Description

Technical Field

[0001] This utility model relates to the field of valves, specifically to a water flow pipeline valve for a cleaning machine. Background Technology

[0002] Bottle washers are common laboratory equipment used for the standardized cleaning of reagent bottles or other containers. Cleaning reagent bottles requires the combined use of air and water to clean the inside of the bottles. For simplicity, both air and water are sprayed from a single nozzle, and then converged into a conduit before reaching the nozzle.

[0003] To prevent water and air from mixing, a water-air separation structure is required. For example, Chinese utility model patent application number 202023007793.X discloses a water-air separation structure for a bottle washing machine that provides stable sealing and easy flow control. This structure mainly consists of a shell, an air inlet, a water inlet, an outlet, a diaphragm, a valve plate, a drain outlet, and a pin. The bottom surface of the cavity inside the shell is made into a plane, and the water inlet and air inlet are located on this plane. The diaphragm seals one of the water inlet or air inlet. During water or air delivery, the diaphragm remains horizontal and does not easily swing. Water pressure or air pressure can be used to enhance the sealing effect of the diaphragm. Furthermore, the drain outlet reduces the number of cold water pipes and facilitates pipe layout.

[0004] However, the patent has the following problems in practical application: the valve plate will extend into the inside of the housing. In order to prevent the valve plate from affecting the rotation of the diaphragm, the inside of the housing needs more space, which increases the volume of the water-air separation structure and also increases the production cost of the water-air separation structure. Utility Model Content

[0005] The purpose of this utility model is to provide a water flow pipeline valve for a cleaning machine, which solves the problem that the valve plate of the existing water-air separation structure extends into the inside of the shell. In order to prevent the valve plate from affecting the rotation of the diaphragm, the inside of the shell needs more space, which increases the volume of the water-air separation structure and also increases the production cost of the water-air separation structure.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, this utility model provides a water flow pipeline valve for a cleaning machine, comprising: a valve body, a drain outlet on one side of the valve body, a limiting plate on the inner side of the valve body, the limiting plate having a porous structure, the limiting plate being fixedly connected to the inner side of the drain outlet, a valve plate being provided inside the drain outlet, and a drainage control mechanism being provided inside the drain outlet, the drainage control mechanism being used to drive the valve plate to move so that the valve plate is separated from or engaged with the drain outlet.

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0026] Figure 1 This is a schematic diagram of the overall structure of the water flow pipeline valve of a cleaning machine according to one embodiment of this utility model. Figure 1 As shown, this embodiment provides a water flow pipeline valve for a cleaning machine, including: a valve body 1, a drain outlet 2 on one side of the valve body 1, a limiting plate 3 on the inner side of the valve body 1, the limiting plate 3 having a porous structure, the limiting plate 3 being fixedly connected to the inner side of the drain outlet 2, a valve plate 4 being provided inside the drain outlet 2, and a drainage control mechanism being provided inside the drain outlet 2, the drainage control mechanism being used to drive the valve plate 4 to move so that the valve plate 4 is separated from or engaged with the drain outlet 2.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the valve body 1 is also provided with a water inlet 19, an air inlet 20 and an outlet 21. The water inlet 19 and the air inlet 20 are located on the same side of the valve body 1. A water-air diversion diaphragm 22 is provided on the inner side of the valve body 1 between the water inlet 19 and the air inlet 20. The water-air diversion diaphragm 22 is hinged to the inner wall of the valve body 1.

[0028] In this embodiment, a perforated limiting plate 3 is provided inside the drain outlet 2 of the valve body 1. The limiting plate 3 can limit the movement of the valve plate 4, preventing the valve plate 4 from moving into the interior of the valve body 1. The movement of the valve plate 4 will not affect the internal components of the valve body 1. Since the rotation of the water-air diversion diaphragm 22 requires a certain amount of space, when the valve plate 4 cannot move into the interior of the valve body 1, it will not block the rotation of the water-air diversion diaphragm 22. This improves the space utilization rate inside the valve body 1, making the volume of the cleaning machine water flow pipeline valve smaller and reducing the production cost of the cleaning machine water flow pipeline valve.

