Description

Technical Field

[0001] This invention relates to the field of ball valve technology, specifically a ferrule ball valve. Background Technology

[0002] Compression fitting ball valves are widely used in fluid transport systems due to their simple structure and reliable sealing performance. The existing connection structure of a compression fitting ball valve mainly includes a valve body, a compression ring located at the valve body interface, and a nut that threads with the valve body interface. The connection principle is as follows: after inserting the pipe into the valve body interface, tightening the nut compresses the compression ring (a tapered metal sleeve), causing the cutting edge of the compression ring to embed into the outer wall of the pipe, thereby forming a mechanical compression seal and achieving a fixed connection and seal between the pipe and the ball valve.

[0003] However, in actual installation scenarios, it is common to encounter situations where the pipe position is fixed in advance. For example, in the fluid piping systems of some precision equipment, the pipe is pre-installed in a specific position using supports or other fixed structures. In this case, the end position of the pipe is strictly limited and cannot be moved or adjusted axially. Existing compression fitting ball valve installation methods require the free end of the pipe to be inserted into the valve body interface before the nut can be tightened. When the pipe position is pre-fixed, the pipe cannot be inserted into the valve body interface, making it impossible to install the compression fitting ball valve normally. This greatly limits the applicability of compression fitting ball valves and causes many inconveniences in installation and construction. Summary of the Invention

[0004] The purpose of this invention is to provide a ferrule ball valve to solve the problems mentioned in the background art.

A lateral restraint assembly is provided between the first installation ring and the second installation ring.

[0009] Furthermore, the compression fitting assembly includes an external threaded sleeve, which is fixedly sleeved on the end of the connecting pipe two.

A sealing clamping head is fixedly connected to the end of the nut.

[0010] Furthermore, a ceramic sealing sleeve is embedded in the gap between the rotating sleeve and the inlet and outlet pipes, and the cross-section of the ceramic sealing sleeve is L-shaped.

[0011] Furthermore, a corrugated sleeve is provided on the end face of the fixed tube and the telescopic tube away from the rotation adjustment component, and the corrugated sleeve covers the end face of the fixed tube away from the rotation adjustment component.

[0012] Furthermore, a guide groove is provided in the recessed groove, a connecting body is fixedly provided on the connecting ring, the connecting body is slidably provided in the guide groove, a metal elastic strip one is fixedly installed on the left outer wall of the connecting body, a metal elastic strip two is fixedly installed on the right outer wall of the connecting body, and the ends of the metal elastic strip two and the metal elastic strip one away from the connecting body are fixedly connected to the inner wall of the guide groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The rotating adjustment component allows the telescopic adjustment component to rotate relative to the inlet and outlet pipes. During installation, rotating the telescopic adjustment component will cause the bend adjustment component to rotate, which in turn will cause the compression fitting component connected to the bend adjustment component to rotate. This allows the fitting to avoid complex piping or to align the compression fitting component with the pipe port to be connected. The telescopic adjustment component is used to extend and retract, and then the position of the bend adjustment component is adjusted, which in turn adjusts the position of the compression fitting component, so that the fitting is inserted into the pipe port.

[0016] The bend adjustment component is set up to bend and adjust the position of the compression fitting assembly, so that the ball valve body can move up and down, thereby allowing the entire ball valve to be staggered in the pipeline, further reducing the space occupied in the pipeline.

[0017] A connecting ring is provided to connect silicone sleeve one and silicone sleeve two to the ball valve body via the telescopic tube, thereby ensuring a complete seal between the end of the telescopic tube that extends into the fixed tube and the inside of the fixed tube. The elastic silicone sleeve one and silicone sleeve two are used as elastic expansion components to ensure the elastic connection and telescopic connection between the fixed tube and the telescopic tube.

[0018] The bent pipe serves as the connecting pipe one and connecting pipe two, allowing the compression fitting assembly to bend relative to the telescopic adjustment assembly. Mounting ring one and mounting ring two are provided for mounting the lateral restraint assembly, which restricts the bending direction of the metal bent pipe, thereby preventing significant shaking of the entire ball valve after connecting to the pipeline port.

Both the inlet pipe 2 and the outlet pipe 3 are connected to a rotary adjustment assembly 4. The rotating end of the rotary adjustment assembly 4 is connected to a telescopic adjustment assembly 5, and the telescopic end of the telescopic adjustment assembly 5 is connected to a bend adjustment assembly 6. The bend end of the bend adjustment assembly 6 is provided with a compression fitting connector assembly 7. The rotary adjustment assembly 4 is configured so that the telescopic adjustment assembly 5 can rotate relative to the inlet pipe 2 and the outlet pipe 3. Thus, during installation, the telescopic adjustment assembly 5 can be rotated to drive the bend. The rotation of the adjusting component 6 causes the ferrule fitting component 7 connected to the bend adjusting component 6 to rotate, which can avoid complex pipelines or align the ferrule fitting component 7 with the pipeline port to be connected. The telescopic adjusting component 5 is set to extend and retract to adjust the position of the bend adjusting component 6, and then adjust the position of the ferrule fitting component 7, so that the connecting pipeline port is inserted into the ferrule fitting component 7. The bend adjusting component 6 is set to bend and adjust the position of the ferrule fitting component 7, so that the ball valve body 1 can move up and down, and thus the entire ball valve can be staggered in the pipeline, further reducing the space occupied in the pipeline.

