[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of electric liquid interlock fire-proof emergency cut-off ball valve, has good airproof performance, and is safe and reliable, be active in one's movements, keying speed is fast, long service life, be not subjected to externally temperature influence, cost is low, safeguards characteristics simply and easily.
For achieving the above object, the utility model proposes a kind of electric liquid interlock fire-proof emergency cut-off ball valve, comprise ball valve element, connect support, fireproof box, actuator, screw, flat key, valve rod and supporting frame, fixedly connected with screw by connecting support between described ball valve element and the actuator, pass through the valve rod transmission joint between ball valve element and the actuator; Described actuator is installed in the fireproof box, and supporting frame is installed in the inboard of fireproof box, and actuator is fixed by supporting frame; Described valve rod cooperates installation with actuator by flat key.
As preferably, described electric liquid interlock fire-proof emergency cut-off ball valve also comprises fireproof seal gum, and fireproof seal gum is arranged between valve rod and the actuator, prevents that flame from entering, and influences actuator.
As preferably, described actuator is mechanical-electrical-hydraulic integration single-acting actuator, realize that fast shut-off control resets fast with failure safe, final controlling element generally is divided into two kinds of single-acting and double-actions, double-action inside does not have spring, there is spring single-acting inside, and when fault (such as when outage), single-acting can realize actuator's action by inner spring force.
As preferably, described electric liquid interlock fire-proof emergency cut-off ball valve comprises that also control detects safety door, and control detects safety door and is installed on the fireproof box, makes simple to operation.
The beneficial effects of the utility model: the utility model drives valve by the intelligent mechanical-electrical-hydraulic integration single-acting of employing actuator; actuator's integral body is included in the good fireproof box of sealing; protection actuator is not damaged in the short time in fire hazard environment; thereby realize that valve automatic fast shut-off control under fire condition resets fast with failure safe; intercommunication in the device of cut-out petrochemical industry tank field between jar and the jar; reduce the fire area; the accident that prevents enlarges; reduce economic loss, have huge social benefit and economic benefit.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
