Description

Technical Field

[0001] This application relates to the field of industrial automation technology, and in particular to a pressure testing fixture for a flow meter housing. Background Technology

[0002] As a precision instrument for measuring the flow rate of liquids or gases, flow meters are widely used in industries such as industry, agriculture, and chemical engineering. During the production and use of flow meters, ensuring the sealing and pressure resistance of each component, especially the housing, is an important prerequisite for ensuring the accuracy and reliability of the measurement. Usually, the flow meter housing needs to undergo rigorous pressure resistance and sealing tests before use to ensure that it maintains stable performance under different working environments.

[0003] In the existing technology, the pressure testing method for flow meter housings is mostly carried out manually. The existing technology involves installing the flow meter housing on a special pressure vessel or fixture, and then testing the pressure resistance and sealing performance of the housing by filling it with gas or liquid. Most of these traditional pressure testing fixtures are manually operated by operators, which often requires a lot of manpower and time. In addition, the existing fixtures are usually not very versatile and cannot be adapted to flow meter housings of different sizes or structures. The operation process is complicated and cannot effectively avoid errors caused by improper human operation.

[0004] Therefore, we need a flow meter housing pressure testing fixture to solve the problem that the existing flow meter housing pressure testing fixture cannot be applied to the pressure testing requirements of different models of flow meter housings, so that the flow meter housing pressure testing fixture can be applied to the pressure testing requirements of different models of flow meter housings. Utility Model Content

[0005] The purpose of this application is to solve the problem that the flow meter housing pressure testing fixture cannot be applied to the pressure testing requirements of different models of flow meter housings. In order to solve the above problem, this application provides a flow meter housing pressure testing fixture that can be applied to the pressure testing requirements of different models of flow meter housings.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: a base, on which a slide rail is provided; a fixed seat, which is located at the right end of the base and is fixedly connected to the base; a right-angle slide rail seat, which is located at the left end of the base and connected to the slide rail, and is arranged parallel to the fixed seat; two clamping flanges, which are respectively located inside the fixed seat and the right-angle slide rail seat; an adjusting handle, which is respectively located at the upper end of the right-angle slide rail seat and the clamping flange; and locking screws, which are provided at the four corners of the two clamping flanges, and are used to fix the two clamping flanges in series, and the locking screws cause the clamping flange on the right-angle slide rail seat to move axially towards the fixed seat by rotation.

[0007] In the above technical solution, the embodiment of this application uses a right-angle slide rail seat set at the left end of the base. The slide rail seat can slide left and right on the base, driving the displacement of the clamping flange. This allows the tooling to freely adjust the position of the slide rail seat according to the flow meter housing of different lengths, clamping different models of flow meter housings between two clamping flanges. This adapts to different models and specifications of flow meter housings, solving the problem that the flow meter housing pressure testing tooling cannot be applied to the pressure testing requirements of different models of flow meter housings. This makes the flow meter housing pressure testing tooling applicable to the pressure testing requirements of different models of flow meter housings.

[0008] Furthermore, according to an embodiment of this application, a sealing rubber ring is provided inside the clamping flange.

[0009] Furthermore, according to an embodiment of this application, the outer edge of the clamping flange is provided with a reinforcing rib structure.

[0010] Furthermore, according to an embodiment of this application, the contact surface on the inner side of the clamping flange is designed with an arc shape.

[0011] Furthermore, according to an embodiment of this application, the slide rail portion of the right-angle slide rail seat is provided with a locking device, which fixes the right-angle slide rail seat when it is adjusted to a predetermined position.

[0012] Furthermore, according to an embodiment of this application, the clamping flange is hinged to the fixed seat and the right-angle slide rail seat respectively via connecting pins.

[0013] Furthermore, according to the embodiments of this application, the locking screws are all arranged in parallel at the four corners of the clamping flange.

[0014] Furthermore, according to an embodiment of this application, the right-angle slide rail seat is fixed to the slide rail of the base by bolts, and the slide rail has scale markings.

[0015] Furthermore, according to an embodiment of this application, the adjustment handle portion has a structure with anti-slip texture.

[0016] Furthermore, according to an embodiment of this application, the clamping flange is movably connected to the fixed seat and the right-angle slide rail seat.

[0017] Compared with the prior art, this application has the following beneficial effects: This application uses a right-angle slide rail seat located at the left end of the base. The slide rail seat can slide left and right on the base, driving the displacement of the clamping flange. This allows the tooling to freely adjust the position of the slide rail seat according to the flowmeter housing of different lengths, clamping different models of flowmeter housings between two clamping flanges. This adapts to different models and specifications of flowmeter housings, solving the problem that flowmeter housing pressure testing tooling cannot be applied to the pressure testing requirements of different models of flowmeter housings. This makes the flowmeter housing pressure testing tooling applicable to the pressure testing requirements of different models of flowmeter housings. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and apparatus have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0034] Example 1: As Figure 1-5 As shown, a flow meter housing pressure testing fixture includes:

[0035] Base 1, with a slide rail 11 on it; fixed seat 2, located at the right end of base 1, and fixedly connected to base 1.

[0036] The right-angle slide rail seat 3 is located at the left end of the base 1 and connected to the slide rail 11. The right-angle slide rail seat 3 is set parallel to the fixed seat 2. The slide rail 11 on the base 1 cooperates with the right-angle slide rail seat 3 to adjust the left and right position of the slide rail seat, so that the tooling can adapt to flow meter housings of different lengths and specifications.

