Abstract
The utility model belongs to the technical field of gas delivery and distribution equipment, and discloses a balanced valve type pressure regulator. The balanced valve type pressure regulator is characterized in that the pressure regulator comprises an air inlet, an air outlet and a shut-off valve casing, wherein the casing is provided with a regulating cavity, a diaphragm arranged in the regulating cavity divides the regulating cavity into a lower cavity and an upper cavity, the lower cavity is communicated with the air outlet via a signal feedback pipe, a tray, a pressure regulating spring and a regulating nut are arranged in the upper cavity, the tray is connected with a regulating rod, the regulating rod is connected with a balancing rod via a connecting rod, and the bottom end of the balancing rod is provided with the balanced valve. The balanced valve type pressure regulator can regulate pressure at the outlet thereof automatically and meet the purposes of pressure regulating and stabilizing without replacing valve ports within any pressure range and under different pressure conditions.
Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of equilibrium valve formula pressure governor.
Background technique
Gas pressure regulator, governor is to be specially adapted in the gas transmission and distribution system being widely used in the gas transmission and distribution engineering as the combustion gas voltage adjusting device of pressure regulation, voltage stabilizing.Its effect is to regulate gas outlet pressure automatically, makes its step-down equipment that is stabilized in a certain pressure range, by the force value that reduces pressure, customer requirements is satisfied in voltage stabilizing, satisfies usage requirement.But current gas pressure regulator, governor, the size of changing valve port according to the different needs of inlet pressure reaches the effect of decompression, voltage stabilizing, uses to bother.
The model utility content
Problem to be solved in the utility model just provide a kind of simple in structure, be suitable for any inlet pressure ranges, under the different pressures situation, do not need to change the equilibrium valve formula pressure governor that valve port can reach pressure regulation, voltage stabilizing.
For addressing the above problem, the technical solution adopted in the utility model is: comprise having suction port, air outlet, cut-out valve housing, described housing is provided with regulates the chamber, be provided with diaphragm in the adjusting chamber and be divided into cavity of resorption and epicoele, cavity of resorption is connected with the air outlet by the signal feed back pipe, be provided with pallet, pressure adjusting spring and adjusting nut in the epicoele, pallet is connected with adjustable lever, and adjustable lever is connected by the balancing pole that connecting rod and bottom have equilibrium valve.
Its additional technical feature is: the top in described adjusting chamber is provided with blanking cover.
Equilibrium valve formula pressure governor provided by the utility model, housing are provided with regulates the chamber.Pressure governor is when proper functioning, and air outlet pressure enters the diaphragm cavity of resorption through the signal feed back pipe, and the power that makes progress in the diaphragm cavity of resorption and epicoele internal pressure-regulating spring are set downward power and reached balance, and adjustable lever, connecting rod, balancing pole are static, and valve port is in normal open mode.When air outlet pressure raises, the signal feed back pipe in time feeds back to the diaphragm cavity of resorption with the outlet pressure signal, when the power that the diaphragm cavity of resorption makes progress is set downward power greater than diaphragm epicoele internal pressure-regulating spring, diaphragm drives pallet and moves up, pallet moves up and drives adjustable lever and move up, and adjustable lever moves down by the balancing pole that connecting rod makes the bottom have equilibrium valve, and valve port reduces, make air outlet pressure reduce to recover normal value, thereby reach the purpose of decompression, voltage stabilizing.When air outlet pressure reduces, the signal feed back pipe in time feeds back to the diaphragm cavity of resorption with the outlet pressure signal, when the power that the diaphragm cavity of resorption makes progress is set downward power less than diaphragm epicoele internal pressure-regulating spring, diaphragm drives pallet and moves down, pallet moves down the drive adjustable lever and moves down, and adjustable lever moves up by the balancing pole that connecting rod makes the bottom have equilibrium valve, and valve port increases, air outlet pressure is increased recover normal value, thereby reach the purpose of pressurization, voltage stabilizing.This pressure governor can be regulated the size of its outlet pressure automatically, is suitable for any inlet pressure ranges, does not need to change the purpose that valve port can reach pressure regulation, voltage stabilizing under the different pressures situation.And the top of regulating the chamber is provided with blanking cover, can prevent that pressure adjusting spring and adjusting nut from coming off.
Description of drawings
Accompanying drawing is the structural representation of the utility model equilibrium valve formula pressure 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 equilibrium valve formula pressure governor.
As shown in the figure, the utility model equilibrium valve formula pressure governor comprises housing 1, housing 1 has suction port 2, air outlet 3, cut-off valve 4 and regulates chamber 5, be provided with diaphragm 6 in the adjusting chamber 5 and be divided into cavity of resorption 7 and epicoele 8, cavity of resorption 7 is connected with air outlet 3 by signal feed back pipe 9, be provided with pallet 10, pressure adjusting spring 11 and adjusting nut 12 in the epicoele 8, pallet 10 is connected with adjustable lever 13, adjustable lever 13 is connected by the balancing pole 16 that connecting rod 14 and bottom have equilibrium valve 15, and the top of regulating chamber 5 is provided with blanking cover 17.
The utility model equilibrium valve formula pressure governor is when proper functioning, air outlet 3 pressure enter cavity of resorption 7 through signal feed back pipe 9, the power that makes progress in the cavity of resorption 7 and epicoele 8 internal pressure-regulating springs 11 are set downward power and are reached balance, and adjustable lever 13, connecting rod 14, balancing pole 16 are static, and valve port is in normal open mode.When air outlet 3 pressure raise, signal feed back pipe 9 in time feeds back to cavity of resorption 7 with the outlet pressure signal, when the power that cavity of resorption 7 makes progress is set downward power greater than epicoele 8 internal pressure-regulating springs 11, diaphragm 6 drives pallet 10 and moves up, pallet 10 moves up and drives adjustable lever 13 and move up, and adjustable lever 13 moves down by the balancing pole 16 that connecting rod 14 makes the bottom have equilibrium valve 15, and valve port reduces, make air outlet 3 pressure reduce to recover normal value, thereby reach the purpose of decompression, voltage stabilizing.When air outlet 3 pressure reduce, signal feed back pipe 9 in time feeds back to cavity of resorption 7 with the outlet pressure signal, when the power that cavity of resorption 7 makes progress is set downward power less than epicoele 8 internal pressure-regulating springs 11, diaphragm 6 drives pallet 10 and moves down, pallet 10 moves down drive adjustable lever 13 and moves down, and adjustable lever 13 moves up by the balancing pole 16 that connecting rod 14 makes the bottom have equilibrium valve 15, and valve port increases, air outlet pressure is increased recover normal value, thereby reach the purpose of pressurization, voltage stabilizing.And the top of regulating chamber 5 is provided with blanking cover 17, can prevent that pressure adjusting spring 11 and adjusting nut 12 from coming off.
