Description
Technical field
The present invention relates to valve technology field, especially a kind of structure novel, good seal double-sealing right angle peculiar to vessel stop
Return 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.
Summary of the invention
The object of the present invention is to provide a kind of compact-sized, good seal, the longer angle check valves of service life.
The purpose of the present invention is what is realized by using following technical scheme:
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 preferred technical solution of the present invention, the partition upper surface is equipped with annular seal groove, is provided in seal groove
First sealing ring.
As the preferred technical solution of the present invention, the upper end of the guide sleeve is equipped with annular edge, and annular edge is located at the valve
Between lid and the upper surface of valve body.
As the preferred technical solution of the present invention, the second sealing is additionally provided between the annular edge and the upper surface of valve body
Circle.
As the preferred technical solution of the present invention, the axis of the axis of the valve body import perpendicular to valve outlet.
As the preferred technical solution of the present invention, the valve body and valve deck are processed by cast steel, the guide sleeve and
Valve disc is processed by bronze.
The beneficial effects of the present invention are: compared with the existing technology, the present invention improves the traditional flat stifled formula structure of check-valves
For spherical structure, the pollutant of partition upper surface accumulation is effectively reduced, long-term switch operation will not cause to grind to sealing surface
Damage, and it is provided with Double seal ring structure, it avoids leaking, to significantly extend the sealing performance and service life of check-valves.
Structure of the invention is compact, intensity is higher, and good seal, the service life is longer.
