Abstract
The utility model relates to a hard sealed eccentric semi-spheric face valve, which is an accessory in a fluid transfer pipeline. The utility model is composed of a valve seat, a valve body and a valve clack. The utility model is characterized in that the valve clack is a 'star-shaped turn type structure, the sealing surface of the valve clack is a spheric face, and a two-dimensional eccentricity is arranged on the center of sphere of the spheric face. The eccentricity is also arranged on the center of a shaft and the center of the valve body. A fixed lining is arranged in the valve body, and the valve seat and an adjusting ring are arranged in the fixed lining. The positive effect of the utility model is that the pressure ratio among sealing surfaces can be adjusted. Because the section of the space of the flow channel of the hard sealed eccentric semi-spheric face valve is large, when the valve is fully opened, the axial direction space does not have resistance. The hard sealed eccentric semi-spheric face valve has large flow coefficient and small resistance coefficient. The hard sealed eccentric semi-spheric face valve has the advantages of simple structure and convenient operation.
Description
The utility model relates to the annex in a kind of fluid delivery pipeline, particularly a kind ofly is used to cut off or regulate the hard seal eccentric semi ball face valve that flow is used.
Present applied hard seal butterfly valve, because the defective of its configuration aspects, flap occupies sizable axial space under full-gear, and that gives fluid mobilely causes bigger resistance, and the pressure drop of system is also big, and sealing is also not ideal enough.
The purpose of the utility model is that to disclose a kind of flow area at the deficiency of aforementioned prior art big, and resistance is little, and pressure drop is little, the hard seal eccentric semi ball face valve of good seal performance.
The utility model is achieved in that hard seal eccentric semi ball face valve, and it is by valve seat 3, and valve body 7 and the flap 8 that is contained in the valve body 7 constitute, and wherein: flap 8 is "
" formula that the turns structure of type, the sealing surface of flap 8 is a sphere, the heart has the off-centre of a bidimensional among the centre of sphere of sphere and the axle 9.Among the axle 9 among the heart and the valve body 7 heart one off-centre is arranged.Stationary bushing 5 is contained in the valve body 7, and valve seat 3 and adjustment ring 4 are contained in the stationary bushing 5.Between stationary bushing 5 and valve body 7, sealing gasket 1 is housed, between stationary bushing 5 and valve seat 3, sealing gasket 2 is housed.
Good effect of the present utility model is: 1, the pressure ratio can regulate between the sealing surface.2, big because of the flow channel space cross section of this valve, thus valve when standard-sized sheet, axial space does not have resistance.3, this valve flow coefficient is big, and resistance coefficient is little, and 4, this valve arrangement is simple, easy to operate.
Description of drawings is as follows:
Fig. 1 is a structural drawing of the present utility model.
Wherein:
1, sealing gasket 2, sealing gasket 3, valve seat 4, adjustment ring
5, stationary bushing 6, bolt 7, valve body 8, flap
9, axle
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1: hard seal eccentric semi ball face valve, it is by valve seat 3, and valve body 7 and the flap 8 that is contained in the valve body 7 constitute, wherein: flap 8 is "
" formula that the turns structure of type, the sealing surface of flap 8 is a sphere, the heart has the off-centre of a bidimensional among the centre of sphere of sphere and the axle 9.Among the axle 9 among the heart and the valve body 7 heart one off-centre is arranged.Stationary bushing 5 is contained in the valve body 7, and valve seat 3 and adjustment ring 4 are contained in the stationary bushing 5.Between stationary bushing 5 and valve body 7, sealing gasket 1 is housed, between stationary bushing 5 and valve seat 3, sealing gasket 2 is housed.The sealing surface of valve seat 3 is the annulus sphere.Can select for use manual, electronic, pneumatic and surge according to purposes and this valve drive cassette of needs.When drive cassette drove the rotation of axle 9 clockwise directions, flap 8 can be opened, and when counterclockwise direction was rotated, flap 8 can be closed, and was issued to compressing and sealing of valve seat 3 and flap 8 in the effect of off-centre.
