The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 5, the water sample filter of the utility model one embodiment, comprising: a lower cover 10, a upper cover body 20, a filter paper 30, one first sealing ring 40 and one second sealing ring 50 form.
Wherein, consult shown in Fig. 1 and Fig. 2, the central area of this lower cover 10 is provided with the filter paper fixed part 103 that is interspersed and is formed by a plurality of arc bumps 1031 and groove 1032, this lower cover 10 center is provided with and connects the outlet conduit 104 connecting, the end of this outlet conduit 104 is provided with pipe joint 1041, the outer ring of this filter paper fixed part 103 is provided with the first sealing ring placement section 101 of ring-type, and the outer ring of this first sealing ring placement section 101 is provided with the second sealing ring placement section 102 of ring-type.
Preferably, also comprise one first bulge loop 1051 on this lower cover 10, this first bulge loop 1051 is arranged at the outer ring of this filter paper fixed part 103, thereby the inner circle area of this first bulge loop 1051 forms this first sealing ring placement section 101; And on this lower cover 10, also comprise one second bulge loop 1052, this second bulge loop 1052 is arranged at the outer ring of this first bulge loop 1051, thus this first bulge loop 1051 and this second bulge loop 1052 between region form this second sealing ring placement section 102.
Wherein, consult shown in Fig. 3 and Fig. 4, this upper cover body 20 center is provided with and connects the inlet channel 203 connecting, the end of this inlet channel 203 is provided with pipe joint 2031, the corresponding position of the first sealing ring placement section 101 of this upper cover body 20 and this lower cover 10 is provided with the first sealing ring contact part 201 of ring-type, and the corresponding position of the second sealing ring placement section 102 of this upper cover body 20 and this lower cover 10 is provided with the second sealing ring contact part 202 of ring-type; Preferably, this first sealing ring contact part 201 of this upper cover body 20 is a bulge loop, first sealing ring 40 of can more closely conflicting.
Wherein, this filter paper 30 is positioned on this filter paper fixed part 103 of this lower cover 10, for water sample is filtered.This first sealing ring 40 is positioned over the first sealing ring placement section 101 of this lower cover 10 and is closely conflicted by the first sealing ring contact part 201 of this upper cover body 20; Thereby the edge of this filter paper 30 is firmly mortgaged and is realized to the sealing of water sample.This second sealing ring 50 is positioned over the second sealing ring placement section 102 of this lower cover 10 and is closely conflicted by the second sealing ring contact part 202 of this upper cover body 20, thereby realize, aeroseal is carried out in these filter paper 30 peripheries.This upper cover body 20 is covered on this lower cover 10 fixing, and preferably this lower cover 10 is provided with external screw thread (do not omit and do not draw in figure), and this upper cover body 20 is provided with internal thread (do not omit and do not draw in figure), and this upper cover body 20 is threaded connection fixing with this lower cover 10.
In addition, this lower cover 10 of the water sample filter of this embodiment and this upper cover body 20 can adopt transparent acrylic to make, so that filtration situation and abnormality that can clear view reagent.
The water sample filter of this embodiment of the utility model, the pipe joint of upper cover body 20 2031 is connected in to the water inlet end of water sample pipeline, the pipe joint of lower cover 10 1041 is connected in to the water side of water sample pipeline, when the water body of water sample pipeline passes through inlet channel 203 inflows of upper cover body 20, by this filter paper 30, carried out contaminant filter, by the first sealing ring 40 of these filter paper 30 peripheries, realizing water body seals, and 50 pairs of peripheral air of the second sealing ring of these the first sealing ring 40 peripheries are carried out air seal, thereby realized dual-seal, the outlet conduit 104 of this lower cover 10 of water sample after filtering via filter paper 30 flows out.Because the water body of water sample pipeline is under the extraction pressure of water pump, must produce pressure to the filter paper 30 of this water sample filter, and the filter paper fixed part 103 of this water sample filter is designed to the structure that is interspersed and is formed by a plurality of arc bumps 1031 and groove 1032, can produce planar support effect and not affect water body flow filter paper 30, thereby this water sample filter can be used more for a long time, reduce the frequency of changing filter paper.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
