Description

Technical Field

[0001] This invention relates to the field of valves, and more specifically to a high-sealing valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc., and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Shut-off valves are used for opening and closing and are commonly installed at the inlet and outlet of cold and heat sources, equipment inlet and outlet, and pipeline branches. They can also be used as drain valves and vent valves. The sealing performance of a valve refers to its ability to prevent media leakage at each sealing part; it is the most important technical performance indicator of a valve. There are three sealing parts in a valve: the contact point between the opening and closing element and the valve seat; the mating point between the packing and the valve stem and stuffing box; and the connection point between the valve body and the valve cover. Leakage at the first point is called internal leakage, which is commonly referred to as incomplete closure and will affect the valve's ability to cut off the medium. For shut-off valves, internal leakage is unacceptable. Leakage at the latter two points is called external leakage, which means the medium leaks from inside the valve to the outside. External leakage can cause material loss, environmental pollution, and even accidents in severe cases. Therefore, valves must have reliable sealing performance. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a high-sealing valve, which has the beneficial effect of preventing external leakage of the sealing valve.

[0004] A high-sealing valve includes a pump chamber, a one-way valve I, a one-way valve II, and a sealing disc. The pump chamber has an annular notch integrally formed on the upper side and an annular notch integrally formed on the left side. The one-way valve I is attached to the lower side of the annular notch on the upper side of the pump chamber, and the one-way valve II is nested to the left of the annular notch on the left side of the pump chamber. The sealing disc is slidably connected to the inside of the pump chamber through a sealing ring. The sealing disc is located below the one-way valve II, and the pump chamber is located inside the valve body.

[0005] It also includes a valve cover and a gasket. The pump chamber is welded to the lower side of the left part of the valve cover. The valve cover is fixed to the upper side of the valve body by bolts. A gasket is fixed between the valve cover and the valve body by bolts.

[0006] It also includes a filter screen, spring I, and a diaphragm. Spring I is welded to the upper side of check valve I and nested inside the annular notch on the upper side of the pump chamber. The filter screen is welded to the upper side of spring I, and multiple small holes are integrally formed on the filter screen at even intervals. The diaphragm is integrally formed on the left side of check valve II, and the diaphragm material is rubber.

[0007] It also includes a sealing rod and gear I. The sealing rod is welded to the right side of the sealing disc. The lower right part of the pump cavity has an integrally formed notch. The sealing rod passes through the lower right notch of the pump cavity. The right part of the valve body has an integrally formed groove. Gear I is rotatably connected to the groove of the right part of the valve body. The middle part of gear I has an integrally formed thread.

[0026] like Figure 2-3 As shown, this example can achieve the effect of preventing leakage from the sealed valve.

[0027] The high-sealing valve includes a pump chamber 107, a one-way valve I 102, a one-way valve II 105, and a sealing disc 109. The pump chamber 107 has an integrally formed annular notch on its upper side and an integrally formed annular notch on its left side. The one-way valve I 102 is fitted to the lower side of the circular notch on the upper side of the pump chamber 107. The one-way valve II 105 is nested to the left of the annular notch on the left side of the pump chamber 107. The sealing disc 109 is slidably connected inside the pump chamber 107 via a sealing ring. The sealing disc 109 is positioned below the one-way valve II 105, and the pump chamber 107 is located inside the valve body 304. The sealing disc 109 moves downwards, thereby... As the volume of pump chamber 107 increases, the air pressure inside pump chamber 107 increases, causing check valve I 102 to open while check valve II 105 closes. Check valve I 102 then draws air into pump chamber 107. After the air is drawn in, the sealing disc 109 moves upward, causing the volume of pump chamber 107 to decrease. This leads to an increase in air pressure inside pump chamber 107, causing check valve I 102 to close while check valve II 105 opens. Check valve II 105 then pumps air into valve body 304, increasing the air pressure inside valve body 304. This prevents water from entering valve body 304 and achieves the effect of preventing leakage from the sealed valve.

[0028] like Figure 10 As shown, this example can achieve the effect of further sealing the valve body 304.

[0029] The high-sealing valve includes a valve cover 101 and a gasket 302. The pump chamber 107 is welded to the lower side of the left part of the valve cover 101. The valve cover 101 is fixed to the upper side of the valve body 304 by bolts. A gasket 302 is fixed between the valve cover 101 and the valve body 304 by bolts. The gasket 302 is made of rubber. When the bolts fixing the valve cover 101 are tightened, the gasket 302 will undergo elastic deformation, thereby sealing the gap between the valve cover 101 and the valve body 304, and thus achieving the effect of further sealing the valve body 304.

