Abstract
The invention discloses a natural gas filter belonging to a natural gas pipe filtering device used in a petroleum collection and transmission engineering such as a natural gas field, a fuel gas transmission and distribution and pressure-regulating system and city gate stations and so on. The natural gas filter comprises a cylinder with an opening on the upper part, a filtering core arranged in the cylinder and a closed mechanism used for sealing an opening. The cylinder is provided with a feed gas inlet, a purified gas outlet and a drain, the upper end of the filtering core is close to the opening, the lower end of the filtering core is communicated with the detergent gas outlet. The natural gas filter is characterized in that the closed mechanism comprises a hub which is extendedly arranged on the top of the cylinder, a sealing cover, a quartered ring, a protecting cover and a fixing screw. The natural gas filter has the advantages that an opening vessel is rapid and convenient, time and labor-saving and cost-saving; the closed mechanism is provided with a self-locking structure, which uses the self-pressure of natural gas to prop up the sealed cover which is sealed with the hub through an O-shaped ring, the quartered ring props up the protection cover so as to meet the requirement of sealing; moreover, the sealing performance is excellent, the leakage of the vessel is prevented and the occurrence of accidents is reduced.
Description
Technical field
The present invention relates to a kind of natural gas filter, belong to natural gas line filtrating equipment in the oil gathering engineerings such as gas field, gas transmission and distribution voltage-regulating system, urban gate station, be used for removing the solid particle polluter and the moisture content of rock gas.
Background technique
The rock gas that contains various solid particle polluters and moisture content at first will filter before use,, so just can enter user pipe and use with clean with the drying that guarantees source of the gas.Natural gas filter structure in the prior art is disclosed by Fig. 1, it comprises that a top (head) has the cylindrical shell 1 of opening 11, place the filter core 2 in the cylindrical shell 1, with the closure mechanism that is used for sealed open 11, described cylindrical shell 1 is provided with raw material gas inlet 12, clean gas outlet 13, sewage draining exit 14, the upper end of described filter core 2 extends to and is close to opening 11 positions, the lower end of filter core 2 is connected with clean gas outlet 13, and described closure mechanism comprises the flange 15 that extends on cylindrical shell 1 outer wall and be positioned at opening 11 places, by some groups of bolt assemblies (by bolt, nut constitutes) 9 with the fixing blind flange 8 of flange 15, and be located at gasket seal 7 between flange 15 and the blind flange 8.The problem that closure mechanism in the said structure exposes in actual use is: because after adopting the Placement of flange, blind flange, bolt assembly, at every turn more during renew cartridge, need many people's operations, spend great amount of manpower and financial resources.With 3.0 type filters is example, change that filter core is minimum wants 3 people's operations, approximately need cost just can finish in 2 hours, and, whenever change filter core one time, gasket seal between flange and the blind flange need be changed once, and the cost of gasket seal 30 yuan/only, total renewal cost is approximately wanted 800 yuan/platform.To change with annual nearly 5000 needs in the whole nation, renewal cost is about 4,000,000/time.And every filter generally needed to change 2-3 time in 1 year, and approximately overall cost takes 8,000,000～1,200 ten thousand yuan/year, has just wasted great amount of manpower and material resources, financial resources.
Summary of the invention
The objective of the invention is to provide a kind of more renew cartridge convenient, fast, both saved time, laborsaving, save cost again, and closure mechanism has the self-locking structure, good seal performance, safe and reliable natural gas filter.
The objective of the invention is to reach like this, a kind of natural gas filter, it comprises that a top has the cylindrical shell of opening, place the filter core in the cylindrical shell, with the closure mechanism that is used for sealed open, described cylindrical shell is provided with raw material gas inlet, clean gas outlet, sewage draining exit, the upper end of described filter core extends to and is close to the aperture position place, the lower end of filter core is connected with clean gas outlet, be characterized in: described closure mechanism comprises the hub that extends in the cylindrical shell top, sealing cover, four fens rings, protecting cover, and set screw, on the inwall of described hub, offer four fens ring draw-in grooves from top to bottom, the sealing cage; Described sealing cover places on the sealing cage, is installed with a double-screw bolt at the nearly medium position place of sealing cover; Described four minutes rings place the top of sealing cover, with four fens ring draw-in groove scarves, are formed with annular distance in the centre of four fens rings; Described protecting cover places the top of four fens rings and joins with the outer rim wall body of hub lid, offers screw in the centre of protecting cover, extends a location collar that is used for the annular distance build-in in the bottom center of protecting cover; Described set screw is rotated with bolt after passing screw.
The present invention also offers o-ring groove on the inwall of described hub, be embedded in a seal ring at o-ring groove, and the outer circle wall of seal ring and sealing cover closely cooperates.
Seal ring of the present invention is the O RunddichtringO.
Ring was to piece together ring bodies by a pair of first ring body and a pair of second ring body in four minutes of the present invention, and wherein: a pair of second ring body can move in annular distance.
The shape of a pair of first ring body of the present invention is identical, and is positioned at the outside of ring bodies, is with respect to annular distance to be symmetrical arranged.
The shape of a pair of second ring body of the present invention is identical, and is positioned at the centre of ring bodies, is with respect to annular distance to be symmetrical arranged.
The present invention extends in the wall body direction of described four minutes ring upper edge annular distances and is useful on the boss that plays the role of positioning with locating that collar cooperates.
The present invention is because after adopting said structure, one of advantage that has: open and close that container becomes fast, facility, save time, laborsaving, save cost again, as long as with 3.0 type filters is example, and more renew cartridge only needs people's operation, changes a filter core 15 minutes, the O RunddichtringO does not need to change yet, like this, approximately need 5000 of replacings to calculate, just can save about 700～1,100 ten thousand yuan of renewal cost so that the whole nation is annual; Two of advantage: closure mechanism has the self-locking structure, it is to utilize the pressure of self rock gas in the container with sealing cover jack-up, seal by O type circle between airtight cover and hub, four fens rings reach the requirement of self-locking sealing with protecting cover jack-up, and are not only simple in structure, easy to use, and good seal performance, can effectively prevent the gas leakage of container, the incidence rate of reduction accident greatly.
