Description

Self-balancing type self compensation seal ball-valve
Technical field
The utility model relates to a kind of self-balancing type self compensation seal ball-valve; Belong to valve technology field.
Background technique
At present, various types of ball valves, its import and export all directly communicate with the valve body chamber, and pressure fluid acts directly on the ball valve core, realize opening and closing by 90 degree rotations.When higher to pressure, when the bigger ball valve of latus rectum is opened or closed, because fluid pressure action, have and make the ball valve core press to valve seat or live axle very energetically, cause therefore that to handle moment of torsion very big or the sealing position is destroyed.And owing to above reason, also influenced big latus rectum, the development of high pressure ball valve.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of self-balancing type self compensation seal ball-valve; This ball valve passes through the pressure fluid controlled simultaneously and the both sides that act on the ball valve core of symmetry, realizes the pressure self balancing.Simultaneously by a kind of to ball valve core self compensation sealing means, realize the light open and close of ball valve, and can design and manufacture than than the bigger ball valve of the higher latus rectum of present pressure.
The technological scheme that its technical problem that solves the utility model adopts: it is made up of lid shape cap, plain cushion, handle, rotating shaft, valve body, ball valve core, valve gap, loaded spring, self compensation packed-piston, seal ring, bolt; Valve gap is by being bolted on the valve body, and the self compensation packed-piston is contained in the valve gap, and the ball valve core is contained in self compensation packed-piston inboard, and loaded spring is contained between valve gap and the self compensation packed-piston; Valve body right-hand member passage does not directly communicate with body cavity, and communicates with last bottom flange passage, and another passage directly communicates with body cavity; Two of both sides self compensation packed-pistons must be measure-alike up and down, the shape unanimity; The ball valve core is provided with the spool open channel that communicates with straight hole on the non-tight surface except that a clear opening; Handle is connected with the ball valve core, is fixed on the valve body by lid shape cap, between lid shape cap and the handle plain cushion is housed.
The beneficial effects of the utility model are: realized the pressure self balancing owing to being subjected to the effect of equal pressure fluid simultaneously on ball valve core and two the self compensation packed-pistons.Simultaneously, by the self compensation packed-piston of bears against ball spool with have a keying function that the ball valve core that opens and closes passage is realized ball valve; Therefore this valve operating torque can greatly reduce, and under the uniform pressure grade, the latus rectum scope can obtain very big expansion simultaneously; Be suitable for the break-make control of pressure fluid.

Embodiment
See also Fig. 1 to Fig. 2; It is made up of lid shape cap (1), plain cushion (2), handle (3), rotating shaft (4), valve body (5), ball valve core (6), valve gap (7), loaded spring (8), packed-piston (9), seal ring (10), bolt (11); Valve gap (7) is fixed on the valve body (5) by bolt (11), self compensation packed-piston (9) is contained in the valve gap (7), ball valve core (6) is contained in self compensation packed-piston (9) inboard, loaded spring (8) is contained between valve gap (7) and the self compensation packed-piston (9), valve body right-hand member passage (12) does not directly communicate with valve body (5) inner chamber, and communicate with last bottom flange passage (14), another passage directly communicates with valve body (5) inner chamber; Two of both sides self compensation packed-pistons (9) must be measure-alike up and down, the shape unanimity; Ball valve core (6) is contained between two self compensation packed-pistons (9); Ball valve core (6) is provided with the spool open channel (15) that communicates with straight hole on the non-tight surface except that a clear opening; Handle (3) is connected with ball valve core (6), is fixed on the valve body (5) by lid shape cap (1), between lid shape cap (1) and the handle (3) plain cushion (2) is housed.
Valve body (5), inner chamber are circle hole shape, and two fens its area sums of branch road of suction side are equal to or slightly less than the latus rectum requirement.Self compensation packed-piston (9) and ball valve core (6) contacting side area are slightly less than the opposite side area, guarantee that self compensation packed-piston (9) bears against ball spool (6) seals like this when the pressure fluid effect is on it.Should guarantee two self compensation packed-piston (9) shapes simultaneously, consistent size.Ball valve core (6) clear opening and spool open channel (15) area that communicates with it all should meet the relevant technologies requirement.Loaded spring power should be able to overcome self compensation packed-piston (9) frictional force, makes it provide an initial sealing power to ball valve core (6).The basic functional principle of self balancing self compensation seal ball-valve be pressure fluid by the valve body import respectively symmetry enter and act on ball valve core (6) both sides and two the self compensation packed-pistons (9).Because the area that self compensation packed-piston (9) and ball valve core (6) contacts a side is less than the opposite side area, institute and can compensate after wearing and tearing automatically so that the one vertical compression is guaranteed to seal to ball valve core (6).Loaded spring (8) provides a pretightening force to participate in sealing; The spool open channel (15) that has clear opening and communicate with it because of ball valve core (6) is so can realize opening and closing during in 90 degree rotations when live axle.
