Technical field
The utility model relates to the mensuration of water quality.Especially for the routine test of water quality, promptly to characterizing the test of pre-service water outlet colloidal content.
Background technology
The duct type water pollution index tester of prior art, mainly form by pipe adapter, valve, voltage stabilizer, tensimeter and filtrator, the filtrator that inserts and puts filter membrane adopts three screws of tripartite confrontation to regulate, use inconvenient, because intuitive is poor, relief port is not set yet, and bubble is difficult for eliminating, and certainly will cause the dispersion of test data to increase.
Technology contents
The utility model is intended to propose the problem that improved technical scheme solves above-mentioned existence.
Duct type water pollution index tester of the present utility model, comprise pipe adapter, valve, voltage stabilizer, tensimeter and filtrator, it is characterized in that said filtrator is covered by pop-up lid, subiculum and the attaching nut forms, interlaced fastening and formation chamber between the holder lid, filter membrane, porous supporting plate are set in the chamber, porous supporting plate outward flange is established O-ring seal, filter membrane is clamped between the supporting plate, the attaching nut is threaded with being connected to of holder lid, and said pop-up covers the air release that is provided with an interior cavity chamber.
Be provided with hydraulic quick coupler between described filtrator and the tensimeter.
Good effect of the present utility model is:
1, the fastening structure ratio that adopts screw thread to screw is convenient with the fixing means of three screws.
2, adopt hydraulic quick coupler, be convenient to unload filtrator and clean, assemble, also be convenient to Fast Installation.
When 3, particularly adopting transparent material to make outer casing member, the duty and the air release that can observe directly filter membrane cooperate, and eliminate bubble and influence that the filter membrane surface may exist.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the filter structure schematic representation of band hydraulic quick coupler.
Fig. 3 is the prior art constructions synoptic diagram.
Embodiment
Be illustrated below in conjunction with drawings and Examples:
As shown in Figure 1, 2, duct type water pollution index tester comprises pipe adapter 5, adapter 6, valve 4, voltage stabilizer 7, tensimeter 3 and filtrator 1,9th, faucet.Its middle filtrator 1 is made up of pop-up lid 17, subiculum lid 20 and attaching nut 19 thereof, holder covers and is provided with the convex tendon of strengthening usefulness, interlaced fastening between the holder lid, prevent circumferential rotation, and formation chamber, the porous supporting plate 21,23 that filter membrane is used is set in the chamber, and porous supporting plate 23 outward flanges are provided with the O-ring seal 18 of " O " type.Filter membrane 22 is clamped between the porous supporting plate and effectively seals by O-ring seal 18, and attaching nut 19 is threaded with being connected to of subiculum lid 20, and the pop-up lid 17 of said filtrator 1 is provided with the air release 8 of an interior cavity chamber; Be provided with hydraulic quick coupler 2 between filtrator 1 and the voltage stabilizer 7.
Fig. 2 is the partial structurtes detail drawing of Fig. 1, is disposed with :-→ be connected on the connector 10 on the voltage stabilizer 7---taper stage clip 11---slide post piece 26---fixed cover 12---O-ring seal 13-steel ball 14---cylindrical spring 15---cutting ferrule 16---attachment plug 24---pop-up lid 17---porous supporting plate 23---O-ring seal 18---filter membrane 22---porous supporting plate 21---attaching nut 19---subiculum lid 20---faucet 9-→
Hydraulic quick coupler is divided into two parts, and its Connection Block is made up of connector 10, slide post piece 26, fixed cover 12, cutting ferrule 16, is connected with voltage stabilizer by connector 10, and attachment plug 24 is connected with the pop-up lid 17 of filtrator.When Connection Block was inserted in attachment plug 24, steel ball fell into the traverse furrow of attachment plug 24, and cutting ferrule 16 moves forward under the effect of cylindrical spring 15 simultaneously, and its internal projection is pushed down steel ball, and plug can't be thrown off; Slide post piece 26 reach is withstood in attachment plug on the other hand, makes limbers 25 on the slide post piece 26 be positioned at the upside of O-ring seal 13, forms water stream channel, makes the filter membrane chamber diffluence of water toward filtrator.When throwing off Connection Block, must will move on the cutting ferrule 16 with the hand application of force, under the effect of volute spring 11, steel ball comes off from the traverse furrow of plug and enters in the groove in the cutting ferrule, and compression cylindrical spring 15 also is in a Room, and attachment plug unlocks, deviate from the slide post block reset thereupon.Behind the slide post block reset, top limbers 25 is displaced downwardly to the downside of O-ring seal 13, the sealed circle blocking-up of water stream channel, and water is closed automatically.
The physical contamination of water quality adopts pollution index FI (also claiming SDI) to estimate traditionally, is determined under the constant voltage of 0.21Mpa to carry out, and tested water is the CN-CA of 0.45 μ m by diameter phi 47mm, aperture, and record is initial by the required time t of 500ml water
1, continuing water flowing 15 minutes (T) then, record is by the required time t of 500ml water again
2, calculate according to following formula: FI=(1-t
1/ t
2) 100/15
The course of work of measuring is as follows:
1, installs by Fig. 1, pressure is adjusted to 0.21MPa
2, filtrator is thrown off from hydraulic quick coupler, unload the subiculum lid, cleaning is loaded onto the filter membrane (claiming filter paper sometimes) that has soaked into and filtrator is installed onto on the hydraulic quick coupler again;
3, open the upper end ball valve, allow tested current, enter filtrator, can be observed the situation that current arrive filter membrane, open the air release of filtrator, allow bubble discharge through voltage stabilizer, hydraulic quick coupler;
4, t is kept in official testing in mind
1, t
2, T;
5, calculate the FI value.
After the test, close ball valve, take off filtrator and take out filter membrane, filtrator is rinsed well standby.
Prior art infrastructure product shown in Figure 3 is thing from abroad, is followed successively by the pop-up lid-round section joint ring-filter membrane-porous supporting plate-subiculum lid-faucet of pipe adapter-transfer tube-ball valve-tensimeter-voltage stabilizer-filtrator from top to bottom.Being used to connect what regulate the upper and lower supporter lid is the screw that three tripartite confrontations distribute.Filtrator is opaque, fixes, exists when regulating certain blindness.
