Abstract
The utility model provides a packing ring used between a plunger pump combination valve and a packing box, which comprises a rubber ring, wherein an anticorrosive coating is arranged outside the rubber ring, a fiber net is arranged in the anticorrosive coating, a groove is arranged in the packing ring, and an outer groove is arranged on the outer side of the packing ring. The anticorrosive coating is made from polytetrafluoroethylene. The packing ring is characterized in that the structure is reasonably designed, the anticorrosive coating is added outside an existing rubber packing ring, which can keep the elasticity of the packing ring, thereby reaching better sealing effect, and preventing the packing seal from corroding by liquid, and the anticorrosive coating is not easy to craze and drop, which extends the service life of the packing ring. The utility model greatly reduces frequencies of changing the packing ring by stopping a machine, reduces intensity of labor of workers, and reduces manufacture cost of enterprises.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically a kind of seal ring that is used between plunger pump combination brake switch and proporting and Stuffing box.
Background technique
Plunger pump is used widely in the hydraulics field, the combination brake switch and proporting of plunger pump has the seal ring of rubber material with between Stuffing box, in actual use, aging, seriously corroded often appear in the sealing circle, cause the bad situation of sealing effect, in case this situation occurs, just need the termination of pumping maintenance, change seal ring, sometimes has only a few days the working life of a seal ring, like this frequent replacing seal ring had both increased staff's labor intensity, had improved the cost of production of enterprise again; Had artificially and addressed the above problem; designed the seal ring product that rubber ring has anticorrosive coat outward; though this series products has improved the corrosion resistance of seal ring; but because the ductility of anticorrosive coat is not as rubber material; the situation that the anticorrosive coat cracking takes place even come off through regular meeting during use, still effectively do not prolonged the working life of seal ring.
Summary of the invention
The purpose of this utility model provides a kind of seal ring that is used between plunger pump combination brake switch and proporting and Stuffing box, it can keep the elasticity of seal ring, reach the better seal effect, can prevent seal ring again, can avoid anticorrosive coat the situation of cracking to occur simultaneously effectively by liquid corrosion.
The utility model is achieved through the following technical solutions for achieving the above object: comprise rubber ring, rubber ring is provided with anticorrosive coat outward, is provided with fleece in the anticorrosive coat, and the seal ring inboard is provided with inner groovy, and the seal ring outside is provided with outer groove.The material of anticorrosive coat is a teflon.
Advantage of the present utility model is: reasonable in design, outside original rubber seal, increase anticorrosive coat, and can keep the elasticity of seal ring, reach the better seal effect, can prevent that again seal ring is by liquid corrosion; Anticorrosive coat is not easy to crack to come off, and has prolonged the working life of seal ring; Significantly reduced and shut down the number of times of changing seal ring, reduced staff's labor intensity, reduced the cost of production of enterprise.

Fig. 1 is the utility model structural representation.
Embodiment
The utility model comprises rubber ring 1, is provided with anticorrosive coat 2 outside the rubber ring 1, and rubber ring 1 has guaranteed that seal ring has certain elasticity, satisfies the required seal request of plunger pump, and anticorrosive coat 2 can prevent that seal ring from by liquid corrosion, increasing the service life; Be provided with fleece 3 in the anticorrosive coat 2, fleece 3 can increase the toughness of anticorrosive coat 2, and cracking came off when deformation took place to prevent to be squeezed anticorrosive coat 2; The seal ring inboard is provided with inner groovy 4, the seal ring outside is provided with outer groove 5, experiment shows, the thickness of the inside and outside both sides of anticorrosive coat is big more, the easy more cracking in both sides inside and outside when the extruding generation deformation that is subjected to Vertical direction, design inner groovy 4 is exactly to reduce the thickness of the inside and outside both sides of anticorrosive coat with the purpose of outer groove 5, prevents the anticorrosive coat cracking.The material of anticorrosive coat 2 is preferably teflon, and is superior because high temperature resistant, the corrosion-resistant and anti-air aging of teflon all belongs in same type of material, can prolong the working life of seal ring better; Anticorrosive coat 2 also can adopt other resistant material, but using effect is best with the polytetrafluoroethylmaterial material.
Claims (2)
1, a kind of seal ring that is used between plunger pump combination brake switch and proporting and Stuffing box, it is characterized in that: comprise rubber ring (1), rubber ring (1) is outer to be provided with anticorrosive coat (2), is provided with fleece (3) in the anticorrosive coat (2), the seal ring inboard is provided with inner groovy (4), and the seal ring outside is provided with outer groove (5).