[0023] The rotary adjustment assembly 4 includes an arc-shaped groove 401 and a rotating sleeve 402. The arc-shaped groove 401 is formed on the outer side wall of the ball valve body 1 of the inlet pipe 2 and the outlet pipe 3.

Silicone sealing rings 404 are fixedly provided on the left and right outer walls of the ceramic sealing ring 403. The silicone sealing rings 404 are respectively inserted into the arc-shaped groove 401 and the arc-shaped groove 405. An outer limiting ring 406 is fixedly sleeved on the outer side of the sealing ring 403. The outer limiting ring 406 is located between the inner wall of the rotating sleeve 402 and the end faces of the water inlet pipe 2 and the water outlet pipe 3. The rotating sleeve 402 serves as a rotating component to connect the telescopic adjustment assembly 5 with the water inlet pipe 2 and the water outlet pipe 3. A ceramic sealing ring 403 and a silicone sealing ring 404 are provided as movable sealing components to ensure the sealing performance at the connection between the rotating sleeve 402 and the water inlet pipe 2 and the water outlet pipe 3.

A silicone sleeve 1 505 is fixedly connected to the left outer wall of the connecting ring 503, and a silicone sleeve 2 505 is fixedly connected to the right outer wall of the ball valve body 1. 6. The ends of silicone sleeve 1 505 and silicone sleeve 2 506 away from the connecting ring 503 are fixedly connected to the inner wall of the recessed groove 504. The connecting ring 503 is set to connect silicone sleeve 1 505 and silicone sleeve 2 506 to the ball valve body 1 together with the telescopic tube 502, so that the end of the telescopic tube 502 that extends into the fixed tube 501 forms a complete seal with the inside of the fixed tube 501. The elastic silicone sleeve 1 505 and silicone sleeve 2 506 are used as elastic telescopic components to ensure the elastic connection and telescopic connection between the fixed tube 501 and the telescopic tube 502.

[0025] The bend adjustment assembly 6 includes a first connecting pipe 601 and a second connecting pipe 602. The first connecting pipe 601 is fixedly connected to the telescopic pipe 502, and the interior of the first connecting pipe 601 is connected to the interior of the telescopic pipe 502. An installation ring 604 is fixedly sleeved on the outer wall of the end of the first connecting pipe 601 connected to the telescopic pipe 502. The first connecting pipe 601 and the second connecting pipe 602 are connected by a metal bend pipe 603. An installation ring 605 is fixedly sleeved on the end of the second connecting pipe 602 connected to the metal bend pipe 603. A lateral limiting component is provided between mounting ring 604 and mounting ring 605. The metal bent pipe 603 serves as a bend connecting pipe 601 and pipe 602, allowing the compression fitting assembly 7 to bend relative to the telescopic adjustment assembly 5. Mounting rings 604 and 605 are used to install the lateral limiting component, which restricts the bending direction of the metal bent pipe 603, thereby preventing significant shaking of the ball valve after connecting to the pipeline port.

[0026] The compression fitting assembly 7 includes an external threaded sleeve 701, which is fixedly sleeved on the end of the connecting pipe 602. A connecting sleeve 704 is clamped to the inner side of the external threaded sleeve 701. A nut 702 is threaded on the outer wall of the external threaded sleeve 701. A sealing clamping head 703 is fixedly connected to the end of the nut 702. By rotating the nut 702, the connecting sleeve 704 is squeezed, so that the connecting sleeve 704 clamps the pipe port inserted into the connecting sleeve 704. The sealing clamping head 703 is provided to seal the connection.

[0027] A ceramic sealing sleeve 8 is embedded in the gap between the rotating sleeve 402 and the inlet pipe 2 and the outlet pipe 3. The cross-section of the ceramic sealing sleeve 8 is L-shaped. The ceramic sealing sleeve 8 is set to form axial limit and radial support, which can effectively prevent the rotating sleeve 402 from radially offset and axially shaking.

[0028] A corrugated sleeve 9 is provided on the end face of the fixed tube 501 and the telescopic tube 502 away from the rotation adjustment component 4. The corrugated sleeve 9 covers the end face of the fixed tube 501 away from the rotation adjustment component 4. The corrugated sleeve 9 can form a seal at the port of the fixed tube 501 and the telescopic tube 502, which can prevent dust and other objects from entering the inner groove 504.

