Description

Technical Field

[0001] This invention relates to the field of ultra-high pressure valve testing technology, and in particular to an online testing system for ultra-high pressure valves. Background Technology

[0002] Ultra-high pressure valves refer to valves whose working pressure is much higher than conventional industrial standards, typically exceeding 100MPa, 1000Bar, or even 1000MPa. These are specialized valves used for fluid control in extremely high-pressure environments. Ultra-high pressure valves are suitable for oil and natural gas applications, such as ultra-deep well drilling equipment, high-pressure oil and gas pipelines, and scientific research experiments. Ultra-high pressure valves are usually made of high-strength alloy steel, titanium alloy, or special composite materials, which are impact-resistant and fatigue-resistant. However, sealing technology remains a technical adjustment that needs to be overcome.

[0003] Chinese Patent CN 115326315 A discloses an airtightness testing device and test for an ultra-high pressure hydraulic valve, including an experimental platform, a rotating mechanism, an ultra-high pressure valve clamping assembly, an ultra-high pressure testing assembly, and a residual air extraction assembly. The rotating mechanism is mounted on the experimental platform, and the ultra-high pressure valve clamping assembly is mounted on the rotating part of the rotating mechanism for clamping the valve body of the ultra-high pressure hydraulic valve. The ultra-high pressure testing assembly is sealed to the ultra-high pressure valve clamping assembly and communicates with the interior of the valve body of the ultra-high pressure hydraulic valve. The residual air extraction assembly includes a vacuuming integrated block, a vacuuming tube, and a spring clamping unit. This device enables ultra-high pressure testing of ultra-high pressure hydraulic valves and can extract as much residual air as possible from the valve body, avoiding the explosion safety risk caused by high-pressure gas.

[0004] However, this technical solution does not take into account the problem that operators cannot operate at close range during high-pressure testing, and it does not simulate actual working conditions online, such as the working conditions when a medium containing impurities passes through. Furthermore, it fails to realize the function of online cleaning and observation of cleaning test results after simulation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an online testing system for ultra-high pressure valves. This system uses a flow assembly to pass a medium containing impurities through the ultra-high pressure valve, enabling testing of the valve under such operating conditions. An angle adjustment assembly, in conjunction with an observation assembly, allows for remote observation of the valve's sealing performance after testing. Furthermore, the angle adjustment assembly, along with a cleaning assembly and a water spray assembly, enables the cleaning of the ultra-high pressure valve, including cleaning of small, hard-to-reach crevices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0042] The limiting rod is I-shaped and is located in the limiting hole, through which several sets of limiting plates are connected to ensure a tight fit; one end of the limiting rod is connected to the fixing sleeve.

[0043] It should be noted that the limiting rod connects the limiting plate to the fixed sleeve, and the telescopic rotary cylinder drives the adjusting rod to rotate inside the limiting plate, thereby causing the brush bristles to retract tangentially into the receiving groove through the guide groove, making the protruding part of the brush shorter. Conversely, the telescopic rotary cylinder rotates in the opposite direction, making the protruding part of the brush longer. The length of the protruding brush can be adjusted by the telescopic rotary cylinder to clean the gaps of the ultra-high pressure valve.

The upper second fixing seat is for pressing the second fixing seat and the lower second fixing seat is for positioning the second fixing seat. The second fixing seat has a "convex" track groove and two sets of grooves are provided.

[0059] The second guide rod is used to guide the displacement of the second fixed seat. It is fixedly mounted on the second fixed seat and there are two sets of them.

[0060] The fixing plate has an arc-shaped upper end with the arc size corresponding to the outer diameter of the ultra-high pressure valve. The fixing plate is mounted on the second fixing seat and has two sets of corresponding fixing plates.

[0061] The fourth drive assembly has its output end connected to the second fixed base for pressing, driving it to reciprocate vertically to press the ultra-high pressure valve.

[0062] As an improvement, the axial clamping assembly includes:

[0063] The clamping rod has threads at both ends, one set of which is positive and the other set of which is negative. The threads pass through the track groove and are rotatably mounted on the second fixed seat.

