Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of novel hard seal ball valve includes mainly valve rod 1, valve body, and the valve body includes connector 2, valve block 8, and connector 2 is inserted
Enter in valve block 8,2 inside setting sphere hole of connector and runner 3, the installation sphere 4 for being used for being adapted in sphere hole, is set on sphere 4
Jack 5 is set, the jack 5 is connected to runner 3, and the diameter in sphere hole is more than the area in 3 section of runner, and runner 3 is used with jack 5
In the flowing of water body；Connecting hole is respectively set in valve block 8 and sphere 4, one end of the valve rod 1 is inserted in sphere across connecting hole
In 4, valve rod 1 can drive sphere 4 to rotate, the registration of adjusting jack 5 and runner 3, and the registration of jack 5 and runner 3 can
The size for adjusting flow, in the utility model, the sphere 4 is used for blocking runner, and only jack 5 has the portion overlapped with runner 3
Timesharing could pass through flow in jack 5.
The structure and preferred embodiment of following detailed description the utility model：
In the utility model, the sphere 4 and the combination of valve rod 1 are equivalent to an open-close on-off, when sphere 4 rotates to one
When determining angle, the sphere 4 can block runner 3, and when runner 3 and jack 5, which have, to be overlapped, flow can flow out, therefore be
Facilitate rotation valve rod 1, one handle 6 is installed on valve rod 1, valve rod 1 can be made easily to rotate by handle 6.Due to sphere 4
It is rotated in connector 2, therefore a valve seat 7 is installed in connector 2, what the sphere 4 was adapted to is contained in valve seat 7, uses
The purpose of valve seat 7 is so that valve seat 7 and 4 contact position of sphere is had one section of circular arc, and manufacture circular arc one is that technique is multiple in connector 2
It is miscellaneous, second is that when there is abrasion in contact position, integral replacing connector 2 is needed, wastes material and funds, and valve seat 7 is used to be used as part,
Valve seat 7 can be directly replaced, it is easy to maintenance.Wherein, sphere 4 is with valve seat 7 using the cambered surface of round and smooth contact, and cambered surface is compared to plane
Sealing effect it is more preferable.
The valve rod 1 is in staircase structural model, and there are multiple step surfaces, the lower end of valve rod 1 to be connected with sphere 4 by slot or key
It is connected together, groove is respectively set in the upper and lower ends of the connector 2, and a part of valve block of valve body is contained in groove, to two
Person is combined together, and valve rod 1 links together with sphere 4 again after passing through valve block 8, and the valve rod 1 is connected by valve block 8 and sphere 4
It connects, sphere 4 is in close contact with valve seat 7.Valve rod 1 seals pressure up for safekeeping with valve block 8, and valve rod 1 is realized by 6 transfer motion power of handle and adjusted
Pressure of the valve rod 1 to sphere 4 is saved, sealing ring 11 is set on valve rod 1, the setting of sealing ring 11 can seal pressure, regulating valve stem up for safekeeping
Pressure between 4 surface of step surface and sphere, when valve rod 1 is pressed downward, valve rod step surface is tightly contacted with spherome surface, simultaneously
The pressure of pushing also adjusts the pressing force between sphere 4, valve seat 7, so that sphere 4 and the arc surface of 7 contact position of valve seat is formed good
Good sealing, water will not flow out between sphere 4 and valve seat 7.The upper and lower surface contact of sphere 4 is in valve block 8, connector 2 and valve
Gasket or spring can also be arranged in 8 junction of block, automatic to compensate valve seat 7 and 4 contact gap of sphere.
Banking stop 9 is set on connector 2 or valve rod 1, pin 10, limit are set between valve block 8 and the end cap for compressing valve rod
Piece 9 limits the angle and direction that valve rod 1 rotates, such as banking stop 9 can limit the rotational angle in one direction of valve rod 1, and one
Valve rod 1 on a direction may only rotate 45 degree to 90 degree, and specific rotation angle can be controlled according to actual needs.With
On the basis of the rotation in one direction, such as when rotating in the forward direction 1/4 circle (90 °), do not overlapped between valve breakdown, i.e. runner and jack
Part, flow block；When reversely rotating 1/4 circle (90 °), valve is opened, i.e., has intersection, flow between runner and jack
Flowing.
During flow flows, sphere 4 is under the action of pretightning force and Fluid pressure, at sphere and valve seat arc contact
It compresses, sealing surface of seat is deformed and reaches sealing.In the utility model, work of the valve seat in Fluid pressure and pretightning force
It can compensate for sphere out-of-roundness and the defect of nao-and micro relief under, reach best sealing effect.
In order to realize that better seal effect, the valve seat 7 make using with hardenable alloys steel, not easy to wear, sphere 4
Using ceramic making, valve seat 7 and the surface of sphere 4 are ground, make sphere it is smooth during rotation, reduce mill
Damage, and the use of above-mentioned material make this product have the characteristics that high temperature resistant, anti abrasive.
When use, the both ends of connector 2 are connected on pipeline, adjust the compression journey between valve rod step surface and sphere
Degree drives any angle that sphere rotates together 0 ° to 90 ° by handle, and realization between jack and runner is made arbitrarily to overlap,
To realize the control of flow, the break-make and flow control function of spherical ball valve.Standard-sized sheet or it is fully closed when, the sealing of sphere and valve seat
Face is isolated with medium, medium by when will not cause the erosion of valve sealing face.
The present invention is realizes that the on and off function of high pressure gas or liquid provides a kind of install convenient, safe, low
The utility of cost.
The preferred embodiment that these are only the utility model embodiment is not intended to limit the utility model implementation
Example, all within the spirit and principle of the utility model embodiment, any modification, equivalent replacement, improvement and so on should all wrap
It is contained in the protection domain of the utility model embodiment.
