Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of two-way valves, in particular to a contactless electric control two-way valve. Background Art
[0002] To improve the reuse rate of medical consumables, some used consumables can be used again after being cleaned, such as guide wires, catheters, and catheter sheaths. During the process of cleaning the consumables, it is not only necessary to ensure that the consumables are cleaned thoroughly, but also to avoid contamination of the cleaning fluid during transmission.
[0003] On cleaning equipment, in order to conveniently control the pressure and flow rate of the cleaning fluid or the return fluid, it is often necessary to set an electric control valve body in the pipeline. Some electric control valve bodies achieve throttling and blocking functions through the cooperation of a valve core and a rubber plunger. Among them, the valve core and the rubber plunger are in direct contact with the fluid. This direct-contact type of electric control valve body is likely to contaminate the consumable cleaning fluid.
[0004] Therefore, there is an urgent need for a contactless electric control two-way valve that can solve one or more of the above problems. Summary of the Utility Model

[0007] The push rod of the electric push rod is connected with a driven push rod, the driven push rod passes through the first through hole and enters the adjustment groove, and the driven push rod presses or loosens the infusion pipeline in the channel.
[0008] In some embodiments, the bracket is provided with an avoidance position recessed away from the push rod.
[0009] In some embodiments, a first hinge hole is provided at the free end of the push rod, a second hinge hole is provided at one end of the driven push rod close to the push rod, and the first hinge hole and the second hinge hole are hinged through a connecting piece.

Detailed Embodiment
[0018] To make the above objects, features, and advantages of the present utility model more comprehensible, the following detailed description of the specific embodiments of the present utility model is provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0019] As Figures 1 - 3 shown, the present utility model discloses a non-contact electric control two-way valve, which includes: a bracket 1, an installation part 10 is provided at the first end of the bracket 1, a first through hole 11 is provided in the installation part 10, and an electric push rod 2 is installed at the second end of the bracket 1;
[0020] The installation part 10 is installed with a valve head 4, the valve head 4 is provided with an adjustment slot 40 docked with the first through hole 11, the valve head 4 is provided with a channel 41, the channel 41 is connected to the adjustment slot 40, and the infusion pipeline penetrates into the channel 41;
[0021] The push rod 20 of the electric push rod 2 is connected to the driven push rod 3. The driven push rod 3 passes through the first through hole 11 and enters the adjustment groove 40, and the driven push rod 3 presses or loosens the infusion pipeline in the channel 41.
[0022] It should be noted that the electric push rod 2 can be an existing common device, such as an electromagnetic push rod assembly or a motor screw push rod assembly. The infusion pipeline inserted into the channel 41 is a flexible rubber pipeline.
[0023] Combined with Figure 3 , during use, the electric push rod 2 drives the driven push rod 3 to move upward, that is, to press the infusion pipeline in the channel 41, thereby reducing the flow rate or closing the control. Furthermore, the electric push rod 2 drives the driven push rod 3 to move downward, that is, to loosen the infusion pipeline in the channel 41, thereby increasing the flow rate or opening the control.
[0024] Specifically, as Figure 2 shown, the bracket 1 is provided with an avoidance position 12 that is recessed away from the push rod 20. The purpose is to leave more installation and movement space and facilitate the passage of other components.
[0025] Specifically, as Figure 2 shown, the free end of the push rod 20 is provided with a first hinge hole 21, and one end of the driven push rod 3 close to the push rod 20 is provided with a second hinge hole 30. The first hinge hole 21 and the second hinge hole 30 are hinged through a connecting piece 31. The purpose is to improve the redundancy during installation and use and avoid jamming.
[0026] Specifically, combined with Figure 3 shown, the valve head 4 is provided with an insertion groove 42. The insertion groove 42 is connected to the channel 41. The infusion pipeline is loaded into the channel 41 through the insertion groove 42. The opening of the insertion groove 42 is smaller than the opening of the channel 41, so that the infusion pipeline can be limited in the channel 41 after being opened. The infusion pipeline can be conveniently loaded and unloaded through the insertion groove 42. Furthermore, the insertion groove 42 is provided at one end of the channel 41 close to the installation part 10. The purpose is to prevent the driven push rod 3 from squeezing the infusion pipeline out of the insertion groove 42 or part of the infusion pipeline from being clamped in the insertion groove 42 when performing the pressing action.
[0027] Particularly, the corners of the channel 41 and the insertion groove 42 need to be chamfered or rounded, and the end faces and corners also need to be deburred to prevent cutting or piercing the infusion pipeline during use. In addition, a limiting mechanism (not shown in the figure) can be provided on the bracket 1 to prevent the driven push rod 3 from moving to an unnecessary position.
[0028] In summary, by controlling the electric push rod to drive the driven push rod to move telescopically, the infusion pipeline in the valve head can be tightened or loosened, thereby realizing the flow regulation and on-off control of the flexible infusion pipeline, and avoiding direct contact with the liquid in the infusion pipeline to ensure that the transported liquid is not contaminated.
[0029] The embodiments described above only represent one or more implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