[0030] like Figure 4-5 As shown, this example can achieve the effect of one-way opening of check valve I 102 and check valve II 105.

[0031] The high-sealing valve includes a filter screen 104, a spring I 103, and a diaphragm 106. Spring I 103 is welded to the upper side of check valve I and nested inside the annular notch on the upper side of pump chamber 107. Filter screen 104 is welded to the upper side of spring I 103, and multiple small holes are integrally formed on filter screen 104 at even intervals. Diaphragm 106 is integrally formed on the left side of check valve II 105, which is made of rubber. The multiple small holes on filter screen 104 can prevent debris from entering the check valve. The pressure on the lower side of check valve I102 is less than the pressure on the upper side, causing the check valve I102 to be pressed downwards, thus preventing it from becoming blocked. When the pressure on the lower side of check valve I102 is greater than the pressure on the upper side, the check valve I102 is pressed downwards, and since the upper side of check valve I102 is blocked by valve cover 101, this obstructs the one-way flow. Valve I 102 moves upward, thus achieving the one-way opening effect of check valve I 102; spring I 103 is in a stretched state when check valve I 102 is closed, thus spring I 103 exerts an upward pulling force on check valve I 102, and the pull force causes check valve I 102 to fit tightly against the lower side of valve cover 101; when check valve I 102 is open, spring I 103 is further stretched, thus exerting an upward pulling force on check valve I 102, thereby facilitating the reset of check valve I 102; check valve II 1 When the air pressure on the left side is less than or equal to the air pressure on the right side, the diaphragm 106 moves away from the left side of the one-way valve II 105, allowing free gas to enter and exit, thus achieving the effect of opening the one-way valve II 105; when the air pressure on the left side of the one-way valve II 105 is greater than the air pressure on the right side, the diaphragm 106 is pressed by the air pressure towards the left side of the one-way valve II 105, thus the diaphragm 106 adheres to the left side of the one-way valve II 105, thus preventing gas from entering, thus achieving the effect of closing the one-way valve II 105, thus achieving the effect of one-way opening the one-way valve II 105.

[0032] like Figure 3-8 As shown, this example can achieve the effect of the sealing disc 109 moving up and down within the pump chamber 107.

[0033] The high-sealing valve includes a sealing rod 108 and a gear I 203. The sealing rod 108 is welded to the right side of the sealing disc 109. The lower right part of the pump chamber 107 has an integrally formed notch, through which the sealing rod 108 passes. The right part of the valve body 304 has an integrally formed groove, and the gear I 203 is rotatably connected to the groove in the right part of the valve body 304. The middle of the gear I 203 has an integrally formed thread. The right side of the sealing rod 108 has an integrally formed notch, and the notch on the right side of the sealing rod 108 has an integrally formed thread. The sealing rod 108 and the gear... The threaded engagement of I203; because the sealing rod 108 passes through the notch in the lower right part of the pump chamber 107, it hinders the rotation and left and right movement of the sealing rod 108; because the gear I203 is rotatably connected in the groove in the right part of the valve body 304, it hinders the up and down movement of the gear I203; the rotation of gear I203 drives the thread in the middle of gear I203 to rotate, thereby driving the meshing sealing rod 108 to move up and down, thereby driving the sealing disc 109 to move up and down, thereby achieving the effect of the sealing disc 109 moving up and down in the pump chamber 107.

[0034] like Figure 7-11 As shown, this example can achieve the effect of gear I203 rotating.

[0035] Since the high-sealing valve includes a switch 201 and a gear II 202, the right part of the valve cover 101 is integrally formed with a hole. The switch 201 is rotatably connected to the hole in the right part of the valve cover 101 through a sealing ring. The gear II 202 is welded to the lower part of the switch 201 and meshes with the gear I 203. Rotating the switch 201 will drive the gear II 202 to rotate, which in turn will drive the gear I 203 meshing with the gear II 202 to rotate, thereby achieving the effect of rotating the gear I 203.

[0036] like Figure 9 As shown, this example can prevent excessive air pressure inside valve body 304.

