Abstract
The utility model discloses an electromagnetic safe unloading valve for a self discharging automobile, which is characterized in that the check one-way valve (2), the main conical valve (10) and the guide conical valve (7) of a system are inserted and installed on one valve body. The valve can be directly installed on the flange of the oil outlet of a hydraulic oil pump by connecting screws to cause the pump and the valve to be integrated to form an integral body. The valve directly utilizes the operation of a direct current (or alternate current) wet electric magnet (1) to control the system to increase pressure and decrease pressure. The pressure size of the system is regulated by a pressure regulating shim (4). The electromagnetic safe unloading valve for a self discharging automobile can thoroughly change the control mode of a self discharging automobile and the layout mode of the whole system. The electromagnetic safe unloading valve for a self discharging automobile furthest improves the integrated level of the hydraulic system of the self discharging automobile.
Description
The utility model relates to dump truck hydraulic control valve element.
At present, known both at home and abroad dump truck control valve system all contains the simple directly manual operation valve of ejector half safety valve by non-return one-way valve, guiding valve or rotary valve type and forms, mainly contain following shortcomings in actual use: the one, each control valve and oil pump all are elements independently one by one, their connections to each other can only be connected by flexible pipe or hard tube, so not only increased interelement pipe fitting and flange quantity and made assembling difficulty more, simultaneously, make the level of integration of whole system reduce the increase maintenance difficult; The 2nd, because of valve is manual direct manipulation, in the narrow operator cabin of automobile, just had more the mechanical linkage between a Joystick and Joystick and the valve, thereby make the layout of automobile cab not attractive in appearance, driver's manipulation strength strengthens, and the mounting point of valve and corresponding oil pipe is subjected to great limitation; The 3rd, because the volume of each control valve is bigger, the weight of system has correspondingly also increased many, in addition because this system has used a simple straight ejector half safety valve pilot pressure, the noise of system under overfall working condition is very big like this, make working environment more abominable, also make the idle energy consumption of automobile strengthen because the deadweight of hydraulic system increases; The 4th, the structure of non-return one-way valve strengthens the oil pressure loss of system, all use guiding valve or rotary valve structure because of handling main valve on the other hand, so not only make valve easily be caused operating difficulties in use by some minute impurities " stuck ", simultaneously because the restriction of structural type also makes the internal leakage of valve, the pressure loss all very big, the life-span is also very short.
The purpose of this utility model just is to overcome the deficiency of above-mentioned dump truck control valve system, and the Electromgnetic seat unloading valve of the integrated control of a kind of high integration "--liquid " is provided.
The new purpose of this practicality is achieved in that
Dump truck Electromgnetic seat unloading valve, it mainly is made up of elements such as direct current (interchange) wet electro-magnet, spring seat, pressure regulation pad, guide sleeve, pressure adjusting spring, pilot poppet valve, valve seat, main spool spring, main coning valve, valve body, non-return one-way valves, it is characterized in that: 1, this valve is inserted into non-return one-way valve, main coning valve and the pilot poppet valve of system on the valve body, and valve directly can be installed on the oil outlet flange of hydraulic-pressure pump by joint bolt, pump valve is integrated in one; 2, this valve directly utilizes the boosting and step-down of motion control system of direct current (interchange) wet electro-magnet, and the size of system pressure is adjusted by the pressure regulation pad.
Described pilot poppet valve, main coning valve, non-return one-way valve are cone valve structure.
Dump truck Electromgnetic seat unloading valve is guide's overflow pattern.
Effect of the present utility model is:
It has thoroughly changed the maneuverability pattern of dump truck and the setting type of whole system, make the hydraulic system of dump truck integrated to greatest extent, make the design of automobile more attractive in appearance, realize " electricity-liquid " integrated control of dump truck, thoroughly alleviated operator and installation, maintenance personnel's labor intensity and working environment.Owing to use the system of this valve to deduct pump and valve in the past, interelement oil pipe and the flanges of connecting such as valve and valve, thus reduced cost.Particularly generally on vehicle frame, all be provided with a stroke limit valve that plays protective gear for large-tonnage dump truck system; then only need to control the break-make of power supply behind use the utility model, realize the operating mode protection of former stroke valve with a simple electrical trip switch.
Description of drawings:
Fig. 1 is an Electromgnetic seat unloading valve cut-away view.
Fig. 2 is the outside connection form figure that installs of Electromgnetic seat unloading valve.
Be described further below in conjunction with accompanying drawing:
At first with this valve with four screw attachment on the oil outlet flange of oil pump, during work from the oil-feed of P mouth, P
1Mouth connects operating cylinder, T mouth connected tank or be attempted by on the filler opening position of oil pump, under the situation of oil pump feed, if electromagnet (1) energising, then electromagnet push-rod is depressed pressure adjusting spring (6) and is remake and be used on the pilot poppet valve (7), then main coning valve (10) is closed under the pressure oil effect, and come oil push non-return one-way valve (12) to enter P from pump this moment
1The work of confession operating cylinder.If the load of operating cylinder surpasses the set pressure in advance of this valve, then the fluid of superpressure is pushed pilot poppet valve (7) open, makes main coning valve (10) action then, makes superpressure fluid flow back to fuel tank through main coning valve (10) by the T mouth, guarantees the safety of work system.If electromagnet (1) outage, then pressure oil is pushed pilot poppet valve (7) open and is made main coning valve (10) unlatching, and this moment, the oil that comes from oil cylinder and oil pump flowed back to fuel tank by the T mouth of this valve, made the whole system off-load.At oil pump not under the situation of fuel feeding, if electromagnet (1) energising, then main coning valve of this valve (10) and pilot poppet valve (7), non-return one-way valve (12) Close All, the fluid that returns in the oil cylinder can't return fuel tank, then oil cylinder just by constant a definite position.If electromagnet (1) outage, then pilot poppet valve (7) is opened, and main coning valve (10) is also opened then, from oil cylinder come oil just can be in main coning valve (10) the direct oil sump tank of T mouth of this valve, make whole system be in unloading condition.Because the action of oil cylinder is the action of railway carriage, therefore, the operating mode of above-mentioned valve control oil cylinder has just determined that also the railway carriage of dump truck lifts action overall processes such as opening, stop, returning on dumping car.
