Industry maintaining method, the band water for branch pipe isolating valve, safeguards that branch pipe, which is set, to be connected between total pipeline and equipment, and branch pipe isolating valve, is set
Put on branch pipe, comprise the following steps：
The first pipe joint and the first relief tube are installed in running water drilling on branch pipe between branch pipe isolating valve, and total pipeline,
First pressure table and the first relief valve are set on the first relief tube；
The second pipe joint, the second relief tube are installed in running water drilling on branch pipe between branch pipe isolating valve, and equipment, the
Second pressure table and the second relief valve are set on two relief tubes；
According to the normal temperature bearing capacity of branch pipe material therefor and freezing bearing capacity, the first relief valve of adjustment and the second pressure release
The pressure release value of valve；
To installing refrigerating plant on the branch pipe between the first relief tube and the second relief tube, examination freezing is carried out, is gradually blocked
The current of branch pipe, and the pressure value of first pressure table and second pressure table in refrigerating process is monitored, until frost cutout completely；
Branch pipe isolating valve, and equipment are safeguarded or changed, the first relief tube is then removed and the second relief tube is gone forward side by side
The closure of the pipe joint of row first and the second pipe joint；
Refrigerating plant is released, is normally worked after after branch pipe defrosting.
In a preferred embodiment of the present invention, the end of first relief tube is provided with the first header tank.
In a preferred embodiment of the present invention, the end of second relief tube is provided with the second header tank.
In a preferred embodiment of the present invention, first pipe joint connection be arranged on branch pipe and the first relief tube it
Between.
In a preferred embodiment of the present invention, second pipe joint connection be arranged on branch pipe and the second relief tube it
Between.
The beneficial effects of the invention are as follows：A kind of water equipment living water operation maintaining method that the present invention is pointed out, branch pipe every
Can quickly it be safeguarded during disconnected defective valve, operating efficiency is high, without closing total pipeline, it is ensured that the use water of other equipment, keeps away
Exempt from bursting by freezing or the explosion problem of branch pipe, reduce the urgent prediction scheme measure that bursting by freezing or explosion problem of the enterprise to branch pipe are used
And the manpower and materials spent are put into, security is higher, enterprise is obtained preferable effect in the case where spending seldom fund
Really.
