Embodiment Construction

[0039] The nuclear safety valve provided by the present invention is composed of an auxiliary valve, a main valve, a relay valve, No. 1 and No. 2 electromagnetic release valves, a filter, a pulse tube and the like. The way it is composed is as follows: figure 1 As shown, the relay valve, the main valve and the auxiliary valve adopt an upper, middle and lower connected structure; another way of composition is: as Figure 6 As shown, the relay valve and the main valve are connected up and down, and the auxiliary valve is arranged beside the main valve, and the axis lines of each axis are perpendicular to the horizontal plane. The structure of the main valve is as figure 1 As shown, the main valve seat [31] and the main isolation valve seat [32] are screwed in the main valve body [30] from bottom to top in a threaded manner, the main valve seat [31], the main isolation valve seat [32] ] The annular space formed is connected with the pulse tube [29]. The main valve disc [33] is...

Abstract

A high-safety valve for nuclear power unit is composed of three functional modules: safety release, fast isolation and forced opening or closing. It has a primary valve and a secondary valve. When external valve flap is closed, the safety release and secondary valve can be cut off at the same time. Its advatnages are small size, light weight, high reliability and long service life.

Description

1. Technical field [0001] The present invention relates to a safety valve, especially a nuclear safety valve. [0002] The safety valve is an essential overpressure protection device for all pressure vessels or systems with variable pressure media inside. [0003] There are two types of existing safety valves: direct acting safety valves and indirect acting safety valves. In terms of function, it is divided into safety function, isolation function and release function. [0004] The nuclear safety valve provided by the invention belongs to the indirect acting safety valve, which has safety functions, isolation functions and release functions, and is a multifunctional safety valve. It is mainly used in nuclear overpressure protection systems. [0005] Because the nuclear safety valve provided by the present invention has an isolation mechanism inside, when the safety mechanism is opened to discharge the pressure medium, the main isolation disc in the isolation mechanism can a...
