Abstract
The invention provides an ash-discharging ball valve which comprises a driving mechanism, an actuating mechanism, a valve body, a valve rod, a valve base and a ball body, wherein the valve body is internally provided with a through flow channel; the middle of the flow channel is provided with a ball-shaped cavity, and the ball body is arranged in the cavity, and one side of the ball body and the valve base form a dynamic seal pair; a through air inlet is formed in a position on the valve body, corresponding to the ball body, one end of the air inlet is communicated with the exterior of the valve body, and the other end of the air inlet is communicated with the cavity in the valve body; and the driving mechanism adopts one out of air-operated, hydraulic drive, motor-driven or gear worm driving ways. The ash-discharging ball valve provided by the invention has the beneficial effects that since the technical scheme is adopted, the ash-discharging valve can adopt multiple driving ways, and the requirements of different occasions are met.
Description
Technical field
The invention belongs to the ball valve field, especially relate to a kind of Unloading ball valve with multiple driving mode.
Background technique
The ball valve of using in Iron And Steel Plant and cinder of electric power plant system owing to being subject to the erosive wear of high temperature slurries and particulate matter, has seriously influenced its working life.
Common Unloading ball valve after repeatedly opening and closing ash discharge, the valve pocket inner accumulated particulate matters such as a large amount of coal ash powders, and form fouling at spherome surface.Since the valve pocket no particulate matter gather fouling with sphere, increased the friction of particulate matter and spheroid, cause spheroid to rotate ineffective and jam phenomenon, even cause the imprecision that cooperates of valve seal pair and spherome surface.
Spheroid rotates ineffective and the jam phenomenon can cause ball valve sealing surface in the switching process prolonged by the flushing time of high temperature slurries or particulate matter, affects the working life of ball valve.Sealing pair directly causes seal leakage with the imprecision that cooperates of spherome surface, causes spheroid and sealing pair to scrap, and causes system normally not move.And the driving mode of existing Unloading ball valve is single, can not satisfy the needs of different occasions.
Summary of the invention
The problem to be solved in the present invention provides a kind of Unloading ball valve, especially has the Unloading ball valve of multiple driving mode.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Unloading ball valve, comprise driving mechanism, actuator, valve body, valve rod, valve seat, spheroid, offer the runner of perforation in the valve body, it is spherical cavity in the centre of runner, spheroid is arranged on this cavity place, it is secondary that one side of spheroid and valve seat consist of motive sealing, corresponding spheroid position offers the inlet hole of perforation on valve body, inlet hole one end is communicated with valve body is outside, cavity in the other end and the valve body is communicated with, and described driving mechanism employing is pneumatic, surge, a kind of in the electronic or worm and gear driving mode.
Further, the aperture of described inlet hole is 6-8cm.
Further, the aperture of described inlet hole is 7cm.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, unloading valve can adopt multiple driving mode, satisfies the needs of various different occasions.

Embodiment
As shown in Figure 1, 2, the invention provides a kind of Unloading ball valve, comprise driving mechanism 1, actuator, valve body 2, valve rod, valve seat, spheroid, offer the runner of perforation in the valve body, it is spherical cavity in the centre of runner, spheroid is arranged on this cavity place, it is secondary that one side of spheroid and valve seat consist of motive sealing, corresponding spheroid position offers the inlet hole 3 of perforation on valve body, inlet hole 3 one ends are communicated with valve body is outside, cavity in the other end and the valve body is communicated with, and described driving mechanism 1 employing is pneumatic, surge, a kind of in the electronic or worm and gear driving mode.
Further, the aperture of described inlet hole is 6-8cm.
Further, the aperture of described inlet hole is 7cm.
The present invention is by offering inlet hole 3 at valve body, gas can be blown from the spherome surface of inlet hole 3 facing to spheroid, to blow off in the fouling that spherome surface forms, reduce and even avoid friction between spheroid and valve body 2 inwalls, make valve working more reliable, indirectly improved the working life of valve.That the present invention adopts is pneumatic, surge, a kind of in the electronic or worm and gear driving mode, can satisfy the needs of various different occasions.
Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
