Abstract
The utility model discloses an anti-reversal liquid filter which comprises a shell, wherein an upper sealing head and a lower sealing head are respectively arranged at two ends of the shell; communicating holes are formed in the upper sealing head and the lower sealing head; a water feeding pipe is connected to the lower sealing head; a filtration joint is arranged on the communicating hole in the upper sealing head; a filtration core is arranged on the filtration joint; a spraying pipe is arranged on the communicating hole in the lower sealing head; an anti-reversal ball is arranged between the spraying pipe and the water feeding pipe; a baffle is arranged at the tail end of the spraying pipe; and a plurality of spraying holes are formed in the side wall of the spraying pipe. The anti-reversal liquid filter is simple in structure, low in cost and convenient to use and can be used for filtering solid substances from liquid; by using a manner of arranging the anti-reversal ball between the water feeding pipe and the spraying pipe, when an external pump does not work or is blocked, water cannot enter the external pump; in order to prevent impurities from falling into the water feeding pipe, the additionally arranged anti-reversal ball can stop the impurities; and the water feeding pipe can be prevented from being blocked.
Description
Technical field
The utility model relates to a kind of filter, specifically refers to a kind of anti-reverse shape liquid filter.
Background technology
Liquid filter is indispensable a kind of device on the pumped (conveying) medium pipeline, is installed in the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for eliminating the impurity in the medium, with the normal use of protection valve and equipment.After entering the filter cylinder that is equipped with the certain specification filter screen when fluid, its impurity is blocked, and the filtrate of cleaning is then discharged by filter outlet, when needs clean, as long as with dismountable filter cylinder taking-up, reloads after the processing and gets final product, and therefore, working service is very convenient.At present use liquid as the equipment of working media in normally by pump with liquid suction control appliance in, control appliance imports liquid in the equipment again.Owing to lack filter in the equipment, the iron filings that cause solid granule in the liquid and equipment easily and deviate from because of wearing and tearing are trapped in control appliance or the equipment, equipment is resulted in blockage, and equipment caused wearing and tearing, make equipment form serious fault and cisco unity malfunction, thereby delayed the normal operation of producing, reduced operating efficiency, therefore bring great economic loss to the user, and, need filtered liquid directly to impinge upon at high speed on the filter core, very easily filter core is caused damage, cause shorten greatly the service life of filter core.
The utility model content
The purpose of this utility model is to overcome at present and directly impinges upon on the filter core at high speed in the needs filtered liquid, very easily filter core is caused damage, cause shorten greatly the service life of filter core, to the defective that equipment results in blockage, provide a kind of anti-reverse shape liquid filter.
The utility model is achieved through the following technical solutions:
A kind of anti-reverse shape liquid filter, comprise housing, be separately installed with upper cover and low head at the two ends of housing, be provided with intercommunicating pore on upper cover and the low head, be connected with water inlet pipe at low head, intercommunicating pore at upper cover is equipped with transition joint, at transition joint filter core is installed, intercommunicating pore at low head is equipped with playpipe, anti-reverse ball is installed between playpipe and water inlet pipe, end on playpipe is equipped with baffle plate, and the sidewall of playpipe is provided with a plurality of spray-holes.The utility model is installed playpipe by the intercommunicating pore at low head; playpipe is as feed pipe; end at feed pipe is installed baffle plate; simultaneously at its sidewall a plurality of spray-holes are set; so; the high-speed liquid that pumps into from feed pipe enters filtering chamber from spray-hole; behind the reduction of speed through filter core, the liquid during reduction of speed, solid residue wherein falls under the gravity effect; further improved the ability of filtering; avoid the direct impact to filter core, effectively protected filter core, improved filter effect; and the service life of filter core; by the mode of anti-reverse ball is installed between water inlet pipe and playpipe; when extraneous pump was not worked or stopped up, water can not enter, and fell into water inlet pipe in order to prevent that impurity from descending; the anti-reverse ball that increases can be finished stopping of impurity, avoids water inlet pipe is resulted in blockage.
Be set with filter at described playpipe, form expansion chamber between filter and the low head.Further, as further improvement of the utility model, by increasing filter, form expansion chamber, solid residue can be collected, avoid it that pipeline and filter core are caused damage.
The seal that low head is provided with dumping pit and is complementary with dumping pit.Further, clear up solid residue for convenience, dumping pit and seal can be set.
Described baffle plate middle part projects upwards the formation arc.Further, the best results of its buffering of baffle plate of arc.
In the intercommunicating pore of low head, be provided with the anti-backflow steel ball.
The utility model compared with prior art has the following advantages and beneficial effect:
A kind of anti-reverse shape liquid filter of 1 the utility model, by the intercommunicating pore at low head playpipe is installed, playpipe is as feed pipe, end at feed pipe is installed baffle plate, simultaneously at its sidewall a plurality of spray-holes are set, so, the high-speed liquid that pumps into from feed pipe enters filtering chamber from spray-hole, behind the reduction of speed through filter core, liquid during reduction of speed, solid residue wherein falls under the gravity effect, has further improved the ability of filtering, and avoids the direct impact to filter core, effectively protected filter core, improved filter effect, and the service life of filter core, by the mode of anti-reverse ball is installed between water inlet pipe and playpipe, when extraneous pump is not worked or stopped up, water can not enter, fall into water inlet pipe in order to prevent that impurity from descending, the anti-reverse ball of increase can be finished stopping of impurity, avoids water inlet pipe is resulted in blockage;
A kind of anti-reverse shape liquid filter of 2 the utility model by increasing filter, forms expansion chamber, solid residue can be collected, and avoids it that pipeline and filter core are caused damage;
A kind of anti-reverse shape liquid filter of 3 the utility model, not only simple in structure, and also with low cost, easy to use.
