Description
Technical field
The utility model belongs to natural gas pressure regulating device technique field, specifically a kind of Gas Pressure Regulating Equipment adopting the uninterrupted air feed of monitoring guarantee in parallel.
Background technique
Along with rapid development of economy, be that the situation day of the energy is becoming tight with oil.The fuel of people's productive life no longer only depends on coal, wet goods fuel, and rock gas becomes rapidly main flow fuel as the new energy of cleanliness without any pollution.The too high high pressure of natural gas via of long-distance transport pipes, high pressure station enter urban pipe network, so the function of voltage regulating station is except metering, pressure regulation, most important is exactly ensure uninterrupted air feed, because once stop the supple of gas or steam, directly will affect end user, particularly industrial user is hundreds thousand of down to economic loss up to a million by causing.So in order to address this problem, this just needs a kind of Gas Pressure Regulating Equipment adopting the uninterrupted air feed of monitoring guarantee in parallel.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of Gas Pressure Regulating Equipment adopting the uninterrupted air feed of monitoring guarantee in parallel.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of Gas Pressure Regulating Equipment adopting the uninterrupted air feed of monitoring guarantee in parallel, the inlet ductwork of this device is provided with inlet pressure gauge, it is characterized in that: this device described comprises two line structure identical working ways pressure regulation pipelines and monitoring road pressure regulation pipeline, after the inlet ball valve that each road pressure regulation pipeline connects successively by high pressure pipe line, cartridge filter, Emergeny Cutoff Valves, Emergeny Cutoff Valves pressure pipe, pressure governor, pressure governor pressure pipe, atmospheric valve, pressure regulation, after pressure gauge and pressure regulation, ball valve is formed.
And, the model that described inlet ball valve adopts is: Q41F-16C DN100, the model that described cartridge filter adopts is: HGL-100 PN16 filter precision 50 μ, the model that described Emergeny Cutoff Valves adopts is: RAQ-50 PN16, Emergeny Cutoff Valves pressure pipe is φ 10mm, the model that described pressure governor adopts is: AFV-50 CLASS300, pressure governor pressure pipe is φ 10mm, the model that described atmospheric valve adopts is Q11F-64P DN15, the model that after described pressure regulation, ball valve adopts is: Q341F-16C DN150, described inlet pressure gauge model is Y1000-0.6MPa, after pressure regulation, pressure gauge model is Y100-10KPa.
Advantage of the present utility model and good effect are:
In the utility model device, two-way pressure regulation pipeline adopts monitoring form in parallel, and when work pressure governor breaks down, outlet pressure is raised, the emergency cut-off valve events of main road, cuts off gas circuit.Due to the impact of downstream user gas, downstream pressure drops to the driving pressure of monitoring pressure governor, and monitoring pressure governor is opened and started working, and outlet pressure is a little less than former outlet pressure thus realize two-way pressure regulation and automatically switch, and ensures the uninterrupted air feed of gas pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of Gas Pressure Regulating Equipment adopting the uninterrupted air feed of monitoring guarantee in parallel, as shown in Figure 1, the inlet ductwork of this device is provided with inlet pressure gauge 10, this device described comprises two line structure identical working ways pressure regulation pipelines and monitoring road pressure regulation pipeline, and after the inlet ball valve 1 that each road pressure regulation pipeline connects successively by high pressure pipe line, cartridge filter 2, Emergeny Cutoff Valves 3, Emergeny Cutoff Valves pressure pipe 4, pressure governor 5, pressure governor pressure pipe 6, atmospheric valve 7, pressure regulation, after pressure gauge 8 and pressure regulation, ball valve 9 is formed.
As instantiation of the present utility model, the model that described inlet ball valve adopts is: Q41F-16C DN100, the model that described cartridge filter adopts is: HGL-100 PN16 filter precision 50 μ, the model that described Emergeny Cutoff Valves adopts is: RAQ-50PN16, Emergeny Cutoff Valves pressure pipe is φ 10mm, the model that described pressure governor adopts is: AFV-50 CLASS300, pressure governor pressure pipe is φ 10mm, the model that described atmospheric valve adopts is Q11F-64P DN15, the model that after described pressure regulation, ball valve adopts is: Q341F-16C DN150, described inlet pressure gauge model is Y1000-0.6MPa, after pressure regulation, pressure gauge model is Y100-10KPa.
Working principle
When this regulator normally runs, first the inlet ball valve of working ways pressure regulation pipeline is slowly opened, mouth pressure P1 is adjusted by work pressure governor, close the inlet ball valve of working ways pressure regulation pipeline again, then slowly open the inlet ball valve of monitoring road pressure regulation pipeline, adjust mouth pressure P2 by monitoring pressure governor, then the front and back valve on working ways and pressure regulation road is all opened, when work pressure governor breaks down, outlet pressure P1 is raised, the emergency cut-off valve events of main road, cuts off gas circuit.Due to the impact of downstream user gas, downstream pressure drops to the driving pressure of monitoring pressure governor, and monitoring pressure governor is opened and started working, and outlet pressure P2 is a little less than former outlet pressure P1.
