Using the larger problem that rubs, the use for further increasing ball valve can the service life.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of novel PPR ball valve, including valve body, valve
The both ends of body are respectively arranged with water supply connector, water outlet connector by attaching nut, and opening and closing element is equipped in valve body, is provided on valve body
Positioning convex column, positioning convex column are provided with perforation to the intracorporal mesoporous of valve, and opening and closing element is connected with valve rod, and valve rod is used in combination through mesoporous is gone out
Fixture nut is connected with the one end corresponding with opening and closing element of mesoporous described in handle and is provided with installing locating slot, is provided with and pacifies on valve rod
The matched positioning convex platform of locating slot is filled, is provided in the positioning convex column using the central axis of mesoporous as center even circumferential several
Cushion hole, cushion hole one end penetrate through to positioning convex column upper surface, the other end and penetrate through to installing locating slot, setting in the cushion hole
There is buffer spring, the both ends of buffer spring are respectively arranged with locating piece, between the locating piece and positioning convex platform, handle, at its lower end face
It is respectively arranged with roller ball, setting and the matched rotational positioning slot of roller ball radian on locating piece；Be arranged on the valve rod with
The matched lower positioning plate of installing locating slot, lower positioning plate are between positioning convex platform and roller ball, are arranged on the lower positioning plate
Have and the matched lower annular positioning groove of roller ball radian.
Positioning plate is provided on the valve rod and between positioning convex column upper surface and handle, be provided on upper positioning plate with
The matched upper annular positioning groove of roller ball radian.
The diameter of the roller ball is less than the diameter of cushion hole.
Installation gap is respectively provided between the upper positioning plate, lower positioning plate and valve rod.
The locating piece, upper positioning plate and lower positioning plate are all made of polytetrafluoroethylene material.
The beneficial effects of the utility model are:
Compared with conventional art, for the utility model when installing valve rod, rolling can be passed through by twisting the excessive power of fixture nut
Ball, locating piece act on buffer spring, thus fallen pressure buffer of twisting excessive in fixture nut by buffer spring,
Therefore it can effectively avoid the power for twisting nut during installation excessive and cause between positioning convex platform and locating slot, handle and fixed
Adhesive force tension causes there is a problem of larger using rubbing between the pillar upper surface of position；Rotational handle band ovable valve stem rotates simultaneously
When, positioning convex platform is relatively rotated by being formed between lower positioning plate and roller ball, and handle passes through between upper positioning plate and roller ball
It is formed and is relatively rotated, to further effectively avoid twisting excessive power in fixture nut during ball valve opens and closes use
Caused by rub；Effectively further increase the service life of ball valve.
