Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a solenoid valve. Background Technology
[0002] Current two-way solenoid valves are usually normally closed. If the solenoid valve is energized for a long time, it will generate a lot of heat. Firstly, it wastes electricity and is not energy-efficient. Secondly, the heat generated by the solenoid valve will have an adverse effect on some media passing through it. In addition, the valve body of the current solenoid valve is subjected to pressure for a long time when it achieves flow throttling, which leads to structural instability. Therefore, a new solenoid valve is designed to address the above defects. Utility Model Content
[0003] To solve at least one of the problems mentioned above, this utility model provides a solenoid valve.
[0004] The technical solution of this utility model is as follows:
[0005] On one hand, this utility model provides an electromagnetic valve, characterized in that: it includes a valve body, the valve body including adjacent first channels and second channels; a first through hole is opened at the top of the first channel; a second through hole is opened at the top of the second channel; the valve body also has a fluid cavity communicating with the first through hole and the second through hole; a sleeve, connecting and communicating with the fluid cavity; a flow-blocking element, movably disposed at the lower end of the sleeve and capable of blocking the first through hole and / or the second through hole to block the fluid flow in the valve body; an elastic element, disposed in the sleeve and supporting the flow-blocking element; and a driving unit, driving the flow-blocking element to control its up and down movement.
[0006] Furthermore, both the first channel and the second channel extend horizontally; the first channel is the inflow end, the second channel is the outflow end, and the intercepting element is provided corresponding to the first through hole and can block the first through hole; or, both the first channel and the second channel extend horizontally; the first channel is the inflow end, the second channel is the outflow end, and the intercepting element is provided corresponding to the second through hole and can block the second through hole.
[0007] Furthermore, the flow-blocking element can elastically expand and contract in the axial direction of the first through hole and / or the second through hole.
[0008] Furthermore, the flow-blocking component includes a connecting part, a first spring, and a pressing part. The pressing part is disposed relative to the first through hole and / or the second through hole and can be used to block it. The connecting part is connected to the driving unit and can move up and down. The first spring is connected between the connecting part and the pressing part.
[0009] Furthermore, the pressing part is configured as an elastic pad.
[0010] Furthermore, the connecting portion has a groove on the side facing the pressing portion and the first spring is embedded in the groove; and / or, the pressing portion is movably embedded in the connecting portion and connected to the connecting portion through the first spring.
[0011] Furthermore, the driving unit includes a stationary iron core, a moving iron core, a pin, and a coil; the stationary iron core and the moving iron core are arranged at intervals from bottom to top inside the sleeve; the first end of the pin is connected to the moving iron core, and the second end of the pin passes through the stationary iron core and is connected to the throttling element; the coil is sleeved on the outside of the sleeve.
[0012] Furthermore, a fixing member is connected to the upper end of the sleeve, and the fixing member is positioned on the side of the moving iron core away from the stationary iron core.
[0013] Furthermore, the sleeve and the valve body are fixedly connected by a pressure cap.
[0014] Furthermore, a partition is provided between the first channel and the second channel of the valve body to allow communication only through the fluid cavity.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] The solenoid valve of this utility model has a sleeve connected to the valve body. The lower end of the sleeve is driven by a drive unit to connect a flow-stopping element to control its up-and-down movement. When the flow-stopping element moves upward away from the first or second through hole, the first channel and the second channel are connected. When the flow-stopping element moves downward until it blocks the first and / or second through hole, the first channel and the second channel are disconnected. An elastic element is provided inside the sleeve to support the flow-stopping element and leave a gap between it and the first or second through hole to ensure that it is normally open. This can avoid the solenoid valve or the fluid medium itself from being affected by long-term energization and heat generation. Furthermore, by opening the first and second through holes at the top of the first and second channels respectively and connecting them through a fluid cavity, when achieving flow closure, it is only necessary to close the first or second through hole from the top with the flow-stopping element. Compared with directly setting the flow-stopping element in the channel to isolate it, it can avoid the flow-stopping element directly bearing the fluid pressure in the channel for a long time, thereby improving its sealing stability and service life.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0028] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.
[0029] This application discloses an electromagnetic valve, including a valve body 100, which includes an adjacent first channel 110 and a second channel 120; a first through hole 111 is formed at the top of the first channel 110; a second through hole 121 is formed at the top of the second channel 120; the valve body 100 also has a fluid cavity 130 communicating with the first through hole 111 and the second through hole 121; a sleeve 200 is connected to the valve body 100, and the sleeve 200 is connected to and communicates with the fluid cavity 130; a flow-blocking member 300 is movably provided at the lower end of the sleeve 200, which can block the first through hole 111 and / or the second through hole 121 to block the fluid flow in the valve body 100; an elastic member 700 is provided inside the sleeve 200 to support the flow-blocking member 300 so that there is a gap between it and the first through hole 111 or the second through hole 121; the flow-blocking member 300 is drivenly connected to a drive unit 400 so that the drive unit 400 controls the flow-blocking member 300 to move up and down.
