Description

Technical Field

[0001] The present invention relates to the technical field of pipeline valves, and in particular to a pipeline valve for closing and / or switching. Background Art

[0002] When it is necessary to switch between two outlets in the case of a water pipe heating element, problems often occur, for example, between the outlet leading to the bathtub and the outlet leading to the hand-held shower head. The switching switch between the two outlets can be provided in the hand-held shower head. It is known that the pipe fitting has a valve actuated by a control rod or a switching button. It is known that the control rod can swing, and the button can be pressed, pulled or rotated.

[0003] However, when the propulsion device in the valve is urged by the control rod to move the valve from one stable, discontinuous position to another stable, discontinuous position, a large force is required, resulting in difficult operation. Summary of the Invention

[0025] In some embodiments, when the plugging assembly only plugs the first water passage hole, the fluid entering the water inlet cavity from the inlet flows into the second water outlet cavity through the gap between the water stop member and the lower valve body and flows out from the second outlet. At this time, since the fluid flows into the water containing cavity from the overflow hole on the water stop member, there is a pressure difference between the first water outlet cavity and the water containing cavity, thereby sealing the water stop member and the water stop rib corresponding to the first water outlet cavity on the lower valve body; or

[0026] When the plugging assembly only plugs the second water passage hole, the fluid entering the water inlet cavity from the inlet flows into the first water outlet cavity through the gap between the water stop member and the lower valve body and flows out from the first outlet. At this time, since the fluid flows into the water containing cavity from the overflow hole on the water stop member, there is a pressure difference between the second water outlet cavity and the water containing cavity, thereby sealing the water stop member and the water stop rib corresponding to the second water outlet cavity on the lower valve body.

[0027] In some embodiments, each of the lower valve body, the water stop member and the upper valve body is provided with a guide groove at the center.

[0028] In some embodiments, the switching assembly includes a switching shaft, a first spring, the rotating disk, a guide shaft, a second spring and a button,

[0029] The button is received in the receiving groove on the lower valve body;

[0030] One end of the switching shaft passes through the guide groove of the lower valve body and is connected to the button, and the other end of the switching shaft with the switching shaft helical teeth is located in the guide groove of the lower valve body to allow the switching shaft to move along the guide groove of the lower valve body;

[0031] The lower valve body helical teeth are arranged in the guide groove of the lower valve body, and the lower valve body helical teeth cooperate with the switching shaft rib of the switching shaft. The switching shaft helical teeth are located on the switching shaft rib of the switching shaft;

The other end of the guide shaft passes through the central hole of the rotating disk and the second spring located above the rotating disk and is then installed on the shaft seat at the top of the upper cover body.

[0034] In some embodiments, when the button is pressed, the button pushes the switching shaft to move upward, and the switching shaft pushes the rotating disk to move upward. After the rib of the rotating disk leaves the guiding groove of the lower valve body, the engagement between the helical teeth of the switching shaft and the helical teeth of the rotating disk causes the rotating disk to rotate a first predetermined angle;

[0035] After that, when the button is released, under the elastic force of the first spring, the switching shaft and the button reset to the original state. Under the elastic force of the second spring, the helical teeth of the rotating disk cooperate with the helical teeth of the lower valve body and drive the rotating disk to rotate a second predetermined angle.

[0050] Although this disclosure allows various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will be described in detail herein. However, it should be understood that the accompanying drawings and the detailed description are not intended to limit this disclosure to the specific forms disclosed, but on the contrary, are intended to cover all modifications, equivalent forms, and alternative forms that fall within the spirit and scope of this disclosure as defined by the appended claims. The drawings are for illustration purposes and thus are not drawn to scale.

[0051] In this specification, terms such as "first" and "second" are not used for ranking or indicating importance or primary-secondary relationship, but are used to distinguish different components.

[0052] As Figure 1As shown, the pipeline valve for closing and / or switching according to an embodiment of the present invention includes a valve body, an inlet, an outlet, a water stop member, a plugging assembly, a switching assembly, etc. In this example, the valve body includes an upper cover body 21, an upper valve body 215, and a lower valve body 25 that cooperate with each other. In one example, the upper valve body 215 and the lower valve body 25 are connected by fixing members, such as bolts 214.

