Description

Technical Field

[0001] This utility model relates to the field of calibration bench technology, and in particular to a hydraulic safety valve fixed calibration bench. Background Technology

[0002] After production, hydraulic safety valves require testing using a calibration bench to verify their compliance with production standards. A safety valve calibration bench is an offline device that simulates the operating environment of a safety valve, raising the internal pressure to the point where the valve is ready to open. A pressure gauge on the bench displays the valve's opening pressure, allowing for the calibration of the opening pressure (also called the set pressure) and the sealing test pressure. Hydraulic safety valve calibration benches ensure the safety of tested safety valve equipment, preventing potential accidents and damage. They play a crucial role in industries such as energy and manufacturing. This article will introduce the advantages of safety valve calibration benches and their importance in the industrial field. However, commonly available fixed-type hydraulic safety valve calibration benches suffer from poor heat dissipation efficiency after prolonged use, affecting their lifespan. Furthermore, the test head structure wears down after repeated contact with the hydraulic safety valve, leading to a decrease in sealing performance. Utility Model Content

[0003] This disclosure relates to a fixed hydraulic safety valve calibration bench. When the temperature of the calibration bench body is high and heat dissipation efficiency needs to be improved, the control component can be used to pull the outer plate assembly to move and displace it, so that the sliding head assembly slides inside the slide groove. The outer plate assembly is separated from the inside of the side groove, exposing the heat dissipation groove and the connecting groove, so that the heat dissipation groove can quickly dissipate heat. At the same time, the connecting groove connects the outside with the inside of the calibration bench body, improving the heat dissipation effect and efficiency.

[0004] In a first aspect, this disclosure provides a fixed calibration bench for hydraulic safety valves, specifically comprising: a calibration bench body; an instrument and a control switch are provided at the front end of the calibration bench body, and a freely retractable outer plate assembly is installed on the side of the calibration bench body via a side groove; two outer plate assemblies are symmetrically arranged, and the rear ends of the two outer plate assemblies are fixedly connected via two control components; a test structure; the test structure is installed on the side of the calibration bench body, and the test structure is connected to the calibration bench body via wiring and pipelines; a detection head structure is installed at the top of the test structure via a fixed disc structure; a sealing structure is fitted outside the detection head structure; the sealing structure is an annular structure; the outer side of the rubber sealing structure is inclined; and an annular through hole is provided inside the sealing structure.

[0005] In at least some embodiments, an L-shaped side groove is provided on each side of the test bench body, and a connecting groove is provided on the inner rear end of each side groove, the interior of which is connected to the interior of the test bench body; heat dissipation grooves are provided on both sides of the test bench body, and the heat dissipation grooves are located inside the side grooves; a T-shaped sliding groove is provided on each side of the side groove, and a T-shaped sliding head assembly is inserted into the interior of each sliding groove and can be freely pulled out and pulled inside the sliding groove, and the sliding head assembly is welded and fixed to the inner bottom of the outer plate assembly.

[0006] In at least some embodiments, the test structure has two fixed disk structures, one large and one small, installed at its top. A detection head structure is installed at the middle of the top of the fixed disk structure. The inside of the detection head structure is connected to a pipeline. A movable structure is slidably installed inside the top of the fixed disk structure and is driven to slide freely. A support structure is welded to the top of the movable structure, and a connector structure is welded and fixed to the top of the support structure. A splice structure is inserted inside the connector structure, and the bottom of the splice structure contacts the top of the support structure. A baffle structure is fixed to the outside of the detection head structure, and the top of the baffle structure contacts the bottom of the sealing structure.

[0007] This utility model provides a fixed calibration bench for hydraulic safety valves, which has the following advantages:

[0008] When the temperature of the test bench itself is high and heat dissipation efficiency needs to be improved, the control component can be used to pull the outer plate component to move and displace it, so that the sliding head component slides inside the slide groove. The outer plate component is separated from the inside of the side groove, exposing the heat dissipation groove and the connecting groove, so that the heat dissipation groove can quickly dissipate heat. At the same time, the connecting groove connects the outside with the inside of the test bench body, improving the heat dissipation effect and efficiency.

[0009] During the testing of the hydraulic safety valve, after the hydraulic safety valve is fixed, it is connected to the sealing structure. At the same time, the hydraulic safety valve is continuously pressed down, squeezing the sealing structure. Since the outer side of the sealing structure is inclined and made of rubber, it can contact and seal with hydraulic safety valves of different sizes, improving the sealing effect and sealing strength. Even if the sealing structure is worn or the sealing performance decreases, the sealing structure can be pulled up directly, making it easy to remove and replace, thus improving replacement efficiency.

