Abstract
The utility model discloses a practical and reliable device for detecting a valve position of a hydraulic valve. A valve rod of the valve drives a valve detection connecting rod to rotate around a fixed rotating shaft, so that a mercury switch is opened or closed; and the opening or closing state of the valve position of the hydraulic valve is displayed by detecting the opening or closing state of the mercury switch. The device has the advantages of low manufacturing cost, and flexibility and reliability, and overcomes the defects of high price and easy failure when a proximity switch and a Hall probe are used to detect in the prior art.
Description
Technical field the utility model relates to the valve position switch state-detection of Chemical Manufacture with hydraulic brake plate valve or hydraulic pressure base-plate valve, directly relates to the valve position switch state-detection of ammonia workshop section with the hydraulic pressure base-plate valve.
Background technique valve valve position detection device is a kind of application device of keeping the safety in production more widely, have at present near two kinds of switch, hall probe approved products, these two kinds of products in use, rate of fault height, and price is more expensive.
The summary of the invention the purpose of this utility model provides a kind of valve valve position detection device reliable and cheap for manufacturing cost.
The utility model is to realize like this, hydraulic valve valve position detection device, have valve (10), oil hydraulic cylinder (9), base (6), support (4), connecting rod (2), mercury switch (3) and limited location fork (11), it is characterized in that: described connecting rod (2) one ends are provided with mercury switch (3), and the other end is provided with limited location fork (11) and links to each other with the valve rod (8) of valve (10).
As a kind of improvement project of the present utility model, hydraulic valve valve position detection device is characterized in that: described connecting rod (2) is connected on the support (4) by valve inspection rotating shaft (5).As the further improvement of the utility model scheme, hydraulic valve valve position detection device is characterized in that: the right lower side that described support (4) is gone up rotating shaft is provided with position-limited nail (1).The utility model has overcome to use can only provide a kind of shortcoming of closing signal near switch, hall probe.
Appended drawings is a mode of execution structural representation of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment the utility model hydraulic valve valve position detection device, moving down drive valve inspection connecting rod 2 by valve rod 8 rotates around fixed rotating shaft 5, mercury switch 3 disconnects, demonstrate valve closing, when valve rod 8 made progress, because the deadweight of mercury switch 3, mercury switch 3 positions moved down, the mercury switch conducting demonstrates valve opening.The base 6 of valve valve position detection device is fixed on the valve 10, and the length of the height of support 4 and connecting rod 2 is according to the apparent size customization of valve.
Claims (3)
1. hydraulic valve valve position detection device, have valve (10), oil hydraulic cylinder (9), base (6), support (4), connecting rod (2), mercury switch (3) and limited location fork (11), it is characterized in that: described connecting rod (2) one ends are provided with mercury switch (3), and the other end is provided with limited location fork (11) and links to each other with the valve rod (8) of valve (10).
