Description

Technical Field

[0001] The present invention relates to the technical field of valves, and particularly to a dynamic adjustment three-way valve. Background Art

[0002] A three-way valve is a control component in a fluid transportation system, with functions such as shut-off, adjustment, diversion, prevention of backflow, pressure stabilization, flow splitting or overflow. In a fluid transportation system, to keep the hydraulic balance of the system stable, the flow rate is changed by adjusting the opening degree of the valve, thereby achieving dynamic adjustment. The specific principle is as follows: When the working pressure changes, the opening degree of the throttle port decreases due to the fluctuation of the medium pressure; conversely, it increases. In this way, at a certain opening degree, the working pressure difference can be kept constant or a small negative pressure difference can be generated. This control method can eliminate the unstable factors in the system and make the system operate in a stable state.

[0003] However, there are still the following deficiencies in actual use: Most three-way valves that can change the flow rate by adjusting the opening degree of the valve are electrically controlled. In the case of water cut-off and power cut-off, such valves cannot be automatically closed, which is not reliable. Especially in the situation where water supply is restored but power supply is not restored, a water leakage accident will occur. If no one discovers it in time, it will not only cause unnecessary waste of water resources, but also there is a risk of damaging indoor electrical equipment and other items, resulting in property losses. Summary of the Invention

[0004] To solve the defects existing in the prior art, the present invention provides a dynamic adjustment three-way valve.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A dynamic adjustment three-way valve of the present invention includes a valve body. An inlet end cover and an outlet end cover are respectively provided at both ends of the valve body. An extension seat is provided at the top of the outlet end cover, and a tangential flow channel is arranged tangentially on the extension seat;

[0007] A water intercepting mechanism arranged in the outlet end cover, which includes a cam and a water intercepting plug. The water intercepting plug can be pushed by the cam to allow water to flow out of the outlet end cover;

[0008] A movable assembly for supporting the cam, which includes a transmission rod, and the cam is sleeved and fixed on the transmission rod;

[0009] A water power mechanism arranged above the cam, which includes a lifting assembly, a support housing installed at the top of the extension seat, an impeller arranged in the extension seat, and a power rod driven by the impeller. The water flowing out of the tangential flow channel acts tangentially on the impeller to make the impeller rotate.

[0010] As a preferred technical solution of the present invention, the power rod member includes a power rod located outside the support housing. One end of the power rod is provided with a transmission card slot, and the other end is provided with a connecting rod rotatably connected to the support housing. One end of the connecting rod is provided with a locking block, and a limiting rotation groove and a positioning guide groove communicating with the limiting rotation groove are also provided on the outer wall of the connecting rod. And the impeller is sleeved and fixed outside the power rod.

[0011] As a preferred technical solution of the present invention, the lifting assembly further includes a lifting cap located outside the support housing, a bowl-shaped diaphragm located inside the support housing, and a lifting rod for connecting the lifting cap and the bowl-shaped diaphragm. A locking card slot for engaging with the locking block is provided at the bottom of the lifting rod, and a through hole through which the lifting rod can pass is provided at the top of the support housing.

[0012] As a preferred technical solution of the present invention, the bowl-shaped diaphragm includes an annular fixing portion connected to the support housing and a reinforcing ring for installing the lifting rod. The annular fixing portion is connected to the reinforcing ring through an elastic portion.

[0013] As a preferred technical solution of the present invention, the movable assembly further includes a mounting seat penetrating through the bottom of the water outlet end cover and a torsion spring provided in the mounting seat. The torsion spring is used to connect the mounting seat and the transmission rod. The transmission rod is rotatably connected to the mounting seat, and a transmission block for engaging with the transmission card slot is provided at the top of the transmission rod.

