Description

Waterproof casing snap joint
Technical field
The utility model relates to a kind of piecing devices, more particularly, relates to the snap joint that is used to connect waterproof casing in a kind of prospect pit process at sea.
Background technology
Must verify the reserves of oil gas at sea when exploring for oil by the well of prying into, but the drilling process of marine prospect pit is different with land, must use waterproof casing to come insulating sea water, so that the borehole wall is protected.Because seawater is darker; can not use integrated disrance sleeve; the purpose of insulating sea water, the protection borehole wall could be realized after many disrance sleeves must being tightly connected mutually, therefore, between two waterproof casings, a connector that two waterproof casings are tightly connected must be used.And the connector that is used to connect waterproof casing at present mostly is outer receipts formula joint, this kind circumscribed joint all is to rely on the elasticity of tightening or adjust 12 screws to realize when installation and removal, thereby cause this joint comparatively strict, and in operation, also comparatively bother the requirement of spigot and socket relative position.
Summary of the invention
The purpose of this utility model provides a kind of waterproof casing snap joint, and this waterproof casing snap joint has solved existing joint troublesome poeration effectively, the problem that spigot and socket relative position are had relatively high expectations.
Waterproof casing snap joint in the utility model includes socket and spigot, wherein said socket and spigot are fixedly connected on the two ends of waterproof casing respectively, described socket wall within it is provided with an annular groove, in this annular groove, be provided with a snap ring, that described spigot is provided with on its outside wall surface is one corresponding with described annular groove, be used to the groove that card is established described snap ring, simultaneously, described socket wall within it is provided with and is used to the groove that card is established seal, and is arranged with the seal that can seal socket and spigot in this groove.
In addition, described socket is provided with two guiding conical surfaces in the wall within it, corresponding with this two guiding conical surface, on the outside wall surface of described spigot, be provided with two taper seats that can fit with described guiding conical surface, spigot is aimed the place when engaging easily with socket.
In addition, described socket and spigot are fixed together with the two ends of the waterproof casing mode with welding respectively.
In addition, described annular groove is provided with the perforation that a plurality of and described socket outer wall is connected in its bottom, and is corresponding with each perforation, is provided with a plurality of screws on snap ring, and in this screw, being provided with the bolt of boring a hole on the perforation socket wall, described perforation, screw and bolt are five.
Snap joint anti-shearing force in the utility model is big, and safety factor is higher, and carries out axial location by two groups of conical surfaces, and the stability that makes waterproof casing impact in ocean current is better.In addition, the snap joint in the utility model is easy and simple to handle, time saving and energy saving, obviously can increase work efficiency.
Description of drawings
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 be in the utility model waterproof casing snap joint partly cut open structural representation;
Fig. 2 is the schematic side view of waterproof casing snap joint in the utility model;
Fig. 3 is the schematic side view of another embodiment of waterproof casing snap joint in the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model snap joint of being used to connect waterproof casing includes socket 1, spigot 2, snap ring 3, sealing ring 4 and bolt 5.Wherein socket 1 and spigot 2 are welded on the two ends of waterproof casing 6 respectively.
As shown in Figure 1, socket 1 wall within it is provided with an annular groove 10, and this annular groove 10 is used to be provided with snap ring 3.Simultaneously, socket 1 within it on the wall side near annular groove 10 be provided with a groove 11, this groove 11 is used for card and establishes sealing ring 4, in addition, hold the position for socket 1 is relatively easily supportted when being connected with spigot 2, be provided with two guiding conical surfaces 12 and 13 at the inwall two ends of socket 1.Spigot 2 wall within it is provided with a groove 20, and this groove 20 is corresponding with the annular groove 10 of socket 1.Simultaneously, corresponding with the guiding conical surface 12,13 on socket 1 internal face, on the outside wall surface of spigot 2, be provided with two taper seats 21 and 22.When spigot 2 and socket 1 fasten when being connected, groove 20 is just corresponding with annular groove 10, simultaneously, taper seat 21,22 and guiding conical surface 12 and 13 fit tightly, and the snap ring 3 that is fastened in the annular groove 10 is fastened in groove 20 and the annular groove 10, thereby socket 1 is locked together in reliably with spigot 2.
As depicted in figs. 1 and 2, socket 1 is provided with three strips perforation 14 in the bottom of annular groove 10, bores a hole 14 correspondingly with this strip, is provided with three screws 30 on snap ring 3, utilizes this screw 30, passes strip perforation 14 and be provided with three bolts 5.Strip perforation 14 portion within it can be provided with sealing water plug, enters into waterproof casing 6 inside further to prevent seawater.
When assembling and installation waterproof casing 6, earlier socket 1 and spigot 2 are welded on the two ends of waterproof casing 6 respectively, and in the annular groove 10 of socket 1, are arranged with snap ring 3, at this moment, this snap ring 3 is in and tightens up shape.Then with 6 butt joints of root waterproof casing, the spigot 2 that is about to a waterproof casing is inserted into socket 1 inside of another root waterproof casing end, when the groove on the spigot 2 20 when annular groove 10 in the socket 1 aligns, snap ring 3 can drop in the groove 20 of spigot 2 automatically, thereby two waterproof casings 6 are locked together in together reliably, and then many waterproof casings 6 can be linked together.After prospect pit is finished, most of waterproof casings 6 all need to reuse, therefore, after when dismounting, only needing mentioning waterproof casing, screw three bolts 5, snap ring 3 is opened equably, promptly break away from spigot 2, thereby can easily spigot 2 and socket 1 be separated, and then waterproof casing is separated.
As shown in Figure 3, can evenly open in order to make snap ring 3, the bolt on snap ring 3 can be five bolts 5.
In sum, the snap joint in the utility model is after being used for waterproof casing, and it has, and anti-shearing force is big, and safety factor is higher, and carries out axial location by two groups of conical surfaces, and the stability that makes waterproof casing impact in ocean current is better.In addition, the snap joint in the utility model is easy and simple to handle, time saving and energy saving, obviously can increase work efficiency.
In addition; though above-mentioned specific embodiment to snap joint in the utility model is described; but can not be as protection domain of the present utility model; because those of skill in the art as the present technique field; it is modified a little or changes is more or less freely; but these are modified with improving and are not all broken away from design spirit of the present utility model, and every equivalence of having done in the design spirit that does not break away from the utility model changes or modification all should be thought and falls into protection domain of the present utility model.
