Description

Technical Field

[0001] This utility model relates to the technical field of shut-off valve structure, specifically a hydraulic emergency shut-off valve. Background Technology

[0002] Hydraulic emergency shut-off valves play an important role in many key fields such as chemical industry, power industry and manufacturing industry. With their high reliability and safety characteristics, they have become an indispensable piece of equipment in industrial safety. However, there are still some shortcomings in the actual use of hydraulic emergency shut-off valves.

[0003] Hydraulic emergency shut-off valves often cannot intelligently determine the shut-off response. They generally lack integrated pressure and temperature sensing structures, making it difficult to perform timely and accurate shut-off protection operations through efficient monitoring. Furthermore, the hydraulic structure of such valves is usually located at the top of the valve body, and hydraulic oil can easily leak onto the valve body during hydraulic movement, causing contamination. Therefore, we propose a new type of hydraulic emergency shut-off valve. Utility Model Content

A valve cover is installed on the top of the valve body, and an assembly outlet and an assembly inlet are respectively provided at both ends of the valve body. The hydraulic telescopic cylinder is installed on one side of the valve body, and a control box is fixed at one end of the hydraulic telescopic cylinder. A wireless signal transceiver module, a power supply module, and a microcontroller are sequentially installed inside the control box. A piston rod is provided at the output end of the hydraulic telescopic cylinder. A valve rod is slidably connected to the top of the valve cover. A drive block connected to the piston rod is welded to the top of the valve rod, and a shut-off valve core is welded to the bottom of the valve rod. A shut-off cavity matching the shut-off valve core is provided inside the valve body. A pressure sensor and a temperature sensor are respectively installed on the outer wall of the shut-off valve core.

[0006] Preferably, a positioning pin that engages with the valve body is uniformly welded to the bottom edge of the valve cover, and a screw is provided between the positioning pin and the valve body.

[0007] Preferably, the bottom of the valve cover and the top of the valve body are both vulcanized with a rubber sealing layer.

[0008] Preferably, the edges of both the assembly outlet and the assembly inlet are uniformly provided with fixing screw holes arranged at equal angles.

[0009] Preferably, both the assembly outlet and the assembly inlet are fixed with silicone rubber sealing rings at the ends furthest from the valve body.

[0010] Preferably, the piston rod is disposed on the top of the hydraulic telescopic cylinder, and the hydraulic telescopic cylinder is arranged vertically.

[0011] Preferably, both ends of the bottom of the drive block are provided with limit slide rods, and the valve cover is provided with a limit slide cavity that matches the limit slide rod. A spring is connected between the limit slide rod and the limit slide cavity so that it can limit and guide the valve stem during the lifting and lowering movement.

[0012] Preferably, the piston rod has a connecting arm welded to the top, which is connected to the drive block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The hydraulic emergency shut-off valve optimizes its performance by installing a shut-off valve core, etc. The pressure sensor and temperature sensor can monitor the temperature and pressure of the medium passing through the valve body in real time and send the monitored data to the microcontroller electrically connected through the internal wiring of the valve stem. After the microcontroller calculates and analyzes, the microcontroller will intelligently control the hydraulic telescopic cylinder to drive the piston rod to telescopic movement according to the preset program. This can control the valve stem to drive the shut-off valve core to move up and down, realize the shut-off valve core to shut off or open the shut-off passage, and thus enable the device to realize real-time monitoring function by integrating pressure and temperature sensing structure, meeting the needs of intelligent, efficient and automatic shut-off. In addition, the wireless signal transceiver module can send the abnormal data to the back-end terminal through wireless communication technology when the device shuts off in an emergency due to abnormal pressure and temperature, so that the staff can handle it in time. This enables the device to realize remote monitoring and automatic control by adopting intelligent control, and improves the intelligence level of the device.

[0015] (2) The hydraulic emergency shut-off valve optimizes its structure by installing a valve body, etc. On the one hand, by fixing the hydraulic telescopic cylinder vertically upward on the back side of the valve body and connecting the upward-extending piston rod to the top of the valve stem, this drive structure, compared with the common structure where the hydraulic port is set downward on the shut-off valve, ensures that the hydraulic oil will not leak downward into the valve body and cause contamination during the hydraulic telescopic movement, thereby optimizing the use effect of the hydraulic emergency shut-off valve. On the other hand, by setting limit slide rods at both ends of the bottom of the drive block, setting a limit slide cavity on the valve cover that is slidably connected to the limit slide rod, and connecting a spring between the limit slide rod and the limit slide cavity, these two sets of sliding guide structures can limit and guide the valve stem during the lifting and lowering movement, and improve the smooth anti-lateral deviation effect when the valve stem drives the shut-off valve core to move.

