ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a distribution valve, and more particularly to a locating structure of the distribution valve.
2. Description of Related Art
As shown in
FIG. 1
, a distribution valve
10
of the prior art has a tubular body
11
which is provided with a fitting tube
12
in communication with the hollow interior of the tubular body
11
. The fitting tube
12
is provided at the top end with a cut
13
. A ball valve
14
has a bolt body
15
. The ball valve
14
is disposed in the hollow interior of the tubular body
11
such that the bolt body
15
is received in the fitting tube
12
. A rotary knob
16
is provided at one end with a pillar
17
, which is received in the fitting tube
12
such that the pillar
17
is fastened to the bolt body
15
of the ball valve
14
by a fastening screw
18
, and such that a protruded block
19
of the rotary knob
16
is rested on the cut
13
of the fitting tube
12
. The ball valve
14
is actuated to turn in the tubular body
11
by the rotary knob
16
. The rotation of the rotary knob
16
is confined by the protruded block
19
and the cut
13
.
The distribution valve
10
of the prior art is defective in design because the installation of the ball valve
14
in the interior of the tubular body
11
is different and rather time-consuming in view of the combined diameter of the ball valve
14
and the bolt body
15
being greater than the inner diameter of the tubular body
11
. In addition, the bolt body
15
of the ball valve
14
is fastened to the rotary knob
16
by the fastening screw
18
, which is apt to loosen so as to result in separation of the protruded block
19
from the cut
13
of the fitting tube
12
. As a result, the ball valve
14
cannot be positioned by the rotary knob
16
.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a distribution valve with a locating structure free from the deficiencies of the prior art distribution valve described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a distribution valve comprising a tubular body, a fitting tube, a rotating body, a handle, and a spherical body. The spherical body is rotatably disposed in the interior of the tubular body such that the spherical body is located by the handle via the rotating body which is fastened at one end to the handle, and is engaged at other end to the spherical body.
