High-water-head valve top water stop fixing method
A high-water-head valve top water stop fixing method is characterized in that two rows of fixing bolts are added on the basis of existing top water stop single-row fixing bolts, are parallel to original single-row fixing bolts and are symmetrically arranged on the left side and the right side of the original single-row fixing bolts to form three rows of transverse fixing bolts, and the newly addedfixing bolts are transversely located on the symmetry axis of every two adjacent original fixing bolts; the fixing bolts are staggered with original fixing bolts, and original single-row one-line arrangement is changed into three-row quincunx arrangement, so that the top water stop is fixed and restrained more tightly in a larger area, the problem of uneven compression of the single-row fixing bolts to the water stop is solved, and meanwhile uneven tensile deformation of the water stop under the condition of high water head pressure is reduced. The service life of a top water stop is effectively prolonged.
一种高水头阀门顶止水固定方法，在目前顶止水单排固定螺栓的基础上，增加两排固定螺栓，与原有的单排固定螺栓平行，对称布置于其左右两侧，形成横向三排固定螺栓，新增的固定螺栓沿横向位于相邻的两个原有固定螺栓的对称轴线上，与原有固定螺栓错位布置，从原有的单排一线布置变为三排梅花形布置，从而使顶止水受到更大面积、更加紧密的固定约束，解决了单排固定螺栓对止水压缩不均匀问题，同时减小了止水在高水头压力条件下的不均匀拉伸变形，有效延长顶止水的使用寿命。
