Abstract
The invention discloses an equivalent cylinder device which comprises a cylinder body, wherein two ends of the cylinder body are respectively provided with an end cover; a piston is arranged in the cylinder body and provided with two opposite check valves; and two ends outside the cylinder body are respectively provided with a magnetic switch for converting the positions of the pistons into corresponding switching current signals. The device has simple and compact structure, low noise, easy maintenance and convenient mounting and can be widely applied to the industries of ship matching, petroleum, chemical engineering, and the like.
Description
Technical field:
The present invention relates to a kind of valve switch position indicator.
Background technique:
Existing valve switch position 5 devices owing to reasons such as structures, are installed inconvenience, complex structure, use in the deathtrap to have potential safety hazard.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, compact, the equivalent cylinder device of favorable working performance.
Technical solution of the present invention is:
A kind of equivalent cylinder device, it is characterized in that: comprise cylinder body, the cylinder body two ends are provided with end cap, and piston is set in the cylinder body, two one-way valves in opposite directions are set on the piston, a magnetic switch that piston position is converted into the respective switch current signal are set respectively at two ends, the cylinder body outside.
On the end cap of two ends, be provided with one respectively and stretch into the adjustable screw that plays position-limiting action in the cylinder body, to piston.
The present invention is simple in structure, compact, noise is low, easy care, easy for installation, can be widely used in industries such as boats and ships are supporting, oil, chemical industry.
When the present invention uses, do not need the hydraulic valve telechirics that extra power source is provided, it is connected in the hydraulic system with the valve that surges, utilize the piston in the pressure-driven equivalent cylinder device of system itself, with the valve that surges do equate the motion, when valve closing or when opening, the corresponding position of piston arrives, two outer magnetic switchs of equivalent cylinder can be converted into piston position corresponding open and close current signal.
The present invention can be installed in away from the position of deathtrap and come indicating valve gate switch signal, and valve can come indicating valve gate switch signal in the position of deathtrap, and valve can be worked in deathtrap (immersion liquid or explosion-proof area etc.) normally, has fundamentally solved the drawback that hydraulic operated valve gate switch indicating device in the past can not be worked in the deathtrap.The piston of equivalent cylinder is provided with two one-way valves in opposite directions simultaneously, air during debugging in the cylinder body can be got rid of smoothly by hydraulic pipe line, two adjusting screw can significantly reduce the workload in the debugging by these structures according to the mobile position of actual conditions regulating piston.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is a user mode fundamental diagram of the present invention.
Embodiment:
A kind of equivalent cylinder device, comprise cylinder body 1, the cylinder body two ends are provided with end cap 2,3, and piston 4 is set in the cylinder body, two one-way valves 5,6 in opposite directions are set on the piston, a magnetic switch 7,8 that piston position is converted into the respective switch current signal are set respectively at two ends, the cylinder body outside.
On the end cap of two ends, be provided with one respectively and stretch into the adjustable screw 9,10 that plays position-limiting action in the cylinder body, to piston.
Claims (2)
1. equivalent cylinder device, it is characterized in that: comprise cylinder body, the cylinder body two ends are provided with end cap, and piston is set in the cylinder body, two one-way valves in opposite directions are set on the piston, a magnetic switch that piston position is converted into the respective switch current signal are set respectively at two ends, the cylinder body outside.
2. equivalent cylinder device according to claim 1 is characterized in that: be provided with one respectively and stretch into the adjustable screw that plays position-limiting action in the cylinder body, to piston on the end cap of two ends.
