Abstract
The utility model discloses a hydraulic built-in upper controlled discharging device for tank wagon, of which the structure consists of a tank body, an oil cylinder sleeve, pressing springs, a valve stem push-pull oil cylinder, a valve stem, a valve piston and a valve base and is characterized in that the oil cylinder sleeve is fixed on a top part of the oil tank body, the pressing springs and the valve stem push-pull oil cylinder are fixed between spring brackets which have upper parts connected with the oil cylinder sleeve and lower parts connected by the valve stem with the valve piston arranged on the valve base, the valve base is fixed on a bottom part of the tank body. Compared with the prior art, the hydraulic built-in upper controlled discharging device for tank wagon has the advantages of reasonable design, a simple structure, high automation and convenient operation and use, and is capable of lowering labor intensity and eliminating wasting of resources caused by flowing, splashing, dripping and leaking of materials; thereby the utility model has a relatively good promotion and use values.
Description
The utility model relates to a kind of tank wagon retrofit technology, the built-in upper control mode drawing mechanism of specifically a kind of tank wagon hydraulic pressure.
Along with development and national economy, the kind of special-use vehicle is more and more abundanter, and the kind of material that tank wagon is transported is more and more, and capacity is also increasing.The high capacity motor tank tuck is in order to increase work efficiency, and often is equipped with the pipeline system that stimulates the menstrual flow greatly, and the volume of its switch valve is also very big, particularly when fortune material is the bigger fluid of viscosity, because of bonding makes the craft keying of valve difficult more.When fortune material need be incubated, the manual application that opens and closes traditional drawing mechanism of external valve, many because of its heat dissipation capacity, crack force is big, valve arrangement is difficult is subjected to bigger restriction.In use existing deficiency is, opens and closes very difficulty of operation by hand, and leakproofness is poor, and the evaporating, emitting, dripping or leaking of liquid or gas phenomenon happens occasionally, and not only causes the waste of raw material, but also leakage that can raw material causes gross pollution to environment.
The purpose of this utility model provides a kind of built-in upper control mode drawing mechanism of tank wagon hydraulic pressure that can handle its keying in operator's compartment.
The purpose of this utility model realizes in the following manner, change into the big caliber valve of external built-in, adopt the keying that is connected machinery control valve plug of hydraulic ram and valve rod, in order to guarantee the normally off of valve plug, add pressing spring at the cylinder body of hydraulic ram and the two ends of piston by spring bracket, valve plug is in all the time has densification to close state, in the time of need opening the valve discharging, operating personal starts the hydraulic ram master cock that is located in the operator's compartment, hydraulic ram work pulling valve rod could be opened valve plug, the primer fluid compressing cylinder resets after the discharging, valve plug close under the dual thrust of hydraulic ram and spring keep and valve seat between airtight.
Figure of description is the structural representation of the built-in upper control mode drawing mechanism of tank wagon hydraulic pressure.
With reference to Figure of description to hydraulic built-in upper controlled discharging device for tank wagon of the present utility model do with Under explain.
Hydraulic built-in upper controlled discharging device for tank wagon of the present utility model, its structure are by tank body 1, oil Cylinder sleeve 2, pressing spring 3, valve rod push cylinder 4, spring support 5, valve rod 6, valve plug 7, valve seat 8 structures Become, cylinder sleeve 2 is fixed on the top of tank car tank body 1, and pressing spring 3 and valve rod push cylinder 4 are fixed on bullet Between the spring bracket 5, the upper end of spring support 5 and cylinder sleeve 2 join, and valve is passed through in the lower end of spring support 5 Bar 6 be arranged on that valve plug 7 joins on the valve seat 8, valve seat 8 is fixed on the bottom of tank body 1.
The top of valve seat 8 is provided with valve rod support 9 and stem guiding cover 10, and stem guiding cover 10 is passed in the lower end of valve rod 6 and valve rod support 9 joins with valve plug 7, and the below of valve seat 8 is connected to discharge duct 11.
Embodiment:
The processing and fabricating of each parts of the built-in upper control mode drawing mechanism of tank wagon hydraulic pressure of the present utility model can get final product by processing shown in traditional sheet metal rivet welding technology by specification accompanying drawing.
The description of operation of the built-in upper control mode drawing mechanism of tank wagon hydraulic pressure of the present utility model is as follows: vehicle is in transportation, under the combined action of valve plug valve rod push cylinder and holddown spring, be pressed in reposefully on the valve seat to guarantee the leakproofness of valve with certain pressure.When needs carry out discharging, start the master cock that is located in the operator's compartment and start the work of valve rod push cylinder, move on the pulling valve rod, overcome the application force of holddown spring, make the valve plug upward movement, begin discharging gradually.After discharging finishes, open valve rod push cylinder master cock, valve rod push cylinder and holddown spring combined action promote valve plug and move downward, and be pressed in reposefully on the valve seat with certain pressure in valve rod, finish discharge operation.
The built-in upper control mode drawing mechanism of tank wagon hydraulic pressure of the present utility model is compared with prior art, and advantage is: can handle the keying that the valve rod push cylinder is finished valve, the labour intensity that reduces a staff in operator's compartment.Valve arrangement is in the inside of tank body, can reduce thermal loss and cross the cold line clogging that causes because of valve.Built-in valve design novelty, arrangement convenience, it is less to be specially adapted to the tank body lower space, the situation of the built-in lower controlling type drawing mechanism of hydraulic pressure difficult arrangement.Have reasonable in design, simple in structure, be easy to process, easy for operation, stop material because of the wasting of resources that evaporating, emitting, dripping or leaking of liquid or gas caused with to the characteristics such as pollution of environment, thereby, have good value for applications.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
