Description

Technical Field

[0001] This invention relates to the field of mechanical valve technology, specifically to a mechanical valve that is opened and closed by rotation control. Background Technology

[0002] Valves are used to control the flow of fluid in pipelines and are common control components in modern industry. Currently, most valves on the market can only control one fluid channel. When it is necessary to open and close multiple fluid channels simultaneously, multiple valves must be installed, and synchronous control can be achieved through electrical signals.

[0003] However, multiple valves controlled synchronously by electrical signals require circuit connections, and multiple valves are expensive, difficult to install, and have high maintenance costs. Therefore, a mechanical valve that can directly control multiple fluid channels synchronously is needed to simplify the structure and reduce production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary-controlled mechanical valve that can synchronously control the fluid in multiple pipelines, thereby reducing pipeline installation and maintenance costs.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: a rotary control mechanical valve, comprising a pipe for fluid passage, two end sleeves respectively fixed at both ends of the pipe, a sliding valve sleeve, and a rotary valve sleeve. The pipe is fixed between the two end sleeves, the sliding valve sleeve is fitted onto the pipe and is slidable relative to the pipe, and the rotary valve sleeve is fitted onto the sliding valve sleeve. The two ends of the rotary valve sleeve are rotatably connected to the two end sleeves respectively. A guide mechanism is provided on the contact surface between the rotary valve sleeve and the sliding valve sleeve. When the rotary valve sleeve rotates, the guide mechanism drives the sliding valve sleeve to slide on the pipe, thereby controlling the opening and closing of the fluid passage within the control valve.

[0006] Compared with the prior art, the rotary-controlled mechanical valve that adopts the above technical solution has the following advantages:

[0007] Beneficial effects:

[0008] 1. The mechanical valve with rotary control opening and closing of the present invention can control the flow of the internal pipeline by rotating the valve sleeve on the outside of the valve, making the control more convenient and faster.

[0009] Second, a control valve can be equipped with multiple pipes for fluid to pass through. By rotating a rotary valve sleeve, the opening and closing of all pipes in the sliding valve sleeve can be controlled simultaneously, and the fluids in different pipes will not come into contact with each other, reducing the cost of using valves with multiple pipes.

[0010] Preferably, the pipe is provided with a blockage block, which is located in the middle of the pipe and divides the interior of the pipe into two non-communicating spaces. The pipe is also provided with a plurality of vent holes, which are respectively located on both sides of the blockage block. The sliding valve sleeve is provided with a through hole for the pipe to pass through. The inner wall of the through hole is provided with a vent groove, which is an annular groove arranged around the inner wall of the through hole. When the sliding valve sleeve slides, it causes the vent groove to cover or move away from the vent hole.

[0011] The flow of fluid between the two ends of a pipeline is achieved by connecting and disconnecting vent holes and vent grooves. The sliding mechanism makes it more convenient and the structure is simpler, reducing the manufacturing cost of mechanical valves.

[0012] Preferably, the guiding mechanism includes a groove and a slider. The groove is disposed on the outer side of the sliding valve sleeve and is elongated. The line connecting the two ends of the groove is not parallel to the length direction of the pipe. The slider is fixed on the inner side of the rotary valve sleeve and is located in the groove. When the rotary valve sleeve rotates, the slider on the rotary valve sleeve drives the sliding valve sleeve to slide.

[0013] Preferably, it further includes a limiting mechanism for restricting the rotation of the rotary valve sleeve, the limiting mechanism being disposed between the rotary valve sleeve and the end sleeve.

[0014] Preferably, the limiting mechanism includes a fixing bolt, a limiting piece, and a limiting groove formed on the rotary valve sleeve. The fixing bolt is fixed to the end sleeve, the limiting end of the limiting piece is located in the limiting groove, the limiting piece is sleeved on the fixing bolt and can slide along the length direction of the fixing bolt, and when the limiting piece slides on the fixing bolt, the limiting end moves in and out of the limiting groove.

