Abstract
The utility model discloses a multi-purpose bellows sluice valve, which comprises a valve body, a flashboard, a valve cover, a valve rod, a valve rod sleeve and a valve rod operation mechanism. The valve cover is fixedly connected with the valve body. The valve rod is movably connected with the valve cover, and the valve rod is in transmission connection with the flashboard. The multi-purpose bellows sluice valve is characterized in that the valve rod is divided into an upper valve rod and a lower valve rod. An upper bellows is arranged on the upper valve rod in sleeving mode, one end of the upper bellows is fixedly connected with the valve cover in sealing mode, the other end of the upper bellows is fixed with an upper metal ring in welding mode, and the upper metal ring is fixedly connected with the inner wall of the valve rod sleeve in sealing mode. A lower bellows is arranged on the lower valve rod in sleeving mode, one end of the lower bellows is fixedly connected with the lower valve rod in sealing mode, the other end of the lower bellows is fixed with a lower metal ring in welding mode, and the lower metal ring is fixedly connected with the inner wall of the valve rod sleeve in sealing mode. The multi-purpose bellows sluice valve has the advantages of having good generality and two purposes of a rising rod and a nonrising rod.
Description
Technical field
The utility model relates to a kind of gate valve, specifically is meant a kind of Multi-purpose Corrugated Pipe Discharge Gate.
Background technique
Gate valve is the main valve that cuts off the mobilization that is transferred medium that rises on pipeline; Its structure comprises valve body, valve rod, valve gap, flashboard etc.; Flashboard moves and the function that realizes opening and closing along the Vertical direction of path center line; Existing gate valve can be divided into two kinds by the screw position by valve rod, and a kind of is the blind rod type gate valve, and another kind is a rising stem gate valve.Porose in the middle of the flashboard of blind rod type gate valve, the flashboard body is thick, and the flashboard of rising stem gate valve is solid; Middle atresia, the flashboard body is thin, thereby the valve body supporting with it also has nothing in common with each other; The flashboard and the valve body of two kinds of gate valves do not have interchangeability, exist production management complicated, the shortcoming that cost is high.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and provides a kind of versatility good, and rising stem (RS.) formula and the dual-purpose a kind of Multi-purpose Corrugated Pipe Discharge Gate of blind rod type.
For realizing above-mentioned purpose, the technological scheme of the utility model is to comprise valve body, flashboard, valve gap, valve rod, valve stem casing and valve rod operating device, and valve gap is fixedly connected with valve body; Valve rod and valve gap flexibly connect, and this valve rod and flashboard be in transmission connection, and described valve rod is divided into upper valve rod and lower valve rod; Upper valve rod is radially movable with the valve gap formation, axial restraint is connected cooperation, and the upper end of lower valve rod and upper valve rod screw thread are in transmission connection, and the lower end of lower valve rod is fixedly connected with flashboard; Be arranged with bellows on the described upper valve rod; Should go up an end and the valve gap fixed seal connection of bellows, welding of the other end of bellows and last eyelet is fixed on this, and should go up the inwall fixed seal connection of eyelet and valve stem casing; Be arranged with down bellows on the described lower valve rod; One end of this time bellows and lower valve rod fixed seal connection, the other end of this time bellows is fixing with following eyelet welding, and the inwall fixed seal connection of this time eyelet and valve stem casing.
Further being provided with is that described valve rod operating device is a handwheel.
The utility model has the advantages that through valve rod is made up by upper valve rod that is threaded and lower valve rod; The sliding channel that makes the original direction switch of blind rod type gate valve is by in flashboard and during the screw thread transmission of transferring to upper valve rod and lower valve rod cooperates; The flashboard and the valve body of rising stem (RS.) and inside screw non-rising stem type gate valve are united; Realize interchangeability, thereby the utlity model has the advantage that product specification is unified, cost of production is low, production management is simplified.
In addition, the utility model employing is gone up bellows and is sealed with following bellows, good airproof performance, and through eyelet and following eyelet are set, welding operation is convenient, and welding quality is good.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation.
