Abstract
The utility model relates to a valve, in particular to a Y-type power station high temperature high voltage stop valve, which comprises a valve clack, a valve rod and a valve body, wherein one end of the valve rod is connected with the valve clack, the valve clack is arranged in the valve body, the other end of the valve rod is connected with a hand wheel, a middle cavity of the valve body and a channel hole of the valve body are arranged in an inclined plane, and a sealing surface of the valve body and the channel hole are sealed in an inclined plane. The middle cavity of the valve is arranged on an inclined direction, the sealing surface and the channel hole are sealed in an inclined angle, and the structure reduces the corroded strength of the sealing surface of the valve, and prolongs the life of the valve. Because the middle cavity is obliquely arranged, an inlet and an outlet of a channel are close in a level position, thereby effectively reducing the flow resistance of medium, and reducing the noise.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of Y 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, the linear medium flow resistance is big, and noise is big, and the sealing surface between flap and the valve body is washed away by medium, can corrode sealing surface, has shortened the life-span that valve uses.
Summary of the invention
The utility model provides a kind of medium flow resistance little, and noise is little, the Y 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 Y type power station high temperature and high pressure cut-off valve, comprise flap, valve rod, valve body, one end of valve rod is connected with flap, flap is arranged in the valve body, the other end of valve rod is connected with handwheel, it is characterized in that the lumen of valve body and the runner hole of valve body are the plane of inclination setting, the sealing surface of valve body and runner hole are the oblique angle sealing.
This is provided with is arranged to true dip direction with the lumen of valve, sealing surface and runner hole are the oblique angle sealing, such structure reduces the corrosion strength that valve sealing face is subjected to, prolong the life-span of valve, because the inclination of lumen, the import of runner and outlet are close on horizontal position, and effective flow resistance that must reduce medium has reduced noise.
Of the present utility modelly further be set to: the runner hole of lumen and valve body is miter angle and is obliquely installed.
The angle in lumen and runner hole can be other angle in this is provided with, why select 45 degree to be because, angle setting like this makes the import of runner and outlet substantially on same straight line, reduces flow resistance, the effect of reduction noise is best.
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 Y type of the utility model power station high temperature and high pressure cut-off valve, comprise flap 2, valve rod 3, valve body 1, one end of valve rod 3 is connected with flap 2, flap 2 is arranged in the valve body 1, the other end of valve rod 2 is connected with handwheel 4, and the lumen 11 of valve body 1 is miter angle with the runner hole 12 of valve body 1 and is obliquely installed, and the sealing surface 13 and the runner hole 12 of valve body 1 is the oblique angle sealing.
Claims (2)
1. Y type power station high temperature and high pressure cut-off valve, comprise flap, valve rod, valve body, one end of valve rod is connected with flap, flap is arranged in the valve body, the other end of valve rod is connected with handwheel, it is characterized in that: the runner hole of the lumen of valve body and valve body is the plane of inclination and is provided with, and the sealing surface of valve body and runner hole are the oblique angle sealing.
2. according to claim 1 or 2 described Y type power station high temperature and high pressure cut-off valves, it is characterized in that: the runner hole of lumen and valve body is miter angle and is obliquely installed.
