Abstract
The utility model discloses a sleeve combined multi-level depressurization adjusting valve which comprises a valve body. An inlet flow channel is arranged on the right side of the valve body. An outlet flow channel is arranged on the left side of the valve body. The inlet flow channel is communicated with the outlet flow channel through a valve seat mounting hole in the bottom of a middle cavity of the valve body. The sleeve combined multi-level depressurization adjusting valve is characterized in that the valve body middle cavity is provided with a front flow guide wing and a back flow guide wing, the front flow guide wing is arranged on the inlet flow channel bottom face of the connecting portion of the inlet flow channel and the valve body middle cavity, a back flow guide wing is arranged on the inner wall, opposite to the inlet flow channel, of the valve body middle cavity. According to the sleeve combined multi-level depressurization adjusting valve, the turbulent condition of media when the media flow inside the valve body can be obviously improved, flow resistance is reduced finally, and accordingly the pressure recovery coefficient is lowered, the flow coefficient is obviously improved, the flow capacity of the valve is large, and meanwhile impact noise when fluid passes through the valve is lowered, and service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of sleeve combination multilevel decompression modulating valve.
Background technique
Thereby the great majority of septum valve in the market change the flow direction of medium, the pressure that flow velocity changes medium by the structural type that changes trim, sometimes also be inadequate by changing trim entirely, the optimal design that also needs valve body, valve body is the most important pressure part of directly following medium contact in the control valve, the flow path designs of conventional high-tension modulating valve valve body is that the inside nominal diameter according to valve, installation dimension, flange distance and the various flange standard of trim are determined to form the trend of various curves in the valve body stream through smooth connection again.Too high when pressure medium, flow velocity is too fast, is easy to produce block stream, so not only the valve body lumen is damaged, and affects the flow coefficient of valve, also can cause very large impact noise.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of medium turbulent condition in the flow process in valve body of improving, and reduces impact noise, improves the sleeve combination multilevel decompression modulating valve in working life.
The utility model is implemented by the following technical programs:
Sleeve combination multilevel decompression modulating valve, comprise valve body, inlet channel is established on the valve body right side, the valve body left side sets out a mouthful runner, inlet channel communicates with outlet flow through the valve seat mounting hole of valve body lumen bottom, it is characterized in that: flap before and after the valve body lumen is established, front flap is located at the inlet channel bottom surface of inlet channel and valve body lumen connecting part, and rear flap is located in the valve body of inlet channel on the cavity wall.Front flap is the fusiformis boss on pinnacle, front and back, and rear flap is the vertical rib that arranges, and the rib top is shrunk to the pinnacle.
In technique scheme, we have carried out rational design to the stream of valve body, add a front flap and rear flap at traditional valve body stream, before and after flap the obvious medium turbulent condition in the flow process in valve body of having improved is set, flow resistance is reduced, thereby reduced pressure-recovery factor, and then flow coefficient is obviously improved, the valve negotiability is larger; Avoid simultaneously produce blocking stream, the destruction that the valve body lumen is caused reduces, and reduces impact noise, improves valve working life.
As preferably, front and back flap and valve body are one piece casting.
As preferably, establish outer sleeve, inner sleeve, upper bush in the valve body lumen, inside and outside sleeve is pressed abd fixed on the valve seat by upper bush, and valve seat is installed at the valve seat mounting hole.
As preferably, spool is actively installed on the endoporus of inner sleeve and upper bush by the sealing of metal C type circle, metal C type circle opening up, and metal C type circle arranges at the endoporus junction plane of inner sleeve and upper bush.Above-mentioned design can improve the reliability of sealing.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A view of valve body among Fig. 1.
Embodiment
Describe details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, sleeve combination multilevel decompression modulating valve of the present utility model, comprise valve body 1, valve gap 13, valve seat 2, outer sleeve 8, inner sleeve 9, upper bush 11, spool 12 and valve rod 15, inlet channel 4 is established on valve body 1 right side, valve body 1 left side sets out mouthful runner 3, inlet channel 4 communicates with outlet flow 3 through the valve seat mounting hole 16 of valve body lumen 6 bottoms, flap before and after valve body lumen 6 is established, front flap 7 is the fusiformis boss on pinnacle, front and back, front flap 7 is located at inlet channel 4 bottom surfaces of inlet channel and valve body lumen connecting part, rear flap 5 is located on valve body lumen 6 inwalls of inlet channel 4, rear flap 5 is the vertical rib that arranges, the rib top is shrunk to the pinnacle, and front and back flap and valve body are one piece casting; Described outer sleeve 8, inner sleeve 9, upper bush 11 are in the 6 interior settings of valve body lumen, inside and outside sleeve is pressed abd fixed on the valve seat 2 by upper bush 11, valve seat 2 is installed at valve seat mounting hole 16, upper bush 11 is fixed by valve gap 13, spool 12 is actively installed on the endoporus of inner sleeve 9 and upper bush 11 by 10 sealings of metal C type circle, metal C type circle 10 opening up, metal C type circle 10 arranges at the endoporus junction plane of inner sleeve 9 and upper bush 11, valve rod 15 is connected on the spool 12, seals by stuffing box 14 between valve rod 15 and the valve gap 13.
Above-mentioned sleeve combination multilevel decompression modulating valve, when medium enters from inlet channel 4, medium is under the effect of front flap 7, enter valve body lumen 6 by a plurality of positions, again by entering outer sleeve 8 under rear flap 5 drainage in the valve body lumen 6, enter again inner sleeve 9 after reducing a lot by outer sleeve 8 pressure mediums, the very large reduction of getting back of the pressure of medium, by valve seat 2 last one decks pressure is dropped to required pressure range fully at last, boring area by changing each layer sleeve and size change flow velocity and the pressure of medium like this, flap has obviously improved fluid turbulent condition in the flow process in valve body before and after increasing in valve body, flow resistance is reduced, thereby reduced pressure-recovery factor, and then flow coefficient is obviously improved, the valve negotiability is larger; Avoid simultaneously produce blocking stream, the destruction that the valve body lumen is caused reduces, and reduces impact noise, improves valve working life.
