Abstract
The utility model relates to a high-pressure cage type adjusting valve with a multi-hole throttling type valve cage. The valve cage adopted by the adjusting valve has the structure as follows: the lower part of the side wall around the valve cage is provided with a plurality of through holes for changing the flow area and the flow characteristic. The four groups of the through holes are symmetrically arranged on the side wall around the valve cage. Since the high-pressure cage type adjusting valve adopts the porous throttling type valve cage, the mediums are collided with each other at the center of the valve cage after being jetted from each pair of small holes, so that the buffer role is played due to the energy consumption when the mediums are collided with each other, and the possibility of the formation of eddy current is reduced. Therefore, the noise caused by the high-pressure medium is greatly reduced, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of cage type regulating valve, particularly a kind of high pressure cage modulating valve that has porous section streaming valve cage.
Background technique
The structure of the valve cage of tradition cage type regulating valve is promptly left 4 to 12 hollow windows on valve cage shown in Fig. 2,3, and change Flow characteristics by the discharge area that changes window.When the pressure medium height of regulating; Pressure reduction is bigger; When the high speed MEDIA FLOW is crossed the cage valve, medium several windows from the valve cage evenly flow into valve cage, after synthetic then one flow valves, this valve cage center that is flowing in produces very easily that eddy current, secondary flow etc. are complicated to flow, because medium sudden contraction and sudden enlargement, make the flow field extremely inhomogeneous, be easy to generate noise, also cause the damage of part in the valve easily.
Dismountable and can cause the part of changes in flow rate in the valve that valve cage is with fluid directly contacts by the change of discharge area, so the design of valve cage directly influences the using effect of whole valve.
Summary of the invention
In view of the problem that above-mentioned prior art exists, the utility model provides a kind of high pressure cage modulating valve that has porous section streaming valve cage.Present design is to be provided with 4 to 12 hollow window form by original valve cage to be improved to that to be provided with according to certain rules the porous section of arranging streamed, shown in Fig. 4,5.When the pressure medium height, when pressure reduction was big, arranging to reach by the difference of through hole on the valve cage changed the discharge area, and then changes the purpose of Flow characteristics.Valve cage is divided into etc. hundred, correction etc. hundred and linear characteristic.
The technological scheme that the utility model is taked for achieving the above object is: a kind of high pressure cage modulating valve that has porous section streaming valve cage, comprise valve cage, it is characterized in that, be provided with several through holes that are used to change discharge area and Flow characteristics in the bottom of described valve cage circumferential side wall.
The beneficial effect that the utility model produced is: because the high pressure cage modulating valve has adopted the valve cage that has the porous section streaming, after medium sprays into aperture from each, medium collides mutually at the center of valve cage, during collision owing to consumed energy, play the effect of buffering, reduced the possibility that eddy current forms.Thereby reduced the noise that high-pressure medium produces significantly, the working life of having improved valve.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 4 and Fig. 5, what the utility model adopted is the valve cage that has the porous section streaming, and several through holes 4-1 is located at the bottom of valve cage 4 circumferential side walls, and its effect is to change discharge area and Flow characteristics.Several through holes 4-1 on valve cage 4 circumferential side walls is provided with four groups altogether, four groups of through hole 4-1 successively symmetric arrays on valve cage 4 circumferential side walls.The quantity of every group of through hole equates; The equal diameters of through hole.In four groups of through holes, the arrangement regulation of one group and three groups through hole equates and is symmetrical; The arrangement regulation of two groups and four groups through holes equates and is symmetrical.
The high pressure cage modulating valve that has porous section streaming valve cage is made up of valve body 1, valve seat pad 2, valve seat 3, valve cage 4, valve hole part 5, bonnet gasket 6, valve gap 7 etc.At first valve seat 3 is placed on the valve seat pad 2 in the valve seat orifice of valve body 1; The valve cage 4 that will have through hole is then packed in the valve body 1 and is placed on the upper-end surface of valve seat 3; Valve hole part 5 is packed in the valve body by valve cage 4; Reinstall bonnet gasket 6, valve gap 7 is placed on the valve body 1, compress, and compress valve seat 3, valve cage 4 simultaneously, flow to shown in the arrow among Fig. 1 with stud nut.
Valve cage directly contacts with flowing medium, and can directly influence the negotiability of control valve by the change of discharge area, therefore, is one of most important trim in the valve.
Valve cage shown in Fig. 4,5 is the identical aperture of a plurality of diameters that distributes in whole stroke range, regulates flow by different the arranging of aperture, changes the Flow characteristics of valve.Valve cage can be divided into etc. hundred, correction etc. hundred, linear characteristic.Can design the quantity of little pore size distribution by the calculated flow rate area according to the valve cage of different qualities.When the pressure height, when the spool of the bigger medium of pressure reduction by control valve, throttling end face that valve cage forms, rate of flow of fluid sharply increases suddenly, and static pressure descends suddenly, utilizes the porous Throttle Principle of medium, after medium sprays into from the symmetrical aperture of each group, medium collides mutually at the center of valve cage, owing to consumed energy, play the effect of buffering during collision, reduced the possibility that eddy current forms.Thereby reduced the noise that high-pressure medium produces significantly, the working life of improving valve.
