Abstract
The utility model discloses an automatic switching mechanism for a filter. The automatic switching mechanism comprises a tank body and upper covers; the tank body is fixedly connected with the upper covers through bolts; two piston mechanisms are arranged in the tank body; the upper cover of each piston mechanism is provided with an electromagnetic valve A and an electromagnetic valve B; an inlet is formed in one end of the tank body, and two outlets are formed in the other end of the tank body; two pipelines are led out from the inlet end of the tank body through a joint, and each pipeline is connected with the corresponding electromagnetic valve A; two pipelines are led out from the outlet ends of the tank body through joints and are connected with the electromagnetic valves B; each piston mechanism comprises a piston and a spring; the bottom of each spring is placed on the top of the corresponding piston; the top of each spring is pressed against the inner wall of the top of the corresponding upper cover; a sealing plane is formed in a channel at which an inlet and an outlet are joined at the bottom of each piston; and the bottom of each piston is tightly pressed on the corresponding sealing plane through fluororubber. The automatic switching mechanism for the filter has the advantages that off and on of the filter can be switched over by the automatic switching mechanism, remote automatic control is realized, accuracy is high, and controllability is also high.
Description
Technical field
The utility model relates to the filter mechanism for automatically switching.
Background technology
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.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 technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of the utility model provides the high filter mechanism for automatically switching of a kind of precision.
The utility model solves the technical scheme that its technical problem adopted:
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 magnetic valve A and magnetic valve B all are installed, said casing one end has import, and the said casing other end has two outlets; Said entrance point leads to two pipelines through joint; Every pipeline is connected with magnetic valve A respectively, and said each port of export leads to a pipeline through joint, and said pipeline is connected with magnetic valve B; Said piston mechanism comprises piston and spring; Said spring bottom places top land; 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 fluorubber.
The contact-making surface of said loam cake and casing is provided with the O RunddichtringO.
The beneficial effect of the utility model is: when fluid gets into casing from import, the magnetic valve A of loam cake upper inlet direction often leaves, and the magnetic valve B of Way out is normally closed; Fluid gets into magnetic 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; Fluorubber on the piston is pressed on the sealing plane, does not make fluid get into outlet.When filter superpressure photos and sending messages, magnetic valve A is often left become normally closed, the normally closed change of magnetic 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.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
Wherein: 1, casing, 2, loam cake, 3, bolt, 4, the O RunddichtringO, 5, magnetic valve A, 6, magnetic valve B, 7, import, 8, outlet, 9, joint, 10, pipeline, 11, piston, 12, spring, 13, sealing plane, 14, fluorubber.
The specific embodiment
As illustrated in fig. 1 and 2, the filter mechanism for automatically switching of the utility model 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 contact-making surface of casing 1, is provided with two piston mechanisms in the casing 1; Magnetic valve A5 and magnetic 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 other end has two outlets 8; Import 7 ends lead to two pipelines 10 through joint 9; Every pipeline 10 is connected with magnetic valve A5 respectively, and each exports 7 ends and leads to a pipeline 10 through joint 9, and pipeline 10 is connected with magnetic 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 fluorubber 14.
When fluid gets into casings 1 from import 7, the magnetic valve A5 of loam cake 2 upper inlets 7 directions often leaves, and the magnetic valve B6 that exports 8 directions is normally closed; Fluid gets into magnetic 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; Fluorubber 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, magnetic valve A5 is often left become normally closed, the normally closed change of magnetic 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.
