Description

TECHNICAL FIELD

[0001] The utility model belongs to oilfield exploitation tool technical field, concretely relates to a rupture disc performance test evaluation device. BACKGROUND

[0002] The role of rupture disc performance test is mainly to evaluate the reliability and safety of rupture disc. Rupture disc is a safety device, which is usually used in pressure vessels, pipeline systems or other pressure equipment. When the pressure in the system exceeds the set value, the rupture disc will rupture to reduce the pressure and prevent the equipment from overloading or explosion.

[0003] The rupture disc used in the well is mainly used to block the oil pipe. When it is used, the ceramic piece in the rupture disc can be directly crushed to connect the oil pipe. Therefore, the pressure resistance of the ceramic piece is particularly important. In order to ensure the use of the ceramic piece under different pressures, the pressure resistance test needs to be carried out.

[0004] However, most of the existing rupture disc performance test equipment only records the pressure in the rupture disc when recording the pressure. When the ceramic piece is crushed under pressure, the pressure in the rupture disc changes suddenly. The pressure change on both sides of the ceramic piece in the rupture disc cannot be monitored for pressure determination. Since the traditional pressure gauge is far away from the installation position of the rupture disc, it is difficult to capture the pressure change in time at the moment of rupture of the ceramic piece, which reduces the accuracy of the pressure data.

[0005] Therefore, a rupture disc performance test evaluation device is designed to change the above technical defects. UTILITY MODEL CONTENTS

Detailed Implementation

[0024] This specific embodiment is a device for testing and evaluating the performance of a ruptured disc, and its structural schematic diagram is shown below. Figures 1-5 As shown, the test chamber 1 has an opening on its left side and a protective door 15 is fitted to its left side wall. The test chamber 1 contains a rupture disc body 2, which contains ceramic discs 3. Connectors 4 are located at both ends of the rupture disc body 2, each equipped with a pressure gauge 7. An mounting component 5 is installed on the side wall of the lower connector 4. A hydraulic cylinder 6 is fixedly installed on the bottom surface of the test chamber 1, and its output end is fixedly connected to the mounting component 5. A water supply tank 8 is located on the right side of the test chamber 1, and a water supply assembly is installed on the water supply tank 8. A water outlet pipe 11 is fixedly connected to the top of the upper connector 4, and the water outlet pipe 11 passes through the test chamber 1 and communicates with the water supply tank 8.

[0025] like Figure 3 and Figure 4 As shown, the water supply assembly includes a pressure pump 9 installed on the top surface of the water supply tank 8. A guide pipe 10 and an inlet pipe 12 are fixedly connected to the side walls of the pressure pump 9. The other end of the guide pipe 10 is connected to a lower connector 4, and the inlet pipe 12 extends into the inner cavity of the water supply tank 8. A filling pipe 14 is also provided on the top surface of the water supply tank 8. The filling pipe 14 allows observation of the water level in the water supply tank 8 during testing. If the water level is low, water can be added to the water supply tank 8 through the filling pipe 14 to ensure a stable water supply during the testing process.

[0026] In addition, the structures used in the water supply components are all existing and mature structures, so they will not be described in detail in this solution.

[0027] like Figure 4 As shown, a through hole is provided on the top surface of the water supply tank 8, and a filter cylinder 13 is installed inside the through hole. The other end of the water outlet pipe 11 extends into the water outlet pipe 11.

[0028] Specifically, when the ceramic disc 3 is crushed under pressure, the fragments will flow with the water in the outlet pipe 11. When the water flows into the water supply tank 8, the fragments will be collected in the filter cartridge 13 for easy cleaning and maintenance.

[0029] like Figure 5 As shown, sealing gaskets 16 are fixedly connected to the end faces of connectors 4, and the rupture disc body 2 abuts against the sealing gaskets 16. By setting the sealing gaskets 16, the sealing performance between the two connectors 4 and the rupture disc body 2 can be increased. The sealing gaskets 16 are generally made of materials such as rubber, silicone or nylon, which have good elasticity. When subjected to the extrusion force of the hydraulic cylinder 6, they can deform, thereby enhancing the sealing effect. After the hydraulic cylinder 6 is reset, the sealing gaskets 16 return to their original state.

[0030] Working principle: when the ceramic piece 3 in the rupture disc body 2 needs to be tested for compression resistance, the rupture disc body 2 is lifted in the test box 1, then the hydraulic cylinder 6 is started to drive the lower joint 4 to move upward through the mounting 5, so that the two side joints 4 are abutted against the two ends of the rupture disc body 2 and sealed by the sealing gaskets 16, then the changes of the two side pressure gauges 7 are recorded in real time, the water in the water supply tank 8 is continuously sent to the rupture disc body 2 through the lower joint 4 by starting the pressure pump 9, at the same time the pressure pump 9 is continuously pressurized, when the ceramic piece 3 is broken, the changes of the upper side pressure gauge 7 are recorded, through the highest value of the lower side pressure gauge 7 and the change value of the upper side pressure gauge 7, the compression resistance of the ceramic piece 3 can be obtained, and the spinal cord ceramic piece 3 is collected in the filter cylinder 13 with the water flow in the water outlet pipe 11.

[0031] All the technical features in the embodiment can be freely combined according to actual needs.

[0032] The above embodiment is a preferred implementation scheme of the utility model, in addition, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
