Abstract
The utility model relates to a device is diffused to dual fail -safe safety, including the voltage regulator, with main line after the pressure regulating of voltage regulator exit linkage, be connected with the emptying pipeline who takes the unloading ball valve on the main line after the pressure regulating of voltage regulator export, it has main relief valve and reserve relief valve to connect in parallel between the emptying pipeline in main line after the pressure regulating of voltage regulator export and unloading ball valve low reaches, the specification of main relief valve and reserve relief valve is the same, has all concatenated the relief valve ball valve on the inlet pipe of main relief valve and reserve relief valve. The utility model discloses flow among the device is diffused to dual fail -safe safety sets up simply, compact structure, convenient to use, little, the easy maintenance of investment operation and safe and reliable, and two relief valves can make the manifold pressure recover normal operating pressure rapidly to two relief valves have constituted one division one structure that is equipped with, and each other is reserve, the safety of assurance equipment under incessant air feed.
Description
Technical field
The utility model belongs to the equipment technical field of diffusing in the various pressure regulation such as compressed natural gas pressure-reducing gas, door station, mixed gas, concreteIt is a kind of Double-protective safety bleeding device.
Background technology
The material and the environmental protection needs that day by day improve along with increasing and the people of China's natural gas exploration and development dynamics, in recent years,Long-distance Transmission Pipeline and large-scale door station and the development of all kinds of voltage adjusting device are very rapid, and at Compressed natural gas pressure regulator device or door stationIn voltage adjusting device, for ensureing device security, after pressure regulator, safety valve must be set, and we tend in pressure regulationA safety valve is set after device, also there is potential safety hazard in setting like this, because if in use procedure safety valve damage orNot take-off, we are ignorant, even in the time that safety valve is taken annual test away, in the whole process of annual test, equipment is without safetyIn the situation of device, what move, there is larger potential safety hazard in equipment so, therefore, one is set after pressure regulationSafety valve is very important.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of Double-protective safety bleeding device.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of Double-protective safety bleeding device, comprises pressure regulator, export with pressure regulator the pressure regulation being connected after main line, at pressure regulatorAfter the pressure regulation of outlet, on main line, be connected with the exhausting pipeline with emptying ball valve, main line and emptying after the pressure regulation of pressure regulator outletBetween the exhausting pipeline in ball valve downstream, be parallel with main safety valve and safety valve for subsequent use.
And the specification of described main safety valve and safety valve for subsequent use is identical.
And, on the inlet duct of main safety valve and safety valve for subsequent use, be all serially connected with safety valve ball valve.
Advantage of the present utility model and good effect are:
1, simple, the compact conformation of the flow setting in the utility model Double-protective safety bleeding device, easy to use, invest little,For ease of maintenaince operation and safe and reliable;
2, the utility model, by two safety valves are set on main line after pressure regulation, can make manifold pressure just return to rapidlyOften operating pressure, and two safety valves has formed one and has opened a standby structure, for subsequent use each other, and guarantee equipment is under uninterrupted air feedSafety.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
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 Double-protective safety bleeding device, as shown in Figure 1, comprises pressure regulator 1, leads after export the pressure regulation being connected with pressure regulatorPipeline 7 is connected with the exhausting pipeline 5 with emptying ball valve 2, wound of the present utility model on main line after the pressure regulation of pressure regulator outletNew point is between main line and emptying ball valve downstream exhausting pipeline, to be parallel with main safety valve 3 and standby after the pressure regulation of pressure regulator outletWith safety valve 4.
In concrete enforcement of the present utility model, the specification of described main safety valve and safety valve for subsequent use is identical.
In concrete enforcement of the present utility model, on the inlet duct of main safety valve and safety valve for subsequent use, be all serially connected with safe valve ballValve 6.
Operation principle
And two safety valves have the identical pressure that diffuses, one opens one standbyly, and when a safety valve breaks down, another can also continueWork, ensures device security.
