Abstract
The utility model provides a quick water connector structure of a rolling machine frame, which can avoid the valve core seizing-up phenomenon during the use and has good leak tightness and a long service life. The quick water connector structure of the rolling machine frame comprises a valve casing formed by connecting a connector and a sleeve, wherein a T-shaped valve core is buckled in the valve casing. The quick water connector structure of the rolling machine frame is characterized in that a cavity is formed by the rod part of the T-shaped valve core and the valve casing, a spring is arranged in the cavity, the two ends of the spring are respectively propped against the bonding surfaces of the valve core and the valve casing which are buckled with each other, the head part of the valve core is hollow and the tail part of the valve core is a blind end, a through hole is formed on the body of the valve core and at the tail part of the valve core, the tail end of the valve core is sleeved with a gasket nut, and on the condition that the valve core is reset, the gasket nut is jointed with the end part of the sleeve and the through hole is positioned inside the valve casing.
Description
Technical field
The utility model relates in the seamless mandrel mill-rolled steel pipe production line, and rolling machine frame roll surface cooling water flusher is specially the quick water swivel structure of rolling machine frame.
Background technology
In seamless mandrel mill-rolled steel pipe production line, the service life of the sprinkling breaker roll of cooling water is of crucial importance.At present, the material of spool, joint and cover that the water swivel structure of existing rolling machine frame is used is identical, and in use, spool is stuck easily, and sealing is poor, and service life is short.
Summary of the invention
To there being above-mentioned shortcoming in the prior art, the utility model provides the quick water swivel structure of rolling machine frame, and it can avoid spool stuck phenomenon in use, good airproof performance, long service life.
Its technical scheme is such, and it comprises the valve casing that is formed by joint, cover connection, and spiral-lock has T type spool in the said valve casing; It is characterized in that: the bar portion and the said valve casing of said T type spool surround cavity, are provided with spring in the said cavity, the two ends difference said spool of roof pressure of said spring and the faying face of valve casing spiral-lock; The head hollow of said spool, the afterbody of said spool are cecum, at the afterbody of said spool; The body of said spool is provided with through hole, and the tail end of said spool is set with washer nut, under the condition of said valve core reset; Fit in the end of said washer nut and said cover, said through hole is positioned at the inside of said valve casing.
It is further characterized in that: the junction of said spool and said valve casing is provided with sealing ring.
The utility model adopts after the said structure, makes time spent promotion spool as external force and moves backward, and the limbers of spool afterbody communicates with cooling water; Cooling water is sprayed to roller surface; When there not being external force to do the time spent, spool is because the effect of spring resets, and this moment, washer nut was sealed the outlet pass of spool afterbody; Realize quick closedown, the spool stuck phenomenon is less in the use; And sealing ring is set in joint body rear and front end, the cover front end is provided with sealing ring, all plays good sealing effectiveness, has further guaranteed the phenomenon that less appearance is stuck, has guaranteed the service life of the quick water swivel device of rolling machine frame.
Description of drawings
Fig. 1 is the axial cutaway view under the utility model open and close two states.
The specific embodiment
See Fig. 1, the utility model comprises joint 1, cover 5 valve casings that are formed by connecting, and joint 1 and cover 5 link together through fastening bolt; Spiral-lock has T type spool 2 in the valve casing, and the root and the valve casing of T type spool 2 surround cavity, are provided with spring 4 in the cavity; The faying face of roof pressure spool 2 and valve casing spiral-lock is distinguished at the two ends of spring 4, promptly overlaps the annulus wall of 5 inwalls, the head hollow of spool 2; The afterbody of spool 2 is a cecum, and at the afterbody of spool 2, the body of spool 2 is provided with through hole 7; The tail end of spool 2 is set with washer nut 6, and under the condition that spool 2 resets, fit in the end of washer nut 6 and cover; Through hole 7 is positioned at the inside of valve casing, and the junction of spool 2 and valve casing is provided with sealing ring 3.Joint 1 body rear and front end inwall has seal groove, and sealing ring 3 places in the seal groove, and spool 2 is processed by nylon, overlaps 5 front inner wall and has seal groove; Sealing ring 3 places in the seal groove, does the time spent as external force, promotes spool 2 and moves backward; The limbers 7 of spool 2 afterbodys communicates with cooling water, and cooling water is sprayed to roller surface, when there not being external force to do the time spent; Spool 2 is because the effect of spring 4 resets, and this moment, washer nut 6 was sealed the outlet pass of spool 2 afterbodys, realized quick closedown.
Claims (2)
1. the quick water swivel structure of rolling machine frame, it comprises by joint, cover and connects the valve casing that forms that spiral-lock has T type spool in the said valve casing; It is characterized in that: the bar portion and the said valve casing of said T type spool surround cavity, are provided with spring in the said cavity, the two ends difference said spool of roof pressure of said spring and the faying face of valve casing spiral-lock; The head hollow of said spool, the afterbody of said spool are cecum, at the afterbody of said spool; The body of said spool is provided with through hole, and the tail end of said spool is set with washer nut, under the condition of said valve core reset; Fit in the end of said washer nut and said cover, said through hole is positioned at the inside of said valve casing.
