Abstract
The utility model discloses a floating-type sealing mouse cage valve which comprises a valve body, a valve deck, a supporting frame, a sealing base in the valve body, a balance cylinder in the valve body, a valve element in an inner bore of the balance cylinder, a lower valve rod connected with the valve element, and an upper valve rod connected with the upper end of the lower valve rod. A sleeve is arranged in the valve body and provided with a flow pass hole. A valve positioner is arranged on the supporting frame. The outer contour of the lower end of the valve element is provided with a connecting piece in the shape of a circular ring. A clamping sheet is arranged in the lower portion of the connecting piece, and the diameter of the clamping sheet is smaller than that of the circular ring of the connecting piece. A sealing sheet is arranged in the connecting piece and above the clamping sheet. The outer diameter of the clamping sheet presses the sealing sheet through a spigot.

According to the floating-type sealing mouse cage valve, a traditional stationary-type sealing sheet of a valve is designed to be a floating-type sealing sheet, and when the sealing sheet is not smooth in contact due to valve machining errors and other factors, the floating-type sealing sheet can be adjusted automatically to achieve a better sealing effect.
Description
Technical field
The utility model relates to a kind of floating type sealing mouse cage valve.
Background technique
Along with the maximization of pressure-swing absorption apparatus, medium differential pressure, flow velocity sharply increase, and cause going from bad to worse of valve applying working condition environment.Along with the increase of medium differential pressure, flow velocity, conventional valves has not been satisfied the demand at aspects such as diaphragm seal protection against erosion, sealing reliabilities, and this just need improve conventional valves, redesign.
Show through research experiment, the problem of washing away of diaphragm seal mainly concentrates on the moment of valve open, the damage that velocity of medium is too big, rate-of flow big or small uncontrollable (because contain particle such as sorbent in the medium, particle is more many also more big to the diaphragm seal infringement) causes diaphragm seal.
The model utility content
The purpose of this utility model is at above-mentioned situation, and the floating type sealing mouse cage valve that a kind of floating seal sheet can self-adjusting better tightness is provided.
The purpose of this utility model realizes by following technical proposals:
A kind of floating type sealing mouse cage valve, comprise valve body, be connected the valve gap on the valve body, the supporting frame that the lower end links to each other with valve gap, the sealing seat of valve inner, the compensating cylinder of valve inner, spool in the endoporus of compensating cylinder, the lower valve rod that links to each other with spool, the upper valve rod that links to each other with the lower valve rod upper end, described valve inner is provided with sleeve, sleeve is under the compensating cylinder, on the sealing seat, the sleeve upper end is balanced cylinder and pushes down, sealing seat is pushed down in the sleeve lower end, sleeve is provided with the runner hole, supporting frame is provided with valve positioner, the valve positioner driving lever drives valve rod, spool lower end external frame is provided with the link of ring, the below, inside of link is provided with diameter less than the holding sheet of the ring of link, link inside, the holding sheet top is provided with diaphragm seal, the external diameter of holding sheet is pushed down diaphragm seal by seam, and the internal diameter of link is pushed down diaphragm seal by seam, leaves the gap between diaphragm seal and link and the holding sheet.
As optimal way, described gap is 0.3-0.5mm.
As optimal way, link is by being threaded on the external frame of spool lower end.
As optimal way, holding sheet links to each other with the spool lower end surface by hexagon socket cap head screw.
As optimal way, the upper end of sleeve is connected by seam with compensating cylinder, and the lower end of sleeve is connected by seam with sealing seat.
As optimal way, be provided with the Kazakhstan between upper valve rod and the lower valve rod and not encircle, to breathe out and not encircle by lower valve rod and the upper valve rod of being threaded, two lobes are breathed out not and are linked to each other with hexagon socket cap head screw between the ring.
As optimal way, after piston inner hole is passed in the upper valve rod upper end, fixedly connected with piston by the hexagon slotted nut.
As optimal way, the driving lever of described valve positioner connects breathes out not ring.
As optimal way, valve positioner is provided with feedback rod, and feedback rod is connected with driving lever.
Diaphragm seal is designed to the adjustment structure of relying on oneself of floating, because valve parts adds and has concentricity, planeness equal error man-hour, cause that valve when assembling diaphragm seal surface and sealing seat are surperficial to be contacted out-of-flatness (the conventional valves diaphragm seal is fixed and has pushed down, again because the High Pressure Difference valve all has compensating cylinder, spool to-and-fro motion in compensating cylinder again, for guaranteeing the leveling style of valve core movement, so gap between the two is very little, spool can not swing in compensating cylinder), if diaphragm seal contacts out-of-flatness with sealing seat, will cause valves leakage.And the floating seal chip architecture can be impelled when having out-of-flatness between diaphragm seal and the sealing seat, by self float to adjust make contact between diaphragm seal and the sealing seat good, thereby reach good sealing effect, and then the reliability of increase valve.
This valve has increased sleeve design, because the runner of sleeve self can fine reduction velocity of medium, reduces the medium noise result thereby reach.After increasing sleeve; in the preliminary stage of valve opening; can reduce the rate-of flow by the valve two ends; because rate-of flow, flow velocity by the valve two ends are all less; this has just well protected diaphragm seal; prevent excessively washing away of diaphragm seal, thereby further improved the abrasion resistance energy of valve.
The beneficial effects of the utility model: compare with conventional seals, between the diaphragm seal of floating type sealing mouse cage valve and link and the holding sheet certain clearance arranged, can make about the diaphragm seal, about float; Aspect the valve seal reliability, the utility model is designed to floating type diaphragm seal with the fixed diaphragm seal of conventional valves, when causing diaphragm seal contact out-of-flatness because of reasons such as valve machining errors, can reach better sealing effect by automatic adjustment of floating seal sheet.
