Abstract
The utility model relates to a filter and discloses a quick-opening brainpan fuel gas filter in order to solve the starting and closing arts of brainpans of large-scale fuel gas filters. The utility model includes a filter body and a filter cover, and is characterized in that the head of the filter body is arranged with a high neck, an O-shaped obturating ring is arranged in an upper plane trough of the high neck, a close cover is arranged above the high neck, the shoulder blade bevel of the high neck and the shoulder blade bevel of the close cover are locked in a groove of a lathe dog and connect two lathe dogs and a positioning bracket together which are adjacent by two-way bolts, when starting or closing the filter, the two lathe dogs can be opened or furled at the same time by screwing with threaded studs, and the close cover can be fastened and loosened. The utility model adopts a high neck and lathe dog type open and close structure, thus having the advantages of fast opening and closing speed, good sealability, easy installation and maintenance, and time and labour saving.
Description
Technical field
The utility model relates to filter, belongs to large-scale combustion gas filter especially.
Background technology
Along with the combustion gas conveying of big flow, high pressure and the development of regulator, gas industry is more and more higher to the requirement of various types of filtration device, and traditional filter head adopts the flange pattern, be connected with flange by bolt with gasket seal with blind flange, play sealing function, but concerning big specification, high pressure filter, adopt the flange form head to need bigger and a fairly large number of bolt, the mounting or dismounting difficulty wastes time and energy when installing and keep in repair.
Summary of the invention
For solving the start and stop technology of large-scale gas filter head lid, the purpose of this utility model provides fast-open type skull gas filter, and it can fast and like a cork open and close strainer cover, is convenient to the installation and the maintenance of internals.
The utility model is to realize by following technical scheme, it comprises filter body, lid, its structural feature is that the head of filter body is provided with hub, the circumference symmetry two sides of filter body cylindrical respectively is provided with a locating support, the upper end of hub is provided with inclined-plane omoplate cylindrical, be provided with " O " RunddichtringO in the last planar circumferential groove of hub, the hub top is provided with closed cover, the lower end of closed cover is provided with inclined-plane omoplate cylindrical, the hub inclined-plane omoplate and the closed cover inclined-plane omoplate that are positioned at two locating support both sides are provided with clip outward, and by bolt two adjacent clips are connected together, in locating support hole and two adjacent clip screwed holes, be provided with right-and-left threaded two-way bolt.
Be provided with a braking bolt in the screw of above-mentioned locating support upper end.
Above-mentioned hub upper end cylindrical is provided with a safety cock.
The utility model adopts filter body head hub and clamping hoop type opening and closing structure, forms end face seal by " O " RunddichtringO between hub and the closed cover, relies on clip that closed cover is tightened up.Good seal performance, the keying speed of lid is fast, is easy to install and maintenance, and is time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure schematic top plan view.
The specific embodiment
The utility model is described in further detail below with reference to the embodiment of accompanying drawing.
Among Fig. 1 and Fig. 2, the hub 1 integrally welded with the filter body head, locating support 6 are fixed by welding on the filter body circumference symmetry two sides.Clip 2 is contained in the both sides of locating support 6, and two adjacent clips are linked to each other by bolt 9, and hub inclined-plane omoplate and closed cover 4 inclined-plane omoplates are stuck in the groove of clip 2." O " RunddichtringO 3 is used for end face seal, and two-way bolt 8 is positive and negative two to screw thread, can open or draw in two adjacent clips simultaneously.Safety cock 7 is welded in the aperture of hub 1 circumference, and its inside is spherical hermetically-sealed construction, plays the security alarm effect.Braking bolt 5 plays locking and protective effect.When closed cover 4 was closed, two-way bolt 8 was tightened, and two adjacent clips 2 draw in opposite directions and to radially moving, the hub 1 and the omoplate inclined-plane of closed cover 4 clamped under two-way bolt effect.The radial seal effect is played in the extrusion of " O " RunddichtringO.At this moment tighten braking bolt 5, prevent that right-and-left threaded two-way bolt 8 from becoming flexible, and improved reliability.When closed cover 4 is opened, back out braking bolt 5, unscrew two-way bolt 8 gradually, slowly open closed cover 4.If rotate safety cock 7 under the band pressure state, the aperture in the safety cock can send gas and call and report to the police.
