Description

Technical Field

[0001] This utility model belongs to the field of pressure testing equipment, specifically, it relates to a working pressure testing device for pressure valves. Background Technology

[0002] Valve pressure testing is an important step to ensure that valves can operate safely and reliably under normal working conditions.

[0003] Chinese patent with announcement number CN222280342U discloses a valve pressure testing fixture. A lifting mechanism is provided on the upper part of the base and a support plate is provided on the side of the lifting mechanism. A connecting rod is provided on the lower part of the support plate and a pressure head is provided on the lower part of the connecting rod. A placement plate is provided on the upper part of the base for placing and fixing the valve.

[0004] However, in the aforementioned valve pressure testing fixture, the telescopic rod of the pressure head is passively adjusted to press down and position the valve. When positioning large or small valves, the two ends of the valve cannot correspond to the plug, resulting in an inability to adapt to valves of different sizes and a low adaptability of the device.

[0005] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-3 As shown, this embodiment provides a working pressure detection device for pressure valves, including:

[0030] Support frame 1; a detection mechanism 2 is provided inside the support frame 1;

[0031] The positioning mechanism 3 includes two hydraulic push rods 301 respectively disposed on the top surface and bottom surface of the inner wall of the support frame 1, a transmission plate 302 disposed on the upper side of the hydraulic push rods 301, two top plates 303 slidably fitted on the upper side of the transmission plate 302, a driving mechanism 304 disposed on the upper side of the transmission plate 302 and used to drive the two top plates 303 to slide, and limiting rods 305 respectively disposed on opposite sides of the two top plates 303.

[0032] By placing the pressure valve between the two transmission plates 302 and aligning it with the plug 206, so that the operating end of the pressure valve faces the operator, the positioning mechanism 3 is activated. The hydraulic push rod 301 drives the transmission plate 302 to slide, so that the limit rod 305 is aligned with the mounting hole on the flange of the pressure valve. The drive mechanism 304 is activated to drive the top plate 303 and the limit rod 305 to slide, so that the limit rod 305 is inserted into the mounting hole on the flange of the pressure valve, and the top plate 303 holds the flange of the pressure valve in place, which is convenient for fixing pressure valves of different sizes.

[0033] Please see Figure 2 As shown, the transmission plate 302 in this embodiment is provided with a first T-shaped channel 306 on its upper side, and the top plate 303 is a T-shaped strip structure. The top plate 303 is slidably fitted in the first T-shaped channel 306, which facilitates the sliding of the top plate 303 through the first T-shaped channel 306 and improves the stability of the sliding of the top plate 303.

[0034] Please see Figure 1-2 As shown, the driving mechanism 304 in this embodiment includes a dual-axis extension motor 3041 disposed in the first T-shaped channel 306 and two threaded rods 3042 respectively disposed at both ends of the output shaft of the dual-axis extension motor 3041. The two threaded rods 3042 are threadedly engaged with the two top plates 303 respectively, and the thread directions of the two threaded rods 3042 are opposite. The support frame 1 has a U-shaped frame structure, which facilitates the sliding of the top plate 303 and the limiting rod 305 by driving the threaded rods 3042 through the dual-axis extension motor 3041.

[0035] To verify the pressure resistance of the pressure valve in both directions, please refer to [link / reference]. Figure 1-3 As shown, the detection mechanism 2 in this embodiment includes two sliding plates 201 slidably fitted within the support frame 1, multiple electric push rods 202 connected to the inner wall of the support frame 1 for driving the sliding plates 201 to slide, a high-pressure air pump 203 connected to one side of the sliding plates 201, and a pressure sensor 204 connected to the air outlet of the high-pressure air pump 203. A vent 205 is provided on one side of the sliding plate 201, and the vent 205 communicates with the air outlet of the high-pressure air pump 203. A plug 206 is provided on one side of the sliding plate 201, and the plug 206 communicates with the vent 205. The inner wall of the support frame 1... The upper and lower sides are provided with second guide channels 101. The upper and lower ends of the sliding plate 201 are T-shaped plate structures. The upper and lower ends of the sliding plate 201 are respectively slidably engaged in the two second guide channels 101. By opening the detection mechanism 2, the electric push rod 202 drives the sliding plate 201 to slide. The end of the pressure valve is blocked by the plug 206. One set of high-pressure air pumps 203 is turned on in conjunction with the pressure sensor 204 to facilitate unidirectional detection of the pressure valve bearing pressure. After the detection is completed, one set of high-pressure air pumps 203 is turned on in conjunction with the pressure sensor 204 to facilitate reverse detection of the pressure valve bearing pressure and bidirectional detection of the pressure valve bearing pressure.

[0036] Working principle: The pressure valve is placed between the two transmission plates 302 and aligned with the plug 206, with the operating end of the pressure valve facing the operator. The positioning mechanism 3 is activated, and the hydraulic push rod 301 drives the transmission plates 302 to slide, aligning the limit rod 305 with the mounting hole on the pressure valve's flange. The drive mechanism 304 is activated, and the dual-shaft extension motor 3041 drives the threaded rod 3042 to slide the top plate 303 and the limit rod 305, allowing the limit rod 305 to insert into the mounting hole on the pressure valve's flange without passing through it. The top plate 303 then holds the pressure valve's flange in place, facilitating the fixing of pressure valves of different sizes. The different sizes of pressure valves mentioned here refer to pressure valves with the same mounting hole specification, that is, pressure valves with different sizes of mounting holes corresponding to the limit rod 305. They are not all pressure valves. Then, the detection mechanism 2 is activated, and the electric push rod 202 drives the sliding plate 201 to slide, blocking the end of the pressure valve through the plug 206. One set of high-pressure air pumps 203 is activated in conjunction with the pressure sensor 204 to facilitate unidirectional detection of the pressure valve's pressure resistance. After the detection is completed, another set of high-pressure air pumps 203 is activated in conjunction with the pressure sensor 204 to facilitate reverse detection of the pressure valve's pressure resistance, thus facilitating bidirectional detection of the pressure valve's pressure resistance.

All electrical appliances in this utility model are powered by an external power source or a built-in battery. No restrictions are placed on the model or specific type of any electrical appliance in this utility model.