[0014] As a preferred technical solution of the present invention, the water intercepting mechanism further includes a mounting frame provided in the water outlet end cover, a movable push plate in contact with the cam, and a push rod for connecting the water intercepting plug and the movable push plate. A support spring for connecting the movable push plate and the mounting frame is sleeved outside the push rod;

[0015] Both sides of the mounting frame are provided with positioning convex strips. One end of the mounting frame is provided with a sliding through hole through which the push rod can pass. Symmetric connecting screws are also provided at one end of the mounting frame. The connecting screws fix the mounting frame in the water outlet end cover through nuts, and the cam is provided inside the mounting frame.

[0016] As a preferred technical solution of the present invention, positioning sliding rails slidably matched with the positioning convex strips are provided on the inner wall of the water outlet end cover. A water outlet interface is communicated at one end of the water outlet end cover. An annular convex edge that can be closed by the water intercepting plug is also provided at the connection part of the water outlet end cover and the water outlet interface. A connection hole through which the connecting screw can pass is provided on the annular convex edge.

[0017] As a preferred technical solution of the present invention, one end of the tangential flow channel is communicated with the water outlet flow channel in the water outlet end cover through a guiding flow channel. The water outlet flow channel is communicated with the extension seat through a communication hole. The communication hole is in rotational fit with the power rod.

[0018] As a preferred technical solution of the present invention, an L-shaped limiting plate movably matched with the connecting rod through a limiting rotating groove and a positioning guide groove is arranged in the supporting shell, and a plurality of water through holes are further formed in the bottom of the supporting shell.

[0019] As a preferred technical solution of the present invention, two sealing valve seats arranged face to face are arranged in the valve body, a valve core is arranged between the two sealing valve seats, and a valve rod capable of extending outside the valve body and rotatably connected with the valve body is arranged at the top of the valve core.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. For this dynamic adjustment three-way valve, when the water supply and power are cut off, through the arranged movable assembly, lifting assembly and power lever, the water intercepting plug can be driven to close the annular convex edge. And after the water supply is restored first, if no one releases the locking of the power lever, the water flow will not be able to drive the impeller to rotate, and the water intercepting plug can still close the annular convex edge, ensuring that the valve can be reopened only when there is water and someone at the same time, effectively solving the problem of water leakage caused by the cut-off of water supply and power, and thus avoiding the waste of water resources and property losses caused by water leakage.

[0022] 2. For this dynamic adjustment three-way valve, the water flow acting tangentially on the impeller causes the impeller to rotate. The impeller drives the power rod to rotate, and the transmission rod drives the cam. The cam pushes the water intercepting plug away from the annular convex edge, and the water flow can normally flow out through the annular convex edge for normal water supply.

[0023] 3. For this dynamic adjustment three-way valve, when there is no water, since there is no water pressure to open the bowl-shaped diaphragm, even if someone lifts the lifting cap and then releases it, the elastic force of the bowl-shaped diaphragm will still drive the lifting rod to move into the supporting shell, making the locking block insert into the locking groove, and it is simply impossible to release the locking of the power lever. Therefore, even if the valve is forgotten to be closed, there will be no water leakage phenomenon.

[0024] 4. For this dynamic adjustment three-way valve, the connecting rod can be positioned by using the positioning guide groove and the L-shaped limiting plate. When the power rod rotates, the rotation angle of the power rod can be restricted by using the limiting rotating groove and the L-shaped limiting plate, making the operation of the valve more reliable.

[0025] 5. For this dynamic adjustment three-way valve, when the water intercepting plug closes the annular convex edge, the movable push plate is pressed by the supporting spring and the cam, so as to more reliably cut off the water flow.

[0026] 6. For this dynamic adjustment three-way valve, through the sliding fit of the positioning slide rail and the positioning convex strip, the installation frame is installed into the water outlet end cover, and the connecting screw can be aligned with the connecting hole. Therefore, after the connecting screw passes through the connecting hole, a nut can be used for fixation, which is convenient for assembly. Description of the Drawings

Specific embodiments

[0042] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0043] Embodiment: As Figures 1-5 shown, a dynamic adjustment three-way valve of the present invention includes a valve body 1. An inlet end cover 2 and an outlet end cover 3 are respectively provided at both ends of the valve body 1. An extension seat 32 is provided at the top of the outlet end cover 3, and a tangential flow channel 33 is arranged tangentially on the extension seat 32;

