Wherein, described pivoted pole is plugged in respectively in described each jack, makes the same moving of the hard to bear described pivoted pole of described regulating valve energy and the pivot pendulum.

Wherein, when screwing described bounding means,, described actuating member can't be rotated voluntarily to oppress the limited wall of described actuating member by described bounding means.

Wherein, described valve plates is made by the Furtulon material.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

One, the corrosion of the anti-strong acid of energy, alkali lye body to keep preferable tightness, takes place and keep the normal regulating function and avoid taking place the seepage situation.

Two, its with low cost, simple structure, and processing ease.