[0053] See Figure 2 and Figure 3 , the right end of the lower valve body 25 is provided as an inlet 251. Correspondingly, a first outlet 252 and a second outlet 253 are sequentially provided at the left end of the lower valve body 25, and the first outlet 252 and the second outlet 253 are respectively communicated with the water-containing cavity of the valve body (to be described in detail below). It should be noted that in this example, one inlet and two outlets are used as an example to illustrate the design concept of the present invention, but it can be understood that those skilled in the art can set their quantities according to actual needs, rather than being limited to the example shown here.

[0054] Combined with Figures 1 - 3 shown, corresponding to the first outlet 252 and the second outlet 253, a first water outlet cavity 254 and a second water outlet cavity 255 are provided in the middle part of the lower valve body 25, and a water inlet cavity 256 is provided in the peripheral part of the lower valve body. The first water outlet cavity 254 and the second water outlet cavity 255 are closed by a water stop member 26 and a plugging assembly that cooperate with each other. The inlet 251 is sequentially communicated with the water inlet cavity 256 of the lower valve body 25 and the water-containing cavity of the valve body (to be described in detail below), and the communication or disconnection with the first water outlet cavity 254 and the second water outlet cavity 255 is realized via the water stop member 26.

[0055] Above the water stop member 26, an upper valve body 215 and an upper cover body 21 are sequentially provided. The space between the upper valve body 215 and the water stop member 26 is a water-containing cavity 261. The water-containing cavity 261 is also sealed via the upper valve body 215, the plugging assembly, and the water stop member 26, that is, the water stop member 26 is sealed by the upper valve body 215 and the plugging assembly (for example, from the upper part) to seal the water-containing cavity 261, so as to realize the communication or disconnection between the water stop member 26 and the first water outlet cavity 254 and the second water outlet cavity 255, and the communication or disconnection with the water inlet cavity 256.

[0056] Actually, the purpose of setting the water stop member 26 in the cavity of the valve body is mainly to prevent the direct communication between the inlet 251 and the first outlet 252 and the second outlet 253, so that the selective communication between them can be realized through the switching assembly described later.

[0057] The switching component is configured such that by its rotation, the plugging component plugs the corresponding water passing holes 262, 263 on the water stop member 26, so as to be able to close the communication between the inlet 251 and the first outlet 252 and the second outlet 253 and / or switch between the first outlet 252 and the second outlet 253.

[0058] To achieve the closing of the first outlet 252 and the second outlet 253 or the switching between them, the water passing holes on the water stop member 26 include a first water passing hole 262 that communicates with the first water outlet cavity 254 when assembled into the valve body and a second water passing hole 263 that communicates with the second water outlet cavity 255. It can be understood that the number of water passing holes on the water stop member 26 is usually set to correspond to the number of water outlet cavities, and the size of the water passing holes can be selected according to actual needs.

[0059] In addition, specifically referring to Figure 8 , in addition to the first water passing hole 262 and the second water passing hole 263, the water stop member 26 is also provided with at least one overflow hole 264 (as shown in the figure, two overflow holes 264 are shown) to achieve the communication between the water inlet cavity 256 and the water containing cavity 261.

[0060] In one example, the water stop member 26 is a water stop pad made of an elastic material and includes a body and a first water stop flange portion 265 and a second water stop flange portion 266 provided on the body. The first water stop flange portion 265 is correspondingly arranged with the first water outlet cavity 254 and the second water stop flange portion 266 is correspondingly arranged with the second water outlet cavity 255. And the first water passing hole 262 is located in the area surrounded by the first water stop flange 265 portion, and the second water passing hole 263 is located in the area surrounded by the second water stop flange portion 266. As Figure 1 and Figure 8 shown, at least a part of the first water stop flange portion 265 and the second water stop flange portion 266 is received in the water stop rib 257 of the lower valve body 25 (see Figure 3 ), so as to realize that when the water stop member 26 is pushed upward by a relatively large water pressure from the water outlet cavities 254, 255, the corresponding first water stop flange portion 265 and / or the second water stop flange portion 266. At the same time, when the first water stop flange portion 265 and / or the second water stop flange portion 266 cooperate with the water stop rib 257 on the lower valve body 25, the corresponding first water outlet cavity 254 and / or the second water outlet cavity 255 can be sealed.

