Description
Technical field
The utility model is related to a kind of cage type regulating valve, more particularly to a kind of heavy caliber noise reduction guide's cage type regulating valve.
Background technology
Traditional heavy caliber cage type regulating valve, uses the mode of valve cage loading valve body to be forced, as shown in fig. 6, leaning on
Valve cage is pressed on valve seat by bonnet thrust, and valve cage is directly contacted with valve seat, on the one hand, the thrust of bonnet is all acted on
On valve cage, it is easy to cause window to deform；On the other hand, the power being pressed on valve cage can be directly delivered on valve body by valve seat,
Easily cause seam position distortions under valve body.
Because the part of heavy caliber cage type regulating valve is in process because size is larger, to ensure the shadow of high-temperature expansion
Ring, the margin of tolerance is wider, therefore trim centering is poor in final assembly, and product complete machine leakage rate thus can be caused not to be inconsistent
Standardization requirement；And in order to ensure force request, the valve body wall thickness of valve seat location is installed as bore increase also can be increasingly
Thickness, therefore the casting difficulty of valve body moulding can be increased；And due to bore increase, the weight of valve cage can also increase, valve cage weight
It is relatively very heavy, after the completion of assembling, inspection and maintenance is such as needed, valve cage takes out valve cage from valve body and only holds window by both hands,
Firmly take out of, very big difficulty is brought to maintenance and replacing.Therefore from appropriate valve cage assembling mode to whole valve
Using being very crucial.
Large bore valves are big due to flow, easily produce noise；
In addition, valve aperture is bigger, leakage rate is bigger.Especially cage type regulating valve uses double sealing structure, and leakage rate is big
Just more protrude, better can accomplish IV grades, and poor even only accomplishes III level leakage quantity.
The content of the invention
In view of the problem of prior art is present, the utility model provides a kind of many grid noise reduction valve cages of suspension type and pilot-operated type
The heavy caliber cage type regulating valve of valve element, can avoid seam under valve cage window, valve body from deforming using suspension type valve cage structure, and
And there is the easily disassembled internals such as valve element, valve seat, valve cage, easy access and met by replacing valve cage in certain limit not
Same traffic requirement.Many grating type noise reduction valve cages can be effectively reduced noise.While pilot valve ensures the leakage of valve, no
The requirement exerted oneself to executing agency can be improved.
To achieve the above object, the technical scheme used is the utility model：A kind of heavy caliber noise reduction guide cage is adjusted
Save valve, including valve body, valve seat pad, screw, valve seat, pilot valve part, noise reduction valve cage, valve cage pad, bonnet gasket, valve
Lid, it is characterised in that：Between the noise reduction valve cage upper surface is provided with two lifting screws, the circumferential wall of noise reduction valve cage lower end
Separate several strip windows and constitute lattice structure；
Several screwed holes are interval with the lower seam of a circle in the valve body；
The valve seat is fixed in valve body on lower seam by several screws, and valve seat pad is provided between valve seat and valve body
Piece, the noise reduction valve cage is placed in valve body, and the raised platform of noise reduction valve cage is pressed in valve body on the seam of upper end by valve cage pad, drop
Make an uproar the lower surface of valve cage and the upper seat surface of valve seat leaves an intersegmental gap and constitutes suspension type, be connected with the pilot valve core of valve rod
Part is placed in noise reduction valve cage, and the bonnet is fixed on valve body through valve rod, and bonnet gasket is provided between bonnet and valve body.
The beneficial effects of the utility model are：
1）Valve cage assembling structure is that suspension type, i.e. valve cage are suspended in valve body on upper seam by valve cage pad, and valve cage
Lower end not with the feature contacts such as valve seat, valve cage is pressed in valve body by bonnet, pressure of the valve cage to seam under valve body is eliminated
Clamp force, it is to avoid seam is deformed under valve body.2）Because valve cage employs suspended structure, the thrust of bonnet is set all to act on
On valve cage step, influence of this active force to valve cage window position, the possibility of reduction window deformation are reduced.3）Due to valve
Cage employs suspended structure, and have devised 2 lifting screws in valve cage upper end, so passes through the work such as overhead traveling crane and lifting screw
Tool is easy to take out valve cage from valve body, easy access and replacing.
4）The window of noise reduction valve cage is multiple-grid case form, can effectively suppress the noise of valve.
5）Pilot valve part can be effectively reduced the leakage rate of valve, it is ensured that situation of the large bore valves in big pressure difference
Lower leakage rate can be up to state standards V grades.Go out simultaneously as valve is enterprising bottom, when closed, pressure difference is bigger, and closing is got over
Sternly；When opening, pilot valve is first acted, and effectively main valve plug can just be acted after pressure release, so exerting oneself not to executing agency
More requirements are proposed, it is cost-effective.
