Summary of the invention
The utility model object is: the proportioning device providing a kind of new structure, and it quantity tube comprised is straight tube shape, easily cleans, easy for removal and installation, only need replace quantity tube during replacing.
The technical solution of the utility model is:
A kind of proportioning device of new structure, comprise housing 11, quantity tube 9 and the quantitative block 4 of photoelectricity be located on quantity tube 9, described housing 11 is hollow structure, described quantity tube 9 is straight tube shape, inside described housing 11, two ends are respectively equipped with packing ring 3, described quantity tube 9 is fixed between two packing rings 3, described packing ring 3 in addition side is also respectively equipped with the upper cover 7 and low head 1 that to flow into through liquid and flow out, described upper cover 7 and low head 1 are each passed through housing 11 two ends, and described upper cover 7 and at least one outer end of low head 1 are arranged with stubborn 6 for being secured to by quantity tube 9 in housing 11.
Further, described upper cover 7 and low head 1 bore are all less than described quantity tube 9 internal diameter.
Further, preferably, fix quantity tube 9 for convenience of packing ring 3, described packing ring 3 is fluted body structure.
Further, for improving the sealing of quantity tube, the washer plate 2 preventing fluid seepage between described quantity tube 9 and packing ring 3, is also provided with.
Further, preferably, described washer plate 2 is rubber washer sheet.
Further, check quantity tube sampling state for convenience, described housing 11 side is provided with transparent windows.
The utility model has the advantages that:
1. the proportioning device of a kind of new structure of the present utility model, by twisting pressure locking end socket, packing ring 3 and the quantity tube 9 of 6, only need turn on 6, can unclamp packing ring 3, and the quantity tube 9 that centre is fixed, and changes, convenient disassembly.
2. quantity tube 9 is straight tubular construction, convenient cleaning.
3. when quantity tube 9 need clean or change, only need change quantity tube 9, other end sockets, packing ring 3 and washer plate 2 etc. still can continue to use, and economize on resources and cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is embodiment quantity tube longitudinal profile structural representation;
Wherein: 1-low head 2-washer plate 3-packing ring 4-photoelectricity quantitative block 5-quantitative block shell 6-twists head 7-upper cover 8-fixed block 9-quantity tube 10-translucent cover 11-housing.
Embodiment
Below in conjunction with concrete drawings and Examples, full and accurate explanation is carried out to the utility model structure.
Embodiment:
A kind of proportioning device of new structure, its structure as shown in Figure 1, comprise the housing 11 of hollow box type structure, be arranged on the packing ring 3 in centre position, two ends inside housing 11, also comprise straight-cylindrical quantity tube 9, which is provided with two groups of quantitative blocks 4 of photoelectricity, quantitative block 4 overcoat has the quantitative block shell 5 of its protection and interception, described quantity tube 9 is fixed between two packing rings 3, described packing ring 3 in addition side is also respectively equipped with the upper cover 1 and low head 7 that to flow into through liquid and flow out, on, low head bore is all less than quantity tube 9 internal diameter, it is each passed through the two ends of housing 11, be convenient to the connection with external connection device, upper cover 7 is arranged with stubborn 6 for being secured to by quantity tube 9 in housing 11, tighten 6 downwards to be made by its pressure, packing ring 3 between low head, mutually lock between quantity tube 9, simultaneously by backing out 6, take end socket and packing ring 3 apart, conveniently can take out quantity tube 9 to carry out changing or cleaning.
Above-mentioned quantity tube 9 can adopt Conventional glass material, and upper and lower end socket can adopt stable chemical nature for increasing the service life, the polytetrafluoroethylmaterial material of heat-and corrosion-resistant function admirable, and housing 11 and packing ring 3 can adopt alumina based material to ensure the stable of its shape and structure.Prevent it from moving for better fixing quantity tube 9 simultaneously, above-mentioned packing ring 3 is designed to groove type packing ring, groove diameter and quantity tube 9 external diameter match, further, fluid seepage when getting liquid for preventing and treating, be provided with elastic washer sheet 2 in packing ring 3 and quantity tube 9 junction, washer plate 2 can be rubber washer sheet, and under certain pressure effect, its anti-seepage effect is better.Further, check sampling state for convenience, housing 11 side is provided with view window, a side translucent cover 10 is taked in this example, simultaneously for ensureing the intensity of housing 11, translucent cover 10 adopts plexiglass tent, and plexiglass tent is by the other partial fixing of fixed block 8 with housing 11.
