Description
Technical field
The present invention relates to a kind of reverse directions to rinse fore filter, available for the water in purification house ornamentation pipeline, belongs to water purification
Processing technology field.
Background technology
At present, in sanitary ware water purification industry, for thick purified water fore filter product in use, filtering
The easy dirt deposits of device filter core, secondary pollution is caused to water quality, this just needs to carry out disassembly, cleaning or replacement to filter core.For
The disassembly, cleaning of filter core, dismounting is relatively time consuming, is easily damaged filter core, and clean filter core after dismantling, not only time-consuming and laborious, is also less prone to
It cleans up, while professional is needed to operate.Filter core is replaced, then increases the use cost of filter core.It is moreover, existing with inverse
Fore filter repercussion effect unobvious of direction pre-washing function, and water flow is smaller, also there are it is of high cost the problem of.
Invention content
It can be used for the inverse with reverse direction pre-washing function of purification house ornamentation pipeline water the purpose of the present invention is to provide a kind of
Fore filter is rinsed in direction, to solve the technical issues of fore filter disassembly, cleaning of the prior art bother.
The present invention adopts the following technical scheme that：
A kind of reverse direction rinses fore filter, and including filter core and the housing being arranged on outside filter core, the housing includes
The upper shell and lower housing being sealed connected together, upper shell are equipped with inlet and outlet, be equipped in the upper shell into
It connects inside water cavity, the water inlet and intake antrum, is connected inside the water outlet and filter core, the upper shell includes position respectively
Upper seal and lower seal in intake antrum upper and lower part offer water flowing in the upper seal and lower seal
Mouthful, selector bar is fitted in the intake antrum, the top of selector bar is worn at the top of the outlet pass of upper seal and upper shell successively
Go out, position of the selector bar between upper seal and lower seal is equipped with for the sealing with outlet pass sealing cooperation
Pad, the lower housing bottom are equipped with blowdown valve.
The upper shell is arranged on intake antrum periphery, and lower housing is arranged on filter core periphery.
For the upper shell together with intake antrum integrally connected, the inlet and outlet are integrally attached to upper shell
On.
The selector bar top is connected with the handwheel for being arranged on hull outside.
It is located at water outlet outside the upper shell and water inlet is equipped with nut and for being connected on house ornamentation pipeline
Articulation, the nut are threaded in water outlet and water inlet in upper shell, the articulation and the mutually embedding connection of nut.
The articulation is plastic article or metalwork.
The articulation connect or is threadedly coupled with house ornamentation pipeline welding.
The present invention opens water outlet, closes blowdown valve in user's just common water state, moves down selector bar until close
Packing is contacted with lower seal, and gasket and the outlet pass in lower seal are in sealing contact at this time, and flow is by upper seal at this time
On outlet pass enter the space between filter core and lower housing, water is flowed into inside filter core after flowing through filter element filtering, then by being discharged
For users to use, this state is filtration condition for mouth outflow.When reverse direction rinses state, water outlet is closed, opens blowdown valve, to
Dynamic selector bar is moved up until gasket is contacted with upper seal, gasket and the outlet pass in upper seal are in sealing contact at this time,
Flow enters the space inside filter core by the outlet pass in lower seal at this time, and flow is rinsed filter core, subsequently into filter
Space between core and lower housing, the water after cleaning flow through blowdown valve discharge, this state cleans state for reverse direction.The present invention's
It is according to market practicability and investigation that reverse direction, which rinses fore filter, is targetedly designed and developed, is using client
In to be more convenient more fitting practical, do not need to professional and disassembly, cleaning or replacement, the letter of reverse direction flushing operation carried out to filter core
It is single, while filter core service life is improved, do not influence water flow.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, the reverse direction of the present embodiment rinses fore filter packet to the structure of an embodiment of the present invention
It includes
Filter core 1 and the housing being arranged on outside filter core, the housing include the upper shell 21 being sealed connected together under
Housing 22, upper shell 21 are equipped with water inlet 3 and water outlet 4, are equipped with intake antrum 5 in the upper shell 21, the water inlet 3 with
5 inside of intake antrum connects, and the water outlet 4 is connected with 1 inside of filter core, and the upper shell 21 includes being located on intake antrum 5 respectively
Portion and the upper seal 51 of lower part and lower seal 52 offer outlet pass in the upper seal 51 and lower seal 52
53, selector bar 6 is fitted in the intake antrum 5, and the top of selector bar 6 is successively from the outlet pass of upper seal 51 and upper shell 21
Top is pierced by, and position of the selector bar 6 between upper seal 51 and lower seal 52 is equipped with for close with outlet pass 53
The gasket 2 of cooperation is sealed, 22 bottom of lower housing is equipped with blowdown valve 7.The upper shell 21 is arranged on 5 periphery of intake antrum, under
