Embodiment Construction

[0022] Such as Figure 1-Figure 5 A dual-drive flushing valve shown includes a valve body 1, a valve disc 2, a valve shaft 3 for driving the valve disc 2, and a valve shaft driving mechanism 4 linked with the valve shaft 3. There are openings on both sides of the valve body 1 11. Between the two openings 11, there is a connection chamber 12 connecting the two openings 11. One of the openings 11 of the valve body 1 is provided with a valve seat 5, and the valve disc 2 is placed at the opening 11 of the valve body 1 provided with the valve seat 5, and the valve shaft 3 cooperates with the valve shaft driving mechanism 4 to form the two sides of the valve body 1. The conduction or closure of the opening 11. The valve disc 2 includes a movable end 21 and a swing end 22, the swing end 22 is linked with the valve shaft 3 through the swing member 6, and the movable end 21 is provided with a locking mechanism 7 that conflicts with or disengages from this end; the valve disc 2 A seal...

Abstract

The invention relates to a pipe flushing device, in particular to a dual-drive pipe flushing valve for flushing an assembled pipe for nuclear power engineering. The technical scheme is as follows: the dual-drive pipe flushing valve comprises a valve body, a valve clack, a valve shaft for driving the valve clack, and a valve shaft drive mechanism linked with the valve shaft, wherein, two sides of the valve body are equipped with openings; a connection cavity for communicating the two openings is arranged between the two openings; one of the openings of the valve body is equipped with a valve seat; the valve clack is arranged at the opening equipped with the valve seat on the valve body and is matched with the valve shaft drive mechanism through the valve shaft to conduct or close the two openings of the valve body; the valve clack comprises a movable end and a swinging end, the swinging end is linked with the valve shaft via a swinging part, and the movable end is equipped with a locking mechanism in propping or separation fit with the movable end; and a seal assembly is arranged between the valve clack and the valve seat. By adopting the technical scheme, the dual-drive pipe flushing valve has the advantages of good tightness, compact structure and no need of manual cyclic operation.

Description

technical field [0001] The invention relates to a pipeline flushing device, in particular to a dual-drive pipe flushing valve used for flushing after installation of nuclear power engineering pipelines. Background technique [0002] After the nuclear power engineering pipeline is installed, it is necessary to wash away the welding slag, welding beans or iron filings and other debris left in the pipeline during the construction process. [0003] At present, when flushing pipes in early nuclear power projects, the pressure plate bolts are used to block the pipe outlet. When the compressor charges the pipeline pressure to 0.6MPa, personnel pull the pressure plate away with a rope tens of meters away to complete a flushing. Then, return to the site to tie the rope and wait for the boost again. Repeatedly, it takes about 200 cycles to complete flushing. Because the pressure plate is prone to leakage, it is necessary to adjust and tighten the bolts several times every time a flu...
