Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a high-temperature resistant ball valve. Background Technology

[0002] A ball valve is a type of valve that controls the flow of fluid by rotating a ball. Its opening and closing element is a ball with a circular through hole. The ball is driven by the valve stem and rotates 90 degrees around the axis of the ball valve to open or close. It features low fluid resistance, good sealing performance, simple and quick operation, and wide applicability.

[0003] While existing ball valves perform well in fluid control, under high-temperature conditions, their sealing materials, ball, and valve seat are prone to deterioration in sealing performance, material aging, or even failure due to factors such as thermal expansion and thermal stress, thus affecting the service life of the ball valve. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant ball valve that effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A high-temperature resistant ball valve includes a ball valve body and a coolant tank. Two half-shells are bolted to the outer surface of the ball valve body, and a cooling cavity is formed between the two half-shells and the outer surface of the ball valve body. A water pump is installed inside the coolant tank, and a first hollow plate is mounted on the upper surface of the coolant tank, with the output end of the water pump connected to the bottom of the first hollow plate. An inlet pipe is connected to the outer surface of one half-shell, with its end connected to the first hollow plate. A return pipe is connected to the outer surface of the other half-shell, on the side away from the inlet pipe, with its end connected to the coolant tank. Two guide rods are connected to the outer surface of the half-shells. Two connecting plates are mounted on both sides of the upper surface of the coolant tank, and the connecting plates are bolted to the guide rods.

[0007] Therefore, by pumping coolant from the coolant tank into the cooling cavity between the two halves of the shell and the ball valve body, and then returning it to the coolant tank through the return pipe, the heat on the surface of the ball valve body can be carried away during the coolant circulation process, thereby achieving the purpose of cooling it and preventing the ball valve body from being in a high-temperature environment for a long time, which would affect its service life and improve its high-temperature resistance.

[0008] Furthermore, the interior of the first hollow plate is equipped with multiple parallel partitions, which divide the interior of the first hollow plate into multiple flow channels. The surface of the partitions is provided with through holes, and the through holes on two adjacent partitions are located on opposite sides.

[0009] Furthermore, heat dissipation fins are provided on both outer surfaces of the first hollow plate, and the heat dissipation fins are arranged in a horizontal direction.

[0010] Furthermore, a fan is installed on the outer surface of the coolant tank, and a second hollow plate is installed at the output end of the fan. Two sets of parallel air outlets are opened on the side of the second hollow plate facing the heat dissipation fins.

[0011] Furthermore, a drain pipe is connected to the outer surface of the coolant tank, and a valve is installed inside the drain pipe. An injection port is provided on the upper surface of the coolant tank, and a sealing plug is connected to the internal thread of the injection port.

[0012] Furthermore, a first threaded connector is installed on the upper surface of the coolant tank, which is threadedly connected to the return pipe, and a second threaded connector is installed on the upper surface of the first hollow plate, which is threadedly connected to the inlet pipe.

[0013] Furthermore, sealing gaskets are provided at the edges of the opposing surfaces of the two half-shells.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model uses a water pump to draw coolant from the coolant tank into the cooling cavity between the two halves of the shell and the ball valve body, and then returns it to the coolant tank through the return pipe. Therefore, during the circulation of coolant, the heat on the surface of the ball valve body can be carried away, achieving the purpose of cooling it and avoiding the ball valve body being in a high-temperature environment for a long time, which would affect its service life and improve its high-temperature resistance.

[0016] 2. This utility model separates the return pipe from the first threaded connector, the inlet pipe from the second threaded connector, and the connecting plate from the guide rod. Subsequently, the half-shell can be removed from the ball valve body, enabling free disassembly and assembly of the half-shell and the coolant tank, which facilitates maintenance and replacement.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4This utility model provides a high-temperature resistant ball valve, comprising a ball valve body 100 and a coolant tank 102. Two half-shells 101 are bolted to the outer surface of the ball valve body 100, and a cooling cavity is provided between the two half-shells 101 and the outer surface of the ball valve body 100. A water pump is installed inside the coolant tank 102, and a first hollow plate 103 is installed on the upper surface of the coolant tank 102, with the output end of the water pump connected to the bottom of the first hollow plate 103. An inlet pipe 104 is connected to the outer surface of one half-shell 101, with its end connected to the first hollow plate 103. A return pipe 105 is connected to the outer surface of the other half-shell 101, away from the inlet pipe 104, with its end connected to the coolant tank 102. Two guide rods 107 are connected to the outer surface of the half-shell 101. Two connecting plates 106 are installed on both sides of the upper surface of the coolant tank 102, and the connecting plates 106 are connected to the guide rods 107 by bolts.

