The utility model discloses get up lead screw and flashboard junction protection, avoid the washing away and the corruption of medium, and do not influence the normal structure of opening and not changing the valve of valve, simple structure, low cost prevents that flashboard and lead screw from droing, prolongs the life of flashboard valve, alleviates worker intensity of labour, ensures oil field and other industry and agriculture normal production.
Description
Technical Field
The utility model relates to a valve design, manufacturing, maintenance technology are particularly a valve flashboard anticreep device.
Background
At present, in oil field production and other industrial and agricultural production, various gate valves are widely applied, due to corrosion, abrasion or improper operation of a medium, the situation that a gate plate and a lead screw fall off can occur in the opening and closing of the gate valve, and after the gate plate falls off, the work of replacing the gate is troublesome, the labor intensity of workers is high, and the normal production of the oil field and other industrial and agricultural is seriously influenced.
Disclosure of Invention
The utility model aims at above-mentioned weak point, in order to prevent that flashboard and lead screw from droing, it is troublesome to solve the work of changing the gate, and worker intensity of labour is big, seriously influences oil field and other industry and agriculture normal production problems, provides a valve flashboard anticreep device.
The utility model aims at being realized by the following technical scheme:
the utility model discloses a: the device comprises a body, a fixed screw, a valve flashboard and a valve lead screw; the method is characterized in that: the valve flashboard anti-falling device is a cylinder, an axial center hole is formed in the center of the body, an inverted U-shaped opening is formed in the lower portion of the body, a transverse threaded through hole is formed in the lower portion of the middle of the opening perpendicular to the lower portion of the middle of the opening, and a fixing screw is arranged in the threaded through hole.
The diameter of the central hole of the body in the valve flashboard anti-falling device is larger than that of the valve screw rod, and the opening width of the lower part of the body is larger than the thickness of the valve flashboard.
The lower part of the inverted T-shaped hanging opening of the valve flashboard in the valve flashboard anti-falling device is provided with a through hole with the diameter larger than that of the fixing screw.
The body in the valve flashboard anti-falling device is made of stainless steel materials or nylon materials.
The body in the valve flashboard anti-falling device is arranged at the hanging position of the valve flashboard and the valve lead screw.
The utility model has the advantages that: the valve is suitable for manufacturing new valves or maintaining old valves, the connecting part of the screw rod and the flashboard is protected, the flushing and corrosion of media are avoided, the normal opening of the valve is not influenced, the structure of the valve is not changed, the structure is simple, the cost is low, the flashboard and the screw rod are prevented from falling off, the service life of the flashboard valve is prolonged, the labor intensity of workers is reduced, and the normal production of oil fields and other industrial and agricultural industries is guaranteed.

FIG. 2-the utility model discloses the field application looks at half and cuts open the structure sketch map
In the figure, 1, a body, 2, a fixing screw, 3, a valve flashboard, 4, a valve pressing cap, 5, a valve lead screw and 6, a valve hand wheel are arranged; z. centre bore, L. screw thread through-hole, K. opening.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
As shown in fig. 1 and 2, an anti-drop device for a valve gate comprises a body 1, a fixing screw 2, a valve gate 3, and a valve lead screw 5; the method is characterized in that: a valve flashboard anticreep device is the cylinder, and the center of body 1 is equipped with axial centre bore Z, and the lower part is equipped with "U" type opening K of falling, is equipped with horizontal screw thread through-hole L in perpendicular to opening K's middle lower part, is equipped with set screw 2 in the screw thread through-hole L.
The diameter of the central hole Z of the body 1 is larger than that of the valve screw rod 5, and the width of the opening K at the lower part is larger than the thickness of the valve flashboard 3.
The lower part of the inverted T-shaped hanging opening of the valve flashboard 3 is provided with a through hole with the diameter larger than that of the fixing screw 2.
The body 1 is made of nylon material.
The body 1 is arranged at the hanging connection position of the valve flashboard 3 and the valve lead screw 5.
When the valve flashboard anti-drop device is used, firstly, the valve pressing cap 4 is detached, and the hand-held valve hand wheel 6, the valve lead screw 5 and the valve flashboard 3 are taken out of the valve body together; secondly, separating the valve screw rod 5 from the valve flashboard 3, and drilling a through hole at the position of the valve flashboard 3 corresponding to the threaded through hole L on the body 1; the third, overlaps body 1 on valve lead screw 5, and body 1 rebound articulates valve lead screw 5, valve flashboard 3, and body 1 rebound makes body 1 block valve flashboard 3, with fixed screw 2 body 1 and valve flashboard 3 fixed can. Thereby reach and prevent flashboard and lead screw and drop, prolong the life of flashboard valve, alleviate worker intensity of labour, ensure the purpose of oil field and other industry and agriculture normal production.
