Abstract
The utility model relates to a softly sealed eccentric butterfly valve. The utility model is characterized in that the connection between a valve plate and a valve rod is realized through bolts and spring washers; the upper periphery of the valve plate is provided with an annular dovetail groove in which a sealing ring is arranged; a sealing belt of a spherical surface is arranged away from an axis in the position of a valve body contacting surface which is corresponding to the periphery of the valve plate; an operating rod is additionally arranged at one end of a handle arranged at the upper end of the valve rod, and positioning locking devices are arranged at the other end of the handle and on a valve body which is corresponding to the handle. The utility model has the advantages that a mechanical connection structure in the publicly known technology is effectively replaced, the structure is simple, materials are saved, the sealing ring arranged on the valve plate can be replaced quickly and conveniently, the unseating phenomenon is avoided, and the circulation characteristic of the utility model is improved.
Description
The utility model belongs to F16K valve class technology, particularly relates to a kind of soft seal eccentric-butterfly-valve.
Known soft seal eccentric structure butterfly valve, because this body structure is limit, though the soft seal pair can not be contained on the valve body, need be with being packed on the valve plate by mechanical connection by labyrinths that part constituted such as pressure ring and border bolts, and need to consider the side sealing problem.Therefore exist deficiency to be, the structure of this complexity not only can cause the waste of the too fat to move and material of valve mechanism, but also can be under operating mode vibration situation, the generation bolt looseness, causes the phenomenon of knocking over, the more important thing is the circulating resistance that has increased medium greatly.
The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of simple in structure and install convenient and reduce the soft seal eccentric-butterfly-valve of medium circulating resistance.
The purpose of this utility model is achieved in that
The utility model is by be coated with valve rod in valve body, valve rod respectively with valve body on, contact down on the ring surface of combination and all have circular groove, in its groove seal ring is housed, valve rod by body cavity is connected and installed with valve plate, the valve rod upper end that passes valve body and with valve body on end in contact install on the basis that handle forms again by fixing pin be to realize the purpose of this utility model like this, the concrete linkage structure that valve rod by body cavity in above-mentioned is connected and installed with valve plate is, being connected between valve plate and the valve rod is to rely on the bolt and spring washer circle to realize, periphery on valve plate has annular dovetail slot, " O " seal ring is housed in this groove, with the position of the peripheral pairing valve body surface of contact of valve plate and off-axis on be shaped on the ball face sealing band; Also add operating stem at an above-mentioned end that is loaded on the handle of valve rod upper end, the interior rod end of its operating stem has blind hole, priority mounting spring, ball in blind hole, being shaped on the valve body corresponding with the blind hole on the operating stem can the half movable locating slot that embeds ball, at the other end of handle with also be shaped on positioning and locking device on the valve body of correspondence with it.
The concrete structure of the positioning and locking device that is shaped on the other end of above-mentioned handle and the corresponding with it valve body is, the other end at handle is shaped on the positioning hole that can install locating stud, is shaped on two positioning holes with span on the pairing valve body of the positioning hole of the handle position.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Valve rod 2 is installed on the valve body 1, contacts with valve body on the valve rod ring surface of combination and have circular groove 20, " O " RunddichtringO 19 of in its groove, packing into; And have circular groove 6 on the valve rod two place's ring surfaces that contact combination on the valve body, " O " RunddichtringO 7 also is housed in its groove.On the valve rod side in body cavity valve plate 3 is housed, only depends on spring washer 5 and bolt 4 to be connected and fixed between valve plate and the valve rod, wherein spring washer can prevent the leakage at bolt hole place effectively.Connect above-mentioned periphery and have annular dovetail slot 21, in this groove, " O " RunddichtringO 18 is packed into, realize that need not mechanical connection has just finished sealing of the present utility model, and overcome the knocking over phenomenon effectively at valve plate.In addition, with the position of pairing valve body surface of contact of valve plate periphery and off-axis on the also corresponding ball face sealing band 22 that is shaped on, solved the side leakage problem.When closing the utility model, " O " RunddichtringO 18 on the valve plate and the ball face sealing band on the valve body 22 form a circular seal pair, reach to cooperate accurately, need not the big effect that interference just can well seal and operational torque is little.Repeat in the valve rod upper end that passes valve body the handle 10 that contacts with valve body also is housed, in handle, be shaped on pin-and-hole 12, be connected and fixed handle and valve rod by this pin-and-hole fixing pin 11 of packing into, add operating stem 13 at an end of handle by being threaded, the interior rod end of its operating stem has blind hole 14, priority mounting spring 15 in blind hole, ball 16, the partly activity that is shaped on the valve body corresponding with the blind hole on the operating stem embeds the locating slot 17 of ball, the other end at handle is shaped on positioning hole 9, be shaped on two positioning holes 8 with span on the pairing valve body of the positioning hole of the handle position, these two positioning holes are respectively the positioning hole of opening and closing of the present utility model.The rotating operation bar can be aimed at the positioning hole of handle respectively with the positioning hole of opening and close on the valve body, install the locating stud (not shown) again and position, in order that prevent the loosening or misoperation of handle, promptly guarantees adjusting of the present utility model and gets the stability of closing.
Advantage and the good effect that the utlity model has are: owing to only depend on bolt between valve plate and the valve rod Connect, therefore not only simple in structure, and when " O " RunddichtringO on the needs replacing valve plate, Just can quick and conveniently take off valve plate changes and just can. Be equipped with owing to having in it at the valve plate periphery again The annular dovetail slot of " O " RunddichtringO and in the valve body contact-making surface relevant bits corresponding with valve plate periphery Be set up and be shaped with sphere sealing strip and form the circular seal pair, so both effectively replaced in the known technology Mechanical connecting structure has again advantage simple in structure and that save material, and has avoided the knocking over phenomenon, Also need not to consider the side leakage problem, but also improved widely flow characteristics of the present utility model again. In addition After handle of the present utility model installs positioning and locking device additional, reach and prevent the loosening and mistake of handle outward, Operate and guarantee the purpose of the modification stability that the utility model is opened or closed.
