Description
The utility model relates to a kind of integral (type) flange ball valve.
Valve is all multidisciplinary a kind of engineering goods that all need of national economy.Ball valve then is a kind of novel block valve, and its open-shut device is to do rotation motion by valve rod, handle round the vertical center line of valve body by the ball core.With cast iron, cast steel or stainless steel is the Flange Ball Valves that raw material are made, and main body is divided into valve body and valve gap two major parts, and structure length is big, and processing technology is numerous and diverse, and it is many to consume raw material; Middle flange flexibly connects, and influences the ball valve sealing performance; Stuffing box be configured to roll blue gland type traditional design, poor sealing performance, bite and material consumption are higher; Valve rod axial seal uses V-shaped seal ring to increase the material consumption; Switch is unidirectional spacing, and the keying control range is narrow.
The purpose of the utility model is to avoid the deficiency of above-mentioned prior art, provides a kind of in light weight, and corrosion resistance is strong, saves material, the integral (type) flange ball valve of good sealing effect, novel structure.Hot galvanizing integral (type) flange ball valve is applicable to the supporting use of Coating Steel Pipe.
Task of the present utility model realizes by following technical proposals.
Basic structure of the present utility model comprises flange valve body, inner flange nut, bedding and padding case and ball core.The whole manufacturing of flange valve body is equipped with the fixedly inner flange nut of ball core again.Ball core, seal ring are loaded on body cavity.Bedding and padding case and valve body are formed eccentric three-port structure.Be provided with down-mounting type valve stem seal self-tightening mechanism at bedding and padding case place, this mechanism mainly comprises two-way dovetail seal ring, peach shape trim ring, stage clip, two-way link stopper and valve rod fastening nut.This mechanism has Transverse plane sealing and the dual performance of axial seal.Transverse plane sealing is by stage clip tension force, nut screwing clamping power and separate the total effect of selfsealings power that matter pressure produces valve rod by fluid, and its axial seal mainly is pressured circle and nut screwing clamping power and realize.

Fig. 9 is that peach shape trim ring, stage clip and two-way dovetail seal ring are loaded on first dress on the valve rod and the schematic representation after the compacting.
Below, in conjunction with the accompanying drawings the utility model is described in detail.
Valve appearance of the present utility model is two end flange, the wounded in the battle key stiffening rib of the neck of valve body.
Be threaded between inner flange nut 1 and the valve body 2, form the structure length of ball valve.Valve seal is housed tightens the side that the bedding and padding case 3 of mechanism is positioned at valve body, constitute the three-port structure form.At the passing hole place of spheroid, be the ball journal line with the diameter, be central point perpendicular to a radius of a ball top of this axis, milling goes out an interior square groove 8 that matches with square groove 17 outside valve rod 7 ends.At first on valve rod 7, be inserted in seal ring 9, in valve body 2, valve rod 7 is released pad case 3, be inserted in two-way dovetail seal ring 10 again, compress two-way dovetail seal ring 10, seal bedding and padding case 3 simultaneously with peach shape trim ring 11, thereafter valve fat 26 is injected peach shape trim ring inside groove 24, stage clip 20, two-way link stopper 12, flat nut 13 are inserted in valve rod 7 successively, tighten, put handle 14, flat nut 13 again, tighten, finish the general assembly of valve stem seal mechanism.In selecting Fig. 7 for use during the conjuncted handle 22 of two-way link stopper, assembly sequency is the peach shape trim ring 11 that continues, valve fat 26, put into the conjuncted handle 22 of two-way link stopper after the stage clip 20, tighten with flat nut 13 on top, thereafter seal ring 5 is embedded the sealed bed 6 of valve body 2, again ball core 4 is loaded in the valve body chamber, the outer square groove 17 of valve rod 7 is embedded in the interior square groove 8 of ball core 4.Put into gasket seal 23 at flange seal bed 21 places of valve body 2 again.Then seal ring 5 is embedded the sealed bed 6 of inner flange nut 1, inner flange nut 1 is screwed in valve body 2 tighten, make a pair of endoporus fluoroplastic seal ring 5 consistent be close to the both sides of ball core 4 symmetrically with latus rectum.
Trim ring is in company with rotation when preventing valve switch, the upper flange face of peach shape trim ring 11 is eccentric peach shape structure, it be located on bedding and padding case 3 edges location tappet 15 near, in case spline is moving, cut oiling groove 25 on the peach shape trim ring flanged surface, pack into stage clip 20 and be filled with valve fat 26 of the inside groove 24 of trim ring, valve fat has lubricated, sealing and rust inhibition.Has the auto-tensioning effect after the elastic force of stage clip main opposite end plane sealing and the wearing and tearing of shaft sealing bedding and padding, improve the valve stem seal performance, the oblique gesture 16 of the seal face of peach shape trim ring cooperates with two-way dovetail seal ring 10, when peach shape trim ring 11 is subjected to the screwing force of the tension force of stage clip 20 and nut, the dovetail of dovetail seal ring 11 produces the silk fabric distortion, obvolvent valve rod 7 has improved sealability.The switch limit element that two-way link stopper 12 is ball valves, it has the two-way position-limiting action that opens and closes of 90 degree clockwise and anticlockwise.The full open of ball valve is in same axis with the handle 14 or 22 of valve in valve body and is as the criterion; When handle 14 or 22 by plate moving to two-way link stopper 12 with locate tappet 15 and contact and stop rotation, be the ball valve air-tight state, two-way link stopper between peach shape trim ring and nut or the conjuncted handle of two-way link stopper central authorities have flat in square groove 18, cooperate with valve rod 7 threaded flat outer square grooves, issuable upper nut is loosening when so just having avoided the valve rod switch to rotate.
When the valve body of the integral (type) flange ball valve shown in the present embodiment, inner flange nut, bedding and padding case adopted malleable cast iron to be raw material, in addition hot galvanizing was so be called the zinc-plated ball valve of flange.
The utility model has the advantages that: modern design, compact conformation, good airproof performance, saving material, consumable quantity reduce by 20%～30%, simplified the ball valve processing technology, improved its decay resistance and increase the service life, the ball valve overall weight is light, specious, the upgrading products of the flange valve of can yet be regarded as.