[0037] The high-sealing valve includes a pressure relief chamber 204, a pressure relief valve 206, and a spring II 205. The pressure relief chamber 204 is welded to the upper side of the valve cover 101 and is located on the right side of the switch 201. The spring II 205 is welded inside the pressure relief chamber 204, and the pressure relief valve 206 is welded to the lower side of the spring II 205. The right side of the pressure relief chamber 204 has an integrally formed vent hole. When the pressure inside the valve body 304 is greater than the external atmospheric pressure, the air pressure inside the valve body 304 pushes the pressure relief valve 206 upward, thereby compressing the spring II 205, which in turn gives the pressure relief valve 206 a downward thrust. When the pressure inside the valve body 304 is too high, the air pressure inside the valve body 304 pushes the pressure relief valve 206 upward to above the exhaust port on the right side of the pressure relief chamber 204, thereby connecting the valve body 304 to the outside and reducing the air pressure inside the valve body 304, thus achieving the effect of reducing the air pressure inside the valve body 304 and preventing the air pressure inside the valve body 304 from becoming too high; the elastic force of the spring II 205 is greater than the pressure exerted on the pressure relief valve 206 by the air pressure inside the valve body 304, thereby pushing the pressure relief valve 206 downward to below the exhaust port, thus achieving the effect of closing the pressure relief valve 206.

[0038] like Figure 10 As shown, this example can achieve the effect of fixing the valve body 304.

[0039] Since the high-sealing valve includes a valve tube 301 and a threaded tube 303, the valve body 304 is welded to the upper side of the valve tube 301, thereby achieving the effect of fixing the valve body 304; the two threaded tubes 303 are respectively welded to the left and right sides of the valve tube 301, thereby achieving the effect of facilitating the installation of the valve body 304.

[0040] like Figure 12-13 As shown, this example can achieve the effect of opening and closing a valve.

[0041] The high-sealing valve includes a mesh cover 401 and a valve core 403. The mesh cover 401 is welded to the left side of the right-side threaded pipe 303, and multiple small holes are integrally formed on the mesh cover 401 at even intervals. The valve core 403 is slidably connected to the left side of the mesh cover 401, and the right side of the valve core 403 is in contact with the left side of the mesh cover 401. When the valve core 403 moves to the left, water on the right side of the valve flows through the multiple small holes on the mesh cover 401 to the left side of the valve, thus achieving the valve opening effect. When the valve core 403 moves to the right, the right side of the valve core 403 is in contact with the left side of the mesh cover 401, thus preventing water on the right side of the valve from flowing through the multiple small holes on the mesh cover 401 to the left side of the valve, thus achieving the valve closing effect.

[0042] like Figure 12-13 As shown, this example can achieve the effect of the valve core 403 slidingly connected to the left side of the mesh cover 401.

[0043] Since the high-sealing valve includes sliders 404 and grooves 402, the two sliders 404 are welded to the upper and lower sides of the right side of the valve core 403 respectively, and the two grooves 402 are integrally formed on the upper and lower sides of the mesh cover 401 respectively. The two sliders 404 are slidably connected in the two grooves 402 respectively, thereby restricting the rotation of the valve core 403, thereby achieving the effect of the valve core 403 being slidably connected to the left side of the mesh cover 401.

[0044] like Figure 12-13 As shown, this example can achieve the effect of controlling the opening and closing of a valve.

[0045] The high-sealing valve includes gear III 207, gear IV 208, and rack 405. A hole is integrally formed on the lower right side of the valve body 304. Gear III 207 is rotatably connected to the right side of the valve body 304 via a sealing ring. Gear III 207 meshes with gear II 202. Gear IV 208 is welded to the lower side of gear III 207. Rack 405 is welded to the left side of the valve core 403, and gear IV 208 meshes with rack 405. When switch 201 rotates clockwise, it drives gear II 202 to rotate clockwise. This causes gear III 207 to rotate counterclockwise, which in turn causes gear IV 208 to rotate counterclockwise, which in turn causes rack 405 to move to the left, thereby opening the valve and achieving the effect of controlling the valve to open; switch 201 rotates counterclockwise, which in turn causes gear II 202 to rotate counterclockwise, which in turn causes gear III 207 to rotate clockwise, which in turn causes gear IV 208 to rotate clockwise, which in turn causes rack 405 to move to the right, thereby closing the valve and achieving the effect of controlling the valve to close.