[0023] Example 1: Please refer to Figures 1 to 6 :

[0024] This utility model proposes a fixed hydraulic safety valve testing bench, comprising: a testing bench body 1; the front end of the testing bench body 1 is equipped with an instrument and a control switch, and the side of the testing bench body 1 is fitted with a freely retractable outer plate assembly 106 via a side groove 101. Two outer plate assemblies 106 are symmetrically arranged, and the rear ends of the two outer plate assemblies 106 are fixedly connected via two control components 107. The control components 107 can be used to conveniently control the free retraction of the outer plate assembly 106 within the side groove 101, quickly exposing the heat dissipation groove 103 and the connecting groove 102, allowing the testing bench body 1 to dissipate heat quickly and improving heat dissipation efficiency; a test structure 2; the test structure 2 is installed... Installed on the side of the calibration bench body 1, the test structure 2 is connected to the calibration bench body 1 through lines and pipes. The top of the test structure 2 is equipped with a test head structure 206 through a fixed plate structure 201. The test head structure 206 is fitted with a sealing structure 208. The sealing structure 208 is a ring-shaped structure. The rubber sealing structure 208 has an inclined outer side to contact hydraulic safety valves of different sizes, thereby improving the sealing effect and sealing strength. Even if the sealing structure 208 is damaged, it can be easily pulled up and removed for replacement, improving replacement efficiency. The sealing structure 208 has an annular through hole inside to improve its flexibility.

[0025] In this embodiment of the disclosure, such as Figure 3 and Figure 4 As shown, each side of the test bench body 1 has an L-shaped side groove 101, allowing the outer plate assembly 106 to be freely pulled out and used inside. Each side groove 101 has a connecting groove 102 on its rear inner side, and the interior of the connecting groove 102 is connected to the interior of the test bench body 1. After the connecting groove 102 is exposed, the exterior is connected to the interior of the test bench body 1, improving the heat dissipation effect. Each side of the test bench body 1 has a uniformly arranged heat dissipation groove 103, which is located inside the side groove 101. Each side of the side groove 101 has a T-shaped sliding groove 104, and a T-shaped sliding head assembly 105 is inserted into the interior of each sliding groove 104 and can be freely pulled out and used inside the sliding groove 104. The sliding head assembly 105 is welded and fixed to the inner bottom of the outer plate assembly 106, so that the outer plate assembly 106 can be guided and pulled out, making the side groove 101 easy to open, improving the heat dissipation effect and efficiency.

[0026] In this embodiment of the disclosure, such as Figure 5 and Figure 6As shown, the top of the test structure 2 is equipped with two fixed disc structures 201, one large and one small, which can fix different models of hydraulic safety valves. A detection head structure 206 is installed in the middle of the top of the fixed disc structure 201. The interior of the detection head structure 206 is connected to the pipeline. A movable structure 202 is slidably installed inside the top of the fixed disc structure 201, and the movable structure 202 can be driven to slide freely, clamping the hydraulic safety valve. A support structure 203 is welded to the top of the movable structure 202, and a connector structure 204 is welded and fixed to the top of the support structure 203. A splice structure 205 is inserted inside the connector structure 204, allowing the splice structure 205 to be freely replaced and installed. The bottom of the splice structure 205 contacts the top of the support structure 203. A baffle structure 207 is fixed to the outside of the detection head structure 206. The top of the baffle structure 207 contacts the bottom of the sealing structure 208, firmly supporting the sealing structure 208 and improving the support and sealing effects.

[0027] The working principle of this embodiment is as follows: When the hydraulic safety valve needs to be calibrated, the hydraulic safety valve to be calibrated can be directly controlled to be placed inside the fixed plate structure 201. The displacement of the moving structure 202 is controlled so that the splicing joint structure 205 can be clamped by force, improving the clamping and fixing effect of the hydraulic safety valve. The hydraulic safety valve is then moved downward by force, and the bottom of the hydraulic safety valve contacts the outside of the sealing structure 208. Since the sealing structure 208 is made of rubber, the sealing effect and sealing strength can be improved after it is subjected to force. Then, the calibration bench body 1 is controlled to operate to calibrate the hydraulic safety valve. During the calibration process, data can be displayed through various instruments. If the temperature of the calibration bench body 1 is too high, the outer plate assembly 106 can be pulled backward by the control component 107 to open the side groove 101, so that the heat dissipation groove 103 can be opened to dissipate heat. At the same time, the connecting groove 102 connects the outside with the inside of the calibration bench body 1, improving the heat dissipation effect and efficiency.
