Description

Technical Field

[0001] The utility model relates to the field of multi-channel valves, and particularly relates to a multi-channel valve capable of separately controlling each sealing structure. Background Art

[0002] The multi-channel valve is used to divert the liquid in the main pipeline to the branch pipelines so as to control the liquid flow rate of the branch pipelines. Chinese Patent CN202222368185.4 discloses a multi-channel integrated control valve, which includes a valve body, a multi-channel flow passage formed in the valve body, a plurality of connection ends formed in the valve body and communicated with the multi-channel flow passage, and a plurality of control valve cores installed on the valve body. An installation port for separately installing each control valve core is formed on the valve body. The plurality of installation ports and the plurality of connection ends are arranged in a circumferential distribution around the outer periphery of the valve body, and the plurality of installation ports and the plurality of connection ends are located in the same plane. The plurality of installation ports are located on the same side of the valve body. The utility model has the following advantages and effects: The structure of the utility model is simple and the required installation space is small, so it has better versatility and practicability.

[0003] The existing multi-channel valves have the following problems: It is necessary to operate the handwheel correspondingly installed on the control valve core to realize the on-off of the branch pipeline, and the control process is cumbersome.

[0004] Based on the above situation, there is an urgent need for a multi-channel valve capable of separately controlling each sealing structure to solve the problem of cumbersome control process. Summary of the Utility Model

[0005] The purpose of the utility model is as follows: Aiming at the existing multi-channel valves, it is necessary to operate the handwheel correspondingly installed on the control valve core to realize the on-off of the branch pipeline, and the control process is cumbersome. Therefore, a multi-channel valve capable of separately controlling each sealing structure is provided to solve the problem of cumbersome control process.

[0006] The technical solution of the utility model is as follows:

[0007] A multi-channel valve capable of separately controlling each sealing structure includes:

[0008] A liquid inlet pipe, connected to the main pipeline;

[0009] A plurality of liquid outlet pipes, communicated with the liquid inlet pipe and connected to the corresponding branch pipelines;

[0010] A sealing structure, arranged on the liquid outlet pipe and used for sealing the corresponding liquid outlet pipe;

[0011] A controller, used to separately control each of the sealing structures.

[0012] The existing multi-channel valves have complex structures and are not convenient for individually controlling the on / off of branch pipelines. In this solution, each sealing structure is individually controlled by the controller. Compared with traditional multi-channel valves, it avoids operating the handwheels correspondingly installed on the valve cores one by one, simplifies the control process, and solves the problem of cumbersome control process.

[0013] Furthermore, the specific structure of the sealing structure is not uniquely defined in this solution. One feasible solution is that the sealing structure includes a valve core and an elastic seal installed on the valve core. When this solution is adopted, the on / off of the corresponding liquid outlet pipe is achieved by adjusting the position of the seal.

[0014] Furthermore, in order to facilitate the reset of the elastic seal, one feasible solution is that the valve core is connected with a reset member and the reset member is used to push the elastic seal towards the liquid outlet pipe. When this solution is adopted, the elastic seal is pushed towards the liquid outlet pipe by the reset member to achieve the reset of the elastic seal and block the liquid outlet pipe.

[0015] Furthermore, the driving method of the elastic seal is not uniquely defined in this solution. One feasible solution is that a traction assembly for pulling the valve core is installed on the sealing structure. When this solution is adopted, the valve core is pulled by the traction assembly, and then the elastic seal is separated from the inner wall of the liquid outlet pipe to facilitate the flow of liquid from the liquid outlet pipe.

[0016] Furthermore, the specific structure of the traction assembly is not uniquely defined in this solution. One feasible solution is that the traction assembly includes a coil and an iron core arranged inside the coil, and the coil is electrically connected to the controller. When this solution is adopted, direct contact between the traction assembly and the valve core can be avoided, improving the sealing performance and service life.

[0017] Furthermore, in order to facilitate the replacement of the sealing structure, one feasible solution is that the sealing structure is detachably installed on the liquid outlet pipe. When this solution is adopted, it is convenient to disassemble and replace the sealing structure.

[0018] The beneficial effects of the present utility model compared with the existing technology are as follows:

[0019] First, each sealing structure is individually controlled by the controller. Compared with traditional multi-channel valves, it avoids operating the handwheels correspondingly installed on the valve cores one by one, simplifies the control process, and solves the problem of cumbersome control process;

[0020] Second, since the valve core is connected with a reset member and the reset member is used to push the elastic seal towards the liquid outlet pipe, the elastic seal is pushed towards the liquid outlet pipe by the reset member to achieve the reset of the elastic seal and block the liquid outlet pipe;

[0021] 3. Since the traction component includes a coil and an iron core disposed within the coil, and the coil is electrically connected to the controller, it is possible to avoid direct contact between the traction component and the valve core, thereby improving the sealing performance and service life.

[0031] It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0032] The features and performance of the present invention will be further described in detail below in conjunction with the embodiments.

