Description
Technical field
This utility model relates to a kind of rapid escape valve, the sealing structure between ball float and the ferrule circle of a kind of rapid escape valve.
Background technology
Rapid escape valve is the important device in conveying water-system pipeline.Rapid escape valve is arranged on eminence or have the place held one's breath in conveying water system.When pipeline produces a large amount of gas, rapid escape valve can the air in purging line rapidly, when pipeline produces a small amount of gas, rapid escape valve can a small amount of gas in purging line in time, to produce vapour lock in preventing pipeline, improve emptying effectiveness；When producing negative pressure in pipeline, rapid escape valve can quickly suck gas, prevent pipeline from damaging 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, there is import the lower end of valve body, there is outlet the upper end of valve body, has ball float bucket, the bottom of ball float bucket to have water inlet in valve body, ball float is had in ball float bucket, there is spool above ball float, in valve body, have the valve seals matched with spool, in the outlet of valve body, have the guide ring on valve axis, having the tubular guide post being inserted in guide ring above spool, guide post mouth of pipe of one end below spool is embedded with ferrule circle.
The valve body of rapid escape valve, valve seals and spool composition breather cheek valve, ball float and the spool big capacity ball-cock assembly of composition, ball float and the mouth of pipe are embedded with the tubular guide post of ferrule circle and form little capacity ball-cock assembly.
nullAbove-mentioned ball-cock assembly is in use，Ball float rises on it contact on ferrule circle，Spool is promoted to rise the sealing making spool be against on valve seals to realize exit seal simultaneously also to realize tubular guide post，Ferrule circle is a pair sealing pair between the upper top of ball float，It it is again the driving member of ball float promotion spool rising，Ball float is directly to be against on the lip of ferrule circle，Make ferrule circle by abandoned bigger pressure，This can not retrain the seal pressure rational seal pressure considerably beyond the upper top line up sealing ring of ball float，This seal pressure sealing structure that can not retrain is irrational，Ferrule circle can produce bigger deformation under bigger pressure，Time length can damage ferrule circle，The ferrule circle of this rapid escape valve is because by abandoned bigger pressure，Greatly affect serviceability and the service life of rapid escape valve.
In prior art, do not have and ferrule circle can be made to be sealed the rapid escape valve of structure by reasonable seal pressure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, propose a kind of have ferrule circle can be made to be sealed the rapid escape valve of structure by reasonable seal pressure.
This utility model realizes with the following method.
nullRapid escape valve has cylinder valve，There is import the lower end of valve body，There is outlet the upper end of valve body，Ball float bucket is had in valve body，Water inlet is arranged at the bottom of ball float bucket，Ball float is had in ball float bucket，Spool is had above ball float，The valve seals matched with spool is had in valve body，The guide ring on valve axis is had in the outlet of valve body，The tubular guide post being inserted in guide ring is had above spool，Guide post mouth of pipe of one end below spool is embedded with ferrule circle，In the spool guide post lower end mouth of pipe and ball float have between top、Overcoat cartridge type connects neck，Inner sleeve is connected on ball float and pushes up，Outer sleeve is connected in below spool，The outer flanging of annular outside the oriented cylinder of upper nozzle of inner sleeve，Flanging in annular in the oriented cylinder of lower nozzle of outer sleeve，The external diameter of outer flanging is more than the internal diameter of interior flanging，The barrel of inner sleeve has radial direction through hole，After the upper nozzle of inner sleeve is against below spool，Rational seal pressure is had between top and ferrule circle on ball float.
This utility model is arranged on eminence or have the place held one's breath in conveying water system.Rapid escape valve is when naturalness, and ball float falls at ball float drum head, and the spool being connected neck with ball float inner and outer sleeves formula connected leaves valve seals, and ferrule circle is against on ball float.
When carry in water system when having a large amount of gas to need to discharge, carry the circular passage between import, valve body and ball float bucket of the gas in water system and outlet is discharged, after gas in conveying water system is discharged, water can enter in valve body, and allow ball float rise in entering ball float bucket, ball float rise can promote spool to move upward and be against on valve seals, close the outlet of rapid escape valve, prevents the water carrying in water system from discharging.
When the outlet of rapid escape valve is closed, the a small amount of gas produced in conveying water system can enter below the spool in valve body, gas makes ball float be lowered away from ferrule circle after entering valve body, a small amount of gas can be discharged through the radial direction through hole of inner sleeve barrel, ferrule circle and guide post, after a small amount of gas in conveying water system is got rid of, ball float can again rise and is against on ferrule circle, prevents the water carrying in water system from discharging.
When carrying generation negative pressure in water system, the ball float being connected with spool falls can be at ball float drum head, and spool leaves valve seals, outside gas negative pressure in rapid escape valve enters conveying water system, in elimination conveying water system.
The spool guide post lower end of the present utility model mouth of pipe has inner and outer sleeves formula to be connected neck with on ball float between top, after the upper nozzle of inner sleeve is against below spool, rational seal pressure is had between top and ferrule circle on ball float, inner sleeve is the driving member that ball float promotes that spool rises, ball float will not line up sealing ring be produced without constraint bigger pressure, be a kind of have ferrule circle can be made to be sealed the rapid escape valve of structure by reasonable seal pressure.
Below in conjunction with the accompanying drawings, the utility model is further described.
