Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly relates to a filtering electric two-way valve. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters of the transported medium. Through the valve, the flow rate of the fluid transported in the pipeline can be quickly controlled, and the opening and closing of the pipeline can be controlled. It is widely used in life or production work. In the industrial field, a large amount of raw material fluid needs to be transported through pipelines. In order to better control the flow rate and transportation of the raw material fluid, workers will install valves on the pipelines, and then control the pipeline transportation through the valves, effectively improving the controllability of the pipeline transportation. Moreover, it only needs to be rotated to quickly open, close and control the fluid flow rate, with simple and convenient operation and strong applicability.

[0003] An automatic valve is additionally provided with an automatic motor on the valve core of the valve. The automatic motor is used to drive the valve core to rotate to open and close. At the same time, the signal of the valve opening and closing can be transmitted to the automatic motor through an external signal line, with a higher degree of automation, enabling the valve to automatically open and close according to requirements, which is more convenient for control when a large number of valves are used in combination.

[0004] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the existing automatic valve is in use, if the fluid in the pipeline contains a large amount of particulate matter, it is very easy for the fluid to carry the particulate matter and impact the valve core, causing the particulate matter to adhere to the surface of the valve core. Then, during use, it is easy for the valve core to be stuck due to the adhered particulate matter. At the same time, when the valve core is opened and closed, it is very easy for the particulate matter to fill the space between the valve core and the valve body, resulting in increased wear of the valve core and easy damage. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a filtering electric two-way valve that is not easily stuck and the valve core is not easily damaged in view of the defects and deficiencies of the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: a filtering electric two-way valve, including a valve body with a water flow inner cavity and an automatic motor arranged on the top of the valve body. A lifting rod penetrating the top of the valve body is arranged at the bottom of the automatic motor. A valve core that fits with the inner wall of the valve body and closes the inner cavity of the valve body is arranged at the bottom end of the lifting rod. A filtering structure is arranged at the edge position of the inner wall of the valve body where the valve core is located. The minimum inner surface diameter of the filtering structure is larger than the outer diameter of the valve core. After the water flow passes through the filtering structure, the contained particulate impurities are separated and left on the filtering structure.

[0007] Further improvement is: an inspection opening is arranged on the bottom surface of the valve body, and a closing plate for detachably sealing the inspection opening is also arranged on the bottom surface of the valve body.

[0008] Further improvements are as follows: The filtering structure includes a filter cover disposed at the edge position of the valve core on the inner wall of the valve body and an outwardly convex filter cover disposed in the middle section of the filter cover. The cross-section of the outwardly convex filter cover is an arc-shaped filter piece structure.

[0009] Further improvements are as follows: The inner wall of the outwardly convex filter cover is provided with a deformed water pressure piece made of an elastic material.

[0010] Further improvements are as follows: A swinging ball is embedded in the middle section of the deformed water pressure piece.

[0011] Further improvements are as follows: The swinging ball includes a swinging sphere embedded in the middle section of the deformed water pressure piece and a plurality of hemispherical concentrated bumps arranged on the outer wall of the swinging sphere.

[0012] Further improvements are as follows: A plurality of elliptical rolling grooves are provided in the swinging sphere, and a plurality of freely rolling balls are provided in the rolling grooves.

[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When the water flow enters the valve body, the filter cover of the filtering structure cooperates with the outwardly convex filter cover to separate the particulate impurities in the water flow from the water flow and retain them on the filtering structure. At the same time, the shape of the arc-shaped filter piece of the outwardly convex filter cover causes the particulate impurities retained on it to move towards its upper and lower edges under the pushing action of the water flow, thereby ensuring its smoothness. After the valve is opened and the water flow enters, the water flow thrust causes the deformed water pressure piece to deform. After the valve is closed, it swings and beats the outwardly convex filter cover, thereby loosening and shaking off the particulate matter attached to its surface. Thus, while the particulate matter in the water flow is blocked and separated to protect the valve core, the maintenance period is extended and less maintenance is required.

