Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant ball valves, and in particular to a high-pressure floating hard-sealed wear-resistant ball valve and a use method thereof. Background Art

[0002] In the traditional high-pressure ball valve design, the friction between the ball and the pipe wall is one of the main reasons for the decline in sealing effect. Although the existing technology has improved the overall durability of the ball valve by enhancing the wear resistance of the sealing component, such as introducing hard sealing technology and using wear-resistant materials, these methods mainly focus on the wear resistance of the sealing component and cannot fundamentally solve the friction problem between the ball and the pipe wall.

[0003] Publication No. "CN204610938U" discloses a high-pressure floating hard-sealed wear-resistant ball valve, whose metal valve seat makes the valve seat and the ball seal a hard seal, which is not easy to wear during operation and has a long service life. Even if the sealing surface of the valve seat and the ball is worn, the arrangement of the pressure ring, seal and spring enables the spring to still press the metal valve seat, so that the valve seat and the ball are reliably sealed. The utility model also has the advantages of simple structure, easy assembly, long service life and reliable sealing.

[0004] In actual use, during the operation of the ball valve, especially under high-pressure conditions, the ball must rotate to open or close the fluid channel. The direct contact between the ball and the inner wall of the pipe will produce friction. As the use time increases, this friction will cause wear of the ball and the inner wall of the pipe, which will in turn affect the sealing effect and the operating performance of the valve. In addition, friction will also cause heat generation, increase material fatigue, and thus accelerate the aging and damage of the sealing surface. Although the service life of the ball valve can be extended and its reliability can be improved to a certain extent by improving the material and structural design to increase the wear resistance and corrosion resistance of the valve components, these measures have failed to fundamentally eliminate the friction problem between the ball and the pipe wall. Summary of the invention

[0036] The adjusting component 96 is installed on the inner wall of the assembly plate 6, and is used to drive the connecting plate 95 to move on the inner wall of the clamping sleeve plate 8.

[0037] It should be noted that the outer wall of the sphere 94 described in this embodiment is provided with a flow groove, and the flow groove has the same size as the slot 951 .

[0038] Specifically, in the process of using the ball valve, in order to avoid friction between the ball 94 and the inner wall of the pipe, one end of the sealing pipe 91 is fixedly penetrated through the top of the outer wall of the clamping sleeve 8, the support platform 92 is fixedly connected to the other end of the sealing pipe 91, and one end of the adjustment rod 93 successively penetrates the support platform 92 and the sealing pipe 91, and is fixedly connected to the outer wall of the ball 94. Two connecting plates 95 are provided, and are symmetrically slidably clamped on the inner wall of the clamping sleeve 8 and located on both sides of the ball 94. The adjustment component 96 is installed on the inner wall of the assembly plate 6. The connecting plate 95 is provided with a sealing assembly 97 mounted on the supporting platform 92, and is used to drive the connecting plate 95 to move on the inner wall of the clamping sleeve plate 8. The sealing assembly 97 is mounted on the supporting platform 92, and is used to protect the sphere 94 and seal the slot 951 opened on the connecting plate 95. One end of the auxiliary assembly 98 is mounted on the inner wall of the assembly plate 6, and the other end of the auxiliary assembly 98 is mounted on one side of the connecting plate 95. The monitoring assembly 99 is mounted on the inner wall of the sphere 94, and is used to monitor the flow rate of the water flow. Then, when the operation is turned on, the gas is extracted, the air pump 971 is started, and the air cushion 972 is moved. The gas in the connecting plate 95 is extracted, the connecting plate 95 is adjusted, and the adjusting assembly 96 is used to ensure that the connecting plate 95 is in the correct position so that the flow slot is aligned with the slot 951 on the connecting plate 95, and the adjusting rod 93 is rotated to drive the ball 94 to rotate to the open position, so that the flow slot of the ball 94 is aligned with the slot 951 on the connecting plate 95 to achieve water flow. When closing the connecting plate 95, the adjusting assembly 96 is used again to adjust the position of the connecting plate 95 so that it is disconnected from the ball 94, and the ball 94 is rotated to move the ball 94 to the open position. 4 Rotate 90 degrees to make the flow groove and the slot 951 on the connecting plate 95 form an angle of 90 degrees. At this time, the ball valve is in a closed state, and air is injected to seal. Start the air pump 971 to inject air into the air cushion 972. After the air cushion 972 expands, it can effectively seal the slot 951 on the connecting plate 95, thereby achieving the sealing closure of the valve, thereby avoiding direct contact between the ball 94 and the inner wall of the pipeline, thereby avoiding friction, and then fundamentally eliminating the friction problem between the ball and the pipeline wall, improving the wear resistance of the ball 94, and better stability.

[0039] In order to clearly illustrate the above embodiment, in one example of the present application, Figure 1-Figure 10 As shown, the adjustment assembly 96 includes a mounting plate 961, a cylinder 962, a driving rod 963 and a fixing plate 964, wherein the mounting plate 961 is fixedly connected to the center of the inner wall of the assembly plate 6, the cylinder 962 is installed at the center of one side of the mounting plate 961, one end of the driving rod 963 is fixedly connected to the output end of the cylinder 962, one side of the fixing plate 964 is slidably sleeved on the other end of the driving rod 963, and the other side of the fixing plate 964 is fixedly connected to one side of the connecting plate 95.

[0040] Specifically, in order to avoid friction between the ball 94 and the connecting plate 95, the mounting plate 961 is fixedly connected to the center of the inner wall of the assembly plate 6, the cylinder 962 is installed at the center of one side of the mounting plate 961, one end of the driving rod 963 is fixedly connected to the output end of the cylinder 962, one side of the fixing plate 964 is slidably sleeved on the other end of the driving rod 963, and the other side of the fixing plate 964 is fixedly connected to one side of the connecting plate 95. When the ball 94 needs to be rotated, the cylinder 962 can be started, and under the action of the driving rod 963 and the fixing plate 964, the connecting plate 95 can be driven to move its position. Therefore, when the ball 94 rotates, friction between the ball 94 and the groove 951 on the connecting plate 95 can be avoided, thereby effectively improving the wear resistance of the ball 94.

[0042] It should be noted that an air injection hole is provided at the end of the connecting pipe 973 described in this embodiment, and air can be injected into the interior of the air cushion 972 through the air injection hole.

The outer wall of the air cushion 972 is provided with an assembly hole 9721 for fixing one end of the connecting pipe 973. The air pump 971 is started to extract the gas in the air cushion 972, and the adjusting rod 93 is rotated to drive the sphere 94 to rotate to the open position. The position is set so that the flow groove of the sphere 94 is aligned with the groove 951 on the connecting plate 95 to achieve water flow, and the air pump 971 is started to inject air into the air cushion 972. After the air cushion 972 expands, it can effectively seal the groove 951 on the connecting plate 95, thereby achieving the sealed closure of the valve, thereby avoiding direct contact between the sphere 94 and the inner wall of the pipeline, thereby avoiding friction, and fundamentally eliminating the friction problem between the sphere 94 and the pipeline wall, thereby improving the wear resistance of the sphere 94 and improving stability.
