As shown in fig. 1 to 4, the present disclosure provides a valve, which includes a valve body 1, a conduit assembly 2 and a blocking member 4, wherein the valve body 1 has a cavity 11 therein, an inlet 12 communicated with the cavity 11 is formed on the valve body 1, the conduit assembly 2 includes a first conduit 21 and a second conduit 22, the second conduit 22 is sleeved outside the first conduit 21, and a gap 23 is provided between the inner wall of the second conduit 22 and the outer wall of the first conduit 21, the conduit assembly 2 further comprises a first opening 31 and a second opening 32, the first opening 31 communicates the first conduit 21 with the cavity 11, the second opening 32 communicates the gap 23 with the cavity 11, so that the fluid medium can be discharged to the valve via the first conduit 21 and the gap 23, the closing member 4 comprises a first closing part 41 and a second closing part 42, the first closing part 41 closing or opening the first opening 31 and the second closing part 42 closing or opening the second opening 32.
In the above-described valve, the fluid medium can enter the cavity 11 of the valve body 1 through the inlet 12, and when the first opening 31 is opened by the first blocking portion 41, the fluid medium can enter the first conduit 21 through the first opening 31 and can be discharged to the valve through the first conduit 21. When the second blocking portion 42 opens the second opening 32, the liquid medium can enter the gap 23 between the outer wall of the first conduit 21 and the inner wall of the second conduit 22 through the second opening 32, so as to be able to be discharged to the valve through the gap 23. That is, the valve described above opens or closes the first opening 31 and the second opening 32 by the first blocking portion 41 and the second blocking portion 42, respectively, so that the fluid medium can be discharged from the valve through different conduits, and selection and switching of the flow path of the fluid medium are realized. Because the second guide pipe 22 is sleeved outside the first guide pipe 21, the first opening 31 and the second opening 32 can be arranged on the same side of the valve body 1, and the arrangement mode of mutual sleeving enables the structure arrangement of the first guide pipe 21 and the second guide pipe 22 to be tight, occupied space is small, the overall size of the valve body 1 is favorably reduced, and the arrangement of the valve body 1 is convenient.
The first conduit 21 and the second conduit 22 may be straight pipes or bent hoses, and the specific material and shape of the first conduit 21 and the second conduit 22 are not limited by the present disclosure. As shown in fig. 1, the first conduit 21 and the second conduit 22 may be arranged coaxially, so that the fluid medium can stably and uniformly pass through the gap 23 to be discharged to the valve.
The first blocking portion 41 is used for blocking or opening the first opening 31, and the second blocking portion 42 is used for blocking or opening the second opening 32, wherein the first blocking portion 41 and the second blocking portion 42 may be independent structures, that is, the position relationship between the first blocking portion 41 and the first opening 31 is independent from the position relationship between the second blocking portion 42 and the second opening 32, so as to achieve independent opening or closing of the first opening 31 and the second opening 32. In order to realize the switching function of the valve with respect to the flow path of the fluid medium, alternatively, the first blocking portion 41 and the second blocking portion 42 may be arranged in linkage, and the first blocking portion 41 and the second blocking portion 42 may be configured such that when the first blocking portion 41 is in a position to block the first opening 31, the second blocking portion 42 is in a position to open the second opening 32, and when the second blocking portion 42 is in a position to block the second opening 32, the first blocking portion 41 is in a position to open the first opening 31.
In the above-mentioned embodiment, the valve may have three modes, in the first mode, as shown in fig. 2, when the first blocking portion 41 is in the position of opening the first opening 31, the second blocking portion 42 is in the position of blocking the second opening 32, that is, the inlet 12 of the valve is communicated with the first conduit 21 and is blocked from the second conduit 22, the fluid medium cannot enter the second conduit 22, so as to avoid the second conduit 22 from shunting the fluid medium, and ensure that the fluid medium can completely flow out of the valve through the first conduit 21. In the second mode, as shown in fig. 3, when the first blocking portion 41 is in the position for blocking the first opening 31, the second blocking portion 42 is in the position for opening the second opening 32, the inlet 12 of the valve is communicated with the second conduit 22 and is blocked from the first conduit 21, and the fluid medium cannot enter the first conduit 21, so that the fluid medium is prevented from being shunted by the first conduit 21, and the fluid medium can be ensured to completely flow out of the valve through the second conduit 22.
