Description
Technical field：
The present invention relates to technical field of metallurgical machinery, specifically a kind of band monitors double containment hydraulic joint device, for closing
The double containment of key hydraulic pipeline join domain is fixed, meanwhile, it can detecte the failure conditions of interior sealing, and in interior seal failure
Replacement in time, meanwhile, also sealing effect can be realized by external seal in the case where interior seal failure, avoid because of seal failure
Caused producing line is shut down, while can accomplish effectively to prevent, and is widely used in the connection of hydraulic system pipeline in metallurgical machinery
Place.
Background technique：
PQF Hot Line shares 16 sets of hydraulic system at present, and control valve platform 116, more than 2000 root of connecting pipe, pipe joint is up to
More than at 30000, and SAE Normal hydraulic bump joint is mostly used to connect greatly high pressure, high flow volume region, SAE flanged joint tool
There is the features such as high pressure resistant, detachable, relative smoothness is high, but there is also biggish defects：By single O-shaped between bump joint
Circle or the single-pieces sealing element such as rectangular loop seal, once the bolt of mounting flange occurs loosening or seal aging, pole
Easily there is biggish leakage, has biggish restriction for the production of successional steel producing line, the leakage of hydraulic oil is also brought
More serious oil product waste, environmental pollution, security risk, and such failure can not examine maintenance by daily point and go to prevent,
In uncontrollable state, single failure handled the time at 0.5-3 hours, larger impact production line production.
Summary of the invention：
The purpose of the present invention is overcoming deficiency present in above-mentioned prior art, and the double containment that provides a kind of monitoring of band is hydraulic connects
Head device mainly solves the Normal hydraulic bump joint connection that existing connecting pipe uses and easily occurs revealing and influencing production
Problem.
The technical scheme is that：A kind of double containment hydraulic joint device of band monitoring, including first flange connector and
Second flange connector, is characterized in that, the first flange connector and second flange connector pass through the first connecting flange
It is fixed together with the second connecting flange with the first fixing bolt and the second fixing bolt, pushes down first flange connector and the second method
Interior sealing and external seal between blue connector；Pressure tap is set on the first flange connector, pressure tap is connected by connecting line
Pressure gauge is realized by pressure tap, connecting line and pressure gauge to pressure in the annular ring formed between bump joint, bump joint
Detection, with the damaged condition sealed in judging, while external seal also may be implemented in the sealing function under the failure conditions of sealing.
Compared with the prior art a kind of double containment hydraulic joint device of band monitoring of the present invention has reality outstanding
Matter feature and marked improvement use double seal between 1, connector, the effect of sealing is made to add one layer of insurance；2, band pressure is examined
It surveys, detects the damaged condition of internal layer sealing ring, play the role of preventible；3, daily inspection can be made full use of to accomplish to dock
The monitoring of head simultaneously makes full use of unproductive downtime to replace internal layer sealing according to monitoring result；4, the piecing devices
Structure is simple, it is easy to use, be easily understood, can be used for more important pressure pipeline connection occasion；5, scene is had using proof
Universal promotional value.
Detailed description of the invention：
Fig. 1 is schematic structural view of the invention；
Fig. 2 is effect picture of the invention.
Specific embodiment：
For a better understanding and implementation, providing specific embodiment with reference to the accompanying drawing, the present invention will be described in detail；Lift implementation
Example for explaining only the invention, is not intended to limit the scope of the present invention.
Embodiment 1, referring to Fig. 1,2, first flange connector 1 and second flange connector 2 pass through the first connecting flange 3 and second
Connecting flange 4 pushes down interior sealing 7 and external seal 8, and the first connecting flange 3 and the second connecting flange 4 lean on 5 He of the first fixing bolt
Second fixing bolt 6 is fixed together, and pressure tap 9 is threadedly attached on first flange connector 1, and pressure tap 9 passes through company
Wiring connects pressure gauge 10, is realized by pressure tap 9, connecting line and pressure gauge 10 to shape between bump joint 1, bump joint 2
At annular ring in pressure detection, with judge in sealing 7 damaged condition, while external seal 8 also may be implemented in sealing 7 mistake
Sealing function in the case of effect；Form a kind of double containment hydraulic joint device of band monitoring of the invention.
The double containment hydraulic joint device of a kind of band monitoring of the present invention, before use, completing the installation of this piecing devices
After, before upper pressure is led in connector, first overbottom pressure and air are drained by connecting line and pressure gauge, pressure gauge index is at this time
0, after leading to upper pressure, normal device action can be carried out, when pressure gauge index is not 0 after a period of work, in explanation
Sealing has damaged, but external seal plays sealing function at this time, and external seal needs to carry out more using daily unproductive downtime
It changes.
