Description
Technical field
The invention belongs to art of filters, particularly relate to a kind of big flow pressure regulation accurate filter.
Background technology
After entering automatization and NC postprocessing system along with industry, compressed air has been increasingly becoming an important power
Source.Due to corrosivity solid granulates such as the dust itself contained in air, iron filings and dirty, air, after compressor, can carry
There is a certain amount of moisture, easily corrode high-accuracy plant equipment.Therefore, flow into certainly in order to avoid the impurity in air and moisture
Dynamicization equipment, causes equipment fault, and technical staff often arranges filter, thus carries out the impurity in air and moisture
Filter, obtains the purest compressed air.
Such as Chinese patent notification number: CN204159184U, disclose a kind of filter, particularly to a kind of air-source treater
Pressure regulation filter.Its structure includes that drainage cup, described drainage cup are connected above processor body, described processor body front
Arranging air inlet, rear arranges gas outlet, and described processor body interior connects downwards the decompression being arranged within drainage cup
Valve, the spool of described air relief valve connects up the pressure regulating device being arranged at described processor bodies top, described pressure regulator
It is provided with diaphragm between structure and processor body.But, such filter, its air relief valve is arranged on inside filter element, this structure
Causing air relief valve inner cavity of component less, part is little with part fit clearance, causes throughput less, it is impossible to meet wanting of big flow
Ask.
Summary of the invention
The present invention is to overcome above-mentioned deficiency of the prior art, it is provided that a kind of big flow improving air mass flow is adjusted
Pressure accurate filter.
To achieve these goals, the present invention is by the following technical solutions:
A kind of big flow pressure regulation accurate filter, including filter body and the filter hood fixing with filter body lower end
Body, described filter body is provided with inlet and outlet, is provided with filter element, above the outside of described filter element in described filter hood body
Being provided with and seal the air deflector coordinated, air deflector is tightly connected with filter body, and air deflector is provided with diversion cavity, described filter
This internal inlet channel being provided with inlet communication, is provided with in described air deflector and controls break-make between inlet channel and diversion cavity
Pressure regulation chock plug and make the chock plug spring of pressure regulation chock plug return, is provided with the chock plug seat of location pressure regulation chock plug in the middle part of described air deflector,
The pod apertures of diversion cavity and filter interior it is communicated with between chock plug seat and air deflector outer wall.
In prior art, air deflector designs at filter element inner chamber, causes body and air deflector inner chamber little, and throughput is little；Pressure regulation
Chock plug designs at air deflector inner chamber, causes gap between pressure regulation chock plug and air deflector too small；Pressure regulation chock plug overall structure is too small, its
Less with the sealing surface of body fits, throughput is little.In this programme, air deflector is arranged on outside filter element, improve air deflector and
Chamber body volume, is arranged on below air deflector by filter element simultaneously, improves the gap between air deflector and filter element, increases gas
Flow.Additionally, due to air deflector is positioned at above filter element so that air enters from the pod apertures between chock plug seat and air deflector outer wall
In filter element, it is to avoid compressed air directly blows to cartridge surface, but is internally formed eddy flow at filter element, and the impurity in air is more
Easily sedimentation, thus further increase filter effect.Filter in this programme, at the base not changing filter profile size
On plinth, the flow of pressure regulation accurate filter is improved more than 5-7 times, meet the demand for mass flow air.
As preferably, in the middle part of described chock plug seat, it is provided with the chock plug groove being slidably matched with pressure regulation chock plug, the end of described chock plug groove
