Referring to fig. 1-6, fig. 1-6 are schematic structural views of a regulator valve assembly according to an embodiment of the present invention.
The regulating valve assembly comprises a movable rod 1, a pressure unit and a guide unit, wherein the guide unit comprises a switch waterway a, a first waterway b and a second waterway c, the pressure unit is used for applying a preset pressure to the movable rod 1, and the movable rod 1 is used for plugging or opening the second waterway c;
when the water pressure is lower than the preset pressure, the movable rod 1 plugs the second waterway c, and the first waterway b discharges water;
when the water pressure exceeds the preset pressure, the water outlet of the switch waterway a drives the movable rod 1 to open the second waterway c, and the first waterway b and the second waterway c are used for discharging water simultaneously.
In this embodiment, when the water pressure is lower than the preset pressure, the water outlet of the switch waterway a is insufficient to overcome the preset pressure applied to the movable rod 1 by the pressure unit, the water outlet cannot push the movable rod 1, the movable rod 1 plugs the second waterway c at this time, and only the first waterway b is discharged outwards; when the water pressure exceeds the preset pressure, the water outlet of the switch waterway a pushes the movable rod 1, the movable rod 1 opens the second waterway c, and at the moment, the first waterway b and the second waterway c simultaneously outlet water. When the regulating valve assembly in the embodiment is at low pressure, only one water outlet path is used for discharging water outwards, so that the flow is small; and at high pressure, the other water outlet path is opened, and the flow is increased. Therefore, the embodiment can keep proper water outlet pressure under high and low water pressure, and good shower experience is brought.
Specifically, as shown in fig. 2, the movable bar 1 includes a center bar 11 and a tray 12, the tray 12 is fixed to the middle of the center bar 11, a switch waterway a is opened to the bottom surface of the tray 12, and the lower part of the center bar 11 is inserted into the guide unit.
The central rod 11 is a cylindrical rod, as shown in fig. 2 and 6, the central rod 11 is provided with an axial air hole 111 along a central axis, and the upper portion of the central rod 11 is further provided with a radial air hole 112, and the axial air hole 111 is perpendicular to and communicated with the radial air hole 112.
As shown in fig. 6, since the sleeve 5 is covered on the upper portion of the movable rod 1 and sealed by the first sealing ring 13, the purpose of the axial air holes 111 and the radial air holes 112 is to prevent air pressure variation in the space between the sleeve 5 and the upper portion of the movable rod 1 when the movable rod 1 moves up and down, thereby affecting the up and down movement of the movable rod 1. The space between the sleeve 5 and the upper portion of the movable rod 1 is communicated with the outside atmosphere through the axial air holes 111 and the radial air holes 112, and the movement of the movable rod 1 is not affected.
The sleeve 5, as well as the connection and movement between the sleeve 5 and the movable rod 1, will be described in detail later.
As shown in fig. 2 and 6, the tray 12 is a circular tray with a circular cross section and a U-shaped longitudinal section, and the bottom plate of the tray 12 is fixedly connected with or integrally formed with the middle part of the central rod 11. A space is left between the tray 12 and the upper portion of the central rod 11. The bottom surface of the bottom plate of the tray 12 corresponds to the switch waterway a, and the waterway of the switch waterway a acts on the bottom surface of the tray 12 after flowing out. When the water pressure is low, the preset pressure of the pressure unit is not exceeded, and the water flow is insufficient to push up the tray 12; when the water pressure is high, the water flow pushes up the tray 12, and the entire movable rod 1 pushes up, opening the second waterway c, exceeding the preset pressure of the pressure unit.
The outer side wall of the tray 12 is also sleeved with a first sealing ring 13, as shown in fig. 6, the outer side wall of the tray 12 contacts with the inner side wall of the sleeve 5, the first sealing ring 13 plays a role in sealing, water at the bottom plate of the tray 12 is prevented from entering the space between the sleeve 5 and the upper part of the movable rod 1,
further, as shown in fig. 1 and 6, the pressure unit is a spring 2, and the spring 2 is sleeved on the upper portion of the central rod 11 and is located in the tray 12.
The spring 2 applies certain preset pressure to the movable rod 1, so that the movable rod 1 blocks the second waterway c. When the water pressure increases, the movable rod 1 is pushed upwards to open the second waterway c when the water outlet of the switch waterway a overcomes the preset pressure.
Specifically, as shown in fig. 6, the top end of the spring 2 abuts on the sleeve 5, and the bottom end of the spring 2 abuts on the upper surface of the tray 12.
Alternatively, other pressure units can be used to preset the pressure on the movable rod 1.
Further, as shown in fig. 1 and fig. 3-6, the guiding unit includes a guiding block 3 and a supporting seat 4, the guiding block 3 is fixedly connected with the supporting seat 4, a first central hole 31 and a water outlet hole 32 are formed in the guiding block 3, a second central hole 41 and a U-shaped hole 42 are formed in the supporting seat 4, the first central hole 31 and the second central hole 41 are located on the same central axis, the lower portion of the central rod 11 is inserted into the first central hole 31 and the second central hole 41, the U-shaped hole 42 includes a water inlet end 421 and a water outlet end 422, and the water outlet end 422 of the U-shaped hole 42 is butted with the water outlet hole 32 to form a switch waterway a.
