Sealing;Meanwhile, during sealing surface wear between valve seat and valve element, flexible member can timely promote valve seat to make compensation, from
And it is not susceptible to the leakage leading to because of the abrasion of sealing surface.
(2) setting of positioning sleeve, not only can realize centering and guiding to valve element in the motion of valve cavity, can be effective
Guarantee top end of the valve body valve opening not easy to wear, meanwhile, also increased a cushion chamber newly in original valve body epicoele, along with fixed
Position set and in sealing contact, such valve body epicoele entering under water environment even at higher pressure of valve element, are not easy to occur from valve opening
The situation of place's leakage.
(3) it is additionally provided with the water-level instrumentation connecting alarm unit in cushion chamber, seal bad between positioning sleeve and valve element
When there is leakage, water-level instrumentation in time detection can send alarm to relevant information and by alarm unit.
