Description
Technical field
The utility model belongs to natural gas pressure regulating device technique field, specifically a kind of Gas Pressure Regulating Equipment adopting series connection monitoring.
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 series connection monitoring to ensure uninterrupted air feed.
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 series connection monitoring.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of Gas Pressure Regulating Equipment adopting series connection monitoring, comprise the road series voltage-regulating pipeline be arranged on after inlet and outlet pressure table, the inlet ball valve that a described road series voltage-regulating pipeline is connected successively by gas pipeline, inlet pressure gauge, monitoring pressure governor, work pressure governor, atmospheric valve, after pressure regulation, after pressure gauge and pressure regulation, ball valve is formed, the pressure point of described work pressure governor air inlet pressure pipe is arranged on the left side gas pipeline before the import of monitoring pressure governor, described monitoring pressure governor the give vent to anger pressure point of pressure pipe of the pressure point of pressure pipe and work pressure governor of giving vent to anger all is placed on the gas pipeline between work pressure governor and atmospheric valve.
And, the model that described inlet ball valve adopts is: Q41F-16C DN80, the model that described monitoring pressure governor and work pressure governor all adopt is: AFV-50 CLASS300, the model that the pressure pipe of pressure governor is φ 10mm, described atmospheric valve adopts is Q11F-64P DN15, the model that after described pressure regulation, ball valve adopts is: Q41F-16C DN100, described inlet pressure gauge model is Y100 0-1.6MPa, and after pressure regulation, pressure gauge model is Y100-0.6MPa.
Advantage of the present utility model and good effect are:
In the utility model device, a road pressure regulation pipeline adopts series connection monitoring form, the pressure setting of monitoring pressure governor is all a little more than work pressure governor, so when work voltage regulator operation time, monitoring pressure governor is in full-gear, when work pressure governor breaks down the critical value of pressure setting causing downstream pressure to be elevated to monitoring pressure governor, monitoring pressure governor pilot pressure raises, turn down valve port, to start working pressure regulation, outlet pressure will a little more than former outlet pressure, like this, even if work pressure governor damages, monitoring pressure governor can be opened automatically, thus ensure 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 series connection monitoring, as shown in Figure 1, comprise the road series voltage-regulating pipeline be arranged on after inlet and outlet pressure table, the inlet ball valve 1 that a described road series voltage-regulating pipeline is connected successively by gas pipeline, inlet pressure gauge 2, monitoring pressure governor 4, work pressure governor 5, atmospheric valve 8, after pressure regulation, after pressure gauge 9 and pressure regulation, ball valve 10 is formed, the pressure point of described work pressure governor air inlet pressure pipe 3 is arranged on the left side gas pipeline before monitoring pressure governor, to ensure the interference of the not monitored pressure governor of pressure, described monitoring pressure governor the give vent to anger pressure point of pressure pipe 6 of the pressure point of pressure pipe 7 and work pressure governor of giving vent to anger all is placed on the gas pipeline between work pressure governor and atmospheric valve.
As instantiation of the present utility model, the model that described inlet ball valve adopts is: Q41F-16C DN80, the model that described monitoring pressure governor and work pressure governor all adopt is: AFV-50 CLASS300, the model that the pressure pipe of pressure governor is φ 10mm, described atmospheric valve adopts is Q11F-64P DN15, the model that after described pressure regulation, ball valve adopts is: Q41F-16C DN100, described inlet pressure gauge model is Y100 0-1.6MPa, and after pressure regulation, pressure gauge model is Y100-0.6MPa.
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 monitoring pressure governor, and then regulating the outlet pressure P2 of work pressure governor, P2 is a little less than P1, and then pressure regulation late gate is opened, when work pressure governor breaks down the critical value of pressure setting causing downstream pressure to be elevated to monitoring pressure governor, monitoring pressure governor pilot pressure raises, and turns down valve port, pressure regulation of starting working.Outlet pressure will a little more than former outlet pressure.
