Abstract
The invention provides a natural gas filter device which comprises a valve body, an inlet connection piece, an outlet connection piece, a dirt discharging nozzle and a filter screen, wherein the valve body comprises a natural gas inlet and a natural gas outlet which are perpendicular to each other; the inlet connection piece is in seal connection with the natural gas inlet; the outlet connection piece is in seal connection with the natural gas outlet; one end of the outlet connection piece extends into the valve body; the filter screen is arranged at the end, extending into the valve body, of the outlet connection piece; the dirt discharging nozzle is arranged on the valve body. The natural gas filter device has the benefits that the filter screen is more convenient to replace, the structure is simple, the processing cost is low, and relatively high pressure can be borne.
Description
Technical field
The invention belongs to natural-gas transfer pipeline apparatus field, especially relate to a kind of natural gas filter.
Background technology
Natural-gas transfer pipeline needs the filter be provided with for filtering natural gas impurity, to remove solid particle polluter in natural gas and moisture content, ensure that the drying of source of the gas is with clean, so just can enter user pipe to use, in existing technology natural gas filter comprise a upper end open cylindrical shell, be placed in the filter core in cylindrical shell and the sealing device for sealed open, Imported gas and gas outlet are relatively arranged on the sidewall of cylindrical shell.There is the technical problems such as complex structure, cost of manufacture is high, load performance is poor, filter element replacing is inconvenient.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of natural gas filter, and its structure is simple, cost of manufacture is low, load performance is good, more renew cartridge is convenient.
For solving the problems of the technologies described above, the technical solution used in the present invention is: natural gas filter, comprise valve body, inlet connection, outlet connector, blowdown mouth and filter screen, described valve body comprises an Imported gas and a gas outlet, described Imported gas and gas outlet are mutually vertical to be arranged, described inlet connection and Imported gas are tightly connected, described outlet connector and gas outlet are tightly connected, and outlet connector one end is stretched in valve body, the one end stretching into the outlet connector in valve body is provided with described filter screen, described blowdown mouth is arranged on valve body.
Further, described valve body comprises a hollow cylinder, and the stifled sealing of a underrun valve of described valve body, another bottom surface of valve body is gas outlet, and the sidewall of described valve body is provided with a circular Imported gas.
Further, described inlet connection comprises a hollow cylinder, and described inlet connection is welded on the circular Imported gas of described body wall, and one end that described inlet connection is positioned at outside valve body is provided with external screw thread.
Further, described outlet connector comprises a hollow cylinder, described hollow cylinder outer wall is provided with valve gap, described valve gap is provided with at least two through holes, the valve body bottom surface of described gas outlet is provided with the screwed hole coordinated with valve gap through hole, valve gap is tightly connected by bolt and gas outlet, and one end that described outlet connector is positioned at outside valve body is provided with external screw thread.
Further, described screen pack is protruding to valve inner, and screen pack is fixed on outlet connector one end by pressure ring.
Further, described screen pack is double-layer filtering net.
Further, described blowdown mouth arranges below filter screen, and blowdown mouth is sealed by sealing bolt.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, change filter screen convenient; There is structure simple, the advantages such as processing cost is low, production efficiency is high, load performance is good.

Detailed description of the invention
As shown in Figure 1, 2, natural gas filter of the present invention, comprise valve body 1, inlet connection 2, outlet connector 3, blowdown mouth 4 and filter screen 5, valve body 1 comprises an Imported gas and a gas outlet, Imported gas and gas outlet are mutually vertical to be arranged, inlet connection 2 and Imported gas are tightly connected, outlet connector 3 and gas outlet are tightly connected, and outlet connector 3 one end is stretched in valve body 1, the one end stretching into the outlet connector 3 in valve body 1 is provided with filter screen 5, and blowdown mouth 4 is arranged on valve body 1; Valve body 1 comprises a hollow cylinder, stifled 6 sealings of a underrun valve of valve body 1, and another bottom surface of valve body 1 is gas outlet, and the sidewall of valve body 1 is provided with a circular Imported gas; Inlet connection 2 comprises a hollow cylinder, and inlet connection 2 is welded on the circular Imported gas of valve body 1 sidewall, and one end that inlet connection 2 is positioned at outside valve body 1 is provided with external screw thread; Outlet connector 3 comprises a hollow cylinder, hollow cylinder outer wall is provided with valve gap 7, valve gap 7 is provided with at least two through holes 11, valve body 1 bottom surface of gas outlet is provided with the screwed hole 12 coordinated with valve gap 7 through hole 11, valve gap 7 is tightly connected by bolt 9 and gas outlet, and one end that outlet connector 3 is positioned at outside valve body 1 is provided with external screw thread; Screen pack 5 is to valve body 1 internal protrusion, and screen pack 5 is fixed on outlet connector 3 one end by pressure ring 8; Screen pack 5 is double-layer filtering net 5; Blowdown mouth 4 is arranged on below filter screen 5, and blowdown mouth 4 is sealed by sealing bolt 10.
The course of work of this example: high-pressure gaseous natural gas enters filter interior from inlet connection 2, filter horizontally through filter screen 5 after baffling, clean natural gas is discharged by outlet connector 3, impurity and particle be less than 10 microns be filtered out, be deposited to below sewage draining exit under gravity, got rid of by blowdown mouth 4.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
