Abstract
The utility model relates to a linear sealed type automatic air exhaust valve. The column-shaped inner cavity of the valve body is provided with a hollow float ball. The part approaching to the inner surface of a valve cover is provided with a sealed rubber cushion. The contact surface of the sealed rubber cushion and the float ball is a curved surface. The curved surface is provided with externally convex circular ring bodies with definite number. The utility model has reliable air exhaust function, tight combination of the float ball and the sealed glue cushion and no water leakage. The total weight of the utility model is one third of the existing air exhaust valve. The service life is long. The maintenance is convenient. The product cost reduces 60-70%.
Description
The utility model provides a kind of line closed automatic control pressure vent, and basic module comprises valve body, and the float that moves between suction port and the relief opening in valve body.Belong to the valve technology in the engineering element.
In hot-water heating system, often, cause hot water can not carry out the circulation of heat exchange effectively because a part of cool air can not in time be discharged from pipeline.In order to get rid of pipeline hollow gas, easily assembling on the position of cool air, a kind of Lever type outlet valve is installed usually, the floating drum in the valve body, the lifting along with the valve SEA LEVEL VARIATION, and then affect lever to control the keying of outlet valve, realize exhaust sealing purpose.This outlet valve just can be finished the sealing of plunger to relief opening owing to need to amplify with lever the buoyancy that rises of floating drum.Therefore, in case floating drum, lever, or their points of attachment produce and make or alignment error, all can in use take place to lose efficacy and leak.Chinese patent discloses a kind of automatic control pressure vent No. 86201255, and technical characterstic shows as the plunger that is provided with annular groove in the upper-end surface of floating drum, and this plunger is along with floating drum lifting and sliding in the guide pin bushing that is connected with relief opening in valve body.Because rising to the fluid pressure of exhaust ports through tortuous passage (passage that the crack constituted between plunger and the guide pin bushing) is zero, and remains in the air in the tortuous position, owing to incompressibility, has also stoped the seepage of liquid effectively.Can not leak during this kind exhaust valve closure.But also exist structure complicated, machining accuracy height, plunger are easily become rusty extremely waits deficiency in guide pin bushing.
At the above-mentioned deficiency of existing outlet valve in the existing hot-water heating system, it is a kind of simple in structure that the purpose of this utility model is to provide, and processing and fabricating is easy, the closed automatic control pressure vent of the reliable line of degassing function.
Above-mentioned purpose of the present utility model realizes by taking following technical measures.
In the cylindrical inner chamber of valve body, the configuration hollow float; Press close to valve gap internal surface place seal rubber pad is set, sealing rubber cushion and ball float phase-contact surface are curved surface, and the evagination cirque body of some is set on this curved surface.
The closed automatic control pressure vent of line stands upright on pipeline and easily assembles the gas position.During normal the heating, full liquid makes the ball float come-up in the valve body cylinder chamber, and the evagination cirque body of seal rubber pad and the upper surface of ball float closely fasten, and sealing valve gap relief opening avoids hot water excessive.When the bubble coalescence that contains in the pipeline during to body cavity, liquid in the expulsion valve intracoelomic cavity gradually, ball float descends, and the valve gap relief opening is open-minded, and gas releases from relief opening, pours into valve body again to liquid, and the ball float come-up is sealed till the relief opening again.
If valve gap internal surface and the inside and outside surface of the seal rubber pad of pressing close to are concentric spherical, perhaps the hollow out sphere that the evagination cirque body of the some that is provided with on the seal rubber pad constitutes and the ball float face matches is then very favourable to effective sealed valve cap relief opening of ball float.If air inlet (liquid) mouthful place of closing at valve body is provided with the boss that supports ball float, can increase the flexibility that ball float rises and falls.These measures all are preferred technique scheme of the present utility model undoubtedly.
The closed automatic control pressure vent of line, degassing function is reliable, and ball float and seal rubber pad are in conjunction with closely, and be water-tight./ 3rd of a just existing outlet valve of overall weight.Long service life, maintenance are also convenient.Product cost reduces 60-70%.
Accompanying drawing is the structural representation of the closed automatic control pressure vent of line, and wherein accompanying drawing 1 is the sectional view of the closed automatic control pressure vent of line, and accompanying drawing 2 is the seal rubber pad sectional view, and accompanying drawing 3 is the partial enlarged drawing of seal rubber pad, and accompanying drawing 4 is the valve body organigram.Below in conjunction with accompanying drawing, further narrate technical characteristics of the present utility model by most preferred embodiment.
The basic module of the closed automatic control pressure vent of line includes valve body (1), and the ball float that disposes in the cylindrical inner chamber in valve body (2), has the valve gap (6) of exhaust port, and presses close to the seal rubber pad (3) that valve gap internal surface place is provided with.Sealing rubber cushion and ball float phase-contact surface are sphere, and the valve gap internal surface also is a sphere, and the evagination cirque body (5) of some is set on the inner ball surface of seal rubber pad, and evagination cirque body (5) also constitutes the hollow out sphere concentric with ball float.The inside and outside surface of valve gap internal surface, seal rubber pad, and evagination cirque body, they constitute the concentric circle sphere separately, and (4) are attachment bolt.
In the present embodiment, the evagination cirque body can be the 3-5 bar, and when the action of seal rubber pad was ball float (2) diameter 1/6-1/8, ball float sealing or the action of unlatching relief opening were the most flexible.
Claims (5)
1, the closed automatic control pressure vent of a kind of line, basic module comprises valve body, and the float that moves between suction port and the relief opening in valve body, it is characterized by in the cylindrical inner chamber of valve body the configuration hollow float; Press close to valve gap internal surface place seal rubber pad is set, sealing rubber cushion and ball float phase-contact surface are curved surface, and the evagination cirque body of some is set on this curved surface.
2, the closed automatic control pressure vent of line according to claim 1, it is characterized by the valve gap internal surface is concentric spherical with the inside and outside surface of pressing close to of seal rubber pad.
3, the closed automatic control pressure vent of line according to claim 1 and 2 is characterized by the evagination cirque body formation of the some that is provided with on the seal rubber pad and the hollow out sphere that the ball float face matches.
4, the closed automatic control pressure vent of line according to claim 3 is characterized by at air inlet (liquid) mouthful place of closing on of valve body the boss that supports ball float is set.
5, the closed automatic control pressure vent of line according to claim 1, the action that it is characterized by seal rubber pad are ball float (2) diameter 1/6-1/8.