[0029] A guide groove 10 is provided in the recessed groove 504. A connector 11 is fixedly installed on the connecting ring 503. The connector 11 is slidably installed in the guide groove 10. A metal elastic strip 12 is fixedly installed on the left outer wall of the connector 11, and a metal elastic strip 13 is fixedly installed on the right outer wall of the connector 11. The ends of the metal elastic strip 12 and the metal elastic strip 13 away from the connector 11 are fixedly connected to the inner wall of the guide groove 10. The guide groove 10 and the connector 11 are used to limit the telescopic tube 502, which can prevent the telescopic tube 502 from rotating relative to the fixed tube 501, and at the same time provide elastic traction force for the fixed tube 501 and the telescopic tube 502.

[0030] The lateral restraint assembly includes a first fixing ring 14 and a second fixing ring 15. The first fixing ring 14 is fixedly connected to the second mounting ring 605, and the second fixing ring 15 is fixedly connected to the first mounting ring 604. An elastic bending strip 16 is connected between the first fixing ring 14 and the second fixing ring 15, and three elastic bending strips 16 are provided. The three elastic bending strips 16 are located above and in the front and rear directions of the metal bending tube 603, respectively. An elastic bending wire 17 is fixedly provided at the center of the elastic bending strip 16. The bending direction of the first fixing ring 14 and the second fixing ring 15 is restricted by the three elastic bending strips 16 with fixed bending directions, thereby restricting the bending direction of the first connecting tube 601 and the second connecting tube 602, and preventing the first connecting tube 601 and the second connecting tube 602 from bending arbitrarily.

[0031] Working principle: In use, according to the distribution of pipelines and the position of pipeline ports, rotate the telescopic adjustment component 5 to drive the bending adjustment component 6 to rotate, thereby changing the orientation of the compression fitting component 7. Then bend the metal bending pipe 603 to change the angle of the compression fitting component 7. Then align the compression fitting component 7 with the pipeline port. Then press the telescopic pipe 502 to retract it into the fixed pipe 501, aligning the pipeline port with the connecting ferrule 704. After releasing the telescopic pipe 502, the metal elastic strip 12 and the metal elastic strip 23 push the telescopic pipe 502 to move, thereby driving the compression fitting component 7 to move, so that the pipeline port is inserted into the connecting ferrule 704. Use a tool to rotate the nut 702, so that the nut 702 moves and then squeezes the connecting ferrule 704, thus performing a compression fitting connection on the pipeline port.

[0032] Example 2: Please refer to Figures 1-10 This invention provides a technical solution: a compression fitting ball valve, comprising a ball valve body 1, an inlet pipe 2 connected to the right end of the ball valve body 1, and an outlet pipe 3 connected to the left end of the ball valve body 1. Both the inlet pipe 2 and the outlet pipe 3 are connected to a rotary adjustment assembly 4. The rotating end of the rotary adjustment assembly 4 is connected to a telescopic adjustment assembly 5, and the telescopic end of the telescopic adjustment assembly 5 is connected to a bend adjustment assembly 6. The bend end of the bend adjustment assembly 6 is provided with a compression fitting connector assembly 7. The rotary adjustment assembly 4 is configured so that the telescopic adjustment assembly 5 can rotate relative to the inlet pipe 2 and the outlet pipe 3. Thus, during installation, the telescopic adjustment assembly 5 can be rotated to drive the bend. The rotation of the adjusting component 6 causes the ferrule fitting component 7 connected to the bend adjusting component 6 to rotate, which can avoid complex pipelines or align the ferrule fitting component 7 with the pipeline port to be connected. The telescopic adjusting component 5 is set to extend and retract to adjust the position of the bend adjusting component 6, and then adjust the position of the ferrule fitting component 7, so that the connecting pipeline port is inserted into the ferrule fitting component 7. The bend adjusting component 6 is set to bend and adjust the position of the ferrule fitting component 7, so that the ball valve body 1 can move up and down, and thus the entire ball valve can be staggered in the pipeline, further reducing the space occupied in the pipeline.

A valve stem 103 is fixedly connected to the center of the spherical raft plate 101. The top end of the valve stem 103 extends out of the valve cavity, and a plug connector 104 is fixedly connected to the top end of the valve stem 103. A snap-fit ​​head 105 is fixedly installed on the outer wall of the plug connector 104. A handle 106 is snapped onto the plug connector 104 and the snap-fit ​​head 105. A sealing packing 107 and a silicone sealing ring 108 are installed at the part of the valve stem 103 that penetrates the ball valve body 1. The silicone sealing ring 108 is located above the sealing packing 107. The plug connector 104 and the snap-fit ​​head 105 are used to snap-fit ​​the handle 106 so that the handle 106 can be directly removed from the ball valve body 1. The sealing packing 107 and the silicone sealing ring 108 are used to form a seal at the part of the valve stem 103 that extends out of the ball valve body 1 to prevent fluid leakage from that point.

[0034] Working principle: When in use, align the handle 106 with the connector 104 and the latch head 105 and press it down, then lock the handle 106 onto the connector 104 and the latch head 105. Then rotate the handle 106 to drive the connector 104 to rotate, which in turn drives the valve stem 103 to rotate. The rotation of the valve stem 103 drives the spherical raft plate 101 to rotate. The rotation angle of the spherical raft plate 101 controls the opening and closing of the entire ball valve and the change of the opening and closing size.