[0061] It should be noted that the sizes of the first water stop flange portion and the second water stop flange portion, as well as the number and sizes of the first receiving hole, the second receiving hole, etc. can be selected according to actual needs.

[0062] In addition, it should be noted that referring to Figure 8, mounting and positioning holes (not labeled) may also be provided in the region of the body outside the region surrounded by the first water stop flange portion 265 and the second water stop flange portion 266 to facilitate mounting and positioning, which will not be elaborated here in detail.

[0063] As Figure 1 shown, the switching assembly includes the switching shaft 212, the first spring 211, the rotating disk 24, the guide shaft 22, the second spring 23, the third spring 213, and the button 216. As Figure 3 shown, a first receiving hole 215a and a second receiving hole 215b for receiving the corresponding plugging assembly are provided on the upper valve body 215, and the first receiving hole 215a corresponds to the first water passing hole 262 on the water stop member 26, and the second receiving hole 215b corresponds to the second water passing hole 263 on the water stop member 26, and they are arranged corresponding to each other. The space corresponding to the first receiving hole 215a and the second receiving hole 215b between the upper valve body 215 and the water stop member 26 is the water receiving cavity.

[0064] It should be noted that the number, shape, and size of the receiving holes can be designed according to needs. Preferably, the number, shape, and size of the receiving holes are the same as those of the water passing holes on the water stop member.

[0065] To install the switching assembly in the valve body, each of the upper valve body 215, the lower valve body 25, and the water stop member 26 is provided with a guide groove at the center (as Figure 3 shown, each of them is provided with a guide groove. For the reason of simplicity of illustration, only the corresponding guide grooves 258 and 267 are shown on the lower valve body 25 and the water stop member 26 respectively (see Figure 8 ).

[0066] The button 216 is received in a receiving groove (not shown) on the lower valve body 25; one end of the switching shaft 212 passes through the guide groove 258 of the lower valve body 25 (see Figure 3 ) and is inserted into the third spring 213 (it should be noted that the third spring 213 can be omitted without affecting the operation of the button 216) and then connected to the button, and the other end of the switching shaft 212 with the switching shaft helical teeth 212a (as Figure 7A shown) is located in the guide groove 258 of the lower valve body to allow the switching shaft 212 to move along the guide groove 258 of the lower valve body.

[0067] See Figure 7B and Figure 7C, a lower valve body helical tooth 258a is arranged in a guide groove 258 of the lower valve body, the lower valve body helical tooth 258a cooperates with a switching shaft rib 212b, and a switching shaft helical tooth 212a is located on the switching shaft rib 212b on the switching shaft 212.

[0068] See Figure 3 and Figure 9 , a rotating disk rib 241 and a rotating disk helical tooth 242 located on the rotating disk rib are provided on the rotating disk 24, the rotating disk rib 241 is located in guide grooves of an upper valve body 215 and a lower valve body 25 and moves along the guide grooves of the upper valve body 215 and the lower valve body 25, wherein one end of the guide groove 258 of the lower valve body, which faces away from the button 216, is inserted into the guide groove of the upper valve body 215.

[0069] As Figure 1 and 3 shown, a first spring 211 is arranged at one end of the guide shaft 22 and is accommodated in an inner cavity of the switching shaft 212, and the other end of the guide shaft 22 passes through a central hole 243 of the rotating disk 24 (see Figure 9 ) and a second spring 23 located above the rotating disk and is then mounted on a shaft seat 201 at the top of the upper cover body 21.

[0070] When the button 216 is pressed, the button 216 pushes the switching shaft 212 to move upward, the switching shaft 212 pushes the rotating disk 24 to move upward, and after the rotating disk rib 241 leaves the guide groove 258 of the lower valve body 25, the cooperation between the switching shaft helical tooth 212a and the rotating disk helical tooth 242 causes the rotating disk to rotate a first predetermined angle (for example, 90°).

[0071] After that, when the button 216 is released, under the elastic force of the first spring 211, the switching shaft 212 and the button 216 are reset to the original state, the rotating disk helical tooth 242 cooperates with the lower valve body helical tooth 258a, and under the elastic force of the second spring 23, the rotating disk 24 is driven to rotate a second predetermined angle (for example, 90°), the rotating disk rib 241 slides into the guide groove 258 of the lower valve body, and moves along the guide groove 258 of the lower valve body until a switching hole of the rotating disk (to be described in detail below) selectively accommodates a plugging component (to be described in detail below) in the first accommodation hole 215a and the second accommodation hole 215b.

