FIG. 1
The present invention relates to the technical field of pressure reducing valves, and more
particular, to a novel low-pressure gas pressure reducing valve.
Pressure reducing valves as home gas appliance fittings are important gas apparatus
mounted on an angle valve of a liquefied gas steel cylinder to connect the angle valve and a
rubber pipe, functioning to reduce and stabilize an output pressure. Pressure reducing valves
have advantages of simple structure, stable pressure, light weight, convenience for adjusting
and mounting, and so on. Current pressure reducing valves are typically composed of a gas
inlet, a gas outlet, a handwheel, an upper valve cover, a lower valve cover, a gas intake
nozzle, a breathing hole, an upper gas chamber, a pressure reducing chamber, a valve pad, a
lever, a rubber film, a spring, an adjusting plug and other components. Prior pressure
reducing valves have a simple structure, and often lack a protection device when in use,
failing to detect gas leakage in time, which results in damage to property and injury to
persons.
1. The Technical Problem to be Resolved
With respect to the problems existing in the prior art, an objective of the present
invention is to provide a novel low-pressure gas pressure reducing valve. When in use, a gas valve can be easily fixedly mounted to a position of use by mounting fastening bolts in through holes, and a rubber cushion layer and a buffer spring in a buffer block cooperate to perform functions of shock absorption and buffering at the same time when in use, thereby increasing a service life of the gas value. A connection mechanism is disposed, so that when in use, a threaded layer inside a pipe sleeve is threadedly connected to a gas pipeline, thereby making pipeline interconnection more convenient. A threaded connection portion can be better protected by disposing a protection ring sleeve, which prevents the connection portion from leaking gas as a result of damage through long-term use. while safety hazards caused by gas leakage can be prevented during connection of the valve by disposing a sealing cushion ring. A safety mechanism is disposed, so that when in use, when a temperature at the outer side of the gas valve is excessively high, a temperature sensor senses a signal at this time, a digital signal processor (DSP) controller first controls the buzzer to send an alarm, then the signal is transmitted by a signal transmitter to remotely notify an alarm. When the gas leaks, a gas sensor senses a signal, and the DSP controller controls operation of a electromagnetic valve. In response, the electromagnetic valve is closed to cut off gas supply, and then an alarm device produces an alarm. A gas pressure gauge is disposed to observe an internal gas pressure at all times, thereby reducing a possibility of fire. An adjusting bolt can be rotated as needed by disposing a pressure regulating mechanism. The adjusting bolt rotates inside a connection port to enable a sealing pressing block to press against a pressure spring to further increase the tension of the pressure spring, thereby increasing a pressure and performing a function of adjusting the pressure. Moreover, the inside of the connection port can be better sealed by disposing a sealing ring to further prevent gas leakage. When a gas valve body runs, the gas enters into a pressure reducing cavity through a nozzle hole to enable a central diaphragm shaft to lift an equalizer lever. Since the pressure spring applies a certain pressure, a diaphragm assembly and the equalizer lever mutually expand to enable the equalizer lever to close the nozzle hole, and it is in a closed position at this time. After a user opens the gas stove, the pressure spring interacts with the diaphragm assembly and the equalizer lever at this time to enable the gas to reach a required pressure. The equalizer lever opens the nozzle hole. By means of such repeated adjusting processes, the internal pressure of the pressure reducing cavity is enabled to maintain a constant state, so that the pressure at a gas outlet end is stable regardless of whether an intake pressure is excessively high or excessively low, thereby performing the function of reducing and stabilizing the pressure.

3. Advantages
Compared with the prior art, the present invention has the following advantages.
(1) In this technical solution, the buffer base is disposed, so that when in use, a gas valve
can be easily fixedly mounted to a position of use by mounting fastening bolts in through
holes, and a rubber cushion layer and a buffer spring in a buffer block cooperate to perform
functions of shock absorption and buffering at the same time when in use, thereby increasing
a service life of the gas value. A connection mechanism is disposed, so that when in use, a
threaded layer inside a pipe sleeve is threadedly connected to a gas pipeline, thereby making
pipeline interconnection more convenient. A threaded connection portion can be better
protected by disposing a protection ring sleeve, which prevents the connection portion from
leaking gas as a result of damage through long-term use. while safety hazards caused by gas
leakage can be prevented during connection of the valve by disposing a sealing cushion ring.
