Part composition；Wherein, the sphere is placed in the main valve body, and left side is arranged valve seat, on the left of the valve seat by disc spring with
The main valve body forms axial floating connection, and right side is extended internally sealing by the auxiliary valve body, outside the auxiliary valve body extension
There are gaps with main valve body inner wall for wall, are sealed by octagonal seal washer, and the auxiliary valve body is fixed on the right side of main valve body, the bracket
It is connect by connector sleeve with main valve body, which is characterized in that the transmission device is connect by axle sleeve with valve rod.
Preferably, in a kind of above-mentioned power station drain valve, the valve seat of the sphere face and cooperation sealing, the pair
Valve body extended spot sealing surface sprays chromium carbide material, and one-to-one matching is taken to grind.
Preferably, in a kind of above-mentioned power station drain valve, multiple groups are arranged in the positioning sleeve, are connected using soket head cap screw
It connects.
It can be seen via above technical scheme that compared with prior art, the utility model provides a kind of power station drain valve, pass
Dynamic device is connect by axle sleeve with valve rod, and the wear rate of transmission shaft and valve rod is reduced, and is replaced conveniently, easy to maintain；Sphere table
Face and matched valve seat, auxiliary valve body extend contact surface and one-to-one matching are taken to grind, and sealing grade can achieve VI grade,
Each contact surface (including outer surface of spheroid) sprays chromium carbide material, and the performance of Wear-resistant, high-temperature resistant gets a promotion, and service life obtains
To promotion；Using multiple groups positioning sleeve, positioning accuracy is higher, more acurrate.
