Abstract
The utility model relates to a connecting pipe, and particularly to an explosion-proof flexible connecting pipe. The explosion-proof flexible connecting pipe comprises a connecting flexible pipe and connectors at two ends of the connecting flexible pipe. A compression sleeve is arranged outside each of two connection parts between the connecting flexible pipe and the connectors. According to the explosion-proof flexible connecting pipe, the connection parts between the connectors and the connecting flexible pipe are provided with the compression sleeves additionally, thereby greatly improving connecting strength between the flexible pipe and the connectors, improving connection reliability between the flexile pipe and the connectors, and prolonging service life of the connecting pipe.
Description
Technical field
The utility model relates to a kind of tube connector, relates in particular to a kind of explosion-proof flexible connection pipe.
Background technology
Explosion-proof flexible connection pipe has been applicable to damp or mixture place, line or steel pipe wiring as explosion-proof electric equipment are crooked, the place larger as the crooked difficulty of wiring connects used, the connecting bolt that existing explosion-proof tube connector two ends mostly are flexible pipe and two ends is directly connected, when pressure greatly 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, threatens the safe handling of equipment, also can cause casualties and tremendous economic loss when serious.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and provides a kind of and is connected firmly, long service life, safe and reliable explosion-proof flexible connection pipe.
The technical scheme that realizes the utility model object is: a kind of explosion-proof flexible connection pipe, comprises connecting hose and the connector that is 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, 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.
Adopt after technique scheme, the utlity model has following positive effect:
(1) the utility model connector and connecting hose junction have additional clamping sleeve, can increase substantially the bonding strength of flexible pipe and connector, have improved the reliability that both connect, thus the useful life of improving tube connector;
(2) the utility model protective sleeve adopts stainless steel braided steel wire to form, not only there is good amount of deflection, and there is excellent corrosion resistance and fire protecting performance, thereby avoided under rubber protecting jacket low temperature flexibility little, easily the defect of aging and weathering, improves its useful life;
(3) zinc coat that the utility model connector outside is provided with can improve the corrosion resistance on connector surface, thereby makes it be applicable to various operational environments;
(4) screw thread in the utility model tube connector length, internal diameter and two ends connector can be adjusted as required, meets client's diversified demand.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the utility model structural representation;
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 utility model has connecting hose 1 and is positioned at the connector 2 at connecting hose 1 two ends; Connecting hose 1 is also provided with clamping sleeve 3 with connector 2 outsides, junction, has further guaranteed the reliability that be connected of connecting hose 1 with connector 2, has fully guaranteed the safety of equipment.
As preferred version of the present utility model, 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 of metal hose 12 outsides 11 adopts stainless steel wires braiding to form, and can meet tube connector and have larger amount of deflection, also has anti-agingly, and corrosion resistant performance, can increase substantially useful life of tube connector.
The utility model connecting hose 1 one end connector 2 comprises the first attaching nut 21 and female adapter 22, and described inner bolt joint 22 inside are provided with internal thread; Other end connector 2 comprises the second attaching nut 23 and male connection 24, and described male connection 24 outsides are provided with external screw thread, for being connected of other antiknock devices.
The utility model tube connector length L 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 surfaces are also provided with zinc coat, and zinc coat not only has good corrosion resistance, and can make connector surface more attractive in appearance.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
