Abstract
The utility model relates to a large-flow and high-pressure air pressure reducer which comprises a pressure reducer body, a high-pressure pressure reduction device, an air inlet pressure gauge, an air outlet pressure gauge and a handle, wherein the high-pressure pressure reduction device comprises a valve body, a valve cover, a valve core and a valve seat, wherein a pressure reduction valve consists of spring pressing plates, a spring and a top rod; the spring is arranged between the upper spring pressing plate and the lower spring pressing plate; and the top rod is arranged on the lower surface of the lower spring pressing plate. The large-flow and high-pressure air pressure reducer is characterized in that the spring is sleeved at the top end of the valve core; a plunger piston is arranged between the valve core and the upper spring pressing plate; and the air inlet pressure gauge is connected with a filter element. As a reset spring is additionally arranged at the part of the valve body, the pressure reduction efficiency of the pressure reducer can be improved, so that the air pressure inside the valve body is quickly balanced.
Description
Technical field
The utility model relates to a kind of big-flow high-pressure air pressure reducer.
Background technique
Air pressure reducer is that the gas in the gas cylinder is reduced pressure and carries out the device of Flow-rate adjustment.The kind of gas pressure reducer is many, and its utilization purpose is different, and is also different to the requirement of decompressor.If get into the instantaneous increase of pressure of gas, can cause delivery pressure to increase, at this moment, if spool can not in time play regulating action, the efficient of decompressor will reduce greatly.
Summary of the invention
The utility model is in order to improve the working efficiency of air pressure reducer; A kind of big-flow high-pressure air pressure reducer is provided; Comprise the decompressor body, and high pressure relief device, boost gauge and give vent to anger pressure gauge and handle formation, its high pressure relief device is made up of valve body, valve gap, spool and valve seat; Reduction valve is made up of spring bearer plate, spring and push rod; Spring is arranged between upper and lower two spring bearer plates, is provided with push rod below the lower spring pressing plate, and it is characterized in that: the top at spool is arranged with spring; Be provided with plunger between spool and the upper spring pressing plate; Boost gauge is connected with filter core.
The beneficial effect of the utility model is: critical piece adopts high-quality corrosion-resistant stainless steel manufacture of materials, has corrosion-resistant, high pressure resistant advantage; Adopt the plunger type pressure reduction structure, advantage such as have that flow is big, pressure stability, long service life, maintenance cost are low; Be designed with the installation screw thread on the valve gap and make that installation is very convenient; Suction port is provided with filter core on the valve body, with the impurity in the filtering gas, improves working life; Boost gauge is installed on the valve body and gives vent to anger pressure gauge, can conveniently observe preceding pressure of decompression and decompression back pressure.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of big-flow high-pressure air pressure reducer; Comprise the decompressor body, and high-pressure filteration method, low pressure filter tap, boost gauge and give vent to anger pressure gauge and handle formation, its high-pressure filteration control valve unit is made up of valve body, valve gap, spool and valve seat; Reduction valve is made up of spring bearer plate, spring and push rod; Spring is arranged between upper and lower two spring bearer plates 6,8, is provided with push rod 9 below the lower spring pressing plate; The outside of spring is fixing through gland nut 7, and it is characterized in that: the top at spool is arranged with spring; Be provided with plunger between spool and the upper spring pressing plate 6; Boost gauge is connected with filter core.
Before air inlet; Spool 13 is in open mode under the elastic force effect of spring 11, this moment, gas got into from the aperture of valve seat 3 after filter core 2 filters in the chamber of valve seat 3 and plunger 12 formation, and the gas pressure in the chamber increases from low to high gradually; When it affacts on the plunger 12 pressure greater than the elastic force of spring 11; Plunger 12 moves downward, and along with the pressure in the chamber further increases, spool 13 moves downward under spring 15 elastic force effects; Increase to spool 13 up to pressure and closely contact, second form sealing with valve seat 3.At this moment, gas can not get into chamber from suction port, and the pressure in the chamber no longer raises, pressure level-off, and this pressure can be through pressure gauge 14 observations of giving vent to anger.When the gas in the chamber when flow out the air outlet; Its internal pressure constantly reduces; When pressure is reduced to it when acting on pressure on the plunger 12 less than the elastic force of spring 11, plunger 12 moves upward under the elastic force effect, and plunger 12 promotes spools 13 and moves upward; Spool 13 disengages with valve seat 3, second can not form sealing.At this moment, gas passes through from the aperture of valve seat 3, to get in the chamber of valve seat 3 and plunger 12 formation after filter core 2 filters, and the gas pressure in the chamber is increase gradually from low to high.Thus, decompressor completion air inlet-reduce pressure-close-air inlet-decompression process.
Going out atmospheric pressure can adjust according to actual needs, through the elastic force of turn handle 10 Regulation springs 11, thereby regulates the decompressor delivery pressure, and the handle with sleeve delivery pressure increases in the clockwise direction, and outwards the rotatable handle delivery pressure reduces counterclockwise.
