Abstract
The utility model relates to a high-pressure single-seat adjustment valve, which comprises a valve body, a valve seat gasket, a valve seat, a valve core component, a valve deck gasket, a valve deck and a cylindrical valve cage. Four installation holes are arranged on the wall surface at the upper end of the valve cage, and four flow holes are arranged at the lower end of the valve cage. The valve seat is positioned on the valve seat gasket in a valve body cavity, the valve cage is positioned on the valve seat in the valve body cavity, and a valve core of the valve core component is arranged in the valve cage. One end of a valve rod of the valve core component is fixed with the valve core, the other end of the valve rod extends out of the valve deck fixed with the valve body, and the valve deck gasket is arranged between the valve body and the valve deck. The high-pressure single-seat adjustment valve is characterized in that functions of direction guide and guarantee of largest flow capacity are achieved, the valve cage guides the valve core component during total travel, the guide area is large, a guide function is good, and the valve core component is not easily to vibrate or shake, thereby ensuring closing performance and service life of the valve.
Description
Technical field
The utility model relates to a kind of single-seat adjusting valve, particularly a kind of high pressure single-seat adjusting valve.
Background technique
The spool guiding of control valve is extremely important for fluid control and valve closing, and the spool guiding of single seat control valve mainly can be divided into guiding, valve cage guiding etc.
(1) last guiding is meant through bonnet bush or leading truck etc. and is led in position, spool upper end;
(2) the valve cage guiding is meant through the valve cage internal surface spool whole outer surface is led.
The guiding design proposal of tradition single-seat valve is last guiding, and is as shown in Figure 3, and single seat spool 8 leads through 9 pairs of spool upper ends of leading truck.When the pressure medium of modulating valve is high, when pressure reduction was big, because the guiding area is less relatively, spool was easy to produce vibrations, shake, made to be not closed completely closely, phenomenons such as leading truck damage perhaps occurred.
Summary of the invention
Problem in view of the existing technology existence; The utility model provides a kind of high pressure single-seat adjusting valve; This modulating valve is high for pressure medium, and when pressure reduction was big, the guiding form of employing was the structural type (this guiding pattern usually is used in the cage valve) of total travel valve cage guiding.
The utility model is for realizing above-mentioned purpose; The technological scheme of being taked is: a kind of high pressure single-seat adjusting valve; Comprise valve body, valve seat pad, valve seat, valve hole part, bonnet gasket, valve gap, it is characterized in that: also comprise valve cage, said valve cage is a tubular; On the wall of valve cage upper end, be provided with four mounting holes, on the valve cage lower end, be provided with four metering orifices; Said valve seat is placed on the valve body cavity internal valve seat cushion sheet; Said valve cage is placed on the valve seat in the valve body cavity; The spool of said valve hole part places in the valve cage; One end and the spool of the valve rod of valve hole part are fixed, and the other end of valve rod stretches out outside the valve gap that fixes with valve body, is provided with bonnet gasket between valve body and the valve gap.
The characteristics of the utility model are: valve hole part leads to valve core outer surface through the valve cage inwall in the total travel process; Valve cage mainly plays guiding therein and guarantees the effect of maximum flow ability in this structure, and what really regulate flow is spool lower curve part.And valve seat is to be pressed in the valve body through valve cage and bonnet; This modular design makes the valve cage can automatic centering, guarantee that the coaxality of whole bottom is consistent basically, and valve cage leads to the valve hole part total travel; The guiding area is big; Leading role is good, makes valve hole part be not easy to produce vibrations, shake, has guaranteed closing performance and working life of valve.
