ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a valve having an inner washing structure, and more particularly to a valve having an inner washing structure, wherein the valve can be washed through the washing hole directly, without having to detach the valve, thereby facilitating the washing work without wearing the inside of the valve.
2. Description of the Related Art
A conventional valve
40
in accordance with the prior art shown in
FIG. 9
comprises a housing
41
defining a hollow receiving chamber
42
which contains a ball
50
which is pivoted with a rotation shaft
43
on the top edge of the housing
41
. The housing
41
of the valve
40
is formed with a washing hole
44
which is located at a position opposite to the center of the ball
50
, and is communicated with the receiving chamber
42
. The housing
41
of the valve
40
is formed with a drain hole
45
which is opposite to the rotation shaft
43
, and is communicated with the receiving chamber
42
.
A beam of washing liquid “W” may be strongly injected into the valve
40
through the washing hole
44
to wash the inside of the valve
40
and the surface of the ball
50
, and may then be drained outward through the drain hole
45
. Then, strongly driven dry air may be injected into the valve
40
through the washing hole
44
to dry the inside of the valve
40
, and may then be drained outward through the drain hole
45
, thereby completing the washing work.
However, the conventional valve has the following disadvantages.
1. The strongly injected washing liquid “W” is directly interrupted by the ball
50
, thereby greatly decreasing the washing effect of the washing liquid “W”.
2. The washing hole
44
directly faces the center position of the ball
50
, so that strongly injected washing liquid “W” will directly touch the surface of the ball
50
, thereby easily scraping or wearing the ball
50
.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional valve.
The primary objective of the present invention is to provide a valve having an inner washing structure, wherein the valve can be washed through the washing hole directly, without having to detach the valve, thereby greatly facilitating the washing work without wearing the inside of the valve.
In accordance with one aspect of the present invention, there is provided a valve having an inner washing structure, the valve having an inside containing a receiving chamber in which a ball is pivoted, so that the ball forms rotation of a single freedom, wherein:
the valve is formed with at least one washing hole which is located at a position in a tangential plane of an outer diameter of the ball, and is communicated with the receiving chamber, the valve has a bottom formed with a drain hole which is located at a position normal to the tangential plane of the outer diameter of the ball and is communicated with the receiving chamber, and each of the washing hole and the drain hole is sealed by a seal.
In accordance with another aspect of the present invention, there is provided a valve having an inner washing structure, the valve having an inside containing a receiving chamber in which a ball is pivoted, so that the ball forms rotation of a single freedom, wherein:
the valve is formed with a first washing hole which is located at a position in a tangential plane of an outer diameter of the ball, and is communicated with the receiving chamber, and the valve is formed with a second washing hole which is located at a position in the tangential plane of the outer diameter of the ball, and is communicated with the receiving chamber, the second washing hole is located opposite to the first washing hole, and each of the first washing hole and the second washing hole is sealed by a seal.
The valve is formed with a third washing hole which is located beside the first washing hole and is communicated with the receiving chamber, and the valve is formed with a fourth washing hole which is opposite to the third washing hole, and is communicated with the receiving chamber.
The valve is formed with a drain hole opposite to the rotation shaft, the drain hole is located at a position normal to the tangential plane of the outer diameter of the ball and is communicated with the receiving chamber.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