[0015] By locking and unlocking the rotary valve sleeve through the limiting mechanism, it is possible to ensure that the inside of the mechanical valve is in a stable connected or disconnected state, and to ensure that the rotary valve sleeve and the sliding valve sleeve will not be displaced due to vibration or other reasons.

[0016] Preferably, the end sleeve has a slot, the fixing bolt is disposed at the bottom of the slot, the limiting groove covers the slot, and the fixing bolt is also provided with an elastic element. The elastic element is located between the bottom of the slot and the limiting element. The limiting end of the limiting element is located in the limiting groove under the action of the elastic element. When the limiting element is pressed, the elastic element is compressed, and the limiting end moves into the slot.

[0017] Pressing the limiting component causes it to be pressed down into the slot. When released, the limiting component returns to the limiting slot under the action of the elastic component, achieving automatic reset without the need for secondary manual adjustment.

[0018] Preferably, there are two limiting grooves, which are disposed at one end of the rotary valve sleeve. When the slider slides from one end of the slide groove to the other end of the slide groove, the limiting end moves from one limiting groove to the other limiting groove.

[0019] Preferably, it also includes a connector, which includes a connector seat and a connector nozzle. The connector seat is detachably fixed to the end sleeve. The end sleeve is provided with a protrusion. The side of the connector seat that is fixed to the end sleeve is provided with an annular groove that facilitates the insertion of the protrusion. A stop is provided on the groove wall of the annular groove. The end of the protrusion is located in the sliding groove and is locked in the sliding groove by the stop.

[0020] It can be used to quickly connect to other pipes without the need for additional parts.

[0021] Preferably, the side of the connecting seat is provided with a locking groove, the locking groove is connected to the annular groove, one end of the limiting piece is a limiting end and the other end is a locking end, the locking end is located in the locking groove and moves in and out of the annular groove under the action of external force.

[0022] By using limiting components and locking grooves, after the connector and end sleeve are fixed together, the connector can be prevented from sliding relative to the end sleeve, thus ensuring the stability of the connection.

[0023] Preferably, the connecting seat includes a base plate and a connecting ring. The base plate has a through hole, the connecting nozzle is inserted into the through hole, the outside of the connecting nozzle is provided with a clamp to prevent the connecting nozzle from falling off, the end sleeve has an opening, the connecting nozzle is inserted into one end of the opening, the annular groove is provided on the connecting ring, and the base plate is provided between the base plate and the connecting ring.

[0024] One end of the connector is inserted into the opening of the end sleeve, ensuring the airtightness of the connection of the fluid passage inside the mechanical valve. Furthermore, the fluid valve has multiple fluid passages, ensuring that the pipes, openings, and connectors corresponding to each fluid passage are mutually compatible, preventing misalignment and fluid leakage.

[0041] The present invention will now be further described with reference to the accompanying drawings.

[0042] like Figure 1The rotary-controlled mechanical valve shown includes several pipes 1 for fluid passage, two end sleeves 2 respectively fixed at both ends of the pipes 1, a sliding valve sleeve 3, and a rotary valve sleeve 4. In this embodiment, there are six pipes 1, combined with... Figure 9 and Figure 11 As shown, the end sleeve 2 is provided with six openings 23, and each pipe 1 is inserted into a different opening 23. The inner wall of the opening 23 is provided with a boss 231 to prevent the pipe 1 from passing through the other end of the opening 23.

[0043] like Figure 12 As shown, after all six pipes 1 are inserted into their respective openings 23, a sliding valve sleeve 3 is fitted onto the outside of the pipes 1. The sliding valve sleeve 3 has through holes 31 for the pipes 1 to pass through. One sliding valve sleeve 3 is provided on each control valve, corresponding to the number of pipes 1, and each sliding valve sleeve 3 has six through holes 31. In this embodiment, the movement of one sliding valve sleeve 3 can control the flow of fluid in the six pipes 1.

