Abstract
The utility model belongs to the field of valves, and particularly relates to a double-filter-screen water pump bottom valve. The double-filter-screen water pump bottom valve comprises a valve body, filter screens, bolts, a valve element, sealing rings and a guiding ring; the valve body and the filter screens are connected through the bolts, the valve element is located in the valve body, one end of the valve element is located in the guiding ring, the other end of the valve element is adjacent to the sealing rings, and the sealing rings are located between the filter screens and the valve body. The double-filter-screen water pump bottom valve is characterized by further comprising filter screen covers; the surfaces of the filter screens are in blade point shapes, and the filter screen covers are located outside the filter screens to be fixedly connected with the filter screens and the valve body through the bolts. By means of the double-filter-screen water pump bottom valve, blocked sundries are crushed into small fractions under the effect of suction force of a water pump, the blocking problem is accordingly solved, the filter screen covers are convenient to disassemble and simple in structure, and the effect of protecting the filter screens is achieved.
Description
Technical field
The utility model belongs to valve field, relates in particular to a kind of bottom valve of water pump.
Background technique
Bottom valve of water pump is arranged on the bottom of suction pipe under water, is used for maintaining the water-filling state of suction pipe in the time that water pump shuts down, and stops the water in water pipe to return to water source, the upper energy-absorbing power while ensureing that with this water pump turns round again.What affect bottom valve function is its sealability, if poorly sealed, just has seepy question, and system will be difficult to realize automatically and control, and also not have the effect that prevents aqueous reflux.Existing bottom valve has been done a lot of improvement to the structure of valve body, spool etc., but less for the improvement of filter screen, if can not will block foreign material gear in outside or be broken into fractionlet, the sealing problem of bottom valve just can not fundamentally be resolved.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of double filter screen bottom valve of water pump, comprise valve body, filter screen, bolt, spool, seal ring, guide collar, described valve body and filter screen are bolted, described spool is positioned at valve body, one end of described spool is positioned at guide collar, the other end and seal ring are adjacent, described guide collar is fixedly connected on valve body inner side, described seal ring is between filter screen and valve body, it is characterized in that: also comprise screen cover, described screen surface is knife edge shape, described screen cover is positioned at outside filter screen and by bolt and filter screen, valve body is fixedly connected with.
The mesh-density of described filter screen is greater than the mesh-density of screen cover.
The material of described filter screen is aluminum alloy or stainless steel.
The material of described screen cover is ABS resin.
The beneficial effects of the utility model are: the foreign material in water source can be blocked in to outside at filter screen outer installment screen cover, screen surface is set to knife edge shape, make to block foreign material and be broken into fractionlet under the effect of water pump suction.Through filtering for the first time, even if there are the foreign material of obstruction to see through screen cover, under the effect that also can filter for the second time at knife edge shape filter screen, become fractionlet, thereby avoid the generation of obstructing problem, screen cover convenient disassembly, simple in structure, and there is the effect of protecting filter screen.
