Abstract
The utility model belongs to the technical field of fuel gas transmission and distribution equipment and discloses a double-piston balanced type voltage regulator. The voltage regulator has the main technical characteristics that the voltage regulator comprises a valve body provided with an air inlet, an air outlet and a valve seat, wherein the valve body is connected with a membrane casing; a membrane and a pallet are arranged in the membrane casing; a valve rod connected with the pallet is arranged at the lower part of the membrane; a main piston matched with the valve seat is arranged at the bottom end of the valve rod; the main piston is provided with a through hole; an auxiliary piston guide sleeve connected with the pallet is arranged at the upper part of the membrane, and is connected with an auxiliary piston with one end fixed on the membrane casing; and a through chamber communicated with the auxiliary piston guide sleeve is arranged in the valve rod. In the double-piston balanced type voltage regulator provided by the utility model, the valve seat keeps normal opening all the time regardless of the pressure variation of the fuel gas at the air inlet, so that the pressure balance effect of the fuel gas at the air inlet is very good, and the influence on the voltage regulator caused by the pressure variation of the fuel gas at the air inlet is eliminated.
Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of double-piston balanced type 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 it be stabilized in a certain pressure range, satisfies the force value of customer requirements, satisfies usage requirement.The gas pressure regulator, governor of current use, its structure comprises the housing that has suction port, air outlet and valve seat, be provided with diaphragm in the housing, diaphragm top is provided with pallet, pressure adjusting spring, adjustable lever and adjusting nut, the diaphragm bottom is provided with the valve rod that is connected with pallet, and the valve rod bottom is provided with the valve alive that is complementary with valve seat.Pressure governor is when proper functioning, and air outlet pressure acts on the power of diaphragm bottom surface and power that pressure adjusting spring acts on the diaphragm end face reaches balance, and valve rod is static, and valve port is in normal open mode.When air outlet pressure raises, when the power that air outlet pressure acts on the diaphragm bottom surface acts on the power of diaphragm end face greater than pressure adjusting spring, diaphragm drives pallet and moves up, pallet moves up and drives valve rod and move up, valve rod drives the valve of living and moves up, the valve port of valve alive and valve base chamber reduces, and makes air outlet pressure reduce to recover normal value, thereby keeps normal air feed.When air outlet pressure reduces, when the power that air outlet pressure acts on the diaphragm bottom surface acts on the power of diaphragm end face less than pressure adjusting spring, diaphragm drives pallet and moves down, pallet moves down the drive valve rod and moves down, valve rod drives the valve of living and moves down, the valve port of valve alive and valve base chamber increases, and air outlet pressure is increased recover normal value, thereby keep normal air feed.The gas pressure regulator, governor of this structure, suction port pressure acts directly on the diaphragm, adjusts gas port pressure by compression, stretching, extension pressure adjusting spring, and its counterbalance effect is not fine.
The model utility content
Problem to be solved in the utility model just provides a kind of double-piston balanced type pressure governor of good balance effect.
For addressing the above problem, the technical solution adopted in the utility model is: comprise having suction port, the valve body of air outlet and valve seat, described valve body is connected with the diaphragm housing, be provided with diaphragm and pallet in the diaphragm housing, the diaphragm bottom is provided with the valve rod that is connected with pallet, the valve rod bottom is provided with the main piston that is complementary with valve seat, main piston is provided with through hole, diaphragm top is provided with the sub-piston guide sleeve that is connected with pallet, the sub-piston guide sleeve is connected with the sub-piston that an end is fixed on the diaphragm housing, and valve rod inside is provided with the logical thorax that is connected with the sub-piston guide sleeve.
A kind of double-piston balanced type pressure governor provided by the utility model, main piston acts on the power of diaphragm bottom and the equilibrium of forces that sub-piston acts on diaphragm top at ordinary times, and valve seat is in normal open mode.When combustion gas enters valve body by suction port, combustion gas not only arrives the air outlet by the main piston bottom, and also the through hole by main piston enters into main piston top, reaches the purpose of balance main piston upper and lower end gas pressure.Simultaneously, combustion gas also arrives the bottom of sub-piston in the sub-piston guide sleeve by the inner logical thorax of valve rod, makes main piston act on the power of diaphragm bottom and power that sub-piston acts on diaphragm top still keeps balance, and valve seat keeps normal open mode.Like this, no matter how the suction port gaseous-pressure changes, valve seat keeps normal open mode always, and balance gas inlet effect is very good, has eliminated the influence of suction port gaseous-pressure variation to pressure governor.
Description of drawings
Fig. 1 is the structural representation of a kind of double-piston balanced type of the utility model pressure governor.
Embodiment
Be described in further details below in conjunction with the structure and the working principle of accompanying drawing a kind of double-piston balanced type of the utility model pressure governor.
As shown in Figure 1, a kind of double-piston balanced type of the utility model pressure governor comprises valve body 1, valve body 1 has suction port 2, air outlet 3 and valve seat 4, valve body 1 is connected with diaphragm housing 5, be provided with diaphragm 6 and pallet 7 in the diaphragm housing 5, diaphragm 6 bottoms are provided with the valve rod 8 that is connected with pallet 7, valve rod 8 bottoms are provided with the main piston 9 that is complementary with valve seat 4, main piston 9 is provided with through hole 10, diaphragm 6 tops are provided with the sub-piston guide sleeve 11 that is connected with pallet 7, sub-piston guide sleeve 11 is connected with the sub-piston 12 that an end is fixed on the diaphragm housing 5, and valve rod 8 inside are provided with the logical thorax 13 that is connected with sub-piston guide sleeve 11.
A kind of double-piston balanced type pressure governor provided by the utility model, main piston 9 acts on the power of diaphragm 6 bottoms and the equilibrium of forces that sub-piston 12 acts on diaphragm 6 tops at ordinary times, and valve seat 4 is in normal open mode.When combustion gas enters valve body 1 by suction port 2, combustion gas not only arrives air outlet 3 by main piston 9 bottoms, and also the through hole 10 by main piston 9 enters into main piston 9 tops, reaches the purpose of balance main piston 9 upper and lower end gas pressures.Simultaneously, combustion gas also arrives the bottom of sub-piston 12 in the sub-piston guide sleeve 11 by valve rod 8 inner logical thoraxes 13, make main piston 9 act on the power of diaphragm 6 bottoms and power that sub-piston 12 acts on diaphragm 6 tops still keeps balance, valve seat 4 keeps normal open mode.Like this, no matter how the suction port gaseous-pressure changes, valve seat 4 keeps normal open mode always, and balance gas inlet effect is very good, has eliminated the influence of suction port gaseous-pressure variation to pressure governor.
