Abstract
The invention discloses a low noise throttle cut off emptying valve and belongs to the field of valves. The low noise throttle cut off emptying valve comprises a valve body, a valve rod, a support and a valve cover, a valve sleeve sharing the same axis with the valve rod is arranged in the valve body, and a group of throttle grooves of different lengths are arranged on the circumference of the lower portion of the valve sleeve; the bottom of the throttle grooves are on the same axis and all the throttle grooves are symmetrically distributed periodically; the outer circumferences of an inlet section and an outlet section of valve body are provided with sound absorbing layers with mineral cotton filled inside. The low noise throttle cut off emptying valve effectively solves the problem of noises.
Description
Technical field
The present invention relates to valve field, specifically a kind of bass choke stop evacuation valve.
Background technique
Choke stop evacuation valve is a kind of double seal valve, plays in the conveyance conduit being mainly used in oil, rock gas, coal gas, blau gas etc., uses usually used as regulable control or cut-out.Such valve is a kind of novel throttling, cut-off, emptying product, has multistage throttle effect, the features such as restriction effect is obvious, sealing is reliable, convenient operating maintenance.
At existing choke stop evacuation valve in the throttling of valve, cut-out, equalizing orifice arranges to alleviate in operation torsion, combination seal etc. all very much progress.But still there are distinct issues in actual conditions application: in high pressure or middle pressure ring border, the noise of valve is abnormal large, and noise is also a kind of pollution, is in noisy environment the health worked to workman for a long time and causes damage.
Summary of the invention
The present invention aims to provide a kind of bass choke stop evacuation valve, to solve the problem.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of bass choke stop evacuation valve, comprise valve body, valve rod, support, valve gap, it is characterized in that: the valve pocket being provided with the same axis with valve rod in described valve body, valve pocket lower circumference is provided with at least one group of throttling groove different in size; On the same axis, each throttling groove is periodic symmetry distribution in the bottom of described throttling groove; Described valve body inlet section and outlet section excircle are also provided with sound-absorption layer, are filled with slag wool in sound-absorption layer.
Further, be provided with the flap of flexible connection in described valve pocket, under flap, excircle is provided with and scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating valve pocket.
Further, described flap contacts circumferential surface and has at least two and place the annular groove sealing O shape and enclose with valve pocket, be provided with storage slag chute between two annular grooves.
Beneficial effect of the present invention is:
One, flap contacts circumferential surface and has at least two and place the annular groove sealing O shape and enclose with valve pocket, and be provided with storage slag chute between two annular grooves, under flap, excircle is provided with and scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating tubular valve pocket.Scrape slag cutting edge effectively to strike off and be adsorbed on various medium crystallization on valve pocket inner peripheral surface or foreign material, and the residue these struck off stores in storage slag chute, makes between flap and valve pocket without stuck phenomenon.It also avoid flap simultaneously and occur that when opening the pressure reduction that jam causes is unstable, make flap and valve pocket run more stable, reduce vibration, reduce noise.
Two, valve pocket lower circumference is laid with throttling groove different in size, each throttling groove periodic symmetry distribution.While the effective throttling of length throttling groove, ensure that in valve opening process, the flow shape that is in line increases progressively, and seamlessly transits to decrease differential pressure vibration when structural design medium flows out simultaneously, plays the effect of noise-reducing.
Three, valve body inlet section and outlet section excircle are also provided with sound-absorption layer, are filled with slag wool in sound-absorption layer.Slag wool is a kind of staple shape inorfil, it have the light thermal conductivity of quality little, do not burn, the feature such as mothproof, inexpensive, corrosion-resistant, chemical stability is good, sound absorbing capabilities is good.Arrange slag wool, effective control noise source, carries out sound-absorbing to noise source, weakens the diffusion of noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low noise throttle stop emptying valve provided by the invention.
Fig. 2 is valve pocket schematic diagram provided by the invention.
Fig. 3 is that valve pocket provided by the invention launches schematic diagram.
Mark in figure: 1 be valve body, 2 be valve seat, 3 be flap, 4 be valve pocket, 5 be valve rod, 6 be sound-absorption layer, 9 for throttling groove.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of bass choke stop evacuation valve, comprises valve body 1, valve rod 5, support, valve gap, it is characterized in that: be provided with the valve pocket 4 with the same axis of valve rod 5 in described valve body 1, and valve pocket 4 lower circumference is provided with at least one group of throttling groove 9 different in size; On the same axis, each throttling groove 9 distributes in periodic symmetry in the bottom of described throttling groove 9; Described valve body 1 entrance and outlet section excircle are also provided with sound-absorption layer 6, are filled with slag wool in sound-absorption layer 6.Be provided with the flap 3 of flexible connection in described valve pocket 4, flap 3 times excircles are provided with scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating valve pocket.Described flap 3 contacts circumferential surface and has at least two and place the annular groove sealing O shape and enclose with valve pocket 4, be provided with storage slag chute between two annular grooves.
In use, medium is by the entrance of valve body, and the slag wool in sound-absorption layer 6 carries out sound-absorbing, controls noise source, weakens the diffusion of noise.When medium is by tubular valve pocket 4, the throttling groove 9 different in size that lower circumference is laid with, each throttling groove 9 periodic symmetry distribution.Length throttling groove 9, effectively while throttling, ensure that in valve opening process, and the flow shape that is in line increases progressively, and seamlessly transits to decrease differential pressure vibration when structural design medium flows out simultaneously, plays the effect of noise-reducing.When medium flows out from valve outlet section, sound-absorption layer 6 carries out sound-absorbing again, weakens noise further.The present invention is adopted effectively to solve choke stop evacuation valve noise problem.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
