Description
Technical field
The point type divided water supply device of the utility model band backwash relates to be a kind ofly be installed on pipeline branch road end, at the device of a local implementation quality classification water supply, be applicable to dwelling house, hotel, small-sized public place quality classification water supply.
Background technology
The water technology of existing small-sized household equipment mainly adopts the hold back formula absorption of all kinds of filter cores to impurity, after impurities accumulation arrives to a certain degree, then need unload lower filter and clean or change, and is cumbersome.
Summary of the invention
The utility model provides a kind of point type divided water supply device with backwash at above-mentioned weak point, can carry out backwash to multi-stage filter core, removes the filter core impurity trapped, guarantees that water quality is pure, easy to operate.
The point type divided water supply device of band backwash takes following scheme to realize: the point type divided water supply device structure of band backwash has the water supply installation housing, three way cock is equipped with on housing top, three way cock has valve gap, valve seat, spool, knob constitutes, three way cock has three close nipples, tap into the mouth of a river respectively, the washings tap, bypass pipe, the housing internal upper part is filled with the preliminary treatment filtrate, the external pressure hollow membrane is equipped with in the bottom, seal the external pressure hollow membrane with the epoxy resin end socket lower end of housing, form pending district and clean water area in the both sides of epoxy resin end socket, at the lower housing portion device through duct is arranged, through duct passes the epoxy resin end socket and is connected with pending district, housing bottom is provided with the bypass pipe connector, the bypass pipe connector is connected with the straight pipe lower water inlet, the bypass pipe upper end links to each other at three way cock bypass pipe interface with device, and end device is at housing bottom bypass pipe connector under the bypass pipe.Housing bottom is provided with the water purification delivery port, and the water purification outlet pipe is housed, and device has clear water faucet on the water purification outlet pipe.
The point type divided water supply device of band backwash is reasonable in design, owing to be provided with three way cock, bypass pipe, straight pipe, can carry out backwash to the impurity that the preliminary treatment filtrate is held back, discharge from the washings tap, overcome the secondary pollution of purifier in the past to filter core because of can not blowdown causing, thereby cleaning in the assurance pretreating zone, guarantee working properly the carrying out of pretreating zone impurity screening, do not need often to unload lower filter, the external pressure hollow membrane cleans or changes, easy to operate, can guarantee the degree of purity of point type divided water supply device clean water area effluent quality, reach drinking water degree of purity standard.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the point type divided water supply device structural representation of band backwash.
Fig. 2 is the three way cock backwash working state schematic representation of the point type divided water supply device of band backwash.
Fig. 3 is the three way cock normal operating conditions schematic diagram of the point type divided water supply device of band backwash.
The specific embodiment
With reference to accompanying drawing 1, the point type divided water supply device structure of band backwash has water supply installation housing 8, three way cock is equipped with on housing 8 tops, three way cock has valve gap 3, valve seat 14, spool 1, knob 2 constitutes, three way cock has three pipe line interfaces, do not tap into the mouth of a river, washings tap 9, bypass pipe 4, housing 8 internal upper parts are filled with pre-reason filtrate 5, external pressure hollow membrane 6 is equipped with in the bottom, seal external pressure hollow membrane 6 with epoxy resin end socket 13 lower end of housing 8, form pending district 11 and clean water area 16 in the both sides of epoxy resin end socket 13, at housing 8 lower devices through duct 7 is arranged, through duct 7 passes epoxy resin end socket 13 and is connected with pending district 11, housing 8 bottoms are provided with bypass pipe connector 15, bypass pipe connector 15 is connected with straight pipe 7 lower water inlets, and bypass pipe 4 upper ends link to each other with the bypass pipe interface of three way cock, and 4 times end devices of bypass pipe are on housing bottom bypass pipe connector 15.Housing 8 bottoms are provided with water purification delivery port 12, and the water purification outlet pipe is housed, and device has clear water faucet 10 on the water purification outlet pipe.
With reference to accompanying drawing 1,2,3, operating principle of the present utility model is described below:
When knob 2 is threaded to spool 1 as shown in Figure 3 state, water enters housing 8 from water inlet through three way cock, and through preliminary treatment filtrate 5, external pressure hollow membrane 6, water after the purification enters clean water area 12 and is discharged by clear water faucet 10, and at this moment the impurity of being held back by external pressure hollow membrane 6, preliminary treatment filtrate resides in pending district 11 and the filtrate 5; When spool 1 is threaded to duty as shown in Figure 2 the time, water passes through spool 1 to by-pass line 4 from water inlet, and process straight pipe 7 is to pending district 11, leading 9 the time when opening washing, the aforementioned impurity of being held back in purification process is discharged by washing tap 9, thereby has reached the purpose of getting rid of impurity in the housing by backwash.
