Description
Technical field
The utility model relates to a kind of modulating valve, especially relates to a kind of low noise modulating valve.
Background technique
Modulating valve is a kind of regulating controller in the combination instrument, be to produce to carry out one of important step in the process automatic regulating system, it is accepted the output signal of regulation meter and closes and Open valve, reach the isoparametric automatic adjusting of pressure, temperature, flow and liquid level, can be widely used in the automatic adjusting and the telecontrol of chemical industry, oil, metallurgy, electric power, light textile industry.Described modulating valve mainly contains single-seat adjusting valve and sleeve adjusting valve.Single-seat adjusting valve is uneven formula structure, is made up of valve body, valve seat, spool, valve rod, valve gap, stuffing box etc., can accept different control with different actuator's combinations.Valve body and valve seat, valve cover chamber pass through gasket seal, can prevent to leak outside and interior leakage, spool has curvilinear structures such as equal percentage, straight line, spool links to each other with valve rod, and valve rod passes valve gap and can move up and down, and realizes that by stuffing box sealing prevents to leak outside between valve rod and the valve gap, valve rod moves up and down under the effect of actuator, move up and down thereby drive spool, change the Flow area of spool and valve base chamber, thereby reach the purpose of automatic adjusting process parameter.Sleeve adjusting valve is a balance type structure, is made up of valve body, sleeve, spool, valve rod, valve gap, stuffing box etc., can accept different control with different actuator's combinations.Valve body and sleeve, valve cover chamber can prevent to leak outside and interior leakage by gasket seal, and sleeve is one to be similar to cylinder type, is pressed in the valve body lumen by valve gap.Have the window of curves such as equal percentage, straight line on the sleeve wall, spool is contained in the sleeve, and closed realization of valve core sealed cover and sleeve lining sealing surface seals.Spool links to each other with valve rod, valve rod passes valve gap, can move up and down, valve rod and valve cover chamber realize that by stuffing box sealing prevents to leak outside, valve rod moves up and down under the effect of actuator, moves up and down thereby drive spool, change the Flow area between spool and sleeve window, thereby reach the purpose of automatic adjusting process parameter.As the patent No. is that 200520071497.2 model utility discloses a kind of cage balance type single-seat adjusting valve, it mainly adopts valve rod to connect with spool, balance ring seat, gimbal, energization ring and sleeve are formed sleeve assembly and are installed on the valve body, the loam cake flange connects loam cake with bolt with valve body, Packing seat, filler, Gland and pressing plate are installed on the valve rod respectively.But present modulating valve, medium is easy to generate eddy current etc. by the body cavity throttleng surface time, thereby produce very big noise, and throttling element is produced very big washing away, thereby influence the stability and the degree of regulation of modulating valve, reduce working life, and noise causes very big influence to environment.
Summary of the invention
The technical problem that the utility model mainly is that noise is big when solving existing in prior technology and using, the spool life-span is short etc. provides a kind of simple in structure, noise is low, the spool life-span is long porous valve core type low noise modulating valve.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of valve cage formula low noise modulating valve, comprise valve body, spool, valve rod and valve gap, it is characterized in that being provided with in the described valve body inlet passage and the outlet passage that staggers up and down, valve body lumen between inlet passage and the outlet passage is provided with valve seat, valve seat and the spool that can move up and down are adaptive, spool links to each other with a valve rod, described valve gap is passed in described upper end, and on valve gap, be provided with a gland, be provided with described balance spring between gland and the valve gap, be provided with a porous noise reduction valve cage in the described valve body lumen, this valve cage is located therein with spool, and outlet passage and lumen are separated.Spool has equal percentage or linear curve, and the sealing surface of its sealing surface and valve seat coincide and realizes sealing.Described spool top is connected with described valve rod outside thread, and is fixed with pivot pin by an internal thread, and described valve rod passes the pilot hole and the stuffing box hole of valve gap, and prevents to leak outside with packing box seal.Described valve rod moves up and down under the effect of actuator, changes the Flow area between spool and valve cage, thereby reaches the purpose of automatic adjusting process parameter.The aperture that is distributed with many process calculation Design on the described low noise valve cage cage wall and sorts by special position, this aperture can play the effect of rectification to medium, thereby effectively reduces noise and wash away.
As preferably, be provided with valve seat between described inlet passage and the lumen, described spool and valve seat are suitable.Spool moves up and down the spacing that can regulate with valve seat, thereby reaches the purpose of regulation valve body flow, and when both cooperated fully, then modulating valve was closed.
As preferably, the both sides up and down of described valve cage compress sealing with valve gap and valve seat respectively.This design makes the fluid that carries out valve body must pass through valve cage, to reach noise reduction, to eliminate the effect of cavitating.
As preferably, be provided with stuffing box packing between described gland and the balance spring, the both sides up and down of stuffing box packing are respectively equipped with liner and lower liner.
As preferably, described inlet passage, outlet passage and the valve body lumen S-shaped structure that is connected.The structural distribution of S shape can be so that fluid be mobile more smooth and easy, the excessive impact of having avoided fluid to produce in flow process.
The beneficial effect that brings of the present utility model is, the technical problem that noise is big when solving existing in prior technology and using, the spool life-span is short etc. has realized simple in structure, the characteristics such as noise is low, do not have cavitation erosion, the spool life-span is long of modulating valve.