[0030] In this embodiment, the valve body 100 includes adjacent first channels 110 and second channels 120 for fluid flow. A first through-hole 111 is formed at the top of the first channel 110; a second through-hole 121 is formed at the top of the second channel 120. The valve body 100 also has a fluid cavity 130 connecting the first through-hole 111 and the second through-hole 121. That is, the first channel 110 and the second channel 120 are connected through the fluid cavity 130. If either the first through-hole 111 or the second through-hole 121 is closed, the connection between the first channel 110 and the second channel 120 is broken, and the fluid can no longer flow. A sleeve 200 is connected to the valve body 100. The lower end of the sleeve 200 is driven by a drive unit 400 to connect a flow-stopping member 300 to control its vertical movement. When the flow-stopping member 300 moves upward away from the first through-hole 111 or the second through-hole 121, the first channel 111 and the second channel 120 are connected. When the flow-stopping member 300 moves down until it blocks the first through hole 111 and / or the second through hole 121, the first channel 111 and the second channel 120 are disconnected. In the initial state, the sleeve 200 is provided with an elastic member 700 to support the flow-stopping member 300 so that there is a gap between it and the first through hole 111 or the second through hole 121, ensuring that it is normally open. This can avoid the solenoid valve or the fluid medium itself from being affected by long-term energization and heating. In addition, by opening the first through hole 111 and the second through hole 121 at the top of the first channel 110 and the second channel 120 respectively and connecting them through the fluid cavity 130, when flow-stopping is achieved, it is only necessary to close the first through hole 111 or the second through hole 121 from the top with the flow-stopping member 300. Compared with the flow-stopping member 300 being directly placed in the channel to isolate it, it can avoid the flow-stopping member 300 directly bearing the fluid pressure in the channel for a long time, thereby improving its sealing stability and service life.
[0031] Wherein, the flow-blocking element 300 can block the first through hole 111 and / or the second through hole 121 to block the fluid flow in the valve body 100, which should be understood as the flow-blocking element 300 blocking at least one of the first through hole 111 and the second through hole 121.
[0032] The elastic element 700 can be installed, for example, on the outside or upper side of the throttling element 300 to connect the sleeve 200 and the throttling element 300. The elastic element 700 can be configured as a spring.
[0033] In an optional or preferred embodiment, both the first channel 110 and the second channel 120 extend in the horizontal direction; the first channel 110 is the inflow end, the second channel 120 is the outflow end, and the interceptor 300 is set to correspond to the second through hole 121 and can block the first through hole 111.
[0034] In this embodiment, an example is given as follows: when the first channel 110 is the inflow end and the second channel 120 is the outflow end, the fluid flows through the first channel 110 and then flows to the first through hole 111, where it is blocked by the flow cut-off member 300; optionally, a partition is provided between the first channel 110 and the second channel 120 of the valve body 100 so that they can communicate only through the fluid cavity 130.
[0035] In an optional or preferred embodiment, both the first channel 110 and the second channel 120 extend in the horizontal direction; the first channel 110 is the inflow end, the second channel 120 is the outflow end, and the interceptor 300 is set to correspond to the second through hole 121 and can block the second through hole 121.
[0036] In this embodiment, an example is given as follows: when the first channel 110 is the inflow end and the second channel 120 is the outflow end, the direction of the fluid is as follows: the fluid first flows to the right through the first channel 110, and then flows upward through the first through hole 111 and enters the fluid cavity 130. Since the second through hole 121 is blocked by the flow-blocking device 300 at this time, and part of the pressure of the fluid in the fluid cavity 130 is downward, the seal between the flow-blocking device 300 and the second through hole 121 is more stable.
[0037] In an optional or preferred embodiment, the flow-blocking member 300 is axially elastically expandable and contractible in the first through hole 111 and / or the second through hole 121, thereby improving the sealing connection between the flow-blocking member 300 and the first through hole 111 and / or the second through hole 121.
[0038] In an optional or preferred embodiment, the flow-blocking component 300 includes a connecting portion 310, a first spring 320, and a pressing portion 330. The pressing portion 330 is disposed relative to the first through hole 111 and / or the second through hole 121 and can be used to block it. The connecting portion 310 is connected to the driving unit 400 and can move up and down. The first spring 320 is connected between the connecting portion 310 and the pressing portion 330.
[0039] In this embodiment, the first spring 320 ensures a tighter connection between the pressing part 330 and the first through hole 111 and / or the second through hole 121 when driven by the driving unit 400, without causing rigid impact and effectively preventing damage from collision. The pressing part 330 can be configured as an elastic pad to further improve its sealing performance to the through hole. Specifically, the elastic pad can be, for example, a rubber pad. In some embodiments, the elastic pad has a large upper surface area and a small side surface area, so that when sealing the second through hole 121, it receives a greater downward force to ensure a good seal to the second through hole 121.
[0040] In an optional or preferred embodiment, the connecting portion 310 has a groove on the side facing the pressing portion 330, and a first spring 320 is embedded in the groove to achieve stable installation of the first spring 320; the pressing portion 330 is movably embedded in the connecting portion 310 and connected to the connecting portion 310 through the first spring 320, thereby guiding the pressing portion 330 to move within the connecting portion 310, which can achieve stable docking and sealing of the first through hole 111 and / or the second through hole 121.
[0041] In an optional or preferred embodiment, the drive unit 400 includes a stationary iron core 410, a moving iron core 420, a pin 430, and a coil 440; the stationary iron core 410 and the moving iron core 420 are spaced apart from bottom to top inside the sleeve 200; the first end of the pin 430 is connected to the moving iron core 420, and the second end of the pin 430 passes through the stationary iron core 410 and is connected to the throttling member 300; the coil 440 is sleeved on the outside of the sleeve 200.
[0042] When in use, the coil 440 is energized, and the moving iron core 420 drives the throttling component 300 to move downward through the pin 430, thereby blocking the first through hole 111 and / or the second through hole 121.
[0043] In an optional or preferred embodiment, a fixing member 500 is connected to the upper end of the sleeve 200. The fixing member 500 is disposed on the side of the moving iron core 420 away from the stationary iron core 410 to limit the moving iron core 420.
[0044] In an optional or preferred embodiment, the sleeve 200 and the valve body 100 are fixedly connected by a pressure cap 600, so that the assembly and disassembly of the sleeve 200 and the valve body 100 are simpler and more stable.
