Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 2, in this specific embodiment, a kind of fast opening and closing semisphere valve of the utility model, including valve
Body 1, spool 3 and valve seat 4, which is characterized in that 1 inner cavity of valve body is equipped with flow channel and flow pass, and the spool 3 is installed
Between the flow channel and the flow pass, 3 upper and lower end of spool is connected separately with fixed device and lower fixation
Device, fixed device, the spool 3 and the lower fixed device form movable stationary structure, and the valve seat 4 is arranged
In forming surface seal structure close to flow channel end, 4 one transverse plane of valve seat and 3 spherical surface of spool, the valve seat 4 is another
Transverse plane connect to form floating sealing structure with floating ring 2.
With the above arrangement, the installation positioning of spool 3 realizes Fast Installation positioning using movable stationary structure design,
Promote installation effectiveness；The connection of valve seat 4 and floating ring 2 uses floating sealing structure, and when valve seat 4 is worn, floating ring 2 is certainly
Dynamic compensation squeezes valve seat 4, and then guarantees that the surface seal structure of sealing, the structure and valve seat 4 and spool 3 forms dual-seal.
Upper fixed device includes upper valve rod 6 and Self-lubricating Stuffing 7, and the upper valve rod 6 is filled through the valve body 1 with driving
Connection is set, the Self-lubricating Stuffing 7 is set between the valve rod 6 and the valve body 1, and forms upper valve rod by the compression of gland 5
Self-lubricating seal structure, upper valve rod 6 are that spline is connect with the connection of the spool 3, and the bond number of the spline connection is at least 2
It is a；Lower fixed device includes lower valve rod 8, axle sleeve 9 and end cap 10, and the lower valve rod 8 is set to the mounting hole of 1 bottom of valve body
