Abstract
The utility model is a kind of two four-way hydraulic operated valves, comprises valve body, piston, feedback switch.Piston is positioned at the valve pocket of valve body.The inwall of valve body caves inward, and is divided into different cavitys by piston space.Cavity is respectively at the longitudinal hole UNICOM of valve body.Feedback switch installs the end with valve body.The utility model provide a kind of entirely board-like, without spring, differential pressure action two four-way hydraulic operated valves with position switch, the pipe free modularization that can realize speed regulator HYDRAULIC CONTROL SYSTEM valve group is integrated, its position signal of Real-time Feedback, without impacting, switching oil circuit reliably.
Description
Technical field:
The utility model relates to a kind of without pipe connection control hydraulic operated valve.
Background technique:
The Highgrade integration of hydrogovernor hydraulic system requires day by day to improve, need to realize all leading type control valve groups can pipe free integrated.
Existing two four-way hydraulic operated valves do not have complete board-like connection and with position feedback and the combination function of hydraulic reposition, cannot realize above-mentioned integrated requirement.
Summary of the invention:
The utility model provide a kind of entirely board-like, without spring, differential pressure action two four-way hydraulic operated valves with position switch, the pipe free modularization that can realize speed regulator HYDRAULIC CONTROL SYSTEM valve group is integrated, its position signal of Real-time Feedback, without impacting, switching oil circuit reliably.
The technical solution adopted in the utility model is: by valve body (1), piston (2), feedback switch (3), piston (2) is positioned at the valve pocket of valve body (1), the inwall of valve body (1) caves inward, and be partitioned into different cavitys by piston (2), cavity respectively with the longitudinal hole UNICOM of valve body, feedback switch (3) is arranged on the end of valve body (1).
The utility model has the advantage of:
1) adopt full subplate mounting valve body to realize valve group and realize module integration without when any external pipeline.
2) adopt and can to realize without the differential pressure control action piston of spring that reliability that valve group switches and quick-action are also effective to be reduced action and impact.
3) adopt induction type proximity switch to realize the resistance of its valve element position and can feed back valve location status timely rapidly.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model device.
Embodiment:
Two the four-way hydraulic operated valves of one as shown in Figure 1.Comprise valve body 1, piston 2, feedback switch 3.Piston 2 is positioned at the valve pocket of valve body 1.The inwall of valve body 1 caves inward, and is partitioned into different cavitys by piston 2.Cavity is respectively at the longitudinal hole UNICOM of valve body.Feedback switch 3 installs the end with valve body 1.
When valve working, piston 2 is steady state value compared with the hydraulic coupling of small size side, and the hydraulic coupling can being changed piston 2 larger area side by the control oil switching hydraulic operated valve control chamber is greater than or less than the hydraulic coupling compared with small size side thus realizes the quick and stable commutation of valve.
When the larger area side of the piston 2 of valve moves to the induction type feedback switch 3 being arranged on valve body 1 end, switch can send actuating signal, otherwise when the induction type feedback switch being arranged on valve body 1 end is left in the larger area side of piston 2, switch resets, thus realizes the feedback of valve state.
Claims (1)
1. two four-way hydraulic operated valves, it is characterized in that: be made up of valve body (1), piston (2), feedback switch (3), piston (2) is positioned at the valve pocket of valve body (1), the inwall of valve body (1) caves inward, and be partitioned into different cavitys by piston (2), cavity respectively with the longitudinal hole UNICOM of valve body, feedback switch (3) is arranged on the end of valve body (1).
