Abstract
A filter with switch functions comprises a switch cap, a switch body, a filter cap, a filter screen, a connecting nut, a filter body, a valve rod, a valve core, a valve rod spring and a valve seat, wherein a switch controller consisting of the switch cap and the switch body and a cutoff valve consisting of the valve rod, the valve core and the valve rod spring are arranged in the filter, the switch controller is arranged on the upper portion of the filter, the cutoff valve is arranged on the lower portion of the filter, the switch controller controls the opening and closing of the cutoff valve through the valve rod of the cutoff valve, since the filter with switch functions is adopted, the problems that a filter of an existing agricultural liquid conveying system can not close a filter and block a conveying system in time, thus the whole conveying system is inconvenient to use. The filter with the switch functions has the characteristics of simple structure, simple manufacture and installation and convenient use.
Description
Technical field the utility model relates to a kind of filter with switching function, belongs to agricultural liquid induction system product technical field.
The filter that background technology is used in agricultural liquid or agricultural chemicals induction system at present, formed by crossing filter core and housing, the filter of this structure is in actual use when induction system needs local adjustment or maintenance, just can't close filter and blocking-up induction system timely, but must want earlier the valve of shutdown system, just can carry out the part and adjust or keep in repair, bring very big inconvenience can for like this use of whole induction system.
Summary of the invention the utility model provides a kind of a kind of filter with switching function of novelty, adopts the switching regulator stop valve structure, realizes just closing at any time when induction system need be carried out local adjustment or maintenance the purpose of filter and blocking-up induction system.
The technical solution adopted in the utility model is:
A kind of filter with switching function, comprise: deflating cap, switch body, filtering cover, screen pack, attaching nut, filtering bodies, valve rod, spool, valve rod spring, valve seat, in filter, be provided with by deflating cap, the on-off controller that switch body constituted and the stop valve that is constituted by valve rod, spool, valve rod spring, on-off controller is arranged at the upper position of filter, stop valve is arranged at the lower position of filter, and on-off controller is by the open and close of the valve rod control stop valve of stop valve.
Deflating cap is connected with switch body, and in two grooves in two flanges insertion filtering covers of switch body, switch body contacts mutually with valve rod, and deflating cap is installed on switch body top, and the rotation of deflating cap drives the switch body rotation and moves axially.
Valve rod, spool, valve rod spring are installed in the cavity that filtering bodies and valve seat constituted, valve rod one end is installed in the bracing frame hole of filtering bodies, the other end stretches out in the through hole of valve seat and with switch body and contacts mutually, spool, valve rod spring housing are loaded on the valve rod, spool is fixedlyed connected with valve rod, the valve rod spring is positioned at the lower position and the roof pressure spool of spool, and spool ended sealing with the through hole of valve seat when stop valve was closed under the roof pressure effect of valve rod spring.
The utility model beneficial effect is:
Owing to adopted a kind of filter of the present utility model with switching function, the filter that has solved existing agricultural liquid induction system can't cut out filter and blocking-up induction system and the problem of making troubles for the use of whole induction system timely, and that a kind of filter with switching function of the present utility model has is simple in structure, make the characteristics easy, easy to use of installing.
Description of drawings
Fig. 1: be a kind of structure of filter schematic diagram of the utility model with switching function.
Among Fig. 1: 1, deflating cap 2, switch body 3, filtering cover 4, screen pack 5, attaching nut 6, filtering bodies 7, valve rod 8, spool 9, valve rod spring 10, valve seat
The specific embodiment
As shown in Figure 1.
A kind of filter with switching function, mainly by: deflating cap 1, switch body 2, filtering cover 3, screen pack 4, attaching nut 5, filtering bodies 6, valve rod 7, spool 8, valve rod spring 9, valve seat 10, sealing ring, tapping screw are formed.
A kind of filter with switching function, comprise: deflating cap 1, switch body 2, filtering cover 3, screen pack 4, attaching nut 5, filtering bodies 6, valve rod 7, spool 8, valve rod spring 9, valve seat 10, in filter, be provided with on-off controller that is constituted by deflating cap 1, switch body 2 and the stop valve that is constituted by valve rod 7, spool 8, valve rod spring 9, on-off controller is arranged at the upper position of filter, stop valve is arranged at the lower position of filter, and on-off controller is by the open and close of the valve rod 7 control stop valves of stop valve.
Deflating cap 1 is connected with switch body 2, and in two grooves in two flanges insertion filtering covers 3 of switch body 2, switch body 2 contacts mutually with valve rod 7, and deflating cap 1 is installed on switch body 2 tops, and the rotation of deflating cap 1 drives switch body 2 rotations and moves axially.
Valve rod 7, spool 8, valve rod spring 9 are installed in the cavity that filtering bodies 6 and valve seat 10 constituted, valve rod 7 one ends are installed in the bracing frame hole of filtering bodies 6, the other end stretches out in the through hole of valve seat 10 and with switch body 2 and contacts mutually, spool 8, valve rod spring 9 are set on the valve rod 7, spool 8 is fixedlyed connected with valve rod 7, valve rod spring 9 is positioned at the lower position and the roof pressure spool 8 of spool 8, and spool 8 ended sealing with the through hole of valve seat 10 when stop valve was closed under the roof pressure effect of valve rod spring 9.
By as shown in the figure, filter is made up assembling, between each part sealing ring should be set in the combination of filters assembling process, to prevent leak of liquid, just can insert in the induction system after the combination assembling finishes and use.
After two flanges of switch body vertically insert in two grooves in the filtering cover, during 190 ° of lockings of rotary switch cap counterclockwise, driving switch body 2 rotates and moves axially downwards, switch body 2 roof pressure valve rods 7 move down, driving spool 8 moves down, thereby the through hole of filter valve seat 10 is opened, and filter just can normally carry out liquid communication and liquid filtering work, and spool 8 is opened size and moved the degree decision by deflating cap 1, switch body 2.
When deflating cap 1 clockwise direction turns to when upper, driving switch body 2 rotates and upwards moves axially, switch body 2 is moved back and is pressed valve rod 7 to move up, driving spool 8 moves up, thereby the through hole of filter valve seat 10 is closed, and filter just is blocked, and liquid just can not circulate, at this moment just can carry out part adjustment or maintenance activity, open filter by above-mentioned steps after work is finished and get final product.
