Description

Technical Field

[0001] The invention relates to the technical field of fire butterfly valves, in particular to an electric fire butterfly valve with a filtering function. Background Art

[0002] As an important equipment in fire fighting, the quality of the electric fire butterfly valve determines the overall quality of fire fighting liquid transmission. It regulates the liquid flow stably through electric drive. For example, a patent with publication number CN210949907U discloses a fire butterfly valve with quick plug-in connection, in which a flange integrated with the butterfly valve body is provided on the left side, the flange is inserted into a suction pipe cover with a middle part that is recessed inward, the suction pipe cover is clamped in the flange through a copper latch, a butterfly valve sealing ring is provided outside the disc plate of the butterfly valve body for sealing, a suction pipe sealing ring is provided inside the flange for sealing, and the butterfly valve body is fixed on a fire truck; when the disc plate is in a closed state, the suction pipe cover is located in the flange; when the disc plate is in an open state through an actuator, the handle is rotated outward, thereby rotating the threaded rod of the copper latch outward, and the copper latch is away from the middle part of the suction pipe cover that is recessed; Another example is a fire signal butterfly valve with an alarm device in the patent with publication number CN212338374U, in which the anti-misoperation mechanism includes a second fixed plate, a first touch plate and a second touch plate, and the second fixed plate is movably connected to the rear of the top of the first fixed plate, which relates to the technical field of butterfly valves. When the valve is closed by mistake, the first touch plate contacts the second touch plate, so that the first touch plate, the second touch plate, the first electric telescopic rod and the second electric telescopic rod are in a closed circuit. Under the action of the control box, the first electric telescopic rod and the second electric telescopic rod are controlled to extend, driving the disc plate to rotate, thereby opening the through slot; For example, the patent with publication number CN220956865U discloses a linkage type quick-opening electric butterfly valve for a fire water system, including a valve body, one end of the bolt being threadedly connected to a driving mechanism. Through the setting of the sealing mechanism, when the butterfly plate fits with the valve body, the water body is blocked by the butterfly plate at one end of the valve body. Since the first sealing gasket is embedded in the first circular groove, and the second sealing gasket is embedded in the second circular groove, the position of the first circular groove is aligned with the position of the second circular groove, so that one side of the surface of the first sealing gasket fits one side of the surface of the second sealing gasket. Since the arc plate is fixedly connected to one side of the inner wall of the valve body, the third circular groove is opened on one side of the surface of the arc plate, and the third sealing gasket is embedded in the third circular groove, so that one side of the surface of the butterfly plate fits one side of the surface of the third sealing gasket. Most of the above-mentioned existing technologies have improved their overall structure, while the existing electric fire butterfly valves are mostly through-type conduction structures during operation. Since fire water requires relatively pure liquid, it is unable to filter and process the transmitted liquid flow stably and efficiently, resulting in the discharge water quality affecting firefighting work, and thus having certain usage limitations. Summary of the invention

[0007] Furthermore, when the built-in movable filter assembly moves along the inner side of the external reserved docking pipe in contact with the water flow force, its end will simultaneously apply pressure to the contacting abutment, and the abutment drives the docking nesting part through the reserved traction rope to form traction.

[0008] Furthermore, when the docking nested parts are subjected to force, the middle and lower ends of the elastic docking layer are driven to form elastic activities, and the middle end of the elastic docking layer is subjected to force and deforms along the outer side of the external reserved docking pipe. The elastic docking layer is symmetrically distributed about the center point of the external reserved docking pipe.

[0009] Furthermore, an auxiliary supply structure is provided on the outside of the external reserved docking pipe, and the quality of the transmitted liquid of the external reserved docking pipe is controlled by the auxiliary supply structure; the auxiliary supply structure is provided with a reserved first corrugated liquid capsule, and the reserved first corrugated liquid capsule is docked on the inner wall of the external reserved docking pipe, the outside of the external reserved docking pipe is docked with a supply pipe, and the supply pipe passes through the inner wall of the external reserved docking pipe, the outside of the external reserved docking pipe is docked with an external storage component, and the inner wall of the external storage component is bonded with a reserved second corrugated liquid capsule, and the reserved second corrugated liquid capsule and the supply pipe are connected to each other.

[0010] Furthermore, an internal fitting component is nested on the inner wall of the external storage component, and the internal fitting component is docked with the outer side of the reserved second corrugated liquid bag, a discharge pipe is passed through the outer end of the external storage component, and the discharge pipe passes through the inner wall of the external reserved docking pipe, and an elastic sealing structure is provided on the inner wall of the discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The electric fire butterfly valve with filtering function is provided with a movable built-in movable filtering component. As the internal liquid of the electric fire butterfly valve body is transmitted, the built-in movable filtering component in contact with the driving force of the liquid will move synchronously along the inner side of the external reserved docking pipe, and then cooperate with the relatively fixed docking wire rope at the end to drive the vertical and horizontal wires of the internal interwoven structure of the docked built-in movable filtering component to be stressed, forming a gathered working state, thereby reducing the filter hole area of ​​the built-in movable filtering component, performing efficient filtering processing during the high-speed flow transmission process, effectively controlling the filtering range according to the water flow size of the flow transmission, stably and efficiently filtering the transmitted liquid flow, and avoiding the discharged water quality from affecting the firefighting work; Furthermore, an auxiliary guiding structure is provided, through which the flow area of ​​the external reserved docking pipe is adaptively adjusted.

During the inward movement of the resisting docking piece, pressure is applied to the contacting reserved first corrugated liquid bag, so that the reserved first corrugated liquid bag supplies to the inside of the reserved second corrugated liquid bag through the supply pipe, thereby allowing the reserved second corrugated liquid bag to expand and push the built-in fitting component to fit along the inner wall of the external storage component. The liquid stored in the external storage component is supplied to the outside through the discharge pipe. According to the activity state of the water flow, the inside of the external reserved docking pipe is effectively treated with water purifiers and the like, so as to ensure the quality of the transmitted water and improve the practicability of the device.
