The technique that exists is not enough to the aforesaid, the utility model aims at providing a novel boiler governing valve, through the compressing valve seat under the effect of axial tension, make disk seat and squirrel cage become a relative whole, sealed and protection case that can be better, the operation and maintenance of being convenient for, and do not change the working method of governing valve, leak the defect in having eliminated the valve, the life of extension valve.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a novel boiler regulating valve is characterized by comprising a valve seat, a sealing pressure ring, a squirrel cage and a valve core; a stepped groove is formed in the valve seat; the sealing pressure ring is movably sleeved on the stepped groove; the front end of the squirrel cage is provided with an inner ring groove matched with the stepped groove and an outer ring groove matched with the sealing compression ring; the squirrel cage is movably sleeved on the stepped groove through an inner annular groove, and the sealing press ring is movably sleeved on the outer annular groove; the valve core is movably arranged in the squirrel cage.
The beneficial effects of the utility model reside in that: the utility model provides a design, through the tight disk seat of the effect of axial tension down, make disk seat and squirrel cage become a relative whole, sealed and protection case that can be better, the operation and maintenance of being convenient for, and the operational mode that does not change the governing valve has eliminated the interior defect that leaks of valve, the life of extension valve.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It should be noted that in the description of the present invention, the terms "in", "up", "down", "horizontal", "inner", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1, the novel boiler regulating valve comprises a valve seat 2, a sealing pressure ring 1, a squirrel cage 4 and a valve core 5; a stepped groove 3 is arranged on the valve seat 2; the sealing compression ring 1 is movably sleeved on the stepped groove 3; the front end of the squirrel cage 4 is provided with an inner ring groove matched with the stepped groove 3 and an outer ring groove matched with the sealing press ring 1; the squirrel cage 4 is movably sleeved on the stepped groove 3 through the inner annular groove, and the sealing press ring 1 is movably sleeved on the outer annular groove; the valve core 5 is movably arranged in the squirrel cage 4, the valve seat 2, the sealing press ring 1 and the squirrel cage 4 are fixedly connected in a pressing force positioning mode of the squirrel cage 4, and the size of the sealing press ring 1 can compensate the axial clearance between the stepped groove 3 of the valve seat 2 and the outer annular groove of the squirrel cage 4.
The specific embodiment is as follows:
1. and (5) inspecting the sealing surfaces of the valve core 5 and the valve body, and grinding the sealing surfaces if the valve core and the valve body are worn.
2. Design of a new sealing ring 1
The depth L of the ground valve seat 2, the height H of the valve seat 2, the small diameter (namely the small diameter of the external thread of the original sealing compression ring 1) d of the internal thread of the valve body, the height L of the squirrel cage 4, the thickness S of the sealing gasket of the valve cover and the height H of the step of the valve cover are measured. According to the size of grinding back valve body seal chamber degree of depth, disk seat 2 and squirrel cage 4, the thickness of metal winding pad and the overall dimension of middle sealed clamping ring 1 of compressive capacity determination, guarantee that the height of disk seat 2+ sealed clamping ring 1+ squirrel cage 4 equals the height of valve body seal chamber just under the condition of not adding sealed pad, promptly:
the new sealing pressure ring 1 has the height x of L + S-H-L-H
The new sealing press ring 1 design ensures that the tightening force of the bolt is completely converted into the compression amount of the winding pad after the valve is reinstalled.
3. And adjusting the sealing gasket. For more accurate valve body axial positioning, this project adopts high-pressure metal to twine the pad (every thickness 3.5mm) sealed, and three piece twine the total compression volume of pad and can reach 4mm, and great compression volume has not only guaranteed valve gap boss compression depth, compensates again because grind and causes the unhevel error of valve body sealing face, has both solved the valve seat 2 when the valve repacking location problem and has further strengthened the sealing performance of valve.
4. And (5) processing the sealing compression ring 1. As the medium used by the valve is high temperature and high pressure, the 310S bar is selected for processing in order to ensure the strength of the sealing pressure ring 1.
5. And after the sealed pressure ring 1 is processed and the sizes are checked to be correct, the sealed pressure ring is installed again in sequence. In order to prevent the valve cover from sealing leakage and the valve core 5 from being positioned, the depth (not less than 5mm) of the boss pressed into the sealing chamber of the valve cover is taken into consideration when the valve is assembled again.
The utility model provides a design, through the tight disk seat of the effect of axial tension down, make disk seat and squirrel cage become a relative whole, sealed and protection case that can be better, the operation and maintenance of being convenient for, and the operational mode that does not change the governing valve has eliminated the interior defect that leaks of valve, the life of extension valve.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
