Description

Technical Field

[0001] The utility model relates to the field of valve size detection, in particular to a valve size detection structure. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. In order to meet the size requirements of valve production, valves need to be inspected for size.

[0003] For example, a valve size detection structure disclosed in the utility model with authorization announcement number CN219890383U relies on the operation of an electric telescopic rod, a cylinder and an electric two-way guide rail to change the position of a clamping plate, can accurately move to the measuring position of the valve body, and displays the size through a laser rangefinder, thereby realizing automatic detection of the valve body size. The operation is simple, and when the valve is inspected and processed, in order to ensure the accuracy of the detection, the valve itself needs to be positioned to prevent the valve from being offset in position during subsequent inspections, which affects the subsequent measurement results of the valve diameter. However, the current detection structure is difficult to effectively realize the positioning of the valve, which leads to data deviations in subsequent valve inspections. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a valve size detection structure, which can solve the problem that the existing valve size detection structure relies on the operation of an electric telescopic rod, a cylinder and an electric two-way guide rail to change the position of a clamping plate, can accurately move to the measuring position of the valve body, and display the size through a laser rangefinder, thereby realizing automatic detection of the valve body size, and the operation is simple. When the valve is detected and processed, in order to ensure the accuracy of the detection, it is necessary to position the valve itself to prevent the valve from being offset in position during subsequent detection, which affects the subsequent measurement results of the valve diameter. However, the current detection structure is difficult to effectively realize the positioning of the valve, resulting in a technical problem that data deviations are prone to occur during subsequent valve detection.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a valve size detection structure, including a base, a support column is fixedly installed at the top corner of the base, and a top beam is fixedly installed at the other end of the support column, a first spring is sleeved on the outer side of the top of the support column, and the other end of the first spring is fixedly connected to a lower pressure seat, a second spring is fixedly connected to the inner side of the bottom of the lower pressure seat, and the other end of the second spring is fixedly connected to a buffer seat, an arc groove is provided at the bottom of the buffer seat, a guide rod is vertically installed at the top of the lower pressure seat, and a third spring is sleeved on the outer surface of the guide rod, and a reading structure is provided on one side of the top of the lower pressure seat.

[0006] As a preferred technical solution of the utility model, the reading structure includes a scale and a pointer, a scale is vertically installed on the top side of the lower pressure seat away from the guide rod, and a pointer is installed on the top side of the top beam.

[0007] As a preferred technical solution of the utility model, a positioning seat is installed in the middle of the top of the base, and a rubber pad is provided on the inner wall of the top of the positioning seat. A supporting bottom is distributed on one side of the positioning seat, and a groove is opened at the top of the supporting bottom.

[0008] As a preferred technical solution of the utility model, the lower pressure seat is slidably connected to the support column through the first spring, and the two ends of the first spring are respectively fixedly connected to the bottom of the top beam and the top of one side of the lower pressure seat.

[0009] As a preferred technical solution of the present utility model, the buffer seat is slidably connected with the lower pressing seat through the second spring, and the arc groove and the buffer seat form an integrated structure.

[0010] As a preferred technical solution of the utility model, the guide rod and the lower press seat are vertically distributed, and the guide rod is symmetrically distributed along the vertical center line of the lower press seat.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The combination of the spring, the lower pressure seat and the buffer seat can effectively limit the lower pressure of the valve to be tested, thereby ensuring the stability of the valve in the subsequent testing process and preventing the position from shifting, which may lead to errors in the subsequent testing results. When the first spring and the third spring deform to produce a reverse force, the lower pressure seat will move longitudinally, and the arc groove at the bottom of the lower pressure seat can better match the valve, and the setting of the buffer seat can provide simple protection for the valve.

[0013] 2. The combination of the scale and the pointer can facilitate subsequent operators to read the test data more intuitively, which is convenient and quick. When the scale moves longitudinally with the lower pressure seat, the scale pointed by the pointer will also change accordingly. When the scale stops moving, the scale pointed by the pointer is the size of the valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] When in use, the valve to be tested is placed in the notch opened on the upper surface of the positioning seat 13, and the rubber pad 14 provided can provide simple protection for the bottom of the valve. At the same time, the two ends of the valve are respectively placed in the grooves 16 opened on the top of the supporting base 15, so as to facilitate the subsequent cooperation with the lower pressing seat 5 to better position the valve.

