Abstract
The utility model provides a bypass quick-opening valve for a TRT system, which comprises a valve body and a valve shaft, wherein a drive device of the valve is an automatically adjustable electric device; a normally closed type jack electromagnetic clutch is arranged between the valve body and the automatically adjustable electric device; the valve shaft is connected with an output shaft of the automatically adjustable electric device through the normally closed type jack electromagnetic clutch; the tail part of the valve body is provided with a swing arm and a weight dropper; the swing arm is fixedly connected with the valve shaft through a key. The utility model has the advantages that the combined control way of the automatically adjustable electric device and a mechanical device is adopted, the control is simple, the cost is reduced and the performance is stable and reliable.
Description
Affiliated technical field
The utility model relates to a kind of butterfly valve, particularly relates to a kind of bypass quick opening valve that uses in the blast furnace gas excess pressure power generating system.
Background technique
Bypass quick opening valve in the TRT system is used to one of key equipment of protecting blast furnace furnace roof substantial equipment, is the automatic control tegulatingdevice that keeps the normal operation of turbine unit simultaneously.The bypass quick opening valve of existing TRT system adopts hydraulic control, by servo-cylinder, servovalve, hydrovalve platform, servo electric control cubicle, the 4-20mA current signal that receiving system gives, realize the automatic adjusting of valve opening, thereby the pressure of regulating system or flow, location status with valve switch converts the 4-20mA current signal to simultaneously, feeds back to control system and comes, and realizes the automatic adjusting of valve and opens fast.Control is complicated, cost is high, and its performance is subjected to the influence in system dynamic source and becomes unstable.
Summary of the invention
The bypass quick opening valve control of existing TRT system is complicated, cost is high, the deficiency of unstable properties in order to overcome, and the utility model provides a kind of TRT system bypass quick opening valve that adopts automatic adjustment type Denso.
The technological scheme that its technical problem that solves the utility model adopts is an a kind of TRT system bypass quick opening valve, comprise valve body, valve shaft, the drive unit of valve is automatic adjustment type Denso, between valve body and the automatic adjustment type Denso Normally closed type tooth embedding magnetic clutch is housed also, valve shaft connects by Normally closed type tooth embedding magnetic clutch with the output shaft of automatic adjustment type Denso, the afterbody of valve body is equipped with swing arm, weight, and swing arm is fixedlyed connected by key with valve shaft.
The beneficial effects of the utility model are the modes that adopted automatic adjustment type Denso and mechanical device to jointly control, and control simply, greatly reduce cost and stable and reliable for performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 embodiment's structural drawing.
Among the figure: 1. automatic adjustment type Denso; 2. Normally closed type tooth embedding magnetic clutch; 3. valve body; 4. valve shaft; 5. swing arm; 6. weight.
Embodiment
As shown in Figure 1, a kind of TRT system bypass quick opening valve, comprise valve body 3, valve shaft 4, the drive unit of valve is automatic adjustment type Denso 1, between valve body 3 and the automatic adjustment type Denso 1 Normally closed type tooth embedding magnetic clutch 2 is housed also, valve shaft 4 connects by Normally closed type tooth embedding magnetic clutch 2 with the automatic output shaft of adjustment type Denso 1, and the afterbody of valve body 3 is equipped with swing arm 5, weight 6, and swing arm 5 and valve shaft 4 are fixedlyed connected by key.Valve is by the 4-20mA signal of receiving system, the flow of regulating system and pressure when nominal situation.Valve is in opening state, and weight lifts.In the time of need opening fast when having an accident, Normally closed type tooth embedding magnetic clutch 2 dead electricity, automatically the output shaft and the valve shaft 4 of adjustment type Denso 1 are in disengaged condition, valve can be opened under the effect of swing arm weight-driven potential energy fast, adjusts the time of opening soon by the weight of adjusting weight 7 and the length of swing arm 6.
