Abstract
The utility model belongs to the technical field of gas equipment, and discloses a high-pressure axial flow type gas pressure regulator. The high-pressure axial flow type gas pressure regulator is mainly technically characterized in that: the gas pressure regulator comprises a shell with a gas inlet and a gas outlet, wherein the inside of the shell is provided with a valve port pad, a diaphragm and a valve barrel connected with the diaphragm; the bottom of the valve barrel is close to the valve port pad; the shell is divided into an upper space and a lower space by the diaphragm; the inside of the upper space is provided with a pressure adjusting spring and communicated with the gas outlet through a signal feedback pipe; the lower space is connected with a pivot regulator through a signal pipe; and the shell is provided with a valve position indicator. The shell of the high-pressure axial flow type gas pressure regulator provided by the utility model is provided with the valve barrel inside, so a path is formed in the shell and the gas directly flows through the shell. Compared with the traditional pressure regulator with the same caliber, the high-pressure axial flow type gas pressure regulator has greater flow and is suitable for high-pressure mass flow gas.
Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of high-pressure shaft streaming gas pressure regulator, governor.
Background technique
In recent years, China's combustion gas cause obtained flourish, served as theme with the transfering natural gas from the west to the east main artery, and various places are set up urban gate station in succession, divided defeated station to wait to accelerate making full use of of eco-friendly power source.To be combustion gas enter the key equipment of urban pipe network from long-distance transport pipes to urban gate station, and combustion gas Men Zhanzhong is the center with the combustion gas regulator, and the nucleus equipment of combustion gas regulator is a gas pressure regulator, governor.The pressure governor that current China produces mostly based in, low pressure, on using scope, be very limited, be unsuitable for high pressure, big flow combustion gas.
The model utility content
Problem to be solved in the utility model just provides a kind of high-pressure shaft streaming gas pressure regulator, governor that is suitable for high pressure, big flow combustion gas.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the housing that has suction port, air outlet, be provided with valve port pad, diaphragm and the valve cylinder that is connected with diaphragm in the described housing, the valve cylinder bottom is mutually close with the valve port pad, diaphragm is separated into epicoele and cavity of resorption with housing, be provided with pressure adjusting spring in the epicoele and be connected with the air outlet by the signal feed back pipe, cavity of resorption is connected with pilot valve by the signal pipe.
Its additional technical feature is: described housing is provided with valve phase indicator.
High-pressure shaft streaming gas pressure regulator, governor provided by the utility model is provided with valve cylinder in the housing, make housing become latus rectum, and the gas direct current passes through, and compares with traditional pressure governor of equal bore, has bigger flow, is suitable for the high-pressure high-flow combustion gas.Pressure governor is when proper functioning, air outlet pressure enters epicoele through the signal feed back pipe, common downwards firmly with epicoele internal pressure-regulating spring, and the pressure of air outlet enters cavity of resorption upwards firmly through the pilot valve decompression by the signal pipe, power upwards and downward power reach balance, keep certain distance between valve cylinder bottom and valve port pad, valve port is in normal open mode.When air outlet pressure raises, the signal feed back pipe in time feeds back to epicoele with the outlet pressure signal, the power that the downward power of epicoele makes progress greater than cavity of resorption, diaphragm drives valve cylinder and moves down, distance reduces between valve cylinder bottom and valve port pad, valve port reduces, and makes air outlet pressure reduce to recover normal value, thereby reaches the purpose of decompression, voltage stabilizing.When air outlet pressure reduces, the signal feed back pipe in time feeds back to epicoele with the outlet pressure signal, the power that the downward power of epicoele makes progress less than cavity of resorption, diaphragm drives valve cylinder and moves up, distance strengthens between valve cylinder bottom and valve port pad, valve port strengthens, and air outlet pressure is increased recover normal value, thereby reach the purpose of supercharging, voltage stabilizing.And housing is provided with valve phase indicator, can observe the valve position height at any time.
Description of drawings
Accompanying drawing is the structural representation of the utility model high-pressure shaft streaming gas pressure regulator, governor.
Embodiment
Be described in further details below in conjunction with the structure and the working principle of the drawings and specific embodiments the utility model high-pressure shaft streaming gas pressure regulator, governor.
As shown in the figure, the utility model high-pressure shaft streaming gas pressure regulator, governor comprises housing 1, housing 1 has suction port 2, air outlet 3, be provided with valve port pad 4, diaphragm 5 and the valve cylinder 6 that is connected with diaphragm 5 in the housing 1, valve cylinder 6 bottoms are mutually close with valve port pad 4, and diaphragm 5 is separated into epicoele 7 and cavity of resorption 8 with housing 1, are provided with pressure adjusting spring 9 in the epicoele 7 and are connected with air outlet 3 by signal feed back pipe 10, cavity of resorption 8 is connected with pilot valve 12 by signal pipe 11, and housing 1 is provided with valve phase indicator 13.
Pressure governor is when proper functioning, air outlet 3 pressure enter epicoele 7 through signal feed back pipe 10, common firmly downward with epicoele 7 internal pressure-regulating springs 9, and the pressure of air outlet 3 enters cavity of resorption 8 upwards firmly through pilot valve 12 decompressions by signal pipe 11, power upwards and downward power reach balance, 4 on valve cylinder 6 bottoms and valve port pad keep certain distance, and valve port is in normal open mode.When air outlet 3 pressure raise, signal feed back pipe 10 in time feeds back to epicoele 7 with the outlet pressure signal, the power that epicoele 7 downward power make progress greater than cavity of resorption 8, diaphragm 5 drives valve cylinder 6 and moves down, 4 distances of valve cylinder 6 bottoms and valve port pad reduce, valve port reduces, and makes air outlet 3 pressure reduce to recover normal value, thereby reaches the purpose of decompression, voltage stabilizing.When air outlet 3 pressure reduce, signal feed back pipe 10 in time feeds back to epicoele 7 with the outlet pressure signal, the power that epicoele 7 downward power make progress less than cavity of resorption 8, diaphragm 5 drives valve cylinder 6 and moves up, 4 distances of valve cylinder 6 bottoms and valve port pad strengthen, valve port strengthens, and air outlet 3 pressure is increased recover normal value, thereby reach the purpose of supercharging, voltage stabilizing.And housing 1 is provided with valve phase indicator 13, can observe the valve position height at any time.
