Abstract

The invention relates to a land and submerged high-pressure resistant explosion-proof wire outlet device, which comprises a bed plate, wherein the bottom of the bed plate is provided with a flange inside which an outlet hole is formed; a lead wire has a tapered structure; a tapered high-pressure resistant explosion-proof sealing ring is sleeved in the tapered hole; a jointing face between the bedplate and a wire outlet device of a motor is provided with a high-pressure resistant sealing ring and an explosion-proof face; a flange cover is fixed on the upper part of the bed plate; and the part, outside an outlet, of an outgoing line is sleeved with a high pressure sealed hose. The high-pressure resistant explosion-proof wire outlet device has a rational structural design, high sealing properties, high pressure resistance and explosion-proof performance, is quick and convenient to wire, can effectively fulfill the aim of sealing the outgoing line and bear the water pressure of 8MPa without leakage to achieve good sealing effects, and is particularly suitable for use in explosion-proof occasions with high pressure media.

Description

technical field [0001] The invention belongs to the technical field of motor accessory parts, and relates to a high-voltage land-submersible dual-purpose explosion-proof outlet device. Background technique [0002] In the known technology, the flameproof motor can only be used in places with explosive gas, and the internal cables of the flameproof motor are all introduced into the main junction box of the motor through terminal bolts and terminal sleeves; the flameproof motor and its Outgoing devices cannot be used in highly pressurized liquid or gas environments. In order to develop the motor for high-pressure land-submersible dual-use explosion-proof drainage equipment, it is necessary to develop a high-voltage land-submersible dual-use flameproof outlet device. similar equipment. Contents of the invention [0003] The object of the present invention is to provide a high-voltage land-submarine dual-purpose explosion-proof outlet device with good sealing performance, wh...
