Abstract
The utility model provides a compact-structure accelerating loop. The compact-structure accelerating loop is characterized by comprising a hydraulic pump connected with an oil tank, the hydraulic pump is connected with a reversing valve which is connected with a piston chamber of an accelerating cylinder, and a right chamber of the accelerating cylinder is connected to the oil tank via the reversing valve. The compact-structure accelerating loop is reasonable in design, compact in structure, convenient to operate, simple to control and good in working efficiency.
Description
Technical field
The utility model relates to the hydraulics field, is specifically related to the speed accelerating circuits of compact structure.
Background technique
Because the hydraulic actuator volume is little, lightweight, compact structure, stable working, reaction is fast, be easy to realize quick startup, braking and the advantage such as commutation frequently, be widely used in machine-building, engineering construction, petrochemical industry, communications and transportation, the All aspects of such as military machine, existing cylinder speed accelerating circuits complex structure, arrange trouble, operating difficulties, work stable not, economic benefit is not high, can not satisfy the demands, because the shortcoming of above-mentioned instrument, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, be engaged in this industry working experience for many years with it, and then develop the speed accelerating circuits of compact structure, utilize simple design, can make the utility model reach the effect of easy to operate and working stability.
Summary of the invention
Technical problem to be solved in the utility model is to provide the speed accelerating circuits of compact structure, reasonable in design, and compact structure is easy to operate, controls simply good working effect.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the speed accelerating circuits of compact structure, it is characterized in that: comprise and be connected the oil hydraulic pump arranged with fuel tank, described oil hydraulic pump is connected with selector valve, described selector valve is connected with the speed-up cylinder piston cavity, and the right chamber of described speed-up cylinder is connected to fuel tank through selector valve.
As preferably, be connected with sequence valve between described selector valve and speed-up cylinder, described sequence valve is connected setting with the left chamber of speed-up cylinder.By adopting this set, can control the sequentially-operating of a plurality of elements, guarantee the steady of work.
As preferably, described sequence valve is connected setting with fuel tank.By adopting this set, facilitate pressure regulation, guarantee normally carrying out of work.
As preferably, described oil hydraulic cylinder is connected with one-way valve on left chamber, and described one-way valve is connected with fuel tank.By adopting this set, oil only flows towards a direction, can prevent oily reverse flow, has avoided oil leakage phenomenon.
Beneficial effect:
The utility model adopts technique scheme that the speed accelerating circuits of compact structure is provided, and has made up the deficiencies in the prior art, has improved working efficiency, has improved economic benefit, reasonable in design, and compact structure is easy to operate, controls simply good working effect.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the speed accelerating circuits of compact structure comprises and is connected the oil hydraulic pump 2 arranged with fuel tank 1 that described oil hydraulic pump 2 is connected with selector valve 3, and described selector valve 3 is connected with speed-up cylinder piston cavity 5, and the right chamber 6 of described speed-up cylinder is connected to fuel tank 1 through selector valve 3.Be connected with sequence valve 7 between described selector valve 3 and speed-up cylinder 4, described sequence valve 7 is connected setting with the left chamber 8 of speed-up cylinder.Described sequence valve 7 is connected setting with fuel tank 1.Described speed-up cylinder is connected with one-way valve 9 on left chamber 8, and described one-way valve 9 is connected with fuel tank 1.
During real work, when the left position of selector valve 3 is linked in loop, oil enters speed-up cylinder piston cavity 5 through the through hole of speed-up cylinder 4, and piston is stretched out fast, and the required oil in the left chamber 8 of speed-up cylinder sucks from fuel tank 1 through one-way valve 9, piston moves right, when piston promotes to be arranged on the workpiece on piston right side, because load strengthens, pressure raises, opening sequence valve 7, high pressure oil enters the left chamber 8 of speed-up cylinder closing one-way valve 9 simultaneously; When the right position of selector valve 3 is linked in loop, oil enters the right chamber 6 of speed-up cylinder, opens one-way valve 9 simultaneously, and the oil return in the left chamber 8 of speed-up cylinder flows back to fuel tank 1, and piston is return left fast.Make up the deficiencies in the prior art, improved working efficiency, improved economic benefit, reasonable in design, compact structure, easy to operate, control simply good working effect.
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.