A safety mechanism is disposed, so that when in use, when a temperature at the outer side of
the gas valve is excessively high, a temperature sensor senses a signal at this time, a digital
signal processor (DSP) controller first controls the buzzer to send an alarm, then the signal is
transmitted by a signal transmitter to remotely notify an alarm. When the gas leaks, a gas
sensor senses a signal, and the DSP controller controls operation of a electromagnetic valve.
In response, the electromagnetic valve is closed to cut off gas supply, and then an alarm
device produces an alarm. A gas pressure gauge is disposed to observe an internal gas
pressure at all times, thereby reducing a possibility of fire. An adjusting bolt can be rotated as
needed by disposing a pressure regulating mechanism. The adjusting bolt rotates inside a
connection port to enable a sealing pressing block to press against a pressure spring to further
increase the tension of the pressure spring, thereby increasing a pressure and performing a
function of adjusting the pressure. Moreover, the inside of the connection port can be better
sealed by disposing a sealing ring to further prevent gas leakage. When a gas valve body runs,
the gas enters into a pressure reducing cavity through a nozzle hole to enable a central
diaphragm shaft to lift an equalizer lever. Since the pressure spring applies a certain pressure,
a diaphragm assembly and the equalizer lever mutually expand to enable the equalizer lever
to close the nozzle hole, and it is in a closed position at this time. After a user opens the gas
stove, the pressure spring interacts with the diaphragm assembly and the equalizer lever at
this time to enable the gas to reach a required pressure. The equalizer lever opens the nozzle
hole. By means of such repeated adjusting processes, the internal pressure of the pressure
reducing cavity is enabled to maintain a constant state, so that the pressure at a gas outlet end
is stable regardless of whether an intake pressure is excessively high or excessively low,
thereby performing the function of reducing and stabilizing the pressure.
(2) The buffer base is disposed, so that when in use, the gas valve can be easily fixedly
mounted to the position of use by mounting the fastening bolts in the through holes.
Meanwhile, when an external object touches the gas valve, the rubber cushion layer and the
buffer spring in the buffer block cooperate with each other to contract and rebound at this
time, thereby reducing the vibration when encountering a collision and during the use, further
effectively enhancing anti-vibration and anti-impact capabilities of the gas value and increasing the service life and safety of the gas valve.
(3) The connection mechanism is disposed, so that after the mounting is finished, the
threaded layer inside the pipe sleeve is threadedly connected to an external gas pipeline,
thereby making the pipeline interconnection more convenient. Moreover, the threaded
connection portion can be better protected by disposing the protection ring sleeve to prevent
the pipeline at the connection portion from leaking gas as a result of damage through
long-term use of the connection portion, and safety hazards caused by gas leakage are
prevented during the connection process by disposing the sealing cushion ring.
(4) The safety mechanism is disposed, so that when in use, when a temperature at the
outer side of the gas valve is excessively high, the temperature sensor senses a signal. The
DSP controller first controls the buzzer to send an alarm. Then, the signal is transmitted by
the signal transmitter to remotely notify the alarm. When the gas leaks, the gas sensor senses
a signal. The DSP controller controls the electromagnetic valve to operate at this time. The
electromagnetic valve is closed to cut off gas supply, and then the alarm device gives an
alarm. The gas pressure gauge is disposed to observe an internal gas pressure at all times,
thereby reducing a possibility of fire. In this way, the safety of the gas valve is further
effectively enhanced when in use, and the possibility of fire and other safety hazards is
minimized.
(5) The pressure regulating mechanism is disposed, so that the adjusting bolt can be
rotated as needed, the adjusting bolt rotates inside the connection port at this time to enable
the sealing pressing block to press against the pressure spring to further increase the tension
of the pressure spring, thereby increasing a pressure and performing a function of adjusting
the pressure. Moreover, the inside of the connection port can be better sealed by disposing the sealing ring to further prevent the leakage of the gas and enhance the adjusting convenience of the gas valve.
