Abstract
The invention relates to a connecting pipe, in particular to an explosion-proof flexible connecting pipe. The explosion-proof flexible connecting pipe comprises a connecting hose and connectors at the two ends of the connecting hose, and compacting sleeves are arranged outside the connecting parts between the connecting hose and the connectors. As the compacting sleeves are additionally arranged at the connecting parts between the connectors and the connecting hose, the bonding strength of the hose and the connectors is greatly improved, the mutual connecting reliability is improved, and accordingly, the service life of the connecting pipe is prolonged.
Description
Technical field
The present invention relates to a kind of tube connector, particularly relate to a kind of explosion-proof flexible connection pipe.
Background technology
Explosion-proof flexible connection pipe has been applicable to damp or mixture place, as the line of explosion-proof electric equipment or steel pipe wiring bending, the place larger as the bending difficulty of wiring connects used, existing explosion-proof tube connector two ends mostly are flexible pipe and are directly connected with the connecting bolt at two ends, when pressure is large or service time is longer, flexible pipe easily comes off from connecting bolt, affects the normal use of equipment.Existing flexible pipe outer protection cover mostly is elastomeric material and makes in addition, and under rubber hose low temperature, flexibility is little, and easily aging, and useful life is low, and easy firing, threaten the safe handling of equipment, also can cause casualties time serious and tremendous economic loss.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide one to be connected firmly, long service life, safe and reliable explosion-proof flexible connection pipe.
The technical scheme realizing the object of the invention is: a kind of explosion-proof flexible connection pipe, comprises connecting hose and the connector being positioned at connecting hose two ends; Described connecting hose and outside, connector junction are also provided with clamping sleeve.
Technique scheme, described connecting hose comprises outside protective sleeve and is positioned at the metal hose of protective sleeve inside.
Technique scheme, described connecting hose one end connector comprises the first attaching nut and female adapter, and described inner bolt joint inside is provided with internal thread; Other end connector comprises the second attaching nut and male connection, and described male connection outside is provided with external screw thread.
Technique scheme, the protective sleeve of described metal hose outside is stainless steel wire woven protective cover.
Technique scheme, described tube connector length L is 700 ~ 1200mm.
Technique scheme, described connecting hose internal diameter is 13 ~ 51mm.
Technique scheme, described connector outer surface is provided with zinc coat.
After adopting technique scheme, the present invention has following positive effect:
(1) connector of the present invention and connecting hose junction have additional clamping sleeve, can increase substantially the bonding strength of flexible pipe and connector, improve the reliability that both connect, thus improve the useful life of tube connector;
(2) protective sleeve of the present invention adopts stainless steel braided steel wire to form, and not only has good amount of deflection, and has excellent corrosion resistance and fire protecting performance, thus under avoiding rubber protecting jacket low temperature, flexibility is little, and the defect of easily aging and weathering, improves its useful life;
(3) zinc coat that connector outside of the present invention is provided with can improve the corrosion resistance on connector surface, thus makes it be applicable to various operational environment;
(4) screw thread in tube connector length of the present invention, internal diameter and two ends connector can adjust as required, meets the diversified demand of client.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention;
In figure 1, connecting hose; 11, protective sleeve; 12, metal hose; 2, connector; 21, the first attaching nut; 22, female adapter; 23, the second attaching nut; 24, male connection; 3, clamping sleeve.
Embodiment
(embodiment 1)
See Fig. 1, the explosion-proof flexible connection pipe of the present invention has connecting hose 1 and is positioned at the connector 2 at connecting hose 1 two ends; Connecting hose 1 and outside, connector 2 junction are also provided with clamping sleeve 3, further ensure connecting hose 1 and the reliability of the connection of connector 2, fully ensure that the safety of equipment.
As preferred version of the present invention, connecting hose 1 comprises outside protective sleeve 11 and is positioned at the metal hose 12 of protective sleeve 11 inside.Preferably, the protective sleeve 11 of metal hose 12 outside adopts stainless steel wire to weave and forms, can meet tube connector and have larger amount of deflection, also have anti-aging, corrosion resistant performance, can increase substantially the useful life of tube connector.
Connecting hose 1 one end of the present invention connector 2 comprises the first attaching nut 21 and female adapter 22, and described inner bolt joint 22 inside is provided with internal thread; Other end connector 2 comprises the second attaching nut 23 and male connection 24, and described male connection 24 outside is provided with external screw thread, for the connection with other antiknock devices.
Tube connector length L of the present invention can be designed to 700 ~ 1200mm according to client's actual demand, and connecting hose 1 internal diameter is between 13 ~ 51mm.
Preferably, in order to improve the corrosion resistance on connector surface, connector 2 outer surface is also provided with zinc coat, and zinc coat not only has good corrosion resistance, and connector surface can be made more attractive in appearance.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
