Description

Technical Field

[0001] This utility model relates to the field of shut-off valve technology, and in particular to a shut-off valve with heat dissipation function. Background Technology

[0002] A gate valve is a type of valve used to control the flow of fluid, also known as a check valve. It can be used to open or close the fluid in a pipeline, or to regulate the flow rate of the fluid. Gate valves are commonly used in applications requiring frequent switching and strict control of fluid flow, and are widely used in petrochemical, power, metallurgical, chemical, shipbuilding, water treatment, water supply, and drainage industries.

[0003] In daily use, common gate valves typically use fans and cooling water circulation to dissipate heat. However, this method usually requires additional power to drive the fan and the water flow, which can easily increase the overall cost of the device.

[0004] Therefore, this utility model provides a shut-off valve with heat dissipation function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shut-off valve with heat dissipation function. As the fluid flows inside the shut-off valve, the turbine fan can rotate, thereby dissipating the heat inside the shut-off valve to the outside, effectively improving the heat dissipation effect. No additional power is required, which helps to save energy costs.

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

[0007] A shut-off valve with heat dissipation function includes a valve body, a valve seat fixedly disposed at the middle position of the upper end face of the valve body, a top seat fixedly disposed at the upper end face of the valve seat, and an inlet cavity and an outlet cavity respectively opened on the front and rear sides of the valve body. A venting chamber is opened in the valve body near the upper side of the outlet cavity, and a rotating sleeve is inserted through the valve body near the center of the top surface of the outlet cavity, with the upper end of the rotating sleeve leading to the interior of the venting chamber.

[0008] A turbine fan is fixedly fitted on the upper periphery of the rotating sleeve near the interior of the ventilation chamber, and a turbine is fixedly fitted on the lower periphery of the rotating sleeve near the interior of the liquid outlet cavity. An air inlet strip hole is opened through the front and rear end faces of the top seat, and an air outlet strip hole is opened through the valve body on both sides near the middle of the ventilation chamber.

[0009] Through the above technical solution, the fluid flowing inside the liquid inlet cavity and the liquid outlet cavity drives the turbine to rotate, which in turn drives the turbine fan inside the ventilation chamber to rotate through the rotating sleeve. The rotation of the turbine fan drives the outside gas to enter the ventilation chamber from the air inlet hole and then flow out of the ventilation chamber through the air outlet hole, thereby blowing air to cool the valve body.

[0010] Furthermore, multiple ventilation channels are provided through the front and rear sides of the top seat, valve seat, and valve body, and the multiple ventilation channels are respectively arranged between the air inlet hole and the ventilation chamber;

[0011] Through the above technical solution, the ventilation channel can increase the connection between the ventilation chamber and the top seat, valve seat and valve body, which facilitates the circulation of gas in the ventilation chamber between the top seat, valve seat and valve body, thereby facilitating the cooling of the device.

[0012] Furthermore, a threaded rod is threadedly sleeved at the center of the top seat, and a lifting rod is slidably sleeved at the center of the valve seat. The lifting rod is sleeved on the lower end of the threaded rod, and the lower end of the lifting rod extends into the liquid outlet cavity. A plug is fixedly installed at the lower end of the lifting rod. A flow-blocking hole is opened inside the valve body near the center of the valve body between the liquid inlet cavity and the liquid outlet cavity.

[0013] By rotating the threaded rod, the lower end of the lifting rod moves downward, causing the plug fixed at the lower end of the lifting rod to embed into the flow-blocking hole, thereby cutting off the fluid.

[0014] Furthermore, a sealing bearing is fixedly sleeved inside the valve body near the middle of the rotating sleeve, and a sleeve joint is fixedly installed inside the valve body near the center of the top surface of the venting chamber. A rotating bearing is fixedly sleeved outside the sleeve joint, and the rotating bearing is fixedly sleeved at the upper end of the rotating sleeve.

[0015] The above technical solution enables the rotating sleeve to rotate smoothly inside the valve body.

[0016] Furthermore, a sealing chamber is provided inside the valve body near the rear side of the venting chamber, the venting chamber and the sealing chamber are connected, and a sealing bolt is threaded inside the sealing chamber;

[0017] The above technical solution allows the ventilation chamber to be opened by unscrewing the sealing bolts, which facilitates maintenance.

[0018] Furthermore, a rocker wheel is fixedly provided at the upper end of the threaded rod;

[0019] The above technical solution makes it easy for workers to rotate the rocker wheel to drive the threaded rod to rotate.

