Description
Technical field
The present invention relates to a kind of rapid escape valve, between the ball float and ferrule circle of particularly a kind of rapid escape valve
Sealing structure.
Background technology
Rapid escape valve is the important device in water-system pipeline is conveyed.Rapid escape valve is arranged in conveying water system
Eminence has the place held one's breath.When producing a large amount of gases in pipeline, sky that rapid escape valve can rapidly in purging line
Gas, when producing a small amount of gas in pipeline, a small amount of gas that rapid escape valve can in time in purging line, to prevent pipeline
Interior generation vapour lock, improve emptying effectiveness；When producing negative pressure in pipeline, rapid escape valve can quickly suck gas, prevent pipe
Road damages because of vibration.
Rapid escape valve is the combination valve of gravity-held check valve and ball-cock assembly.Rapid escape valve has cylinder valve, valve body
Lower end have import, there is outlet the upper end of valve body, there is ball float bucket in valve body, and there is water inlet the bottom of ball float bucket, had in ball float bucket
There is valve element ball float, ball float top, has the valve seals being engaged with valve element in valve body, have in the outlet of valve body in valve axis
On guide ring, have the tubular guide rod being inserted in guide ring above valve element, guide rod mouth of pipe of one end below valve element is embedding
There is ferrule circle.
Valve body, valve seals and the valve element composition breather cheek valve of rapid escape valve, ball float and the big exhaust of valve element composition
Measure the tubular guide post group of ball-cock assembly, ball float and the mouth of pipe embedded with ferrule circle into small capacity ball-cock assembly.
When in use, ball float rises contact thereon, and on ferrule circle, promote valve element to rise makes valve element to above-mentioned ball-cock assembly
It is against the sealing that exit seal is realized on valve seals while also realizes tubular guide rod, ferrule circle is both and ball float
Upper top between a pair of sealing pairs, be again ball float promote valve element rise driving member, ball float is directly to be against ferrule circle
On lip, making ferrule circle, this seal pressure that can not constrain is considerably beyond ball float by abandoned larger pressure
Upper top line up sealing ring rational seal pressure, it is this can not constrain seal pressure sealing structure be it is irrational, pipe
Mouth sealing ring can produce larger deformation under larger pressure, and the time, which has been grown, can damage ferrule circle, this Quick air-discharge
The ferrule circle of valve greatly influences the performance of rapid escape valve and made because by abandoned larger pressure
Use the life-span.
In the prior art, Quick air-discharge of the ferrule circle by the sealing structure of reasonable seal pressure can be made by not having
Valve.
The content of the invention
The invention aims to overcome above-mentioned deficiency, proposing that one kind has can be such that ferrule circle is rationally sealed
Than the rapid escape valve of the sealing structure of pressure.
The present invention is achieved using the following method.
Rapid escape valve has cylinder valve, and there is import the lower end of valve body, and there is outlet the upper end of valve body, has ball float in valve body
Water inlet is arranged at bucket, the bottom of ball float bucket, has ball float in ball float bucket, has valve element above ball float, there is what is be engaged with valve element in valve body
Valve seals, there is the guide ring on valve axis in the outlet of valve body, have the tubular being inserted in guide ring above valve element
Guide rod, the mouth of pipe of guide rod one end below valve element are embedded with ferrule circle, on the valve element guide rod lower end mouth of pipe and ball float
There is inner and outer sleeves formula to connect neck between top, inner sleeve is connected on ball float on top, and outer sleeve is connected in below valve element, inner sleeve it is upper
Annular outside edge outside the oriented cylinder of nozzle, the annular inside edge in the oriented cylinder of lower nozzle of outer sleeve, the external diameter of outside edge are more than
The internal diameter of inside edge, the barrel of inner sleeve have a radial direction through hole, after the upper nozzle of inner sleeve is against below valve element, ball float Shang Ding and pipe
There is rational seal pressure between mouth sealing ring.
The present invention is arranged on eminence in conveying water system or has the place held one's breath.Rapid escape valve floats in nature
Ball falls at ball float bucket bottom, and being connected the connected valve element of neck with inner and outer sleeves formula with ball float leaves valve seals, and ferrule circle supports
On ball float.
When convey in water system have a large amount of gases need discharge when, convey water system in gas through import, valve body with
Circular passage and outlet between ball float bucket are discharged, and after conveying the gas discharge in water system, water can enter in valve body, and enter
Ball float is allowed to rise in ball float bucket, ball float rise can promote valve element to move upwards and be against on valve seals, close rapid escape valve
Outlet, prevent convey water system in water discharge.
When the outlet of rapid escape valve is closed, valve body can be entered by conveying caused a small amount of gas in water system
Below interior valve element, gas makes ball float be lowered away from ferrule circle after entering valve body, and a small amount of gas can be through inner sleeve barrel
Radial direction through hole, ferrule circle and guide rod discharge, convey water system in a small amount of gas exclude after, ball float can rise again to
On ferrule circle, prevent from conveying the water discharge in water system.
When conveying generation negative pressure in water system, the ball float being connected with valve element falls and can leave valve body in ball float bucket bottom, valve element
Sealing ring, outside gas enter in conveying water system through rapid escape valve, eliminate the negative pressure in conveying water system.
There is inner and outer sleeves formula to connect neck between being pushed up on the valve element guide rod lower end mouth of pipe and ball float of the present invention, inner sleeve
After upper nozzle is against below valve element, there is rational seal pressure between top and ferrule circle on ball float, inner sleeve is that ball float pushes away
The driving member that movable valve plug rises, ball float will not line up sealing ring be produced without the larger pressure of constraint, be a kind of there is energy
Make rapid escape valve of the ferrule circle by the sealing structure of reasonable seal pressure.
Below in conjunction with the accompanying drawings, the present invention is further described.
