Abstract
The utility model relates to an anti-leak self-cleaning ball valve, in particular to an anti-leak self-cleaning ball valve, which comprises a valve body, a valve core, a valve stem for driving the valve core to rotate and a sealing ring mounted between the valve body and the valve core. The anti-leak self-cleaning ball valve is characterized in that an annular cleaning ring matching with the valve core is mounted at a liquid inlet of the sealing ring, the cleaning ring is fixed by a nut which is provided with a through hole and matches with the valve body, and a spring is arranged between the nut and the cleaning ring. The anti-leak self-cleaning ball valve is an improvement on the basis of the existing ball valve, because the cleaning ring is additionally arranged between the valve core and the sealing ring and simultaneously the rotatable valve core and a seal pair of the valve stem are equipped with springs, the ball valve is fine in sealing effect and has functions of self-cleaning, automatically eliminating gaps and the like, and then the service life of the ball valve can be prolonged greatly.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of anti-leak automatically cleaning ball valve.
Background technique
Ball valve is the valve that is widely adopted in recent years, and it has advantages such as fluid resistance is little, simple in structure, applied widely, operation is nimble.Simultaneously, ball valve when standard-sized sheet, full cut-off, the sealing surface of spheroid spool and seal ring and media isolated, at a high speed the medium by valve can the etch sealing surface, has increased the working life of ball valve.But when ball valve is closed, spool just contacts with medium, owing to reasons such as impurity in the medium or chemical corrosions, will form corrosion layer or be stained with some impurity at spool and medium contact surface, when valve switch, impurity will enter between spool and the Sealing like this, makes and produces wearing and tearing between spool and the Sealing, after wearing and tearing acquire a certain degree, will make seal failure, just cause the leakage of ball valve.Sealing between valve rod and the valve body simultaneously also can cause the leakage between valve rod and the valve body owing to long-term the use produces wearing and tearing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and defective, provides a kind of and can remove the impurity on the spool automatically when opening and closing ball valve, can compensate automatically simultaneously because the anti-leak automatically cleaning ball valve in the sealing pair gap that wearing and tearing cause.
For realizing the purpose of this utility model, the technological scheme that is adopted is: a kind of anti-leak automatically cleaning ball valve, comprise the valve rod of valve body, spool, the rotation of drive spool and be installed in seal ring between valve body, the spool, it is characterized in that the ring-type wiper ring that matches with spool being installed at the liquid entering hole of seal ring, wiper ring is fixed by the nut of the band through hole that matches with valve body, between nut and wiper ring spring is installed.
Seal ring and belleville spring are installed between above-mentioned valve rod and the valve body from the bottom to top.
Above-mentioned ring-type wiper ring is made by pottery or Hardmetal materials.
The utility model is the improvement on existing ball valve basis, but has the good sealing effect automatically cleaning, eliminate function such as gap automatically, and improved the working life of ball valve greatly.The ring-type wiper ring of being made by hard material has been installed in the import of seal ring in ball valve, make the utility model in use, impurity particle on the spool can be scraped by wiper ring, can guarantee effectively that impurity particle can not enter in the sealing pair of spool and seal ring formation the working life of having improved ball valve.In order to prevent sealing pair wearing and tearing in use, cause the leakage of sealing pair simultaneously, between spool and wiper ring and valve rod and seal ring, spring is installed respectively, so just can eliminate the gap that wearing and tearing cause automatically.
Description of drawings
Structural representation when accompanying drawing 1 is opened for the utility model;
Accompanying drawing 2 is the I structure for amplifying schematic representation of the utility model accompanying drawing 1.
Embodiment
As shown in Figure 1, 2, the seal ring 6 of ball valve left and right sides of spool 8 when opening just closely contacts with spool 8 with the ring-type wiper ring 9 that a left side is surveyed, and plays seal action.The annular wiper ring is fixed in the valve body 2 by the nut 3 of band through hole, and seal ring 10 and belleville spring 11 are installed on the top of original Sealing 7 between nut and wiper ring valve rod 5 and valve body 2.When ball valve was closed, spool will some expose in the import of seal ring 6, directly contacted with liquid or gas in the pipeline, will form corrosion layer like this or be stained with impurity on the exposed surface of spool.When needs were opened ball valve, handle with sleeve 1 drove valve core rotation by valve rod, just the corrosion layer or the impurity of spool face can be wiped off by annular wiper ring, just can effectively prolong the sealing effect between the ball valve sealing pair, and improved the working life of ball valve greatly.Simultaneously on the sealing pair of all right one way or the other revolving part spool, valve rod, be separately installed with spring 4 and belleville spring 11, so just can eliminate automatically because the gap that wearing and tearing cause.
Claims (3)
