JWZ型臥式液壓閥門測試臺，分為液壓系統(tǒng)、電氣系統(tǒng)、機(jī)械系統(tǒng)、測壓系統(tǒng)等四大系統(tǒng)，由機(jī)架、左右工作盤、夾緊油缸、牽引油缸、翻轉(zhuǎn)油缸、移動油缸、試驗(yàn)介質(zhì)控制管路及控制閥、低壓水泵、高壓水泵、油泵及電機(jī)、試驗(yàn)介質(zhì)控制管路及控制閥、液壓控制系統(tǒng)、電氣控制系統(tǒng)、試驗(yàn)壓力計(jì)量等組成。
閥門的裝夾型式為抱壓式，被測閥門的兩端法蘭和盲板，分別由左右工作盤上的夾爪抱壓夾緊，右工作盤在翻轉(zhuǎn)油缸作用下，可以90°翻轉(zhuǎn)，以便在進(jìn)行密封試驗(yàn)時(shí)觀察和檢查密封泄漏情況，工作盤上的壓爪在徑向上根據(jù)閥門法蘭大小，在牽引油缸的作用下可同步張大和縮小，在軸向上根據(jù)閥門法蘭厚度，在夾緊油缸作用下可同步壓緊和放松，左向工作盤可根據(jù)閥門結(jié)構(gòu)長度長短，在移動油缸作用下可以左右移動，低壓水泵和介質(zhì)循環(huán)水箱系統(tǒng)組成一體，使介質(zhì)循環(huán)使用，壓力表控制閥門和電器按鈕開關(guān)，全部設(shè)計(jì)在測試臺前方進(jìn)行操作控制，能使各機(jī)制協(xié)調(diào)動作，操作方便，安全可靠，滿足廣大用戶測試需要。

valve test bench
JWZ type horizontal hydraulic valve testing bench, hydraulic system, electrical system, mechanical system, pressure system of the four systems, composed of a frame, the left and the right working disk, the clamping oil cylinder, traction oil cylinder, the turning oil cylinder, a moving oil cylinder and the test medium control pipeline and a control valve, low pressure water pump, high pressure water pump, oil pump and motor, test medium control pipeline and a control valve, hydraulic control system, electrical control system, the test pressure measurement.
The clamping valve type for holding type, both ends of the flange and the blind plate valve measured, respectively by clamping jaw working disk holding pressure clamping, right working disk in the turning cylinder under the action of 90 degree turn, in order to seal test to observe and check the seal leakage, work pressure claw plate in the radial direction of the valve flange according to the size of the traction under the action of the oil cylinder can be synchronized wide and narrow, in the axial direction according to the valve flange thickness, the clamping cylinder under the action of synchronous compression and relaxation, disk can be left to work according to the length of the valve structure length, can move around in the cylinder under the action of high pressure water pump and medium circulation water tank system development, make the medium cycle use, pressure gauge control valves and electric button switch, designed for operation control on the test bench in front of, can make the transfer mechanism of CO The operation is convenient, safe and reliable, and meets the needs of user testing.
