The working principle of the scheme is as follows:

when pressure relief is needed, the first low-temperature stop valve is closed, and the second low-temperature stop valve is opened to discharge gas or liquid to reduce pressure; when the pressure is not required to be relieved, the first low-temperature stop valve is opened, and the second low-temperature stop valve is closed. When the user pipeline exceeds the limited pressure of the adjustable safety valve, the adjustable safety valve automatically opens for pressure relief; when the fully adjustable safety valve needs to be overhauled or verified, the first low-temperature stop valve is closed, and the adjustable safety valve is detached; insert the bolt when judging user's pipeline transportation and be gaseous, adjustable relief valve becomes the formula relief valve that opens a little, extracts the bolt when the transportation is liquid, and adjustable relief valve becomes the formula relief valve that opens a wide margin.

In a further aspect, the tee has an outlet connected to a bleed line.

And the gas discharged by the adjustable safety valve and the second low-temperature stop valve is discharged through a discharge pipeline.

In a further aspect, the three-way ferrule has an inlet that connects with a user line.

In the use process of a user, the stability of the system is guaranteed by manual pressure relief when the monitored system pressure is abnormally overloaded and the like, but the safety valve can be adjusted to provide final safety guarantee when pressure relief is not performed in time.

The utility model has the advantages that:

the device has the advantages of convenient installation, no need of welding, no need of X-ray flaw detection treatment and convenient disassembly during maintenance.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in fig. 1-3, a safety discharge integrated system comprises an adjustable safety valve 2, a first low-temperature stop valve 5, a second low-temperature stop valve 7, a three-way cutting sleeve 6, a double-head cutting sleeve 10 and a three-way pipe 9, wherein an inlet of the adjustable safety valve 2 is connected with an outlet of the first low-temperature stop valve 5 through a first double-head bending cutting sleeve 4, an inlet of the first low-temperature stop valve 5 and an inlet of the second low-temperature stop valve 7 are respectively connected with two outlets of the three-way cutting sleeve 6, an outlet of the second low-temperature stop valve 7 is connected with one inlet of the three-way pipe 9 through a second double-head bending cutting sleeve 8, the other inlet of the three-way pipe 9 is connected with an outlet of the adjustable safety valve 2 through the double-head cutting sleeve 10, a piston rod 12 is arranged inside the adjustable safety valve 2, a spring 11 is sleeved on the piston, and sealing rings 13 are arranged inside the nuts 3 on the three-way clamping sleeve 6, the double-head clamping sleeve 10, the first double-head bending clamping sleeve 4 and the second double-head bending clamping sleeve 8.