[0026] During use, the water pump is started, drawing coolant from the coolant tank 102 into the first hollow plate 103. The coolant then enters the cooling cavity between the two half-shells 101 and the ball valve body 100 through the inlet pipe 104. The coolant flows within the cooling cavity, absorbing heat from the surface of the ball valve body 100, and then flows back to the coolant tank 102 through the return pipe 105. This effectively cools the ball valve body 100, preventing it from being exposed to high temperatures for extended periods and thus extending its service life, thereby improving its high-temperature resistance. Furthermore, the half-shells 101 are bolted to the outside of the ball valve body 100, without damaging or altering its internal structure, ensuring normal operation of the ball valve body 100. They can also be disassembled and reassembled like accessories, offering high flexibility.

[0027] Preferably, a plurality of parallel partitions 200 are installed inside the first hollow plate 103. The partitions 200 divide the interior of the first hollow plate 103 into a plurality of flow channels 201. Through holes 202 are provided on the surface of the partitions 200, and the through holes 202 on two adjacent partitions 200 are located on opposite sides.

[0028] When the water pump draws the coolant into the first hollow plate 103, it flows through multiple flow channels 201 in sequence, thus providing the coolant with flow time so that it can be cooled before entering the cooling cavity.

[0029] Preferably, heat dissipation fins 300 are provided on both outer surfaces of the first hollow plate 103, and the heat dissipation fins 300 are arranged in a horizontal direction.

[0030] The coolant conducts heat to the surface of the first hollow plate 103, and the heat dissipation fins 300, after absorbing heat, can increase the contact area with the air, thus improving the cooling effect of the coolant. Furthermore, both the first hollow plate 103 and the heat dissipation fins 300 are made of copper, which has better thermal conductivity and better heat dissipation effect.

[0031] Preferably, a fan 400 is installed on the outer surface of the coolant tank 102, and a second hollow plate 401 is installed at the output end of the fan 400. The second hollow plate 401 has two sets of parallel air outlet holes 402 on the side facing the heat dissipation fins 300.

[0032] When the fan 400 starts, it generates airflow. The airflow enters the second hollow plate 401 and is blown out horizontally from the air outlet 402. Since the heat dissipation fins 300 are arranged in a horizontal direction, the blown air can contact the surface of the heat dissipation fins 300 and carry away its heat, thereby further improving the cooling effect on the coolant and reducing it to a suitable temperature before entering the cooling cavity, ensuring the heat dissipation effect on the ball valve body 100.

[0033] Preferably, a drain pipe 500 is connected to the outer surface of the coolant tank 102, a valve is provided inside the drain pipe 500, and an injection port is provided on the upper surface of the coolant tank 102, with a sealing plug 501 threaded inside the injection port.

[0034] The coolant in the coolant tank 102 can be replaced periodically by the drain pipe 500 and the sealing plug 501, ensuring the cooling effect of the coolant.

[0035] Preferably, a first threaded connector 600 is installed on the upper surface of the coolant tank 102, and the first threaded connector 600 is threadedly connected to the return pipe 105. A second threaded connector 601 is installed on the upper surface of the first hollow plate 103, and the second threaded connector 601 is threadedly connected to the inlet pipe 104.

[0036] By separating the return pipe 105 from the first threaded connector 600, separating the inlet pipe 104 from the second threaded connector 601, and separating the connecting plate 106 from the guide rod 107, the half housing 101 can be removed from the ball valve body 100, enabling free disassembly and assembly of the half housing 101 and the coolant tank 102, facilitating maintenance and replacement.

[0037] Preferably, sealing gaskets are provided at the edges of the opposite sides of the two half-shells 101.

[0038] The sealing gasket ensures a tight seal at the joint between the two halves of the housing 101, preventing coolant leakage.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
