Abstract
A kind of valve component structure of control ball valve, belongs to control ball valve fitment.Including valve seat body, it is characterized in that the excircle of valve seat body is equipped with the first seal groove, the inner periphery of valve seat body is equipped with the second seal groove, first seal groove embeds the first sealing ring, second seal groove embeds the second sealing ring, and the valve seat body is closed or opened and closed connection cooperation by the second sealing ring and spool.Valve seat construction described in above-mentioned utility model is simply ingenious, and solid and reliable in the seal groove of the second sealing ring inserted valve seat, which has certain line footpath not easy to wear, and the width bigger of the line diameter ratio valve base sealing slot, and clamping is tighter, not easily to fall off.
Description
Technical field
The utility model belongs to the technical field of control ball valve fitment, and in particular to a kind of valve component knot of control ball valve
Structure.
Background technology
It is one group of mutually matched component to control the valve seat of ball valve and spool, its leakproofness is to examine its valve after the two contact
One major criterion of weight.The use of control valve will cause the opening and closing sum of fundamental frequencies of spool numerous, and the abrasion of washer will can not
It avoids, the simple washer of existing basic use is attached on valve seat, and how long have more than is needed must replace, very troublesome.
Utility model content
For the above-mentioned problems in the prior art, the utility model aim is to provide a kind of valve seat of control ball valve
The technical solution of modular construction.
A kind of valve component structure of control ball valve, including valve seat body, it is characterised in that outside valve seat body
Circumference is equipped with the first seal groove, and the inner periphery of valve seat body is equipped with the second seal groove, and first seal groove embedded first is close
Seal, second seal groove embed the second sealing ring, the valve seat body closed by the second sealing ring and spool or
Person opens and closes connection cooperation.
The valve component structure of a kind of control ball valve, it is characterised in that second seal groove is several planes
Hooked structure made of enclosing, the opening width of second seal groove are less than the line footpath of the second sealing ring.
The valve component structure of a kind of control ball valve, it is characterised in that second seal groove is five planes
Enclose, the second sealing ring with five planes are tangent touches.
The valve component structure of a kind of control ball valve, it is characterised in that first sealing ring and the second sealing
Circle is all made of " O " type rubber material.
The valve component structure of a kind of control ball valve, it is characterised in that the spool vertical direction is provided with logical
Hole, on the right side of through-hole, i.e. spool right side is provided with the circular arc segment spherical surface body for seal spool；In the left side of through-hole,
That is the left side of spool is provided with the cylinder processed for auxiliary circular arc segment spherical surface body.
The valve core structure of a kind of flow control valve, it is characterised in that spool, circular arc segment spherical surface body and cylinder
Integrally casting shaping.
Valve seat construction described in above-mentioned utility model is simply ingenious, securely may be used in the seal groove of the second sealing ring inserted valve seat
It leans on, which has certain line footpath not easy to wear, and the width bigger of the line diameter ratio valve base sealing slot, and clamping is tighter, is not easy
It falls off.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that valve seat is connected with spool；
Fig. 3 is the partial enlarged view of Fig. 1；
Wherein：1- spools, 2- valve seats main part, the second sealing rings of 3-, the first sealing rings of 4-, the first seal grooves of 5-, 6- second
Seal groove.
Specific implementation mode
Below in conjunction with attached drawing the utility model is described in further detail explain.
As shown in Figs. 1-3, a kind of valve component structure of control ball valve, including valve seat body 2, the outer circle of valve seat body 2
It is equipped with the first seal groove 5 week, the inner periphery of valve seat body 2 is equipped with the second seal groove 6, first seal groove embedded first
Sealing ring 4, second seal groove embed the second sealing ring 3, and the valve seat body 2 passes through the second sealing ring and spool 1
Closing or folding connection cooperation.Second seal groove 6 is hooked structure made of several planes enclose, this is second close
The opening width of sealing groove 6 is less than the line footpath of the second sealing ring 3.
Second seal groove 6 is that five planes enclose, the second sealing ring 3 with five planes are tangent touches.Institute
The first sealing ring and the second sealing ring stated are all made of " O " type rubber material.
1 vertical direction of spool is provided with through-hole 7, and on the right side of through-hole, i.e. spool right side is provided with for valve
The circular arc segment spherical surface body 8 of core sealing；In the left side of through-hole, i.e. the left side of spool is provided with for auxiliary circular arc segment spherical surface
The cylinder 9 that body 8 is processed.Spool 1, circular arc segment spherical surface body 8 and 9 integrally casting shaping of cylinder.
When assembly, the second sealing ring 3 is packed into the second seal groove 6, the second sealing ring is made of special rubber material
（Supplement specific material）, more much higher than general rubber material times of abrasion resistance.It is close it to be packed into first in the first seal groove 5
Seal 4, valve seat is fixed in external support members, is sealed by the first sealing ring.Spool and valve seat main part coordinate, when needing to close
When valve closing door, spool is rotated by outer force effect, and wherein one side will be touched with valve seat main part, that is, the side circle
8 structure of arc segment spherical surface body is touched with the second sealing ring 3, prevents substance circulating.When needing to open, backwards rotation valve
Core makes circular arc segment spherical surface body structure be detached from the second sealing ring 3 and is reached at this point, valve core through hole will be connected with the through-hole of valve seat
It is simple and convenient to unlatching circulation effect.Spool is set constantly to open since 6 multi-panel of the second seal groove encloses hooked structure
In closing course, it is always ensured that the work of the normal firm stable of the second sealing ring.
It should be appreciated that the specific embodiments described herein are only used to explain the utility model, it is not used to limit
The utility model.