(6) The zinc oxide layer is disposed, so that the surface of the upper cover has optimal
capabilities of fire and corrosion resistance. The stainless steel layer and the tungsten steel
layer cooperate with each other to further enhance an inspection degree of the upper cover to
ensure the safety of the device when in use. Additionally, the pressure reducing valve body
made of the aluminum alloy material is disposed to enhance the capability of temperature
resistance of the gas valve body while reducing the cost of the product, thereby making the
gas valve more practical.

Embodiment:
Referring to FIGS. 1-8, a novel low-pressure gas pressure reducing valve includes the
pressure reducing valve body 1. The top portion of the pressure reducing valve body 1 is fixedly connected to the upper cover 2. The gas inlet end 3 is formed on the right side of the pressure reducing valve body 1, and the nozzle hole 4 is disposed in the gas inlet end 3. The gas outlet end 5 is formed on the left side of the pressure reducing valve body 1. The pressure reducing cavity 6 is disposed inside the pressure reducing valve body 1, and the central diaphragm shaft 7 is disposed at the middle of the inner bottom portion of the cavity body of the pressure reducing cavity 6. The upper end of the inner right side of the cavity body of the pressure reducing cavity 6 is hinged to the equalizer lever 8 through a pin shaft, and the left end portion of the equalizer lever 8 is movably connected to the surface of the central diaphragm shaft 7. The diaphragm assembly 9 is disposed at the top end of the pressure reducing valve body 1. The upper end of the central diaphragm shaft 7 penetrates the diaphragm assembly 9, and the central shaft spring 10 is fixedly mounted at the upper end of the central diaphragm shaft 7. The central shaft fastening member 11 is fixedly mounted at the upper end of the central shaft spring 9. The pressure spring 12 is fixedly mounted on the outer side of the central shaft spring 10 at the middle of the top portion of the diaphragm assembly 9. The top portion of the central shaft spring 10 is fixedly connected to the inside of the upper end of the pressure spring 12 through the central shaft fastening member 11. The pressure regulating mechanism 13 is disposed at the middle of the top portion of the upper cover 2 on the upper end of the central shaft spring 10. The left side of the gas inlet end 3 is fixedly connected to the safety mechanism 14. Each of the outer side of the safety mechanism
14 and the outer side of the gas outlet end 5 is fixedly connected to the connection
mechanism 15. The bottom portion of the pressure reducing valve body 1 is fixedly mounted
with the buffer base 16.
In this technical solution, the buffer base 16 is disposed, so that when in use, the gas
valve can be easily fixedly mounted to a position of use by mounting fastening bolts in through holes 1654, and the rubber cushion layer 1652 and the buffer spring 164 in the buffer block 1651 cooperate to perform functions of shock absorption and buffering at the same time when in use, thereby increasing a service life of the gas value. The connection mechanism 15 is disposed, so that when in use, the threaded layer 152 inside the pipe sleeve
151 is threadedly connected to a gas pipeline, thereby making pipeline interconnection more
convenient. The threaded connection portion can be better protected by disposing the
protection ring sleeve 153, which prevents the connection portion from leaking gas as a result
of damage through long-term use, while safety hazards caused by gas leakage can be
prevented during connection of the valve by disposing the sealing cushion ring 154. The
safety mechanism 14 is disposed, so that when in use, when a temperature at the outer side of
the gas valve is excessively high, the temperature sensor 1441 senses a signal. The DSP
controller 1431 first controls the buzzer 1433 to send an alarm, then the signal is transmitted
by the signal transmitter 1432 to remotely notify the alarm. When the gas leaks, the gas
sensor 1442 senses a signal, the DSP controller 1431 controls operation of the
electromagnetic valve 141. In response, the electromagnetic valve 141 is closed to cut off gas
supply, and then the alarm device 143 gives an alarm. The gas pressure gauge 142 is disposed
to observe an internal gas pressure at all times, thereby reducing a possibility of fire. The
adjusting bolt 132 can be rotated as needed by disposing the pressure regulating mechanism
