Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pumping stations, in particular to a fast start-stop control valve for water conservancy pumping stations. Background Art

[0002] The multifunctional water pump control valve is a common quick start and stop control valve used in water conservancy pumping stations. The multifunctional water pump control valve consists of a main valve, a regulating valve and a takeover system.

[0003] A Chinese patent discloses a multifunctional water pump control valve (authorization announcement number CN216741965U). The utility model uses a filter cartridge to achieve pre-filtration of the filter and the front end of the conduit, and uses the kinetic energy of the medium in the pipeline through an impeller to drive a brush to automatically clean the filter cartridge, thereby solving the problem of easy clogging of the filter.

[0004] Since the impeller in the above device uses the kinetic energy of the medium in the pipeline to rotate, it drives the brush to peel off the stains accumulated on the outer surface of the filter cartridge. However, when the impeller is located on the upper and lower sides of the filter cartridge and is simultaneously subjected to the thrust of the water flow, the impeller can easily slow down or stop rotating due to the thrust of the two water flows, which increases the burden of the brush rotating to remove the stains on the surface of the filter cartridge.

[0005] Therefore, a fast start-stop control valve for a hydraulic pump station is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a quick start-stop control valve for a hydraulic pump station in order to solve the above-mentioned problem, thereby improving the problem that the quick start-stop control valve for a hydraulic pump station with a self-cleaning function has poor cleaning effect and is still easy to clog.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a quick start-stop control valve for a water conservancy pump station, comprising: a valve body, the surface of which is fixedly connected and connected to a filter; a protective device, which is installed inside the valve body, and the connection between the valve body and the filter is arranged on the inner side of the protective device.

[0008] Preferably, the protective device includes a filter cartridge and a water guide box, the filter cartridge is rotatably connected to the inside of the valve body, the communication point between the valve body and the filter is arranged on the inner side of the filter cartridge, the water guide box is fixedly connected to the inside of the valve body, the filter cartridge is arranged inside the water guide box, the inside of the filter cartridge is fixedly connected with a water wheel, the two openings of the water guide box are symmetrically arranged above the axis of the water wheel, the inside of the water guide box is fixedly connected with a brush plate in contact with the filter cartridge, the water guide box can impact the water flow passing through the valve body to the water wheel in a single direction, so that the water wheel drives the filter cartridge to be cleaned by the brush plate in a single direction, which can avoid that both sides of the water wheel are subjected to force at the same time, so as to reduce the probability of the rotation of the water wheel being restrained or even stopped, thereby ensuring the smooth flow of the filter cartridge surface.

[0009] Preferably, the top of the brush plate contacts the lowest point of the filter cartridge, which can reduce the probability of the brushed impurities falling back onto the surface of the filter cartridge, further ensuring the cleanliness of the surface of the filter cartridge.

[0010] Preferably, a sewage outlet is provided at the bottom of the water guide box, and the sewage outlet is arranged below the brush plate, which can guide the brushed impurities out of the water guide box, further ensuring the cleanliness of the filter cartridge surface.

[0011] Preferably, the sewage outlet is arranged at the lowest point of the bottom wall of the water guide box, which can reduce the probability of impurities being retained inside the water guide box, thereby improving the effective discharge rate of impurities.

[0012] Preferably, both ends of the water guide box are fixedly connected and communicated with a water guide bucket, and the vertical cross-section of the water guide bucket is an isosceles trapezoid, which can guide more water into the water guide box to increase the rotational cleaning rate of the filter cartridge.

[0013] Preferably, an annular groove rotatably connected to the filter cartridge is provided inside the valve body, and balls evenly distributed and slidably connected to the annular groove are embedded on the surface of the filter cartridge. The balls are distributed in an annular shape around the axis of the filter cartridge. The annular groove can lock the filter cartridge more stably inside the valve body.

[0014] Preferably, a sealing ring in contact with the annular groove is fixedly connected to the surface of the filter cartridge, and the sealing ring is arranged on the side of the ball bearing close to the water wheel. The sealing ring can prevent impurities in the water flow from entering the annular groove to reduce the rotational resistance of the filter cartridge.

[0015] The beneficial effects of the utility model are:

[0016] 1. The water guide box can direct the water flow through the valve body to impact the water wheel in one direction, so that the water wheel drives the filter cartridge to be cleaned by the brush plate in one direction. This can avoid the two sides of the water wheel being stressed at the same time, thereby reducing the probability of the water wheel rotation being restrained or even stopped, thereby ensuring that the water flow can pass through the filter cartridge smoothly;

[0017] 2. The water guide bucket can guide more water into the water guide box to increase the rotational cleaning rate of the filter cartridge.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a quick start-stop control valve for a water conservancy pump station comprises: a valve body 1, the surface of the valve body 1 is fixedly connected and communicated with a filter 2; a protective device 3, the protective device 3 is installed inside the valve body 1, and the connection between the valve body 1 and the filter 2 is arranged on the inner side of the protective device 3;

