Abstract
The utility model relates to a check valve, in particular to a duckbilled rubber check valve which can be arranged on the end of pipelines and used for city blood draining, heavy rain discharging, and coastal discharging, and has the check control effect. The duckbilled rubber check valve of the utility model comprises a rubber tube, and one end of the rubber tube is provided with a water inlet tap, and the other end of the rubber tube is compressed into flat that is the duckbilled water outlet. One side of the duckbilled water outlet is provided with a steel sheet, and the other side is provided with a magnet. The steel sheet and the magnet are in attraction status. The utility model is of total rubber structure, which meets various demands of anticorrosion. The utility model has the advantages of non-blocking, good sealing, long life-span, without fault and repair, free of electric signal and manual operation, no noise, convenient installation, lower expense, and lower operating cost.
Description
Technical field
The utility model is a kind of end of line that is installed in, and is used for effluent discharge, and drain off floodwaters in the city, heavy rain discharges, coastal discharging, and can play the safety check of non-return effect, particularly a kind of duck-beak type rubber safety check.
Background technique
The safety check that is used for effluent discharge of the prior art, complex structure is installed inconvenience, needs often maintenance, so influenced using effect.
Summary of the invention
The purpose of this utility model is the duck-beak type rubber safety check of a kind of long service life of invention, fault-free, the full rubber structure of freedom from repairs.
The utility model is realized as follows: duck-beak type rubber safety check described in the utility model, comprise a rubber pipe, one end of this rubber pipe is provided with water supply connector, this rubber pipe the other end is compressed to flat, constitute the duck-beak type water outlet, one side of duck-beak type water outlet is provided with steel disc, and opposite side is provided with magnet, and steel disc and magnet are in attracting state.
Described steel disc and magnet are elastomer.
Described steel disc is that a plurality of steel disc word orders form, and described magnet is that a plurality of magnet word orders form.
The utility model has following good effect:
1. the utility model is full rubber structure, can satisfy various requirements for anticorrosion (according to the actual requirements, can select different rubber materials);
2. do not stop up, good seal;
3. long service life, fault-free, freedom from repairs.
4. need not electrical signal and manual operation, noise free.
5. cracking pressure is little, just can open greater than 0.01 meter head.
6. under the general condition, loss of head can drop to minimum degree.
7. can conversion various installation forms, to satisfy client's needs.
8. it is convenient to install, and expense is low, and operating cost is little.
Description of drawings
Fig. 1 is the utility model structural drawing
Among the figure: 1 rubber pipe, 2 water supply connectors, 3 water outlets
4 steel discs, 5 magnet
Embodiment
As shown in Figure 1, duck-beak type rubber safety check described in the utility model, comprise a rubber pipe 1, one end of this rubber pipe 1 is provided with water supply connector 2, this rubber pipe 1 the other end is compressed to flat, constitutes duck-beak type water outlet 3, and a side of duck-beak type water outlet 3 is provided with steel disc 4, opposite side is provided with magnet 5, and steel disc 4 is in attracting state with magnet 5.
Described steel disc 4 and magnet 5 are elastomer.
Described steel disc 4 forms for a plurality of steel disc word orders, and described magnet 5 forms for a plurality of magnet word orders.
During use, earlier the water supply connector 2 of this safety check is docked with the water outlet 3 of drain pipe, because the steel disc 4 of duck-beak type water outlet is inhaled mutually with magnet 5, duckbilled is airtight, the interior sewage of pipe can not be discharged, and when the pressure of sewage in the pipe during greater than the suction of steel disc 4 and magnet 5, duckbilled is opened, and begins blowdown at this moment.The utility model cracking pressure is little, just can open valve when common forward and reverse water-head surpasses 10mm, and loss of head is minimum.When flood arrived, safety check was inundated with flood, when the pressure of safety check outside flood greater than pipe in during sewage pressure, the pressure of flood will force steel disc to be inhaled mutually with magnet, duckbilled is closed automatically, and flood can not blowed back in the safety check.Usually in the dark water of 2m, do not have the leakage of rushing down substantially, but in the dark water of 10m valve proper functioning still.Because under certain high temperature and under the time, rubber can wear out after all, the elastic rubber of water outlet weakens, can lose the effect of safety check, in water outlet rubber on one side, put certain magnet now, another side is put certain guiding principle bar, can also reach certain non-return effect like this when ageing of rubber.
