Abstract
The utility model provides a multi -functional super high pressure isolating valve, the case cover is the cylinder, has a perfect understanding about it, and it has the several inlet opening to open on the lateral wall of case cover upper portion, and the case lies in the case cover, side wall of the valve core is last to have the oblique decurrent conical surface of a week for sealing up the face, has two bulges at least in the below of sealed face, be equipped with the depressed part between the adjacent bulge, and the bulge diameter below lieing in is lighter than its top bulge diameter, be equipped with in the case cover to case cover axis direction protruding ring form boss, cyclic annular boss number equals with case bulge quantity that the minimum department of cyclic annular boss top surface tilt up and cyclic annular boss top surface diameter matees rather than the bulge diameter that corresponds, and when the valve was closed, each projecting part do not contacted rather than the cyclic annular boss that corresponds. The utility model discloses a multi stage decompression design has reduced the feed liquor velocity of flow and pressure, has reduced liquid and to sealing erodeing and wearing and tearing of face firmly, has avoided the medium to drop to below the critical pressure, appears the phenomenon of flash distillation cavitation during the answer.
Description
Technical field：
The utility model is related to stop valve technical field, more particularly to a kind of multi-functional ultra-high pressure stopped valve.
Background technology：
Current ultra-high pressure stopped valve, because operting differential pressure is very big, medium is susceptible to flash distillation, cavitation phenomenon, to rear end pipe
Road is damaged, and is repaired and is changed frequent, is also easy to break down.
The content of the invention：
In consideration of it, being necessary to design a kind of multi-functional ultra-high pressure stopped valve of multilevel decompression.
A kind of multi-functional ultra-high pressure stopped valve, valve core housing is cylinder, and its up/down perforation is provided with valve core housing upper portion side wall
Several inlet openings, valve element is single-revolution body, and valve element is located in valve core housing；It is sealing to have one week conical surface obliquely on the wall of valve element side
Face, in the protuberance of the lower section of sealing surface at least two, is provided with depressed part between adjacent tabs, depressed part with its up and down close to
Protuberance between by conical surface transition, and the small protuberance diameter square thereon of underlying protuberance diameter；In valve core housing
It is provided with to valve core housing axis direction projection annular boss, annular boss number is equal with valve element protuberance quantity, annular boss top surface
It is inclined upwardly and protuberance diameter matches corresponding at annular boss top surface diameter minimum, and when valve is closed, it is each convex
Go out portion's annular boss corresponding respectively to be in contact.
Preferably, the annular boss upper surface for immediately having first protuberance, the top under sealing surface is provided with and sealing surface
Coordinate the conical surface.
Preferably, protuberance is three.
The utility model is designed using multilevel decompression, i.e.,：Medium is accessed in valve chamber, need to just can be with by multilevel decompression
Outflow valve body cavity, the three-level throttle structure of spool mechanism is effectively reduced into flow velocity and pressure, reduces liquid to hard sealing
Face is washed away and is worn and torn, it is to avoid medium drops to below critical pressure, the phenomenon for occurring flash distillation cavitation when pressure recovers.In addition,
Medium flow direction uses high in and low out, and valve rod overstriking, out-of-balance force is small, and pressure becomes big, and seal pressure becomes big, so as to ensure that valve exists
In the state of high pressure-temperature, zero leakage is reached.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of the multi-functional ultra-high pressure stopped valve of a width better embodiment.
Accompanying drawing 2 is the structural representation of the multi-functional ultra-high pressure stopped valve core set of a width better embodiment.
Accompanying drawing 3 is the structural representation of the multi-functional ultra-high pressure stopped valve core of a width better embodiment.
In figure：Valve core housing 1, valve body 2, inlet opening 11, enter medium runner 21, go out medium runner 22, valve element 3, close
Front cover 31, protuberance 32, depressed part 33, annular boss 12.
Specific embodiment：
As shown in accompanying drawing 1~3, a kind of multi-functional ultra-high pressure stopped valve, using the structure of upper entering and lower leaving, valve core housing 1 is fixed
In the cavity of valve body 2, valve core housing 1 is cylinder, and its up/down perforation is provided with several inlet openings 11 in the upper portion side wall of valve core housing 1,
The UNICOM of medium runner 21 is entered in inlet opening 11 with valve body 2, and the bottom of valve core housing 1 goes out the UNICOM of medium runner 22, valve element 3 with valve body 2
It is single-revolution body, valve element 3 is located in valve core housing 1；There is one week conical surface obliquely on the side wall of valve element 3 for sealing surface 31, in sealing
The protuberance 32 of the lower section in face 31 at least two, is provided with depressed part 33 between adjacent tabs 32, depressed part 33 is tight up and down with it
By conical surface transition between adjacent protuberance 32, and the small diameter of protuberance 32 square thereon of the diameter of underlying protuberance 32；
It is provided with valve core housing 1 to the axis direction of valve core housing 1 projection annular boss 12, the number of annular boss 12 and the quantity of 3 protuberance of valve element 32
Equal, the top surface of annular boss 12 is inclined upwardly and the diameter of protuberance 32 corresponding at the top surface diameter of annular boss 12 minimum
Match somebody with somebody, and when valve is closed, the annular boss 12 corresponding respectively of each protuberance 32 is in contact.
In the present embodiment, immediately there are first protuberance 32, the upper table of annular boss 12 of the top under sealing surface 31
Face is provided with and coordinates the conical surface with sealing surface 31.Protuberance 32 is three.
