Abstract
This utility model relates to a kind of waste heat boiler three spheres from centering spool.Including the valve core rod (5) being connected and sphere core (1), the valve core head (3) of this valve core rod (5) is respectively equipped with rod head end sphere and backside sphere, it is characterized in: in the spool groove at described sphere core (1) back side, be installed with one piece of sphere top board (2), and the rod head end sphere of described valve core head (3) gos deep in this spool groove, and the top of the rod head end sphere of this valve core head (3) contacts with aforesaid sphere top board (2) and leaves gap between its side and spool groove.Test proves that, after using three sphere contact type structures of the present utility model, valve core rod and sphere top board are possible not only to relative circumferential and rotate, and when spool contacts with valve seat, thrust by actuator can also realize the transverse shifting of valve core head, greatly adds the adjustable extent of valve core head.
Description
Technical field
This utility model relates to a kind of waste heat boiler three spheres from centering spool.
Background technology
Fire tube waste heat boiler is provided with the larger diameter center pipe passed through for hot process gases, in
Heart pipe exit is provided with the valve of regulation flow, and owing to outlet temperature is the highest, butterfly valve easily blocks
Extremely, employed the regulation valve with sphere core in the last few years, but the tune that great majority are horizontally mounted
For joint valve, diameter and the excessive valve core head of quality can cause the valve rod worked under hot environment easily to become
Shape, makes spool and sealing surface of seat deviation, it is difficult to meet regulation valve to central canal outlet process gas stream
The control of amount and regulation effect, can not accurately control hot process gases outlet temperature, therefore can lead
Cause long-term work regulation valve in high temperature environments to be greatly shortened service life, in order to meet production need
Want, often have to replace too early valve, owing to such valve material is special, expensive, so
The operating cost of equipment can be greatly increased.
Utility model content
The purpose of this utility model is to provide a kind of waste heat boiler three spheres from centering spool, it is possible to more
Mend because the spool caused by valve rod deformation the most to a certain extent and valve seat can not be right
Positive defect, thus extend the service life of valve.
A kind of waste heat boiler with three spheres from centering spool, including the valve core rod being connected and spherical valve
Core, is respectively equipped with rod head end sphere and backside sphere, its special feature on the valve core head of this valve core rod
It is: in the spool groove at the described sphere core back side, be installed with one piece of sphere top board, and institute
The rod head end sphere stating valve core head gos deep in this spool groove, and the rod head end sphere of this valve core head
Top and aforesaid sphere top plate contact and leave gap between its side and spool groove.
The most also including spool pressing plate, this spool pressing plate is fixedly mounted on sphere core, and this valve
The backside sphere-contact of the inwall of core pressing plate and valve core head thus by valve core rod and sphere core activity even
It is connected together.
Wherein on the inwall of spool pressing plate be arc-shaped at the backside sphere-contact of valve core head.
Test proves that, after using three sphere contact type structures of the present utility model, valve core rod and ball
Face top board is possible not only to relative circumferential and rotates, and when spool contacts with valve seat, the thrust by actuator also may be used
To realize the transverse shifting of valve core head, greatly add the adjustable extent of valve core head.Additionally spool
Bar and valve core head groove leave regulation gap, can meet the regulation degree of freedom of valve core head greatly.Adopt
With waste heat boiler of the present utility model three spheres from centering spool, have the strongest from centering ability,
Valve rod can well be overcome to deform the problem brought to a certain extent, improve the use longevity of valve
Life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model relates to a kind of waste heat boiler three spheres from centering spool, bag
Include the valve core rod 5 (valve rod) and sphere core 1 being connected, on the valve core head 3 of this valve core rod 5
It is respectively equipped with rod head end sphere and backside sphere, solid in the spool groove at described sphere core 1 back side
Dingan County is equipped with one piece of sphere top board 2, and the rod head end sphere of described valve core head 3 gos deep into this spool groove
In, and the top of the rod head end sphere of this valve core head 3 contacts and its side with aforesaid sphere top board 2
Gap is left between end and spool groove.
The most also including spool pressing plate 4, this spool pressing plate 4 is fixedly mounted on sphere core 1, and
And the backside sphere-contact of the inwall of this spool pressing plate 4 and valve core head 3 thus by valve core rod 5 and sphere
Spool 1 is movably connected, and on the inwall of spool pressing plate 4 with the backside sphere of valve core head 3
Contact position is arc-shaped.
Embodiment 1:
It is illustrated in figure 1 three spheres of the present utility model to do loss of weight set from centering spool, sphere core 1
Meter, coordinates equipped with one piece of sphere top board 2 in spool groove, leaves between valve core rod 5 and spool groove
Regulation gap, valve core rod 5 (the rod head end sphere (i.e. lower surface) of valve core head 3 and sphere top board 2
Contact, can realize circular-rotation and tiny transverse movement regulation, backside sphere (i.e. upper surface) and valve
Taper-face contact on core pressing plate 4 inwall, is designed with groove on spool pressing plate 4, convex with valve core head 3
Platform coordinates to be installed, with hexagon-headed bolt fixed spool pressing plate 4 position.
During installation, first the hexagon-headed bolt on spool pressing plate 4 is unclamped, treat that valve core head 3 is looked for valve seat
After just, spool pressing plate 4 is installed on valve core head 3 boss, after making valve core rod 5 capturing position, then
Turret head screwing up stud is fixed.
Using live body to connect in this utility model between valve core head 3 and valve core rod 5, spool does loss of weight and sets
Meter, has deeper groove in valve core head 3, coordinate one piece of sphere top board 2 in groove, valve core rod 5
Head (valve core head 3) does double spherical design, and can put in valve core head 3 groove, head and groove
Between leave regulation gap, utilize conical surface spool pressing plate 4 between valve core head 3 and double spherical valve core bar 5
It is fixed.Have and suffer from one's own actions orthofunction with valve seat, it is possible to achieve circular-rotation and the regulation of transverse shifting
Mode, activity space is big, and centering ability is strong, solves to deform in high temperature environments because of valve core rod 5 and draws
The core print seat skew problem risen, alleviates the nose heave amount of valve core, prevents valve core rod 5 premature deformations, improves valve
Service life.
