Description
Technical Field
[0001] The utility model relates to the technical field of gas self-closing valve body processing, in particular to a fixing device for gas self-closing valve body processing. Background Art
[0002] Gas is a general term for gaseous fuels. It can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. Gas is mostly transported through pipelines and then connected to the stove through a special gas hose for use. In order to prevent gas leakage, a gas self-closing valve is often installed between the hose and the pipeline. When the gas is under-pressure, over-pressure, or pressure loss, the self-closing valve automatically closes. In the event of gas outage, abnormal gas supply, or hose detachment, the self-closing valve can also automatically close to prevent leakage. It is safe and reliable. In order to extend the service life of the self-closing valve, it is often necessary to spray the valve body surface with protective coating. Protective coating, when the existing gas self-closing valve body is produced, it is mostly fixed by pneumatic claws, and the valve body is fixed by squeezing the valve body surface with the claw head, and then the valve body surface is sprayed. When the traditional gas self-closing valve body is produced, the self-closing valve body is fixed by squeezing the valve body surface with two claws. The valve body is subjected to force at two points, and the valve body is easy to slip off, and the fixing effect is not good. When spraying, the position where the valve body surface contacts the claws cannot be sprayed, and secondary spraying is required. The valve body is fixed and there is a dead angle for spraying, which is not convenient for spraying and can easily cause uneven spraying of the protective coating. For this reason, we propose a fixing device for processing the gas self-closing valve body. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a fixing device for processing the valve body of a gas self-closing valve. The valve body can be fixed by contacting the inner wall of the valve body so that the force on the valve body in four directions is uniform and the fixing effect is good. The valve body does not contact the surface of the valve body and secondary spraying can be effectively avoided during spraying. The valve body can also be moved at multiple angles and in multiple directions to prevent the generation of spraying dead corners and make the protective coating sprayed more uniformly, which can effectively solve the problems in the background technology.

The four limit grooves are slidably connected to the limit slider through the limit column, which provides a basis for fixing the valve body. The valve body can be fixed by contacting the inner wall of the valve body so that the force on the four directions of the valve body is uniform. The fixing effect is good, and it does not contact the surface of the valve body. During spraying, secondary spraying can be effectively avoided.

[0007] Furthermore, the fixing mechanism also includes a stabilizing column, which is arranged at the front end of one side of the clamping block away from the middle of the limiting slider. The outer surface of the stabilizing column is slidably connected to the inner front end of the mounting column to provide stability and guidance for the movement of the clamping block.
[0008] Furthermore, the fixing mechanism also includes an electric push rod, which is arranged on the inner rear side of the mounting column, the input end of the electric push rod is electrically connected to the output end of the single-chip microcomputer, and the front end of the telescopic end of the electric push rod is fixedly connected to the rear end of the limit slider, so that the valve body can be quickly fixed and released.

[0011] Furthermore, both ends of the sliding column are square columns, and the middle part of the sliding column is a round column, which provides a basis for the deflection of the valve body angle.
[0012] Furthermore, bolt holes are provided at the lower ends of the left and right sides of the base to provide a fixing foundation for the base.
[0013] Furthermore, it also includes a single chip microcomputer, which is arranged in the middle of the right side of the base. The input end of the single chip microcomputer is electrically connected to an external power supply to provide a control effect for the fixation of the valve body.
[0014] Compared with the prior art, the utility model has the following beneficial effects: the fixing device for processing the valve body of the gas self-closing valve has the following advantages:
[0015] 1. The single chip microcomputer controls the operation of the electric push rod. The telescopic end of the electric push rod shrinks backward, driving the limit slider to move backward synchronously. At this time, as the limit slider moves, the limit column presses the limit groove, and moves the clamp block outward accordingly. The stabilizing column provides stability and guidance for the movement of the mounting column until the front ends of the four clamp blocks contact the inner wall of the valve body. The valve body is evenly stressed in four directions and is firmly fixed. During spraying, the clamp block will not contact the surface of the valve body, and no secondary spraying is required.
[0016] 2. The single-chip microcomputer controls the operation of the motor. The output shaft of the motor drives the gear to rotate, and the mounting column also rotates, and the valve body also rotates with it. At this time, spraying work is carried out. By continuously rotating the valve body, all parts of the valve body can be sprayed in place without leaving dead angles. In order to achieve the best spraying effect, it is also necessary to change the deflection angle of the valve body. Pull the handle to the right, and the sliding column and connecting rod also move to the right synchronously. The spring is compressed by force. At this time, the square column of the sliding column leaves the deflection seat, and the round column of the sliding column enters the inside of the rotating seat. The rotating seat loses its restriction and can be deflected 90 degrees up and down. The spraying effect of the valve body is improved by changing the deflection angle of the valve body. After the deflection is completed, just release the handle, the spring is not controlled by force, and brings the sliding column back to its original position. The square column of the sliding column is re-located inside the deflection seat, forming a restriction on the deflection seat, and moving the valve body at multiple angles and directions can prevent the generation of spraying dead angles while making the protective coating spray more evenly.

