Described ball-type impeller is in the inner chamber of valve body, and ball-type impeller is comprised of valve shaft, valve ball, water storehouse;

1, valve ball both sides are connecting respectively valve shaft, and one end of valve shaft is fixed in the bearing on valve body, and the other end of valve shaft is connected with power plant B after extending valve body by bearing;

2, the surface of valve ball and the surface of internal cavity of valve body will carry out surface high frequency quenching, electroplating surface treatment process, then carry out grinding and polishing processing, processing after turnning and milling processing, and valve ball and body cavity are fully fitted.

Described water storehouse is at the inner chamber of valve ball, and water storehouse Hatch Opening is on the surface of valve ball; 1, the quantity of water storehouse is 1-8; 2, water storehouse is bin independently, between water storehouse and water storehouse, does not communicate.

Working principle of the present utility model is: steam drainage ball valve is for the condensed water elimination in steaming plant; Start power plant, power plant drive the work of ball-type vane rotary; Condensed water in steaming plant is entered in water storehouse by the water intake above valve body, and ball-type impeller continues rotation and gets up, and the water outlet of the water storehouse of filling with condensed water below valve body discharged; The empty water storehouse of drained water is along with ball-type impeller continues to rotate to water intake, the water inlet like this going round and beginning again, draining, water inlet, draining ... the utility model compared with prior art has following beneficial effect: steam drainage ball-valve structure is simple, it can directly be discharged into the condensed water in steaming plant numerical control device outside; Automatic steam trap Trap adopts the design of ball-type impeller, and between ball-type impeller and valve body, degree of laminating is good, blanket gas density is high, and in drainage procedure, Steam loss is few, and draining is rapidly convenient; Can adjust according to the job requirement of system, ambient conditions restriction is few, practical, applied range.

Accompanying drawing explanation:

Fig. 1 is the structural representation of the utility model steam drainage ball valve;

Fig. 2 is the cross section view of the valve of the utility model steam drainage ball valve;

Fig. 3 is the ball-type impeller cross section view of the utility model steam drainage ball valve;

Specifically execute mode:

Below in conjunction with drawings and Examples, to model utility is bright, be described further:
