Abstract
The invention relates to the technical field of natural gas pipeline transportation equipment, in particular to a natural gas meandering flow pressure regulator applicable to gate stations and distribution stations of a natural gas system as well as can be used for regional pressure regulation and user regulation. The natural gas meandering flow pressure regulator comprises a main regulator and a director. A pressure guide tube is connected between the main regulator and the director. The main regulator is installed on a natural gas transmission pipeline. The natural gas meandering flow pressure regulator is reasonable in design and has the advantages of being compact in structure, stable in performance, wide in pressure regulation range, tight in closing, low in running noise, high in sensitivity, good in pressure regulation performance and the like.
Description
Technical field
The present invention relates to gas pipeline conveying equipment technical field, especially a kind of door station, distribution station being applicable to natural gas system, also can be used for the rock gas meander formula pressure governor of region pressure regulation and user's pressure regulation.
Background technique
Pressure governor refers in gas conveying system and claims for pressure controlled equipment.Pressure governor is that higher inlet pressure is adjusted to lower outlet pressure, and need automatically control outlet pressure in a certain setting value with the change of operating mode along with rock gas.Traditional pressure governor complex structure, air-flow directly impacts on film, and film is fragile, and working life is short, have impact on voltage regulation result.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the rock gas meander formula pressure governor that voltage regulation result is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rock gas meander formula pressure governor, comprise master selector and pilot valve, PRESSURE PIPE is connected with between master selector and pilot valve, master selector is arranged on natural gas transport pipeline, described master selector comprises main voltage regulator valve body and main voltage regulator valve gap, main voltage regulator valve body is built-in with main voltage regulator rubber sleeve, main voltage regulator rubber sleeve inwall is vertically provided with main voltage regulator spool, and gas pipeline is divided into inlet ductwork and export pipeline by main voltage regulator spool; Described pilot valve comprises pilot valve lower shell body and pilot valve upper shell, and pilot valve upper shell is built-in with pilot valve spring, and pilot valve spring one end is fixed on pilot valve spring inwall, and the pilot valve spring the other end is connected with pilot valve film; Described pilot valve lower shell body is built-in with pilot valve valve rod, and pilot valve valve rod two ends are provided with pilot valve spool, and pilot valve lower shell body is provided with give vent to anger valve port and intake valve port.
Further, described pilot valve lower shell body is provided with aperture, and main voltage regulator valve body is provided with annular chamber, is connected with PRESSURE PIPE between aperture and annular chamber.
Further, described pilot valve lower shell body is provided with PRESSURE PIPE entrance, and PRESSURE PIPE entrance is connected to export pipeline by PRESSURE PIPE.
Further, described valve port and the intake valve port of giving vent to anger is connected to master selector by PRESSURE PIPE.
Further, described main voltage regulator spool is oval metal plate.
Rock gas flows into from the inlet ductwork of main voltage regulator, through main voltage regulator spool suction side vent cap, flows through the cavity between main voltage regulator rubber sleeve, then through main voltage regulator spool outlet side vent cap, flows out from export pipeline.When inlet ductwork pressure reduces or load increases, export pipeline pressure is lower than setting value, and the pressure acted on pilot valve film reduces, under the effect of pilot valve spring, the downward side of pilot valve valve rod is moved, intake valve port aperture reduces, and exhaust valve port aperture increases, and pilot valve pressure is reduced, the spacing of main voltage regulator rubber sleeve and main voltage regulator spool increases, flow increases, and export pipeline pressure raises, and returns to setting value.When inlet ductwork pressure raises or load reduces, export pipeline pressure is higher than setting value, then adjustment process is reversed.
The invention has the beneficial effects as follows: the present invention is reasonable in design, have compact structure, stable performance, range of regulation wide, close tight, running noises is little, highly sensitive, the features such as pressure regulating performance is good.
