The utility model also can be done following improvement: a ring packing panel is set on described runner plate; The plate face of the two is fitted mutually; The plate body side of this ring packing panel joins with the top edge of the logistics import that is connected handle, and the plate body side of said blind plate body joins with the lower edge of the logistics import that is connected handle.
A mode of execution as the utility model: described conduit is that the body of connecting end diminishes gradually from body to end and forms the special-shaped conduit of flat interface, and the logistics outlet of said connection handle is flat, with adaptive connection of flat interface of conduit.Along with the blind plate pressure rating raises, thickness increases, and said conduit also can adopt circular pipe.
The described blind plate body of the utility model, runner plate, connection handle and conduit all adopt the stainless steel manufacturing.And described blind plate body and runner plate are integrated.
Said blind plate body is complete circular plate, and the appearance profile edge of said runner plate and the appearance profile edge of blind plate body flush.
The middle part through hole of said ring packing panel is identical with the aperture of the middle part through hole of runner plate.
Compared with prior art, the utlity model has following beneficial effect:
(1) runner plate of the utility model has in flow-guiding mouth and the connection handle and has logistics corridor; Logistics is flow in the recovery channel through the logistics corridor that connects handle by the flow-guiding mouth outflow of runner plate; Making logistics be able to concentrate reclaims; Solve the discharging recovery problem of processing medium in the pipeline effective and reasonablely, and improved the apparatus system regional environment to greatest extent.
(2) the utility model is provided with conduit; Can connect at the outlet end of conduit block valve, sampling valve, pressure gauge etc. are set; Connect the temporary pipeline drainage then to enclosed recovery system, the controlling plumbing fixtures processing medium flow direction of blind plate endways realizes operability effectively; Thereby realize pipeline sweep only, put have leisure, no dead angle, pollution-free, thereby avoid the contamination hazard of processing medium when the opening pad discharges.
(3) the utility model is provided with the runner that supplies logistics to flow out, and the effective flow area of runner is enough, and is unimpeded reliable, uses the standard pad in the time of installation and need not use the opening pad.
(4) the utility model constructing operation is with to pull and push common blind plate same; Need not to increase extra construction work amount; And simple and practical, installation and maintenance are easy; And improve the apparatus system regional environment to greatest extent, and satisfy safety, health and environment (HSE) field management requirement, have value for applications preferably.
