Abstract
The invention discloses a silent throttling stop air release valve, and belongs to the field of valves. The silent throttling stop air release valve comprises a valve body, a valve rod, a support and a valve deck. A denoising assembly and a valve clack assembly are arranged in the valve body. The denoising assembly comprises a valve sleeve and a plate baffle. The valve sleeve is cylindrical and is vertically installed on the same axis as the valve rod. At least one set of throttling grooves of different lengths are formed in the circumference of the lower portion of the valve sleeve. The bottoms of the throttling grooves are located on the same axis. The throttling grooves are distributed in a symmetric periodic mode. The plate baffle is vertically arranged in an inlet passageway of the valve body. The plate baffle is in a hollow annular shape. Asymmetrical throttling holes are formed in the circumferential surface of the plate baffle. By means of the silent throttling stop air release valve, the problem that noise is produced by an existing throttling stop air release valve is effectively solved.
Description
Technical field
The present invention relates to valve field, specifically a kind of quiet 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 quiet 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 quiet choke stop evacuation valve, comprises valve body, valve rod, support, valve gap, it is characterized in that: be provided with noise-reducing assembly and flap assembly in valve body, noise-reducing assembly comprises valve pocket, spoiler; Described valve pocket is tubular, is vertically arranged on valve rod on same axis, and 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 spoiler is vertically arranged in valve body inlet passage, and spoiler is the circular of hollow, circumferential surface has asymmetric throttle orifice.
Further, described flap assembly comprises flap, valve seat, pressure ring and soft seal circle, and flap is movably connected in and is contained in 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.
Further, under described flap, excircle is provided with and scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating tubular valve pocket.
Beneficial effect of the present invention is:
One, tubular 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.
Two, 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.
Three, in valve body media inlet channel, be provided with the circular spoiler of hollow, spoiler have several asymmetric throttle orifice, when medium is by spoiler, throttle orifice plays pressure throttling action, in high and medium voltage environment, effectively reduce velocity of medium, play the effect reducing noise.

Mark in figure: 1 be valve body, 2 be valve seat, 3 be flap, 4 be valve pocket, 5 be valve rod, 6 be spoiler, 7 be pressure ring, 8 be soft seal circle, 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 quiet choke stop evacuation valve, comprises valve body 1, valve rod 5, support, valve gap, it is characterized in that: be provided with noise-reducing assembly and flap assembly in valve body 1, and noise-reducing assembly comprises valve pocket 4, spoiler 6; Described valve pocket 4 is tubular, is vertically arranged on valve rod on same axis, 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 spoiler 6 is vertically arranged in valve body inlet passage, and spoiler 6 is the circular of hollow, circumferential surface has asymmetric throttle orifice.Described flap assembly comprises flap 3, valve seat 2, pressure ring 7 and soft seal circle, and flap 3 is movably connected in and is contained in valve pocket 4.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.Described flap 3 times excircles are provided with scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating tubular valve pocket.
When using in high pressure or middle pressure ring border, medium is entering after in valve body 1, and first by spoiler 6, the asymmetric throttle orifice on spoiler 6, throttle orifice carries out pressure throttling, effectively reduces the flow velocity in valve body 1, plays the effect reducing 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.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.