[0044] A water cutoff mechanism 8 arranged in the outlet end cover 3 includes a cam 88 and a water cutoff plug 83. The water cutoff plug 83 can be pushed by the cam 88 to allow water to flow out of the outlet end cover 3;

[0045] A movable assembly for supporting the cam 88 includes a transmission rod 10, and the cam 88 is sleeved and fixed on the transmission rod 10;

[0046] A water power mechanism 9 arranged above the cam 88 includes a lifting assembly, a support housing 91 installed on the top of the extension seat 32, an impeller 92 arranged in the extension seat 32, and a power rod member 93 driven by the impeller 92. The water flowing out of the tangential flow channel 33 acts tangentially on the impeller 92 to make the impeller 92 rotate.

[0047] In this embodiment, two water inlet interfaces 21 communicating with the water inlet end cover 2 are provided on the water inlet end cover 2, and water enters the valve from the water inlet interfaces 21.

[0048] In addition, a receiving groove for receiving the impeller 92 is provided on the extension seat 32, and the tangential flow channel 33 is arranged tangentially, which means that it is tangential to the receiving groove. The tangentially arranged tangential flow channel 33 enables water flowing out of the tangential flow channel 33 to act tangentially on the impeller 92, causing the impeller 92 to rotate.

[0049] It should be noted that a sealing ring, such as an O-ring, needs to be provided on the water cut-off plug 83 to improve the sealing performance.

[0050] Among them, Figures 2-4 and Figures 6-9 As shown, the power rod 93 includes a power rod 931 located outside the support shell 91, a transmission slot 935 is provided at one end of the power rod 931, and a connecting rod 932 rotatably connected to the support shell 91 is provided at the other end, a locking block 936 is provided at one end of the connecting rod 932, and a limited rotation groove 934 and a positioning guide groove 933 connected to the limited rotation groove 934 are also provided on the outer wall of the connecting rod 932, and the impeller 92 is sleeved and fixed outside the power rod 931.

[0051] In this embodiment, a mounting hole capable of accommodating the connecting rod 932 is provided at the bottom center of the support shell 91, and a bearing mounting groove 913 for installing a bearing is provided at the bottom of the mounting hole. The connecting rod 932 is rotatably connected to the support shell 91 through the bearing.

[0052] The water flow acting tangentially on the impeller 92 causes the impeller 92 to rotate, and the impeller 92 drives the power rod 931 to rotate. The transmission rod 10 drives the cam 88 to rotate 90°, and the water cut-off plug 83 is pushed away from the annular ridge 34 by the cam 88, so that the water flow can flow out through the annular ridge 34 normally.

[0053] Among them, Figure 7 and Figure 8 As shown, the lifting assembly also includes a lifting cap 95 located outside the supporting shell 91, a bowl-shaped diaphragm 96 arranged inside the supporting shell 91, and a lifting rod 94 for connecting the lifting cap 95 and the bowl-shaped diaphragm 96, and a locking slot 941 engaged with the locking block 936 is provided at the bottom of the lifting rod 94, and a through hole capable of accommodating the lifting rod 94 to pass through is provided at the top of the supporting shell 91.

[0054] When there is no water, there is no water to provide pressure to open the bowl-shaped diaphragm 96. Therefore, after the lifting cap 95 is lifted and then released, the elastic force of the bowl-shaped diaphragm 96 will still drive the lifting rod 94 to move into the supporting shell 91, so that the locking block 936 is inserted into the locking slot 941, and the power rod 93 cannot be unlocked at all;

[0055] After the water supply is restored, the lifting cap 95 can be lifted by hand to open the bowl-shaped diaphragm 96. At the same time, the lifting cap 95 drives the lifting rod 94 to move into the support housing 91, so that the locking block 936 disengages from the locking groove 941, releasing the lock on the power rod 93. After that, the impeller 92 can drive the power rod 931 to rotate. At this time, the bowl-shaped diaphragm 96 will open under the action of water pressure, and the lifting rod 94 will be supported by the opened bowl-shaped diaphragm 96, completely releasing the lock on the power rod 93.

