Abstract
The utility model relates to a circuit seal cover of a logging instrument housing. The circuit seal cover comprises a circuit seal cover body. A lower surface of the circuit seal cover body is provided with a tube extending downwards along a central axis. The tube is made integrated with the circuit seal cover body. The circuit seal cover also comprises an axial seal ring and a radial seal ring. The periphery of the lower surface of the circuit seal cover body is provided with a first seal groove used to install the radial seal ring. The radial seal ring is disposed in the first seal groove. The periphery of the tube is provided with a second seal groove used to install the axial seal ring. The axial seal ring is disposed in the second seal groove. Since the circuit seal cover is provided with the axial seal ring and the radial seal ring, the circuit seal cover has dual seal effect, and even though the axial seal ring leaks, the axial seal ring can play a role of further sealing, so that instruments and devices are safe.
Description
Technical field
The utility model relates to a kind of seal cover, is specifically related to a kind of logger housing circuit sealing lid.
Background technology
The part pipe nipple of logger as resistivity pipe nipple, sound wave pipe nipple etc., needs to lay circuit board at no magnetic shell body, and walks line and connect transducer and circuit board; This just needs circuit board to lay place's positive confinement, to isolate drilling fluid.The encapsulating method that the present seal cover that adopts adds " O " circle has two kinds: the one, and seal cover radially adds " O " circle, and the 2nd, seal cover axially adds " O " circle.These two kinds of methods the drilling fluid leakage problems all occurred when pressure and temperature is higher, caused the badly damaged of instrument.The main cause that this problem occurs is: under the HTHP situation, radial vibration or axial vibration cause radially or the gap appears in axial seal place.
The utility model content
Technical problem to be solved in the utility model provides a kind of logger housing circuit sealing lid, overcomes the single sealing ring of available technology adopting, occurs the drilling fluid seepage easily when pressure and temperature are higher, in the defective that becomes instrument damage.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of logger housing circuit sealing lid, comprise circuit sealing lid body, the lower surface of described circuit sealing lid body is provided with body along central axis extension downwards, described body and described circuit sealing lid body are made into integration, also comprise axial sealing ring and radial direction seal ring, the excircle of the lower surface of described circuit sealing lid body is provided with for first seal groove that radial direction seal ring is installed, and described radial direction seal ring is placed in described first seal groove; The excircle of described body is provided with for second seal groove that axial sealing ring is installed, and described axial sealing ring is placed in described second seal groove.
The beneficial effects of the utility model are: owing to be provided with the effect that axial sealing ring and radial direction seal ring can play dual-seal simultaneously, even an axial sealing ring leaks, axial sealing ring can play the effect of further sealing, makes instrument and equipment safer.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, also comprise diameter of axle sealing ring, described circuit sealing lid body lower edge processing one circle chamfering, described diameter of axle sealing ring is set on the described chamfering.
Adopt the beneficial effect of above-mentioned further scheme to be: because circuit sealing is covered body lower edge processing one circle chamfering, chamfering is provided with sealing ring, can seal the diameter of axle two aspects simultaneously, further strengthened sealing effectiveness, the entire circuit seal cover has been realized three-layer sealed effect, prevents from losing efficacy owing to the single sealing ring that vibration, high temperature, high pressure cause.Diameter of axle sealing ring is guaranteed the sealing at Instrument shell circuit board and line place.
Further, described chamfering is 1.5 * 45 °.
Adopt the beneficial effect of above-mentioned further scheme to be: to increase the sealability of instrument greatly, improved the stability of instrument, prolonged the useful life of instrument.
Further, described axial sealing ring, radial direction seal ring and diameter of axle sealing ring are the O RunddichtringO.
Description of drawings
Fig. 1 is the vertical view of a kind of logger housing of the utility model circuit sealing lid;
Fig. 2 is the generalized section of figure B-B direction;
Fig. 3 is the end view of a kind of logger housing of the utility model circuit sealing lid.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, the footpath Simmer ring chamfering of installing, 2, first seal groove installed of radial seal, 3, second seal groove installed of axial sealing ring, 4, circuit sealing lid body, 5, body.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of logger housing circuit sealing lid, comprise circuit sealing lid body 4, the lower surface of described circuit sealing lid body is provided with body along central axis extension downwards, described body 5 is made into integration with described circuit sealing lid body 1, also comprise axial sealing ring and radial direction seal ring, the excircle of the lower surface of described circuit sealing lid body is provided with for first seal groove 2 that radial direction seal ring is installed, and described radial direction seal ring is placed in described first seal groove 2; The excircle of described body is provided with for second seal groove 3 that axial sealing ring is installed, and described axial sealing ring is placed in described second seal groove 3.
Also comprise diameter of axle sealing ring, 1.5 * 45 ° of chamferings 1 of described circuit sealing lid body lower edge processing one circle, described diameter of axle sealing ring is set on the described chamfering 1.
The installation process of a kind of logger housing of the utility model circuit sealing lid: in first seal groove, first seal groove, place " O " circle, coat silicone grease lubricating grease; The utility model circuit sealing lid body is direction, therefore, after the quad seal circle at chamfering place is coated silicone grease lubricating grease, puts into the edge of respective housings seal groove.Housing seal groove place puts into seal cover, tightens four screws and gets final product.Chamfering 1 place guarantees radial and axial sealing simultaneously, and first seal groove, 2 places guarantee radial seal, and second seal groove, 3 places guarantee axial seal.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