13. The adjusting bolt 132 rotates inside the connection port 131 at this time to enable the
sealing pressing block 133 to press against the pressure spring 12 to further increase the
tension of the pressure spring 12, thereby increasing a pressure and performing a function of
adjusting the pressure. Moreover, the inside of the connection port 131 can be better sealed
by disposing the sealing ring 134 to further prevent the leakage of the gas. When a gas valve
body runs, the gas enters into the pressure reducing cavity 6 through the nozzle hole 4 to enable the central diaphragm shaft 7 to lift the equalizer lever 8, and since the pressure spring
12 applies a certain pressure, the diaphragm assembly 9 and the equalizer lever 8 mutually
expand to enable the equalizer lever 8 to close the nozzle hole 4, and it is in a closed position
at this time. After a user opens the gas stove, the pressure spring 12 interacts with the
diaphragm assembly 9 and the equalizer lever 8 at this time to enable the gas to reach a
required pressure. The equalizer lever 8 opens the nozzle hole 4. By means of such repeated
adjusting processes, the internal pressure of the pressure reducing cavity 6 is enabled to
maintain a constant state, so that the pressure at the gas outlet end 5 is stable regardless of
whether the intake pressure is excessively high or excessively low, thereby performing the
function of reducing and stabilizing the pressure.
Referring to FIGS. 1 and 3, the buffer base 16 includes the fixed block 161, and the
square groove 162 is provided at the central portion of the fixed block 161. The concave
block 163 is fixedly mounted inside the square groove 162. The base material of the concave
block 163 is made of the rubber material. Buffer springs 164 are fixedly mounted on the inner
side of the bottom portion of the concave block 163 at equal intervals. The mounting base
165 is fixedly mounted at bottom portions of the buffer springs 164. The mounting base 165
includes the buffer block 1651, and the top portion of the buffer block 1651 is fixedly
mounted to the bottom portions of the buffer springs 164. The rubber cushion layer 1652 is

bottom portion of the buffer block 1651, and both sides of the transverse plate 1653 are
provided with the through hole 1654. The buffer base 16 is disposed, so that when in use, the
gas valve can be easily fixedly mounted to the position of use by mounting the fastening bolts
in the through holes 1654. Meanwhile, when an external object touches the gas valve, the
rubber cushion layer 1652 and the buffer spring 164 in the buffer block 1651 cooperate with each other to contract and rebound at this time, thereby reducing vibration when encountering a collision and during use, further effectively enhancing anti-vibration and anti-impact capabilities of the gas value and increasing the service life and safety of the gas valve.
Referring to FIG. 5, the connection mechanism 15 includes the pipe sleeve 151. The
pipe sleeve 151 is fixedly mounted on the outer side of the safety mechanism 14 and the outer

The adjusting bolt 132 is threadedly connected into the connection port 131, and the sealing pressing block 133 is fixedly mounted at the bottom portion of the adjusting bolt 132. The bottom portion of the sealing pressing block 133 is fitted and connected to the pressure spring 12, and the sealing ring 134 is disposed at the lower end of the connection port 131. The pressure regulating mechanism 13 is disposed, so that the adjusting bolt 132 can be rotated as needed. The adjusting bolt 132 rotates inside the connection port 131 at this time to enable the sealing pressing block 133 to press against the pressure spring 12 to further increase the tension of the pressure spring 12, thereby increasing a pressure and performing a function of adjusting the pressure. Moreover, the inside of the connection port 131 can be better sealed by disposing the sealing ring 134 to further prevent the leakage of the gas and enhance the adjusting convenience of the gas valve.
Referring to FIGS. 1 and 6, the outer side of the upper cover 2 is provided with the zinc
oxide layer 17, and the inner side of the upper cover 2 is fixedly connected to the stainless
steel layer 18 . The tungsten steel layer 19 is disposed inside the stainless steel layer 18. The
interior of the pressure reducing valve body 1 is manufactured using the aluminum alloy
material, and the left bottom of the equalizer lever 8 is fixedly connected to the sealing
cushion block 20. The upper cover 2 covers the pressure reducing valve body 1 by riveting.