[0029] As a further optimization of this embodiment, such as Figure 3As shown, the drainage control mechanism includes: a connecting pipe 5 connected to the outside of the drain outlet 2, an installation ring 6 fixedly connected to the end of the connecting pipe 5, a connecting plate 7 provided radially on the installation ring 6, both ends of the connecting plate 7 fixedly connected to the installation ring 6, a push rod 8 passing through the middle of the connecting plate 7, one end of the push rod 8 connected to the middle of the valve plate 4, a limiting ring 9 provided at the other end of the push rod 8, a spring 10 sleeved on the push rod 8 between the limiting ring 9 and the connecting plate 7, both ends of the spring 10 being fixedly connected to the connecting plate 7 and the limiting ring 9 respectively, and the spring 10 being in a stretched state.

[0030] In this embodiment, the limiting ring 9 is a nut, which is screwed onto the end of the push rod 8. When it is necessary to drain the water in the valve body 1, the push rod 8 is pushed upward. At this time, the valve plate 4 is separated from the drain port 2 (the spring 10 is in a stretched state), and the water in the valve body 1 can be drained from the drain port 2. When the push rod 8 is released, the valve plate 4 automatically resets under the elastic force of the spring 10, and the drain port 2 is blocked again.

[0031] As a further optimization of this embodiment, in order to prevent accidental contact with the push rod 8 and separation of the valve plate 4 from the drain outlet 2, a sleeve 11 is provided inside the connecting pipe 5. The length of the sleeve 11 is greater than the length of the push rod 8. The sleeve 11 is used to lift the valve plate 4. When the length of the sleeve 11 is greater than the length of the push rod 8, accidental contact with the push rod 8 will not occur.

[0032] In this embodiment, the sleeve 11 can lift the valve plate 4 in the following two ways:

[0033] Firstly: such as Figure 3 As shown, the outer wall of the sleeve 11 is provided with external threads, the inner wall of the connecting pipe 5 is provided with internal threads, the sleeve 11 is screwed into the connecting pipe 5, and the inner end of the sleeve 11 is provided with a pair of lifting parts 12. Therefore, when the sleeve 11 is rotated, the lifting parts 12 of the sleeve 11 can lift the valve plate 4.

[0034] Secondly: such as Figure 4 and Figure 5 As shown, the outer wall of the sleeve 11 is provided with a protruding ring 13, the inner wall of the connecting pipe 5 is provided with a stepped surface, the protruding ring 13 is connected to the stepped surface, the outer end face of the connecting pipe 5 is provided with an annular groove 14, and the inner end face of the connecting pipe 5 is provided with a plurality of through holes 15 communicating with the annular groove 14. A strip-shaped column 16 is inserted into each of the through holes 15, and one end of the strip-shaped column 16 extends into the annular groove 14.

[0035] A swivel sleeve 17 is rotatably connected to the outer end of the connecting pipe 5. One end of the swivel sleeve 17 is inserted into the annular groove 14. A plurality of arc-shaped protrusions 18 are provided on one end of the swivel sleeve 17. The arc-shaped protrusions 18 are used to push the other end of the strip column 16 out of the through hole 15 during the rotation of the swivel sleeve 17.

[0036] In this embodiment, when the sleeve 17 is rotated, the arc-shaped protrusion 18 on the sleeve 17 can lift the strip column 16, and the strip column 16 can then lift the valve plate 4, thereby separating the valve plate 4 from the drain outlet 2.

[0037] In this embodiment, four through holes 15 are provided, and the four through holes 15 are distributed at equal intervals along the circumference of the connecting pipe 5; at this time, there are also four strip columns 16, which can make the thrust on the valve plate 4 balanced, and avoid the valve plate 4 from deforming due to uneven force, which would cause the sealing failure after the valve plate 4 comes into contact with the drain outlet 2.

[0038] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
