Abstract
The utility model provides a demounting-free and washing-free filtering device for a liquid supply pipeline system. The device is composed of a three-way pipe fitting (1), a tubular filter screen (2), a liquid inlet pipe (3), a valve (4), a blow-off pipe (5) and a liquid purifying pipe (6), wherein the liquid inlet pipe (3) is in threaded connection with the horizontal inlet of the three-way pipe fitting (1), while the valve (4) is in threaded connection with the horizontal outlet thereof; the tubular filter screen (2) is embedded between the liquid inlet pipe (3) and the valve (4); the blow-off pipe is in threaded connection with the outlet of the valve; and the liquid purifying pipe (6) is in threaded connection with the vertical outlet of the three-way pipe fitting (1). The demounting-free and washing-free filtering device can be used for avoiding the troubles of demounting and washing, and replacing the common filtering device after being blocked by pollutants, and also preventing influence on normal operation of the liquid supply system caused by demounting and washing the filtering device; therefore, the service life of the filtering device is guaranteed. As a result, the filtering effect and the working efficiency are improved.
Description
Technical field the utility model relate to a kind of utilize liquid avoid the liquid feeding pipeline filter of frequent disassembly, cleaning and replacing from flushing action.
Background technology is in the feed liquid pipeline system for certain purpose, for the liquid cleaning that guarantees to carry does not contain dirt, in the pipe-line system of being everlasting, filter is installed, because the choking phenomenon of the dirt under the filter happens occasionally, is made filter often disassembly, cleaning or replacing.Disassembly, cleaning or Renewal process have not only affected the normal operation of pipe-line system, have also increased the cost of filter service and replacing simultaneously.
Summary of the invention the purpose of this invention is to provide a kind of disassembly, cleaning that need not, utilize the flushing action of liquid self dirt under remove filtering, make pipe-line system remain unimpeded sedimeter, this device has remedied the technical deficiency that existing filter affects the normal operation of pipe-line system because of disassembly, cleaning and increases replacement cost.
The feature of this device is to be combined by tee pipe fitting, tubular screen pack, feed tube, valve, blow-off pipe and clean liquid pipe, its assemblage characteristic is with the feed tube that has been threaded at the horizontal access place of tee pipe fitting, at the Horizontal Exit place with the valve that has been threaded, between feed tube and valve, be embedded with the tubular screen pack, the exit of valve is with the blow-off pipe that has been threaded, and the vertical outlet place of tee pipe fitting is with the clean liquid pipe that has been threaded.
Basic technical scheme of the present utility model is: with tubular screen pack of setting-in in the tee pipe fitting, the liquid that flows out through the threeway vertical outlet is filtered; Another Horizontal Exit place of this tee pipe fitting is installed valve.The filter that formation can utilize the liquid of carrying to wash voluntarily.
Under normal feed status, valve is in closed condition.Liquid is entered by the horizontal access of tee pipe fitting, and the vertical outlet from tee pipe fitting after filtering by the tubular screen pack flows out, and will be trapped within on the tubular screen pack if any dirt.
The dirt of holding back on the tubular screen pack increases, and when the pipeline pressure augmented flow reduces, opens in short-term the valve of tee pipe fitting Horizontal Exit end, utilizes the flushing action of liquid itself that the dirt on the tubular screen pack is gone out.
When the dirt that filters is rinsed well, when pipeline pressure reduced flow and increases, valve-off, liquid filtered through the tubular screen pack again and flow out by the tee pipe fitting vertical outlet.The open and close of valve can realize automatically control according to pressure and the flow of pipe-line system.
The beneficial effects of the utility model are: on the one hand, avoided because the trouble of filter disassembly, cleaning and the cost of replacing; On the other hand, guarantee running without interruption of induction system, increase work efficiency.
Following three width of cloth charts of description of drawings understand basic summary of the invention of the present utility model and operation principle.
Fig. 1 structure principle chart of the present utility model
Fig. 2 filtration condition figure of the present utility model
Fig. 3 cleaning state diagram of the present utility model
Each number in the figure is respectively: 1, tee pipe fitting; 2, tubular screen pack; 3, feed tube; 4, valve; 5, blow-off pipe; 6, clean liquid pipe.
The specific embodiment as shown in Figure 1, principal character has tee pipe fitting (1), tubular screen pack (2), feed tube (3), valve (4), blow-off pipe (5) and clean liquid pipe (6) in the utility model implementation process.
Installation of the present utility model is closed: at the horizontal access place of tee pipe fitting (1) with the feed tube that has been threaded (3), at the Horizontal Exit place with the valve that has been threaded (4), between feed tube (3) and valve (4), be embedded with tubular screen pack (2), the exit of valve is with the blow-off pipe that has been threaded, and the vertical outlet place of tee pipe fitting (1) is with the clean liquid pipe (6) that has been threaded.
Above-mentioned 1～6 parts have formed the liquid collecting body and have filtered, certainly washed the liquid feeding pipeline system filter in one.This filter can design and produce according to different size.Valve in the filter (4) can be elected autocontrol valve as, automatically opens or closes according to flow and the pressure of pipe-line system.
Claims (1)
- One kind be used for the liquid feeding pipeline system exempt to unpick and wash the formula filter, it is characterized in that by tee pipe fitting (1), tubular screen pack (2), feed tube (3), valve (4), blow-off pipe (5) and clean liquid pipe (6) combine, its assemblage characteristic is with the feed tube that has been threaded (3) at the horizontal access place of tee pipe fitting (1), at the Horizontal Exit place with the valve that has been threaded (4), between feed tube (3) and valve (4), be embedded with tubular screen pack (2), the exit of valve is with the blow-off pipe that has been threaded, and the vertical outlet place of tee pipe fitting (1) is with the clean liquid pipe (6) that has been threaded.