[0037] There are two clamping flanges 4. The clamping flanges 4 are respectively located inside the fixed seat 2 and the right-angle slide rail seat 3. The clamping flanges 4 can increase the contact area with the flow meter housing, prevent the flow meter housing from depressurizing, and the two clamping flanges 4 are arranged in parallel and symmetrically to ensure a tight fit with both sides of the flow meter housing.

[0038] Adjusting handle 5 is respectively set on the upper end of right angle slide rail seat 3 and clamping flange 4;

[0039] Locking screws 6 are provided at each of the four corners of the two clamping flanges 4. The locking screws 6 are used to fix the two clamping flanges 4 in series. By rotating the locking screws 6, the clamping flanges 4 on the right-angle slide rail seat 3 are axially displaced towards the fixed seat 2. The locking screws 6 are all parallel to each other at the four corners of the clamping flanges 4. The locking screws 6 at the four corners of the clamping flanges 4 ensure that the clamping flanges 4 are evenly stressed at all angles, avoiding uneven clamping caused by different flowmeter housing sizes. This ensures that different models of flowmeter housings are subjected to balanced force and stable clamping during pressure testing. By rotating the locking screws 6, the position of the clamping flanges 4 can be flexibly adjusted, ensuring that all models of housings can achieve good clamping effect.

[0040] A sealing rubber ring 7 is provided inside the clamping flange 4, and a reinforcing rib structure is provided on the outer edge of the clamping flange 4. The contact surface on the inner side of the clamping flange 4 is designed with an arc shape. The clamping flange 4 is reinforced with a reinforcing rib structure to enhance its rigidity and withstand high pressure test without deformation. The sealing rubber ring 7 inside the clamping flange 4 ensures good sealing of the flow meter housing during the pressure test and effectively prevents leakage.

[0041] A locking device 9 is provided at the connection between the right-angle slide rail seat 3 and the slide rail 11. When the right-angle slide rail seat 3 is adjusted to the predetermined position, the locking device 9 works to press against the base 1, fixing the right-angle slide rail seat 3 and preventing position displacement during the pressure test.

[0042] The clamping flange 4 is hinged to the fixed seat 2 and the right-angle slide rail seat 3 respectively by connecting pins. The connecting pins enable quick assembly and disassembly operations, and the clamping flange 4 can be easily replaced with different sizes to adapt to different sizes of flow meter housings.

[0043] The right-angle slide rail 3 is fixed to the slide rail 11 of the base 1 by bolts. The slide rail 11 has scale markings. The adjusting handle 5 has a structure with anti-slip texture. Through the scale markings and the anti-slip texture of the adjusting handle 5, the operator can quickly adjust to a suitable and correct position.

[0044] The clamping flange 4 is movably connected to the fixed seat 2 and the right-angle slide rail seat 3.

[0045] Example 2: Figure 6 As shown, based on Embodiment 1, this embodiment further improves the clamping flange 4, including:

[0046] A connecting part 41 is provided at the bottom of the clamping flange 4. The connecting part 41 is a hemispherical protrusion used to connect the clamping flange 4 with the fixed seat 2 and the right angle slide rail seat 3.

[0047] A concave spherical structure matching the connecting part 41 is provided on the inner side of the fixed seat 2 and the right-angle slide rail seat 3, so that the flange can rotate or tilt within multiple angles.

[0048] By fixing the locking screws around the clamping flange 4, when the flange is adjusted to the appropriate angle, the spherical structure is locked by friction, ensuring that the angle is fixed and does not shift.

[0049] The connection part 41 cooperates with the fixed seat 2 and the right angle slide rail seat 3 to allow the flange to be flexibly adjusted in multiple directions. The angle of the flange can be easily adjusted to make it fit precisely with the inclined surface of the flow meter housing. At the same time, the self-adaptive ability of the spherical structure ensures that the flange still maintains stable force and clamping effect in the inclined state, so that it can adapt to flow meter housings with non-standard shapes or inclination angles.

[0050] Example 3: Figure 1-6 As shown, based on Examples 1-3, this example also provides a method for using a flowmeter housing pressure testing fixture, including:

[0051] Clean the flow meter housing to be tested thoroughly to ensure that there are no impurities or contaminants on the surface, so as not to affect the sealing effect.

[0052] Place the fixture base 1 on a stable test platform to ensure the fixture is in a stable position.

[0053] Based on the length of the flow meter housing, adjust the position of the right-angle slide rail seat 3 and the position of the clamping flange 4 by means of the scale markings on the slide rail 11.

[0054] Place the flow meter housing between the fixed base 2 and the right-angle slide rail base 3, aligning both ends of the housing with the clamping flange 4 on the tooling.

[0055] Ensure good contact between the flow meter housing and the inner sealing rubber ring 7 of the clamping flange 4. The rubber ring is used to enhance the sealing effect.

[0056] Using the adjusting handle 5, rotate the adjusting handle 5 according to the size of the flow meter housing to adjust the clamping flange 4 on the right-angle slide rail seat 3 so that it is close to the fixed seat 2. The inner side of the clamping flange 4 is designed with an arc shape to ensure a tight fit with the outer wall of the flow meter housing, which can enhance the sealing effect.

[0057] Adjust the locking screws 6 on the four corners of the clamping flange 4 to fix the two clamping flanges 4 and ensure that the flow meter housing is evenly stressed at both ends.

[0058] After the clamping flange 4 is fixed and the seal is confirmed to be good, connect the test device to conduct a pressure test on the flow meter housing.

[0059] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
