Abstract
The utility model relates to a throttle valve of a hydraulic control filling material conveying. The throttle valve is characterized in that an oil cylinder is arranged in a throttle valve body, and the throttle valve body is sequentially provided with a piston, a piston rod and a valve core from top to bottom, the side wall of the oil cylinder is provided with an oil cylinder oil inlet and an oil cylinder oil outlet, the lower part of the oil cylinder is connected with a middle pipe opening of a throttle tee-joint, other pipe openings of the throttle tee-joint are connected with a working pipe through flanges, the throttle tee-joint is provided with a dry oil injection opening, the oil cylinder oil inlet and the oil cylinder oil outlet are respectively connected through an oil pipe and a hydraulic station, the upper part of the oil cylinder is provided with a displacement sensor which is connected with an outer electric control system, and the displacement sensor is connected with a cylinder drum flange through an inner hexagonal screw. The throttle valve disclosed by the utility model is hydraulically driven, accurately controls the flow rate of the working pipe by the displacement sensor, has the characteristics of high safety, accurate control, high action speed, capability of realizing remote control and linkage with other valve bodies of pipes, and is mainly beneficial to monitoring on the working state of the whole system.
Description
Technical field
the utility model relates to a kind of throttle valve, particularly relates to a kind of hydraulic control that is used for the control of paste body filling Flow-rate adjustment and carries casting resin to use throttle valve, belongs to filling in mine mining technique field.
Background technique
traditional throttle valve adopts machinery and electromagnetic mode to drive more.Mechanical Driven mode automaticity is low, task difficulty is big, operator's technical merit is had relatively high expectations, and pipeline is arranged under the mine more, increases to go into the well person-time, is not easy to timely and effective controlling plumbing fixtures flow.Though electromagnetic drive mode can be realized telecontrol, possibly cause spark, potential safety hazard is arranged, be not suitable for Minepit environment.So, the mining industry be badly in need of a kind of automaticity higher, can realize telecontrol, adapt to mine operating mode and safe and reliable throttle valve.
Summary of the invention
The purpose of
the utility model just is to overcome the above-mentioned deficiency that existing technology exists, and can't satisfy the filling in mine demand and provides a kind of hydraulic control to carry casting resin to use throttle valve for solving existing throttle valve.The utility model uses hydraulic driving; Flow through the accurate Control work pipeline of displacement transducer; Have safety, control accurately, be swift in motion, can realize telecontrol, with the characteristics of other valve bodies interlocks of pipeline, most importantly help monitoring to the whole system working state.
technological scheme that the utility model adopted is: this hydraulic control carries casting resin to use throttle valve; Include throttle valve body, oil cylinder, throttling threeway, spool; Be characterized in being provided with oil cylinder in the throttle valve body, and be provided with piston successively from top to bottom, piston rod and spool, also be provided with oil cylinder filler opening, oil cylinder oil outlet on the sidewall of oil cylinder; The oil cylinder bottom is connected with the intervalve crossing of throttling threeway; Two line portals of other of throttling threeway are connected with service pipe through flange, and throttling threeway place is provided with the drier oil pouring orifice, and said oil cylinder filler opening, oil cylinder oil outlet are connected with hydraulic station through oil pipe respectively; The top of oil cylinder is provided with the displacement transducer that is connected with the external electrical control system, and this displacement transducer is connected through between socket head screw and the cylinder barrel flange.
for accomplishing the purpose of the utility model better, the utility model adopts packing ring and seal ring double sealing protective measures at the threeway and the spool place of valve body, effectively stops pipeline medium to get into oil cylinder, prevents the wearing and tearing of piston rod and oil cylinder inner wall.
compared with prior art; The beneficial effect of the utility model is: the utility model uses hydraulic driving; Flow through the accurate Control work pipeline of displacement transducer; Have safety, control accurately, be swift in motion, can realize telecontrol, with the characteristics of other valve bodies interlocks of pipeline, most importantly help monitoring to the whole system working state.
