Description

A kind of heavy caliber low noise sleeve adjusting valve
Technical field
The utility model relates to a kind of adjusting control valve, particularly relates to a kind of heavy caliber low noise sleeve adjusting valve.
Background technique
Sleeve adjusting valve is in the current various industrial fluids control system, one of most widely used modulating valve product.Advantages such as the pressure reduction of permission is big though sleeve adjusting valve has, good stability, when valve aperture was big, the physical dimension of its critical piece sleeve and spool was corresponding just very big; Valve is in closure or openness moments; Suffered fluid impact power is very big, and spool receives very big circumferential unbalanced force effect simultaneously except that receiving axial unbalanced force; Very easily produce circumferential deflection, cause actuator and valve receive impact, the vibration and damage.The modulating valve that particularly uses at the high temperature and high pressure steam pipeline; When high temperature and high pressure steam passes through throttleng surface; Very easily produce phenomenons such as eddy current, flash distillation, cavitation, thereby produce very big impact and noise, and spool is produced very big washing away; Influence valve working stability and degree of regulation, produce very big influence of noise environment and health.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, and a kind of good heavy caliber low noise sleeve adjusting valve of low noise, anti-deflection, shock resistance that is applicable to that the high temperature and high pressure steam pipeline uses is provided.
The technical solution of the utility model is: a kind of heavy caliber low noise sleeve adjusting valve comprises silencing pot 1, valve body 2, spool 3, sleeve 4, valve gap 5, valve rod 6, torsional stop 7, connecting rack 8, fixture block 9, Gland 10, stuffing box packing 11, preloading spring 12, filler packing ring 13 and coupling.
Said valve body bottom is provided with a platform that is higher than valve body limit flange, and bracing reinforcement when making things convenient for valve to install has improved valve stability.
The sidewall of said sleeve is offered the rating curve window, and according to the needs that the different flow characteristic is regulated, window shape can be offered and be in line or equal percentage or fast katal linearity curve.The closed surface of contact of said spool and sleeve is taper contact seal, between sleeve and valve body, the valve gap gasket seal is housed.
Said lower cartridge is provided with silencing pot; Silencing pot circumferencial direction and bottom offer a lot of apertures as required; High temperature and high pressure steam through the contraction of these apertures, expand and turn to; Consume significant amount of energy and reduced pressure and flow velocity, also consumed acoustic wave energy simultaneously, play the effect that reduces noise.
Said valve rod lower end screws in behind the spool fastening with nut, and gets loose with fastening the preventing of locating stud.The valve rod upper end is passed valve gap and can be moved up and down, and is added with stuffing box packing between valve rod and the valve gap, and the stuffing box packing downside is provided with preloading spring, and its upside compresses with filler packing ring, Gland, to realize that reliable sealing prevents to leak outside.The valve rod upper end connects with fixture block with actuator.Utilize the fixture block connection to compare, make things convenient for being connected and fixed of actuator and valve rod, be convenient to the assembly and disassembly of valve and actuator with the connecting mode that valve rod outside thread of the prior art is screwed into actuator's push rod screw.
Said valve gap is fixed on the valve body with stud, pad and nut, is added with flexible graphite gasket between valve gap and the valve body, realizes that sealing prevents to leak outside.
On the sidewall of said connecting rack, be equipped with torsional stop, when spool moved up and down, the straight pin that stretch out said fixture block side slided in the anti-rotation groove of torsional stop, played leading role and produced circumferential deflection to prevent spool.
Advantage such as the utlity model has that action is stable, excellent noise reduction effect, shock resistance anti-deflection performance are excellent, be specially adapted to bore greater than DN200, the steam pipeline system that is prone to produce cavitation, flash distillation operating mode uses.
