The utility model has the advantages that the fluctuation range of setting pressure P2 is decreased, and the sensitivity of the regulator is enhanced; the utility model has the characteristics of simple pressure setting, high pressure regulating precision and fast reaction speed.
Description
The utility model relates to fluid pressure actuator, particularly a kind of direct acting type gas pressure regulator that is used for gas-fired equipment pipeline pressure automatic regulating system.
At present, in the pipeline pressure automatic regulating system, automatic pressure regulator mainly is divided into " indirect acting type pressure regulator " and " direct acting type pressure regulator " two big classes, the indirect acting type pressure regulator is to preestablish pressure with pilot valve, by pressure medium (P2) behind the control valve control valve, what the direct acting type pressure regulator adopted is directly to set the operating pressure of control valve to regulate P2 pressure again.The direct acting type pressure regulator is compared with the indirect acting type pressure regulator, have reaction speed fast, be active in one's movements, characteristics that time lag is short.The direct acting type pressure regulator is divided into two types again, the lever amplification and pressure regulator no lever amplification are promptly arranged, for the direct acting type pressure regulator that the lever amplification is arranged, the force position at the lever two ends of prior art is with the action of pin transfer reaction, owing to certainly exist bigger gap between pin and lever, this gap is actually the error of the power that presets that has increased setting spring, also just equals to have increased the fluctuation range of setting pressure P2, and this is disadvantageous to pressure regulating performance.
The purpose of this utility model is for overcoming the defective that prior art exists, and by to the reducing of lever termination drive gap, makes full use of the lever amplification, makes the action of pressure regulator in adjustment process sensitiveer, and regulating error is littler, satisfies highly sensitive requirement.
The purpose of this utility model is achieved through the following technical solutions:
High sensitivity direct acting type gas pressure regulator, comprise by the film chamber, diaphragm, pallet, lever, the executing agency that the pressure setting spring is formed and by valve body, flap, the control valve that pressure signal pipe is formed, executing agency is arranged on the top of control valve, it is characterized in that: the lever two ends of executing agency link with pallet termination and valve rod termination respectively, be provided with cavity in pallet termination and the valve rod termination, floating part is set in the cavity, wherein in the cavity of last floating part, be provided with the floating part spring, the two ends of lever insert respectively pallet termination and valve rod termination on, between the following floating part.
According to the high sensitivity direct acting type gas pressure regulator that the utility model proposes, utilize the combination of floating part and floating part spring, formed the elimination clearance mechanism, simultaneously guaranteed not produce interference drag again, the compression height fluctuation range of pressure regulator pressure setting spring in adjustment process reduced, also just reduce the error of compression spring setting power, reduced the fluctuation range of setting pressure P2, the sensitivity that has improved adjuster.
The utility model pressure regulating performance is good, have pressure and set simple, pressure regulation precision height, the fast characteristics of reaction speed, be suitable for various direct combustion equipment and small area and building, building, be used for the automatic pressure control of multiple gases such as natural gas, artificial coal gas, liquefied petroleum gas, air.
Fig. 1 is the structural representation of the utility model embodiment.
The utility model will be further described according to accompanying drawing embodiment below:
As shown in the figure, high sensitivity direct acting type gas pressure regulator is mainly set the executing agency that regulating part 7 forms by film chamber 12, diaphragm 6, pallet 5, lever 3, pressure setting spring 8, pressure and the control valve of being made up of valve body 13, flap 9, pressure signal pipe 11 constitutes.Pressure is set the epicoele that regulating part 7 and pressure setting spring 8 are located at the film chamber, pressure setting spring 8 with contact above the pallet 5, film chamber cavity of resorption is a leverage, is provided with pressure signal pipe 11 between the downstream of film chamber cavity of resorption and valve body 13 and is communicated with.Executing agency connects the top that is arranged on control valve valve body 13 by bolt, utilizes in the pipeline and presses, and pressure P 2 behind the automatic regulating valve.
Lever 3 two ends of executing agency link with the valve rod termination 15 of pallet termination 14 that is located at pallet 5 centers and valve rod 4 respectively, be equipped with cavity in pallet termination 14 and the valve rod termination 15, floating part 1 is set in the cavity, wherein be provided with floating part spring 2 in the cavity of last floating part, insert respectively between the upper and lower floating part of pallet termination and valve rod termination at the two ends of lever 3.
During use, when valve body 13 upstream pressures are that the gas of P1 enters control valve, to the control valve downstream, pressure medium becomes P2 by valve port 10, introduces film chamber 12 cavity of resorptions by downstream pressure signal pipe 11, pallet 5 and diaphragm 6 produce power upwards, power with pressure setting spring 8 balances each other simultaneously, if P2 pressure is higher than setting value, then promotes diaphragm 6 and pallet 5 risings, lever 3 drove valve rods 4, flap and was about to valve port for 9 times and turns down this moment, made under the P2 and rolled back setup pressure value.Otherwise if P2 pressure is lower than setup pressure value, pressure setting spring 8 promotes diaphragm 6 and pallet 5 descends, and lever 3 drives valve rod 4, upwards operation of flap 9, and valve port is opened greatly, makes P2 pressure rise to setting value, thereby reaches the purpose of automatic stabilisation downstream pressure P2.
