Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a regulation formula V type ball valve.

In the embodiment, referring to fig. 1 to 3, the adjustable V-shaped ball valve includes a valve body 1, a valve core 2 and a valve rod 3, a medium inlet and a medium outlet communicated with each other are disposed on two sides of a valve cavity of the valve body 1, a valve seat 4 sealingly engaged with the valve core is disposed on the valve body on one side of the medium inlet, the valve seat 4 includes an annular base 5, an annular sealing ring 6, a sealing ring 7 and a spring 8, the annular base is provided with a "T" -shaped annular groove 9, the annular sealing ring is provided with a "T" -shaped connection ring 10 engaged with the "T" -shaped annular groove 9, the "T" -shaped connection ring 10 is embedded into the "T" -shaped annular groove 9, one end of the spring is fixed on a bottom wall of the "T" -shaped annular groove, the other end of the spring abuts against the "T" -shaped connection ring, an arc-shaped surface 11 engaged with, the sealing ring 7 is embedded in the embedding groove of the arc-shaped surface 11.

Among the above-mentioned technical scheme, set up the disk seat into annular base and annular sealing ring two parts to bury the spring in the "T" type annular groove of annular base, thereby avoid the spring directly to be washed away by the medium, also isolated the contact of medium with the spring, avoid the spring to receive the medium influence and corrode, improved the deadline of spring greatly, also improved the whole life-span of valve.
