Description
Technical field
The utility model relates to a kind of strainer, specifically refers to fast-open type natural gas filter.
Background technology
The normal fast-open type natural gas filter that uses in the transmission & distribution of city gas.Enter the Sweet natural gas of gas distribution station, because carry at a distance or other reason, always with a small amount of micron order or submicron order impurity, (Sweet natural gas produces erosion to pipeline inwall, upper level gas gathering station, purification plant or gas distribution station carry out the residual impurity after separation, dedusting, purification to Sweet natural gas) the normal smooth running of impact station internal pressure-regulating device, measuring apparatus, so all must come gas to carry out purifying and dedusting to upper level at last one station to user's air feed, to guarantee tight gas supply.
At present, the strainer on market, for guaranteeing that the precision equipments such as pressure regulation, metering stablize air feed, the workman that needs repairing need open cleaning filter filter core continually, and workload is very heavy.In addition, be subject to the restriction of sealing property and structural strength, oneself is not suitable for blind flange bolt type strainer in the strainer that pressure is higher, barrel dliameter is larger.
Utility model content
The utility model provides fast-open type natural gas filter, solves the problem of frequently opening when natural gas filter cleans and causing working strength to increase, and reaches the object of opening fast or closing strainer.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises cylindrical shell and upper cover, described cylindrical shell is provided with inlet mouth and air outlet, cylinder body bottom is provided with wash water valve, and the inside of cylindrical shell is provided with filter core, and described filter core is communicated with inlet mouth, air outlet is communicated with inner barrel, described cylindrical shell is connected with upper cover by lifting eye bolt, and upper tops is connected with handwheel by screw rod, and upper tops coordinates with screw flight, also comprise the pivot arm being arranged on cylindrical shell, the end of pivot arm is connected with screw flight.The top of cylindrical shell is connected and fixed by welding and outside erecting frame, the bottom of cylindrical shell is provided with wash water valve, can not only play the effect of emptying pressure release, the solid particulate isolating or liquid impurity can also be got rid of to the convenient clean and maintenance to filter core in filter core; The dust of the larger particles in the Sweet natural gas being passed through by inlet mouth or impurity are done inertial motion with Sweet natural gas flow at high speed, and when air-flow runs into obstacle and detours, dust is online because inertia departs from air flow line and bumps against the filter wire of strainer, and barred is in net; After the filtration of one-time surface formula, Sweet natural gas continues by a plurality of filter pore on bed filtration silk screen, filter pore has many bending channels, the number of plies is more, be that filtration area is larger, the dust in Sweet natural gas constantly bumps with filtering silk screen, and very little granule dust is also done random pedesis, the kinetic energy of dust constantly reduces, and is stuck in filters in silk screen until can not move; Finally by the Sweet natural gas filtering, passing through air outlet discharge filter, the impurity in filter core is got rid of by wash water valve, makes its running stable.
After long-time use, need to clean strainer, rotating suspension ring bolt separates upper cover and cylindrical shell, regulate the handwheel of upper tops simultaneously, by upper cover ascending one segment distance, then open by upper cover and cylindrical shell dislocation by rotating pivot arm, then take out fast filter core and clean; Be connected and compare with traditional flange bolt, the time that strainer is uncapped shortens greatly, has reduced workman's labour intensity, has improved working efficiency.
Further, also comprise the end socket arranging between cylindrical shell and upper cover, end socket is provided with O RunddichtringO.Because upper cover is that bolt is connected with handwheel, be in use easy to the pressure release of leaking gas, so end socket and O RunddichtringO are installed between cylindrical shell and upper cover to ensure pressure-stabilisation in cylindrical shell, air tight.
Further, described filter core top is scarp, scarp and horizontal plane angle at 45 °, and described inlet mouth is over against scarp, and filter core is communicated with inner barrel by scarp.Filter core adopts the design of upper end open, lower end closure, bottom at cylindrical shell is provided with scarp, scarp is over against inlet mouth, Sweet natural gas directly enters filter core from inlet mouth, filtration silk screen by multilayer carries out filtration treatment, thereby increased the contact area of Sweet natural gas and filter core, be convenient to Sweet natural gas and enter into fast filter core and filter.
Further, the bottom of described cylindrical shell is semisphere, and described wash water valve is arranged on the lower-most point of the bottom of described housing.Usually cylinder body bottom is made as plane, easily causes the impurity filtering to be piled up in convenient placement, is difficult to get rid of from wash water valve; The cylinder body bottom of semisphere design can make impurity from wash water valve, flow out fast under the effect of self gravitation, the cleaning of convenient filter.
Further, also comprise the differential pressure gauge that is arranged on drum surface, the two ends of described differential pressure gauge are connected with inlet mouth, air outlet respectively.Usually, strainer can regularly clean, but because uncertainty causes filter core net damaged, does not carry out in time dress watch and can cause the filter effect of Sweet natural gas greatly to reduce; Differential pressure gauge can be pointed out the change value of pressure of strainer rear and front end in real time, for the strainer suitable clean period of statistics provides scientific basis, plays cost-saving, the time, and the effect maintaining easily, can save energy and reduce the cost effectively.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises cylindrical shell and upper cover, described cylindrical shell is provided with inlet mouth and air outlet, cylinder body bottom is provided with wash water valve, and the inside of cylindrical shell is provided with filter core, and described filter core is communicated with inlet mouth, air outlet is communicated with inner barrel, described cylindrical shell is connected with upper cover by lifting eye bolt, and upper tops is connected with handwheel by screw rod, and upper tops coordinates with screw flight, also comprise the pivot arm being arranged on cylindrical shell, the end of pivot arm is connected with screw flight; After long-time use, need to clean strainer, rotating suspension ring bolt separates upper cover and cylindrical shell, regulate the handwheel of upper tops simultaneously, by upper cover ascending one segment distance, then open by upper cover and cylindrical shell dislocation by rotating pivot arm, then take out fast filter core and clean; Be connected and compare with traditional flange bolt, the time that strainer is uncapped shortens greatly, has reduced workman's labour intensity, has improved working efficiency.
