Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.
As shown in fig. 1 to 3, fig. 1 is a schematic view showing a viewing angle of a water discharge valve according to a first embodiment of the present invention. Fig. 2 is a schematic view showing another perspective of the water discharge valve according to the first embodiment of the present invention. Fig. 3 shows an exploded view of the water discharge valve according to the first embodiment of the present invention.
The drain valve of the embodiment of the invention comprises: housing 100 and hinge 800.
The housing 100 defines an inlet passage 101, an outlet passage 102, and a drain passage 103 communicating with each other. In a specific embodiment, the housing 100 includes a valve body 100a and a valve seat 100b, and the valve body 100a and the valve seat 100b are removably coupled, such as a snap-fit connection or a threaded connection. The water inlet passage 101 may be provided in the valve body 100a, and the water outlet passage 102 and the water discharge passage 103 may be provided in the valve seat 100b, but not limited thereto.
The drain valve further includes a sealing ring 510 and a sealing ring 520, and the sealing ring 510 and the sealing ring 520 may be fitted around the valve seat 100 b. When the valve is positioned within a water supply pipe, the sealing rings 510 and 520 serve to seal the valve and pipe wall so that water flows only through the inlet passage 101 and does not flow along the gap between the valve and pipe wall.
The movable member 800 is movably disposed in the housing 100 to selectively block the drainage passage 103. When the movable piece 800 is driven by the water flow pressure to start moving and the water inlet channel 101 is not completely opened, the movable piece 800 blocks the water outlet channel 103.
The movable member 800 includes the valve cartridge 200, the first sealing member 310, and the elastic member 400. The valve cartridge 200 is movably disposed within the housing 100 and is capable of cooperating with the first seal 310 such that the first seal 310 selectively blocks the drain passage 103.
The elastic member 400 is disposed in the housing 100 to provide an elastic force to the valve cartridge 200, so that the valve cartridge has a tendency to move toward the initial position. Wherein, when the valve core 200 is driven by the water flow pressure to move from the initial position and the water inlet passage 101 is not completely opened, the first sealing member 310 blocks the water outlet passage 103.
It should be noted that the initial position of the valve cartridge 200 may be understood as the position of the valve cartridge 200 when the valve cartridge 200 is not subjected to the water flow pressure. When the valve cartridge 200 is in the initial position, the first elastic member 310 does not block the drain passage 103. Meanwhile, when the valve cartridge 200 is in the initial position, the valve cartridge 200 does not block the drain passage 103.
Of course, it is understood that moveable member 800 may also be made of a rubber material. The moving member 800 made of a rubber material may play a role of blocking the drainage passage 103, and may have elasticity itself, so that when the moving member 800 is not subjected to the pressure of the water flow, it may be restored to an initial position by the elasticity itself.
As shown in fig. 4, fig. 4 is a schematic view showing a valve body according to a first embodiment of the present invention. The valve body 100a includes a second chamber 120, one end of the second chamber 120 is provided with a second opening 121, and the second chamber 120 is communicated with the water inlet passage 101. The valve spool 200 is movably accommodated in the second chamber 120 in the axial direction of the valve body 100a through the second opening 121.
The valve body 100a further includes a guide post 130, and the guide post 130 extends in an axial direction of the valve body 100a to cooperate with the guide hole 220 of the valve spool 200 to guide the movement of the valve spool 200 with respect to the valve body 100 a.
As shown in fig. 5, fig. 5 is a schematic view showing a valve cartridge according to a first embodiment of the present invention. The first sealing member 310 may be a ring-shaped structure, and the first sealing member 310 is sleeved outside the valve core 200. When the valve core 200 moves relative to the housing 100, the first sealing member 310 can be moved.
One end of the valve element 200 is provided with a sealing portion 210, and the sealing portion 210 has a water inlet end surface 211. The water flow can be flushed to the water inlet end surface 211 after entering the water inlet channel 101.
As shown in fig. 6 and 7, fig. 6 is a schematic view showing a valve seat according to a first embodiment of the present invention. Fig. 7 shows a cross-sectional view of a valve seat according to a first embodiment of the invention. The valve seat 100b includes a first chamber 110, and the drain passage 103 communicates with the first chamber 110. The first cavity 110 has a first opening 111. The valve spool 200 is movably connected to the first chamber 110 through the first opening 111, so that the first sealing member 310 slidably abuts against an inner wall surface of the first chamber 110 to block the drain passage 103.
As shown in fig. 8 to 10 and 21 to 23, fig. 8 to 10 are sectional views showing the water discharge valve in a first embodiment of the present invention in different states. Fig. 21 to 23 are sectional views showing the water discharge valve in a shower head according to the first embodiment of the present invention in different states.
