Description

A kind of wafer type filter device for CNG pressure regulation metering pipelines
Technical field
The utility model belongs to compressed natural gas pressure regulating gas control device technical field, specifically a kind of based on CNG pressure regulation The wafer type filter device on buret road.
Background technology
Filter before current CNG (Compressed Natural Gas) pressure regulating metering device flowmeter mainly uses Y-type filter and cartridge filter, both filters are installed in pipeline external, and with the increase of equipment flow, mistake The size of filter also will increase, and installation process needs to consider the installation space of other vigour parts of equipment and consider later Dismounting and maintenance, the filter core cost of both filters are higher.Considerably increase CNG pressure regulating metering devices cost and safeguard at This.
Invention content
The purpose of this utility model is in view of the deficiencies of the prior art, and to propose a kind of for CNG pressure regulation metering pipelines Wafer type filter device.
The utility model solves its technical problem and following technical scheme is taken to realize:
A kind of wafer type filter device for CNG pressure regulation metering pipelines includes pipeline valve on CNG pressure regulation metering pipelines Door and pipeline flowmeter, installation is by outlet(discharge) flange on the export pipeline of pipe valve, on the entrance pipe of pipeline flowmeter The inlet flange docked with outlet(discharge) flange is installed, folder is equipped between outlet(discharge) flange and inlet flange and is placed in pipe valve Wafer type filter core inside export pipeline is being equipped with blowdown valve, to folder close to the bottom of wafer type filter core air inlet lateral line Differential pressure gauge is installed between formula filter core air inlet side and outlet lateral line.
Moreover, being equipped with imported valve a on the air inlet lateral line of differential pressure gauge, installed on the outlet lateral line of differential pressure gauge There is outlet valve b.
The advantages of the utility model and good effect are:
1, the utility model is mounted on inside pipeline, is not had an impact to equipment other components installation.
2, the utility model is simple in structure, and cost and maintenance cost are low.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model implementation is further described below in conjunction with attached drawing, following embodiment is descriptive, is not Limited, protection scope of this utility model cannot be limited by this.
A kind of wafer type filter device for CNG pressure regulation metering pipelines, as shown in Figure 1, on CNG pressure regulation metering pipelines Including pipe valve 1 and pipeline flowmeter 7, the innovative point of the utility model is installed out on the export pipeline of pipe valve Mouthful flange 9 installs the inlet flange 8 docked with outlet(discharge) flange on the entrance pipe of pipeline flowmeter, outlet(discharge) flange with enter The wafer type filter core 3 being placed in inside pipe valve export pipeline is equipped with to folder between mouthful flange, close to wafer type filter core into The bottom of gas side pipeline is equipped with blowdown valve 2, the dirt for being blocked in wafer type filter core front end is discharged, wafer type filter core into Differential pressure gauge 5 is installed, to detect the working condition of wafer type filter core between gas side and outlet lateral line.
In the specific implementation of the utility model, imported valve a4 is installed on the air inlet lateral line of differential pressure gauge, in difference Outlet valve b6 is installed on the outlet lateral line of pressure table, keeps the installation of differential pressure gauge, repair more convenient.
The utility model proposes wafer type filter device is used in CNG pressure regulating metering devices, this device is will to filter Net is mounted in pipeline, is filtered to the gas in pipeline.This mounting means without consider from the front and back straight tube of flowmeter to The influence to filter device of other components when being installed with equipment, and this device is equipped with differential pressure gauge, when the impurity in pipeline When being had an impact to gas flow, the sewage draining valve of opening conduits can remove pipeline impurity, when filter device breaks down It only needs to change to pressing from both sides filter core, safeguards that simply cost is relatively low.
The utility model is mounted on inside pipeline, is not had an impact to equipment other components installation.
The utility model is simple in structure, and cost and maintenance cost are low.
