Description

Technical Field

[0001] The invention belongs to the field of advanced manufacturing technology and relates to a special tool for quickly opening and closing a pipeline valve and a use method thereof. Background Art

[0002] At present, the environmental emission issues in places such as spray painting are receiving more and more attention. While ensuring the health needs of users, the degradation of paint mist on site must be dust-free. In view of these index requirements, the use of circulating water curtains is becoming more and more important. In order to ensure the safety of operators, reinforced grilles are laid above the water curtain pipes in the spray room. This means that every time the valve is opened to clean the paint residue in the water curtain pipe, the heavy grille must be lifted, which not only brings great labor intensity to maintenance personnel, but also takes up a lot of production time on site. Summary of the invention

[0003] In order to overcome the shortcomings of the above technology, the present invention proposes a special tool for quickly opening and closing valves in pipelines and a method for using the same. The manual device is welded and processed with 304 stainless steel material, and also has the advantages of simple structure and easy maintenance.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] In order to reduce the labor intensity and safe operation of the inspection and flushing drainage pipeline, the present invention transforms the drainage curtain pipeline of the painting line and the glue coating line. In order to completely solve the accumulated scale in the pipeline, a split turbine butterfly valve is added at the end. When the maintenance personnel flush and drain the accumulated scale in the cleaning pipeline, the scale can be flushed out smoothly from the valve installed at the end through the water pressure after manually opening the valve. A special tool for opening the valve (i.e., a special tool for quickly opening and closing the valve in the pipeline) is designed according to the appearance and size of the valve handwheel.

[0006] A special tool for quickly opening and closing valves in pipelines, the special tool consists of an operating mechanism, an extension rod and an operating handle. The operating mechanism is a cross frame and is equipped with four claws at four breakpoints; the bottom of the extension rod is welded to the operating mechanism, and the top of the extension rod is equipped with an operating handle.

[0007] When in use, hold the operating handle to clamp the claws of the special tool operating mechanism on the stop valve, and move the operating handle on the top by hand to open and close the stop valve.

[0008] The beneficial effects of the present invention are:

[0009] (1) This device tool is used to reduce the labor intensity and safe operation of the inspection and flushing drainage pipeline. The drainage curtain pipeline of the painting line and the glue coating line is modified. In order to completely solve the accumulated scale in the pipeline, a split turbine butterfly valve is added at the end. When the maintenance personnel flush and clean the accumulated scale in the pipeline, the water pressure is used to manually open the valve so that the scale can be smoothly flushed out from the valve installed at the end. It is also suitable for other stop valve remote quick switching and operation methods, which can greatly improve the switching efficiency of the stop valve at the wellhead of underground pipeline inspection, and reduce the frequency of maintenance personnel working in confined spaces, reducing the safety risks of personnel.

[0010] (2) This valve opening tool is specially made according to the appearance and size of the valve handwheel. When using this tool to open and close the valve, the maintenance personnel do not need to squat or bend down to operate, so as to prevent the muddy water splashed by the water pressure after the valve is opened from entering the eye. In addition, the hands do not touch the waste water when opening and closing the valve, which reduces the safety of the maintenance personnel. In addition, there is no need to open the heavy grille manually every time, which reduces labor intensity and improves maintenance efficiency.

[0011] (3) The present invention can ensure the safety of the site where operators use the device. There is no need to lift the heavy grille every time the valve is opened to clean the paint residue in the water curtain pipe. The maintenance personnel only need to open the inspection hole at the valve position of the exhaust grille floor, stand on one side of the inspection hole, and use this device to open or close the turbine clamp butterfly valve. The present invention not only reduces the labor intensity of maintenance personnel, but also shortens the time occupied for on-site production. That is, the present invention has the advantages of simple structure, no maintenance, simple and convenient maintenance operation, environmental protection, and high safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 A schematic diagram of the structure of the special tool provided by the present invention.

[0013] In the figure: 1 operating mechanism, 2 extension rod, 3 operating handle. DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with specific implementation cases.

[0015] A drain valve is installed at the end of the water curtain outlet pipe of the paint spraying line of the parts manufacturing center. The valve is placed under the grille. When this tool is not available, each time the drain valve is opened, it is necessary to first open the spray room exhaust fan to ensure that the fresh air flows the air in the spray room downward, open and remove the heavy grille, clear the paint mud around the valve, and enter the lower part of the grille to operate. During operation, it is also necessary to wear corresponding protective equipment to prevent paint mud from entering the eyes.

[0016] The steps of operating the valve using the special tool provided by the present invention are as follows:

[0017] The first step is to open the grille inspection port.

[0018] In the second step, a person stands on the grille and holds the tool handle to clamp the claw of the tool operating mechanism 1 on the top of the stop valve handle.

[0019] In the third step, manually rotate the operating handle 3 at the top of the tool extension rod 2, and the operating mechanism of the stop valve can rotate along with the operating handle 3.

[0020] Step 4: Stop rotation after reaching the desired opening and remove the operating mechanism 1.

[0021] The whole process can be completed within 5 minutes, greatly improving the switching efficiency of the entire valve.

[0022] The above-described embodiments merely express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