As shown in fig. 8 and 21, fig. 8 is a sectional view illustrating a valve cartridge 200 of a water discharge valve according to an embodiment of the present invention in an initial position. The valve body 100a and the valve seat 100b are coupled to each other and movably define the valve cartridge 200 in a cavity formed by the valve body 100a and the valve seat 100 b.
In one embodiment, the valve element 200 is capable of reciprocating along the axial direction of the valve body 100a and the valve seat 100 b.
The elastic member 400, which may be a compression spring, is disposed in the first cavity 110 of the valve seat 100 b. One end of the elastic element 400 abuts against the valve seat 100b, and the other end abuts against the valve element 200, so that the valve element 200 has a tendency to move to the initial position. In other words, when the water supply is stopped, the valve cartridge 200 is returned to the original position by the elastic member 400.
When the valve core 200 is at the initial position, that is, when no water flows into the water inlet channel 101, the first sealing member 310 sleeved outside the valve core 200 does not slidably contact with the inner wall surface of the first cavity 110, so the first sealing member 310 does not block the water outlet channel 103. At this time, water flow (e.g., water flow in the shower head 900) in the outlet passage 102 or downstream of the outlet passage 102 is siphoned out of the drain valve (e.g., in the direction of the arrows in fig. 8 and 21) along the drain passage 103, and the shower head 900 is drained from the drain hole 910 of the shower head 900. Make like this water installation, the water spout of a gondola water faucet for example can in time discharge the residual water, can not appear dripping the problem of residual water for a long time.
As shown in fig. 9 and 22, fig. 9 is a sectional view showing a water discharge valve according to an embodiment of the present invention in a state of water supply instant. The valve body 100a has a second chamber 120, and the second chamber 120 communicates with the water inlet passage 101 and has a second opening 121. The valve spool 200 is movably disposed in the second chamber 120 through the second opening 121. When the sealing portion 210 is disposed in the second cavity 120, a gap 610 is formed between an outer circumferential surface of the sealing portion 210 and an inner wall surface of the second cavity 120. Because the gap 610 is small, a very small portion of the water flow will flow through the gap 610 to the outlet channel 102 at the moment of water flowing, and a large portion of the water flow will be collected in the second chamber 120. Therefore, the water inlet end surface 211 of the sealing portion 210 and the inner wall surface of the second cavity 120 can form an energy storage cavity 122, and the energy storage cavity 122 can accumulate the water flow pressure entering the energy storage cavity. Since the pressure in the energy storage chamber 122 is close to the static pressure state, the valve core 200 can be driven to move even in a low water pressure state, so that the water inlet passage 101 can be quickly opened, and normal operation can be realized under extremely low water pressure.
With reference to fig. 9, since the first sealing member 310 can slidably abut against the inner wall surface of the first cavity 110 to achieve sealing, when the valve element 200 is driven by the water flow pressure to move from the initial position and the water inlet channel 101 is not completely opened, the first sealing member 310 already blocks the water outlet channel 103. Therefore, before the water inlet passage 101 is fully opened, the drain passage 103 is closed so that water does not flow out of the drain hole 910 of the shower head 900 through the drain passage 103, so that water leakage from the drain passage 103 under a low water pressure can be prevented.
As shown in fig. 10 and 23, the valve cartridge 200 is moved toward the valve seat 100b against the elastic force of the elastic member 400 by the accumulated pressure to completely open the water inlet passage 101. At the same time, the first seal 310 slides along the inner wall surface of the first cavity 110, and always closes the drainage passage 103.
In one embodiment, the first seal 310 may be a Y-ring seal. Because the Y-shaped sealing ring has the groove, when the first sealing element 310 is in slidable contact with the inner wall surface of the first cavity 110, the groove can make the Y-shaped sealing ring deform inward more easily, so that the friction between the first sealing element 310 and the inner wall surface of the first cavity 110 can be reduced, the valve element 200 can move more smoothly, and the effect of normal use under low water pressure is achieved.
With continued reference to fig. 10, the housing 100 includes a guide post 130, for example, the guide post 130 may be disposed on the valve seat 100 b. The valve core 200 has a guide hole 220 to be fitted with the guide post 130. The guide post 130 and the guide hole 220 can guide the movement of the valve cartridge 200 when the valve cartridge 200 moves with respect to the housing 100.
As shown in fig. 11 to 17, fig. 11 is a schematic view showing a viewing angle of a water discharge valve according to a second embodiment of the present invention. Fig. 12 is a schematic view showing another perspective of a water discharge valve according to a second embodiment of the present invention. Fig. 13 is an exploded view showing a water discharge valve according to a second embodiment of the present invention. Figure 14 shows a schematic view of a valve cartridge according to a second embodiment of the invention. Figure 15 shows a cross-sectional view of a valve cartridge according to a second embodiment of the present invention. Figure 16 shows a schematic view of a valve seat according to a second embodiment of the invention. Fig. 17 shows a cross-sectional view of a valve seat according to a second embodiment of the invention.
