[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a direct-flow ultra-high pressure stop valve of the present invention comprises a first protective pressure relief regulating body 1, a stop valve body 2 and a second protective pressure relief regulating body 3, wherein the first protective pressure relief regulating body 1 is arranged at one end of the stop valve body 2, and the second protective pressure relief regulating body 3 is arranged at the other end of the stop valve body 2, the stop valve body 2 comprises a pressure sensor 4, a screw control wheel 5, a valve body 6, a delivery connecting pipe 7, a connecting flange 8, a threaded rotating control rod 9, an extrusion sealing disc 10 and an extrusion sealing plug 12, and the delivery connecting pipe 7 is fixedly connected to both ends of the valve body 6, The connecting flange 8 is fixedly connected to the end of the conveying connecting pipe 7 away from the valve body 6, the threaded rotating control rod 9 is rotatably arranged in the middle of the valve body 6, the screw control wheel 5 is fixedly connected to the upper end of the threaded rotating control rod 9, the extrusion sealing disk 10 is fixedly connected to the bottom end of the threaded rotating control rod 9, the extrusion sealing plug 12 is fixedly connected to the middle of the bottom end of the extrusion sealing disk 10, and the extrusion sealing disk 10 and the extrusion sealing plug 12 are arranged inside the valve body 6, and the conveying butt joint 14 in the first protective pressure relief regulating body 1 and the second protective pressure relief regulating body 3 can be connected to the conveying The pipe body is connected so that the high-pressure medium to be transported can be controlled by the valve body. During the transportation process, the medium with high speed and high pressure flows into the interior of the buffer pressure relief frame 19 through the transportation butt joint 14, and then flows into the transportation connecting pipe 7 and the valve body 6. By screwing the control wheel 5, the threaded rotation control rod 9 is threadedly rotated on the valve body 6 to press and push the extrusion sealing disk 10 and the extrusion sealing plug 12 downward. The downwardly moving extrusion sealing plug 12 seals and blocks the transportation slot hole set in the valve body 6, so that the flow and transportation of the transported medium stops, so that the present invention can be used for the production of high-pressure medium. The valve body is convenient for controlling and intercepting the flowing medium. A rubber sealing ring 11 is fixedly provided at the bottom end of the extrusion sealing disk 10 and at the upper end of the extrusion sealing plug 12. The bottom edge of the extrusion sealing plug 12 is arranged in a smooth arc shape, so that the medium with high flow rate will not quickly wear the extrusion sealing plug 12, and the arranged rubber sealing ring 11 fully plays a sealing role. The first protective pressure relief regulating body 1 and the second protective pressure relief regulating body 3 have the same structure, and the first protective pressure relief regulating body 1 and the second protective pressure relief regulating body 3 are distributed in a mirror-symmetrical manner.

[0033] like Figure 6 and Figure 7As shown, the first protective pressure relief regulating body 1 and the second protective pressure relief regulating body 3 both include a conveying butt joint pipe 14, a support bracket 15, an adjustment control unit 18, a buffer pressure relief frame 19 and a connecting and fixing pipe body 20. The support bracket 15 is symmetrically fixedly installed at the bottom end of the buffer pressure relief frame 19, the conveying butt joint pipe 14 is fixedly connected to the middle of the outer end of the buffer pressure relief frame 19 by bolts, the connecting and fixing pipe body 20 is fixedly connected to the middle of the inner end of the buffer pressure relief frame 19 by bolts, and the adjustment control unit 18 is arranged at the four end corners of the buffer pressure relief frame 19. The arranged adjustment control unit 18 can assist in indirectly controlling and adjusting the buffer adjustment space inside the buffer pressure relief frame 19.

[0034] The buffer pressure relief frame 19 is arranged in a cross shape, and a fixed support plate is arranged at the bottom end of the support bracket 15 to play the role of fixed support erection.