[0033] Embodiment:

[0034] Please refer toFigure 1 , a multi-channel valve capable of individually controlling each sealing structure, comprising:

[0035] A liquid inlet pipe 1, connected to the main pipeline 2;

[0036] A plurality of liquid outlet pipes 3, communicating with the liquid inlet pipe 1 and connected to the corresponding branch pipelines 4;

[0037] A sealing structure 5, arranged on the liquid outlet pipe 3 and used to seal the corresponding liquid outlet pipe 3;

[0038] A controller, used to individually control each sealing structure 5.

[0039] For the existing multi-channel valve, the structure is complex and it is not convenient to individually control the on-off of the branch pipelines. In this solution, each sealing structure 5 is individually controlled by the controller. Compared with the traditional multi-channel valve, it avoids operating the handwheels correspondingly installed on the control valve cores one by one, simplifies the control process, and solves the problem of cumbersome control process.

[0040] Refer to Figure 2 and Figure 3 , this solution does not uniquely define the specific structure of the sealing structure 5. One feasible solution is: the sealing structure 5 includes a valve core 51 and an elastic sealing member 52 installed on the valve core 51. When this solution is adopted, by adjusting the position of the elastic sealing member 52, the on-off of the corresponding liquid outlet pipe 3 is realized.

[0041] This solution does not uniquely define the specific structure of the elastic sealing member 52. Specifically, in this embodiment, the elastic sealing member 52 is a rubber ring. In some other embodiments, the elastic sealing member 52 can be a rubber ball, a silica gel ball, a rubber pad, a silica gel pad or a silica gel ring.

[0042] In order to facilitate the reset of the elastic sealing member 52, one feasible solution is: the valve core 51 is connected with a reset member 53 and the reset member 53 is used to push the elastic sealing member 52 towards the liquid outlet pipe 3. When this solution is adopted, the elastic sealing member 52 is pushed towards the liquid outlet pipe 3 by the reset member 53 to realize the reset and blockage of the liquid outlet pipe 3.

[0043] This solution does not uniquely define the specific structure of the reset member 53. Specifically, in this embodiment, the reset member 53 is a spring. In some other embodiments, the reset member 53 can be a spring sheet.

[0044] Refer to Figure 1 and Figure 3 , this solution does not uniquely define the driving mode of the elastic sealing member 52. One feasible solution is: a traction assembly 6 for pulling the valve core 51 is installed on the sealing structure 5. When this solution is adopted, the valve core 51 is pulled by the traction assembly 6, and then the elastic sealing member 52 is separated from the inner wall of the liquid outlet pipe 3 to facilitate the liquid to flow out of the liquid outlet pipe 3.

[0045] Referring to Figure 4 and Figure 5 , the specific structure of the traction assembly 6 is not uniquely defined in this solution. One feasible solution is that the traction assembly 6 includes a coil 61 and an iron core 62 disposed within the coil 61. The coil 61 is electrically connected to the controller. When this solution is adopted, direct contact between the traction assembly 6 and the valve core 51 can be avoided, improving the sealing performance and service life.

[0046] Optionally, a terminal 63 connected to the coil 61 is formed on the sealing structure 5. When this solution is adopted, it is convenient to electrically connect the coil 61 to the controller.

[0047] To facilitate the replacement of the sealing structure 5, one feasible solution is that the sealing structure 5 is detachably mounted on the liquid outlet pipe 3. When this solution is adopted, it is convenient to disassemble and replace the sealing structure 5.

[0048] Preferably, a nut 54 is formed on the sealing structure 5. When this solution is adopted, the sealing structure 5 can be conveniently and quickly installed or disassembled by operating a wrench.

[0049] The working principle of this embodiment:

[0050] The coil 61 on the designated liquid outlet pipe 3 is energized by the controller, magnetizing the iron core 62 and pulling the valve core 51, so that the elastic seal 52 is separated from the inner wall of the liquid outlet pipe 3, facilitating the outflow of liquid from the designated liquid outlet pipe 3; when the controller cuts off the power supply to the coil 61, the corresponding iron core 62 demagnetizes, and under the action of the reset member 53, the elastic seal 52 is pushed towards the inner wall of the liquid outlet pipe 3, causing the elastic seal 52 to reset and block the liquid outlet pipe 3.

[0051] To solve the problem of cumbersome control process, in this solution, each sealing structure 5 is controlled separately by the controller. Compared with traditional multi-channel valves, it avoids operating the handwheels corresponding to the valve cores one by one, simplifies the control process, and solves the problem of cumbersome control process.

[0052] To reset the elastic seal 52, in this solution, since the valve core 51 is connected with a reset member 53 and the reset member 53 is used to push the elastic seal 52 towards the liquid outlet pipe 3, the elastic seal 52 is pushed towards the liquid outlet pipe 3 by the reset member 53 to achieve the reset of the elastic seal 52 and block the liquid outlet pipe 3.

[0053] To improve the sealing performance, in this solution, since the traction assembly 6 includes a coil 61 and an iron core 62 disposed within the coil 61, and the coil 61 is electrically connected to the controller, direct contact between the traction assembly 6 and the valve core 51 can be avoided, improving the sealing performance and service life.

[0054] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
