摘要： A hydraulic blasting apparatus has an abrasive storage tank disposed operatively between an abrasive recovery tank and a hydraulic pressurized tank. The abrasive storage tank is provided with a first valve openable from the inside of the storage tank to the atmospheric pressure, and also with a second valve to open the connection between the storage tank and the recovery tank and with a third valve to open the connection between the storage tank and the pressurized tank. The pressure in the abrasive storage tank will become the same as the atmospheric pressure by opening the first valve. Next the first and second valve are closed, and after that the third valve is opened so as to drop the abrasive only into the pressurized abrasive tank for a recycle use.

摘要： A powdery material supply valve mechanism including a valve means disposed in front of a piston rod means in a longitudinally aligned relationship with each other, a valve housing means incorporating operatively the valve means and the piston rod means therein and a valve cylinder/piston means. This valve cylinder means is disposed shiftably in the longitudinal direction relative to the valve housing means, and a valve piston means disposed slidably in the bore of the cylinder means along the axis thereof to be urged operatively upon a valve seat of the valve housing means against the resilient force of a valve spring means under the effect of operating fluid pressure fed to the valve cylinder means, while the valve means is opened away from its valve seat with the resilient force of the valve spring means, when the operating fluid pressure is opened to the atmosphere. As the valve piston means stops abutting upon the end wall surface of the valve cylinder means, the current position of the cylinder end wall may determine a current degree of opening of the valve means. This position of the cylinder end wall may be set optionally with an adjustable longitudinal shifting of the valve cylinder means relative to the valve housing means.
摘要翻译：一种粉末材料供给阀机构，包括：阀装置，其设置在彼此纵向对齐的关系中的活塞杆装置的前面;阀门壳体装置，其中可操作地并入阀装置和活塞杆装置;阀体/活塞装置。该阀芯装置相对于阀壳体装置在纵向方向上可移动地设置，以及阀活塞装置，其沿着其轴线可滑动地设置在气缸装置的孔中，以被操作地推压在阀壳体装置的阀座上，当工作流体压力打开时，阀装置在工作流体压力供给到气缸装置的作用下的弹性力，同时阀装置以阀弹簧装置的弹力被打开而远离阀座到大气。当阀活塞装置停止抵接在气缸装置的端壁表面上时，气缸端壁的当前位置可以确定阀装置的当前开度。气缸端壁的该位置可以可选地设置有阀芯装置相对于阀壳体装置的可调节的纵向移位。