In the third mode, the first blocking portion 41 may be in a position at least partially opening the first opening 31 and the second blocking portion 42 is in a position at least partially opening the second opening 32, i.e. the inlet 12 of the valve may be in communication with the first conduit 21 and the second conduit 22, respectively, and the fluid medium may flow out of the valve through the first conduit 21 and the gap 23, respectively.
Alternatively, the valve may comprise a driver 5 and a link 6, the driver 5 being configured to drive the first blocking portion 41 and the second blocking portion 42 to move via the link 6 to open or close the first opening 31 and open or close the second opening 32, respectively.
Wherein, as shown in fig. 1, the link 6 comprises a main link 60, a first link 61 and a second link 62, the first link 61 is connected between the main link 60 and the first blocking portion 41, the second link 62 is connected between the main link 60 and the second blocking portion 42, and the driving member 5 is used for driving the main link 60 to move in a direction approaching to or moving away from the first guide duct 21 and the second guide duct 22. In this embodiment, the connecting rod 6 is adopted to realize transmission of the driving force, the driving member 5 only needs to drive the main connecting rod 60 to move in a direction close to or far away from the first conduit 21 and the second conduit 22, and the main connecting rod 60 can respectively drive the first connecting rod 61 and the second connecting rod 62 to move, so as to drive the first plugging portion 41 and the second plugging portion 42 to realize position change.
In the above embodiment, when the driving member 5 drives the main link 60 to move in the direction approaching to the first conduit 21, the main link 60 drives the first link 61 to drive the first blocking portion 41 to approach to the first opening 31 or move away from the first opening 31, which is related to the relative position relationship between the first blocking member 4 and the first opening 31. As an exemplary embodiment, as shown in fig. 1, an end plate 211 may be disposed in the first conduit 21, the end plate 211 has a first opening 31 formed thereon, the first link 61 is disposed through the first opening 31, the first blocking portion 41 is disposed in the first conduit 21 and located on a side of the end plate 211 away from the cavity 11, and a projection of the first blocking portion 41 on the end plate 211 covers the first opening 31.
As shown in fig. 2 and 3, since the first blocking portion 41 is provided in the first conduit pipe 21 on the side of the end plate 211 away from the cavity 11, when the main link 60 is close to the first conduit pipe 21 and the second conduit pipe 22, the first blocking portion 41 is away from the end plate 211, so that a gap is created between the first blocking portion 41 and the end plate 211, and the fluid medium in the cavity 11 can flow into the first conduit pipe 21 through the first opening 31 in the end plate 211 and the gap between the first blocking portion 41 and the end plate 211, so that the valve body 1 can be discharged through the first conduit pipe 21. That is, in this embodiment, when the driving member 5 drives the main link 60 to move in a direction approaching the first conduit 21, the main link 60 drives the first link 61, and the first blocking portion 41 can be driven away from the first opening 31, so as to open the first opening 31.
In order to ensure that the first blocking portion 41 can perform a good blocking function on the first opening 31, optionally, an elastic member 212 may be further disposed in the first conduit 21, and the elastic member 212 is used for providing an elastic force for pressing the first blocking portion 41 against the end plate 211. As shown in fig. 3, when the driving element 5 drives the main link 60 to move away from the first conduit 21 and the second conduit 22, the first blocking portion 41 abuts against the side portion of the end plate 211, the first blocking portion 41 can completely block the first opening 31, and the elastic force of the elastic element 212 can press the first blocking portion 41 against the end plate 211, so that the first opening 31 can be prevented from being opened due to the separation of the first blocking portion 41 and the end plate 211 caused by the water pressure in the cavity 11, thereby ensuring that the first blocking portion 41 can stably block the first opening 31.
