The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof that foundation this utility model is provided, describe in detail as after.
As shown in Figure 1, a kind of liquid feed device of multiplexing machine comprises hydraulic pump 1, and wherein, a water feed apparatus 2 has a water inlet switch 21 and an air relief valve 22, and air relief valve is contained in connects the port that returns infiltration;
The outfan 21-1 of described water feed apparatus 2 is by 6-1-1 and 6-1-2 port in parallel configuration measuring cup liquid emptying control valve 3 and the disinfectant solution control valve 4 of liquor charging pipeline by three-way connector 6-1; Connect an intake pressure adjusting device 5 at one of the connector of disinfectant solution control valve 4 outfan 4-1 by the liquor charging pipeline along the liquor charging pipeline, described intake pressure adjusting device is to connect the one group of first check valve 7-1 parallel with one another and the second check valve 7-2 by three-way connector 6-2,6-3,6-4 on this liquor charging pipeline, and this second check valve 7-2 and aforesaid hydraulic pump are connected in parallel;
Output port by three-way connector 6-5 between first check valve and second check valve is provided with air relief valve 8 by the liquor charging pipeline, and two outfans of this air relief valve are first supply opening 8-1 and overfall 8-2; Described first supply opening 8-1 disposes the first delivery port 6-6-1 and the second delivery port 6-6-2 that leads to the inside and outside film feed pathway of filter by three-way connector 6-6, with the inside and outside film of supply washing and filtering device.
Operation principle:
When carrying out disinfection operation, open disinfectant solution control valve 4, hydraulic pump pumping disinfectant solution enters multiplexing machine and filter; During the operation of emptying measuring cup, open measuring cup liquid emptying control valve 3, open feed liquor valve and drain valve (known techniques is expression) in the film in the multiplexing machine simultaneously, hydraulic pump works makes the liquid emptying in the measuring cup, to enter next step operation.
Opening water inlet switch 21 returns infiltration and enters multiplexing machine; (flow is about 1.5L/min when intake pressure meets default washing and filtering device hydraulic pressure value, hydraulic pressure is the standard normal pressure) time, hydraulic pump 1 is in closed condition, returning infiltration by two check valves parallel with one another outputs, and the output port by three-way connector 6-6 enters filter and washes inside and outside film;
When intake pressure is higher than default washing and filtering device hydraulic pressure value, hydraulic pump still is in closed condition, return infiltration by two check valve outputs parallel with one another, this moment, the overfall of outfan air relief valve was opened, water under high pressure is drained, and enters filter through the output port of the satisfactory water in decompression back by three-way connector 6-6 and washes inside and outside film;
When intake pressure is lower than default washing and filtering device hydraulic pressure value, hydraulic pump is in opening, check valve 7-1,7-2 have stoped the liquid stream loop of this pipeline, water by three-way connector 6-2 dirty terminal 6-2-1 and the dirty terminal 6-3-1 of three-way connector 6-3 is descending enters filter by pipeline via the outfan of three-way connector by the hydraulic pump pressurization and wash its inside and outside film; Even the water of hydraulic pump pumping is up via three-way connector 6-4 or 6-5, also can keep off when the check valve, the output port 6-6-1 by three-way connector 6-6 sends;
When pumping hydraulic pressure was too high, the overfall of outfan air relief valve was opened, and water under high pressure is output, and the satisfactory reverse osmosis water of process decompression enters the path that filter leads to inside and outside film by the output port of three-way connector 6-6, inside and outside the flushing membrane.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