[0056] Among them, as Figure 7 , Figure 8 and Figure 10 shown, the bowl-shaped diaphragm 96 includes an annular fixing portion 962 connected to the support housing 91 and a reinforcing ring 963 for installing the lifting rod 94. The annular fixing portion 962 is connected to the reinforcing ring 963 through an elastic portion 961. Figure 7 The bowl-shaped diaphragm 96 in Figure 8 is in the original state, and the bowl-shaped diaphragm 96 in

[0057] is in the open state. When the bowl-shaped diaphragm 96 is in the open state, the elastic portion 961 deforms; the provided bowl-shaped diaphragm 96 can not only drive the lifting rod 94, but also separate the water, effectively preventing water from flowing out through the gap between the lifting rod 94 and the support housing 91, and can also reduce the sealing difficulty between the lifting rod 94 and the support housing 91. Figure 3 and Figure 4 shown, the movable assembly further includes a mounting seat 7 penetrating through the bottom of the water outlet end cover 3 and a torsion spring provided in the mounting seat 7. The torsion spring is used to connect the mounting seat 7 and the transmission rod 10. The transmission rod 10 is rotatably connected to the mounting seat 7, and a transmission block 101 engaged with the transmission slot 935 is provided at the top of the transmission rod 10.

[0058] In this embodiment, a mounting hole capable of accommodating the transmission rod 10 is provided at the top of the mounting seat 7, and the transmission rod 10 is rotatably connected to the mounting seat 7 through a bearing.

[0059] By using the engagement of the transmission block 101 and the transmission slot 935, the connection between the transmission rod 10 and the power rod 931 is realized. Therefore, when the power rod 931 rotates, it can drive the transmission rod 10, and drive the cam 88 through the transmission rod 10. When the transmission rod 10 drives the cam 88, the torsion spring deforms. When the water supply stops and the water pressure is insufficient or there is no water, the elastic force of the torsion spring will drive the transmission rod 10 to rotate reversely by 90°, and drive the power rod 931 to rotate by 90° through the transmission rod 10, so that the cam 88 returns to its original position (the short end of the cam 88 contacts the movable push plate 87).

[0060] Among them, as Figures 2-4As shown, the water cutoff mechanism 8 further includes a mounting frame 81 disposed inside the water outlet end cover 3, a movable push plate 87 in contact with the cam 88, and a push rod 82 for connecting the water cutoff plug 83 and the movable push plate 87. A support spring 86 for connecting the movable push plate 87 and the mounting frame 81 is sleeved outside the push rod 82;

[0061] Positioning ridges 84 are provided on both sides of the mounting frame 81. A sliding through hole through which the push rod 82 can pass is opened at one end of the mounting frame 81. Connecting screws 85 are symmetrically provided at one end of the mounting frame 81. The mounting frame 81 is fixed inside the water outlet end cover 3 by nuts through the connecting screws 85. The cam 88 is disposed inside the mounting frame 81. The presence of the mounting frame 81 can effectively block the impact of water flow on the cam 88.

[0062] In this embodiment, the movable push plate 87 is pressed by the support spring 86 and the cam 88, so that the water flow can be cut off more reliably.

[0063] The cam 88 pushes the movable push plate 87 to squeeze the support spring 86. The movable push plate 87 drives the push rod 82. Cooperating with the water flow acting on the movable push plate 87, the water cutoff plug 83 can be smoothly pushed away from the annular flange 34, so that the water flow can normally flow out through the annular flange 34. When the water supply stops, resulting in insufficient water pressure or even no water, the cam 88 returns to its original position. At this time, the movable push plate 87 returns to its original position under the drive of the support spring 86, and the annular flange 34 is closed by the water cutoff plug 83.

