Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to a kind of ball valve with filtering function.
Background technique
Ball valve and filter are mounted in device conventional on pipeline, ball valve and filter are to be mounted on pipeline by flange at present, because long-time use can be at filter interior meeting accumulated impurity, now just need to pull down filter and carry out cleaning and filtering net, first unloading process turn-offs the ball valve of upstream, need the medium of downstream line inside all to emit simultaneously, and then the bolt of Fixed-Filter is all disassembled, take out filter webs, after cleaning filter net, also need to reinstall up, complex steps, need to spend a large amount of manpowers and time, efficiency is very low.
Model utility content
The purpose of this utility model is: in order to address the above problem, a kind of ball valve with filtering function simple in structure, easy to use is provided, it can be convenient for changing filter screen, can directly observe again the inner impurity situation of filter screen simultaneously, thereby change in time filter screen.
To achieve these goals, the technical solution of the utility model is:
With a ball valve for filtering function, comprise housing, be arranged on spool in described housing, be arranged on filter screen in described spool, be arranged on end cap and differential pressure gauge in described housing sidewall; Described spool is provided with places described filter screen groove; On described end cap, shrouding is set; Described spool is rotating is arranged on described enclosure interior, and described housing arranges the first pressure tappings and the second pressure tappings; Described the first pressure tappings is arranged on described filter screen front end; Described the second pressure tappings is arranged on described filter screen rear end; Described differential pressure gauge comprises body, be arranged on intrinsic piston, be arranged on the spring of described piston tip; Described body arranges the first connection mouth and the second connection mouth; Described the first connection mouth connects the first pressure tappings; Described the second connection mouth connects the second pressure tappings.
Further, described spool is spherical in shape; On described spool, be also provided with boss; The end of described boss is positioned at the outside of described housing.
Further, in described boss, be provided with breach.
Further, also comprise driveshaft; Described driveshaft one end coordinates with described breach, drives described Spool rotating.
Further, described end cap is bolted on described housing.
The utility model is owing to having adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
The utility model, owing to being provided with differential pressure gauge, can judge filter net jam situation according to the position of the piston of differential pressure gauge inside, can change in time filter screen, thereby ensures pipeline smoothness, enhances productivity; The utility model owing to being provided with shrouding on end cap, and end cap is connected with housing in conjunction with rotatable valve core by bolt, and rotary spool to correct position unloads shrouding, simultaneously can also cutting out pipeline, and then conveniently change filter screen.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model with the ball valve of filtering function.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of ball valve with filtering function, is characterized in that: comprise housing 1, be arranged on spool 2 in described housing 1, be arranged on filter screen 3 in described spool 2, be arranged on end cap 4 and differential pressure gauge 9 on described housing 1 sidewall; Described spool 2 is provided with places described filter screen 3 grooves; On described end cap 4, shrouding 6 is set; Rotating described housing 1 inside that is arranged on of described spool 2, described housing 1 arranges the first pressure tappings 11 and the second pressure tappings 12; Described the first pressure tappings 11 is arranged on described filter screen 3 front ends; Described the second pressure tappings is arranged on described filter screen 3 rear ends; Described differential pressure gauge 9 comprises body 91, be arranged on piston 92 in body 91, be arranged on the spring 93 on described piston 92 tops; Described body 91 arranges the first connection mouth 911 and the second connection mouth 912; Described the first connection mouth 911 connects the first pressure tappings 11; Described the second connection mouth 912 connects the second pressure tappings 12.
Preferably, described spool 2 is spherical in shape; On described spool 2, be also provided with boss 5; The end of described boss 5 is positioned at the outside of described housing 1.
Preferably, in described boss 5, be provided with breach 7.
Preferably, also comprise driveshaft 8; Described driveshaft 8 one end coordinate with described breach 7, drive described spool 2 to rotate.
Preferably, described end cap 4 is bolted on described housing 1.
When use, judge that according to the position of the piston 92 in differential pressure gauge 9 whether filter screen 3 is blocked, when the position of piston 92 arrives certain altitude, represent that filter screen 3 is blocked, need to change or clean, while changing filter screen 2, driveshaft 8 is arranged on breach 7, rotary spool 2, filter screen 2 is faced to end cap 4, the bolt being connected with housing 1 by dismounting end cap 4, pull down by whole end cap 4, take out filter screen 3, after filter screen 3 is cleaned, filter screen 3 is reinstalled on spool 2, end cap 4 is mounted on housing 1, counterrotating spool 2 can carry out normal operation, the operation of dismounting and change filter screen is very convenient quick, without valve entirety is disassembled from pipeline, also change in time filter screen, ensure the unimpeded of pipeline.
In sum, the utility model is simple in structure, easy to use, not only can be convenient for changing filter screen, can directly observe again the inner stopping state of filter screen simultaneously, thereby change in time filter screen.
