Technical field
The utility model relates to a kind of spool.
Background technique
Spool is component of valve, and spool is the fundamental function that realizes direction control, pressure control or flow control by moving of it.Existing spool, there are complex structure in for example rubber spool, ceramic valve core, stainless steel spool, axle roll-type spool etc., use the problem of no positioning control.
The model utility content
The purpose of the utility model provides a kind of spool, overcomes the deficiency of above-mentioned aspect in the existing product.
The purpose of the utility model is to realize through following technological scheme:
A kind of spool comprises valve body, and said valve body internal upper part is provided with axle sleeve; Be provided with poppet shaft in the axle sleeve, the axle sleeve bottom is provided with the clamping projection, and the axle sleeve below is provided with fixed base; The fixed base top is provided with the clamping groove that is complementary with said clamping projection, and fixed base is connected with axle sleeve with the clamping projection through the clamping groove, and the fixed base below is provided with spool disk; The spool disk bottom is provided with rectangular recess; The spool disk below is provided with valve gap, and valve gap is provided with first through hole and second through hole, and the orthographic projection of first through hole and second through hole is positioned at rectangular recess.
The inwall of said valve body is provided with first limiting stopper and second limiting stopper, and the central angle between first limiting stopper and second limiting stopper is 90 °, and the outer wall of said axle sleeve is provided with the 3rd limiting stopper, and the 3rd limiting stopper is arranged between first limiting stopper and second limiting stopper.
The outer peripheral edge of said rectangular recess is provided with caulking gum.
The beneficial effect of the utility model is: simple in structure, each parts cooperate rationally, and the spacing design of valve body and axle sleeve makes spool in use convenient.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described spool of the utility model embodiment;
