Description
Technical field
The utility model relates to a kind of cage type regulating valve, particularly a kind of heavy caliber suspension type cage type regulating valve.
Background technique
Traditional heavy caliber cage type regulating valve, it is forced adopting pack into the mode of valve body of valve cage, by the valve gap impacting force, valve cage is pressed on valve seat, as shown in Figure 3, due to the part of heavy caliber suspension type cage type regulating valve in course of working because size is larger, be the impact that guarantees high-temperature expansion, tolerance range is wider, therefore when final assembly, the trim centering is poor, can cause that thus product complete machine leakage rate does not meet standard-required; And, in order to guarantee force request, the valve body wall thickness of valve seat location is installed along with the bore increase also can be more and more thicker, therefore can increase the casting difficulty of valve body moulding; And, because bore increases, the weight of valve cage also can increase, valve cage weight is relatively very heavy, and after assembling completes, as to need inspection and maintenance be also very difficult.Therefore selecting suitable valve cage assembling mode is very crucial to the use of whole valve.
Summary of the invention
Problem in view of the prior art existence, the utility model provides a kind of heavy caliber suspension type cage type regulating valve, adopt the suspension type valve cage structure can avoid seam under valve cage window, valve body distortion to occur, and there is the easily dismountings of internals such as spool, valve seat, valve cage, easy access and meet traffic requirements different in certain limit by replacing valve cage.
The utility model for achieving the above object, the technological scheme adopted is: a kind of heavy caliber suspension type cage type regulating valve, comprise valve body, valve seat pad, valve seat, valve hole part, valve cage, valve cage pad, bonnet gasket, valve gap, it is characterized in that: be interval with several screws on seam under one of bottom circle in described valve body, in described valve body, upper end is provided with a circle raised flanges, be provided with the screw corresponding with the several tapped holes that are provided with on seam under valve body one circle on a ring support face of described valve seat, described valve cage upper-end surface is provided with two lifting screws, and the periphery of valve cage upper end is provided with a circle projection platform, described valve seat is placed on the valve seat pad that in valve body, one circle lower seam in bottom is provided with, several screws of valve seat and several tapped holes of valve body align and by screw, valve seat are fixed in valve body, described valve cage is packed in valve body, the valve cage upper end protruding platform of one circle is overlapped on the valve cage pad that in valve body, upper end one circle raised flanges is provided with, the upper seat surface of the lower end surface of valve cage and valve seat leaves an intersegmental gap, the described valve hole part that two seal rings are housed is packed into by valve cage in valve body, described valve gap is fixed on valve body, the inner circle crowning of valve gap is pressed on valve cage projection platform by bonnet gasket.
The beneficial effects of the utility model are:
1) our the large diameter valve cage mounted distribution structure of design is suspension type, being valve cage is suspended in valve body on flange by the valve cage pad, and lower end does not contact with parts such as valve seats, by valve gap, it is pressed in valve body, remove the impacting force of valve cage to seam under valve body, avoided seam under valve body distortion to occur.Be that valve cage directly contacts with valve seat and traditional heavy caliber cage type regulating valve adopts, by valve gap, valve cage be pressed in valve body, the power be pressed in like this on valve cage is directly delivered on valve body by valve seat, easily causes that under valve body, the seam position is out of shape.
2) because valve cage has adopted suspended structure, the impacting force of valve gap is all acted on the valve cage step, reduced the impact of this active force on valve cage window position, reduce the possibility of window distortion.And traditional heavy caliber cage type regulating valve adopts, be that valve cage directly contacts with valve seat, the impacting force of valve gap all acts on valve cage, is easy to cause that window is out of shape.
3) because valve cage has adopted suspended structure, and design 2 lifting screws in the valve cage upper end, be easy to valve cage is taken out from valve body like this easy access and replacing by instruments such as overhead traveling crane and lifting screws.And traditional heavy caliber cage type regulating valve to be valve cage directly contact with valve seat, and do not design the lifting screw, only have and hold window by both hands so take out valve cage from valve body, firmly take out of, give maintenance and change and brought very large difficulty.
4) due to the suspension type valve cage in the suspension type cage type regulating valve and 2 Sealings of the employing of the sealing between spool, reduced the possibility of valve leak, even have one to be damaged in using at the scene, also can not use and impact complete machine.And traditional heavy caliber cage type regulating valve
Valve cage and spool between sealing adopt 1 Sealing, there is no the backup seal ring, if after in using at the scene, seal ring is damaged, complete machine
Can not normally use.
