On at least two rings wherein circular hole have diameter be greater than circular hole other positions circular hole export, i.e., circular hole outlet bore most
Greatly, realize to outflow when,.
The present embodiment 1 illustrates using the valve seat 4 with two circle circle distribution circular holes 5, but in use may be used
According to different actual conditions, the valve seat 4 of the quantity of different circular holes 5, size and shape is replaced by disassembly valve body to expire
The specific duty requirements of foot can choose the valve seat 4 of only one circle circle distribution circular hole 5, also can choose and be made of completely circular hole 5
Valve seat 4.It can be optionally combined according to the difference of 4 use environment of ball valve, can achieve flow-adjustable in a certain range,
Guarantee that adjusting essence is greatly improved according to set objective progress assignment of traffic in each lateral under " one-to-many " arrangement form
Degree.
The present embodiment 1 is equipped with locking spring gasket 11 for the reliability and sealing performance of scheme on the bolt 10,
Prevent airtight and watertight padding 14 because cause when valve rod 3 rotates abrasion loosen and valve seat 4 on open there are two inner groovy, upper cover 7 and/or
Also it is provided with groove on valve body 1, O-ring seals 8 are equipped in groove, so that the sealing performance of product further increases, it is described O-shaped
Sealing ring 8 movable can be replaced, and replacement can be carried out to remain good by reaching under different medium after centainly using the time
Good sealing performance.
The present invention improves sphere and valve seat matrix hardness using special heat treatment process and process of surface treatment, specifically
Refer to: the sphere 2 and valve seat 4 uses the two phase stainless steel of 17-4PH precipitation hardenable, and passes through at solid solution and Vacuum Heat
Reason, matrix hardness is up to 40HRC, while in 1 inner cavity of valve body, sphere 2 and 4 surface of valve seat all above thickness of surfacing 0.3mm
68HRC or more can be improved in WC cemented carbide layer, surface hardness, greatly improve valve body 1, sphere 2, valve seat 4 it is resistance to
The performance of mill and antiscour.
It should be understood that realizing the regulatory function of valve using the valve seat of novel porous current limliting.Medium passes through valve seat
Aperture outflow flow direction become parallel with pipeline, only valve body generation will not be washed away strongly, while valve seat is replaceable structure, it is square
Just later maintenance, to protect valve body.Valve base surface entirety surfacing chromium carbide, improves its surface hardness, more resistant to washing away, improves
The service life of valve.Viscous medium or particle block adjustment hole, the tapered hole that there is circular hole mouth to go out in order to prevent.
Embodiment 2
A specific embodiment of the invention as shown in Figure 4, the present embodiment 2 is substantially the same manner as Example 1, the difference is that being additionally arranged
Circular hole constriction 17, and the structure of script valve seat 4 Yu circular hole 5 is changed, it is specific as follows: in the through-hole two of the sphere 2
Circular hole constriction 17 is additionally arranged on side, circle distribution has circular hole 5, the circular hole 5 and embodiment 1 on the circular hole constriction 17
The difference is that the structure of the circular hole 5 is to be connected to constitute by one large one small cylindrical hole, the present embodiment is eliminated
Circular hole 5 is dispensed directly onto the structure on valve seat 4, becomes and adds circular hole constriction 17 on valve seat 4, and circular hole 5 is allowed to be distributed in circle
On hole constriction 17, when medium passes through the shape circular hole 5, flow velocity can significantly be weakened, and reduce medium to valve body 1, valve seat 4
And the scouring force of sphere 2, while the circular hole constriction 17 added significantly improves regulating power.
Embodiment 3
A specific embodiment of the invention as shown in Figure 5, the present embodiment 3 is substantially the same manner as Example 1, the difference is that being additionally arranged
The circular hole constriction 17 of helicoidal structure, it is specific as follows: on 2 through-hole of sphere and to be additionally arranged circular hole on 4 two sides of valve seat
Constriction 17,5 structure of circular hole of circular hole constriction 17 are divided into clockwise spiral and counter-clockwise helical shape, and medium is logical by fluid
It will become and rotate clockwise when being come out again when road enters the circular hole 5 of first circular hole constriction 17, then from second circular hole current limliting
The circular hole 5 of part 17 will become rotation counterclockwise when coming out again, so pass through other two circular hole constriction 17 again.In the present embodiment
The flow velocity of medium in 3 will be slowed to utmostly, be suitble to use in requiring the conciliation higher operating condition of precision.
Simultaneously it may be noted that the term pointed out of the present invention, such as: "front", "rear", "vertical", "horizontal", instruction side
Position or positional relationship are to be based on the orientation or positional relationship shown in the drawings, and are merely for convenience of description of the present invention and simplification of the description,
Rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, because
This should not be understood as limiting the scope of the invention.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