[0066] As an improvement, a wastewater return port is provided on the side of the base to return the wastewater generated during cleaning to the water tank.

[0067] The beneficial effects of this invention are as follows:

[0068] (1) The present invention uses a flow component to pass a medium containing impurities through an ultra-high pressure valve. Under the working conditions of ultra-high pressure and impurities in the fluid, the valve is repeatedly opened and closed several times to detect valve leakage. This realizes online automatic detection of ultra-high pressure valves and solves the problem in the prior art that leakage test is only performed when the valve is closed, and leakage under actual working conditions cannot be detected.

[0069] (2) The present invention drives the rack to move back and forth on the slide rail slider assembly through the third drive component, thereby driving the rotation of the adjustment roller so that the angle adjustment component can realize the function of adjusting the angle, realize remote observation of the sealing performance of the ultra-high pressure valve after testing, and ensure the safety of the operator.

[0070] (3) The present invention uses a rotating cylinder in the water spraying assembly to make the water spraying assembly rotate and spray water, so as to achieve cleaning of the ultra-high pressure valve over a wider range. The present invention uses a telescopic rotating electric cylinder in the cleaning assembly to make it reciprocate and rotate to achieve cleaning. The water spraying assembly and the cleaning assembly are alternately arranged along the circumference of the rotating roller to achieve cleaning of the ultra-high pressure valve.

[0071] (4) The present invention connects the limiting plate to the fixed sleeve through the limiting rod, and drives the adjusting rod to rotate inside the limiting plate through the telescopic rotary cylinder, thereby causing the brush bristles to move along the tangential direction through the guide groove, thereby adjusting the length of the brush bristles. This makes it suitable for cleaning some narrow spaces of ultra-high pressure valves that are difficult to clean under different working conditions. For example, when the ultra-high pressure valve is in the detection state, the gap formed between the valve plate and the ultra-high pressure valve in the closed state can be cleaned by the brush bristles at one end of the adjusting rod. Another example is when the ultra-high pressure valve is in the cleaning state, the gap formed between the valve plate and the ultra-high pressure valve in the closed state can be cleaned by adjusting the length of the brush bristles through the telescopic rotary cylinder, extending them into the gap, and then the telescopic rotary cylinder extends and retracts, causing it to brush repeatedly in the gap, thereby cleaning the ultra-high pressure valve.

[0072] In summary, the present invention has advantages such as adjustability, remote observation capability, and security. Attached Figure Description

[0092] Example 1

[0093] like Figure 1-3 As shown, this embodiment provides an online testing system for ultra-high pressure valves, including a base 1; a clamping assembly 2, which tightly fits the ultra-high pressure valve to keep it in a closed state for conveying the medium, and is mounted on the base 1, with two sets of clamping assemblies symmetrically arranged; a cleaning assembly 3, which is used to clean the ultra-high pressure valve after testing, and is rotatably mounted on the clamping assembly 2, with several sets arranged at equal angles along the circumference of the clamping assembly 2; an observation assembly 4, which is used to observe whether the valve leaks under high pressure conditions after cleaning, and is rotatably mounted on the clamping assembly 2; a flow assembly 5, which is used to convey the medium and is connected to the clamping assembly 2; a control console 6; and a clamping assembly 7, which is used to fix and lock the ultra-high pressure valve, and is mounted on the base 1.

[0094] As an improvement, the clamping assembly 2 includes:

[0095] Frame 21, which is mounted on base 1;

[0096] Push rod 22, which is rotatably mounted on frame 21, and has a medium conveying channel inside its front end;

[0097] Sealing sleeve 23, such as Figure 3 As shown, the sealing sleeve 23 is a boss-shaped structure, with one end connected to the push rod 22, preferably by bolts. The other end face is provided with a sealing ring 231. The sealing sleeve 23 is located at the end of the push rod 22 near the ultra-high pressure valve. The sealing sleeve 23 and the push rod 22 are connected separately, and can be disassembled and replaced to suit ultra-high pressure valves of different sizes.

