Abstract
The utility model relates to a T-shaped seal hemispheric valve for cutting off or regulating medium flow in a water pipe network. A valve shaft is arranged in the valve body. A transmission device is arranged on the top of the valve body, and is connected with the valve shaft. A sphere seal ring with the T-shaped section is arranged on the hemispheric body through adjusting screws. The central line of the hemispheric body is misaligned with the central line of the valve body; and a seal pair is misaligned with the central line of the valve shaft. The T-shaped seal hemispheric valve adopts the double eccentric hemispheric adjustable T-shaped seal ring structure so that the flow area of the pocket of the valve is maximized and the flow resistance is nearly zero; the mass of the T-shaped seal hemispheric valve is just one-third of the mass of a spheric valve. The T-shaped seal hemispheric valve can seal reliably, and the service life is long.
Description
Technical field
The utility model relates to ball valve, particularly relates to the semispherical valve that water transfer pipe network is done to cut off medium or regulated rate-of flow.
Background technique
Be used for the ball valve that industries such as electric power, metallurgy, oil, chemical industry, city tap-water are done to cut off medium or regulated rate-of flow, its spheroid is whole shape, its valve shaft is in spheroid, and transmission device is connected at the top of valve body and with valve shaft, and sealing pair is in spheroid, the secondary symmetry fully of its valve body and ball seal, in the valve opening and closing process, between valve seat and the ball seal circle friction is arranged all the time, therefore, the ball seal circle very easily weares and teares and has caused the valve leakage, and the valve of leakage need keep in repair or change.The poor sealing performance of its valve, working life is not long.
Summary of the invention
The purpose of this utility model is for the spheroid that overcomes above-mentioned valve is the short shortcoming of whole shape, poor sealing performance, working life, has proposed a kind of T type sealing semispherical valve, and it is that a kind of spheroid is a hemisphere, the valve of good seal performance, long service life.
The technical solution of the utility model is as follows:
The utility model comprises valve body, valve shaft, ball seal circle, valve seat, transmission device, valve shaft is in valve body, transmission device is connected at the top of valve body and with valve shaft, the ball seal circle is in spheroid, it is that ball design is become hemisphere, and ball seal circle and pressing plate are fixed on the spheroid front by adjusting screw, and the ball seal ring cross-section is the T type, sealing pair C and valve shaft center line D skew, ball centre line B and valve body center line A skew.
The beneficial effects of the utility model are:
1, spheroid of the present utility model is a hemisphere, and quality is 1/3 of an existing pipe network ball valve spheroid, and it not only has the characteristic of ball valve, possesses the advantage of gate valve, butterfly valve simultaneously, and flow resistance approaches zero.
2, the utility model adopts T RunddichtringO structure, whole sulfidization molding, can regulate.
3, the utility model adopts two eccentric structures, and during valve opening, ball seal circle and valve seat are thrown off rapidly; When closed, the friction stroke is short, helps protecting seal ring.
4, the utility model circulation area is big, approximate full tunnel, and the pressure loss is very little.
