Description

Technical Field

[0001] The utility model relates to the technical field of valve production, in particular to a detection device for valve production. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves usually consist of mounting flanges at both ends and an adjusting part in the middle.

[0003] The Chinese patent with the authorization announcement number CN211373419U discloses a diameter detection device for valve production. The diameter detection device for valve production includes: a base; a support rod, the bottom ends of the two support rods are fixed on the base, and a top plate is fixedly connected between the top ends of the two support rods; and a U-shaped plate. The diameter detection device for valve production provided by the utility model can quickly read the diameter of the valve body, and can detect the diameters of multiple valve bodies at one time. The operation is convenient and fast, and the detection status of the valve body diameter is reflected in a timely manner, avoiding large errors and thus reducing the defective rate. At the same time, by fixing the valve body, the diameter of the valve body is conveniently detected, avoiding displacement of the valve body during detection, which reduces the accuracy of the detection data, thereby effectively ensuring that the diameter of the produced valve body meets the quality requirements, further improving the practicality of the device.

[0004] However, in the implementation of relevant technologies, it was found that the design of the above-mentioned diameter detection device for valve production has the following problems: the use of a clamp to clamp the valve as a fixing method has the limitation that it is mainly suitable for valves of specific models. When it is necessary to replace and detect valves of other models, the problem of mismatch of the clamp size is often encountered, resulting in the valve being unable to be effectively fixed, which in turn affects the smooth progress of the detection work.

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the present utility model, provides a valve production detection device, including a main unit 100, a measuring unit 200 and a fixing unit 300.

[0027] The main unit 100 includes a base 101 and a vertical plate 102 mounted to match the base 101. The base 101 and the vertical plate 102 are an integrated structure for supporting the operation of the device.

[0028] The fixing unit 300 includes several groups of bidirectional screw rods 301 rotatably connected to one side of the vertical plate 102, one end of the bidirectional screw rod 301 is rotatably connected to a stabilizing plate 308, and both ends of the bidirectional screw rod 301 are threadedly connected to a moving block 304, and the outer surfaces of the two groups of moving blocks 304 are installed with several groups of evenly distributed connecting seats 305, and the connecting seat 305 is rotatably connected to a connecting rod 306 on the side away from the moving block 304, and the other end of the connecting rod 306 is rotatably connected to a fixed seat 309, and the fixed seat 309 is fixedly installed with an arc plate 307 on one end away from the bidirectional screw rod 301. A limited position structure is set on the outside of the bidirectional screw rod 301. The staff first moves the arc plate 307 is placed in the central cavity of the valve, and then the rotation of the bidirectional screw rod 301 is started. Since the two ends of the bidirectional screw rod 301 adopt a reverse thread design, its rotation action can prompt the moving blocks 304 on both sides of the rod body to move towards each other or away from each other under the guidance of the limiting structure. This movement process causes the tail of the connecting rod 306 connected to the connecting seat 305 to gradually gather, and then push the top of the connecting rod 306 to continue to extend outward. The top of the extended connecting rod 306 is tightly attached to and fixed to the valve through the arc plate 307, thereby achieving stable clamping of valves of various specifications, ensuring that the detection process is not affected by differences in valve models and proceeds smoothly.

[0029] The limiting structure includes a sliding rod 302 fixedly installed on both sides of the stabilizing plate 308, and the other end of the sliding rod 302 is fixedly connected to one side of the vertical plate 102. The sliding rod 302 passes through one side of the two sets of moving blocks 304, and the sliding rod 302 and the moving blocks 304 are slidably connected, and the moving blocks 304 are restricted from moving on the surface of the sliding rod 302.

[0030] A plurality of rotating wheels 303 are installed on one side of the vertical plate 102 , and one end of the rotating wheel 303 is fixedly connected to one end of the bidirectional screw rod 301 , and the bidirectional screw rod 301 is driven to rotate by rotating the rotating wheel 303 .

[0031] The measuring unit 200 includes a first connecting plate 203 and a second connecting plate 205 arranged on both sides of several groups of bidirectional screw rods 301. A scale plate 204 is fixedly installed on one side of the first connecting plate 203, and an identification strip 206 is fixed on one side of the second connecting plate 205. The inner wall of the identification strip 206 is in contact with the outer wall of the scale plate 204. The first connecting plate 203 and the second connecting plate 205 are moved toward the direction of the bidirectional screw rod 301. After the first connecting plate 203 and the second connecting plate 205 are close to the edge position of the valve, the staff can read the spacing of the identification strip 206 on the scale plate 204 to complete the measurement.

[0032] The top of the base 101 is symmetrically installed with mounting seats 201, and movable rods 202 are fixedly installed on the opposite surfaces of the two groups of mounting seats 201. The movable rods 202 and several groups of first connecting plates 203 and second connecting plates 205 are slidingly connected. The first connecting plates 203 and identification strips 206 can slide on the surface of the movable rods 202 to facilitate displacement.

[0033] The first connecting plate 203 and the second connecting plate 205 are located above the base 101, and the bottom ends of the first connecting plate 203 and the second connecting plate 205 are in contact with the top end of the base 101. The first connecting plate 203 and the second connecting plate 205 are in contact with the base 101, which serves to limit the first connecting plate 203 and the second connecting plate 205 to ensure that they are in a vertical state.

[0034] After the first and second connecting plates 203 and 205 are close to the edge position of the valve, the staff can read the spacing of the identification strips 206 on the scale plate 204 to complete the measurement.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