[0098] First drive assembly 24, the output end of the drive assembly is connected to push rod 22, and the drive assembly preferably adopts a hydraulic cylinder;

[0099] The first guide rod 25 has two ends fixed on two sets of frames 21. The first guide rod 25 has two sets and is arranged diagonally.

[0100] Guide plate 26 is slidably mounted on first guide rod 25 and fixedly mounted on push rod 22. Guide plate 26 reciprocates axially with push rod 22.

[0101] It should be noted that the first drive assembly 24 drives the push rod 22 to reciprocate axially along the first guide rod 25, so that the sealing sleeve at the front end of the push rod 22 is tightly connected to the ultra-high pressure valve 23. Under the online simulation of ultra-high pressure and fluid containing impurities, the valve is repeatedly opened and closed several times to detect valve leakage, thereby realizing online automatic detection of ultra-high pressure valve. This solves the problem in the prior art that only the leakage test is performed when the valve is closed, and leakage under the actual opening and closing conditions of the valve cannot be detected.

[0102] Example 2

[0103] like Figure 4-10 As shown in Figures 13-16, components that are the same as or corresponding to those in Embodiment 1 are referenced using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that, as an improvement, as... Figure 4 As shown, the cleaning component 3 includes:

[0104] Rotating roller 31, which is rotatably mounted on push rod 22, with one end abutting against guide plate 26 and the end away from guide plate 26 being mounting end 311;

[0105] The second drive assembly 32 is mounted on the guide plate 26, and its output end is connected to the rotating roller 31 for transmission. One end of the rotating roller 31 is provided with a transmission gear, which is driven by a small gear provided at the output end of the second drive assembly 32. The drive assembly preferably adopts a geared motor.

[0106] It should be noted that the drive end of the rotating roller 31 and the end connected to the drive assembly are provided with a waterproof cover to prevent it from being affected by sewage splashed during cleaning during the test.

[0107] Angle adjustment assembly 33, several sets of angle adjustment assemblies 33 are arranged circumferentially along the rotating roller 31;

[0108] Water spray assembly 34 is used to spray water to clean ultra-high pressure valve. It is rotatably mounted on angle adjustment assembly 33 and moves with angle adjustment assembly 33. The water spray assembly 34 is provided with several groups at equal angles along the normal of rotating roller 31.

[0109] Cleaning assembly 35 is used to clean ultra-high pressure valve. It is rotatably mounted on the angle adjustment assembly and moves with the angle adjustment assembly 33. The cleaning assembly 35 is provided with several groups at equal angles along the normal of the rotating roller 31.

[0110] The water spraying assembly 34 and the cleaning assembly 35 are alternately arranged along the circumference of the rotating roller 31.

[0111] As an improvement, such as Figure 5 As shown, the angle adjustment component 33 includes:

[0112] The first fixing seat 331 is fixedly mounted on the mounting end 311;

[0113] The adjusting roller 332 is cylindrical in shape, with teeth on a portion of its circumferential direction and a mounting groove 3321 on the corresponding untoothed portion. The adjusting roller 332 is rotatably mounted on the first fixed seat 331.

[0114] The slide rail and slider assembly 333 is provided with the slide rail mounted on the first fixed base 331 and the slider slidably mounted on the slide rail.

[0115] Rack 334, which is fixedly mounted on slide rail slider assembly 333 and connected to gear rack 334 of adjusting roller 332;

[0116] The third drive assembly 335 is mounted on the first fixed base 331, and its output end is connected to one end of the rack 334. The drive assembly preferably adopts an electric cylinder. The third drive assembly 335 drives the rack 334 to move back and forth, thereby driving the adjusting roller 332 to rotate.

[0117] It should be noted that the third drive component 335 drives the rack 334 to reciprocate on the slide rail slider component 333, thereby driving the rotation of the adjusting roller 332 so that the angle adjusting component 33 can achieve the function of adjusting the angle.

[0118] As an improvement, the water spray assembly 34 includes:

[0119] Rotary cylinder 341, such as Figure 10 As shown, the rotary cylinder 341 is fixedly mounted on the mounting groove 3321; it should be noted that the rotary cylinder is used to rotate the water spray assembly to spray water, so as to achieve cleaning of the ultra-high pressure valve over a wider range.

