Description
Technical field
The utility model relates to valve technology field, especially a kind of structure novel, the double containment peculiar to vessel of good seal are straight
Angle check valve.
Background technique
Traditional check-valves is usually flat stifled formula structure, and the material of check-valves is mainly cast iron.Existing check-valves is usual
The disadvantages of that there are valve volumes is larger, intensity is not high, poorly sealed, intolerant to abrasion, easy to leak, and service life is short.Currently, existing
The flat stifled formula structure of check-valves is easy in pollutants such as the upper surface accumulation sludge of partition, and long-term switch operation can be to sealing surface
It causes to wear, to reduce the sealing performance of check-valves, causes to leak.
Utility model content
The purpose of the utility model is to provide a kind of compact-sized, good seal, the longer angle check valves of service life.
The purpose of this utility model is achieved by the following technical solution:
Double-sealing right angle check-valves peculiar to vessel, including valve body and valve deck, valve body are equipped with inlet and outlet, and valve deck and valve body connect
It connects, valve deck is located at valve body upper end, and guide sleeve is arranged below in valve deck, and guide sleeve lower end is equipped with valve disc, and valve disc is set in guide sleeve
It can move up and down on guide rod and along guide rod, the lower end surface of the valve disc is set as the spherical structure of evagination, the valve body
It is equipped with partition between import and outlet, is provided with through-hole on partition；The partition upper surface is equipped with and matches with valve disc lower end spherical surface
Spherical concave surface, the spherical surface of the valve disc lower end and the concave surface of partition can form connection in sealing contact, and keep the through-hole close
Envelope.
As the optimal technical scheme of the utility model, the partition upper surface is equipped with annular seal groove, sets in seal groove
It is equipped with the first sealing ring.
As the optimal technical scheme of the utility model, the upper end of the guide sleeve is equipped with annular edge, and annular edge is located at institute
It states between valve deck and the upper surface of valve body.
It is close that second is additionally provided with as the optimal technical scheme of the utility model, between the annular edge and the upper surface of valve body
Seal.
As the optimal technical scheme of the utility model, the axis of the axis of the valve body import perpendicular to valve outlet.
As the optimal technical scheme of the utility model, the valve body and valve deck are processed by cast steel, the guiding
Set and valve disc are processed by bronze.
The beneficial effects of the utility model are: compared with the existing technology, the utility model flat stifled formula that check-valves is traditional
Structure is improved to spherical structure, effectively reduces the pollutant of partition upper surface accumulation, long-term switch operation will not be to sealing
Face causes to wear, and is provided with Double seal ring structure, avoids leaking, to significantly extend the sealing performance of check-valves and make
Use the service life.The utility model is compact-sized, intensity is higher, and good seal, the service life is longer.
