Abstract
The present invention relates to a sealing device of underwater equipment flexible thin lead wires, which comprises a cylindrical shell body with a bottom, wherein the bottom of the shell body is provided with a central hole; an end opening of the shell body is provided with screw threads. A compression nut is screwed on the screw threads of the end opening of the shell body. The compression nut is provided with a central hole through which a flexible thin lead wire passes. A lower pad, sealing material and an upper pad orderly close up in the shell body from the bottom to the end surface of the compression nut. The cylindrical surface of the upper pad is provided with a key groove. Radial screw holes are arranged in the corresponding positions of the shell body and the key groove. Stop screws are screwed in the screw holes. The end heads of the screws are positioned in the key groove of the upper pad. The lower pad, the sealing material and the upper pad are respectively provided with holes through which the flexible thin lead wire passes. The device of the present invention has the advantages of simple structure, reliable sealing and convenient disassembly. The largest use pressure can achieve 70MPa, and applicable temperature can achieve 200 DEG C. The present invention is suitable for linear sensors and flexible thin wire sealing on various occasions of low pressure, high pressure and high temperature.
Description
Technical field
The present invention relates to the seal arrangement of the soft ligament of underwater installation.
Background technique
Marine exploration and various under water with equipment in, all need the soft ligament of equipment is sealed, at present, mainly contain easy glue sealing and underwater electrical connector for the sealing of the soft ligament of underwater installation.Tamp aperture sealing with glue, have the following disadvantages: if the diameter of aperture is too little or the length of aperture when longer, glue has certain viscosity, is not easy to fill real whole aperture, easily produces leakage; When two pipe glue mix modulation, generally to react, the meeting heat release that has, glue has just produced bubble in the process of modulation, very unfavorable to sealing, has seepage; Can not use for a long time, the time has been grown, and glue is aging, and sealability just greatly reduces, and also inapplicable to the higher application of temperature; Adopt the glue envelope for precious metal sensor and optical fiber transducer, every dismounting maintains, safeguards once once destroyed, the cost height.With underwater electrical connector (as the product of Impulse company), many advantages are arranged, can transmit various electrical signal, sealing is reliable, dismantles more convenient.But many deficiencys are arranged also: the one, cost an arm and a leg; The 2nd, inapplicable to the application that electrical signal is had relatively high expectations, for example some chemical sensor is not just wished to connect in addition conductor; The 3rd, can't be applicable to optical fiber transducer.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, the seal arrangement of the soft ligament of reliable sealing underwater installation.
The seal arrangement of the soft ligament of underwater installation of the present invention, it is characterized in that it comprises the tubular shell of being with the end, center hole is arranged at the bottom at housing, the port of housing has screw thread, gland nut is twisted and is connected on the housing port screw thread, this gland nut has the center hole that passes through for soft ligament, adjacent successively between the end face to gland nut from the bottom in the housing have a underlay, sealing material and last pad, on the cylndrical surface of last pad keyway is arranged, have radially screw at housing with the keyway corresponding site, lock screw is twisted and is connected in this screw, and the termination of screw is arranged in the keyway of pad, at underlay, sealing material and last pad are respectively equipped with the hole of passing through soft ligament.
The sealing device structure of the soft ligament of underwater installation of the present invention is simple, and sealing is reliable, convenient disassembly, and maximum working pressure can reach 70Mpa, and Applicable temperature can reach 200 ℃.Be fit to the sealing of all kinds of low pressure high pressure and high-temperature field zygonema shape sensor and soft fine rule.
Description of drawings
Fig. 1 is the schematic diagram of sealing device of the soft ligament of underwater installation.
Embodiment
With reference to Fig. 1; the seal arrangement of the soft ligament of underwater installation of the present invention comprises the tubular shell 2 of being with the end; in the bottom of housing center hole 9 is arranged; the port of housing has screw thread; gland nut 1 is twisted and is connected on the housing port screw thread; this gland nut 1 has the center hole that passes through for soft ligament; adjacent successively between the end face to gland nut from the bottom in the housing have a underlay 6; sealing material 5 and last pad 4; on the cylndrical surface of last pad 4 keyway 8 is arranged; housing have radially screw with the keyway corresponding site, lock screw 3 is twisted and is connected in this screw, the termination of screw 3 is arranged in fills up 4 keyway; can prevent the pad rotation, protect soft ligament.Underlay 6, sealing material 5 and on pad 4 be respectively equipped with the hole of passing through of passing through soft ligament 7.Be the convenient fairlead that bores, can make a side of pad and underlay have groove respectively as shown in the figure.Sealing material can adopt teflon, viton or neoprene, compresses sealing material by gland nut and realizes sealing.
Can earlier lead-in wire be passed successively underlay, sealing material during installation and go up pad, then this part be put into housing, the center hole of gland nut and housing bottom is stretched out at the lead-in wire two ends respectively, is screwed into lock screw, tightens gland nut, guarantees sealing.Because lock screw can guarantee that when tightening gland nut, last pad does not rotate, therefore can protect soft ligament.When this installs under water, can be because the pressure of water be pressed tighter and tighter.
