Abstract

The invention discloses a kind of three loop logical valves, be provided with valve seat, spool, valve pocket and spring, hydraulic oil can enter from valve seat and valve pocket, under the action of the spring, promotes the motion of spool, realize oil-feed and the difference of oil return circuit of hydraulic oil, improve the flow of convection cell and the control in direction, simple in construction, easy to operate, the problem preferably resolving existence in the past, improve the work efficiency of fluid valve, prepared a kind of three loop logical valves, have well application and promotional value.

Description

A kind of three loop logical valves
Technical field
The invention belongs to control valve for fluids field, particularly relate to a kind of three loop logical valves.
Background technology
In existing fluid control systems, make the control of the two-port valve of pilot control frequently with band Minitype electromagnetic valve Mode, its service behaviour is single, for can realize making the direction of fluid, flow arbitrarily control simultaneously, it is necessary to adopt Control with the pilot valve of different performance, this not only adds the technical difficulty of convection cell Synchronization Control, and make Structure is complicated, the compactest.
Summary of the invention
It is an object of the invention to utilize a kind of three loop logical valves, it is intended to solve present in control valve for fluids Service behaviour is single, it is impossible to make the direction of fluid, flow arbitrarily control simultaneously, and structure is complicated, the compactest Problem.
It is an object of the invention to provide a kind of three loop logical valves, described logical valve includes: valve seat, valve pocket, Spool, spring;Described valve pocket is arranged on described valve seat, and described spool is arranged on described valve pocket, described spring It is arranged on the hollow position of described spool.
Further, described three loop logical valves are by the moving back and forth of spool, it is achieved the oil-feed of hydraulic oil and returning The different circuits of oil.
Further, the described three whole course of action of loop logical valve are divided into two steps: the first step, hydraulic oil is from valve Cover into, promote valve core movement, after overcoming the resistance of spring, enter valve seat, it is achieved unidirectional logical functional oil; Second step, hydraulic oil enters from valve seat, promotes valve core reset, and hydraulic oil is from reserved between valve seat and valve pocket Gap returns to the oil return opening of side, it is achieved original oil-in is not walked in oil return, and from the function of side oil return.
The three loop logical valves that the present invention provides are moved back and forth by spool, change the direction of motion of oil circuit, Three loop logic functions are integrated in one, it is achieved that oil-feed and the different oil circuits of oil return;A whole set of design is completely from specially Based on the demand of equipment, parameter designing is single-minded, and this logical valve also comprises to valve, guiding valve, plug-in mounting form, Compact conformation, it is simple to compact installation, simple in construction, easy to operate, there is good using value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the three loop logical valves that the embodiment of the present invention provides.
In figure: 1, valve seat;2, valve pocket;3, spool;4, spring.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein Instrument, in order to explain the present invention, is not intended to limit the present invention.
Embodiments providing a kind of three loop logical valves, this logical valve includes: valve seat, valve pocket, valve Core, spring;Valve pocket is arranged on valve seat, and spool is arranged on valve pocket, and spring is arranged on the hollow position of spool.
As a prioritization scheme of the embodiment of the present invention, three loop logical valves are moved back and forth by spool, real The oil-feed of existing hydraulic oil and the different circuits of oil return.
Referring to the drawings 1, the embodiment of the present invention three loop logical valve is described in further detail.
As it is shown in figure 1, the three loop logical valves of the present invention are by valve seat 1, valve pocket 2, spool 3,4 groups of spring Becoming, valve pocket 2 is arranged in valve seat 1, and spool 3 is arranged in valve pocket 2, and spring 4 is arranged on spool 3 Hollow position.The three loop logical valves that the present invention provides, whole course of action is divided into two steps: the first step, liquid Force feed enters from valve pocket 2, promotes spool 3 to move, and after overcoming the resistance of spring 4, enters valve seat 1, complete Become the first step, it is achieved unidirectional logical functional oil;Second step, hydraulic oil enters from valve seat 1, promotes spool 3 multiple Position, hydraulic oil returns to the oil return opening of side from gap reserved between valve seat 1 and valve pocket 2, completes second step, Realize oil return and do not walk original oil-in, and from the function of side oil return.
The three loop logical valves that the embodiment of the present invention provides are moved back and forth by spool, change the motion of oil circuit Direction, three loop logic functions are integrated in one, it is achieved that oil-feed and the different oil circuits of oil return;The whole series have designed Complete based on the demand of special equipment, parameter designing is single-minded, and this logical valve also comprises to valve, guiding valve, inserts Dress form, compact conformation, it is simple to compact installation, simple in construction, easy to operate, there is good application valency Value.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention Protection domain within.
