Description
Technical field
The present invention relates to a kind of bellows spool pipe valve shape valve, can be formed with shut-off valve more particularly to one kind or
The functional character of two kinds of valves of telescoping valve, and as the pipe valve shape valve that shut-off valve or telescoping valve use.
Background technology
Two kinds of common forms of pipe valve shape valve have shut-off valve and telescoping valve.Traditional shut-off valve and telescoping valve are in the application
With respective advantage and disadvantage, for example, having the advantages of shut-off valve：When closed to the good airproof performance of medium, can realize to medium
Featuring rigid cutting-off, shortcoming has：During closing, valve rod medium active force suffered in the axial direction is larger, and required executing agency is also larger,
Particularly in the case of heavy caliber, big pressure difference, power bigger that valve rod is born limits its application range；Conventional sleeve
Valve mainly has two kinds of two seat sleeve valve and single seat telescoping valve, and two seat sleeve valve is to pass through spool（Opening and closing element）On two sealing surfaces
With two sealing surfaces on sleeve, two sealing pairs are formed when being closed to medium implementation sealing, single seat telescoping valve is to pass through
By in the above-mentioned two sealing pair of two seat sleeve valve, one close to valve deck side is changed to sealing ring periphery fitted seal to medium
Carry out sealing.It should be noted that：The sealing structure form of two kinds of above-mentioned telescoping valves, is common, can also adopt other knots
Configuration formula.The advantages of telescoping valve, has：Valve rod bears that medium active force is smaller, and required executing agency is also smaller, can adapt to
Larger bore and pressure difference, shortcoming have：Unreliable to the sealing of medium when closed, leakage rate is larger.
The advantage and disadvantage of both the above valve are opposite mutually.
The reason of we are unreliable to medium-tight to conventional sleeve valve below, and leakage rate is larger is analyzed：It is traditional double
Seat telescoping valve, when closed, it is desirable that two sealing surfaces on two sealing surfaces and sleeve on spool, to form two has foot
The sealing pair of enough seal pressures could carry out medium reliable sealing, since two sealing surface positions respective in two pieces are
It is relatively-stationary, to reach this requirement, the required precision of the position dimension between two sealing surfaces respective on spool and sleeve
Very high, existing level of processing is difficult to reach such required precision, and two sealing pairs are realized in the variation of temperature in addition simultaneously
Reliable sealing also has a great impact, so being extremely difficult to the requirement reliably sealed to media implementation；And single seat telescoping valve is wherein
Sealing ring periphery fitted seal be to form what enough seal pressures were realized by its elastic force, because it can be generated in use
Abrasion, aging and deformation etc., and between increasingly cannot providing enough elastic force and forming enough seal pressures or even can generate
Gap, and cannot be guaranteed reliably to seal media implementation.As can be seen from the above analysis, traditional two seat sleeve valve and single seat telescoping valve
There is respective deficiency to the sealing of medium, cause telescoping valve that there is the shortcomings that sealing is unreliable, and leakage rate is larger.
The reason of only one of traditional shut-off valve sealing structure is its above-mentioned advantage of generation, and balance type structure is to pass through
What two sealed structures were realized, it is not balance type structure, and disadvantages mentioned above can not just overcome；Traditional two seat sleeve valve and single seat
Telescoping valve has two sealed structures, it is balance type structure, is the reason of generating its above-mentioned advantage, but two kinds of telescoping valves are in itself
The disadvantages mentioned above being individually present can not but overcome.Therefore it is never a kind of that there is the above-mentioned of shut-off valve and telescoping valve, gram
Take the valve products of two kinds of valve disadvantages mentioned above.