[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a first spring 4 is sleeved on the outer side of the top end of the support column 2, and the other end of the first spring 4 is fixedly connected to a lower pressure seat 5, and the lower pressure seat 5 is slidably connected to the support column 2 through the first spring 4, and the two ends of the first spring 4 are respectively fixedly connected to the bottom of the top beam 3 and the top of one side of the lower pressure seat 5, and the bottom inner side of the lower pressure seat 5 is fixedly connected to a second spring 6, and the other end of the second spring 6 is fixedly connected to a buffer seat 7, and an arc groove 8 is provided at the bottom of the buffer seat 7, and the buffer seat 7 is slidably connected to the lower pressure seat 5 through the second spring 6. The arc groove 8 and the buffer seat 7 form an integrated structure. A guide rod 9 is vertically installed on the top of the lower pressure seat 5, and a third spring 10 is sleeved on the outer surface of the guide rod 9. The guide rod 9 and the lower pressure seat 5 are vertically distributed, and the guide rod 9 is symmetrically distributed along the vertical center line of the lower pressure seat 5. A reading structure is provided on one side of the top of the lower pressure seat 5. The reading structure includes a scale 11 and a pointer 12. The scale 11 is vertically installed on the side of the top of the lower pressure seat 5 away from the guide rod 9, and a pointer 12 is installed on one side of the top of the top beam 3.

[0024] When the valve is placed on the positioning seat 13 set on the top of the base 1, the reverse force generated by the deformation of the first spring 4 and the third spring 10 will push the lower pressure seat 5 and the guide rod 9 respectively.

At the same time, when the lower pressure seat 5 moves longitudinally, the scale 11 will also slide longitudinally, and the pointer 12 fixedly installed at the top of the top beam 3 can facilitate the subsequent intuitive viewing of the valve size reading, that is, when the lower pressure seat 5 stops moving, the reading pointed to by the pointer 12 is the size of the valve, which is more convenient and quick, and has higher practicality;

[0025] Specific working principle:

[0026] The valve to be tested is placed in the notch opened on the upper surface of the positioning seat 13, and the rubber pad 14 provided can provide simple protection for the bottom of the valve. At the same time, the two ends of the valve are respectively placed in the groove 16 opened on the top of the support bottom 15. When the valve is placed on the positioning seat 13 provided on the top of the base 1, the reverse force generated by the deformation of the first spring 4 and the third spring 10 will push the lower pressure seat 5 and the guide rod 9 respectively. The reverse force generated by the deformation of the first spring 4 will realize the longitudinal movement of the lower pressure seat 5, and then the lower pressure seat 5 will move longitudinally along the support column 2, so as to improve the stability of the lower pressure seat 5 during the longitudinal movement. At the same time, the reverse force generated by the deformation of the third spring 10 will drive the guide rod 9 to move longitudinally, and then the guide rod 9 will move along the inner side of the top beam 3. The hole of the lower pressure seat 5 slides, further improving the stability of the lower pressure seat 5 during the longitudinal movement, and then the lower pressure seat 5 drives the buffer seat 7 arranged at its bottom to move longitudinally, and then when the buffer seat 7 contacts the upper surface of the valve, it will slide longitudinally, and then the buffer seat 7 squeezes the second spring 6, and causes it to deform and generate a reverse force. Combined with the reverse force generated by the deformation of the second spring 6, it can have a certain buffering effect, and thus can protect the upper surface of the valve. At the same time, when the lower pressure seat 5 moves longitudinally, it will drive the scale 11 to slide longitudinally, and the pointer 12 fixedly installed on the top of the top beam 3 can facilitate the subsequent intuitive viewing of the valve size reading, that is, when the lower pressure seat 5 stops moving, the reading pointed to by the pointer 12 is the size of the valve, which is more convenient and quick, and has higher practicality.
