Abstract

The utility model provides a locking loop provided with an electromagnetic directional valve. The locking loop comprises a first oil tank, a hydraulic pump arranged at the top of the first oil tank, a directional valve arranged at the top of the hydraulic pump, a hydraulic cylinder arranged at the top of the directional valve and connected through two correspondingly arranged oil lines, a piston arranged in the hydraulic cylinder as well as a first check valve and a second check valve which are arranged on a loop between the directional valve and the hydraulic cylinder, wherein the directional valve adopts the electromagnetic directional valve, and a third oil tank for containing oil on an oil return line is arranged at the bottom of the directional valve. The locking loop provided with the electromagnetic directional valve is reasonable in design, firm in structure, reliable in operation, high in work efficiency, convenient to operate and safe to use, and reduces potential safety hazards.

Description

With the locking loop of solenoid directional control valve
Technical field
The utility model relates to hydraulic equipment, especially with the locking loop of solenoid directional control valve.
Background technique
In hydraulic system, the startup of operation mechanism, to stop or converting moving direction etc. be all to utilize to control to enter the switching of element liquid stream and change flow direction to realize.The loop of realizing these functions is called direction control circuit, so-called direction control circuit mainly comprises commutation loop and locking loop, wherein locking loop is to make oil hydraulic cylinder upper stop at an arbitrary position, and the loop of mobile position under external force not after stopping, it is not Tai Gao or the occasion that only needs of short duration locking that some locking loops of commonly using at present can only be suitable for locking requirement, the machinery such as engineering machinery and lifting machine that is not suitable for higher locking requirement uses, in order to make to lock the more effective work of loop energy, conventionally all can on loop, be provided with selector valve, but most selector valve is all hydraulicchange-over valve, structure is not very stable, adaptive capacity is not strong, it is not very convenient using.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good airproof performance, the fast locking loop with solenoid directional control valve of reaction velocity.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: with the locking loop of solenoid directional control valve, comprise the first fuel tank, be located at the first top of oil-tank oil hydraulic pump, be located at oil hydraulic pump top selector valve, be located at selector valve top and oil hydraulic cylinder that oil circuit connects be set, be located at the piston in oil hydraulic cylinder and be located at selector valve the first one-way valve, the second one-way valve on loop between oil hydraulic cylinder by two correspondences, described selector valve is solenoid directional control valve, and the bottom of selector valve is provided with the 3rd fuel tank for reinstalling the fluid on oil circuit.
As preferably, between described oil hydraulic pump and selector valve, be provided with relief valve, a side connection of relief valve arranges the second fuel tank, unnecessary fluid can be emitted by relief valve, is stored in the second fuel tank, effectively alleviates the pressure on loop.
Beneficial effect:
The utility model has adopted technique scheme that the locking loop with solenoid directional control valve is provided, and has made up the deficiencies in the prior art, reasonable in design, sound construction, and reliable operation, working efficiency is high, easy to operate, reduces potential safety hazard, uses safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, with the locking loop of solenoid directional control valve, comprise the first fuel tank 1, be located at the oil hydraulic pump 2 at the first fuel tank 1 top, be located at the selector valve 3 at oil hydraulic pump 2 tops, be located at selector valve 3 tops, by two correspondences, the oil hydraulic cylinder 4 that oil circuit connects be set, be located at the piston 10 in oil hydraulic cylinder 4 and be located at selector valve 3 and oil hydraulic cylinder 4 between the first one-way valve 5 on loop, the second one-way valve 6, described selector valve 3 is solenoid directional control valve, the bottom of selector valve is provided with the 3rd fuel tank 9 for reinstalling the fluid on oil circuit, between described oil hydraulic pump 2 and selector valve 3, be provided with relief valve 7, one side connection of relief valve 7 arranges the second fuel tank 8.
When real work, when selector valve 3 is in left when position, pressure oil enters the left chamber of oil hydraulic cylinder 4 through the first one-way valve 5, drive pressure oil to do movement from left to right by piston 10, in mobile process, open the second one-way valve 6, treated high pressure oil is led directly to the 3rd fuel tank 9 by the right chamber of oil hydraulic cylinder 4, in the time that piston 10 moves to oil hydraulic cylinder 4 low order end, selector valve 3 moves to right position, the direction that oil hydraulic cylinder 4 inner carriers 10 move changes, pressure oil enters the right chamber of oil hydraulic cylinder 4 by the second individual event valve 6, be drained in the 3rd fuel tank 9 by the left chamber of oil hydraulic cylinder 4 through processing, while having arrived the position of this stop, as long as make selector valve 3 in meta, because the Median Function of selector valve 3 is H type, high pressure oil leads directly to the 3rd fuel tank 9, pilot pressure disappears immediately, the first one-way valve 5 and no longer two-way admittance of the second one-way valve 6, oil hydraulic cylinder bidirectional locking.Good seal performance, reliable lock, compression resistance is strong, easy to use.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
