Abstract
The utility model relates to a compensating hemisphere valve for cutting off or regulating the medium flow in a water pipe network. A valve shaft is arranged in the valve body and a sphere. A transmission device is arranged on the top of the valve body, and is connected with the valve shaft. A sphere seal ring is arranged on the sphere. The sphere is designed to be in a hemispheric shape. The sphere seal ring is connected in front of the sphere through allen type socket screws; set screws are arranged behind the sphere; the central line of the sphere is misaligned with the central line of the valve body; a seal pair is misaligned with the central line of the valve shaft. The compensating hemisphere valve adopts the double eccentric hemispheric structure compensating the seal pair by regulating the set screws so that the flow area of the pocket of the valve is maximized and the flow resistance is nearly zero; the mass of the compensating hemispheric valve is just one-third of the mass of a spheric valve. The compensating 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
The ball valve that is used for electric power, metallurgy, oil, chemical industry, city tap-water industry work partition or adjusting rate-of flow, its spheroid is whole shape, its valve shaft is in spheroid, transmission device is connected at the top of valve body and with valve shaft, and the ball seal circle is generally rubber or rubber-coated or metal hard-sealing structure.Valve has friction between valve seat and the ball seal circle all the time in opening-closing process.Therefore, the ball seal circle weares and teares easily and causes valve to reveal, and sealing is poor.The valve of revealing need keep in repair or change, and working life is short.
Summary of the invention
The purpose of this utility model is for the spheroid that overcomes above-mentioned valve is whole shape, valve seal poor performance, the shortcoming that working life is short, proposed a kind of compensation semispherical valve, it is that a kind of spheroid is a hemisphere, good seal performance, can compensate the valve of long service life behind the ring wear.
The technical solution of the utility model is as follows:
The utility model comprises valve shaft, valve body, ball seal circle, transmission device, valve shaft is in valve body, transmission device is at the valve body top, and the ball seal circle is on spheroid, and it is that ball design is become hemisphere, the ball seal circle is connected in the front of spheroid by screw, Cock screw after the wearing and tearing of ball seal circle, is regulated additional sealing with Cock screw in the back of spheroid, and sealing pair valve shaft disalignment, ball centre line and valve body disalignment.
The utility model beneficial effect is as follows:
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 two eccentric structures, and during valve opening, ball seal circle and valve seat are thrown off rapidly, and the friction stroke is short, helps protecting seal ring.
3, the utility model can compensate ball seal circle concentrated wear amount by regulating Cock screw, effectively guarantees sealing effect, prolongs seal ring and valve working life.
4, the utility model circulation area is big, approximate full tunnel, and the pressure loss is very little.

Fig. 2 is the utility model plan view.
Embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing:
1, valve shaft 2, valve gap 3, valve body 4, ball seal circle 5, socket head screw 6, spheroid 7, Cock screw 8, lower valve shaft 9, valve seat 10, transmission device A, valve body center line B, ball centre line C, sealing pair D, valve shaft center line
In Fig. 1~2: valve shaft (1) is in valve body (3), the valve gap (2) that transmission device (10) is contained in valve body (3) top upward and with valve shaft (1) is connected, spheroid (6) is a hemisphere, be connected with lower valve shaft (8) with valve shaft (1) respectively, ball seal circle (4) is connected the front of spheroid (6) by socket head screw (5), Cock screw (7) is contained in spheroid (6) back, sealing pair (C) and valve shaft (1) center line (D) skew, ball centre line (B) and valve body center line (A) skew.
