body 21 embedded in a pipe 1, a valve seat 22 threadedly connected to the valve body 21, a valve stem 25, and a hand wheel 24, the hand wheel 24 being at an end of the valve stem 25 remote from the valve seat 22. A sealing gasket 23 is arranged between the valve seat 22 and the valve body 21, the sealing gasket 23 is made of PTFE material, a certain compression amount is achieved, and the valve seat 22 is screwed and sealed through the sealing gasket 23. The gasket 23 is in a compressed state when the relevant staff member makes the valve seat 22 and the valve body 21 achieve a tight seal by the gasket 23. However, as the service life increases, the gasket 23 will be permanently deformed to a certain extent, and the anti-unscrewing torque between the valve seat 22 and the valve body 21 will be reduced, so that when the valve body 21 and the valve seat 22 are in a screwed state, the valve seat 22 will be relatively easy to be rotated by an external force, and the valve body 21 and the valve seat 22 will be in a unscrewed state, thereby easily causing the problem of unexpected water leakage.
The embodiment of the application discloses a stop valve locking mechanism applied to a pipeline 1.
Referring to fig. 2, a shut-off valve locking mechanism applied to a pipe 1 includes a first coupling member 3 and a second coupling member 4, the first coupling member 3 being fixedly installed on a valve body 21 and being located at a side of the valve body 21 near a valve seat 22. The second connector 4 is fixedly mounted on the valve seat 22, and the second connector 4 is disposed adjacent to the first connector 3, and the first connector 3 is detachably mounted on the second connector 4. After the valve seat 22 and the valve body 21 are tightly screwed and sealed through the gasket 7, related personnel install the first connecting piece 3 on the second connecting piece 4, so that the valve seat 22 and the valve body 21 can be kept in a screwed state as far as possible, and the water leakage problem caused by accidental rotation of the valve seat 22 is avoided.
Referring to fig. 2 and 3, in this embodiment, the first connector 3 and the second connector 4 are each in the shape of a circular ring as a whole. The second connecting piece 4 is detachably mounted on the first connecting piece 3 through a clamping structure, a thread structure or a magnetic attraction structure, and in this embodiment, the thread structure is adopted. Six first connecting holes are formed in the first connecting piece 3 at equal intervals along the circumferential direction of the first connecting piece, and second connecting holes are formed in the second connecting piece 4 corresponding to the first connecting holes. The first connecting hole and the second connecting hole are all cylindrical, and the axes of the corresponding first connecting hole and second connecting hole coincide and are all perpendicular to the plate surface of the first connecting piece 3. The screw structure further comprises a screw 6, the shaft of the screw 6 is arranged in the first connecting hole and the second connecting hole in a penetrating mode, and the head of the screw 6 is located on one side, away from the first connecting piece 3, of the second connecting piece 4. The length dimension of the shaft of the screw 6 is larger than the length dimension of the second connecting hole and smaller than the total length dimension of the first connecting hole and the second connecting hole, so that the screw 6 is prevented from damaging the pipeline 1. In the embodiment, the screw 6 is set as an inner hexagon screw, which is more suitable for the occasion with a narrower installation area and is convenient for realizing fastening. Moreover, the first connecting holes and the second connecting holes which are uniformly distributed along the circumferential direction of the pipeline 1 enable the first connecting piece 3 and the second connecting piece 4 to be more uniformly stressed when being connected through the threaded structure, so that a better fastening effect is achieved.
After the valve seat 22 and the valve body 21 are tightly screwed and sealed through the sealing gasket 23, the screw 6 is installed, and the rod body of the screw 6 passes through the second connecting hole and is positioned in the first connecting hole, so that the screwing state between the valve body 21 and the valve seat 22 is maintained as much as possible, and the phenomenon of water leakage between the valve body 21 and the valve seat 22 caused by accidental rotation of the valve seat 22 is avoided as much as possible; when it is desired to unscrew or unscrew the valve seat 22, the screw 6 is unscrewed or unscrewed, so that the second connecting piece 4 can be moved away from the first connecting piece 3, thereby separating the valve body 21 and the valve seat 22.
In addition, a gasket 7 is sleeved on the rod body of the screw 6, and the gasket 7 is positioned between the head of the screw 6 and the second connecting piece 4. During normal use, the abrasion generated between the screw 6 and the gasket 7 can compensate the abrasion of the screw 6 and the second connecting piece 4, so that the second connecting piece 4 is protected, and when the abrasion is serious, the screw 6 and the gasket 7 are replaced. Also, a cushion pad 5 is provided between the second connector 4 and the first connector 3, and the cushion pad 5 is made of an elastic material having a certain deformability, such as rubber, silica gel, etc. The buffer 5 is used to minimize the wear between the first connector 3 and the second connector 4 caused by excessive tightening of the screw 6, thereby protecting the first connector 3 and the second connector 4.
The implementation principle of the stop valve locking mechanism applied to the pipeline 1 is as follows: through the first connecting piece 3 fixedly installed on the valve body 21 and the second connecting piece 4 detachably connected with the first connecting piece 3 and fixedly installed on the valve seat 22, the possibility of re-rotating the valve seat 22 is reduced as much as possible after the valve seat 22 is screwed down, the connection tightness between the valve body 21 and the valve seat 22 is improved, and therefore the water leakage phenomenon caused by accidental rotation of the valve seat 22 is avoided.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