[0025] The fixing mechanism 4 includes a clamping block 41, a limiting groove 42, a limiting column 43 and a limiting slider 44.

The fixing mechanism 4 also includes a stabilizing column 45. The stabilizing column 45 is arranged at the front end of one side of the clamping block 41 away from the middle of the limiting slider 44. The outer surface of the stabilizing column 45 is slidably connected to the inner front end of the mounting column 3. The fixing mechanism 4 further comprises an electric push rod 46, which is arranged at the inner rear side of the mounting column 3, and the input end of the electric push rod 46 is electrically connected to the output end of the single-chip microcomputer 6. The front end of the telescopic end of the electric push rod 46 is fixedly connected to the rear end of the limit slider 44, so that the valve body can be quickly fixed and released. The fixing mechanism 4 further comprises a rotating assembly 47, which comprises a motor 471, a gear 472 and an inner gear ring 473. The motor 471 is arranged at the inner upper end of the deflection seat 2, and the input end of the motor 471 is electrically connected to the output end of the single-chip microcomputer 6. The gear 472 is arranged at the motor 47 1, an inner gear ring 473 is arranged at the rear end of the inner wall of the mounting column 3, and the gear 472 is meshed with the inner gear ring 473, so that the valve body can be rotated to prevent the generation of a dead angle for spraying. The fixing mechanism 4 also includes a deflection assembly 48, which includes a mounting groove 481, a slide column 482, a connecting rod 483, a spring 484 and a handle 485. The mounting groove 481 is opened in the middle of the front side of the base 1, and the slide column 482 is slidably connected to the inside of the mounting groove 481. The outer surface of the slide column 482 is installed in cooperation with the inner wall of the deflection seat 2, and the connecting rod 483 is fixedly connected to the right end of the slide column 482. The handle 485 is arranged on the connecting rod 483.

The two ends of the sliding column 482 are square columns, and the middle part of the sliding column 482 is a circular column, which provides a basis for the deflection of the valve body angle.

During spraying, secondary spraying can be effectively avoided. The valve body can also be moved at multiple angles and directions to prevent the generation of spraying dead angles while making the protective coating sprayed more evenly.
[0026] The working principle of the fixing device for processing the valve body of a gas self-closing valve provided by the utility model is as follows: when producing a gas self-closing valve, in order to extend the service life of the self-closing valve, it is necessary to spray an epoxy resin coating on the surface of the self-closing valve, pick up the valve body, insert the front side of the clamping block 41 into the interior of the valve body, and the single-chip computer 6 controls the electric push rod 46 to work. The telescopic end of the electric push rod 46 shrinks backward, driving the limit slider 44 to move backward synchronously. At this time, as the limit slider 44 moves, the limit column 43 presses the limit groove 42, bringing the clamping block 41 into contact with the valve body. 1 moves outwards, and the stabilizing column 45 provides stability and guidance for the movement of the mounting column 3 until the front ends of the four clamping blocks 41 contact the inner wall of the valve body, and the valve body is evenly stressed in four directions. The valve body is firmly fixed, and the spraying work begins after the valve body is fixed. When the epoxy resin coating is sprayed, the single chip computer 6 controls the motor 471 to operate, and the output shaft of the motor 471 drives the gear 472 to rotate. Because the gear 472 is meshed and connected with the inner gear ring 473, the mounting column 3 rotates with the rotation of the gear 472. Rotate, and the valve body rotates with it, and the spraying work is carried out at this time. By continuously rotating the valve body, all parts of the valve body can be sprayed in place without leaving dead angles. In order to achieve the best spraying effect, it is also necessary to change the deflection angle of the valve body, pull the handle 485 to the right, the slide column 482 and the connecting rod 483 also move to the right synchronously, and the spring 484 is compressed by force. At this time, the square column of the slide column 482 leaves the deflection seat 2, and the round column of the slide column 482 enters the interior of the rotating seat 2. The rotating seat 2 loses its restriction and can be deflected up and down. After the deflection is completed by ninety degrees, just release the handle 485, the spring 484 is not controlled by force, and the slide column 482 returns to its original position. The square column of the slide column 482 is re-located inside the deflection seat 2, forming a restriction on the deflection seat 2, and the valve body can be fixed by contacting the inner wall of the valve body, so that the valve body is evenly stressed in four directions, with good fixing effect, without contacting the surface of the valve body, and can effectively avoid secondary spraying during spraying. The valve body can also be moved at multiple angles and directions to prevent the generation of spraying dead corners while making the protective coating sprayed more evenly.