Wherein, as shown in fig. 3 and 6, the guide block 3 further includes a first boss 33, the first boss 33 is located on the upper surface of the guide block 3, and the first boss 33 is used for extending into the bottom surface of the tray 12 to be positioned with the tray 12. The guide block 3 is fixed on the supporting seat 4, and the supporting seat 4 is fixedly connected with the sleeve 5. When in work, the sleeve 5, the supporting seat 4 and the guide block 3 are all motionless, and only the movable rod 1 moves up and down. The guide block 3 is oblate and is provided with threads on the circumferential surface and is in threaded connection with the sinking pit 45 of the supporting seat 4. The first boss 33 is provided with a cutting plane, so that a tool can be conveniently clamped on the cutting plane, and the guide block 3 is driven to rotate and is connected with the supporting seat 4. Four water outlet holes 32 are uniformly arranged on the upper end surface of the guide block 3 at intervals, and the water outlet holes 32 are communicated with the U-shaped holes 42 on the supporting seat 4 correspondingly to form a switch waterway a (see fig. 13). The water outlet 32 corresponds exactly to the bottom surface of the tray 12.
In this embodiment, the central axis of one of the water outlet holes 32 is not necessarily aligned with the central axis of the water outlet end 422 of the U-shaped hole 42. Since the guide block 3 is in threaded connection with the supporting seat 4, no sealing element is arranged between the guide block 3 and the supporting seat 4, a tiny gap is arranged between the bottom surface of the guide block 3 and the supporting seat 4, and water flows out from the water outlet end 422, enters the gap, and then flows out from the four water outlet holes 32 respectively to enter the bottom surface of the tray 12.
Alternatively, only one water outlet 32 may be formed in the guide block 3, and the water outlet 32 is aligned with the water outlet 422, i.e. located on the same central axis. After exiting the water outlet 422, the water enters the water outlet 32 directly.
Further, as shown in fig. 4 to 6, the support base 4 further includes a notch portion 43, a first water path b (see fig. 14 to 15) is formed in the notch portion 43, and a second water path c (see fig. 15) is formed in the notch portion 43 when the movable lever 1 is lifted up.
Specifically, as shown in fig. 4, the supporting seat 4 further includes an oblate seat 46, a second boss 44 is disposed on an upper end surface of the seat 46, and a pit 45 is formed on the second boss 44. The water inlet end 421 of the U-shaped hole 42 is positioned outside the sinking pit 45 and the upper end face of the base 46, and the water outlet end 422 is positioned in the sinking pit 45. The sinking pit 45 is used for installing the guide block 3, and the outer circumferential surface of the guide block 3 is in threaded connection with the inner circumferential surface of the sinking pit 45. After the guide block 3 is fixed in the pit 45, the first central hole 31 and the second central hole 41 are exactly located on the same central axis. As shown in fig. 5, the lower end surface of the seat 46 is further provided with a convex ring 47, the convex ring 47 extends downwards from the lower end surface to form a circle of circular ring, and the center of the convex ring 47 is a cavity.
The notch 43 is formed in the seat 46 and the collar 47, and since the diameter of the collar 46 is smaller than the diameter of the seat 46, the notch depth of the notch 43 is stepwise changed from the seat 46 to the collar 47.
Further, as shown in fig. 1 and 6, the adjusting valve assembly further includes a sleeve 5, the sleeve 5 is at least sleeved outside the tray 12, the sleeve 5 is fixedly connected with the supporting seat 4, and an inner side wall of the sleeve 5 is slidably connected with an outer side wall of the tray 12.
Specifically, the inner side wall of the sleeve 5 is in threaded connection with the second boss 44 of the supporting seat 4, and the inner wall surface of the seat body 46 provided with the second central hole 41 is provided with a third sealing ring 48, and the third sealing ring 48 plays a role in sealing the central rod 11, but does not influence the central rod 11 to move up and down in the second central hole 41.
Further, as shown in fig. 1 and 6, the regulator valve assembly further includes a housing 6, and an inner wall surface of the housing 6 and an outer wall surface of the sleeve 5 form a water inlet passage d (see fig. 13) that communicates with the U-shaped hole 42 and the notch portion 43.
Specifically, the top opening of the casing 6 may be connected to a water pipe, and after water enters from the top of the casing 6, the water passes through a gap between the sleeve 5 and the casing 6, and the gap is a water inlet channel d. Since the sleeve 5 is covered outside the second boss 44 of the support base 4, the water inlet end 421 of the U-shaped hole 42 is located at the outer ring of the second boss 44, and the notch 43 is also located at the outer ring of the second boss 44. Therefore, the water in the water inlet channel d can enter the water inlet end 421 and also can enter the notch part 43, and can enter the hollow space of the convex ring 47 through the notch part 43. When the movable rod 1 is not lifted, only the first waterway b is arranged in the notch part 43, and when the movable rod 2 is lifted, the second waterway c is opened, and the first waterway b and the second waterway c are simultaneously arranged in the notch part 43. The orientation of each waterway will be described in detail later.
