Abstract
The utility model discloses a kind of novel combined sewage exhaust valve, the valve gap comprising valve body and be connected with valve body, described valve body is provided with gas-entered passageway, and valve gap is provided with exhaust passage; Body base is provided with the linkage structure be connected with pipeline, and valve inner arranges ball float plug; Described valve inner is also provided with a tapered disk, and tapered disk is offered a center hole, the surrounding of center hole offers vent; Through a T-shaped connecting rod in described center hole, connecting rod is provided with spring, and connecting rod lower end is connected on fixing rod, and the two ends of described fixing rod are arranged in linkage structure.The tapered disk that the utility model adopts effectively has cushioned the steam water interface because pressure transient produces, and gas-liquid separation is carried out to steam water interface, fundamentally solve leakage water problem, play the scavenging action of outlet valve timely and effectively, substantially increase adaptability and the working life of outlet valve; Further, the utility model simplicity of design is reasonable, and cost easy to process is low, is easy to promote.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of novel combined sewage exhaust valve.
Background technique
In treatment of industrial water, in order to ensure the working efficiency of water quality and water pump, usually need to use outlet valve to carry out emission treatment to the air of assembling in pipe network, pipeline or other semi-hermetic type equipment with pressure.But in the process of air venting, because pressure change is rapid, easily cause general outlet valve to leak.For preventing outlet valve from leaking, usually install seal arrangement additional at body top, or increase trimmer valve, although these two kinds of modes can effectively prevent outlet valve from leaking, but implement to there is obvious defect in water treatment process at the scene: costly, utilization rate is low for reload buffer valve, and be difficult to safeguard; The mode of end sealing can not effectively be vented, and also easily causes equipment discontinuity, reduces the working life of equipment, and can reduce the utilization efficiency of water pump in water supply network, pipeline, increases energy consumption.These two kinds of methods all thoroughly cannot solve the seepy question in outlet valve using process.
Summary of the invention
The utility model for above-mentioned the deficiencies in the prior art, provide a kind of structure simple, safeguard convenient and effectively can be vented, thoroughly solve the novel combined sewage exhaust valve of seepy question.
The utility model for the adopted technological scheme that solves the problem is: a kind of novel combined sewage exhaust valve, the valve gap comprising valve body and be connected with valve body, and described valve body is provided with gas-entered passageway, and valve gap is provided with exhaust passage; Body base is provided with the linkage structure be connected with pipeline, and valve inner arranges ball float plug; Described valve inner is also provided with a tapered disk, and tapered disk offers a center hole, and the surrounding of center hole offers vent; Through a T-shaped connecting rod in described center hole, connecting rod lower end is connected on fixing rod, and the two ends of described fixing rod are arranged in linkage structure.
Described connecting rod is provided with spring.
The valve body at described gas-entered passageway top is provided with the first Sealing, the valve gap bottom described exhaust passage is provided with the second Sealing.
The tapered disk that the utility model adopts effectively has cushioned the steam water interface produced due to pressure transient, and gas-liquid separation is carried out to steam water interface, fundamentally solve leakage water problem, play the scavenging action of outlet valve timely and effectively, substantially increase adaptability and the working life of outlet valve; Further, the utility model simplicity of design is reasonable, and cost easy to process is low, is easy to promote.

Fig. 2 is the structural representation of tapered disk.
Wherein: 1, valve body; 2, valve gap; 21, exhaust passage; 3, linkage structure; 4, tapered disk; 41, center hole; 42, vent; 5, connecting rod; 51, spring; 6, fixing rod; 7, gas-entered passageway; 8, the first Sealing; 9, the second Sealing; 10, ball float plug.
Embodiment
In order to better understand the utility model, below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model application in the filter, a kind of novel combined sewage exhaust valve (valve body 1 diameter DN100mm, valve body 1 height 760mm), comprise valve body 1 and valve gap 2, valve body 1 is provided with gas-entered passageway 7, and the top of gas-entered passageway 7 is provided with the first Sealing 8 (the first Sealing 8 is rubber seal); Valve gap 2 is provided with exhaust passage 21, and the bottom of exhaust passage 21 is provided with the second Sealing 9 (the second Sealing 9 is rubber seal); The bottom of valve body 1 is provided with the linkage structure 3 be connected with pipeline, and valve body 2 inside arranges ball float plug 10, and ball float plug 10 is supported by the leg being fixedly connected on valve body 1 inwall; Described valve body 1 inside is also provided with a tapered disk 4, tapered disk 4 is offered a center hole 41, and the surrounding of center hole 41 offers vent 42; Through a T-shaped connecting rod 5 in described center hole 41, connecting rod 5 is provided with spring 51, connecting rod 5 lower end is connected on fixing rod 6, and the two ends of described fixing rod 6 are arranged in linkage structure 3.
Working principle of the present utility model is: when filter pressure stability normal exhaust, gas enters from gas-entered passageway 7, enters in valve body 1 by the vent 42 of tapered disk 4, from exhaust passage 21 Natural excrement at valve body 1 top, when filter backwash or when opening, tapered disk 4 is held up formation gap by a large amount of steam water interfaces produced due to pressure transient, steam water interface realizes effective separation by gap with vent 42, first gas enter valve body 1 cavity Natural excrement, subsequently, water level fast and stable in valve body 1 rises, hold up ball float plug 10 to contact with the second Sealing 9 (rubber seal), exhaust valve sealing is closed, simultaneously, tapered disk 4 gets back to original position (for tapered disk 4 can playback smoothly under the effect of self gravitation and spring 51, choosing of spring 51 meet Hooke's law), when backwash terminates or stop transport, the water of filter interior is emptying, and in this course, pressure reduces, and the water in valve body 1, under the acting in conjunction of self gravitation and external pressure, is discharged through vent 42, got back to filter, along with liquid level in valve body 1 declines, ball float plug 10 declines thereupon, until returning position.
In the utility model, valve body 1 model is different, and the relative dimensions (as the diameter of tapered disk, vent 42 quantity and aperture) of tapered disk 4 is also distinguished to some extent, and valve body 1 and tapered disk 4 relative dimensions match condition are in table 1.
Table 1 valve body 1 and tapered disk 4 specification are matched and are shown
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all any amendments, equivalent replacement and improvement etc. made within the utility model spirit and principle, are all contained within protection domain of the present utility model.