[0072] As described above, the rotating disk 24 is located above the upper valve body 215. Three switching holes 244 are provided on the rotating disk 24. The three switching holes are located on the same circumference centered on the central hole 243 of the rotating disk, adjacent to each other and spaced 90° apart. The three switching holes 244 selectively release or block a blocking component (to be described below) in either the first receiving hole 215a or the second receiving hole 215b according to the rotation of the rotating disk.

[0073] In this example, three switching holes are taken as an example to illustrate the design concept of the present invention. However, it can be understood that those skilled in the art can set their number according to actual needs. For example, the switching holes can be designed as 1, 2 (as Figure 9 shown), and are not limited to the examples here.

[0074] Combined with Figures 1 - 3 shown, blocking components are provided in both the first receiving hole 215a and the second receiving hole 215b of the upper valve body 215. The structure and function of the blocking component in the first receiving hole 215a are the same as those of the second receiving hole 215b. The structure and function of the first receiving hole 215a are the same as those of the second receiving hole 215b. Therefore, only the first receiving hole 215a and the blocking component therein are taken as an example here, and the second receiving hole 215b and the blocking component therein will not be described in detail here.

[0075] It should be noted that the number, shape, and size of the blocking component correspond to the number, shape, and size of the receiving holes of the upper valve body, as long as it can be realized that the blocking component can move up and down in the receiving hole while sealing the receiving hole.

[0076] The blocking component includes a sealing shaft 29 passing through the first receiving hole 215a, a sealing body 210 at the first end of the sealing shaft 29, a sealing ring 28 at the second end of the sealing shaft 29, and a spring 27 located on the sealing shaft 29. The first end and the second end of the sealing shaft 29 are opposite ends of the sealing shaft 29.

[0077] An annular protrusion 215c is provided in the first receiving hole 215a of the upper valve body 215. A protrusion 291 is provided at one end of the sealing shaft 29 connected to the sealing body 210. The protrusion 291 protrudes outward below the protrusion 215c to at least partially abut against the protrusion 215c. The sealing ring 28 and the spring 27 are sequentially provided on the side of the protrusion 215c facing away from the protrusion 291.

[0078] A groove is provided at the center of the first end of the sealed shaft 29, and a protrusion 210a is provided in the middle part of the seal body 210, such that the cross-section of the seal body 210 is generally in the shape of a "mountain". The protrusion 210a is received in the groove, and the peripheral part of the seal body 210 surrounds the protrusion 291 and is flush with the surface of the protrusion 291, that is, the surface of the protrusion 291 on the side close to the protrusion 215c is flush with the protrusions on both sides of the "mountain"-shaped seal body 210.

[0079] It should be noted that the sealed shaft 29 and the seal body 210 can be two mutually independent components, such as Figure 10A shown, and of course they can also be an integrally formed part, such as Figure 10B shown. Those skilled in the art can make corresponding selections according to needs.

[0080] A stepped hole is provided at the center of the sealing ring 28, and a stepped convex head 292 is provided at the second end of the sealed shaft. The convex head 292 is fitted into the hole of the sealing ring 28. Those skilled in the art should understand that the hole of the sealing ring 28 can also be provided with a stepped hole having 2 or 3 steps. Correspondingly, the convex head at the second end of the sealed shaft is also provided with 2 or 3 steps. Those skilled in the art can make corresponding selections according to needs.

[0081] When the plugging assembly only plugs the first water passage hole 262, the fluid entering the water inlet cavity 256 from the inlet 251 flows into the second water outlet cavity 255 through the gap between the water stop member 26 and the lower valve body 25 and cannot flow into the first water outlet cavity 254. Therefore, the fluid can only flow out from the second outlet 253. At this time, since the fluid flows into the water containing cavity 261 from the overflow hole 264 on the water stop member, there is a pressure difference between the first water outlet cavity 254 and the water containing cavity 261, thereby sealing the water stop rib 257 on the water stop member 26 and the lower valve body 25 corresponding to the first water outlet cavity 254.

