JLD型系列液压阀门测试台是集机电、液压、试压液体介质贮存循环使用于一体，具有功能完善、性能稳定、自动化程度高等特点。试压全过程由液压传动，电器控制，对被测阀门施加无任何附加影响试验结果的外力，广泛应用于公称通径DN50-DN3000mm的法兰式、对夹式结构，高、中、低压蝶阀、对夹式止回阀和刀型阀等阀门的密封和强度等各项性能测试。zui高密封实验压力10.0MPa，强度16.0MPa。
JLD型液压蝶阀阀门测试台，采用以被试阀门法兰端面做定位密封，由液压油缸往复驱动工作被试工件进行压紧。为了尽量减少外力的影响，压紧油缸输出压力在（3.0-30.0MPa）压力等级随意控制增压调节选择，使被试阀门在不同通径和不同压力下进行阀门试验。多只轴向压紧油缸的只径向进退移动，采用一直油缸往复驱动实现，连杆原理了传动了多只轴向夹紧油缸同步移动。

JLD series hydraulic valve testing bench is a set of mechanical, hydraulic, pressure test liquid media storage cycle used in one, with perfect function, stable performance, high degree of automation. Pressure test process consists of hydraulic transmission, electrical control, on the tested valve applied without any additional influence the test results and external force, widely used in nominal diameter DN50-DN3000mm flange type, on the folder type structure, high, in, the low-pressure valve, wafer type check back valve, knife type valve, the valve seal and strength etc. the performance test. Highest sealing test pressure 10.0MPa, strength 16.0MPa.
JLD type hydraulic butterfly valve test bench, used to test the valve flange end face to do the positioning and sealing, by the hydraulic cylinder reciprocating drive work to carry out the work of pressing. In order to minimize the impact of external pressure, the pressure cylinder output pressure in the (3.0-30.0MPa) pressure level to control the choice of pressurization, so that the valve under different sizes and pressure to carry out the valve test. Multi axial pressing oil cylinder only radial move forward and backward, has been to use reciprocating cylinder drive, a connecting rod mechanism of the transmission of the multi axial clamping oil cylinder move synchronously.
