Embodiment

[0033] Such as figure 1 As shown, the shell 1 adopts the structure of stepped shrinkage, which is convenient for the design and assembly of the shell bushing 9; while the inner cavity of the traditional breakaway valve is a V-shaped structure, it is impossible to realize the PTFE bushing, and even the rubber bushing is difficult. Achieve anastomosis.

[0034] Such as figure 2 and 3 As shown, the disc 2 adopts the structure of internal passage and diversion, and is guided by the outer wall, which solves the problem of blocking the bushing by the center-guided valve stem support seat of the traditional breakaway valve, which is the key to the structural principle of the breakaway valve. The breakthrough makes it simple and easy for the bush to realize the barrier between the medium and the shell.

[0035] Such as Figure 5 As shown, the material of the valve seat 3 is mainly made of tetrafluoroethylene, and the metal is embedded outside, which can not only easily realize se...

Abstract

The invention discloses a fluorine-lined emergency release coupler which comprises a shell, valve clacks and a valve seat, and is characterized in that the valve clacks are sleeved in the shell and are correspondingly connected with the valve seat; lug shafts of an upper valve clack and a lower valve clack adopt a female-male cooperation structure; and the valve seat adopts a combined valve seat,and a main seal is arranged on the valve seat. The shell of the fluorine-lined emergency release coupler disclosed by the invention adopts materials such as metal inner lining fluorine glue or polytetrafluoroethylene and the like, an inner piece material is totally coated with the polytetrafluoroethylene or metal; and the valve has an inner lining structure adapted to the shell, and the valve clacks creatively adopt a split-flow type structure, so that normal flow can be ensured, and effective sealing after separation also can be ensured. The emergency release coupler has a unique structure and has novel principles, and the use is effective; and therefore, the emergency release coupler is an effective breakthrough and innovation on a conventional emergency release coupler.

Description

technical field [0001] The invention belongs to the technical field of breakaway valves, in particular to a fluorine-lined emergency breakaway valve. Background technique [0002] Emergency breakaway valve (emergency disengagement device) can prevent leakage accidents caused by accidental breakage of crane pipes and hoses, applicable fields include ship-to-shore unloading, tank loading and unloading of roads and railways, and other fixed and mobile fluid storage devices, such as crane pipes , the connection between the fluid transfer arm and the transport carrier. [0003] The emergency disengagement system ensures the safety of fluid transportation to the greatest extent in marine and land cranes. Through a simple and unique design, when the crane exceeds the rated capacity of the operating system, this system can be fully automatic and safe disconnection in the crane without any leakage. The advantages are guaranteed triggering in the event of a hazard, instantaneous val...