[0120] Nozzle 342, such as Figure 6 As shown, one end of the nozzle 342 is fixedly connected to the rotary cylinder 341.

[0121] As an improvement, the cleaning assembly 35 includes:

[0122] Telescopic rotary cylinder 351, such as Figure 10 As shown, the telescopic rotary cylinder 351 is fixedly mounted on the mounting groove 3321;

[0123] Brush assembly 352, which is connected to telescopic rotary cylinder 351.

[0124] As an improvement, such as Figure 7 As shown, the brush assembly 352 includes:

[0125] The fixing sleeve 3521 is a hollow cylinder, one end of which is fixedly connected to the adjusting roller 332.

[0126] Adjusting rod 3522, which is located inside fixed sleeve 3521, with one end connected to telescopic rotary cylinder 351;

[0127] Furthermore, the adjusting rod 3522 is provided with a plurality of receiving grooves 35221 at equal intervals along its axial direction, and a plurality of bristles 100 are evenly distributed in the receiving grooves 35221 along its circumference; the receiving grooves 35221 are used to provide space for the bristles 100 to rotate, thereby avoiding deformation or breakage.

[0128] It should be noted that the other end of the adjusting rod 3522 is provided with several bristles 100, which are used to clean the gap between the valve plate and the valve when the ultra-high pressure valve is closed.

[0129] Limit plate 3523, such as Figure 8 As shown, the limiting plate 3523 is semi-circular, and its front and back are symmetrically provided with guide grooves 35231 for guiding the movement path of the brush bristles 100. The limiting plate 3523 is provided with a plurality of limiting holes 35232. The guide grooves 35231 are used to limit and guide the brush bristles 100, so that they move along the trajectory of the guide grooves 35231.

[0130] The guide groove 35231 is arranged along the tangential direction of the outer diameter surface of the adjusting rod 3522.

[0131] It should be noted that the guide groove 35231 allows the bristles 100 to move smoothly in and out during the rotation of the adjusting rod 3522, thus preventing the bristles 100 from bending.

[0132] Furthermore, the two limiting plates 3523 are combined into one group, and the two corresponding guide grooves 35231 form a guide space for the brush bristles. Several groups are installed along the circumferential direction of the outer ring of the adjusting rod 3522, and the guide grooves 35231 are installed corresponding to the receiving grooves 35221.

[0133] The limiting rod 3524 is I-shaped and is located in the limiting hole 35232, which connects several sets of limiting plates 3523 through it so that they fit tightly together; one end of the limiting rod 3524 is connected to the fixing sleeve 3521.

[0134] It should be noted that the limiting rod 3524 connects the limiting plate 3523 to the fixing sleeve 3521. The telescopic rotary cylinder 351 drives the adjusting rod 3522 to rotate within the limiting plate 3523, thereby causing the bristles 100 to retract tangentially into the receiving groove 35221 through the guide groove 35231, shortening the protruding part of the brush. Conversely, the telescopic rotary cylinder 351 rotates in the opposite direction, lengthening the protruding part of the brush. Thus, the length of the bristles 100 can be adjusted by the telescopic rotary cylinder 351, making it suitable for different working conditions, especially for ultra-high pressure valves. For cleaning narrow spaces that are difficult to clean, such as the gap between the valve plate and the ultra-high pressure valve when the valve is in the detection state, the brush 100 at one end of the adjusting rod 3522 can be used for cleaning. For example, when the ultra-high pressure valve is in the cleaning state, the gap between the valve plate and the ultra-high pressure valve can be adjusted by rotating the telescopic rotary cylinder 351 to extend the brush 100 into the gap, and then the telescopic rotary cylinder 351 can extend and retract to make it brush back and forth in the gap, thereby cleaning the ultra-high pressure valve.

[0137] Camera mounting base 41, which is fixedly mounted on angle adjustment component 33;

[0138] Camera 200, which is fixedly mounted on a mounting base.

[0139] It should be noted that the observation component 4 is used to observe the surface cleaning status of the ultra-high pressure valve by rotating one revolution with the rotating roller 31 after the cleaning component 3 has completed cleaning. Due to the high pressure test, close observation by the operator is avoided.