[0035] The outer end of the buffer pressure relief frame 19 is fixedly installed with a fixed connecting disk 17 through the outer end, and the outer end of the fixed connecting disk 17 is fixedly connected to the first solenoid valve 16, and the outer end of the first solenoid valve 16 is fixedly connected to the discharge delivery hose 13. The high-pressure and high-flow rate medium enters the buffer pressure relief frame 19 for buffering and is discharged outward along the discharge delivery hose 13 through the first solenoid valve 16 to achieve automatic pressure relief processing, which can fully protect the interior of the valve body.

[0036] A second solenoid valve 21 is evenly fixedly mounted on the side end of the buffer pressure relief frame 19 away from the fixed connection plate 17 through the solenoid valve body, which plays a role in assisting pressure relief regulation.

[0037] like Figure 8 As shown, the regulating control part 18 includes a sealing rubber ring 22, a sealing adjustment plate 23, a fixed mounting frame 24 and an electric push rod 25. The electric push rod 25 is fixedly mounted on the fixed mounting frame 24, the sealing adjustment plate 23 is fixedly connected to the front end of the electric push rod 25, and the sealing rubber ring 22 is evenly fixed on the sealing adjustment plate 23. After the electric push rod 25 is started to drive the sealing adjustment plate 23 to fully slide outward along the buffer pressure relief frame 19, the high-pressure and high-flow rate medium enters the buffer pressure relief frame 19 and is buffered inside, and then is discharged outward along the discharge delivery hose 13 through the first solenoid valve 16 to realize automatic pressure relief processing, which can fully protect the interior of the valve body, so that the valve body can safely and stably intercept the high-pressure medium, and the side end of the buffer pressure relief frame 19 is assisted by a second solenoid valve 21. After the sealing cover of the second solenoid valve 21 is removed and intercepted with the discharge delivery hose 13, it can also play a role in auxiliary pressure relief regulation, so that the pressure relief ability of the valve body is stronger, and it is safe and stable when conveying ultra-high pressure and high flow rate media.

[0038] The fixed mounting frame 24 is fixedly mounted on the outside of the end of the buffer pressure relief frame 19, the sealing adjustment plate 23 is slidably clamped in the inside of the buffer pressure relief frame 19, the first solenoid valve 16 and the second solenoid valve 21 are both arranged at the inner side of the end of the buffer pressure relief frame 19, the connecting fixed pipe body 20 is fixedly connected to the connecting flange 8 by bolts, and the conveying connecting pipe 7 is connected to the inside of the buffer pressure relief frame 19, which can facilitate the conveying of high-speed flowing media.

[0039] The working principle of the first embodiment is as follows: the delivery butt joint 14 in the first protective pressure relief regulating body 1 and the second protective pressure relief regulating body 3 can be connected with the conveying pipe body, so that the conveyed high-pressure medium can be controlled by the valve body. During the conveying process, the medium with high speed and high pressure flows into the interior of the buffer pressure relief frame 19 through the delivery butt joint 14, and then flows into the conveying connecting pipe 7 and the valve body 6. By screwing the control wheel 5, the threaded rotation control rod 9 is threadedly rotated on the valve body 6 to press and push the extrusion sealing disk 10 and the extrusion sealing plug 12 downward. The conveying slot hole set in the valve body 6 is sealed and blocked by the downwardly moving extrusion sealing plug 12, so that the conveyed medium stops flowing and conveying, making it convenient for the valve body to control and intercept the flowing medium;

