Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of as shown in drawings newborn film medium plastic draining board 5 vertical water-flowing amount testers are made by stainless steel, mainly comprise ingredient: pressurizing vessel 1, water inlet balanced reservoir 2, water outlet balanced reservoir 3 and manual pressure pump 4.
Pressurizing vessel 1 has two effects, and the one, shelve drain bar 5, two and provide wall pressure.Pressure vessel is welded by the stainless steel cylinder of φ 130, thick 2mm and the ring flange 15 of φ 200, thick 10mm, and effective length is 40cm.Elliptical aperture is opened in the centre of ring flange 15, and port size is 105mm * 10mm (see figure 3), flushes stainless steel supporting plate 6 (see figure 2)s that eye 17 with holes is set with the base, aperture.Arrange tensimeter 7, freeing port 8 (band valve), pressurization mouthful 9 (band valve) (see figure 1) on the pressurizing vessel 1.
Water inlet balanced reservoir 2 high 30cm, horizontal connection tube 18 and ring flange 15 by 150mm * 40mm are welded into integral body.The perforate of ring flange is with the ring flange unanimity of pressure vessel.At water tank inside bottom place vertical inlet mouth 10 (see figure 1)s are set.The overflow bank 11 of high 25cm (bottom surface with water tank is a basic point) together is set in the water tank, and the high 16cm place, the outside of water inlet balanced reservoir 2 is provided with horizontal gap 12 (see figure 1)s.
Water outlet balanced reservoir 3 height are 7cm, and the horizontal connection tube 18 by 150mm * 40mm is welded into integral body with ring flange 15.The perforate of ring flange is with the ring flange unanimity of pressure vessel.The overflow bank 13 of high 5cm (bottom surface with water tank is a basic point) together is set, horizontal gap 14 (see figure 1)s of the arranged outside of overflow balanced reservoir in the water tank.
4 one of manual pressure pumps, rated pressure are 2.5Mpa; 16 4 of rubber blankets, thick 1cm is of a size of 150mm * 40mm, and middle perforate is of a size of 105mm * 6mm (see figure 4); Tubulose latex film 19 thick 0.25mm, length and width are of a size of 550mm * 100mm; Drain bar 5 packoffs are seen Fig. 5.
The precision of equipment is: the precision of tensimeter 7 is 1.6%FS; The effective length precision is 400 ± 4mm; The precision of head difference is 200 ± 2mm.
The test operation step is as follows:
1) sample is installed
Plastic draining board 5 is cut into the long sample of about 48cm, and the filter membrane at two is respectively removed 1cm, and chamfering at 45 is cut at 4 angles of drain bar 5 core bands, and in the tubulose latex film of packing into carefully.
