Abstract
The utility model is related to a kind of eccentric ball valve, more particularly to a kind of eccentric three-way ball valve with L-type passage.So far, the valve mechanism of eccentric ball valve is also limited to straight-through one-way flow two, sealing structure, directly influences the expansion of its application field.Eccentric three-way ball valve of the present utility model, is mounted on supporting valve seat in the porch of passage one and passage two, and it has sealing ring and the installation step of housing between；Billiard table valve element a and billiard table valve element b are separated by 90 °, and with circumferential breach, the sealing pair of annular are provided with the breach, can respectively with passage one and passage two on sealing ring gluing, sealing；Axle sleeve is socketed with valve shaft, and the rotation axis of the valve shaft is with the axis runout of passage one and passage two apart from e.Solve that common tee ball valve Opening pressure is bigger than normal, sealing structure frictional force big, the short defect of service life.
Description
Technical field
The utility model is related to a kind of eccentric ball valve, more particularly to a kind of eccentric three-way ball valve with L-type passage.
Background technology
Eccentric ball valve is a kind of novel valve emerging in recent years, because its stream is simple, self-cleaning property is good, volume
It is small, open it is light the advantages of, quickly grown in application fields such as stream-fixed double phase flow, gas-solid phases.But so far, should
Valve mechanism is also limited to straight-through one-way flow two, sealing structure, directly influences the expansion of its application field.
Utility model content
Technical problem to be solved in the utility model is：Solve that common tee ball valve Opening pressure is bigger than normal, sealing structure
Frictional force is big, the short defect of service life.
A kind of eccentric three-way ball valve with L-type passage, including housing, include thering is the logical of same axis in the housing
Road one and passage two, and the passage three orthogonal with above-mentioned passage, are mounted in the porch of the passage one and passage two
Support valve seat, it has sealing ring and the installation step of housing between；Valve element includes billiard table valve element a, billiard table valve element b and axle sleeve,
The billiard table valve element a and billiard table valve element b are separated by 90 °, and are integrally formed with the axle sleeve, and with circumferential breach, in the breach
In be provided with annular sealing pair, can respectively with the passage one and passage two on sealing ring gluing, sealing；The axle sleeve with
Valve shaft is socketed, and the axis runout of the rotation axis of the valve shaft and the passage one and passage two is apart from e.
Further, the sealing pair is fixed on the billiard table valve element a and billiard table valve element b by pressing plate and dormant bolt
On.
Further, the support valve seat has circumferential inside groove, and adjusting gasket and waveform are provided with from inside to outside
Spring, the wavy spring is abutted with the sealing ring.
Further, the housing is connected by screw with support valve seat.
Further, the valve shaft is used to be bonded and connect with axle sleeve.
Further, the billiard table valve element a and billiard table valve element b are integrally formed by connecting rod with the axle sleeve respectively.
Beneficial effect：There is provided a kind of new L-type double eccentric three-way ball-valve structures, can be applied to multichannel flow regulation,
The structure stream is simple, self-cleaning property is good, and small volume, unlatching are light, itself have sealing compensation structure, in fluid applications especially
It is that the application fields such as stream-fixed double phase flow, gas-solid phase have a good application prospect and economic benefit.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model eccentric three-way ball valve.
Wherein, valve seat is 1. supported, 2. housing, 3. sealing pair, 4. pressing plate, 5. dormant bolt, 6. valve element, 7. valve shaft, 8. close
