Abstract
The utility model disclose a fuel gas pressure regulating device, which comprises a main valve mounted on a fuel gas pipeline and a director with a valve, wherein the director is connected between a gas inlet and a gas outlet of the main valve through a pipe, and controls the main valve through the pressure difference between the gas inlet and the gas outlet of the main valve; a filter and a heater are sequentially connected between the gas inlet of the main valve and the gas inlet of the director valve through pressure taking pipes; and the gas outlet of the director valve is connected with the main valve through a pipe. The fuel gas pressure regulating device is simple in principle and strong in practicability; by virtue of the filter and the heater added before the director valve, the fuel gas is filtered and heated, then input to the director valve, which effectively solves the ice plugging problem due to throttling phenomenon when the fuel gas flows through the director valve.
Description
Technical field
The utility model relates to a kind of apparatus relevant with combustion gas, relates in particular to a kind of Gas Pressure Regulating Equipment that installs upper heater and filter additional.
Background technique
At present, the combustion gas by pipeline supply is more or less with some moisture, in the winter of combustion gas course of conveying; for prevent because of temperature low; and the icing phenomenon that occurs easily, ducted gas can pass through first moisture filter (or processing) usually, carries out the defeated biography of pipeline again.Gas Pressure Regulating Equipment is to make the outlet combustion gas keep the equipment of authorized pressure by automatic change through the gas flow of main valve.When gas flow during through regulator and since ducted gas with moisture can't remove thoroughly, so gas mercury dropped that can cause because of pressure drop, thereby so that combustion gas in regulator, occurs icing and blocks up phenomenon.The gas pressure regulation is to control by the pilot valve on the regulator, at first, gas is inputted pilot valve from pressure pipe, because the caliber of pressure pipe is thinner, when gas passes through the pilot valve valve, Choking phenomenon can occur, thereby cause drop in temperature (every decline 1KG pressure, 0.4 ℃ of drop in temperature) so that gas pressure descends, if in the gas with moisture, the stifled phenomenon of ice will appear in the pilot valve valve of this moment, and then cause regulator not worked, and affect the downstream normal air feed of pipeline of upstream line.
Summary of the invention
The utility model provides a kind of Gas Pressure Regulating Equipment for solving existing issue, and its principle is simple, practical, can effectively solve the stifled problem of ice that combustion gas occurs when flowing through the pilot valve valve.
In order to address the above problem, the utility model is taked following technological scheme: a kind of Gas Pressure Regulating Equipment, comprise: be installed in main valve and the pilot valve that carries valve on the gas pipeline, described pilot valve is attempted by between the advancing of main valve/air outlet by pipeline, pilot valve by the contrast main valve advance/air outlet between the pressure difference of gas control the folding of main valve; The suction port of described main valve is connected with filter and heater between the suction port of pilot valve valve in turn by pressure pipe; The air outlet of described pilot valve valve is connected with main valve by pipeline.
The utility model principle is simple, practical, by before the pilot valve valve, adding fixed filter and heater, make combustion gas pass through first contaminant filter and heat tracing, input again the pilot valve valve, thereby effectively solve the stifled problem of ice that combustion gas occurs when flowing through the pilot valve valve.
Description of drawings
Fig. 1 is the principle sketch of existing regulator.
Fig. 2 is principle sketch of the present utility model.
Embodiment
Understanding for the ease of those skilled in the art is described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, be existing regulator, it includes: main valve 1 and pilot valve 2, the suction port of described main valve is to connecting by pressure pipe 3 between the suction port of pilot valve valve.When upstream line through regulator downstream during gas supply conduit, the gas of regulator suction port end flows into the pilot valve valve along pressure pipe, because the caliber of pressure pipe is thinner, when gas passes through the pilot valve valve, Choking phenomenon can appear, thereby so that descending, gas pressure causes drop in temperature, especially in the winter of cold, if in the gas with moisture, the stifled phenomenon of ice will appear in the valve of pilot valve, and then cause pressure governor not worked, affect the downstream normal air feed of pipeline of upstream line.
As shown in Figure 2, embodiment for regulator described in the utility model, a kind of Gas Pressure Regulating Equipment, comprise: be installed in main valve 1 and the pilot valve 2 that carries valve on the gas pipeline, described pilot valve is attempted by between the advancing of main valve/air outlet by pipeline, pilot valve by the contrast main valve advance/air outlet between the pressure difference of gas control the folding of main valve; The suction port of described main valve is to being connected with filter 4 and heater 5 in turn by pressure pipe 3 between the suction port of pilot valve valve; Be connected by pipeline between the air outlet of described pilot valve valve and the switch part of main valve 11, the air outlet of main valve is connected with the switch part of pilot valve and main valve respectively by pipeline.Wherein, the pressure of main valve suction port place gas is P1, the pressure of place, main valve air outlet gas is P2, the pressure of place, pilot valve valve air outlet gas is P3, pressure is that the gas of P1 passes through first the filter impurity screening, pass through again the heater heat tracing, last by transferring the gas that pressure is P3 after the step-down of pilot valve valve throttle to, pressure is that the gas of P3 and gas that pressure is P2 carry out the pressure contrast in the switch part of main valve, the switch part of main valve is according to the folding of the comparing result control main valve of P3 and P2, pilot valve is controlled the folding of pilot valve valve according to the pressure P2 that place, main valve air outlet gas feeds back, and then keeps the pressure stability of downstream steam line.
Can install according to actual needs drainage device additional in the above-mentioned filter, to make things convenient for the staff regulator be carried out cleaning.
The model utility principle is simple, practical, by before the pilot valve valve, adding fixed filter and heater, make combustion gas pass through first contaminant filter and heat tracing, input again the pilot valve valve, thereby effectively solve the stifled problem of ice that combustion gas occurs when flowing through the pilot valve valve.Further, ensure the regulator safe operation, reduced the maintenance work to regulator, prolonged life cycle and the life-span of regulator, thus the control technique of having given prominence to energy energy saving optimizing.
Above-described embodiment is better implementation of the present utility model, is not to be to restriction of the present utility model, and under the prerequisite that does not break away from inventive concept of the present utility model, any apparent replacement is all within protection domain of the present utility model.
