Description

Technical Field

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

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, in particular, have a strong shearing force between the V-shaped ball core and the metal seat with hard alloy overlay, making them especially suitable for media containing fibers or small solid particles. Multi-port ball valves can flexibly control the merging, splitting, and switching of flow directions in pipelines, and can also close any channel while connecting the other two. These valves should generally be installed horizontally in pipelines. Ball valves are classified according to their actuation method: pneumatic ball valves, electric ball valves, and manual ball valves. Hard alloy ball valves evolved from traditional plug valves; their opening and closing element is a ball, which rotates around the valve stem axis to achieve the purpose of opening and closing.

[0003] Chinese patent publication (publication number: CN218818307U) discloses a high-temperature and high-pressure resistant valve ball, comprising: a ball, a valve stem, and a connecting rod. A square groove is connected to the ball, and the valve stem is inserted into the inner side of the square groove. A linkage cavity is provided inside the valve stem, and the connecting rod is slidably disposed inside the linkage cavity. This invention uses a sealing ring to seal the connection between the valve stem and the ball, preventing corrosion of the connecting rod inside the linkage cavity. Pulling the connecting rod upwards to abut against a positioning pin disengages the positioning pin from the linkage cavity, thus separating the valve stem from the ball. The sealing ring also prevents liquid leakage upwards from the linkage cavity.

[0004] The aforementioned equipment mainly relies on the tension of a spring to connect the valve stem and the ball head. However, in actual use, due to the resonant characteristics of the spring, the tension of the spring is not stable enough, which may cause the valve stem and the ball head to detach when connecting, which may affect the normal operation of the ball valve.

[0005] Therefore, a high-temperature resistant valve ball is proposed. Utility Model Content

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, this embodiment of the present invention provides a high-temperature resistant valve ball, comprising:

[0033] Ball assembly 1 includes a valve ball 101 and a first valve stem 103. A sleeve 102 is fixedly installed on the top of the valve ball 101. The first valve stem 103 is located on the top of the sleeve 102. A housing 104 is fixedly installed on the bottom of the first valve stem 103. A second valve stem 105 is fixedly installed on the bottom of the housing 104. Insertion holes 107 are provided around the inner cavity of the sleeve 102. A partition 106 is fixedly installed in the inner cavity of the second valve stem 105.

[0034] In this embodiment, the surface of the valve ball that comes into contact with the fluid is made of a high-temperature resistant material, such as high-temperature resistant stainless steel, to achieve the high-temperature resistance of the ball.

[0035] The disassembly and assembly component 2 includes a knob 201. A screw 202 is fixedly connected to the bottom of the knob 201. A screw block 203 is threadedly connected to the surface of the screw 202. An installation rod 204 is fixedly installed on both the front and rear sides of the bottom of the screw block 203. A trapezoidal plate 205 is fixedly installed on the other end of the installation rod 204. High-temperature resistant springs 206 are fixedly connected to the four sides of the inner cavity of the second valve stem 105. A moving block 207 is fixedly connected to the other end of each of the four high-temperature resistant springs 206. A trapezoidal block 208 is fixedly installed on the top of each of the four moving blocks 207. An insert block 209 is fixedly installed on the outer side of each of the four trapezoidal blocks 208.

[0036] By setting up the disassembly and assembly component 2, the rotation of the knob 201 causes the screw block 203 to drive the trapezoidal plate 205 to press against the trapezoidal block 208, causing the trapezoidal block 208 to drive the insert block 209 to move outward. The insert block 209 is inserted into the inner cavity of the insertion hole 107, realizing the connection between the second valve stem 105 and the valve ball 101. By quickly connecting the second valve stem 105 and the valve ball 101, it is convenient to disassemble, maintain or replace the valve ball 101 after long-term use and wear. This improves the speed and efficiency of assembling the valve ball 101 and the second valve stem 105, making it convenient for operators to use.

[0037] Example 2

[0038] like Figure 2-6 As shown, in one embodiment, slots 210 are provided on the surface of the second valve stem 105. Four inserts 209 penetrate the inner cavities of the four slots 210 and are inserted into the inner cavities of the insertion holes 107. The bottom of the second valve stem 105 is inserted into the inner cavity of the sleeve 102. The size of the second valve stem 105 matches the size of the inner cavity of the sleeve 102. The inner cavities of the four slots 210 and the inner cavities of the four insertion holes 107 are all in the same horizontal direction. The inner cavities of the four slots 210 are interconnected with the inner cavities of the four insertion holes 107. Guide rods are fixedly installed around the inner circumference of the second valve stem 105. 211, four movable blocks 207 are slidably connected to the surfaces of four guide rods 211, four trapezoidal blocks 208 are provided with grooves 212 at their top, the bottom of trapezoidal plate 205 is slidably connected to the inner cavity of the four grooves 212 around its perimeter, guide grooves 213 are provided on the front and rear sides of the top of partition 106, two mounting rods 204 pass through the inner cavity of the two guide grooves 213 and extend to the bottom of partition 106, limit rods 214 are fixedly installed on the left and right sides of the top of partition 106, and the left and right sides of screw block 203 are slidably connected to the inner cavity of the two limit rods 214.

[0039] By setting the slot 210, the movement of the insert block 209 can be limited, ensuring the accuracy of the direction of movement of the insert block 209. By setting the guide rod 211, the movement of the moving block 207 can be limited, ensuring the accuracy of the direction of movement of the moving block 207. By setting the slide groove 212, the movement of the trapezoidal plate 205 can be limited, ensuring that the trapezoidal plate 205 is stably attached to the top of the trapezoidal block 208. By setting the guide groove 213, the movement of the mounting rod 204 can be limited, preventing the mounting rod 204 from deviating during movement. By setting the limit rod 214, the movement of the screw block 203 can be limited, preventing the screw block 203 from rotating synchronously with the screw 202.

[0040] In operation, the present invention works as follows: First, the second valve stem 105 is inserted into the inner cavity of the sleeve 102. Then, the knob 201 is rotated, at which time the screw 202 rotates synchronously. The screw block 203 drives the mounting rod 204 and the trapezoidal plate 205 to move downward. Due to the shape characteristics of the trapezoidal plate 205 and the trapezoidal block 208, the trapezoidal plate 205 pushes the trapezoidal block 208 and the insert block 209 to move outward. At this time, the insert block 209 is inserted into the inner cavity of the insertion hole 107, and the high-temperature resistant spring 206 is affected by the movement of the trapezoidal block 208. The movable block 207 is pulled and deformed to connect the valve ball 101 and the second valve stem 105. When the valve ball 101 needs to be disassembled, the knob 201 is rotated in the opposite direction. At this time, the screw 202 drives the screw block 203, the mounting rod 204 and the trapezoidal plate 205 to move upward. The high-temperature spring 206 loses its force and pulls the movable block 207 to move inward. This causes the movable block 207 to drive the trapezoidal block 208 and the insert block 209 to move inward synchronously, thereby disassembling the second valve stem 105 and the valve ball 101.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
