Abstract
A natural gas pressure regulating apparatus recovering and reusing high pressure diffused gas is formed by a natural gas pressure regulating main pipeline and a high pressure diffused gas pressure regulating branch pipeline, wherein the two pipelines are in a parallel connection; the natural gas pressure regulating main pipeline comprises a natural gas inlet, an inlet valve, a first coil pipe (a), a filter, a stop valve, a first stage pressure regulator, a second coil pipe (b), a second-stage pressure regulator, a reducing pipe member (b), an outlet valve and a natural gas outlet in a serial-parallel connection way; a pressure transmitter, a safety valve bottom valve and a safety valve are arranged on a pipeline; the high pressure diffused gas pressure regulating branch pipeline consists of a high pressure diffused gas pressure regulator, a reducing pipe member (a) and a solenoid valve in a serial-parallel connection way; and the pressure transmitter is connected with the solenoid valve via a wire. The natural gas pressure regulating apparatus recovering and reusing high pressure diffused gas is advantaged by simple structure, safety, reliability, easy operation, convenient maintenance, economic benefits and strong applicability, thereby being widely suitable for large gas companies, city gate stations, industrial park station buildings and residential quarter station buildings.
Description
(1) technical field
The utility model relates to gas-fired equipment fixture, particularly a kind of natural gas pressure regulating device that reclaims high pressure diffused gas recycling.
(2) background technique
Gas-fired equipment is in actual moving process, because a variety of causes can make the pressure rise in pipeline, in the time that pressure rise arrives the popping pressure of safety valve, safety valve can move, rock gas unnecessary in pipeline is emitted, until the pressure drop of rock gas arrives within the scope of normal working pressure in pipeline.
The rock gas that safety valve jumping up gives off is generally all directly discharged in atmosphere, not only causes waste, the befouling environment of the energy, and allows user suffer economically certain loss.The rock gas wanting diffusing out utilizes, and the rock gas that must have a kind of new system to emit these carries out recycling.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, and the natural gas pressure regulating device of a kind of simple in structure, safe and reliable, easy operating, the recovery high pressure diffused gas recycling that easy to maintenance, economical and practical, applicability is strong is provided.
The technical solution of the utility model:
A kind of natural gas pressure regulating device that reclaims high pressure diffused gas recycling, formed by natural gas pressure regulating main line and high pressure diffused gas pressure regulation bye-pass, natural gas pressure regulating main line comprise Imported gas, inlet valve, heat exchanger coil pipe a, filter, cut-off valve, one-level pressure governor, heat exchanger coil pipe b, second voltage regulation device, reducer pipe fitting b, outlet valve and gas outlet and be connected in series by pipeline, on the pipeline between one-level pressure governor and coil pipe b, be provided with pressure transmitter, safety valve bottom valve and safety valve; High pressure diffused gas pressure regulation bye-pass comprises high pressure diffused gas pressure governor, reducer pipe fitting a and solenoid valve and is connected in series by pipeline, the import of high pressure diffused gas pressure governor is connected with the outlet of safety valve by pipeline, and the outlet of solenoid valve is connected with the inlet pipeline of outlet valve by pipeline; Pressure transmitter is connected with solenoid valve by wire.
Working procedure of the present utility model:
This device is before operation, the bottom valve of safety valve and solenoid valve are in closed condition, high pressure diffused gas pressure governor presets outlet pressure, it is a little more than second voltage regulation device outlet pressure 0.05MPa, solenoid valve and pressure transmitter interlock, the high limit setting value of pressure transmitter is set as consistent with the breakout pressure value of safety valve.In the time that device start normally moves, the bottom valve of safety valve is in normally open, when some parts before rock gas air supply system second voltage regulation break down, while causing pressure rise in the pipeline between one-level pressure governor and second voltage regulation device to the popping pressure of safety valve, safety valve can be opened unnecessary gas emission is fallen, when safety valve is opened, solenoid valve is also opened simultaneously, the gas diffusing out enters into after second voltage regulation device in pipeline after the pressure regulation of high pressure diffused gas pressure governor, is recovered in natural gas supply pipe-line system.
The utility model has the advantages that: this apparatus structure is simple, safe and reliable, easy operating, easy to maintenance, economical and practical, applicability is strong, can be widely used in door station, industrial park station and the residential quarter station in large-scale gas company, city.