The zinc oxide layer 17 is disposed, so that the surface of the upper cover 2 has optimal
capabilities of fire and corrosion resistance. The stainless steel layer 18 and the tungsten steel
layer 19 cooperate with each other to further enhance an inspection degree of the upper cover
2 to ensure the safety of the device when in use. Additionally, the pressure reducing valve
body 1 made of the aluminum alloy material is disposed to enhance the capability of
temperature resistance of the gas valve body while reducing the cost of the product, thereby
making the gas valve more practical. Moreover, the sealing cushion block 20 is disposed to
enable the bottom portion of the right end of the equalizer lever 8 to better seal the nozzle hole 4, thereby further enhancing the seal of the gas valve.
Referring to FIGS. 1-8, when in use, a gas valve can be first fixedly mounted to a
position of use by mounting fastening bolts in through holes 1654, and then the threaded
layer 152 inside the pipe sleeve 151 is threadedly connected to a gas pipeline, thereby making
pipeline interconnection more convenient. The threaded connection portion can be better
protected by disposing the protection ring sleeve 153, which prevents the connection portion
from leaking gas as a result of damage through long-term use, while safety hazards caused by
gas leakage can be prevented during connection of the valve by the sealing cushion ring 154.
During the use process, when an external object touches the gas valve, the rubber cushion
layer 1652 and the buffer spring 164 in the buffer block 1651 cooperate with each other to
contract and rebound at this time, thereby reducing the vibration when encountering a
collision and during the use, further effectively enhancing anti-vibration and anti-impact
capabilities of the gas valve and increasing the service life and safety of the gas valve. When
a temperature at the outer side of the gas valve is excessively high, the temperature sensor
1441 senses a signal. The DSP controller 1431 first controls the buzzer 1433 to send an alarm,
then the signal is transmitted by the signal transmitter 1432 to remotely notify the alarm to
enable workers to timely perform emergency repairs. When the gas leaks, the gas sensor 1442
senses a gas signal, the DSP controller 1431 controls operation of the electromagnetic valve
141. In response, the electromagnetic valve 141 is closed to cut off gas supply, and then the
DSP controller 1431 perform an alarm through the alarm device 143. The gas pressure gauge
142 is disposed to observe an internal gas pressure at all times, thereby reducing a possibility
of fire. When the gas pressure needs to be adjusted, the adjusting bolt 132 can be rotated as
needed. The adjusting bolt 132 rotates inside the connection port 131 at this time to enable
the sealing pressing block 133 to press against the pressure spring 12 to further increase the tension of the pressure spring 12, thereby increasing a pressure and performing a function of adjusting the pressure. Moreover, the inside of the connection port 131 can be better sealed by the sealing ring 134 to further prevent the leakage of the gas. When a gas valve body runs, the gas enters into the pressure reducing cavity 6 through the nozzle hole 4 to enable the central diaphragm shaft 7 to lift the equalizer lever 8. Since the pressure spring 12 applies a certain pressure, the diaphragm assembly 9 and the equalizer lever 8 mutually expand to enable the equalizer lever 8 to close the nozzle hole 4, and it is in a closed position at this time. After a user opens the gas stove, the pressure spring 12 interacts with the diaphragm assembly 9 and the equalizer lever 8 at this time to enable the gas to reach a required pressure.
The equalizer lever 8 opens the nozzle hole 4. By means of such repeated adjusting processes,
the internal pressure of the pressure reducing cavity 6 is enabled to maintain a constant state,
so that the pressure at the gas outlet end 5 is stable regardless of whether the intake pressure
is excessively high or excessively low, thereby performing the function of reducing and
stabilizing the pressure.
The above is the preferred embodiments of the present invention; but the scope of
protection of the present invention is not limited hereto. Any equivalent replacement or
change made by those skilled in the art within the technical scope disclosed by the present
invention according to the technical solution and improved concept of the present invention
