Abstract
The utility model relates to an inclined wedge type ball valve, belonging to the improvement of a ball valve. A ball core inside an integral type valve body is mainly made into an inclined wedge shape ball body. Double inclined surfaces of the ball core are corresponding to the through holes of the integral type valve body. The integral type valve body is correspondingly provided with a conical cavity whose shape and size are matched with the shape and the size of the ball core. A pre-tightening spring is arranged on the upper end of a valve core. When the ball core, a sealing protective pad inside the integral type valve body, and valve seats are abrased to generate a gap, the valve core is automatically pressed between the inclined wedge type valve seats by the pre-tightening spring, thereby, the sealing performance between the ball core and the integral type valve body is ensured, and the life of the ball valve is enhanced. The inclined wedge type ball valve has the advantages of strong sealing performance, simple structure, convenient maintenance, etc. The inclined wedge type ball valve can be used on the meters and the technics pipelines of the industrial departments of petroleum, a chemical industry, metallurgy, electric power, environmental protection, etc.
Description
The utility model relates to a kind of improvement of ball valve, particularly is applied in the ball valve that water, gas, wet goods non-erosion corruption medium on the industrial department and acid such as subtract at aggressive medium.
The ball valve of present industrial use divides from the valve body pattern, is divided into two classes, and a class is the divided casting ball valve, and another kind of is integral ball valve; The former advantage is that manufacturing process is simple, but connection forms because valve body is by flange plate, in the flange connection place, leakage phenomenon can occur, and when maintenance or replacing, dismantle the adapter that connects with valve body, and maintenance is extremely inconvenient.The latter though overcome above-mentioned shortcoming,, is worn and torn easily, and be can not get timely adjusting owing to be subjected to the effect of open and close torque and washing away of MEDIA FLOW repeatedly with the contacted Sealing of spool face; Cause the ball valve sealing decreased performance, shorten working life, if ball valve in the MEDIA FLOW of band solid particle, situation can be more serious.
The purpose of this utility model is to provide a kind of good seal performance, and inclined wedge type ball valve is easily overhauled or changed to long service life.
The inclined wedge type ball valve is fixed on the valve gap on the valve body by valve body, places ball core in the valve body and the valve seat that matches with the ball core, is contained in its lower end and the joining rotatingshaft composition of spool on the valve gap.The ball core is the inclined wedge-shaped spheroid, and its double inclined plane is corresponding with the valve body through hole, has the conical cavity that matches with spool shape, size in the valve body, and preloading spring is equipped with in the spool upper end.
Below in conjunction with embodiment shown in the drawings, the technical solution of the utility model is further described.
Accompanying drawing 1 is an embodiment's of the utility model a plan view, and Fig. 2 is the plan view of the inclined wedge-shaped centre of sphere, and Fig. 3 is the plan view of the inclined wedge-shaped centre of sphere.Among the figure: 1, valve body, 2, packing ring, 3, valve gap, 4, thin nut, 5, rotatingshaft, 6, packing ring, 7, elastic filler, 8, filler; 9, spring, 10, sheath, 12, valve seat, 12, the ball core, 13, protection pad.
The inclined wedge type ball valve comprises: the valve body (1) that is provided with the lateral direction penetrating hole, be fixed on the valve gap (3) on the valve body (1), close property packing ring (2) between valve body (1) and the valve gap (3), place ball core (12) in the valve body (1) and the valve seat (11) that matches with ball core (12), be fixed on rotatingshaft (5) on the valve gap (3) with hexagon thin nut (4) and pad (7).
Ball core (12) is made the inclined wedge-shaped spheroid, and its double inclined plane is corresponding with valve body (1) through hole, and spool (12) upper end face has groove, and the groove sliding sleeve is connected rotatingshaft (5) lower end; Valve body (1) through hole two ends are made flange plate and are connected with adapter, the centre has the conical cavity that matches with spool (12) shape, size, spool (12) places in the valve seat (11), the protection pad (13) of close property effect has been housed between valve seat (12) and the valve interior wall, and sheath (10) is equipped with in valve seat (11) bottom.
Filler (7) and elastic filler (8) are housed between rotatingshaft (5) and the valve gap sidewall, between rotatingshaft (5) lower end and the centre of sphere (12) end face preloading spring (9) are housed; Rotatingshaft (5) upper end connects with drive unit, and drive unit can be manual handle, also can be Pneumatic piston actuator.
The utility model in use, when the centre of sphere weares and teares the generation space with sealing protection pad (13), valve seat (11), preloading spring (7) is pressed into spool (12) between the inclined wedge type valve seat (11) automatically, thereby guaranteed the sealing between spool (12) and the valve body (1), the life-span of having improved ball valve.When ball valve maintenance or replacing, only need open valve gap (3), taking-up spool (12), valve seat accessories such as (11) can keep in repair.
Obviously, the utility model is owing to adopt jacking-type floating ball valve structure, and it is strong to have sealing, simple in structure, easy to maintenance, advantages such as long service life can be widely used on the instrument and process pipe of industrial departments such as oil, chemical industry, metallurgy, electric power, environmental protection.
Claims (3)
1, a kind of inclined wedge type ball valve is by valve body (1), be fixed on valve gap (3) on the valve body (1), place ball core (12) and the valve seat (11) that matches with ball core (12) in the valve body (1), be contained in valve gap (3) and go up the rotatingshaft (5) that its lower end connects with ball core (12) and form; It is characterized in that: said ball core (12) is the inclined wedge-shaped spheroid, and its double inclined plane is corresponding with valve body (1) through hole, the corresponding conical cavity that matches with spool (12) shape, size that has in the valve body (1), and preloading spring (9) is equipped with in spool (12) upper end.
2, by the described ball valve of claim 1, it is characterized in that described preloading spring (9) is enclosed within the rotatingshaft lower end.