[0044] Then, the rotary valve sleeve 4 is fitted onto the end sleeve 2, at which point both the pipe 1 and the sliding valve sleeve 3 are located within the rotary valve sleeve 4. To ensure that the sliding valve sleeve 3 slides on the pipe 1 during the rotation of the rotary valve sleeve 4, guide mechanisms are provided on both the sliding valve sleeve 3 and the rotary valve sleeve 4. When the rotary valve sleeve 4 rotates, the guide mechanisms drive the sliding valve sleeve 3 to slide on the pipe 1, thereby controlling the opening and closing of the fluid passage within the control valve.

[0045] Finally, the other end sleeve 2 is fixed according to the position of the pipe 1. To ensure the overall structural strength of the control valve, both the end sleeve 2 and the sliding valve sleeve 3 are provided with mounting holes 71 for pressing and fixing the two end sleeves 2 together. In this embodiment, a mounting pin 72 is also included. The mounting pin 72 passes through the mounting hole 71 and presses the two end sleeves 2 together through a threaded engagement to prevent loosening inside the mechanical valve. In order to prevent large spectral distortion inside the mechanical valve, a silencer 721 is provided at the end of the mounting pin 71.

[0046] In this embodiment, to enable the sliding valve sleeve 3 to control the opening and closing of the pipeline 1, a block 11 is provided inside the pipeline 1. The block 11 is located in the middle of the pipeline 1, dividing the interior of the pipeline 1 into two non-communicating spaces. The pipeline 1 is also provided with several vent holes 12, which are respectively located on both sides of the block 11 and evenly distributed along the circumference of the pipeline 1. Correspondingly, as... Figure 5 As shown, a venting groove 32 is provided on the inner wall of the perforation 31. The venting groove 32 is an annular groove 611 arranged around the inner wall of the perforation 31. When the sliding valve sleeve 3 slides, it drives the venting groove 32 to cover or move away from the venting hole 12.

[0047] like Figure 4As shown, the guiding mechanism includes a groove 33 and a slider 41. The groove 33 is disposed on the outer surface of the sliding valve sleeve 3, and is elongated. The line connecting the two ends of the groove 33 is not parallel to the length direction of the pipe 1. The slider 41 is fixed on the inner surface of the rotary valve sleeve 4 and is located in the groove 33. When the rotary valve sleeve 4 rotates, the slider 41 on the rotary valve sleeve 4 drives the sliding valve sleeve 3 to slide. Figures 6 to 7 As shown, the slide groove 33 is inclined. When the rotary valve sleeve 4 rotates, the slider 41 inside the rotary valve sleeve 4 rotates on a cross section, but it can drive the slide groove 33 and the sliding valve sleeve 3 with the slide groove 33 to move relative to the pipeline 1.

[0048] Figure 6 and Figure 9 Correspondingly, at this time, the slider 41 is located at the end of the groove 33, and the sliding valve sleeve 3 is located at one end of the pipe 1. The vent holes 12 on both sides of the block 11 of the pipe 1 are not connected to each other, thus achieving fluid disconnection. Rotating the rotary valve sleeve 4 causes the sliding valve sleeve 3 to move, as... Figure 7 As shown, the sliding valve sleeve 3 is in motion at this time. When the rotating valve sleeve 4 is rotated to a certain extent, the slider 41 reaches the other end of the groove 33, as shown. Figure 8 As shown, at this time, the sliding valve sleeve 3 also reaches the other end of the pipe 1, as... Figure 10 As shown, at this time, the vent 12 is located in the vent groove 32, and the vent groove 32 enables the flow of fluid at both ends of the block 11.

[0049] In this embodiment, in order to increase the airtightness of the mechanical valve, gaskets are provided at the connection points between the end sleeve, the pipe, the sliding valve sleeve and the rotary valve sleeve, and two gaskets are provided at each connection point.

[0050] To prevent external forces from affecting the rotary valve sleeve 4, a limiting mechanism is provided between the end sleeve 2 and the rotary valve sleeve 4 to restrict the rotation of the rotary valve sleeve 4. For example... Figure 2 and Figure 3As shown, the limiting mechanism includes a fixing bolt 51, a limiting piece 52, and a limiting groove 42 formed on the rotary valve sleeve 4. The fixing bolt 51 is fixed to the end sleeve 2. The limiting end 521 of the limiting piece 52 is located in the limiting groove 42. The limiting piece 52 is sleeved on the fixing bolt 51 and can slide along the length direction of the fixing bolt 51. When the limiting piece 52 slides on the fixing bolt 51, the limiting end 521 moves in and out of the limiting groove 42. There are two limiting grooves 42, which are set at one end of the rotary valve sleeve 4. When the slider 41 slides from one end of the slide groove 33 to the other end of the slide groove 33, the limiting end 521 moves from one limiting groove 42 to the other limiting groove 42. The end sleeve 2, equipped with a limiting mechanism, has a slot 21. A fixing bolt 51 is located at the bottom of the slot 21, and a limiting groove 42 covers the slot 21. The fixing bolt 51 also has an elastic element 53, which is located between the bottom of the slot 21 and the limiting element. The limiting end 521 of the limiting element is positioned in the limiting groove 42 under the action of the elastic element 53. Pressing the limiting element compresses the elastic element 53, causing the limiting end 521 to move into the slot 21. Pressing the limiting element causes it to be pressed into the slot 21. After releasing, the limiting element returns to the limiting groove 42 under the action of the elastic element 53, achieving automatic reset without the need for secondary manual adjustment.

[0051] Generally, a connector 8 needs to be connected to the outer wall of the end sleeve 2 to facilitate the transportation of the corresponding fluid. In this embodiment, a pagoda connector 8 is used as an example. An internal thread can be directly provided in the opening 23 of the end sleeve 2, and an external thread can be provided at the connection end of the connector 8. The connector 8 and the end sleeve 2 are connected by a threaded engagement.

[0052] In this embodiment, a mechanical valve has multiple pipes 1, and screwing on the connectors 8 one by one is very time-consuming. Therefore, as Figure 13 and Figure 14 As shown, this embodiment also includes a connector for connecting to the external pipe 1. The connector includes a connector 61 and multiple connectors 62. The connector 61 is detachably fixed to the end sleeve 2. The end sleeve 2 is provided with a protrusion 22. The side of the connector 61 that is fixed to the end sleeve 2 is provided with an annular groove 611 that facilitates the insertion of the protrusion 22. A stop block 612 is provided on the groove wall of the annular groove 611. The end of the protrusion 22 is located in the sliding groove 33 and is locked in the sliding groove 33 by the stop block 612.

[0053] like Figure 15As shown, the connecting seat 61 includes a base plate 614 and a connecting ring 616. The base plate 614 has a through hole 615, and the connecting nozzle 62 is inserted into the through hole 615. To facilitate quick pairing of the connecting nozzle 62 with the corresponding opening 23, the base plate 614 is located in the middle of the connecting nozzle 62. The base plate 614, which has multiple connecting nozzles 62, is directly fixed to the end sleeve 2. The annular groove 611 is provided on the connecting ring 616, and the base plate 614 is located between the base plate 614 and the connecting ring 616. Then, the connecting ring 616 is fastened, and the connecting ring 616 is rotated to rotate the protrusion 22 into the groove bottom between the stop block 612 and the annular groove 611.

[0054] In order to prevent the connecting nozzle 62 from falling off the base plate 614, a detachable clamp 63 is provided on the outside of the connecting nozzle 62, which is fixedly located on one side of the base plate 614. A locking block 621 is provided on the other side of the connecting nozzle 62. The base plate 614 is located between the clamp 63 and the locking block 621, so the connection is stable.

[0055] Similar to rotary valves, in order to prevent external forces from affecting the connecting parts, the side of the connecting seat 61 is provided with a locking groove 613. The locking groove 613 is connected to the annular groove 611. One end of the limiting piece 52 is the limiting end 521, and the other end is the locking end 522. The locking end 522 is located in the locking groove 613 and moves in and out of the annular groove 611 under the action of external forces.

[0056] The above are preferred embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and these should also be considered within the scope of protection of the present invention.
