Abstract
The utility model discloses a valve plug sealing installation mold of a descaling injection valve, which comprises a localizer, the outer surface of the localizer is a tapered table structure, and thediameter of the big head of the tapered table structure of the localizer is equal to the diameter of the valve plug; when the valve plug sealing installation mold of the descaling injection valve isused, the valve plug is made upright, the big head of the tapered table structure is made opposite to the end surface of the valve plug, a sealing ring is sleeved at the outer conical surface of the localizer, the downward force is exerted to make the sealing ring be easily sleeved at the valve plug, the installing operation is simple and convenient, the installing time can be greatly shortened, the working efficiency is increased, and the damage to the sealing ring can not be generated during the installing course, the sealing effect of the sealing ring can be effectively ensured, the servicelife of the sealing ring is extended, and the use cost and the maintenance cost are reduced.
Description
Technical field
The utility model relates to a kind of de-scaling injection valve spool laser diode attachment auxiliary, particularly a kind of de-scaling injection valve seal spool installation mold.
Background technology
The de-scaling injection valve is used for high-pressure water descaling system, is installed on the pipeline that medium is a water, mainly works to remove steel plate or billet surface oxide skin.Injection valve mainly comprises valve seat, spool and relative drive systems, and spool is a cylindrical structural, and cannelure along the circumferential direction is set, and the wear-resistant seal circle is set in the cannelure, moves back and forth with spool, and guarantees axial seal.Because the medium of injection valve is a water under high pressure, thereby the mechanical performance of sealing ring had relatively high expectations, need preferably wearability, elasticity and have mechanical strength preferably, guaranteeing the excellent sealing of injection valve, thereby to such an extent as to guarantee the operate as normal of injection valve whole system.
In the prior art, for guaranteeing the good fit of sealing ring and spool, internal diameter of the seal ring generally all is slightly less than spool cannelure diameter, thereby the installation of sealing ring is comparatively difficult, and mounting means is tradition comparatively, and not only the set-up time is long, inefficiency, also can cause damage, influence the service life of sealing ring, cause the raising of the cost of overhaul sealing ring.
Therefore, need the mounting means of existing injection valve core seal ring be improved, can shorten the set-up time greatly, increase work efficiency, and can not cause damage in the installation process to sealing ring, can effectively guarantee the sealing effectiveness of sealing ring, prolong the service life of sealing ring, reduce and use and maintenance cost.
The utility model content
In view of this, the utility model provides a kind of de-scaling injection valve seal spool installation mold, be used for installing the injection valve core seal ring, fitting operation is simple and convenient, can shorten the set-up time greatly, increases work efficiency, and can not cause damage in the installation process to sealing ring, can effectively guarantee the sealing effectiveness of sealing ring, prolong the service life of sealing ring, reduce and use and maintenance cost.
De-scaling injection valve seal spool installation mold of the present utility model comprises locator, and described locator outer surface is a circular cone structure, and the diameter at butt end of locator circular cone structure equates with valve core diameter.
Further, also comprise the installing sleeve that is enclosed within the locator cylindrical, described installing sleeve inner surface is a circular cone structure, the circular cone structure tapering of described installing sleeve inner surface is identical with the tapering of locator circular cone structure, and circle major part end diameter equals locator cylindrical major part end diameter in the installing sleeve;
Further, the tapering of described locator circular cone structure is 1: 10;
Further, described installing sleeve cylindrical is cylindrical.
The beneficial effects of the utility model: de-scaling injection valve seal spool installation mold of the present utility model, adopting outer surface is the locator of circular cone structure, and the diameter at butt end of locator circular cone structure equates with valve core diameter, during use that spool is upright, the major part of circular cone structure is relative with spool end, sealing ring is enclosed within the locator outer conical surface, apply downward power, make more or less freely being enclosed within on the spool of sealing ring, fitting operation is simple and convenient, can shorten the set-up time greatly, increase work efficiency, and can not cause damage in the installation process, can effectively guarantee the sealing effectiveness of sealing ring sealing ring, prolong the service life of sealing ring, reduce and use and maintenance cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the de-scaling injection valve seal spool installation mold of present embodiment, comprise locator 1, described locator 1 outer surface is a circular cone structure, the diameter at butt end of locator circular cone structure equates that with valve core diameter in the present embodiment, the tapering of locator circular cone structure is 1: 10, be beneficial to the slip of sealing ring, do not cause ring wear.
In the present embodiment, also comprise the installing sleeve 2 that is enclosed within locator 1 cylindrical, described installing sleeve 2 inner surfaces are circular cone structure, the circular cone structure tapering of described installing sleeve 2 inner surfaces is identical with the tapering of locator circular cone structure, and circle major part end diameter equals locator 1 cylindrical major part end diameter in the installing sleeve 2; During use sealing ring 3 is enclosed within the stub end of locator 1, with installing sleeve 2 vertically stub end move that (spool 4 is upright, locator 1 major part and spool 4 upper ends align, thereby installing sleeve moves down the direction of arrow among the figure), sealing ring 3 integral body are shifted onto on the spool 4, installation process is simple and convenient, installation process is stressed evenly not only saves the set-up time, can also guarantee that sealing ring is not damaged.
In the present embodiment, installing sleeve 2 cylindricals are cylindrical, are beneficial to and apply downward installing force, improve installation effectiveness.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
