Journey complexity is spent, cost absorbing and benefit is not ideal enough.
Utility model content
The purpose of this utility model is to provide for a kind of compression type guide frame, passes through guide sleeve and valve deck separate structure
Setting, solve the problems, such as integral type valve deck processing when the bad guarantee of concentricity, also solve because temperature change causes to be oriented to
The problem of set falls off, substantially increases the applicability of valve；Guide sleeve and valve cage are precision castings simultaneously, simplify processing technology,
It is high to assemble first-time qualification rate, improves production capacity and economic benefit.
In order to achieve the above object, the utility model provides following technical solution: a kind of compression type guide frame, including
Valve body, valve deck, filling body, mounting rack, executing agency, valve rod, spool, valve seat, valve cage and guide sleeve, the valve body, valve deck,
Mounting rack and executing agency are sequentially connected from the bottom to top, and the upper end of the valve rod connects executing agency, and lower end passes through valve deck, valve body
It is connected in the spool of inner cavity on valve body afterwards, the filling body is set between valve deck and valve rod, the valve cage and guiding
Set is pressed abd fixed between valve seat and valve deck, and the guide sleeve includes that the positioning plane, the guide surface of bottom, connection at top are fixed
The center of the interconnecting piece of bit plane and guide surface, the guide surface is equipped with pilot hole.
It is further preferred that the bottom of the valve deck is equipped with the first positioning ring groove of corresponding positioning planar top.
It is further preferred that the outer fringe position of the positioning plane upper and lower sides is equipped with assembly chamfer.
It is further preferred that the top of the valve cage is equipped with the second positioning ring groove of corresponding positioning planar base.
It is further preferred that the stop collar that the top of the valve seat is equipped with corresponding valve cage bottom is raised, and valve cage bottom
Internal diameter is greater than the outer diameter of stop collar protrusion.
It is further preferred that the upside of the positioning plane is equipped with the first heat-insulated annular groove, set in the first heat-insulated annular groove
There is the first heat insulating metal ring, the upside of the guide surface is equipped with the second heat-insulated annular groove, and the is equipped in the second heat-insulated annular groove
Two heat insulating metal rings.
The utility model has the beneficial effects that passing through the setting of guide sleeve and valve deck separate structure, solves integral type valve deck
When processing the problem of concentricity bad guarantee, also solves the problems, such as to cause guide sleeve to fall off because of temperature change, substantially increase
The applicability of valve can also be influenced to avoid the matching of valve rod and guide sleeve by temperature, guarantee valve working performance；Simultaneously
Guide sleeve and valve cage are precision castings, simplify processing technology, and assembling first-time qualification rate is high, improves production capacity and economic benefit.

Specific embodiment
We are described further a kind of compression type guide frame described in the utility model in conjunction with attached drawing below.
Embodiment one
As shown in Fig. 1 to Fig. 5, a kind of compression type guide frame, including valve body 1, valve deck 2, filling body 3, mounting rack
