Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1-3, the embodiment provides a water valve with secondary filtration, which comprises a valve body 100, a primary filter 110 is disposed at the bottom of the valve body 100, a secondary filter 120 is disposed at the side of the valve body 100, the secondary filter 120 is connected to the primary filter 110 through a pipeline, when water mixed with impurities enters the valve body 100, the water is firstly filtered through the primary filter 110 to filter impurities with larger particles, and the water after primary filtration enters the secondary filter 120 through a pipeline, because the secondary filter 120 contains a double-layer filter screen 130, the double-layer filter screen 130 can filter impurities with larger particles and can also filter silt and microorganisms, wherein the double-layer filter screen 130 comprises a first filter screen 131 which is horizontally disposed and a second filter screen 132 which protrudes to the top and is arc-surface shaped, and the water flow is firstly filtered through the first planar filter screen 131, and finally, the underground water or the river water is further filtered by a second arc-shaped filter screen 132, and the underground water or the river water is filtered twice by the first-stage filter 110 and the second-stage filter 120, so that the water quality can reach a clean degree.
Preferably, secondary filter 120 still includes base 121, top cap 122 embolias from base 121 top, both pass through threaded connection, and both connect the back, secondary filter 120's inside is formed with holding chamber 123, double-deck filter screen 130 is then installed in this holding chamber 123, specifically set up in the space of reserving between base 121 top and top cap 122 inner wall, when needs dismantle double-deck filter screen 130 and wash, only need upwards screw out top cap 122, this double-deck filter screen 130 just sets up the top at base 121, consequently, can directly take out double-deck filter screen 130, it is very convenient to dismantle.
Preferably, the upper and lower both sides of double-deck filter screen 130 are equipped with sealed pad 140 respectively, prevent to get into the water in the secondary filter 120, pass through in the space between double-deck filter screen 130 side and top cap 122, have improved sealing performance, simultaneously, the tip of first filter screen 131 and second filter screen 132 is fixed through fixed block 150 simultaneously sealed between the pad 140, when water is passing through double-deck filter screen 130, rivers can produce certain impact force to double-deck filter screen 130, through fixing double-deck filter screen 130 on fixed block 150, can improve the ability of double-deck filter screen 130 water impact resistance, avoid when the more urgent condition of rivers that get into secondary filter 120, with the condition that double-deck filter screen 130 washed away, improved double-deck filter screen 130's water impact resistance ability, and then improved the whole job stabilization nature of secondary filter 120.
Preferably, the middle of the top end of the top cover 122 and the middle of the bottom end of the base 121 are respectively provided with a through hole 124, the through holes 124 of the top cover and the bottom end of the base 121 are located on the same axis, so that the secondary filter 120 is communicated up and down in the axis direction of the middle, the groundwater or river water enters from the through hole 124 at the bottom of the secondary filter 120 through a pipeline after being filtered by the primary filter 110, then flows out from the through hole 124 at the top of the secondary filter 120 after being filtered by the two layers of filter screens, and enters the electromagnetic control valve 160 arranged at the top of the valve body 100 through a pipeline, at this time, because the water has reached a clean degree after passing through the primary filter 110 and the secondary filter 120, after entering the electromagnetic control valve 160, the diameter of only a few impurities in the water flow is smaller than the gap between the iron core and the guide sleeve inside the electromagnetic control valve 160, and, and meanwhile, the cost required for replacing parts is saved.
In addition, the secondary filter 120 is fixed on the edge of the electromagnetic control valve 160 through an iron sheet, if the situation that the valve cannot work normally is met, the internal part of the secondary filter 120 is blocked, at the moment, only the top cover 122 needs to be screwed, the double-layer filter screen 130 is taken out and cleaned by clean water, normal work can be continued after the secondary filter is re-installed, and the whole assembly and disassembly are very convenient.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the technical means, but also comprises the technical scheme formed by the arbitrary combination of the technical characteristics. The above is a detailed implementation manner of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
