Description
Technical field
The utility model relates to a kind of stopcock technical field, particularly a kind of novel three-way stopcock.
Background technique
Plug valve is the rotary valve of closure member or plunger shape, by 90-degree rotation, the passway on valve plug is communicated with the passway on valve body or separates, and realizes a kind of valve opened or close.The shape of the valve plug of stopcock can become cylindrical or conical.In cylindrical valve plug, passage is generally orthogonal; And in cone-shaped valve plug, passage in echelon.What these shapes made stopcock becomes light and handy in particular to a kind of structure, but also creates certain loss simultaneously.Stopcock is most suitable for as cut-out and connects medium and shunting is suitable for, but according to the character be suitable for and the abrasion-resistance of sealing surface, sometimes also can be used for throttling.Owing to moving with wiping action between stopcock sealing surface, and the contact with flowing medium can be prevented completely when standard-sized sheet, therefore it also can be used for the medium with suspended particulate usually.During another key property of stopcock, it is easy to adapt to multi-channel structure, so that a valve can obtain two, three, even four different runners.The design of pipe-line system can be simplified like this, reduce some connection fittings needed in valve consumption and equipment.The working life of existing threeway plug valve is low, poor sealing performance, needs to change frequently, extremely bothers.
Model utility content
Problem to be solved in the utility model is to provide a kind of novel three-way stopcock, solves existing threeway plug valve low for working life, the problem of poor sealing performance, avoids producing the frequent phenomenon changed, the working efficiency of improving product.
For overcoming the above problems the scheme that the utility model adopts:
A kind of novel three-way stopcock, comprise handwheel, valve rod and valve body, described valve body both sides are provided with import, first outlet exports with second, the first described outlet exports with the center line of valve body as symmetry axis is arranged axisymmetricly with second, described import and the first exit normal are arranged, described valve body top is provided with gland, the first packing layer is provided with between described gland and valve body, packing layer is provided with successively in the first described packing layer, pad and lower packing layer, described valve rod one end is inserted in valve body, the other end is provided with screw thread, described valve rod is vertical with valve body to be arranged, the second packing layer is provided with between described valve body and valve rod, the second described packing layer is fluoroplastics layer, the second described packing layer is vertical with the first packing layer to be arranged, described handwheel central position is provided with screw, described handwheel is achieved a fixed connection by nut and valve rod, described handwheel surface is provided with region of carving characters.
Above-mentioned a kind of novel three-way stopcock, wherein, described pad, valve rod and valve body are made up of brass.
Above-mentioned a kind of novel three-way stopcock, wherein, described fluoroplastics layer is tetrafluoro polyethylene.
The beneficial effect of this programme:
A kind of novel three-way stopcock that the utility model provides, structure is simple, reasonable in design, valve body both sides are provided with import, the first outlet exports with second, first outlet exports with the center line of valve body as symmetry axis is arranged axisymmetricly with second, import and the first exit normal are arranged, and are convenient to the circulation of current, improve unobstructed performance; The first packing layer is provided with between gland and valve body, the second packing layer is provided with between valve body and valve rod, second packing layer is vertical with the first packing layer to be arranged, packing layer, pad and lower packing layer is provided with successively in first packing layer, by multi-layer sealed mode, the sealability of product is strengthened, improve the working efficiency using producer, avoid occurring changing phenomenon frequently, pad, valve rod and valve body are made up of brass simultaneously, improve the quality of product, avoid the phenomenon producing blocking after getting rusty, extend the working life of product; Region of carving characters is set on handwheel surface, is convenient to word, pattern, anti-counterfeiting mark and the mark on date, guarantees both quality and quantity.
