Abstract
The utility model relates to a pipe connector and its sealing device, comprising a pipe connector body, a special gasket and an O-type rubber sealing ring. The end face of the pipe connector body is provided with an O-type slot of the rubber sealing ring. The utility model is characterized in that the leakage and the seepage problems of the prior hydraulic system of machine tool caused by pressure impact and nonnormality of a screw and a spot face can be solved. The utility model can also lengthen the life of the component and save the oil material.
Description
The utility model relates to machinery hydraulic system pipeline sealing technique.
In the hydraulic system pipeline and pipe joint must be arranged, pipe joint is mounted on a certain component/(these component are hereinafter to be referred as body).The Placement of pipe joint and body has two kinds: (1) angle of thread is 60 ° or 55 °, and middle footpath is 1/16 tapering pipe pitch thread.(2) metric system closely-pitched or straight tube pitch thread made in Great Britain.The former generally is used for low pressure, and the latter generally is used for the mesohigh system.For the latter, if internal thread and aperture out of plumb will leakage of oils, although the technologist designs a lot of ways, the off plumb phenomenon is difficult to eradicate, and card is more cannot say for sure in workman's hand tapping; People make packing ring with materials such as red copper, aluminium, rubber, hope can be got rid of leakage of oil, because commutation is frequent in the system, and speed is generally all very fast, and hydraulic shock and commutating speed are inversely proportional to, and impact must exist, and cause red copper or aluminium matter packing ring to be out of shape once more, fittings body takes place loosening, and seepage or gas leakage still produce, and waste oil plant, befouling environment, hydraulic element life-span reduce.
The purpose of the utility model is for the seepage of drain joint and body joint, and a kind of pipe joint and seal arrangement thereof are provided.
The utility model is achieved in that and promptly adopts encapsulating method twice, union body (1) end face be processed with screw thread one train under zero type rubber seal ring recess (5); Union body (a 1) special packing ring of underneath (2), this packing ring simultaneously are protruding spheres, and another side is plane and zero type rubber seal ring recess (5); In zero type ring recess (5) of special packing ring (2), put one zero type rubber seal (3).Like this, union body (1) and body (4) are when tightening, and special packing ring (2) seals by zero type rubber seal (3) with body (4); Special packing ring (2) and the effect generation tight circumference that contact of union body (1) by the spin friction pressurization; So far, although internal thread and plane crooked (in 2 °), because of union body (1) and packing ring ∥ (2) contacting point are a circle forever, so crooked being repaired and obtain reliable sealing.Again because of packing ring (2) material adopt 45 or 40Cr can play the effect of butterfly spring through heat treatment, effectively hydraulic shock in the absorption system makes the unlikely loosening and seepage of union body (1).
The utility model has the advantages that the disposable solution of leakage, leakage problems that present machine tool hydraulic system is caused because of screw thread and spot face out of plumb and compression shock, and make that system works is stable, component life prolongs, save oil plant.
Description of drawings: (1) be union body, (2) for special packing ring, (3) be that zero type rubber seal, (4) body, (5) are zero RunddichtringO groove.
Accompanying drawing is the utility model structural representation.
Claims (3)
1, a kind of pipe joint and seal arrangement thereof, form by union body and zero type rubber seal, it is characterized in that union body (1) be connected with body (4) end face be processed with screw thread one train under zero type rubber seal ring recess (5), union body (a 1) special packing ring of underneath (2).
2, pipe joint according to claim 1 and seal arrangement thereof, the one side that it is characterized in that special packing ring (2) is protruding sphere, another side is plane and zero type rubber seal ring recess (5).
3, pipe joint according to claim 2 and seal arrangement thereof is characterized in that special packing ring (2) is employing 45 or the heat treated material of 40Cr process.
