Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve with a sewage discharge function. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium.

[0003] According to CN211398605U, a butterfly valve with a sewage discharge function is disclosed. This technology discloses "a butterfly valve with a sewage discharge function, including a valve assembly. The valve assembly includes an upper housing and a lower housing detachably connected to the upper housing. A first bearing is installed at the upper end of the upper housing, and a vertically arranged valve stem is connected to the inner ring of the first bearing. A valve handle is located above the upper housing, and the valve handle is connected to the upper end of the valve stem. A left valve leaf and a right valve leaf are installed at both ends of the valve stem. An upper valve leaf is installed inside the upper housing." The system features a baffle bar, with an upper baffle bar installed in front of the right valve leaf. Locking blocks are installed at the lower ends of both sides of the upper housing. A second bearing is installed at the lower end of the lower housing, and the lower end of the valve stem is tightly connected to the second bearing. A lower baffle bar is installed inside the lower housing, positioned behind the left valve leaf. A groove matching the locking block is formed at the upper end of the lower housing. These technical solutions provide the following benefits: "Rotating the valve handle drives the valve stem to rotate for sewage discharge; the upper and lower housings are detachably connected via locking blocks and grooves, allowing for easy cleaning of the valve assembly's interior."

[0004] When it is necessary to clean and drain the inside of the valve, the traditional integral butterfly plate cannot effectively cut off the flow of the medium, which means that the draining operation must be carried out by stopping the machine. This not only affects the continuous operation of the pipeline system, but also the single butterfly plate structure is difficult to form an effective isolation space, so that the deposits cannot be completely removed. They are prone to forming stubborn accumulations at the bottom of the valve cavity and around the sealing surface. Long-term accumulation will seriously affect the sealing performance and service life of the valve. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a valve with a sewage discharge function. By adopting a multi-blade segmented design, synchronous opening and closing are achieved through a linkage mechanism. During sewage discharge, the closed blades form an isolation space, which, combined with high-pressure flushing, enables online sewage discharge, effectively removing deposits and ensuring the safe and efficient operation of the system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve with a sewage discharge function, comprising a valve mechanism for controlling sewage discharge, wherein the valve mechanism comprises:

[0007] Main components, including butterfly valves installed on pipelines;

[0008] The opening and closing assembly includes flanges installed at both ends of the butterfly valve. A first bearing is fixed at the middle of each end of the flange, and a first blade is rotatably installed between the two first bearings. A second bearing is fixed at the upper and lower sides of the middle of each end of the flange, and a second blade is rotatably installed between the two second bearings. A third bearing is fixed at the upper and lower sides of each end of the flange, and a third blade is rotatably installed between the two third bearings. A first support rod is fixed at the front end of each of the first, second, and third blades, and the same first connecting rod is pivotally connected between each first support rod.

[0009] Preferably, the valve mechanism further includes a second support rod fixed to the rear end of the first blade, the second blade, and the third blade, with a second connecting rod pivotally connected between each of the second support rods on the left and right sides.

[0010] Preferably, the main component further includes a flushing port located on the upper part of the butterfly valve body and a drain port located on the lower part of the valve body, wherein the flushing port and the drain port are respectively connected to the valve cavity of the butterfly valve.

[0011] Preferably, the main component further includes a flushing plug threaded onto the flushing port and a drain plug threaded onto the drain port.

[0012] Preferably, the inner wall of the sewage outlet is provided with spiral guide ribs, and the spiral guide ribs are distributed in an involute pattern along the sewage discharge direction to generate a swirling effect during sewage discharge.

[0013] Preferably, the surfaces of the first blade, the second blade, and the third blade are all provided with flow guiding grooves, which are radially distributed along the radial direction of the blade.

[0014] Beneficial effects

[0015] This utility model provides a valve with a sewage discharge function. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] 1. When it is necessary to drain the inside of the butterfly valve, open the internal butterfly plate, close the opening and closing components at both ends to cut off the flow of the medium, then connect the external high-pressure water through the flushing port, and open the drain port. Use gravity and pressure difference to form a directional flushing channel from top to bottom, so that the sediment inside the butterfly valve can be discharged under flushing.

[0018] 2. An external motor can be connected to drive any one of the first, second, and third blades, allowing the first support rod to control the synchronous rotation of the first, second, and third blades in conjunction with the first connecting rod. By dividing the blades of the opening and closing assembly into multiple segments consisting of the first, second, and third blades, the butterfly valve, under normal use, forms a stepped flow channel when open, resulting in a smooth fluid transition and significantly reducing water hammer effects. The independently supported structure of each blade ensures more uniform stress distribution, reduces valve shaft torque, and extends service life. Furthermore, the barrier formed by the opening and closing assembly ensures that the sewage discharge process does not affect the normal operation of the pipeline system, enabling safe and efficient online maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a valve with a sewage discharge function, including a valve mechanism 1 for controlling sewage discharge, the valve mechanism 1 including:

[0026] Main component 11 includes a butterfly valve 111 installed on the pipeline;

[0027] The opening and closing assembly 12 includes flange cylinders 121 installed at the left and right ends of the butterfly valve 111. A first bearing 122 is fixed at the middle of both ends of the flange cylinder 121. A first blade 125 is rotatably installed between the two first bearings 122. A second bearing 123 is fixed at the upper and lower sides of the middle of both ends of the flange cylinder 121. A second blade 126 is rotatably installed between the two second bearings 123. A third bearing 124 is fixed at the upper and lower sides of both ends of the flange cylinder 121. A third blade 127 is rotatably installed between the two third bearings 124. A first support rod 128 is fixed at the front end of the first blade 125, the second blade 126 and the third blade 127. The same first connecting rod 129 is pivotally connected between each first support rod 128.