[0145] Furthermore, the water pipe 53 is made of a flexible material.

[0146] It should be noted that during the online testing of the ultra-high pressure valve, the medium containing impurities is returned to the water tank 51 after passing through the ultra-high pressure valve to achieve circulation.

The second fixing seat 721 has a "convex" track groove 7213 and has two sets correspondingly.

[0155] The second guide rod 722 is used to guide the displacement of the second fixed seat 721. It is fixed on the second fixed seat 721 and there are two sets of it.

[0156] The fixing plate 723 has an arc-shaped upper end with the arc size corresponding to the outer diameter of the ultra-high pressure valve. The fixing plate 723 is mounted on the second fixing seat 721 and has two sets of corresponding fixing plates.

[0157] The fourth drive assembly 724 is connected to the second fixed seat 7211 for pressing, and drives it to move vertically reciprocally to press the ultra-high pressure valve. The fourth drive assembly 724 preferably adopts a screw jack.

[0158] It should be noted that the second positioning fixing seat 7212 is used to position the clamping position of the ultra-high pressure valve so that it is concentric with the central push rod 22 to avoid collision. The second positioning fixing seat 7212 is fixedly set.

[0159] It should be noted that the pressing second fixing seat 7211 is moved vertically by the fourth drive assembly 724 in conjunction with the guide rod, thereby pressing and fixing the ultra-high pressure valve.

[0160] As an improvement, the axial clamping assembly 73 includes:

[0161] The clamping rod 731 has threads at both ends, one set of which is positive and the other set of which is negative. It passes through the track groove 7213 and its center position is rotatably mounted on the second fixed seat 721.

The two sets of fixing plates 723 move towards each other and are tightly connected to the ultra-high pressure valve, so that it is axially fixed and locked.

[0166] Work steps

[0167] Step 1: Turn on the water pump and pass the medium containing impurities in the water tank through the water pipe to the ultra-high pressure valve. Repeatedly open and close the ultra-high pressure valve through the control panel.

[0168] Step 2: Close the ultra-high pressure valve, remove the push rod at one end, and use the angle adjustment component in the cleaning assembly to move the cleaning component and the water spraying component to the position of the ultra-high pressure valve sealing ring. Clean the ultra-high pressure valve on one side. The water spraying component is set with a rotary cylinder to make the water spraying component rotate and spray water, so as to achieve cleaning of the ultra-high pressure valve over a wider area. The cleaning component is set with a telescopic rotary electric cylinder to make it reciprocate and rotate to achieve cleaning. The water spraying component and the cleaning component are alternately set along the circumference of the rotating roller to clean the ultra-high pressure valve.

[0169] Step 3: Connect the limiting plate to the fixed sleeve using the limiting rod. The telescopic rotary cylinder drives the adjusting rod to rotate within the limiting plate, causing the bristles to move tangentially through the guide groove. This adjusts the bristle extension length, making it suitable for cleaning narrow spaces in ultra-high pressure valves that are difficult to clean under different working conditions. For example, when the ultra-high pressure valve is in the detection state, the gap between the valve plate and the valve is closed and can be cleaned using the bristles at one end of the adjusting rod. Similarly, when the ultra-high pressure valve is in the cleaning state, the gap between the valve plate and the valve is closed and can be cleaned by adjusting the bristle extension length using the telescopic rotary cylinder, allowing it to reach into the gap. The telescopic rotary cylinder then extends and retracts, causing the bristles to brush repeatedly in the gap, thus cleaning the ultra-high pressure valve.

[0170] Step 4: Drive the rack and pinion to reciprocate on the slide rail slider assembly via the third drive component, thereby driving the rotation of the adjusting roller so that the angle adjusting component can adjust the angle and remotely observe the sealing performance of the ultra-high pressure valve after testing.

[0171] Step 5: After completing the test, remove the push rods at both ends, clean both ends of the ultra-high pressure valve using the cleaning assembly, and observe whether it is clean using the observation assembly.

[0172] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
