Abstract
The utility model discloses a guide regulating valve of a high-pressure multistage depressurization sleeve. The guide regulating valve comprises a valve body, a valve seat, a balancing seat, a valve rod and a valve cap, wherein the valve cap is fixed on the valve body; the valve rod is arranged in the valve cap in a penetrating manner; the valve seat is arranged in the valve body and sheathed at the tail end of the valve rod; the balancing seat is sheathed on the valve rod; a maze lamination is arranged between the balancing seat and the valve seat; a sleeve is also arranged between the balancing seat and the valve seat, sheathed on the valve rod and arranged in the maze lamination; a sleeve cushion is arranged between the sleeve and the valve seat; and as the sleeve is added between the balancing seat and the valve seat, sheathed on the valve rod and arranged in the maze lamination, the sleeve can effectively protect the valve rod and prevents the valve rod from being impacted by flow media, thus improving control precision of the product and further improving the whole sealing of the valve body.
Description
Technical field
The utility model relates to a kind of high-pressure multi-stage step-down cage guiding modulating valve, is particularly useful in High Pressure Difference industrial fluids, gas, the gas-liquid mixed phase system, plays and regulates and the shutoff effect, belongs to automation field.
Background technique
At present, in High Pressure Difference industrial fluids, gas, gas-liquid mixed phase system, valve is primary element of realizing whole system automation control, and its effect is that mainly pressure regulates and control flow rate.Because high-pressure multi-stage reduction regulation valve is to carry out under the environment of high pressure, the speed of its flowing medium is very fast, and too fast speed can be brought certain shock-effect, and traditional high-pressure multi-stage reduction regulation valve, corresponding fixing device is not set between its valve rod and the valve seat, is used for shockproofly and prevent of the impact of too fast flowing medium, depart from so easily produce between valve rod and the valve seat to valve rod, thereby influence the control accuracy of valve rod, and then influence the overall tightness of high-pressure multi-stage reduction regulation valve.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of and has been with shockproof and protecting against shock, and the valve rod control accuracy is higher, valve seal high-pressure multi-stage step-down preferably cage guiding modulating valve.
For achieving the above object, the utility model provides a kind of high-pressure multi-stage step-down cage guiding modulating valve, comprises valve body, valve seat, balance seat, valve rod, valve gap, and valve gap is fixed on the valve body, valve rod is located in the valve gap, valve seat is located in the valve body, and is socketed on valve stem end, and the balance cover for seat is connected on the valve rod, be provided with the labyrinth lamination between balance seat and the valve seat, also be provided with sleeve between balance seat and the valve seat, described jacket casing is connected on the valve rod, and is located in the lamination of labyrinth.
The beneficial effects of the utility model are: owing to have additional sleeve between balance seat and valve seat; described jacket casing is connected on the valve rod; and be located in the lamination of labyrinth; so sleeve can effectively be protected valve rod; make valve rod not be subjected to the impact of flowing medium; improve the control accuracy of valve rod, and then improved the overall tightness of valve body.
The utility model can further be set to be provided with between described sleeve and the valve seat sleeve pad.
The utility model also can further be set to be provided with black box between described valve rod and the valve gap.
The utility model also can further be set to described black box and comprise Packing seat, filler, filler spacer ring, follower, hold-down grid, and is equipped with Packing seat, filler, filler spacer ring, filler, follower, hold-down grid successively by assemble sequence from the bottom up.
