Arrival end and the port of export are inclined to set, and screen pipe is provided with screen pack, and screen pipe has filter chamber, it is characterised in that：Should
The side wall of screen pipe is extended with the filtering branch pipe with arrival end and port of export axis perpendicular, and the filtering branch pipe has and filtering
The pre- filter chamber of chamber connection, one end of pre- filter chamber are connected by restricted flow passage with arrival end, and the other end of pre- filter chamber passes through screen pack
On mesh connected with filter chamber, the side of filter chamber towards the port of export offers the filtering pipe through-hole connected with the port of export.
In said structure, fluid is entered valve body by arrival end and flowed into after restricted flow passage reduces flow by pre- filter chamber
Flowed out after filter chamber filtering from filtering pipe through-hole through the port of export, because filter chamber of the prior art directly connects with entrance point, Jie
Mass flow body directly rushes at screen pack into valve body, destruction is easily impacted to filter screen, and some graininess impurity are in impulse force
The port of export can be directly entered with fluid under driving, this structure is reduced between filter chamber and arrival end by current limliting fluid
Impact to screen pack, in addition, the pre- filter chamber is located at the top of filter chamber, filter is from top to bottom directly acted under gravity
On the net, more preferable filter effect can be played, but because flow is smaller, the impact of fluid can be avoided to cause to damage to filter screen,
Extend its service life.
As the further setting of the present invention, there is the valve port that is connected with the pre- filter chamber on the valve body, in the valve port
Body is installed with, body has the body endoporus being adapted to pre-flock intracavitary footpath, annular groove is offered on the body outer peripheral face, annular
Capping is embedded with groove, the capping and annular groove are tightly connected and leave the chamber that confluxes between capping and body, conflux chamber and the set
Internal hole insertion, the body are provided with the shrink tunnel of pass-through entry end and the chamber that confluxes.
In said structure, conflux chamber between shrink tunnel and pre- filter chamber between capping and body, work as medium fluid
The chamber that confluxes is come together in after entering shrink tunnel from arrival end, the fluid impingement force is buffered, and fluid pours from the chamber that confluxes again
Filter chamber is filtered.
As the further setting of the present invention, the valve body is provided with the bonnet corresponding with valve port, the bonnet and capping
Between form the aerial drainage chamber of sealing, the return flow line of insertion aerial drainage chamber and the port of export is additionally provided with the valve body.
In said structure, the port of export of the valve body is penetrated by the aerial drainage chamber at return flow line and bonnet, can be by the valve
Lid is opened, and fluid can carry out both ends shunting from aerial drainage chamber and the port of export.
As the further setting of the present invention, the screen pack includes tubular skeleton and the net being installed on skeleton outer peripheral face
Cloth, the skeleton both ends are set in opening, and skeleton one end open has flanging edge towards the port of export, another end opening of skeleton, should
Flanging is along being embedded in filtering tube wall, and there is skeleton the one end on flanging edge to be provided with fixed end cap, and the fixation end cap includes can
The positioning seat that stretches into skeleton opening and skeleton flanging is connected to along upper lid, lid and positioning seat integrally connected.
In said structure, the skeleton of the fixation end cap and the screen pack is interference fitted, or is coordinated by screw thread, can be facilitated
The dismounting and change screen pack.
As the further setting of the present invention, the side wall of the filtering branch pipe towards the port of export, which is provided with, tilts wall extension, should
Wall extension is tilted to be vertically arranged relative to screen pipe axis, and the inclination wall extension one end is connected with filtering branch pipe side wall, this inclines
The other end of oblique wall extension connects with the junction of screen pipe and valve body, and the filtering pipe through-hole is arranged on the inclination wall extension
On.
In said structure, the setting of the inclination wall extension causes the screen pipe to be completely embedded with valve body, coordinate it is compact, can be with
It is substantially reduced volume.
Using such scheme, the present invention is compact-sized, small volume, good filtration effect, service life length.
The invention will be further described below in conjunction with the accompanying drawings.