[0027] In use, the hydraulic telescopic cylinder 7 is fixed vertically upward on the back side of the valve body 6, and the upward-extending piston rod 11 is connected to the top of the valve rod 8. Compared with the common structure where the hydraulic port is set downward on the shut-off valve, this drive structure ensures that the hydraulic oil will not leak downward into the valve body 6 and cause contamination during the hydraulic telescopic movement, thereby optimizing the use effect of the hydraulic emergency shut-off valve.

[0028] A shut-off valve core 13 is welded to the bottom of the valve stem 8, and a shut-off passage cavity 15 matching the shut-off valve core 13 is provided inside the valve body 6;

[0029] A pressure sensor 14 and a temperature sensor 18 are respectively installed on the outer wall of the shut-off valve core 13;

[0030] In use, the pressure sensor 14 and temperature sensor 18 can monitor the temperature and pressure of the medium passing through the valve body 6 in real time, and send the monitored data to the microcontroller 23 electrically connected through the internal wiring of the valve stem 8. After calculation and analysis by the microcontroller 23, the microcontroller 23 will intelligently control the hydraulic telescopic cylinder 7 to drive the piston rod 11 to telescopic movement according to the preset program. This can control the valve stem 8 to drive the shut-off valve core 13 to move up and down, so as to realize the shut-off valve core 13 to shut off or open the shut-off passage 15. Thus, the device achieves real-time monitoring function by integrating pressure and temperature sensing structure, which meets the needs of intelligent, efficient and automatic shut-off. Furthermore, the wireless signal transceiver module 19 can send the abnormal data to the back-end terminal through wireless communication technology when the device shuts off in an emergency due to abnormal pressure and temperature, so as to facilitate timely handling by the staff. This makes the device adopt intelligent control to realize remote monitoring and automatic control, and improve the intelligence level of the device.

[0031] The bottom edge of the valve cover 3 is uniformly welded with positioning pins 21 that engage with the valve body 6, and screws are provided between the positioning pins 21 and the valve body 6.

[0032] The bottom of valve cover 3 and the top of valve body 6 are both vulcanized with rubber sealing layers.

[0033] Fixing screw holes 17 are evenly arranged at equal angles at the edges of assembly outlet 4 and assembly inlet 5.

[0034] Both the assembly outlet 4 and the assembly inlet 5, at the end furthest from the valve body 6, are fixed with silicone rubber sealing rings 16.

[0035] Both ends of the bottom of the drive block 10 are provided with limit slide rods 1, and the valve cover 3 is provided with a limit slide cavity 20 that matches the limit slide rod 1. A spring 2 is connected between the limit slide rod 1 and the limit slide cavity 20 so that it can limit and guide the valve rod 8 in the lifting and lowering movement.

[0036] A connecting arm 9, which is connected to the drive block 10, is welded to the top of the piston rod 11.

[0037] In this embodiment, the user first uses the fixing screw holes 17 and silicone rubber sealing rings 16 on the assembly outlet 4 and assembly inlet 5 to connect the valve body 6 to the external pipeline using screws. Then, the device is connected to an external power supply via the wires on the control box 12. In actual operation, the pressure sensor 14 and temperature sensor 18 can monitor the temperature and pressure of the medium passing through the valve body 6 in real time and send the monitored data to the microcontroller 23 electrically connected via the internal wiring of the valve stem 8. After calculation and analysis by the microcontroller 23, the microcontroller 23 will intelligently control the hydraulic telescopic cylinder 7 to drive the piston rod 11 to telescopic movement according to the preset program. This can control the valve stem 8 to drive the shut-off valve core 13 to move up and down, realizing the shut-off valve core 13 to shut off or open the shut-off passage 15. Thus, the device, through the integrated pressure and temperature sensing structure, realizes real-time monitoring function, meeting the needs of intelligent, efficient and automatic shut-off. Furthermore, the wireless signal transceiver module 19 can be used to transmit the device's pressure and temperature data. In case of an emergency shutdown due to an anomaly, the abnormal data is transmitted to the back-end terminal via wireless communication technology, facilitating timely handling by staff. This enables the device to adopt intelligent control, achieving remote monitoring and automatic control, thus improving the device's intelligence level. Simultaneously, by fixing the hydraulic telescopic cylinder 7 vertically upward on the back side of the valve body 6 and connecting the upward-extending piston rod 11 to the top of the valve rod 8, this drive structure, compared to the common structure where the hydraulic port is positioned downward on the shut-off valve, ensures that hydraulic oil will not leak downward into the valve body 6 and cause contamination during hydraulic telescopic movement, thereby optimizing the performance of the hydraulic emergency shut-off valve. Furthermore, by setting limit slide rods 1 at both ends of the bottom of the drive block 10, and setting a limit slide cavity 20 on the valve cover 3 that slides and connects to the limit slide rods 1, and connecting a spring 2 between the limit slide rods 1 and the limit slide cavity 20, these two sets of sliding guide structures can limit and guide the valve rod 8 during its lifting and lowering movement, improving the smoothness and anti-lateral deviation effect when the valve rod 8 drives the shut-off valve core 13.
