Abstract
A replacing sealing gasket ring groove is characterized in that a ring groove is arranged on a sealing surface of drilling equipments which are connected each other, and a backing ring groove which is movably engaged with the ring groove is arranged in the ring groove. The utility model has the advantages of simple structure, reliable sealing, and the like. Once the backing ring groove is broken, a new backing ring groove can be replaced, thereby maintaining easily, saving labor and money, guaranteeing the continuous usage of original equipments, and avoiding the unnecessary waste.
Description
The utility model relates to a kind of seal arrangement, particularly a kind of sealing gasket annular groove of connecting between the oil drilling facility of being used for.
A large amount of facility that use band 6B type such as preventers or 6BX type flange, blind plate in Process of Oil Well Drilling.Preventer is to be the safety installations that prevents that the too big generation blowout of underground oil and gas pressure is provided with, and the hydrogen sulfide gas that contains in oil, the rock gas has very strong corrosivity, and it can make the facility corrosion.At present, the connection of drilling well facility sealing is by the gasket ring in the bolt clamping pad annular groove on the flange, realizes by the distortion of gasket ring.Sealing gasket annular groove on the facility is processed by the SY5279.2-91 standard, and traditional method is directly to process the sealing gasket annular groove on facility, and this mode is easy to make the sealing gasket annular groove to damage because of corrosion.In order to address this problem, relevant technologies personnel have adopted the direct built-up welding of stainless steel on facility, and then on stainless steel, process the sealing gasket annular groove, though this mode can prevent the corrosion of sealing gasket annular groove, its processing technology difficulty is big, the manufacture cost height, and after repeated multiple times was used, the sealing gasket annular groove lost the effect of sealing because of distortion, wearing and tearing, if will repair, must remove to repair weigh several tons facility with main equipment and just can finish, not only take a lot of work but also take fund; If do not repair, whole facility will subscription rate, causes huge waste.
The purpose of this utility model just provides a kind of simple in structure, reliable sealing replacing formula sealing gasket annular groove.
The purpose of this utility model is to realize that by such technological scheme it is that a sealing surface connected to one another is provided with annular groove between the drilling well facility, is provided with in the annular groove with annular groove to be movingly gasket ring groove.The described facility that creep into can be blind plates, also can be 6B type or 6BX type flange, and the gasket ring groove is to make with the 2Cr13 stainless steel, during use, gasket ring is put into the gasket ring groove, compress gasket ring by the bolt on the flange and make it to be out of shape and realize connecting sealing.When the gasket ring groove loses seal action because of being out of shape, wearing and tearing, need only pull down the gasket ring groove of damage easily, change new gasket ring groove and get final product.
Owing to adopted technique scheme, the utlity model has advantages such as simple in structure, that sealing is reliable, in case the gasket ring groove damages, replaceable new gasket ring groove, keep in repair very convenient, not only saving of labor but also save money, and the continuation that has guaranteed original facility uses, and avoided unnecessary waste.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. drilling well facility; 2. annular groove; 3. gasket ring groove; 4.O shape seal ring.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is that a sealing surface connected to one another is provided with annular groove 2 between the drilling well facility 1, is provided with in the annular groove 2 with annular groove 2 to be movingly gasket ring groove 3.The described facility 1 that creep into can be blind plates, also can be 6B type or 6BX type flange, can also be other utensils that need be tightly connected; Gasket ring groove 3 is to make with the 2Cr13 stainless steel, and it is processed on C620～C630 engine lathe; Need only process annular groove 2 on the facility.During use, gasket ring is put into gasket ring groove 3, compress gasket ring by the bolt on the flange and make it to be out of shape and realize connecting sealing, the pressure that this gasket ring groove combination can be born 105MPa will not leak.When gasket ring groove 3 loses seal action because of being out of shape, wearing and tearing, need only pull down the gasket ring groove 3 of damage easily, change new gasket ring groove 3 and get final product.
As shown in Figure 1, in order to strengthen the sealing between gasket ring groove 3 and the annular groove 2, seal each other by the O-ring seals 4 that is arranged on the annular groove 2 between gasket ring groove 3 and the annular groove 2.O-ring seals 4 is to make with oil-resistant rubber material.
Claims (2)
1. change formula sealing gasket annular groove for one kind, it is characterized in that: a sealing surface connected to one another is provided with annular groove (2) between the drilling well facility (1), is provided with in the annular groove (2) with annular groove (2) to be movingly gasket ring groove (3).
2. replacing formula sealing gasket annular groove as claimed in claim 1 is characterized in that: seal each other by the O-ring seals (4) that is arranged on the annular groove (2) between gasket ring groove (3) and the annular groove (2).
