Abstract
The utility model relates to a rigid ball valve which is composed of a valve body, a valve core, a valve rod, etc., wherein, the upper end of the valve core is provided with a circular hole, the lateral position of the upper part of the valve core is drilled with a horizontal cone hole capable of being communicated with the circular hole, and meanwhile, the valve rod is also correspondingly provided with a horizontal cone hole which is communicated with the circular hole; the bottom end of the valve rod is positioned in the circular hole of the valve core, the cone hole on the valve rod is correspondingly communicated with the cone hole of the valve core, a conical pin is inwards knocked in the taper holes, and then the valve core is tightly connected together with the valve rod. Compared with the prior art, the product of the utility model has the advantages of reliable performance, long service life, etc.
Description
The utility model relates to a kind of valving that is used to control conveyance conduit inner fluid break-make, and its product is suitable for connecting dress in all kinds of delivery lines (water delivery, gas transmission, pipeline road) in fields such as oil, chemical industry, rubber, printing and dyeing, boiler, papermaking, building heating ventilation.
Existing ball valve product ubiquity the manufacture cost height, defectives such as precision is poor, the life-span is short, the easy axial float of valve rod, particularly because valve rod and spool are taked the free gap connecting mode, spool frequently is subjected to the bump and the friction of valve rod, be easy to mechanical fatigue, and then be damaged so that scrap (the reference technique file: Ministry of Machine-Building Industry publishes " valve products sample "-85.10 front pages).
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of reliable performance, lower, the durable Rigid ball valve of cost are provided.
The purpose of this utility model can be achieved by following technical solution: the Rigid ball valve that is provided is by the valve body with pipe passage, be located at the spool in the valve body and the valve rod of valve core rotation is formed, be connected with operating handle on the valve rod, have a circular hole in the upper end of spool, be drilled with a level that can feed this circular hole to taper hole at the lateral position place on spool top, simultaneously also have a level that communicates with it to taper hole in the corresponding position of valve rod, put the valve rod bottom to the spool circular hole and the taper hole on it is communicated with the contraposition of spool taper hole, inwardly knock in behind one piece of taper pin together spool and valve rod close-coupled along taper hole.
Compared with prior art, the utility model is owing to become rigid body with spool and valve rod close-coupled together, not only overcome the problem of frequent friction and bump between spool that old-fashioned ball valve product exists and valve rod, also avoid the phenomenon of the easy axial float of valve rod in the original structure, so just greatly improved the working life of product.Experimental result shows: by the Rigid ball valve that technique scheme is made, improve 10～15 times or more than old-fashioned ball valve its working life, and manufacturing process, frock, mould etc. also need not big change, is suitable for the large quantities of manufacturings of professional ball valve manufactory; In addition, scheme described in the utility model also is fit to simultaneously to written-off ball valve place under repair, ball valve more original old-fashioned infrastructure product in its working life after repairing also can improve more than 10 times, therefore, the utility model technology has higher utility, and the application of its product will bring considerable economic to valve manufacturing firm and numerous industrial and mineral applying units undoubtedly.
Below with reference to accompanying drawing behind the literary composition the utility model content is described further.This accompanying drawing is the structural representation of a specific embodiment of the utility model.
With reference to accompanying drawing, this Rigid ball valve is made up of members such as valve body 5, spool 3, valve rod 1 and operating handles 8.During making, open a circular hole, join to outwardly along level in this circular hole side-walls again and bore a taper circular hole and this taper hole of hinge circle in spool 3 upper ends; Cylindrical structural is processed at valve rod 1 two ends and joins level that communicates with this taper hole of brill to taper hole corresponding to spool taper hole position in valve rod 1 bottom, during the product assembling, insert valve rod 1 in spool 3 circular holes and make the two taper hole contraposition, taper pin 2 knocked in spool 3 and valve rod 1 close-coupled are in the same place, this taper pin can take out in easily by taper hole with fitter's tool " pin puller " when needs are dismantled.In the structure, label 4 is provided with circle formula spring 6 for being located at the seal ring 4 of 3 mouthfuls of outer both sides of spool at seal ring 4 external pressures shown in the accompanying drawing, can make seal ring 4 and spool 3 paste tightlyer like this, improves the sealability of product.In addition, connect by one piece of screw 7 between valve rod 1 top and the operating handle 8.
Claims (3)
