Abstract
Pressure after the utility model relates to a kind of natural gas pressure regulating on pipeline is with dividing an air bag unit, comprise on the natural gas line after being welded on pressure regulation, the seamless steel pipe be communicated with natural gas line, seamless steel pipe two side is provided with multiple high pressure discount side by side, at the port of each high pressure discount, screw thread ball valve is all installed, be installed with pipe cap on the top of seamless steel pipe, have pressure gauge at the top of pipe cap by the Pipe installing being provided with Gauge Valves.The flow setting of the utility model device is simple, compact structure, easy to use, the size of straight length after pressure regulation can be effectively reduced, make equipment compacter, attractive in appearance, and facilitate the installation of staff.
Description
Technical field
The utility model belongs to natural gas line device technique field after large-scale door station pressure regulation, point air bag unit of the pressure specifically after a kind of natural gas pressure regulating on pipeline.
Background technique
The material day by day improved along with increasing and the people of China's natural gas exploration and development dynamics and environmental protection needs, in recent years, the development at Long-distance Transmission Pipeline and large-scale door station is very rapid, but, due to the cut-off valve at the large-scale door station of rock gas, pressure governor all needs more rear pressure tappings, therefore just need the natural gas line after pressure regulation opens thickly dotted pressure-taking hole and pressure gauge hole, sometimes pressure-taking hole need be opened in pipeline side to save space, so cause staff cumbersome at connection signal Guan Shihui, and signal tube intersects also unsightly after connecting, so, after natural gas pressure regulating, pipeline is installed a pressure point air bag unit and just seem very necessary.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and the pressure after proposing a kind of natural gas pressure regulating on pipeline is with dividing an air bag unit.
The utility model solves its technical problem and takes following technological scheme to realize:
Pressure after a kind of natural gas pressure regulating on a pipeline point air bag unit, comprise on the natural gas line after being welded on pressure regulation, the seamless steel pipe be communicated with natural gas line, seamless steel pipe two side is provided with multiple high pressure discount side by side, at the port of each high pressure discount, screw thread ball valve is all installed, be installed with pipe cap on the top of seamless steel pipe, have pressure gauge at the top of pipe cap by the Pipe installing being provided with Gauge Valves.
And, for specification be BM5 cut-off valve, FL pressure governor and specification be
natural gas line, the aperture specification of described seamless steel pipe is DN50.
And, the described multiple high pressure discounts installed side by side for being welded on seamless steel pipe both sides, the high pressure discount of two side by side up and down of every side.
Advantage of the present utility model and good effect are:
1, the flow setting in the utility model pressure obtaning device is simple, compact structure, easy to use, invest little, attractive in appearance and safe and reliable;
2, the utility model is by the setting of release valve ball on large size valve, and after can effectively reducing pressure regulation, straight length size makes equipment compacter, attractive in appearance, and facilitates the installation of staff.
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.
Pressure after a kind of natural gas pressure regulating on a pipeline point air bag unit, as shown in Figure 1, comprise and to be welded on after pressure regulation on natural gas line, the seamless steel pipe 5 be communicated with natural gas line, seamless steel pipe two side is provided with multiple high pressure discount 1 side by side, at the port of each high pressure discount, screw thread ball valve 6 is all installed, the delivery outlet of each screw thread ball valve is as the pressure tappings on pipeline after natural gas pressure regulating, be installed with pipe cap 4 on the top of seamless steel pipe, have pressure gauge 2 at the top of pipe cap by the Pipe installing being provided with Gauge Valves 3.
In concrete enforcement of the present utility model, as shown in Figure 1, the natural gas line after described pressure regulation is the pipeline in cut-off valve and pressure governor downstream, for specification be BM5 cut-off valve, FL pressure governor and specification be
pipeline, the aperture specification of described seamless steel pipe is DN50.
In concrete enforcement of the present utility model, the described multiple high pressure discounts installed side by side for being welded on seamless steel pipe both sides, the high pressure discount of two side by side up and down of every side.
The utility model, by together integrated in the past independent pressure tappings stage pressure table mouth, forms this device, and then after pressure regulation, on pipeline, correct position welds this device.
