Hydraulic hose joint configuration
Strong uplift: hose connector is composed of a core tube and sheathed and clamped together with the sleeve, the sleeve is divided into two sections, the first section length is less than second and greater than the outer diameter of section second; the core tube is divided into two sections, the first section is the second section is the joint oil, rubber press section; the core pipe and the sleeve rubber press section cooperation is divided into three parts. The first part is a locking part, the second part is the part of the third part is the steel wire buckle, rubber press sealing parts; in the first part, the outer surface of the core pipe has a clamping groove, the sleeve surface along the circumferential direction with a snap ring matched; in the second part, the core tube the outer surface of a step and a groove, the inner surface of the sleeve ring a match; in the third part, the outer surface of the core pipe is provided with at least two corrugated groove, the sleeve surface is provided with at least two teeth groove. The utility model is used for the steel wire woven hose made of inner rubber layer, steel wire layer and outer rubber layer, and has the advantages of excellent pull proof performance, long service life and good sealing performance.
Self locking hose joint: a new type of hydraulic transmission, simple chemical package, easy maintenance and improved applicability. It has the advantages of convenient assembly and disassembly and wide adaptability. It is widely used in connecting all kinds of hose.
Well control hose connector: composed of a core rod and sheathed and connected with the sleeve is characterized in that the outer surface of the core rod and the sleeve on the surface along the circumferential direction of the corresponding is provided with at least 1 slots with each other and clasp. The utility model has the advantages of high temperature resistance, high pressure and resistance to pull out of the rubber tube, and is especially suitable for the connection hose of the oil well drilling control device.
Gas safety hose joint: a joint security guarantee gas transmission, including metal hose, Baotou, connecting pipe and a connecting nut, one end of the connecting pipe and hose, metal hoop pressure Baotou into one, the other end is connected with the inner hole of flange nut for different aperture of two parts, large hole diameter is slightly larger than the connection the flange is provided with internal thread, big hole depth is larger than the thickness of flange, hole diameter is slightly larger than the connecting pipe outer diameter and smaller than the outside diameter of the flange.
The utility model relates to an ultrahigh pressure drilling hose joint: an ultrahigh pressure drilling hose joint used on an oil field mining device, which comprises a sleeve and a connecting section which is connected with the core rod ring sleeve. The inner hole of the sleeve and the outer round surface of the core rod of the connecting section are correspondingly matched in turn, and the utility model is connected with an anti pulling out section, a sealing section and a transition section. Both the stripping section and the sealing section are respectively provided with a plurality of annular grooves on the excircle surface of the inner hole of the sleeve and the core rod, and are matched with or matched with the bulge. The test shows that when the working pressure of the inner cavity of the hose is 70MPa, the pulling resistance and the tightness of the hose joint can still be effectively guaranteed. The joint of the hose is welded because of the high temperature generated by the welding, and the locking of the sealing adhesive layer of the inner cavity of the rubber tube is effectively prevented from tearing by the locking of the transition section. Compared with the prior art, the production failure of the hose joint is eliminated, and the service cost is obviously reduced.