The elastic member 212 may be an elastic block, an elastic sheet, a spring structure, or the like, alternatively, the elastic member 212 may be a spring, and the spring is sleeved outside the first connecting rod 61, wherein one end of the spring may be connected to the first blocking portion 41, and the other end of the spring is connected to the inner wall of the first conduit 21, or one end of the spring may be connected to the first connecting rod 61, and the other end of the spring is connected to the end plate 211. In the above embodiment, one end of the spring is connected to the first blocking portion 41 or the first link 61, and the spring is deformed during the movement of the first blocking portion 41 or the first link 61, so as to generate an elastic force. The other end of the spring is connected to the inner wall or the end plate 211 of the first conduit 21 and can be kept fixed without moving, so that the spring is deformed correspondingly when the first blocking portion 41 or the first link 61 moves, and an elastic force is applied to the first blocking portion 41.
As a first exemplary embodiment, as shown in fig. 1 to fig. 3, one end of the spring may be connected to the first link 61, and the other end of the spring may be connected to the end plate 211, when the first link 61 moves toward a direction close to the end plate 211, the spring is compressed and deformed to generate an elastic force, and when the driving force applied to the first link 61 is removed, the first link 61 moves toward a direction away from the end plate 211 under the action of the spring, so as to bring the first blocking portion 41 into contact with the end plate 211. In order to ensure that the spring still provides the elastic force in the state that the first blocking portion 41 and the end plate 211 are attached, optionally, the spring may be in a compressed state all the time.
As a second exemplary embodiment, as shown in fig. 4, one end of the spring may be connected to the first blocking portion 41, and the other end may be connected to the inner wall of the first conduit 21, and when the first blocking portion 41 moves toward the end plate 211, the spring is subjected to tensile deformation, and when the driving force applied to the first blocking portion 41 is removed, the first blocking portion 41 moves toward the end plate 211 by the spring, and is attached to the end plate 211. In order to ensure that the spring still provides an elastic force in the state where the first blocking portion 41 and the end plate 211 are attached, the spring may alternatively be in a stretched state all the time.
The second guide tube 22 is sleeved outside the first guide tube 21, optionally, the gap 23 is used for communicating with the open end of the cavity 11, i.e., the second opening 32, the second blocking portion 42 is used for blocking or opening the second opening 32, the second blocking portion 42 may be located in the cavity 11, and when the driving member 5 drives the main link 60 to approach the first guide tube 21 and the second guide tube 22, the second blocking portion 42 approaches the second opening 32.
In order to ensure that the second blocking portion 42 can be stably close to or far from the second opening 32, as shown in fig. 1, optionally, the end of the first conduit 21 close to the cavity 11 may protrude out of the end of the second conduit 22 close to the cavity 11 to form a protruding section 213, and the second blocking portion 42 may be formed as an annular sealing structure which is movably sleeved on the outer wall of the protruding section 213. In this embodiment, when the driving member 5 drives the main link 60 to approach the second guiding tube 22, the second link 62 drives the second blocking portion 42 to approach the second opening 32, and since the second blocking portion 42 can be formed as an annular sealing structure and movably sleeved on the outer wall of the protruding section 213, the outer wall of the protruding section 213 can guide the movement of the annular sealing structure, and the second blocking portion 42 is prevented from deflecting or skewing. Under the state that the second blocking portion 42 blocks the second opening 32, the outer wall of the protruding section 213 can keep close to the second blocking portion 42, so that the fluid medium is prevented from entering the second conduit 22 through the gap 23 between the second blocking portion 42 and the outer wall of the first conduit 21, and the second blocking portion 42 can play a good blocking effect.
