Abstract
The utility model relates to a valve, in particular to a high-temperature and high-pressure stop valve of a T-type power station, which comprises a valve clack, a valve stem and a packing box, wherein one end of the valve stem is connected with the valve clack. The valve also comprises a valve body forged by high-temperature alloy steel, wherein the valve clack and the packing box are arranged in the valve body, and the other end of the valve stem is connected with a hand wheel; and one end of the valve stem is arranged in the valve clack, and a ball bearing is arranged at a connecting part of the valve stem and the valve clack. In the structure, the connecting part of the valve stem and the valve clack adopts the ball bearing design, accordingly, even if the medium is suddenly enlarged, the locking phenomenon of the valve stem and the valve clack does not occur; the valve is forged by the high-temperature alloy steel, so that the problem that blisters of the valve body are loosened can not occur, thereby improving the service life of the valve.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of T type power station high temperature and high pressure cut-off valve.
Background technique
The open-shut device of stop valve is the flap of stopper, and sealing surface is the plane or the conical surface, the center line moving linearly of flap longshore current body.The forms of motion of valve rod also has lifting rotation rod-type, and stop valve is meant the valve that closure member moves along the valve seat center line.According to this mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio.Because the valve rod of such valve is opened or shutoff stroke is shorter relatively, and have and cut off function very reliably, again because the variation of valve seat port and the stroke relation in direct ratio of flap are very suitable for the adjusting to flow.Therefore, such valve is suitable as cut-out or adjusting and throttling usefulness very much.
Be applied to the stop valve in the system that dredges, discharges water in thermal power plant, sealing surface leaks easily, and medium increases suddenly can produce the phenomenon of locking, and working life is not long.
Summary of the invention
The utility model provides a kind of good airproof performance, the T type power station high temperature and high pressure cut-off valve of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of T type power station high temperature and high pressure cut-off valve, comprise flap, valve rod, Stuffing box, one end of valve rod is connected with flap, it is characterized in that also comprising that high-temperature alloy steel forges the valve body that forms, flap and Stuffing box are arranged in the valve body, the other end of valve rod is connected with handwheel, and an end of valve rod is set in the flap, is provided with ball at the joint of valve rod and flap.
This joint that is arranged on valve rod and flap has adopted the design of ball type, even medium increases the phenomenon that valve rod and flap locking also can not occur suddenly, and the valve body that valve body adopts the high-temperature alloy steel forging to form makes valve body not have problems such as trachoma is loose, the life-span of having improved valve.
Of the present utility modelly further be set to: the joint surface between valve rod and the Stuffing box is provided with overlay cladding.
This is arranged between the stem packing case and is provided with overlay cladding, has reduced abrasion condition, increases its sealability, avoids leaking.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
Embodiment
With reference to figure 1 as can be known, a kind of T type of the utility model power station high temperature and high pressure cut-off valve, comprise flap 2, valve rod 3, Stuffing box 4, one end of valve rod 3 is connected with flap 2, and valve body 1 is forged by high-temperature alloy steel and forms, and flap 2 and Stuffing box 3 are arranged in the valve body 1, the other end of valve rod 3 is connected with handwheel 5, one end of valve rod 3 is set in the flap 2, is provided with ball 6 at the joint of valve rod 3 and flap 2, and the joint surface between valve rod 3 and the Stuffing box 4 is provided with overlay cladding.
Claims (2)
1. T type power station high temperature and high pressure cut-off valve, comprise flap, valve rod, Stuffing box, one end of valve rod is connected with flap, it is characterized in that: comprise that also high-temperature alloy steel forges the valve body that forms, flap and Stuffing box are arranged in the valve body, the other end of valve rod is connected with handwheel, and an end of valve rod is set in the flap, is provided with ball at the joint of valve rod and flap.