[0064] Among them, as Figure 4 and Figure 5 shown, positioning slide rails 36 that are slidably matched with the positioning ridges 84 are provided on the inner wall of the water outlet end cover 3. A water outlet interface 31 is connected and provided at one end of the water outlet end cover 3. An annular flange 34 that can be closed by the water cutoff plug 83 is further provided at the connection between the water outlet end cover 3 and the water outlet interface 31. A connection hole 37 through which the connecting screw 85 can pass is opened on the annular flange 34.

[0065] Through the sliding fit between the positioning slide rails 36 and the positioning ridges 84, the mounting frame 81 is installed in the water outlet end cover 3, and the connecting screw 85 can be aligned with the connection hole 37. Therefore, after the connecting screw 85 passes through the connection hole 37, nuts can be used for fixation, which is convenient for assembly.

[0066] Among them, as Figure 4 and Figure 5 shown, one end of the tangential flow channel 33 is connected and communicated with the water outlet flow channel inside the water outlet end cover 3 through the guiding flow channel 35. The water outlet flow channel is connected and communicated with the extension base 32 through a communication hole. The communication hole is rotationally matched with the power rod 931. After the water enters the guiding flow channel 35, the pressure and speed of the water flow can be increased, which is more beneficial to the rotation of the impeller 92.

[0067] Among them, asFigures 11-13 As shown, an L-shaped limiting plate 911 is arranged in the support housing 91 and is movably matched with a connecting rod 932 through a limiting rotating groove 934 and a positioning guide groove 933. A plurality of water through holes 912 are further formed at the bottom of the support housing 91. The existence of the water through holes 912 can enable water to flow through, avoiding excessive water pressure inside the support housing 91. The positioning guide groove 933 and the L-shaped limiting plate 911 can position the connecting rod 932. When the power rod 931 rotates, the limiting rotating groove 934 and the L-shaped limiting plate 911 can limit the rotation angle of the power rod 931, enabling the power rod 931 to only rotate forward or backward by 90°, so that the cam 88 can also only rotate forward or backward by 90°.

[0068] Among them, as Figure 2 shown, two sealing valve seats 6 are arranged in the valve body 1 in a face-to-face manner. A valve core 4 is arranged between the two sealing valve seats 6. A valve rod 5 is arranged at the top of the valve core 4 and can extend outside the valve body 1 and is rotatably connected to the valve body 1. The sealing valve seats 6 play a sealing role and can prevent water leakage. The valve rod 5 is used to connect with electric control devices such as motors and can realize flow control by changing the opening degree of the valve core 4.

[0069] During operation, during normal water supply, the valve rod 5 drives the valve core 4 to control the opening and closing of the valve and the flow regulation. After the water supply and power supply are cut off, due to the elastic force of the torsion spring, the drive rod 10 will rotate reversely by 90°. The drive rod 10 drives the cam 88 to rotate by 90°. Driven by the elastic force of the support spring 86, the movable push plate 87 will drive the water cut-off plug 83 to seal the annular convex edge 34 through the push rod 82. The bowl-shaped diaphragm 96 also returns to its original state due to the absence of water (or too low water pressure). Driven by the elastic force of the bowl-shaped diaphragm 96, the lifting rod 94 moves into the support housing 91, so that the locking block 936 is inserted into the locking slot 941 to lock the power rod member 93.

[0070] After the water supply is restored, the water flows through the guiding flow channel 35, is pressurized and accelerated, and then acts tangentially on the impeller 92. However, since the locking of the power rod member 93 is not released, the water flow cannot make the impeller 92 rotate, and the water cut-off plug 83 can still seal the annular convex edge 34, preventing the water from flowing out. After lifting the lifting cap 95, the locking block 936 can be disengaged from the locking slot 941, and the locking of the power rod member 93 can be released. Then, the impeller 92 can drive the power rod member 93 to rotate by 90° under the action of the water flow. The power rod member 93 drives the cam 88, and the cam 88 and the water flow acting on the movable push plate 87 can push the water cut-off plug 83 away from the annular convex edge 34, and the water flow can flow out through the annular convex edge 34 normally.

[0071] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
