Embodiment 1

[0038] This technical solution only provides a sealed integrated structure, and the used pipe flange 1, flange pre-tightening stud 2 and flange pre-tightening bolt and nut 4 are only used to assist in explaining the accessories used in this technical solution, and should not be limited.

[0039] The first aspect of the present invention is to provide a flange static seal low-emission system integration device, including pipe flanges 1 and flange pre-tightening studs 2 arranged symmetrically up and down, and the flange pre-tightening studs 2 are pierced On the symmetrically arranged pipe flange 1, flange pre-tightening bolts and nuts 4 are installed at the upper and lower ends of the flange pre-tightening stud 2; it also includes: flange live pressure gasket 3, flange bolt Pre-tightening disc spring 6 and flange bolt pre-tightening force fixed value facility 5, the flange live pressure gasket 3 is installed between the symmetrically arranged pipe flanges 1, and the flange bolt p...

Embodiment 2

[0075] Based on the implementation of embodiment 1,

[0076] Further, the quantity of the flange bolt pretension disc spring 6 is two pieces, which are respectively installed between the flange pretension bolt nut 4 on the upper part and the pipe flange 1 and the flange pretension bolt nut 4 on the lower part and the pipe flange 1 respectively. between flange 1.

[0077] In this embodiment, there are two flange bolt pretension disc springs 6, which are installed between the flange pretension bolt nut 4 on the upper part and the pipe flange 1 and between the flange pretension bolt nut 4 on the lower part and the pipe flange 1. Between, up and down at the same time maintain a relatively stable bolt pre-tightening force.

Abstract

The invention discloses a flange static seal low-dissipation system integration device and seal mounting process. The device comprises pipe flanges, flange pre-tightening studs, and flange pre-tightening bolt nuts, and further comprises flange movable pressing gaskets, flange bolt pre-tightening disc springs and flange bolt pre-tightening force fixed-value facilities, wherein the flange movable pressing gasket is arranged between the symmetrically-arranged pipe flanges; the flange bolt pre-tightening disc spring is located between the flange pre-tightening bolt nut and the pipe flange; and theflange bolt pre-tightening force fixed-value facility is arranged on the flange pre-tightening stud. The low-dissipation system integration device is composed of three parts; the flange movable pressing gasket technology can comprehensively replace a non-metal gasket, a metal winding gasket, a wave tooth composite gasket, a metal coating gasket and the like; the flange bolt pre-tightening disc springs can solve the problem that the bolt pre-tightening force of the flange pre-tightening bolt nuts is lost due to temperature difference, pressure difference, vibration and the like, and maintain the relatively stable bolt pre-tightening force; and fixed-value anti-blocking lubricating grease is beneficial to high-temperature meshing prevention and low-temperature freezing corrosion preventionof bolts and nuts.

Description

technical field [0001] The application relates to the technical field of low-emission sealing installation, in particular, to a flange static sealing low-emission system integration device and a sealing installation process. Background technique [0002] The static seal integration of the equipment flange is mainly composed of pipe flanges, flange pre-tightening bolts and nuts and metal gaskets. The mutual pre-tightening installation is used to achieve flange mechanical sealing. Among them, the flange pre-tightening bolts and nuts are often due to The temperature difference, pressure difference, vibration and other reasons lead to the loss of the bolt pre-tightening force, and the relatively stable bolt pre-tightening force cannot be maintained. Therefore, it is no longer possible to form a sealed installation with the pipe flange and the flange pre-tightening bolts and nuts. [0003] The flange static seal of the equipment is affected by factors such as internal medium temp...