In the present embodiment, at low water pressure, water enters the bottom surface of the tray 12 from the water inlet passage d through the U-shaped hole 42, but the water flows in from the notch portion 43 and then flows out through the first waterway b because the water pressure is too low to push the movable lever 1. At this time, the flow rate of water is small under low pressure, and a certain water outlet pressure can be maintained.
At high water pressure, water enters the bottom surface of the tray 12 from the water inlet channel d through the U-shaped hole 42, pushes the tray 12 to move upwards, drives the whole movable rod 1 to lift up, and opens the second waterway c. Accordingly, water enters the notch 43 from the water inlet passage d and flows out through the first water passage b and the second water passage c at the same time. At this time, the flow rate of water is also large at high pressure, and the proper water outlet pressure is maintained.

The positioning block 77 corresponds to the notch 43 of the support base 4. The positioning block 77 is inserted into the notch part 43 to position the supporting seat 4 and the sinking table 76, so that the adjusting valve assembly is conveniently mounted on the upper cover 7. As shown in fig. 14, after water enters the notch 43 from the water inlet passage d, the water flows out through the side hole 71, and the first water passage b is provided between the notch 43 and the side hole 71. As shown in fig. 11, the side holes 71 extend into the first partition a of the bottom surface of the upper cover 7, and the side holes 71 guide the water in the first water path b into the first partition a, and the first partition a corresponds to the corresponding number of nozzles 81 on the lower cover 8. As can be seen from fig. 11, the first partition a occupies only a part of the upper cover 7, so that the final water yield from the first waterway b to the nozzle 81 is small.
At low water pressure, as shown in fig. 13, the bottom end of the center rod 11 is inserted into the third center hole 72, thus blocking the second waterway c. As shown in fig. 15, when the water pressure is high, the center rod 11 is lifted, i.e., comes out of the third center hole 72, the second water path c is opened, and water enters into the third center hole 72 from the notch portion 43. As shown in fig. 11, a third central hole 72 opens into the bottom surface of the upper cover 7, and water is introduced into the second partition B through a water diversion passage 74. As can be seen in fig. 11, a second section B is located at the periphery of the first section a, which also corresponds to part of the nozzles 81 on the lower cover 8. Thus, at high pressure, two subareas corresponding to the two waterways spray water simultaneously, and the water yield is increased.
As shown in fig. 9 and 11, the flange 73 is a boundary forming the first partition a, the flange 73 extends downward from the bottom surface of the upper cover 7, and the bottom of the flange 73 contacts the lower cover 8. The flanges 73 are formed in a fan shape and symmetrically distributed on opposite sides of the third central hole 72, and each corresponds to one of the side holes 71. A water diversion channel 74 is formed between the two flanges 73. Between the periphery of the flange 73 and the edge of the upper cover 7 is a second partition B which communicates with the third central hole 72 through a water channel 74.
Alternatively, a flange 73 may be provided on the lower cover 8, the flange 73 extending upward from the upper surface of the lower cover 8, the top portion being in contact with the bottom surface of the upper cover 7. The flange 73 may directly divide the plurality of nozzles 81 on the lower cover 8 into two parts.
Further, as shown in fig. 8 and 12, the upper cover 7 is further provided with mounting holes 75, and the corresponding lower cover 8 is also provided with mounting holes, which are connected by bolts 82.
The working procedure of this embodiment is as follows:
at low water pressure, as shown in fig. 13, water enters the bottom surface of the tray 12 from the water inlet passage d through the U-shaped hole 42, but is insufficient to push the movable lever 1 due to the water pressure being too low. Accordingly, as shown in fig. 14, water enters the notch 43 from the water inlet passage d, passes through the first water passage b, and enters the side hole 71. As shown in fig. 16, the water enters the first partition a from the side hole 71, and the water outlet range of the first partition a is shown in fig. 16. At this time, although the inflow water is at a low water pressure, the outflow water flow rate is small, and therefore a constant outflow water pressure can be maintained.
As shown in fig. 15, when the water pressure is high, water enters the bottom surface of the tray 12 from the water inlet channel d through the U-shaped hole 42, pushes the tray 12 to move upwards, drives the whole movable rod 1 to lift, and opens the second waterway c after the movable rod 1 is pulled out from the third central hole 72. Accordingly, water enters the notch 43 from the water inlet passage d and flows out through the first water passage b and the second water passage c at the same time. As shown in fig. 17, water simultaneously enters the second partition B from the third center hole 72, and enters the first partition a from the side hole 71, and the water outlet range of the first partition a and the second partition B for simultaneously discharging water is shown in fig. 17. At this time, the water inlet is high in water pressure, the flow rate of the water is large, and the proper water outlet pressure is kept.
The regulating valve assembly is not limited to be used for a shower head, and can be used for other water outlet equipment which needs to regulate the flow according to the water pressure of water inlet.
What has been described above is merely illustrative of the principles and preferred embodiments of the present invention. It should be noted that several other variants are possible to those skilled in the art on the basis of the principle of the invention and should also be considered as the scope of protection of the present invention.