The drain valve of the second embodiment of the present invention has the same structure as the drain valve of the first embodiment, and the difference is that: the hinge 800 of the second embodiment of the present invention further includes a second seal 320. The valve cartridge 200 can cooperate with the second seal 320 such that the second seal 320 selectively blocks the water inlet passage 101.
Specifically, as shown in fig. 13 to 15 and 18 to 20, the second sealing member 320 is sleeved on the outer periphery of the valve element 200 and can move along with the valve element 200. The second seal 320 and the first seal 310 are spaced apart along the axial direction of the valve cartridge 200.
When the valve core 200 moves relative to the second cavity 120, the second sealing member 320 can abut against the inner wall surface of the second cavity 120 in a sliding manner, so that the water inlet passage 101 can be selectively blocked.
As shown in fig. 18, the valve cartridge 200 is in an initial position by the elastic member 400. At this time, the second sealing member 320 abuts against the inner wall surface of the second chamber 120, so that the second sealing member 320 blocks the water inlet passage 101. At this time, the first seal member 310 does not block the drain passage 103. At this time, the water flow in the outlet passage 102 or downstream of the outlet passage 102 is siphoned to drain the drain valve (in the direction of the arrow in fig. 18) along the drain passage 103, so that the outlet device, such as a water nozzle of a shower, can drain the residual water in time without causing a problem of long-term residual water dripping. Meanwhile, as the second sealing element 320 is plugged in the water inlet channel 101, the residual water cannot flow back to the water supply pipeline from the water inlet channel 101, and the anti-siphon effect is achieved.
As shown in fig. 19, at the instant of water flowing, since the second sealing member 320 abuts against the inner wall surface of the second cavity 120, the water inlet end surface 211 and the inner wall surface of the second cavity 120 can form an energy storage cavity 122, and the energy storage cavity 122 can accumulate the water flow pressure entering the energy storage cavity. Since the pressure in the energy storage chamber 122 is close to the static pressure state, the valve core 200 can be driven to move even in a low water pressure state, so that the water inlet passage 101 can be quickly opened, and normal operation can be realized under extremely low water pressure.
Since the first sealing member 310 can slidably abut against the inner wall surface of the first chamber 110 to achieve sealing, when the valve cartridge 200 is moved from the initial position by the water flow pressure and the water inlet passage 101 is not completely opened, the first sealing member 310 has blocked the water discharge passage 103. Therefore, the drain passage 103 is closed before the water inlet passage 101 is completely opened, so that water leakage from the drain passage 103 under a low water pressure can be prevented.
As described above, the first sealing member 310 and the second sealing member 320 can be respectively abutted against the inner wall surface of the first cavity 110 and the inner wall surface of the second cavity 120, so that the water inlet passage 101 and the water discharge passage 103 are always in a non-communicated state, and water leakage of the water discharge passage 103 under low water pressure is prevented.
As shown in fig. 20, after the water is continuously supplied, the valve element 200 is moved toward the valve seat 100b against the elastic force of the elastic member 400 by the accumulated pressure to completely open the water inlet passage 101. Meanwhile, the first seal 310 slides along the inner wall surface of the first cavity 110, and always blocks the drainage passage 103.
In one embodiment, the second seal 320 may be a Y-ring seal. Because the Y-shaped sealing ring has the groove, when the second sealing element 320 is in slidable contact with the inner wall surface of the second cavity 120, the groove can make the Y-shaped sealing ring deform inward more easily, thereby reducing the friction between the second sealing element 320 and the inner wall surface of the second cavity 120, making the valve element 200 move more smoothly, and achieving the effect of normal use under low water pressure.
As shown in fig. 11 and 13, the drain valve further includes a flow regulator 700. The flow regulator 700 may be installed at the valve body 100a upstream of the water inlet passage 101. The drain valve according to the embodiment of the present invention can select an appropriate flow regulator 700 according to the flow rates of water flows in different regions. Besides the advantages of timely discharging residual water and preventing backflow, the drain valve of the embodiment of the invention has the function of flow control.
The invention also provides a water outlet device, which comprises the water discharge valve of any embodiment, so that the water outlet device of the embodiment of the invention has all the advantages and beneficial effects of any embodiment, and further description is omitted.
In one embodiment, the water outlet device may be a shower head.
In summary, the advantages and the benefits of the drain valve and the water outlet device of the embodiment of the invention are as follows:
since the first sealing member 310 has blocked the drain passage 103 when the valve cartridge 200 is moved from the initial position by the pressure of the water flow and the water inlet passage 101 is not completely opened. Therefore, the drain passage 103 is closed before the water inlet passage 101 is completely opened, so that the problem of water leakage from the drain passage 103 under a low water pressure can be avoided.
