Have simple structure, with low costs, characteristics that the filter effect is good.
Description
Technical field
This utility model belongs to petroleum equipment technical field, more particularly to flow instrument filter.
Background technology
Filter is the auxiliary equipment of pipeline and effusion meter, can filter out various foreign bodies, and rising prevents line clogging, it is ensured that
The effect that instrument is normally run.Filter is indispensable a kind of device on pumped (conveying) medium pipeline, be typically mounted on air relief valve,
Relief valve, Valve for keeping constant water level, the import end equipment of square work filter miscellaneous equipment.At present, existing filtration device structure and operation are multiple
Miscellaneous, affected by environment big, use cost is high, and filter efficiency is low, and dangerous, not working, service life are short.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide flow instrument filter, has
The characteristics of simple structure, low cost, good filtration effect.
To achieve these goals, the technical solution used in the present invention is：Flow instrument filter, includes cylindrical mistake
Filter shell, filter housings upper end are connected with lid 9 by hinge 1, connect top cover lifting screw mandrel by locking nut on upper lid 9
5, the filter housings on the downside of upper lid are provided with lid revolution and support post 4, and clip folding screw mandrel 7 is located at lid and is connected with housing
Place is met, the entrance point 11 and the port of export 12 at the middle part of filter housings are connected with pipeline 13 by flange, and oral area sets in pipeline 13
There is drainage screen 10；Filter housings bottom is provided with blow-off pipe 8.
Described inlet side and outlet side are equipped with pressure gauge.
Described drainage screen 10 is a dismountable filter cylinder.
The beneficial effects of the utility model are：
Compared with prior art, the upper lid of this utility model filter is when locked clip device, between sealing ring and sealing surface
Without relative rotation, sealing ring is hardly damaged, so as to preferably protect sealing system.Filter has the filter cylinder of certain specification filter screen
Afterwards, its impurity is blocked, and when cleaning is needed, as long as dismountable filter cylinder is taken out, reloads after process.
Applicable media can be water, oil, gas；Advanced with structure, resistance is little, the characteristics of blowdown facilitates；Operation is more simple,
It is safe and reliable, go slick, do not affected by environmental change；Long service life, alleviates the labor intensity of operator, safeguards pole
For convenience；Especially use the benefit on high-pressure large-caliber pipeline obvious.Flow instrument filter is that I is being received for many years in a large number at company
On the basis of collection petrochina, sinopec market information and large-scale oil pipeline demand, with simple structure, low cost, effect is filtered
Really good the characteristics of.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Side views of the Fig. 2 for Fig. 1.
Fig. 3 is A-A in Fig. 1 to schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,2,3, flow instrument filter, cylindrical filter housing is included, filter housings upper end passes through
Hinge 1 is connected with lid 9, connects top cover lifting screw mandrel 5 by locking nut, set on the filter housings on the downside of upper lid on upper lid 9
There are upper lid revolution and support post 4, clip folding screw mandrel 7 is located at lid and housing junction, and the middle part of filter housings is entered
Mouth end 11 and the port of export 12 are connected with pipeline 13 by flange, and in pipeline 13, oral area is provided with drainage screen 10；Filter housings bottom
It is provided with blow-off pipe 8；
Described inlet side and outlet side are equipped with pressure gauge.
Described drainage screen 10 is a dismountable filter cylinder.
Outside shell ring is divided to two lobes and the locking of three lobes, and wherein DN40～200 are two lobes, and DN250～1000 are three lobes, are realized
Action simultaneously, uniform force during locking, reduce unlatching screw mandrel length, make the switch become more flexibility and reliability, while increase
Biting teeth area, is more practically applicable to the use of high-pressure large-caliber pipeline.The main pressure-containing member such as blind plate clip adopts forged steel, overall processing
Form.
Operation principle of the present utility model is：
When filter works, water to be filtered is entered by entrance point 11, flows through drainage screen, enters access customer by the port of export 12
Needed pipeline carries out process cycles, and the granule acrobatics in water is trapped within its interior.So constantly circulate, be trapped down
The granule for coming is more and more, and the rate of filtration is more and more slower, and the sewage of the port of export is still continuously entered, and filter opening can be increasingly
It is little, thus pressure differential is produced between import and export, when magnanimous difference reaches setting value, the signal of telecommunication is sent to by differential pressure transmitter
Controller, control system are started drive motor and are rotated by transmission component band moving axis, while sewage draining exit is opened, are arranged by sewage draining exit
Go out, after filter gauze cleaning is finished, pressure reduction is minimized value, and system returns to inceptive filtering shape, and system is normally run.It is so abundant
Filter space, the significant volume for reducing filter, lower intracavity be provided with backwash sucker.During work, turbid liquid Jing entrances enter
Enter filter cavity of resorption, and Jing partition board holes enter the inner chamber of filter element.It is trapped more than the impurity in filtration core gap, net liquid passes through gap
Epicoele is reached, is finally sent from outlet.
