Technical Field

[0001] The utility model relates to the technical field of valve body testing, in particular to a high-pressure valve tool with a sealing test function. Background Art

[0002] A high-pressure valve body is a component used to control high-pressure fluids. Structurally, it's typically constructed from sturdy metal to withstand the immense pressures of high-pressure environments. It typically has a specific shape and dimensions, including fluid passages, sealing surfaces, and connection ports. The fluid passages are carefully designed to ensure smooth flow under high pressure. The sealing surfaces are precision-machined to prevent leakage even under high pressure. The connection ports are used to connect to pipelines or other equipment.

[0003] In the prior art, after the high-pressure valve is assembled, it needs to be removed from the assembly tool and then installed on the test tool for sealing testing, which easily increases the risk of damage to the valve body during movement, resulting in errors in the sealing test results. At the same time, the number of steps to complete the work is increased, which will make the valve body production process cumbersome. Therefore, the present application provides a high-pressure valve tool with a sealing test function to meet the needs. Utility Model Content

[0026] like Figures 1 to 2 As shown, the fixing assembly includes: two groups of support platforms 2, which are respectively installed at the two groups of workstations that are farthest apart from each other on the assembly tool 1; a fixing rod 3, both ends of which are rotatably connected to a group of support platforms 2, for installing the test part; a driving part 4, which is installed on the support platform 2 and is used to drive the fixing rod 3 to rotate; the driving part 4 adopts a driving motor, and the output end of the driving motor is connected to the fixing rod 3, and the driving motor is fixed through a support frame.

[0027] like Figures 1 to 5 As shown, the test part includes: two groups of right-angle blocks 5, each group of right-angle blocks 5 is connected to a group of fixed rods 3, and is configured so that when the fixed rods 3 rotate, the right-angle blocks 5 rotate accordingly, so that the two groups of right-angle blocks 5 jointly close or open all the openings of the valve body; a snap assembly is located on the two groups of right-angle blocks 5, and is configured so that when the two groups of right-angle blocks 5 jointly close all the openings of the valve body, the snap assembly keeps the two groups of right-angle blocks 5 fixed; a gas supply assembly 6 is installed on one group of right-angle blocks 5, and is used to input gas into the valve body when the right-angle blocks 5 close all the openings of the valve body; an exhaust pipe 7 is installed on the other group of right-angle blocks 5, and is used to discharge the gas in the valve body; two groups of high-precision air pressure detectors 8, respectively installed on the gas supply assembly 6 and the exhaust pipe 7, and are used to detect the air pressure when the gas passes through; the gas supply assembly 6 includes a gas supply valve, an air duct and a gas storage tank (the air duct and the gas storage tank are not shown), which is used to supply external gas to the valve body.

[0028] Example 2: Figure 4 and Figure 5As shown, the snap assembly includes: a slot 9, which is provided on a group of right-angle blocks 5; an insert block 10, which is installed on another group of right-angle blocks 5 and is configured to engage with the insert block 10 and the slot 9; two groups of grooves 11, respectively provided on both sides of the slot 9; multiple groups of elastic members 12, respectively installed in the two groups of grooves 11; two groups of card blocks 13, each group of grooves 11 is slidably connected with a group of card blocks 13, and the two groups of card blocks 13 are respectively connected to the elastic members 12 in the corresponding grooves 11, and are configured to limit the top of the insert block 10 after the insert block 10 is engaged with the slot 9 to prevent the insert block 10 from being dislocated; the elastic member 12 is an elastic object such as a spring or rubber.

[0029] like Figure 3 As shown, the right-angle block 5 includes: a right-angle area 14 for being exposed relative to the valve body; and a rotation area 15 located on one side of the right-angle area 14 and rotatably connected to the fixing rod 3 .

[0030] like Figures 1 to 2 As shown, it also includes: multiple groups of limit rings 16, evenly installed on the fixed rod 3, and each group of limit rings 16 is arranged to be installed between two groups of workstations of the assembly tool 1, so that the rotation area 15 of the right-angle block 5 is aligned with the valve body assembly workstation.

[0031] The top ends of the two groups of clamping blocks 13 are both inclined, and the inclination direction points to the central axis direction of the slot 9, so that when the inserting block 10 enters the slot 9 downward, the clamping blocks 13 move into the groove 11.

The card block 13 is squeezed and the card block 13 squeezes the elastic member 12, causing the card block 13 to move into the groove 11. When the plug 10 is completely inserted into the slot 9, the card block 13 pops out under the action of the elastic member 12, limiting the top end of the plug 10 to prevent the plug 10 from dislocating. At this time, the two groups of right-angle blocks 5 jointly close all the openings of the valve body to achieve sealing of the valve body; then a sealing test is performed, and high-pressure gas is input into the valve body through the gas delivery assembly 6 installed on one group of right-angle blocks 5. At the same time, the exhaust pipe 7 installed on the other group of right-angle blocks 5 is used to discharge the gas in the valve body to ensure gas circulation. During the testing phase, the exhaust valve is closed, and two groups of high-precision air pressure detectors 8 installed on the gas delivery assembly 6 and the exhaust pipe 7 detect the air pressure of the passing gas. By detecting the air pressure change when the gas passes through, it can be judged whether the sealing of the valve body is good. After the test is completed, if it is necessary to discharge the gas in the valve body, the exhaust valve installed in the exhaust pipe 7 can be opened to control the discharge of the gas in the valve body.

[0035] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details.
