This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.

本项目是一种新型结构的直动式溢流阀，采用动压反馈原理，在普通直动式溢流阀阀芯上增加一反馈腔，当阀口溢流时，阀口的液压力与反馈腔液压力和弹簧力相平衡，从而可以减小弹簧的刚度，等于增设了一根液压弹簧，使其和机械弹簧一起工作，以达到减小阀口压力变化范围的目的。

Sub-volcanic rocks include andesitic porphyrite, rhylitic porphyry, cryptoexplosive breccia as well as autobreccia etc.(2) Volcanic lithofacies——through the observation of cores, identification of thin sections and interpretation of well logs and seismic data, there are 8 kinds of lithofacies for the volcanic rocks of Yingcheng Formation are identified: fallout facies, effusion facies, pyroclastic flow facies, base surges facies, lahar facies, eruption-sedimentary facies, subvolcanic facies and extrusion facies.(3) Three types of eruption——i. e. explosion, effusion and surge.(4) Two kinds of eruptive environments——Subaerial (e. g. volcano in Well Shangshen 3) and subaqueous .(5) Three remarkable volcanic apparatus in Shengping-Wangjiatun area——layered, micro-shield and cone volcanoes according to volcanic processes and lithofacies distribution.

次火山岩有安山玢岩、流纹斑岩、隐爆角砾岩及自碎角砾岩等；(2)火山岩相——通过岩芯观察、镜下鉴定、测井与地震资料解释，营城组火山岩中发育8种岩相类型，即爆发空落相、溢流相、火山碎屑流、基底涌流相、喷发沉积相、火山泥石流相、侵出相和次火山相等；(3)火山喷发的形式——有爆发、溢流和涌流三种；(4)火山喷发环境——有陆上(如尚深3井火山)和水下两种；(5)火山机构类型——根据火山作用特点和岩相分布特征，在升平—汪家屯地区识别出三类截然不同的火山机构，即层火山、微型盾火山和渣锥火山。

Rubber dam laboratory model experiment: respectively measures the reaeration ability of smooth overflow surface and roughened overflow surface, then contrastively analyses the effect and reason of reaeration improving after roughened modification, and the reaeration effect between curve dam and rubber dam.

Study on effect of spillway trough on deposition efficiency of intermittent scouring sand basins;2. Traditional sediment tank has been improved in three aspects by putting an adjusting flow wall in the entrance of water, a spillway trough on spillway crest along the flow direction, redesigning the flush device and an auxiliary fl ush facility.

通过在沉砂池的进水处加调流墙、在溢流堰上沿水流方向设溢流槽、对排砂装置进行改进以及设置辅助冲砂设施三个方面对传统平流式沉砂池进行了改进，设计提出了一种新型平流式沉砂池，可以大大提高沉砂池的沉淀效率，特别是对细颗粒泥砂的沉淀具有很好的效果。

When the flow rate through the Poppet head reaches a certain size, balance piston upper and lower chamber of the two oil pressure difference will create upward hydraulic pressure exceeds the spring preload and balanced piston friction and balance the sum of the piston weight and other forces, balance piston upward, so that the pressure port and overflow port interlinked, a large number of pressure from the oil will flow back into the fuel tank from the overflow port.

当通过提动头的流量达到一定大小时，平衡活塞上、下两腔的油压力差将形成向上的液压力超过弹簧的预紧力和平衡活塞的摩擦阻力及平衡活塞自重等力的总和，平衡活塞上移，使压力口和溢流口相通，大量压力油便由溢流口流回油箱。

Pilot valves and pilot-type relief valves are the main valves of two parts, pilot valves for cone valve, the flow is a small direct action type relief valves.

先导型溢流阀有先导阀和主阀两部分组成，先导阀为一锥阀，实际上是一个小流量的直动型溢流阀。
