Abstract
The invention discloses an automatic switching mechanism for a filter. The automatic switching mechanism comprises a box body and an upper cover which are fixedly connected each other through bolts, wherein two piston mechanisms are arranged in the box body; a magnetic valve A and a magnetic valve B are mounted on each of upper covers of the piston mechanisms; an inlet is arranged at one end of the box body, two outlets are arranged at the other end of the box body; two pipelines extend out of the inlet end through a connector and are connected with the magnetic valve A; a pipeline extends out of each outlet end through a connector and is connected with the magnetic valve B; each piston mechanism comprises a piston and a spring; the bottom of the spring is arranged at the top of the piston; the top of the spring pushes against the inner wall of the top of the upper cover; a sealing plane is formed in a channel at which the inlet and the outlets are interacted at the bottom of the piston; and the bottom of the piston is compressed on the sealing plane through fluororubber. The automatic switching mechanism has the advantages that the switching from disconnecting to connecting is realized, the remote automatic control is also realized, the precision is high, and the controllability is strong.
Description
Technical field
The present invention relates to the filter mechanism for automatically switching.
Background technique
Filter is indispensable a kind of device on the fed sheet of a media pipeline, is installed in the entrance point of reduction valve, Decompression valves, 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.Generally, filter does not have automatic switching control equipment, and time-consuming, the effort of operating, discharging instability or easy interruption more can not realize remote auto control.Therefore, need provide a kind of new technological scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide the high filter mechanism for automatically switching of a kind of precision.
The technical solution adopted for the present invention to solve the technical problems is:
The filter mechanism for automatically switching comprises casing and loam cake, connects through bolt between said casing and the loam cake; Be provided with two piston mechanisms in the said casing; Cover on each piston mechanism solenoid valve A and solenoid valve B all are installed, said casing one end has import, and the said casing the other end has two outlets; Said entrance point leads to two pipelines through joint; Every pipeline is connected with solenoid valve A respectively, and said each outlet end leads to a pipeline through joint, and said pipeline is connected with solenoid valve B; Said piston mechanism comprises piston and spring; Said spring bottom places piston head; Said spring top and loam cake top inner wall offset, and said piston base zone forms sealing plane in the passage that import and outlet cross, and said piston base is pressed on the sealing plane through fluorine rubber.
The surface of contact of said loam cake and casing is provided with the O RunddichtringO.
The invention has the beneficial effects as follows: when fluid gets into casing from import, the solenoid valve A of loam cake upper inlet direction often leaves, and the solenoid valve B of Way out is normally closed; Fluid gets into solenoid valve from pipeline respectively; Get in the loam cake again and piston base, because piston upper and lower pressure is the same, piston is under spring action; Fluorine rubber on the piston is pressed on the sealing plane, does not make fluid get into outlet.When filter superpressure photos and sending messages, solenoid valve A is often left become normally closed, the normally closed change of solenoid valve B is often left, and the loam cake inner fluid gets into outlet; Piston produces pressure reduction up and down, and piston moves upward, the direction of flow outlet; Realized realizing remote auto control by not leading to logical conversion, precision is high, controllability is strong.

Embodiment
As illustrated in fig. 1 and 2, filter mechanism for automatically switching of the present invention comprises casing 1 and loam cake 2; Be fixedly connected through bolt 3 between casing 1 and the loam cake 2, loam cake 2 is provided with O RunddichtringO 4 with the surface of contact of casing 1, is provided with two piston mechanisms in the casing 1; Solenoid valve A5 and solenoid valve B6 all are installed on the loam cake 2 of each piston mechanism, and casing 1 one ends have import 7, and casing 1 the other end has two outlets 8; Import 7 ends lead to two pipelines 10 through joint 9; Every pipeline 10 is connected with solenoid valve A5 respectively, and each exports 7 ends and leads to a pipeline 10 through joint 9, and pipeline 10 is connected with solenoid valve B6; Piston mechanism comprises piston 11 and spring 12; Spring 12 bottoms place piston 11 tops; Spring 12 tops and loam cake 2 top inner wall offset; Piston 11 bottom sections form sealing plane 13 in the passage that import 7 and outlet 8 cross, piston 11 bottoms are pressed on the sealing plane 13 through fluorine rubber 14.
When fluid gets into casings 1 from import 7, the solenoid valve A5 of loam cake 2 upper inlets 7 directions often leaves, and the solenoid valve B6 that exports 8 directions is normally closed; Fluid gets into solenoid valve from pipeline 10 respectively; Get in the loam cake 2 again and piston 11 bottoms, because piston 11 upper and lower pressure are the same, piston 11 is under spring 12 effects; Fluorine rubber 14 on the piston 11 is pressed on the sealing plane 13, does not make fluid get into outlet 8.When filter superpressure photos and sending messages, solenoid valve A5 is often left become normally closed, the normally closed change of solenoid valve B6 is often left; Loam cake 2 inner fluids get into outlet 8, and piston 11 produces pressure reduction up and down, and piston 11 moves upward; The direction of flow outlet; Realized realizing remote auto control by not leading to logical conversion, precision is high, controllability is strong.
