JLD型系列液壓閥門測試臺是集機(jī)電、液壓、試壓液體介質(zhì)貯存循環(huán)使用于一體，具有功能完善、性能穩(wěn)定、自動化程度高等特點。試壓全過程由液壓傳動，電器控制，對被測閥門施加無任何附加影響試驗結(jié)果的外力，廣泛應(yīng)用于公稱通徑DN50-DN3000mm的法蘭式、對夾式結(jié)構(gòu)，高、中、低壓蝶閥、對夾式止回閥和刀型閥等閥門的密封和強(qiáng)度等各項性能測試。最高密封實驗壓力10.0MPa，強(qiáng)度16.0MPa。

JLD型液壓蝶閥閥門測試臺，采用以被試閥門法蘭端面做定位密封，由液壓油缸往復(fù)驅(qū)動工作被試工件進(jìn)行壓緊。為了盡量減少外力的影響，壓緊油缸輸出壓力在（3.0-30.0MPa）壓力等級隨意控制增壓調(diào)節(jié)選擇，使被試閥門在不同通徑和不同壓力下進(jìn)行閥門試驗。多只軸向壓緊油缸的只徑向進(jìn)退移動，采用一直油缸往復(fù)驅(qū)動實現(xiàn)，連桿原理了傳動了多只軸向夾緊油缸同步移動。

JLD series hydraulic valve test 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.
