Drilling rig integrated main valve LTZJ-20-10-03B

Uses and FeaturesLTZJ-20/10 series combined multi-way reversing valve is a new generation of products designed and developed by our company for the domestic full hydraulic tunnel drilling rig. The valve inherits the advantages of our company's original tunnel drilling rig combined multi-way reversing valve, and has made great innovation on the basis of our company's original tunnel drilling rig multi-way reversing valve. Compared with the original combined multi-way directional valve for tunnel drilling rig, LTZJ-20/10 series combined multi-way directional valve further reduces the volume, reduces the installation space of hydraulic valve on the host, optimizes the matching characteristics of multi-way valve and host system, optimizes the design of micro-control of each actuator, and changes the auxiliary valve of the original control part to cartridge type, which can make the control points of each mechanism clearer, for the host hydraulic system adjustment provides a convenient.

Drilling rig integrated main valve ZMZJ-00

Uses and FeaturesZMZJ combined multi-way directional valve is my company for the domestic full hydraulic tunnel drilling rig design and development of products. The valve is the first for the full hydraulic tunnel drilling rig hydraulic system integration products. The valve can optimize the complex pipeline in the original hydraulic system, and the host structure is more compact. The valve has compact structure, good fretting performance, low pressure loss, high efficiency of the host system, can realize centralized control, and is more convenient to operate. The valve for the mine under the operation to do the optimization design, in order to eliminate the influence of the working condition environment on the hydraulic valve, our company will ZMZJ-00 designed as a protective combination of multi-way valve, can make the working condition of the environment on the hydraulic system cleanliness to a minimum. ZMZJ-00 multi-way directional valve has obtained the national invention patent. Performance parametersPath（mm）Nominal pressure（Mpa）nominal flow（L/min）Allowable back pressure（Mpa）2531.52502

Drilling rig integrated main valve YZJ-JBD-A

Uses and FeaturesYZJ-00 tunnel drilling rig multi-way valve is my company's independent research and development of the third generation of tunnel drilling rig with valve. The valve has comprehensive functions and simple operation. The clamp and chuck are in a linked state under various working conditions, and the efficiency is obviously improved. On the basis of adding drill pipe after, the original function of adding drill pipe before is created, which is convenient to switch. The built-in balance valve solves the problem of power head sliding down, and the product structure is compact and easy to install.