[0028] In this embodiment, an external motor can be used to drive any one of the first blade 125, the second blade 126, and the third blade 127, so that the first support rod 128, in cooperation with the first connecting rod 129, controls the synchronous rotation of the first blade 125, the second blade 126, and the third blade 127. By dividing the blades of the opening and closing assembly 12 into a multi-segment structure consisting of the first blade 125, the second blade 126, and the third blade 127, the multi-segment arrangement of the opening and closing assembly 12 forms a stepped flow channel when the butterfly valve 111 is in normal use, allowing the fluid to transition smoothly and significantly reducing the water hammer effect. The structure of independent support for each blade makes the force distribution more uniform, reduces valve shaft torque, and extends service life. It also ensures that the cutoff barrier formed by the opening and closing assembly 12 ensures that the sewage discharge process does not affect the normal operation of the pipeline system, achieving safe and efficient online maintenance.

[0029] Specifically, the valve mechanism 1 also includes a second support rod 13 fixed to the rear end of the first blade 125, the second blade 126 and the third blade 127, and a second connecting rod 14 is pivotally connected between each of the second support rods 13 on the left and right sides.

[0030] In this embodiment, when the first blade 125, the second blade 126, and the third blade 127 on one side rotate, the second support rod 13 can drive the first blade 125, the second blade 126, and the third blade 127 on the other side to rotate synchronously with the cooperation of the second connecting rod 14, thereby realizing the synchronous opening and closing of the two-end opening and closing components 12.

[0031] Specifically, the main component 11 also includes a flushing port 112 located on the upper part of the butterfly valve 111 valve body and a drain port 113 located on the lower part of the valve body, wherein the flushing port 112 and the drain port 113 are respectively connected to the valve cavity of the butterfly valve 111.

[0032] In this embodiment, when it is necessary to drain the inside of the butterfly valve 111, the internal butterfly plate is opened and closed by the opening and closing components 12 at both ends to cut off the flow of the medium. Then, the external high-pressure water is connected through the flushing port 112 and the drain port 113 is opened. Gravity and pressure difference are used to form a directional flushing channel from top to bottom, so that the deposits inside the butterfly valve 111 are discharged under flushing.

[0033] Specifically, the main component 11 also includes a flushing plug 114 threaded onto the flushing port 112 and a drain plug 115 threaded onto the drain port 113.

[0034] In this embodiment, when the valve mechanism 1 is operating normally, the flushing plug 114 and the drain plug 115 achieve double sealing through thread pre-tightening force, ensuring the complete closure of the flushing port 112 and the drain port 113.

[0035] Specifically, the inner wall of the sewage outlet 113 is provided with spiral guide ribs, and the spiral guide ribs are distributed in an involute pattern along the sewage discharge direction and are used to generate a swirling effect during sewage discharge.

[0036] In this embodiment, the swirling effect generated by the spiral guide ribs causes the sediment entering the drain 113 to move closely against the pipe wall under the action of centrifugal force, effectively preventing particulate matter from depositing during the drain process. At the same time, the spiral structure with an involute distribution can maintain the smoothness of the drain process and ensure that various impurities can be discharged smoothly.

[0037] Specifically, the surfaces of the first blade 125, the second blade 126, and the third blade 127 are all provided with flow guiding grooves, which are radially distributed along the blade.

[0038] In this embodiment, the fluid is divided into multiple branches and forms vortices when it passes through the flow guide groove. These vortex flows have a continuous scouring effect on the inner wall of the valve body.

[0039] The working principle and usage process of this utility model are as follows: First, an external motor can be connected, and the motor can drive any one of the first blade 125, the second blade 126 and the third blade 127, so that the first support rod 128 controls the first blade 125, the second blade 126 and the third blade 127 to rotate synchronously under the cooperation of the first connecting rod 129.

[0040] Meanwhile, when the first blade 125, the second blade 126, and the third blade 127 on one side rotate, the first blade 125, the second blade 126, and the third blade 127 on the other side can be driven to rotate synchronously through the second support rod 13 in cooperation with the second connecting rod 14, so as to realize the synchronous opening and closing of the two-end opening and closing assembly 12.

[0041] When it is necessary to drain the inside of the butterfly valve 111, the internal butterfly plate is opened and closed by the opening and closing components 12 at both ends to cut off the flow of the medium. Then, the external high-pressure water is connected through the flushing port 112 and the drain port 113 is opened. Gravity and pressure difference are used to form a directional flushing channel from top to bottom, so that the deposits inside the butterfly valve 111 are discharged under flushing.