[0020] This utility model has the following beneficial effects:

[0021] This invention proposes a shut-off valve with heat dissipation function. It comprises an inlet cavity, an outlet cavity, a venting chamber, a rotating sleeve, a turbine, a vortex, an inlet slot, and an outlet slot. When fluid flows normally through the inlet and outlet cavities, the flow drives the turbine to rotate, which in turn drives the turbine to rotate. The turbine's rotation causes the gas in the venting chamber to flow, allowing the gas to enter through the inlet slot and exit through the outlet slot. This gas flow effectively dissipates heat from inside the shut-off valve to the outside, significantly improving heat dissipation without requiring additional power, thus saving energy costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] Reference Figure 1-6 An embodiment of this utility model provides a shut-off valve with heat dissipation function, including a valve body 1, a valve seat 2 fixedly disposed at the middle position of the upper end face of the valve body 1, a top seat 3 fixedly disposed at the upper end face of the valve seat 2, an inlet cavity 11 and an outlet cavity 12 respectively opened on the front and rear sides of the valve body 1, a venting chamber 16 opened on the upper side of the outlet cavity 12 inside the valve body 1, a rotating sleeve 21 is inserted through the valve body 1 near the center of the top surface of the outlet cavity 12, the upper end of the rotating sleeve 21 extends into the venting chamber 16, and multiple venting channels 7 are inserted through the top seat 3, the valve seat 2 and the front and rear sides of the valve body 1, and the multiple venting channels 7 are respectively disposed between the air inlet hole 9 and the venting chamber 16;

[0033] Ventilation channel 7 can increase the connection between ventilation chamber 16 and top seat 3, valve seat 2 and valve body 1, which facilitates the circulation of gas in ventilation chamber 16 between top seat 3, valve seat 2 and valve body 1, thereby facilitating the cooling of the device and increasing the heat dissipation effect.

[0034] A turbine 19 is fixedly fitted on the upper circumference of the rotating sleeve 21 near the inside of the venting chamber 16, and a turbine 22 is fixedly fitted on the lower circumference of the rotating sleeve 21 near the inside of the liquid outlet cavity 12. An air inlet hole 9 is opened through the front and rear end faces of the top seat 3, and an air outlet hole 8 is opened through the valve body 1 on both sides near the middle of the venting chamber 16.

[0035] The fluid flowing inside the liquid inlet cavity 11 and the liquid outlet cavity 12 drives the turbine 22 to rotate. The rotating sleeve 21 drives the turbine fan 19 inside the ventilation chamber 16 to rotate. The rotation of the turbine fan 19 drives the outside gas to enter the ventilation chamber 16 from the air inlet hole 9 and then flow out of the ventilation chamber 16 through the air outlet hole 8, thereby blowing air to cool the valve body 1.

[0036] A threaded rod 5 is threadedly fitted at the center of the top seat 3. A rocker wheel 4 is fixedly installed at the upper end of the threaded rod 5. A lifting rod 6 is slidably fitted at the center of the valve seat 2. The lifting rod 6 is fitted at the lower end of the threaded rod 5. The lower end of the lifting rod 6 leads to the inside of the liquid outlet cavity 12. A plug 14 is fixedly installed at the lower end of the lifting rod 6. A flow-blocking hole 13 is opened inside the valve body 1 near the center of the valve body 1, between the liquid inlet cavity 11 and the liquid outlet cavity 12.

[0037] By rotating the rocker wheel 4, the threaded rod 5 can be driven to rotate. By rotating the threaded rod 5, the lifting rod 6 sleeved at the lower end moves downward, so that the plug 14 fixed at the lower end of the lifting rod 6 is embedded in the flow-blocking hole 13 to cut off the fluid.

[0038] A sealing bearing 20 is fixedly fitted inside the valve body 1 near the middle position of the rotating sleeve 21. A sleeve joint 17 is fixedly fitted inside the valve body 1 near the center of the top surface of the venting chamber 16. A rotating bearing 18 is fixedly fitted outside the sleeve joint 17. The rotating bearing 18 is fixedly fitted inside the upper end of the rotating sleeve 21, so that the rotating sleeve 21 can rotate smoothly inside the valve body 1.

[0039] A sealing chamber 15 is provided inside the valve body 1 near the rear side of the venting chamber 16. The venting chamber 16 and the sealing chamber 15 are connected. A sealing bolt 10 is threaded inside the sealing chamber 15. By unscrewing the sealing bolt 10, the venting chamber 16 is opened, which is convenient for maintenance.

[0040] Working principle: Rotating the rocker wheel 4 facilitates the rotation of the threaded rod 5, thereby causing the lifting rod 6, which is sleeved at the lower end, to move up and down. This allows the plug 14, fixed at the lower end of the lifting rod 6, to be inserted into and removed from the flow obstruction hole 13, thus regulating the flow of fluid within the valve body 1. When the fluid flows normally within the inlet cavity 11 and outlet cavity 12 of the valve body 1, it drives the turbine 22 to rotate, thereby causing the rotating sleeve 21 to drive the turbine fan 19 inside the venting chamber 16 to rotate. When 19 rotates, it will drive the outside air into the ventilation chamber 16 from the air inlet hole 9. After passing through the ventilation channel 7, it will flow out of the ventilation chamber 16 through the air outlet hole 8. No additional power is required, so the valve body 1 can be cooled by blowing air. By setting the sealing bearing 20, the sleeve joint 17 and the rotating bearing 18, the rotating sleeve 21 can be rotated smoothly in the valve body 1. By rotating and unscrewing the sealing bolt 10, the sealing chamber 15 and the ventilation chamber 16 can be opened, which is convenient for device maintenance.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
