Abstract
The utility model discloses a ceramic valve core valve which can be hermetically opened and closed. The utility model is composed of a ceramic valve core body, a valve body and a handwheel, wherein, the valve core body in the valve is connected with the valve body. The ceramic valve core valve which can be hermetically opened and closed having the characteristics of simple structure, stable performance, environmental protection, sanitation, convenient operation, etc. can be used for heating, running water and various oil pipelines.
Description
The utility model relates to a kind of valve, is a kind of ball valve that is opened and closed by old-fashioned ball core sealing specifically, is improved to a kind of valve that is opened and closed by the ceramic core sealing.
Existing ball valve on the market, join the sealing configuration that the polytetrafluoroethylene sealing is formed by the ball core without exception, after the structural imperfection of this ball valve has been to pass through the switch keying of frequent repetition, valve rod afterbody and ball core groove combination joint, can cause gap and wearing and tearing, the result opens and closes not in place and water clock water, and above-described product can not be dismantled maintenance, must change, for users bring inconvenience.
The utility model purpose is to overcome improvement the problems referred to above, provides a kind of simple in structure, has the valve of the ceramic seal structure that can be easy to remove and repair.
The ceramic core structure valve that the utility model provides, form by ceramics structure spool and valve body handwheel three parts, ceramic plate structure spool, comprise the valve core rotation positioning rod in ceramic core ectosome and the ectosome and open and close the ceramic plate of seal action and the silica gel sealing pad of ceramics lower end, " O " shape seal ring at positioning rod middle part.Valve comprises valve body, the scyewed joint on the rotation valve rod of porcelain core positioning rod upper end is used in the valve body handwheel, valve body and the spool.Ceramics and valve rod connect in the spool, and valve rod is passed by porcelain core ectosome middle part, connects the porcelain core housing.The toothed section on handwheel and valve rod top connects, and is fixed by screw tightening.Only need to press Directional Sign lightly during operation and rotate handwheel, form the location, reach keying by the location side of valve rod afterbody and the salient point at valve core inwall place.
Concrete structure of the present utility model is showed by following examples and accompanying drawing thereof.
Figure: 1, ceramic valve core body; 2, valve core rod; 3, screw; 4, handwheel; 5, seal ring; 6, seal ring; 7, valve body; 8, sealing gasket; 9, ceramics; 10, ceramics.
As shown in the figure, this ceramics sealing opening/shutting valve is by 1 ceramic valve core body, 2 valve core rods, and 3 screws, 4 handwheels, 5 seal rings, 6 seal rings, 7 valve bodies, 8 sealing gaskets, 9 ceramics, 10 ceramics are formed.Ceramic valve core body 1 and valve core rod 2 and seal ring 5,6, sealing gasket 8 and ceramics 9,10 are a synthetic integral body.Ceramic valve core body intermediate portion is provided with outside thread, ceramic valve core body 1 connects with valve body 7 by the outside thread that the middle part is provided with, valve core rod 2 and ceramic valve core body 1 are that mesopore by ceramic valve core body 1 is by the close-fitting sealed attachment of the seal ring on valve core rod 2 central slot 5 with valve core, ceramics 1 connects with two place's salient points of valve rod 2 lower ends by two place's concave points on the plane own, ceramics 10 locates two salient points by outer ring own and two outer concave points of valve core lower end mouth inwall are fixed in the valve core, ceramics 9,10 high precision plane by plane own are bonded together, play sealing keying effect, sealing gasket 8 is by the external diameter of inner stainless steel spring support own and the tight size of valve core lower end mouth, close-fitting connects, valve core 1 be provided with rubber seal 6 between valve body 7 connects, seal ring 6 seals, and handwheel 4 plays the rotating valve core bar and drives ceramics 9,10 and play the keying effect.Screw 3 plays handwheel 4 is fixed on effect on the valve core rod.Ceramics 9 and ceramics 10 in the present embodiment have wear-resisting function, seal ring 5 and seal ring 6 and sealing gasket 8 are made by silica gel, have oil resistant, characteristics such as alkaline-resisting, sour, high temperature resistant, Fu Shi function never, above characteristics have improved that the groove on the ball cored structure contacts with the valve rod afterbody in the old-fashioned valve, and use can cause shortcomings such as gap, wearing and tearing for a long time.
Compared with former old-fashioned valve, this valve mechanism is simple, understands, and is convenient for production, skill The art stable performance itself has simultaneously this valve operation use of characteristics of environmental protection, health very Convenience, in the middle of running water and oil product and caliduct.
