Abstract
The utility model relates to a pressure balanced type multihole noise-reducing sleeve guide regulating valve which comprises a valve body, wherein a medium inlet and a medium outlet are arranged in the valve body; a valve cap is installed at the upper end of the valve body; a valve seat, a sleeve, a valve core and a pressing sleeve are installed in an inner cavity of the valve body; the valve seat is installed at the bottom of the inner cavity of the valve body; the sleeve is installed on the valve seat; the valve core is sleeved with the sleeve; the pressing sleeve is installed above the sleeve; and the medium inlet is arranged under the valve core. The pressure balanced type multihole noise-reducing sleeve guide regulating valve is characterized in that the sleeve wall of the sleeve is provided with a plurality of flow passage holes which are communicated with the medium outlet in the valve body. The valve core is connected with a valve rod, and the valve rod passes through the pressing sleeve and the valve cap and extends out of the outer side of the valve cap. A valve cap winding pad is arranged at the joint of the valve cap and the valve body. The pressure balanced type multihole noise-reducing sleeve guide regulating valve can effectively reduce the noise generated in the use process of a valve, prolong the service life of a valve trim and reduce the overall use cost of the valve.
Description
Technical field
The utility model relates to a kind of modulating valve, especially a kind of pressure-balancing type porous noise reduction sound cage guiding modulating valve.
Background technique
At present, control flow rate in the industry is regulated the size of flow and generally all can be used modulating valve.But under some special operating mode, when pressure difference was very big, modulating valve can produce very big noise, and velocity of medium also can increase, thereby had accelerated the washing away of valve internals shortened the working life of valve.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and a kind of pressure-balancing type porous noise reduction sound cage guiding modulating valve is provided, and can reduce the noise that produces when using, and has prolonged the service time of modulating valve.
According to the technological scheme that the utility model provides, said pressure-balancing type porous noise reduction sound cage guiding modulating valve comprises valve body, and medium import and media outlet are set on valve body; Valve gap is installed in upper end at said valve body, at the inner chamber of valve body valve seat, sleeve, spool and gland is installed, and valve seat is installed in the bottom of body cavity; Installing sleeve on valve seat; Jacket casing is located on the spool, and gland is installed above sleeve, and the below of spool is the medium import; Characteristic is: on the barrel of said sleeve, be provided with several runner apertures, said runner aperture is communicated with media outlet on the valve body.
Said spool is connected with valve rod, and valve rod passes gland and valve gap and stretches out the valve gap outside.
The valve gap wound gasket is installed in joint at said valve gap and valve body.
The valve seat wound gasket is installed in joint at said valve seat and valve body.
In the joint of said sleeve, gland and spool the balanced seal ring is set.
On said spool, be provided with balancing orifice, this balancing orifice is communicated with the bottom of spool and the top of spool.
The described pressure-balancing type porous of the utility model noise reduction sound cage guiding modulating valve can reduce the noise pollution that valve in use produces effectively, prolongs the working life of trim, reduces the whole user cost of valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the unfolded drawing of the described sleeve of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1～shown in Figure 2: pressure-balancing type porous noise reduction sound cage guiding modulating valve comprises valve body 1, valve gap 2, spool 3, valve rod 4, valve seat 5, sleeve 6, gland 7, balanced seal ring 8, valve seat wound gasket 9, valve gap wound gasket 10, runner aperture 11 etc.
As shown in Figure 1, the utility model comprises valve body 1, and medium import and media outlet are set on valve body 1; Valve gap 2 is installed in upper end at said valve body 1, in the joint of valve gap 2 and valve body 1 valve gap wound gasket 10 is installed; Inner chamber at said valve body 1 is installed valve seat 5, sleeve 6, spool 3 and gland 7, and valve seat 5 is installed in the bottom of valve body 1 inner chamber, in the joint of valve seat 5 and valve body 1 valve seat wound gasket 9 is installed; Installing sleeve 6 on valve seat 5; Sleeve 6 is set on the spool 3, and the below of spool 3 is the medium import, and gland 7 is installed above sleeve 6; Joint at sleeve 6, gland 7 and spool 3 is provided with balanced seal ring 8, when valve closing, is guaranteed the sealing of valve by balanced seal ring 8; Said spool 3 is connected with valve rod 4, and valve rod 4 passes gland 7 and valve gap 2 and stretches out valve gap 2 outsides;
As shown in Figure 2, on the barrel of said sleeve 6, be provided with several runner apertures 11, said runner aperture 11 is communicated with media outlet on the valve body 1; When medium fashionable from the medium inlet flow of valve body 1; Can only pass through from the runner aperture 11 on the sleeve 6, runner aperture 11 produces eddy current consuming the medium energy, and the runner aperture 11 of medium from sleeve 6 through the time unexpected area diminish; Be divided into some threads; And through area increase suddenly behind the sleeve 6, the big high attenuation of acoustic energy quilt, thus play the effect that reduces noise;
On said spool 3, be provided with balancing orifice, this balancing orifice is communicated with the bottom of spool 3 and the top of spool 3; Said balancing orifice can make spool 3 tops and bottom be in pressure balance, and the unbalanced force that need overcome during valve working is reduced to minimum, thereby can reduce to drive the drive unit specification of valve proper functioning, reduces the whole cost of valve.
The utility model can effectively reduce the noise pollution that valve in use produces, and prolongs the working life of trim, reduces the whole user cost of valve.
