Abstract
The utility model discloses a single air valve, which comprises a valve body, a ball, an outer valve cover, an inner valve cover, an outer valve cover bolt and an inner valve cover bolt, wherein the outer valve cover bolt is connected with the outer valve cover and the inner valve cover; the inner valve cover bolt is connected with the inner valve cover and the valve body; a ball seat is arranged in the valve body; by forming an air vent through hole in the ball seat, parts such as a valve rod and a valve are eliminated; by arranging a sealing gasket on a contact part of the inner valve cover and the ball seat, the whole sealing performance of a ball valve is improved; and by arranging a coating outside the ball, the corrosion resistance of the ball is improved, and the service life of the ball valve is prolonged. The single air valve is simple in structure, low in manufacturing cost, convenient to maintain and long in service life.
Description
Technical field
The utility model relates to a kind of valve class, particularly relates to a kind of single air valve.
Background technique
The single air valve of tradition mainly is made up of valve body, valve, loam cake, spheroid, outer valve gap, interior valve gap, valve rod, ball float, exhaust nozzle etc.During gas in needing discharge conduit, the air in the pipeline gets in the body cavity under the pressure action of water, and discharges from exhaust nozzle; Water in the pipeline is full of in the body cavity thereupon; Make ball float under the buoyancy of water effect, move up exhaust nozzle is stopped up, reach sealing voluntarily.
The main feature of this type of ball valve is that working principle is simple, is applicable to general work media such as water, solvent, is widely used in every profession and trade.Yet though this type of ball valve has above-mentioned plurality of advantages, inner member is more, and manufacture cost is high, and inconvenient maintenance has hindered promoting the use of this kind valve body.
In order to address the above problem, various equivalent modifications is never developed suitable device, and the inventor works out a kind of single air valve based on industry experience for many years, has positive practicability.
The model utility content
The main purpose of the utility model is, overcomes the defective that existing single air valve exists, and a kind of single air valve of new structure is provided, and technical problem to be solved is to make it simple in structure, reduces manufacture cost, enhances productivity.Thereby be suitable for practicality more, and have the value on the industry.
The purpose of the utility model and solve its technical problem and adopt following technological scheme to realize.A kind of single air valve according to the utility model proposition; Comprise valve body, spheroid, outer valve gap and interior valve gap; Connect said outer valve gap and said in the outer valve gap bolt of valve gap, connects the internal valve bonnet bolt of said interior valve gap and said valve body, be provided with ball seat in the said valve body.
Aforesaid a kind of single air valve wherein, is evenly equipped with ventilative through hole on the ball seat.
Aforesaid a kind of single air valve wherein, is provided with sealing gasket, thickness 2-3mm between said interior valve gap and the said ball seat.
Aforesaid a kind of single air valve wherein, is outside equipped with coating at said spheroid, and said coating thickness is 2-3mm.
Aforesaid a kind of single air valve, wherein, said coating thickness 2.5mm.
By technique scheme, single air valve of the utility model has advantage at least:
Adopt single air valve of the utility model,, reduced parts such as the valve that plays regulating action, valve rod, and then practiced thrift manufacture cost, and the valve body overall structure is simpler through ventilative through hole is set on ball seat; Through between valve gap and ball seat, sealing gasket being set, make that the whole valve body sealability is better; Applying coating has increased the decay resistance of spheroid in the spheroid outside, further prolongs the working life of ball valve.
Above-mentioned explanation only is the general introduction of the utility model technological scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
