Description

Technical Field

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

[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] Before the valve leaves the factory, it is necessary to use a valve size standard detection structure to detect the valve size. When detecting the valve diameter, the existing valve size detection device usually needs to detect the outer diameter and inner diameter of the valve separately, which is cumbersome to operate and inconvenient to adjust the clamping according to different valve sizes.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a valve size standard detection mechanism is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a valve size standard detection mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve size standard detection mechanism, including a measuring instrument base and a sliding support seat, a first slide rail is opened inside the measuring instrument base, the sliding support seat is slidably connected to the inside of the first slide rail, and the sliding support seat is arranged on the top of the measuring instrument base, a handle is fixedly connected to the front outer wall of the sliding support seat, and a first telescopic rod is fixedly connected to the top of the sliding support seat, four first telescopic rods are arranged, and a support block is fixedly connected to the outer wall of the top end of the first telescopic rod.

[0007] Furthermore, a clamping assembly for clamping is arranged above the sliding support seat, and the clamping assembly includes a motor and a screw rod. The motor is fixed to the top outer wall of the first telescopic rod, and the end of the motor is connected to the screw rod.

[0008] Furthermore, the clamping assembly also includes a transmission belt and a clamping piece. The outer wall of the end of the motor is meshedly connected with the transmission belt, and the outer wall of the screw rod is provided with a clamping piece.

[0009] Furthermore, a second telescopic rod is fixed to the right top outer wall of the measuring instrument base, and the height of the top end of the second telescopic rod is higher than the height of the top outer wall of the clamping piece.

[0010] Furthermore, a measuring assembly for measuring is connected to the top end of the second telescopic rod, and the measuring assembly includes a support rod and a second slide rail, and the second slide rail is provided inside the support rod.

[0011] Furthermore, the measuring assembly further comprises a first measuring ruler and a second measuring ruler, and the first measuring ruler and the second measuring ruler are slidably connected inside the second slide rail.

[0012] Furthermore, a first positioning block is connected to the bottom outer wall of the first measuring ruler, and a second positioning block is fixed to the front end of the second measuring ruler.

[0013] Furthermore, the first positioning block and the second positioning block are both arranged in front of the support rod, and the height of the bottom ends of the first positioning block and the second positioning block is higher than the height of the top outer wall of the clamping piece.

[0014] The utility model provides a valve size standard detection mechanism, which has the following beneficial effects:

[0015] 1. The valve size standard detection mechanism adjusts the height of the top end of the first telescopic rod according to the height of the valve to be detected, so that the subsequent clamping piece can clamp the waist of the valve to be detected. The rotation of the end of the motor drives the screw rod to rotate, and the rotation of the screw rod drives the two clamping pieces to move.

[0016] 2. The valve size standard detection mechanism slides the first measuring ruler and the second measuring ruler inside the second slide rail, reads the data by observing the distance scale between the second measuring ruler and the front outer wall of the support rod, and reads the data by observing the distance scale between the first measuring ruler and the front outer wall of the support rod, thereby realizing simultaneous measurement of the inner diameter and the outer diameter of the hole without moving the valve to be detected, thereby improving the measurement efficiency.

[0023] The specific operation is as follows: place the measuring instrument base 1 on a horizontal ground, place the valve opening of the valve to be tested in close contact with the top center of the sliding support seat 3, and adjust the height of the top end of the first telescopic rod 5 according to the distance between the two valve openings of the valve to be tested, so that the subsequent clamping piece 704 can clamp the waist of the valve to be tested;

[0024] Start the motor 701. The end of the motor 701 rotates to drive the screw rod 702 to rotate, and at the same time drives the transmission belt 703 to drive. The transmission belt 703 drives the other screw rod 702 to rotate. The end of the screw rod 702 slides inside the support block 6. The rotation of the screw rod 702 drives the two clamping pieces 704 to move. The two clamping pieces 704 move closer to each other. The two clamping pieces 704 clamp the outer wall of the valve to be tested to prevent the position of the valve to be tested from being offset in subsequent measurements.

[0025] like Figure 1-Figure 3As shown, a second telescopic rod 8 is fixed to the right top outer wall of the measuring instrument base 1, and the top end height of the second telescopic rod 8 is higher than the top outer wall height of the clamping piece 704, and a measuring component 9 for measuring is connected to the top end of the second telescopic rod 8, and the measuring component 9 includes a support rod 901 and a second slide rail 902, and the support rod 901 is provided with a second slide rail 902 inside, and the measuring component 9 also includes a first measuring ruler 903 and a second measuring ruler 904, and the first measuring ruler 903 and the second measuring ruler 904 are slidably connected inside the second slide rail 902, and the bottom outer wall of the first measuring ruler 903 is connected to a first positioning block 10, and the front end of the second measuring ruler 904 is fixed with a second positioning block 11, and the first positioning block 10 and the second positioning block 11 are both arranged in front of the support rod 901, and the bottom end heights of the first positioning block 10 and the second positioning block 11 are higher than the top outer wall height of the clamping piece 704;

[0026] The specific operation is as follows: the top height of the second telescopic rod 8 is adjusted according to the height of the valve to be tested, and the support rod 901 moves up and down accordingly. The handle 4 is held to push the sliding support seat 3, and the bottom end of the sliding support seat 3 slides inside the first slide rail 2. When the clamped valve to be tested moves to a suitable position below the measuring component 9 with the movement of the sliding support seat 3, the sliding support seat 3 is positioned by the fixing bolt, thereby saving effort and reducing manual operation and movement.

[0027] The first measuring ruler 903 and the second measuring ruler 904 are slid inside the second slide rail 902 to measure the aperture of the valve to be tested. When measuring the outer diameter of the aperture of the valve to be tested, the rear outer wall of the second positioning block 11 is pressed against the outer wall of the valve to be tested, and the distance scale between the second measuring ruler 904 and the front outer wall of the support rod 901 is observed to read the value;

In this way, the inner and outer diameters of the hole can be measured simultaneously without moving the valve to be tested, thereby improving the measurement efficiency.

[0029] In summary, if Figure 1-Figure 3As shown, when using the valve size standard detection mechanism, first place the measuring instrument base 1 on the horizontal ground, place the valve opening of the valve to be detected in the center of the top of the sliding support seat 3, adjust the height of the top end of the first telescopic rod 5 according to the distance between the two valve openings of the valve to be detected, start the motor 701, the end of the motor 701 rotates to drive the screw rod 702 to rotate, and at the same time drives the transmission belt 703 to drive, the transmission belt 703 drives another screw rod 702 to rotate, the end of the screw rod 702 slides inside the support block 6, the rotation of the screw rod 702 drives the two clamping pieces 704 to move, the two clamping pieces 704 move closer, and the two clamping pieces 704 clamp the outer wall of the valve to be detected;

[0030] The top height of the second telescopic rod 8 is adjusted according to the height of the valve to be detected, and the support rod 901 moves up and down accordingly. The handle 4 is held to push the sliding support seat 3, and the bottom end of the sliding support seat 3 slides inside the first slide rail 2. When the clamped valve to be detected moves to a suitable position below the measuring component 9 with the movement of the sliding support seat 3, the sliding support seat 3 is positioned by the fixing bolt, and the aperture of the valve to be detected is measured by sliding the first measuring ruler 903 and the second measuring ruler 904 inside the second slide rail 902.
