Description

Technical Field

[0001] This utility model relates to the field of eccentric hemispherical valve technology, specifically an eccentric hemispherical valve. Background Technology

[0002] The eccentric hemispherical valve is a relatively new type of ball valve. It possesses unique structural advantages, such as frictionless switching, durable seals, and low opening and closing torque. This allows for a smaller actuator size, and when paired with a multi-turn electric actuator, it enables both media regulation and tight shut-off. It is widely applicable in applications requiring strict shut-off, such as petroleum, chemical, and urban water supply and drainage systems.

[0003] Currently, some eccentric ball valves still have some shortcomings in actual use. When installing some eccentric ball valves, they are often integrated with the base, which makes it difficult to remove the eccentric ball valve from the base for maintenance and replacement after long-term operation. This reduces the maintenance efficiency of the eccentric ball valve body, increases labor costs, and makes it impractical to use.

[0004] Therefore, this utility model provides an eccentric hemispherical valve to solve the above problems. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] This utility model provides an eccentric hemispherical valve, such as Figure 1-4 As shown, this eccentric hemispherical valve includes a support base 100, on which an eccentric hemispherical valve body 104 is mounted. A mounting seat 103 is located at one end of the eccentric hemispherical valve body 104. The mounting seat 103 has clamping grooves 301 at both ends for holding the mounting seat 103. A drive assembly 200 is mounted on the support base 100 to drive the clamping grooves 301 to move. Connecting plates 101 are fixedly connected to both ends of the support base 100. One side surface of the connecting plates 101 has several anti-slip textures 102. The drive assembly 200 allows the eccentric hemispherical valve body 104 to be easily removed for replacement or maintenance, reducing disassembly time, labor intensity, and work efficiency. The anti-slip textures 102 on the connecting plates 101 improve the stability of the equipment during operation, reduce vibration, and extend the equipment's service life.

[0018] A handwheel 105 is provided at one end of the eccentric ball valve body 104, and connecting seats 106 are provided on both sides of the eccentric ball valve body 104. Several screw holes 107 are provided on the connecting seats 106. A connecting post 108 is provided at the end of the eccentric ball valve body 104 away from the handwheel 105, and the connecting post 108 is fixedly connected to the mounting seat 103. The valve core can be raised and lowered by turning the handwheel 105. The connecting seats 106 can be easily connected to the output pipeline through the screw holes 107 provided on the connecting seats 106.

[0019] The drive assembly 200 includes a mounting frame 201 and a bidirectional motor 202. One end surface of the mounting frame 201 is fixedly connected to one end surface of the support base 100. The mounting frame 201 is fixedly connected to the bidirectional motor 202. Vertical plates 203 are fixedly connected to both sides of one end surface of the support base 100. A rotating rod 204 is fixedly connected to the output end of the bidirectional motor 202. A first bevel gear 205 is fixedly connected to one end surface of the rotating rod 204. When the switch of the bidirectional motor 202 is turned on, the output end of the bidirectional motor 202 drives the rotating rod 204 to rotate, and the rotation of the rotating rod 204 drives the first bevel gear 205 to rotate.

[0020] The support base 100 has two rotatably connected bidirectional screws 207 inside. One end of the bidirectional screw 207 passes through the support base 100 and is fixedly connected to a second bevel gear 206. The second bevel gear 206 meshes with the first bevel gear 205. The rotation of the first bevel gear 205 drives the second bevel gear 206 to rotate, and the rotation of the second bevel gear 206 drives the bidirectional screw 207 to rotate.

[0021] The support base 100 has grooves 109 at both ends on one side surface, and movable blocks 209 are slidably connected to the grooves 109. A guide rod 208 is fixedly connected inside the support base 100, and the guide rod 208 is slidably connected to the movable blocks 209. The movable blocks 209 are threadedly connected to the bidirectional screw 207. The rotation of the bidirectional screw 207 drives the two movable blocks 209 to move relative to each other on the guide rod 208.

[0022] A fixed plate 300 is fixedly connected to one end surface of the movable block 209, and one side surface of the fixed plate 300 is fixedly connected to one side surface of the clamping groove 301. The movement of the movable block 209 causes the fixed plate 300 to move, thereby causing the clamping groove 301 to move synchronously.

[0023] An electronic telescopic rod 302 is provided on one side surface of the clamping groove 301, and an anti-slip rubber pad 303 is fixedly connected to the output end of the electronic telescopic rod 302. The anti-slip rubber pad 303 is moved by the output end of the electronic telescopic rod 302, which increases the friction between the anti-slip rubber pad 303 and the mounting base 103, thereby further improving the stability of the equipment during operation.

[0024] In summary: When the eccentric hemispherical valve body 104 is required for operation, the operator moves the valve to the designated location, then uses bolts to install the delivery pipe and connecting seat 106 through the screw hole 107. Next, the operator adjusts the valve core by turning the handwheel 105. After prolonged use, the eccentric hemispherical valve body 104 needs to be inspected to check for wear and tear on the parts. The output end of the electronic telescopic rod 302 moves the anti-slip rubber pad 303, thereby loosening the fixation on the mounting seat 103. Then, the operator turns on the switch of the bidirectional motor 202, which drives the rotating rod 204 to rotate. The first bevel gear 205 is driven to rotate, which in turn drives the second bevel gear 206 to rotate. The second bevel gear 206 then drives the bidirectional screw 207 to rotate. The bidirectional screw 207 drives the two moving blocks 209 to move away from each other on the guide rod 208. The movement of the moving blocks 209 causes the fixed plate 300 to move synchronously, thereby causing the two clamping grooves 301 to move away from each other. This allows the eccentric hemispherical valve body 104 to be easily removed for inspection and maintenance, meeting the needs of the staff, reducing labor, improving the efficiency of inspection and maintenance of the eccentric hemispherical valve body 104, extending the service life of the eccentric hemispherical valve body 104, and greatly improving the practicality of the equipment.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
