Description
BACKGROUND OF THE INVENTION
[0001] Field of the Invention
[0002] The present invention relates to a pressure stabilization
structure, and in particular to a pressure stabilization structure
having a built-in integrally formed booster pump.
[0003] The Prior Arts
[0004] Presently, the design of a pressure stabilization structure
having a booster pump is rather complicated, and its overall
configuration is not efficient and proper. The regulation of
pressure release for high pressure chamber is achieved through the
water pressure itself. The range of regulation realized is narrow,
while its pressure stabilization is insufficient.
[0005] Therefore, presently, the design and performance of the
pressure stabilization structure is not quite satisfactory, and it
leaves much room for improvement.
SUMMARY OF THE INVENTION
[0006] In view of the problems and drawbacks of the prior art, the
present invention provides a pressure stabilization structure
having a built-in integrally formed booster pump, to overcome the
shortcomings of the prior art.
[0007] The present invention provides a pressure stabilization
structure having a built-in integrally formed booster pump,
comprising: a booster pump, a valve body, a high pressure chamber,
and a low pressure chamber. The valve body is formed integrally
with a shell of the booster pump; on the valve body is disposed a
pressure release water input port and a pressure release water
output port; a main valve core is disposed in an inner chamber of
the valve body, that is movable to control the opening size of the
pressure release water output port; and an auxiliary valve core is
disposed in the inner chamber of the valve body, that is
retractable to control the opening size of the pressure release
water input port. The high pressure chamber is disposed on the
booster pump and is connected to a water output end of the booster
pump, and is connected to the pressure release water input port
disposed on the valve body. The low pressure chamber is disposed on
the booster pump, and is connected to the high pressure chamber
through the valve body, the low pressure chamber is connected to
the pressure release water output port disposed on the valve body,
and is connected to a water input end of the booster pump.
[0008] In an aspect of the present invention, the main valve core
includes a pipe piece, that is connected to the inner chamber of
the valve body through threads, and an inner chamber of the pipe
piece is a water flow channel; and a water input end of the pipe
piece is disposed facing the auxiliary valve core, while a water
output end of the pipe piece is disposed facing the pressure
release water output port.
[0009] In another aspect of the present invention, the auxiliary
valve core includes: a spring; and a piston, pressed and connected
on the main valve core. Wherein one end of the spring is fixed in
the inner chamber of the valve body, while one other end of the
spring is fixed in a guiding slot of the piston.
[0010] In a further aspect of the present invention, the pressure
stabilization structure further includes: a tight seal plate,
disposed in a place where the piston is pressed and connected to
the main valve core; and two tight seal rings, disposed between the
piston and the valve body, and between the main valve core and the
valve body.
[0011] Compared with the existing technology, the present invention
has the advantages in that, it is novel in design and structure.
Wherein, outside force is used to regulate the main valve core, to
control the pressure release amount of the piston and the main
valve core, to achieve the pressure required for the high pressure
chamber. When the water pressure at the water input end of the
booster pump is increased, thus the water pressure in the high
pressure chamber is raised, then the piston is opened
automatically, so that the overly high water pressure in the high
pressure chamber is released to the low pressure chamber, to
achieve the stabilized pressure required. In this approach, the
regulation range is increased, the regulation precision is raised,
the overall structure is optimized, while its configuration is more
compact. Further, the valve body and the shell of the booster pump
are made integrally, in achieving high mechanical strength,
superior tight seal, easy maintenance, flexible operation, and high
adaptability.
[0012] Further scope of the applicability of the present invention
will become apparent from the detailed descriptions given
hereinafter. However, it should be understood that the detailed
descriptions and specific examples, while indicating preferred
embodiments of the present invention, are given by way of
illustration only, since various changes and modifications within
the spirit and scope of the present invention will become apparent
to those skilled in the art from this detailed descriptions.
