Embodiment Construction

[0031] Such as figure 1 , figure 2 The schematic diagram of the main structure and working principle of the explosion-driven quick-opening valve is shown.

[0032] Including the main structural unit of the valve, the positioning unit and the explosion driving unit;

[0033] The main structural unit of the valve includes gate plate 4, two left and right limit baffles 5, multiple bolts 6, outer pipe flange 7, inner pipe flange 15, valve base 8, anti-rebound device 12 and two front and rear limit plates. pad 16;

[0034] The two limit baffles 5 on the left and right are respectively fixed on the upper ends of the outer pipeline flange 7 and the inner pipeline flange 15 and protrude inward to form a step; the gate plate 4 is located between the outer pipeline flange 7 and the inner pipeline flange 15, and It is located in the channel formed by the left and right limit baffles 5 and the front and rear two limit pads 16, and can only move up and down; the inner surface of the in...

Abstract

The invention relates to a quick opening door for explosive driving. By using a structure that an explosive driving gate is combined with double sealing rings and the gate is prevented from being sheared by the sealing rings in the opening process, quick opening and communicating of a sealing pipeline and other cavities can be realized, the shortest time is less than 5 ms; the sealing effect is that the leakage rate is smaller than 1*10<-8> Pa.m<3> / s. The technical problem that an existing mechanical opening valve is long in opening time under emergency conditions is solved.

Description

technical field [0001] The invention belongs to the technical field of quick-opening valve development for pipelines, and in particular relates to a quick-opening valve development technology that satisfies the quick opening and effective sealing of some dangerous medium transmission pipelines. Background technique [0002] When some media are involved in an emergency during transmission or storage, such as local combustion and deflagration of flammable media, the internal pressure of the pipeline rises sharply, and the media transmission channel must be quickly opened and safely relieved to prevent a larger equivalent explosion. the occurrence of the event. The inner diameter of common pipes is Φ20-50mm, the opening time is required to be on the order of a few milliseconds, and the sealing degree is required to reach 1×10 -8 Pa·m 3 / s or more, it is difficult to achieve using the traditional mechanical opening method. Contents of the invention [0003] In order to solv...
