The main technical characteristics are that a valve body is comprised, wherein the valve body is provided with a gas inlet, a gas outlet, a valve port, a valve rod, and a pressure regulating cavity; a diaphragm is arranged in the pressure regulating cavity; a pressure regulating spring is arranged above the diaphragm in the pressure regulating cavity; a live valve matched with the valve port is arranged at the top end of the valve rod; the gas outlet is communicated with the pressure regulating cavity via a signal pipe; a connecting shaft connected with a transmission rod is arranged under the diaphragm; and the transmission rod and the tail end of the valve rod realize transmission through a gear. By adopting the gear to drive the valve rod, the gas pressure regulator provided by the utility model has stable and continuous transmission, low group blocking possibility, and high pressure stabilizing precision.
Description
Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of gas pressure regulator, 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, and 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 acted on the power of diaphragm end face greater than pressure adjusting spring, diaphragm drove pallet and moves up, and 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 acted on the power of diaphragm end face less than pressure adjusting spring, diaphragm drove pallet and moves down, and pallet moves down and drives valve rod and move 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, transmission are not very steady, are prone to card group phenomenon, and the precision of voltage regulation is lower.
The model utility content
It is continuous that the utility model technical problem to be solved just provides a kind of stable drive, is not prone to card group phenomenon, the gas pressure regulator, governor that the precision of voltage regulation is high.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: comprise valve body, valve body is provided with suction port, air outlet, valve port, valve rod and built-in chaffy pressure regulating cavity, and the top of pressure regulating cavity interior diaphragm is provided with pressure adjusting spring; Valve stem tip has the valve alive that is complementary with valve port; The air outlet is connected with pressure regulating cavity through signal tube, and the below of said diaphragm is provided with the coupling shaft that is connected with drive link, and the tail end of drive link and valve rod is through gear transmission.
During a kind of gas pressure regulator, governor proper functioning that the utility model provided, the power that pressure adjusting spring and air outlet pressure act on the diaphragm reaches balance, and valve rod is static, and valve port is in normal open mode.When the rising of air outlet pressure, air outlet pressure is delivered to pressure regulating cavity through signal tube, and the power that air outlet pressure acts on the diaphragm strengthens; The diaphragm compression pressure adjusting spring that moves up, coupling shaft drives drive link, and drive link drives valve rod through gear transmission and lives valve to moving near the valve port place; Valve and the valve port spacing of living reduces; Reduce gas throughput, make air outlet pressure reduce to recover normal value, thereby keep normal air feed.When the reduction of air outlet pressure, air outlet pressure is delivered to pressure regulating cavity through signal tube, and the power that air outlet pressure acts on the diaphragm reduces; Diaphragm moves down, and pressure adjusting spring stretches, and coupling shaft drives drive link; Drive link drives valve rod through gear transmission and lives valve to moving away from the valve port place, and live valve and valve port spacing strengthen, and increase gas throughput; Air outlet pressure is strengthened recover normal value, thereby keep normal air feed.A kind of gas pressure regulator, governor that the utility model provided adopts the gear transmission valve rod, and stable drive is continuous, is not prone to card group phenomenon, and the precision of voltage regulation is high.
Description of drawings
Fig. 1 is the structural representation of a kind of gas pressure regulator, governor of the utility model.
Embodiment
Explain further details below in conjunction with the structure and the working principle of accompanying drawing to a kind of gas pressure regulator, governor of the utility model.
As shown in Figure 1; A kind of gas pressure regulator, governor of the utility model comprises valve body 1, and valve body 1 is provided with suction port 2, air outlet 3, valve port 4, valve rod 5 and is built-in with the pressure regulating cavity 7 of diaphragm 6, and the top of pressure regulating cavity 7 interior diaphragms 6 is provided with pressure adjusting spring 8; Valve rod 5 tops have the valve alive 9 that is complementary with valve port 4; The below of diaphragm 6 is provided with the coupling shaft 11 that is connected with drive link 10, and drive link 10 passes through gear 12 transmissions with the tail end of valve rod 5, and air outlet 3 is connected with pressure regulating cavity 7 through signal tube 13.
During a kind of gas pressure regulator, governor proper functioning that the utility model provided, pressure adjusting spring 8 reaches balance with the power that air outlet 3 pressure act on the diaphragm 6, and valve rod 5 is static, and valve port 4 is in normal open mode.When the rising of air outlet 3 pressure, air outlet 3 pressure are delivered to pressure regulating cavity 7 through signal tube 13, and the power that air outlet 3 pressure act on the diaphragm 6 strengthens; Diaphragm 6 moves up and compresses pressure adjusting spring 8, and coupling shaft 11 drives drive links 10, and drive link 10 makes valve rod 5 drive the valve 9 of living to moving near valve port 4 places through gear 12 transmissions; The valve 9 of living reduces with valve port 4 spacings; Reduce gas throughput, make air outlet 3 pressure reduce to recover normal value, thereby keep normal air feed.When the reduction of air outlet 3 pressure, air outlet 3 pressure are delivered to pressure regulating cavity 7 through signal tube 13, and the power that air outlet 3 pressure act on the diaphragm 6 reduces; Diaphragm 6 moves down, and pressure adjusting spring 8 stretches, and coupling shaft 11 drives drive link 10; Drive link 10 drives valve rod 5 through gear 12 transmissions and lives valve 9 to moving away from valve port 4 places, and the valve 9 of living strengthens with valve port 4 spacings, increases gas throughput; Air outlet 3 pressure are strengthened recover normal value, thereby keep normal air feed.
