Abstract
本实用新型公开了内置式称重千斤顶新型阀块，它包括安装在每一个内置式称重千斤顶内的阀块，在每个所述的阀块上增设有两个泄油口，将每个内置式称重千斤顶的阀块的泄油口通过泄油回路连接油管依次串联相连，所述的多个内置式称重千斤顶中的第一个或最后一个内置式称重千斤顶的阀块的泄油口与现场液压阀箱相连。本实用新型的内置式称重千斤顶新型阀块，不需要增加现场液压阀箱的数量，泄油回路不需要液压分配器，而且泄油回路液压油管的长度大大缩短，提高了现场液压系统的可靠型和安全性。
The utility model discloses a new valve block of a built-in weighing jack, which includes a valve block installed in each built-in weighing jack, and each valve block is additionally provided with two oil drain ports, and each The oil drain port of the valve block of the built-in weighing jack is sequentially connected in series through the oil drain circuit connection oil pipe, and the drain port of the valve block of the first or last built-in weighing jack among the multiple built-in weighing jacks The oil port is connected with the field hydraulic valve box. The new valve block of the built-in weighing jack of the utility model does not need to increase the number of on-site hydraulic valve boxes, the oil discharge circuit does not need a hydraulic distributor, and the length of the hydraulic oil pipe of the oil discharge circuit is greatly shortened, which improves the reliability of the on-site hydraulic system. type and safety.
Description
技术领域 technical field
本实用新型涉及一种新型内置式称重千斤顶新型阀块，尤其涉及一种大型结构物称重系统用的新型阀块。The utility model relates to a new valve block of a new built-in weighing jack, in particular to a new valve block for a weighing system of a large structure.
背景技术 Background technique
目前，大型结构物称重系统的特点是千斤顶上升时受到结构物的重量作用，系统千斤顶运行速度较慢，下降时在结构油泵共同作用下，运行速度较快，为了调节下降速度，在下降控制回路上安装了调速阀，每个千斤顶阀块的液控单向阀上需要增加一个泄油回路。At present, the characteristic of the large-scale structure weighing system is that the jack is affected by the weight of the structure when the jack rises. The system jack runs at a slow speed, and when it goes down, it runs faster under the action of the structural oil pump. A speed regulating valve is installed on the circuit, and an oil drain circuit needs to be added on the hydraulic control check valve of each jack valve block.
原系统中没有安装调速阀，对下降过程中的速度没法进行控制，没有泄油回路，阀块只有进油和出油两个出口，该阀块不能适应下降过程的调速控制。In the original system, there is no speed regulating valve installed, so the speed during the descending process cannot be controlled. There is no oil drain circuit, and the valve block only has two outlets, the oil inlet and the oil outlet. The valve block cannot adapt to the speed regulation control of the descending process.
