Recessed molding is equipped with the first gap floated for elastomeric element between the spherical crown and First terrace.
Further, the spool is equipped with the second step face of fixed spherical crown, and the spherical crown is lived by several connectors
Dynamic to be mounted on spool, the connector is inserted on second step face.
Further, the spherical crown is equipped with for sealing
Further, the sealing ring includes sealing and several fixed parts that self sealss portion both sides are symmetrically formed, institute
The fixed part of sealing unilateral side is stated into zigzag.
Compared with prior art, the utility model has at least the following advantages：
1. the utility model valve is closed, spherical crown can be close to valve under the action of the sealing ring with self sealss performance
Seat, and can automatic capturing optimal seal position.
2. the utility model, under high pressure operating mode, flexible deformation occurs for spool, elastomeric element is stretched as spool deforms
Truncate repays deflection, to protect the relative position of sealing pair not change.
3. abrasion and compensation that the elastomeric element of the utility model can be generated with secondary long-term mutually move of compensation sealing
Mismachining tolerance.
4. the utility model safeguards that simply spherical crown is when something goes wrong, it is only necessary to back out connector and more renew spherical crown.
Description of the drawings

Fig. 2 is the partial enlarged view of part A in eccentric half-ball valve shown in FIG. 1.
Fig. 3 is the partial enlarged view of the eccentric half-ball valve of the utility model embodiment two.
Fig. 4 is the partial enlarged view of the eccentric half-ball valve of the utility model embodiment three.
Specific implementation mode
The structure and utility model content of the eccentric half-ball valve of the utility model are described with reference to Fig. 1 to 4.
Embodiment one：
As illustrated in fig. 1 and 2, a kind of eccentric half-ball valve of the utility model, including valve body（It is not shown）, be arranged in valve inner
Valve seat 1, with valve seat 1 sealing cooperation spool 2, mounted on spool 2 elastomeric element 3 and secure resilient member 3 spherical crown 4 with
And the sealing ring 5 on spherical crown 4.The spherical crown 4 and sealing ring 5 are respectively formed sealing pair with valve seat 1.
The valve seat 1 is mounted on the medium runner of valve body, and is sealed and coordinated with the spool 2, realizes the medium of valve body
The break-make of runner.
The spool 2 is equipped with First terrace 6 and second step face 7 at hemispherical successively on spherical surface.The First
Terrace 6 is concavely provided with the mounting groove 8 of installation elastomeric element 3.The mounting groove 8 is towards valve seat 1.
The elastomeric element 3 can be with elastomers such as spring, rubber.
The spherical crown 4 is set on spool 2 and is pressed on elastomeric element 3.The spherical crown 3 coordinates with First terrace 6
And it is equipped with the first gap floated for elastomeric element 3 between the two.First gap can be used for compensating spherical crown 4 and valve seat 1
Between sealing loss.
The spherical crown 4 is movably arranged on by several connectors 9 on the second step face 7 of spool 2.The connector 8 is inserted
Enter on second step face 7.The connector 9 uses screw.The connector 9 can be used for adjusting between spherical crown 3 and spool 2
First gap ensures the space of spherical crown 4.
The spherical crown 4 is equipped with the seal groove 10 installed for sealing ring 5.Between the sealing ring 5 and seal groove 10 there are
Second gap, such medium enters behind the second gap provides self sealss power to sealing ring 5.
The sealing ring 5 includes sealing 11 and several fixed parts 12 that 11 both sides of self sealss portion are symmetrically formed.It is described
The unilateral fixed part 12 of sealing 11 is at zigzag.
The utility model is since sealing ring 5 has self sealss performance, when spherical crown 4 contacts with each other with valve seat 1,4 energy of spherical crown
It is close to 1 surface of valve seat and automatic capturing optimal seal position；Spherical crown 4 reaches under the action of elastomeric element 3 after valve is thoroughly closed
To initially than swaging at sealing；Under high pressure operating mode, flexible deformation occurs for spool 2, and elastomeric element 3 is deformed with spool 2 and stretched
Truncate repays deflection, to protect sealing pair relative position not change；The eccentric half-ball valve maintenance of the utility model is simple,
Spherical crown 4 is when something goes wrong, it is only necessary to back out connector 9 and more renew spherical crown；And the eccentric half-ball valve of the utility model by
Certain sealing force is provided in elastomeric element, so the torque of valve opening is slim and graceful.
Embodiment two：
The present embodiment and the structure of embodiment one are essentially identical, the difference is that only：The spherical crown 4 ' and valve seat 1 ' are not
Contact, does not form sealing pair.Only sealing ring 5 ' forms soft seal pair with valve seat 1 '.The elastomeric element 3 ' is also to sealing ring 5 '
The soft seal pair formed with valve seat 1 ' plays compensating action.
Embodiment three：
The present embodiment and the structure of embodiment one, two are essentially identical, the difference is that only：It is not equipped on the spherical crown 4 "
Sealing ring.The spherical crown 4 " is in direct contact to form hard sealing pair with valve seat 1 ".The elastomeric element 3 " is also to spherical crown 4 " and valve seat
1 " the hard sealing pair formed plays compensating action.
In conclusion the above is only the preferred embodiments of the present utility model only, the utility model should not be limited with this
Range.It is i.e. every according to simple equivalent changes and modifications made by the utility model claims book and description, all answer
Still belong in the range of the utility model patent covers.
