Save material cost, decrease valve weight simultaneously.The rectangular seal of the left valve seat part of original structure and scraping blade with
Spheroid contacts, and the only one of which plastic seat that after improving, the left valve seat part of structure contacts with spheroid, and rubbing between spheroid
Wipe and reduce, finally make the moment of torsion of valve rod reduce, in order to the on-off action of handle.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: the supporting of the left body of 1-valve body, 2-, 3-spheroid, 4-valve rod, 5-valve seat, 6-valve seat rectangular loop, 7-scraping blade, 8-O shape
Sealing ring, 9-planar spring, 10-handle, 11-hex nut, 12-plastic seat.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this reality
It is further elaborated with novel.
As it is shown in figure 1, a kind of asymmetric valve seat emptying Blowoff ball valve, including valve body 1, left body 2, spheroid 3, valve rod 4, valve seat
Supporting 5 and handle 10, described valve body 1 and the fixing connection of left body 2, the center of described valve body 1 is provided with first passage, in left body 2
The heart is provided with second channel, first passage and second channel and forms axial passage；Spheroid chamber, spheroid 3 it is provided with in described axial passage
It is arranged on spheroid intracavity；Described spheroid 3 top is fixing with valve rod 4 bottom to be connected, and described handle 10 is fixed on valve rod 4 top；Institute
State and have on valve body 1 and the hole of valve rod 4 adaptation；Be provided with on the right side of described spheroid 3 valve seat supporting 5, valve seat support 5 left end inner surfacies with
Spheroid 3 surface contacts；It is additionally provided with valve seat rectangular loop 6 and scraping blade 7, described valve seat rectangular loop 6 and scraping blade 7 in described valve seat supporting 5
Interlocking supports 5 left end inner surfacies at valve seat；It is step-like that described valve seat supports 5 cylindricals, described left body 2 left end inner surface and valve seat
Support 5 cylindrical laminatings；Plastic seat 12, described plastic seat 12 right part inner surface and spheroid 3 surface it is provided with on the left of described spheroid 3
Contact；Being provided with and the groove of plastic seat 12 adaptation in described valve body 1, described plastic seat 12 is inlaid in valve body 1.