[0018] The present utility model will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Referring to Figures 1 - 3 As shown, the technical solution adopted in this specific embodiment is: a filter type electric two-way valve, including a valve body 1 provided with a water flow inner cavity and an automatic motor 4 arranged on the top of the valve body 1. A lifting rod 2 penetrating the top of the valve body 1 is arranged at the bottom of the automatic motor 4. A valve core 3 that fits against the inner wall of the valve body 1 and closes the inner cavity of the valve body 1 is arranged at the bottom end of the lifting rod 2. A filtering structure 6 is arranged at the edge position of the valve core 3 on the inner wall of the valve body 1. The filtering structure 6 includes a filter cover 61 arranged at the edge position of the valve core 3 on the inner wall of the valve body 1 and an outwardly convex filter cover 62 arranged in the middle section of the filter cover 61. The cross-section of the outwardly convex filter cover 62 is an arc-shaped filter piece structure. The minimum inner surface diameter of the filtering structure 6 is larger than the outer diameter of the valve core 3. After the water flow passes through the filtering structure 6, the particulate impurities contained in it are separated and left on the filtering structure 6. When in use, the valve body 1 of the automatic valve is installed in the pipeline, and then the automatic motor 4 can receive an electric signal to control the lifting and lowering of the lifting rod 2, thereby making the valve core 3 rise and fall simultaneously, and further controlling the opening and closing of the water flow inner cavity of the valve body 1. After the water flow enters the valve body 1, if there are particulate matters in the water flow, when the particulate matters reach the filter cover 61 and the outwardly convex filter cover 62 of the filtering structure 6, the particulate matters contained in it will be left on the filter cover 61 and the outwardly convex filter cover 62, while the water flow can pass through and continue to flow. At the same time, the arc-shaped filter piece shape of the outwardly convex filter cover 62 is used to make the particulate impurities remaining on it move towards its upper and lower edges under the pushing action of the water flow, thereby ensuring its smoothness. Thus, the particulate matters in the water flow are blocked and separated, protecting the valve core 3;

[0020] An inspection opening is provided at the bottom surface of the valve body 1, and a closing plate 5 for detachably sealing the inspection opening is further arranged at the bottom surface of the valve body 1, which is beneficial for quickly performing inspection and cleaning only by removing the closing plate 5 when cleaning and maintaining the inner cavity of the valve body 1, and the use and maintenance are more convenient;

[0021] A deformation water pressure piece 63 made of an elastic material is arranged on the inner wall of the outwardly convex filter cover 62, which is beneficial for deforming it under the water flow pressure when the water flow passes through, and then after the water flow stops flowing, the deformation elastic force generated by the water pressure deformation piece 63 makes the water pressure deformation piece 63 swing and strike the outwardly convex filter cover 62, thereby making the outwardly convex filter cover 62 vibrate when struck and shaking off the attached particulate impurities, making its smoothness better;

[0022] A swing ball 64 is embedded in the middle section of the deformable water pressure sheet 63. The swing ball 64 includes a swing ball body 641 embedded in the middle section of the deformable water pressure sheet 63 and a number of hemispherical concentrated bumps 642 arranged on the outer wall of the swing ball body 641. During the process of the water pressure deformation sheet 63 deforming and restoring its swing, the concentration of impact is improved and the impact force is increased through the swing ball body 641, and the concentrated bumps 642 are coordinated to further concentrate the impact, so that the outer convex filter cover 62 is subjected to a greater amplitude of impact, and the particulate impurities attached thereto are more easily peeled off;

[0023] A number of elliptical rolling grooves 643 are provided in the swing ball body 641, and a number of freely rolling balls 644 are provided in the rolling grooves 643. When the swing ball body 641 swings, it is beneficial for the balls 644 to roll in the rolling grooves 643 by inertia, thereby generating repeated vibrations, so as to further loosen the particulate impurities attached to the outer convex filter cover 62 through the vibrations, making it easier to fall off and further extending the cleaning and maintenance cycle.

[0024] The working principle of the present utility model: When the present utility model is in use, the valve body 1 of the automatic valve is installed in the pipeline, and then the automatic motor 4 can receive an electrical signal to control the lifting rod 2 to rise and fall, thereby causing the valve core 3 to rise and fall simultaneously, and then controlling the opening and closing of the water flow cavity of the valve body 1. After the water flow enters the valve body 1, if the water flow contains particulate matter, when the particulate matter reaches the filter cover 61 and the outer convex filter cover 62 of the filtering structure 6, the particulate matter contained therein will remain on the filter cover 61 and the outer convex filter cover 62, while the water flow can pass through and continue to flow. At the same time, the shape of the arc-shaped filter piece of the outer convex filter cover 62 is used to make the particulate impurities remaining thereon move towards its upper and lower edges under the action of the water flow, thereby ensuring its smoothness, so that the particulate matter in the water flow is blocked and separated, protecting the valve core 3.
