As preferably, the upper end of described filter body is provided with end cover.Can safeguard convenient to overhauling in the filter body, clearing up after end cover is opened.
As preferably, described water inlet also is provided with screen pack.The screen pack of water inlet plays the effect of preliminary filtration, and the screen pack at delivery port place plays the effect of secondary filter, thereby guarantees filter effect preferably.
As preferably, filter body, water inlet pipe and outlet pipe adopt the UPVC material to make.The product that the UPVC material is made has corrosion resistance, fluid resistance is little, the mechanical strength height, health is nontoxic, quality is light, easy for installation, plurality of advantages such as good seal performance, and filter body, water inlet pipe and the outlet pipe made with the UPVC material have These characteristics, so easy for installation, the good seal performance of this kind gravity rain water drainage strainer, long service life.
As preferably, the lower end of described taper mudhole is connected with blow-off pipe.Blow-off pipe to early stage rainwater and impurity etc. play the effect of a water conservancy diversion, be convenient to collect, prevent early-stage rainwater and impurity sinuous flow everywhere, environment is caused secondary pollution.
Therefore, the utlity model has simple in structurely, make, maintenance cost is low, the beneficial effect of long service life.
Description of drawings
Fig. 1 is the view when the utility model initial stage, rainwater flowed in a small amount.
The view of Fig. 2 when to be that the utility model is normal collect a large amount of rainwater.
Among the figure: 5 times filter chambers of filter chamber, 6 water inlets, 7 delivery ports, 8 baffle plates, 9 screen packs, 10 taper mudholes, 11 springs, 12 heavy ball 13 end covers 14 blow-off pipes 15 on filter body 1 water inlet pipe 2 outlet pipes 3 diaphragms 4
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of gravity rain water drainage strainer as shown in Figure 1, comprise filter body 1, be provided with filter chamber in the filter body 1, left side, filter body 1 upper end is provided with water inlet pipe 2, water inlet pipe 2 is connected with the end of rainwater manifold trunk, right side, filter body 1 upper end is provided with outlet pipe 3, middle part in the filter chamber laterally is provided with diaphragm 4, diaphragm 4 is separated into filter chamber 5 and following filter chamber 6 to filter chamber, water inlet pipe 2 is communicated with last filter chamber 5, be provided with water inlet 7 between the left end of diaphragm 4 and the filter body 1, the water inlet is provided with screen pack, be provided with delivery port 8 between the right-hand member of diaphragm 4 and the filter body 1, the delivery port place also is provided with screen pack, screen pack in the present embodiment is metal filter screen, metal filter screen has the characteristics of long service life, be provided with the baffle plate 9 of separating water inlet 7 and delivery port 8 in the last filter chamber 5, baffle plate 9 can prevent that rainwater from directly flowing out from outlet pipe after water inlet pipe enters filter chamber, the bottom of following filter chamber 6 is provided with vertical taper mudhole 11, the lower end of taper mudhole 11 is connected with blow-off pipe 15, the taper mudhole big footpath opening up, be positioned on the downside of diaphragm 4 the taper mudhole directly over be hung with spring 12, the lower end of spring 12 is hung with heavy ball 13, the upper end of filter body 1 is provided with end cover 14, heavy ball stretches in the taper mudhole, under the nature, heavy ball does not contact with the hole wall of taper mudhole, thereby make filter chamber down be communicated with the external world with gap between the heavy ball by the taper mudhole, heavy ball and taper mudhole are formed a simple and easy pressure valve, under the nature, simple and easy pressure valve is in normally open, when being under pressure, the upper end of heavy ball does the time spent, the hole wall of the surface of heavy ball and taper mudhole fits tightly sealing, and this moment, simple and easy pressure valve was in closure state.Rainy day, mixing a large amount of dust in a small amount of rainwater at initial stage, various pollutions such as the grains of sand, with serious pollution initial stage a small amount of rainwater is introduced into filter chamber from water inlet pipe, shown in the arrow among Fig. 1, filter chamber under flowing to from the water inlet under the gravity effect then, because the amount of rainwater is very little, pressure effect to heavy ball is also little, can't overcome the pulling force of spring, therefore there is the gap between the hole wall of heavy ball and taper mudhole, simple and easy pressure valve still is in open mode, the initial stage in a small amount rainwater flow into discharge filter body behind the blow-off pipe from the taper mudhole, realize rain water drainage.In the present embodiment, filter body 1, water inlet pipe 2 and outlet pipe 3 adopt the UPVC material to make in light weight, easy for installation, the good seal performance of this kind gravity rain water drainage strainer, long service life.
As shown in Figure 2, when rainfall is bigger, a large amount of rainwater enter in the filter chamber 5 from water inlet pipe 2, under the gravity effect, rainwater enters down in the filter chamber 6 from water inlet 7, this moment under the effect of screen pack through once tentatively filtering, because amount of rainfall is bigger, under the gravity effect, the upper side that rainwater impacts at heavy ball 13 produces bigger pressure, the pressure effect makes spring 12 elongate, the hole wall of the surface of heavy ball 13 and taper mudhole 11 fits tightly sealing, and this moment, simple and easy pressure valve was in closure state, along with the continuous inflow of rainwater in the following filter chamber, rainwater is forced to flow to delivery port 8, carry out secondary filter at the screen pack place when rainwater flows through delivery port 8, and discharge from outlet pipe 3, thereby realize dmp filter, shown in the arrow among Fig. 2, the flow direction of expression rainwater.After the filtration of delivery port place, a lot of impurity all are stored in down in the filter chamber, after rain stops, enter down the water yields in the filter chamber 6 and reduce until stopping, the pressure on the heavy ball is laid down, heavy ball 13 rises under the pulling force effect of spring 12 and resets, simple and easy pressure valve is in open mode, and when Sometimes When It Rains, the impurity in the following filter chamber 6 can discharge from the taper mudhole along with initial stage a small amount of rainwater next time, thereby realize the impurity effect of cleaning automatically, do not need blowdown manually.Therefore, this kind gravity rain water drainage strainer has simple in structure, makes, maintenance cost is low, the beneficial effect of long service life.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