[0040] When a medium with a high flow rate is transported from the inside of the valve body or is blocked by the valve body, in order to prevent the discharge end from temporarily stopping the discharge so as to increase the pressure at the interception point of the valve body, the electric push rods 25 at various positions can be started at this time, and the sealing adjustment plate 23 can be driven by the electric push rods 25 to slide outward inside the buffer pressure relief frame 19, so that the cavity and space inside the buffer pressure relief frame 19 are increased, so that when the medium stops being discharged at the discharge terminal, the regulating valve body arranged in the transportation process will not be affected by the excessive extrusion pressure of the high-speed and high-pressure medium, and the extrusion fitting part between the inside of the valve body 6 and the extrusion sealing plug 12 and the rubber sealing ring 11 can be protected to prevent damage and leakage caused by excessive extrusion pressure, and four regulating control parts 18 can be set to the buffer space inside the buffer pressure relief frame 19 A wide range of adjustment is possible, and when the flow rate pressure of the conveyed medium increases during the conveying process, the electric push rod 25 is started to drive the sealing adjustment plate 23 to slide fully outward along the buffer pressure relief frame 19, so that the high-pressure and high-flow rate medium enters the buffer pressure relief frame 19 for buffering and is discharged outward along the discharge conveying hose 13 through the first solenoid valve 16 to realize automatic pressure relief processing, which can fully protect the interior of the valve body, so that the valve body can safely and stably intercept the high-pressure medium, and the side end of the buffer pressure relief frame 19 is auxiliaryly provided with a second solenoid valve 21. After the sealing cover of the second solenoid valve 21 is removed and intercepted with the discharge conveying hose 13, it can also play a role in auxiliary pressure relief regulation, so that the pressure relief ability of the valve body is stronger, and it is safe and stable when conveying ultra-high pressure and high-flow rate media.

[0041] Embodiment 2

[0042] Based on the first embodiment, Figure 3 As shown, pressure sensors 4 are fixedly installed on the delivery connecting pipes 7 connected to both ends of the valve body 6.

[0043] When implementing this embodiment, the pressure sensor 4 is set up to detect and monitor the extrusion pressure on both sides of the valve body 6 in real time. When it is detected that the pressure value inside the valve body 6 changes too much, the information detected by the pressure sensor 4 can be infinitely transmitted to the controller and information receiver set at the end of the electric push rod 25, so that the operation of the electric push rod 25 can be automatically adjusted and controlled, and the space for storing and caching pressure inside the buffer pressure relief frame 19 can be automatically and accurately controlled and adjusted in a timely manner, so that the instantaneous extrusion pressure can be automatically and accurately released, and the valve body will not be damaged by excessive pressure, thereby playing a role of automatic detection and timely and accurate adjustment.

[0044] In the direct-flow ultra-high-pressure stop valve of the present invention, when a medium with a high flow rate is transported from the inside of the valve body or blocked by the valve body, in order to prevent the discharge end from temporarily stopping the discharge so as to increase the pressure at the interception point of the valve body, the cavity and space inside the buffer pressure relief frame 19 can be adaptively adjusted and increased, so that when the medium stops being discharged at the discharge terminal, the regulating valve body arranged in the transportation process will not be affected by the excessive extrusion pressure of the high-speed and high-pressure medium, and the extrusion fitting part between the inside of the valve body 6 and the extrusion sealing plug 12 and the rubber sealing ring 11 can be protected to prevent damage and leakage caused by excessive extrusion pressure, and four regulating control parts 18 are provided, which can adjust the buffer space inside the buffer pressure relief frame 19 over a wide range, and when the transported medium is transported When the flow rate pressure increases during the delivery process, the electric push rod 25 is started to drive the sealing adjustment plate 23 to slide fully outward along the buffer pressure relief frame 19, so that the high-pressure and high-flow rate medium enters the buffer pressure relief frame 19 for buffering and is discharged outward along the discharge delivery hose 13 through the first solenoid valve 16 to realize automatic pressure relief processing, which can fully protect the interior of the valve body, so that the valve body can safely and stably intercept the high-pressure medium, and the side end of the buffer pressure relief frame 19 is auxiliaryly provided with a second solenoid valve 21. After the sealing cover of the second solenoid valve 21 is removed and intercepted with the discharge delivery hose 13, it can also play a role in auxiliary pressure relief regulation, so that the pressure relief ability of the valve body is stronger, and it is safe and stable when transporting ultra-high pressure and high flow rate media.