[0082] Of course, when the plugging assembly only plugs the second water passage hole 263, the fluid entering the water inlet cavity 256 from the inlet 251 flows into the first water outlet cavity 254 through the gap between the water stop member 26 and the lower valve body 25 and cannot flow into the second water outlet cavity 25. Therefore, it can only flow out from the first outlet 252. At this time, since the fluid flows into the water containing cavity 261 from the overflow hole 264 on the water stop member 26, there is a pressure difference between the second water outlet cavity 255 and the water containing cavity 261, thereby sealing the water stop rib 257 on the water stop member 26 and the lower valve body 25 corresponding to the second water outlet cavity 255.

[0083] It should be noted that in the present invention, water is taken as an example of the fluid to illustrate the working principle of the pipeline valve of the present invention. Of course, the pipeline valve of the present invention can also be used for other types of fluids.

[0084] The following will combine with the Figures 2 - 5 The switching principle of the present invention will be described in combination with different states of the pipeline valve.

[0085] State one is called the initial state, that is, the state where only the first outlet 252 discharges water; state two is the state where after the button 216 is pressed once, both the first outlet 252 and the second outlet 253 discharge water; state three is the state where after the button 216 is pressed again (the button 216 is pressed twice relative to the initial state), only the second outlet 253 discharges water; state four is the state where after the button is pressed again (the button 216 is pressed three times relative to the initial state), both the first outlet 252 and the second outlet 253 discharge water.

[0086] Specifically, referring to Figure 3 , the plugging component in the first receiving hole 215a is received in the switching hole 244 of the rotating disk 24, so that the plugging component leaves the first water passing hole 262, and thus the first water passing hole 262 is not blocked by the plugging component. After water enters the water inlet cavity 256, it flushes open the first water stop flange portion 265 and enters the first water outlet cavity 254, thereby causing water to discharge from the first outlet 252.

[0087] Since the plugging component in the second receiving hole 215b is blocked by the main body of the rotating disk 24, the plugging component blocks the second water passing hole 263, and the second water stop flange portion 266 contacts the water stop rib 257 on the lower valve body 25. Water enters the water receiving cavity 261 through the overflow hole 264 on the water stop member 26 located outside the first water stop flange portion 265 and the second water stop flange portion 266. At this time, the water receiving area on the upper surface of the second water stop flange portion 266 is larger than the water receiving area on the lower surface, thereby generating a water pressure difference. Under the action of this water pressure difference, the second water stop flange portion 266 is tightly sealed with the water stop rib 257 of the lower valve body 25, resulting in that water cannot enter the second water outlet cavity 255, so the second outlet 253 does not discharge water.

[0088] As Figure 3 shown in the top view on the upper right in, the rotating disk 24 is located at the lower position in the page, and the switching hole on it just receives the plugging component in the first receiving hole 215a.

[0089] Combined with Figure 1 , 2 and Figure 3 , the switching shaft rib 212b is placed in the guiding groove 258 of the lower valve body and moves along the guiding groove 258 of the lower valve body.

[0090] The switching shaft helical gear 212a mates with the rotating disk helical gear 242. The rotating disk rib 241 is placed in the guiding groove 258 of the lower valve body and moves along the guiding groove 258 of the lower valve body.

[0091] See Figure 4 , after pressing the lower button 216, the button 216 pushes the switching shaft 212 to move vertically upward. The switching shaft 212 pushes the rotating disk 24 to move vertically upward. When the rotating disk rib 241 leaves the guiding groove 258 of the lower valve body, the mating of the switching shaft helical gear 212a and the rotating disk helical gear 242 will drive the rotating disk 24 to rotate a certain angle (for example, 90°). At this time, in the corresponding top view page, the rotating disk 24 is rotated 90° to the left relative to the Figure 3 position shown.

[0092] See Figure 4 , after releasing the button 216, under the elastic force of the first spring 211, the switching shaft 212 and the button 216 reset to the original state. The rotating disk helical gear 242 mates with the lower valve body helical gear 258a. Under the elastic force of the second spring 23, it will drive the rotating disk 24 to rotate a certain angle (for example, 90°). The rotating disk rib 241 slides into the guiding groove 258 of the lower valve body and moves along the guiding groove 258 until the two in the switching holes 244 on the rotating disk 24 respectively accommodate the plugging components in the first accommodating hole 215a and the second accommodating hole 215b on the water stop member 26 (that is, the switching holes 244 on the rotating disk 24 are rotated 90° to the left relative to the Figure 3 position shown).

