Deflector 6, pad 8 is respectively provided between deflector 6 and valve body 1 and side valve body 7, and pad 7 is flexible graphite material, strengthens valve
The sealing property of door；Deflector 6 forms sealing surface, ball built with sphere cylinder valve element 2, sphere cylinder valve element 2 with the middle part of valve body 1
Guide rod 13 is provided with face cylinder valve element 2, and guide rod 13 is stepped into three-level, sphere cylinder valve element step 11 and ball
Face cylinder valve element three-level ladder 12 contacts guiding with deflector 6 simultaneously, ensures that sealing does not misplace；Sphere cylinder valve element 2 with
Compression spring 3 is housed between deflector 6, sphere cylinder valve element 2 is suppressed using spring 3, strengthens the sealing property of valve；Valve body 1
Pressure release passage 14 is inside provided with, pressure release passage 14 is shoulder hole 17, and being matched in shoulder hole 17 has taper valve core 16, and taper valve core 16 is right
End is pressed with pressure release spring 15 in advance, and when Opening pressure is excessive, taper valve core 16 moves right, and plays a part of protecting valve.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model is extended out and still fall within this practicality
New protection domain.
