The utility model provides the high security performance of natural gas equipment, it can not the automatic instantaneous function of diffusing of superpressure pipeline to have realized, and user convenient to use, safe and reliable are respond well.

Description

A kind of three valve group safe diffusion devices
Technical field
The utility model belongs to natural gas skid mounted equipment technical field, particularly a kind of three valve group safe diffusion devices.
Background technology
The more common safety mode of diffusing in current natural valve station is that under safety valve, choke stop evacuation valve is connected with flanged ball valve,Manually opened choke stop evacuation valve is realized and being diffused.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, can realize and can not realize automatic wink by superpressure pipeline and propose oneTime the three valve group bleeding devices that diffuse.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of three valve group safe diffusion devices, comprise natural gas main pipeline, and various gas-fired equipments are installed on natural gas main pipeline,On the natural gas main pipeline of various gas-fired equipment front ends, preposition magnetic valve is installed, the natural gas supervisor of various gas-fired equipments rear endRearmounted magnetic valve is installed on road, on the natural gas main pipeline between preposition magnetic valve and rearmounted magnetic valve, is installed by diffuse channelDiffuse magnetic valve, on the natural gas main pipeline between preposition magnetic valve and rearmounted magnetic valve, pressure transmitter is installed, pressureThe data terminal of transmitter is connected with external control device, meanwhile, and preposition magnetic valve, rearmounted magnetic valve and the control of diffusing magnetic valveEnd is connected with external control device, and gather and show the pressure data on natural gas main pipeline by external control device, meanwhile, controlMake preposition magnetic valve, rearmounted magnetic valve and diffuse the on off state of magnetic valve.
And described external control device comprises the display screen for showing pressure data and controls preposition magnetic valve, rearmounted electromagnetismValve and diffuse the control module of electromagnetic valve switch state.
And described control module is a digital comparator.
And described control module is one group of chopper switch.
Advantage of the present utility model and good effect are:
1, the utility model device adopts the mode that three valve groups act on simultaneously, has improved the security performance of natural gas facility, has realizedCan not superpressure pipeline instantaneous function of diffusing automatically.
2, the utility model compact conformation, strong adaptability, user is esy to use, safe and reliable, respond well.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is implemented to be further described, following examples are descriptive, are not limited, can not limit protection domain of the present utility model with this.
A kind of three valve group safe diffusion devices, as shown in Figure 1, comprise natural gas main pipeline 1, on natural gas main pipeline, installHave various gas-fired equipments 6, innovative point of the present utility model is, before installing on the natural gas main pipeline of various gas-fired equipment front endsPut magnetic valve 2, rearmounted magnetic valve 8 is installed on the natural gas main pipeline of various gas-fired equipments rear end, in preposition magnetic valve and postpositionOn natural gas main pipeline between magnetic valve, be provided with and diffuse magnetic valve 4 by diffuse channel 3, at preposition magnetic valve and rearmounted electricityOn natural gas main pipeline between magnet valve, pressure transmitter 5 is installed, the data terminal of pressure transmitter and external control device 7 connectConnect, meanwhile, preposition magnetic valve, rearmounted magnetic valve and the control end that diffuses magnetic valve are connected with external control device, are controlled by outsideDevice collection processed also shows the pressure data on natural gas main pipeline, controls preposition magnetic valve, rearmounted magnetic valve simultaneously and diffuses electricityThe on off state of magnet valve.
In concrete enforcement of the present utility model, described external control device comprises display screen and the control for showing pressure dataPreposition magnetic valve, rearmounted magnetic valve and diffuse the control module of magnetic valve.
In concrete enforcement of the present utility model, described control module is a digital comparator, in digital comparator, is provided withThe limiting pressure numerical value of natural gas main pipeline, the pressure value once the pressure value of natural gas main pipeline oversteps the extreme limit, comparator willOutput signal, controls preposition magnetic valve and rearmounted solenoid closure, and control is diffused magnetic valve and opened.
In concrete enforcement of the present utility model, the simplest, described control module is one group of banister switch, staff's rootThe state conversion that the pressure data control banister switch of screen completes preposition magnetic valve, rearmounted magnetic valve and diffuses magnetic valve according to the show.
Working procedure of the present utility model:
Natural gas main pipeline comes before gas, and three magnetic valves are in off-position, and two main pipeline normally open solenoid valves are opened, and diffuse channel is normalClose closed electromagnetic valve. In the time passing into natural gas, natural gas can carry out respective handling by the equipment in main pipeline, when controllingWhen unit shows superpressure, realize main pipeline by magnetic valve and close and the unlatching of diffuse channel magnetic valve, reach letting out of natural gas main pipelinePress, to protect the safe handling of natural gas main pipeline.
