Specific embodiment

In conjunction with the description of attached drawing and the application specific embodiment, the details of the application can be clearly understood.But It is the specific embodiment of the application described herein, is only used for explaining the purpose of the application, and cannot understands in any way At being limitation to the application.Under teachings of the present application, technical staff is contemplated that any possible change based on the application Shape, these are regarded as belonging to scope of the present application.

The embodiment of the present application discloses a kind of water route testing agency, including detection channels 1, is arranged in detection channels 1 Detection unit 2, the switching mechanism 3 with filtering water end (W.E.) mouth 4 and raw water port 5, the filtering water end (W.E.) mouth 4 of switching mechanism 3 be used for The filtered water stream road 7 of filter device 29 is connected to, and the raw water port 5 of switching mechanism 3 is used to connect with the raw water runner 6 of filter device 29 It is logical；Switching mechanism 3 is used to control the on-off between detection channels 1 and raw water port 5, and/or, for controlling 1 He of detection channels Filter the on-off between water end (W.E.) mouth 4.

By said mechanism, by the way that switching mechanism 3 is arranged, so that in raw water and can be crossed between drainage in detection channels 1 Switching can also be to filtering so as to can both detect to raw water in the case where detection unit 2 are only arranged Water is detected.

Shown in referring to Fig.1, the embodiment of the present application discloses a kind of water route testing agency, including detection channels 1, setting are being visited Survey the detection unit 2 in channel 1, the switching mechanism 3 with filtering water end (W.E.) mouth 4 and raw water port 5.Wherein, the original of switching mechanism 3 Water end (W.E.) mouth 5 can be connected to the raw water runner 6 of filter device 29, so as to get raw water from raw water runner 6.Switching mechanism 3 filtering water end (W.E.) mouth 4 can be connected to the filtered water stream road 7 of filter device 29, so as to get from filtered water stream road 7 Drainage.

In the present embodiment, detection channels 1 are located at the outside of raw water runner 6 and filtered water stream road 7.Detection channels 1 Entrance (i.e. one of openings 8 of detection channels 1) can be connected to and filter water end (W.E.) mouth 4 with the raw water port 5 of switching mechanism 3 respectively Connection, to accept the raw water separately flowed into from raw water port 5 and filtering water end (W.E.) mouth 4 respectively and cross drainage.

Switching mechanism 3 includes shell, is arranged in the intracorporal piston 21 of shell, a side end face (one of stress of piston 21 Portion 22) it is corresponding with raw water port 5, another side end face (another one forced section 22) is corresponding with filtering water end (W.E.) mouth 4.Work as work When pressure suffered by one side end face of plug 21 is greater than pressure suffered by pressure face suffered by the other side of piston 21, piston 21 under pressure to direction (i.e. towards the direction of filtering water end (W.E.) mouth 4) movement far from raw water port 5, so that raw water Port 5 is connected to detection channels 1, and detection channels 1 and filtering water end (W.E.) mouth 4 disconnect.In this state, can have in detection channels 1 There is raw water, detection unit 2 can detect raw water.The pressure suffered by another side end face of piston 21 is greater than piston 21 A side end face suffered by pressure when, piston 21 under pressure to far from filtering water end (W.E.) mouth 4 direction (i.e. towards raw water The direction of port 5) movement, so that filtering water end (W.E.) mouth 4 is connected to detection channels 1, detection channels 1 and raw water port 5 are disconnected It opens,.In this state, it can have drainage in detection channels 1, detection unit 2 can be detected to drainage is crossed.Based on two Secondary detection as a result, detection unit 2 can detect the service life of filter device 29.

Preferably, the outlet of detection channels 1 is also connected to raw water runner 6, so that the water in detection channels 1 be made to be again introduced into In raw water runner 6, to avoid extra water route is arranged and avoids wasting.

It is highly preferred that being additionally provided with check valve at the outlet (i.e. another opening 8 of detection channels 1) of detection channels 1 9, which can only supply water passes through from the outlet of detection channels 1 to raw water runner 6, certainly to avoid the water in raw water runner 6 The exit of detection channels 1 flows into, to influence the testing result of detection unit 2.

Referring to shown in Fig. 2 and Fig. 3, the embodiment of the present application discloses a kind of water circuit system, which includes last reality Apply the water route testing agency in example, the filter device 29 with raw water inlet 19 and filtering water outlet 20 (such as reverse osmosis membrane apparatus, Nano filter membrance device etc.), the raw water runner 6 that is connected to the raw water inlet 19 of filter device 29, go out with the drainage of crossing of filter device 29 The filtered water stream roads 7 of 20 connection of mouth.In the present embodiment, water circuit system further includes booster pump 23 and elastic mechanism 10.Increase The upstream of the raw water inlet 19 of filter device 29 is arranged in press pump 23.In the present embodiment, booster pump 23 is arranged in raw water stream On road 6, and it is located at along water (flow) direction the upstream of the raw water port 5 of switching mechanism 3.In other optional embodiments, pressurization Pump 23 also can be set in the downstream of switching mechanism 3, that is, be arranged between switching mechanism 3 and filter device 29.Elastic mechanism 10 One end and piston 21 correspond to the end face of filtering water end (W.E.) mouth 4 and connect, the other end of elastic mechanism 10 is connect with shell.