[0026] The interior of the valve body 1 is provided with a control chamber, an inlet channel, an outlet channel, a cylinder, an axial strip guide groove, a protrusion, a diaphragm, a valve stem, a main valve flap and an auxiliary valve flap. The number of filters 2, protective devices 3 and annular grooves 11 is two, and one end of the two filters 2 is fixedly connected and communicated with the inlet channel and the outlet channel respectively. The inlet channel and the outlet channel are respectively arranged on the inner side of the filter cartridges 31 in the two protective devices 3. A check valve is fixedly connected between the filter 2 fixedly connected and communicated with the outlet channel and the valve body 1. Since the valve body 1, filter 2, control chamber, inlet channel, outlet channel, cylinder, axial strip guide groove, protrusion, diaphragm, valve stem, main valve flap, auxiliary valve flap and check valve are all mature structures disclosed in the comparative patent, how to quickly start and stop controlling the water flow is also the same as the method disclosed in the comparative patent, which is a technology currently known to those skilled in the art and will not be elaborated here.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the protective device 3 includes a filter cartridge 31 and a water guide box 32. The filter cartridge 31 is rotatably connected to the inside of the valve body 1. The connection between the valve body 1 and the filter 2 is arranged on the inner side of the filter cartridge 31. The water guide box 32 is fixedly connected to the inside of the valve body 1. The filter cartridge 31 is arranged inside the water guide box 32. A water wheel 33 is fixedly connected to the inside of the filter cartridge 31. Two openings of the water guide box 32 are symmetrically arranged above the axis of the water wheel 33. A brush plate 34 in contact with the filter cartridge 31 is fixedly connected to the inside of the water guide box 32. The water guide box 32 can direct the water flow passing through the valve body 1 to impact the water wheel 33 in one direction, so that the water wheel 33 drives the filter cartridge 31 to be cleaned in one direction by the brush plate 34. This can avoid the two sides of the water wheel 33 being subjected to force at the same time, so as to reduce the probability that the rotation of the water wheel 33 is restrained or even stopped, thereby ensuring the smooth flow of the surface of the filter cartridge 31; the top of the brush plate 34 contacts the lowest point of the filter cartridge 31, which can reduce the probability of the impurities brushed off falling back to the surface of the filter cartridge 31, further ensuring the cleanliness of the surface of the filter cartridge 31.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sewage outlet 321 is provided at the bottom of the water guide box 32, and the sewage outlet 321 is arranged below the brush plate 34, which can guide the impurities brushed out of the water guide box 32, and further ensure the cleanliness of the surface of the filter cartridge 31; the sewage outlet 321 is arranged at the lowest point of the inner bottom wall of the water guide box 32, which can reduce the probability of impurities being retained inside the water guide box 32, so as to improve the effective discharge rate of impurities; both ends of the water guide box 32 are fixedly connected and connected with a water guide bucket 35, and the vertical cross-section shape of the water guide bucket 35 is an isosceles trapezoid, which can guide more water into the water guide box 32, so as to improve the rotation cleaning rate of the filter cartridge 31; the interior of the valve body 1 is provided with a sewage outlet 321 connected to the filter cartridge The filter cartridge 31 is rotatably connected to the annular groove 11, and the surface of the filter cartridge 31 is embedded with evenly distributed balls 36 that are slidably connected to the annular groove 11. The balls 36 are annularly distributed around the axis of the filter cartridge 31. The annular groove 11 can lock the filter cartridge 31 more stably inside the valve body 1. At the same time, the balls 36 can reduce the rotational resistance of the filter cartridge 31, further improving the rotational cleaning rate of the filter cartridge 31; the surface of the filter cartridge 31 is fixedly connected with a sealing ring 37 that contacts the annular groove 11, and the sealing ring 37 is arranged on the side of the balls 36 close to the water wheel 33. The sealing ring 37 can prevent impurities in the water flow from entering the annular groove 11, so as to reduce the rotational resistance of the filter cartridge 31.

[0029] When the utility model is in use, when water flows normally through the valve body 1, the water flow is guided to the water guide box 32 through the water guide bucket 35. When the water flow flows inside the water guide box 32, it will impact the filter cartridge 31 and the part above the axis line of the water wheel 33. At this time, one side of the water wheel 33 is subjected to force, and the water wheel 33 can drive the filter cartridge 31 to rotate in one direction, which can avoid that both sides of the water wheel 33 are subjected to force at the same time, so as to reduce the probability of the rotation of the water wheel 33 being restrained or even stopped. When the filter cartridge 31 rotates, it drives the impurities adhered to its surface to rotate together, and the brush plate 34 can brush away the impurities adhered to the surface of the filter cartridge 31, so that the filter cartridge 31 can always be kept clean.
