Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged schematic view of a portion of the structure of fig. 1 according to the present invention;

the reference numerals are explained below:

1. the quick-mounting type hydraulic control valve comprises a valve core, a 2 conversion sleeve, a 3 valve nozzle, a 4 conversion shaft, a 5 compression spring, a 6 valve rod, a 7 valve seat, a 8 end cover, a 9 guide plate, a 10 upright post, a 11 cylindrical spiral compression spring, a 12 cylinder fixing plate, a 13 adjustable cylinder, a 14C-shaped oil seal, a 15 guide ring, a 16 guide wing, a 17 quick-mounting clamp;

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the filling valve includes a valve seat 7 and a valve nozzle 3 which are detachably connected, an adjustable cylinder 13 is arranged at the top end of the valve seat 7, the lower end of the adjustable cylinder 13 is fixed on an end cover 8, and the end cover 8 is fixedly connected with the valve seat 7; an upright post 10 is arranged around the end cover 8, the upright post is connected with an upper cylinder fixing plate 12, and the upper part of the adjustable cylinder 13 is connected with a cylinder fixing plate; the adjustable cylinder is linked with a valve rod 6 positioned in a valve seat, the bottom of the valve rod 6 is connected with a valve core 1 positioned in a valve nozzle 3, a guide wing 16 and a conversion shaft 4 matched with the guide wing to form a cavity for accommodating a pressure spring 5 are arranged on the outer side of the valve rod 6 positioned in the valve seat 7, the lower part of the conversion shaft 4 is connected with a conversion sleeve 2, and a certain distance is reserved between the conversion sleeve 2 and the valve core 1;

when the oil quantity reaches a close value, the valve core is pressed downwards through the conversion shaft, the area of an oil outlet is reduced, the oil flow speed is further reduced, when the requirement is met, the adjustable air cylinder is controlled to continuously apply pressure downwards, and the valve rod is driven to press the valve core to the lowest end closed oil outlet through the conversion shaft.

In a specific embodiment, a cylindrical helical compression spring 11 is arranged on the outer side of the output shaft of the adjustable air cylinder 13, and the bottom end of the cylindrical helical compression spring 11 is fixed on the guide plate 9;