[0093] At this time, the first water passing hole 262 is not blocked. After water enters the water inlet cavity 256, the water flushes open the first water stop flange portion 265 and enters the first water outlet cavity 254, resulting in water flowing out from the first outlet 252. Similarly, the second water passing hole 263 is not blocked. After water enters the water inlet cavity 256, the water flushes open the second water stop flange portion 266 and enters the second water outlet cavity 255, resulting in water flowing out from the second outlet 253 as well.

[0094] See Figure 5 , pressing the button 216 again (the second time pressing the button 216), which causes the switching holes 244 on the rotating disk 24 (combined with the Figure 9 position shown) to rotate 90° again, so that the switching holes 244 exactly accommodate the plugging components in the second accommodating hole 215b, making the second water passing hole 263 not blocked. Similar to the initial state, at this time, it will cause water to pass through the second water outlet cavity 255 and make the second outlet 253 discharge water, while the first outlet 252 does not discharge water.

[0095] See Figure 6Press the button 216 again (the third time to press the button 216), which causes the switching hole 244 on the rotating disk 24 to rotate 90° again, so that the plugging components in the first receiving hole 215a and the second receiving hole 215b on the water stop member 26 are respectively received in the two relatively arranged switching holes 244 exactly.

[0096] Similar to State 2, at this time, since the switching hole 244 does not block the first water passing hole 262 and the second water passing hole 263, both the first outlet 252 and the second outlet 253 discharge water.

[0097] It should be noted that in the embodiment of the present invention, a first water stop flange portion is provided on the water stop pad corresponding to the first water outlet cavity, and a second water stop flange portion is provided on the portion corresponding to the second water outlet cavity. The first water passing hole is located in the area surrounded by the first water stop flange portion, and the second water passing hole is located in the area surrounded by the second water stop flange portion. However, it can also be set as required to have water receiving holes or a plurality of protruding portions at other angles to achieve that in a certain state, neither the first outlet nor the second outlet discharges water. In view of these contents, they can all be obtained based on the disclosure of the present invention without any creative labor, so they will not be elaborated in detail here.

[0098] Specifically, in combination with Figure 9 As shown, the left figure shows that three adjacent receiving holes are provided on the rotating disk 24, which are located on the substantially same circumference of the rotating disk 24 and are spaced at an angle of about 90 degrees from each other. Through the rotation of the rotating disk 24 and the cooperation with the plugging component, single outlet water discharge, two-outlet mixed water discharge, single outlet water discharge of the other of the two outlets, and two-outlet mixed water discharge of the two outlets of the pipeline valve can be achieved, as described above.

[0099] In one example, when the pipeline valve is used for a shower head, one of the outlets can be set to massage water, and the other outlet can be set to shower water, and the mixed water discharge is the case where the shower water and the massage water flow out simultaneously.

[0100] Figure 9 The middle view in shows another alternative example of the present invention. Two adjacent receiving holes can also be provided on the rotating disk 24, which are located on the substantially same circumference of the rotating disk 24 and are spaced at an angle of about 90 degrees from each other. Through the rotation of the rotating disk 24 and the cooperation with the plugging component, it is possible to always have only one of the outlets discharging water without mixed water flowing out.

[0101] Figure 9The right view in [ID] shows another alternative example of the present invention. One receiving hole can also be provided on the rotating disk 24, which is located on the circumference of the rotating disk 24. Through the rotation of the rotating disk 24 and its cooperation with the plugging assembly, the following sequential water flow can be achieved: water flows out from one of the two water outlets; water does not flow out from both water outlets; water flows out from the other water outlet of the two water outlets; water does not flow out from both water outlets. Through the above examples, it can be seen that the number of receiving holes on the rotating disk 24 can be set as required to adjust the water output of the two outlets.

[0102] For the pipeline valve for closing and / switching according to the present invention, through the cooperation of the switching assembly and the water stop member, the switching of the water output state between the first outlet and / or the second outlet can be achieved by applying a small force.
