Description
Technical field
The utility model relates to a kind of gate valve, specifically refers to a kind of difunctional bellows gate valve.
Background technique
Gate valve is the main valve working the mobilization cutting off transported medium on pipeline, its structure comprises valve body, valve rod, valve gap, flashboard etc., flashboard moves along the Vertical direction of path center line and realizes the function of opening and closing, existing gate valve can be divided into two kinds by the screw position by valve rod, one is hidden-rod gate valve, and another kind is rising stem gate valve.Porose in the middle of the flashboard of hidden-rod gate valve, flashboard body is thick, and the flashboard of rising stem gate valve is solid, middle atresia, flashboard body is thin, and thus supporting with it valve body is also different, flashboard and the valve body of two kinds of gate valves do not have interchangeability, there is production management complexity, the shortcoming that cost is high.
A kind of Multi-purpose Corrugated Pipe Discharge Gate of the applicant's earlier application, is 201120245571.3 see China Patent No., solves the problems referred to above preferably for this reason.
But, existing gate valve limits due to its structure characteristic, only play the function of Trimmed sums conducting medium, function is comparatively single, especially some are contained to the medium of solid impurity, its impurity when medium is at valve open together with mixed flow and mistake, the pipeline of gate valve rear end and equipment thereof are often blocked because of the accumulation of solid impurity.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides one to have to filter and block medium double action and versatility is good, and rising stem type and the dual-purpose difunctional bellows gate valve of one of blind rod type.
For achieving the above object, the technical solution of the utility model comprises valve body, flashboard, valve gap, valve rod, valve stem casing, with valve rod lift drive mechanism, runner is provided with in described valve body, described runner is at the both-side opening of valve body, and described valve body is provided with valve seat relative on runner, described flashboard lifting is arranged in valve seat actively, and the upper end of this flashboard and valve rod are fixedly linked, described valve rod is divided into upper valve rod and lower valve rod, upper valve rod and valve gap form radial movable, axial restraint connects and coordinates, the upper end of lower valve rod is connected with upper valve rod screw-driven, the lower end of lower valve rod is fixedly connected with flashboard, described upper valve rod is arranged with bellows, one end of bellows and valve gap fixed seal connection on this, on this, the other end of bellows and upper eyelet are welded and fixed, and the inwall fixed seal connection of eyelet and valve stem casing on this, described lower valve rod is arranged with lower bellows, one end of this lower bellows and lower valve rod fixed seal connection, the other end and the lower eyelet of this lower bellows are welded and fixed, and the inwall fixed seal connection of this lower eyelet and valve stem casing, described valve body is provided with valve body cavity of resorption relative to the below of valve seat, described flashboard includes and is positioned at top and the upper flashboard coordinated with valve base sealing, one be longitudinally arranged at the lower filter plate below upper flashboard and be positioned at lower filter plate longitudinally below and with sealing block at the bottom of the flashboard of valve base sealing adaptation, the diameter of this lower filter plate is consistent with valve seat hole size, and this lower filter plate is provided with multiple filtering hole.
Further setting is that described valve rod lift drive mechanism includes the handwheel be linked with valve rod.
The utility model has the advantages that by valve rod is combined by the upper valve rod be threaded and lower valve rod, the sliding channel of the direction switch making hidden-rod gate valve original is by transferring in the screw-driven cooperation of upper valve rod and lower valve rod in flashboard, the flashboard of rising stem (RS.) and inside screw non-rising stem type gate valve and valve body are united, realize interchangeability, thus the utility model has the advantage that product specification is unified, cost of production is low, production management simplifies.The utility model adopts upper bellows and lower bellows to seal, good airproof performance, and by arranging upper eyelet and lower eyelet, welding operation is convenient, and welding quality is good.
In addition, the utility model is when flashboard moving and make lower filter plate be arranged in the valve flowing channel of valve seat, and the filtering hole on lower filter plate, serves the effect of impurity screening.When valve is in closed condition, the same with the function of plate valve, play seal action.Thus valve has dual functions, namely can filter, can medium be blocked again.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 the utility model embodiment structural representation.
