Abstract
The utility model relates to a signal butterfly valve for fire fighting, which is characterized in that a worm gear is equipped with a limit device, a travel switch is arranged in a casing, and the travel switch is equipped with a limit rod. As the worm gear is equipped with a limit device, when the worm gear rotates to a certain position for using, the limit device contacts with the limit rod to further touch the travel switch, because a connector is connected with an alarm of a console, the console can send signals after the travel switch is touched, thereby bringing convenience for system personnel to operate, further, as a contact point is formed by the worm gear and the travel switch during rotating, opening and closing signals can be provided effectively via rotation of the worm gear, and signals for connecting acousto-optic facilities to provide sound and light can be output, thereby the utility is generally used for matching fire fighting devices.
Description
Technical field:
The utility model relates to the automatic control technology field of valve, the specifically a kind of fire-fighting Signal butterfly bamper that can control opening travel, especially design mechanical connection relation wherein.
Background technique:
Existing reed valve is at axle head turbine and worm decelerator to be set at present, detects control by personnel, operates.But, on the fire line, must have warning device to show at operating console.So the display mode of existing butterfly valve can't realize the interlock of signal, in time sends alarm signal.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved fire-fighting Signal butterfly bamper, and it can overcome the some shortcomings that butterfly valve in the prior art can't send alarm signal.
To achieve these goals, the technical solution of the utility model is: a kind of fire-fighting Signal butterfly bamper, it mainly comprises housing and is located at housing interior worm gear and worm screw, it is characterized in that: worm gear is provided with a limit stoper, be provided with position limit switch in the housing, position limit switch is provided with the position-limited lever that matches with limit stoper.
Worm gear of the present utility model is provided with a limit stoper during use, when worm gear forwards certain position to, limit stoper just touches position-limited lever, then touch position limit switch, because connecting head links to each other with the alarm buzzer of operating console, after position limit switch is touched, operating console will send " signal ", so that operation system personnel operate, because worm gear forms a point of contact with position limit switch in rotation, just the signal of opening and closing can be effectively provided, and connection acousto-optic facility can be exported by the rotation of worm gear, the signal of sound with light is provided, generally is used to fire fighting device supporting.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises housing 7 and the worm gear 2 and the worm screw 1 that are located in the housing, and its difference with the prior art is: worm gear is provided with a limit stoper 3, is provided with position limit switch 5 in the housing, and position limit switch is provided with the position-limited lever 4 that matches with limit stoper.The bottom of housing is provided with a connecting head 6, and connecting head links to each other with position limit switch.Limit stoper is arranged on the circumferential surface of worm gear, is convex.
In force, worm gear matches with worm screw and forms a retarder, and wherein worm gear is provided with a limit stoper after processing.(stroke that the last figure color part of the worm gear of number in the figure 2 is a butterfly valve) is when worm gear forwards certain position to, limit stoper just touches position-limited lever, then touch position limit switch, because connecting head links to each other with the alarm buzzer of operating console, after position limit switch was touched, operating console will send " signal ", so that operation system personnel operate, after worm gear was rotated further, and limit stoper breaks away from position-limited lever, signal will restore.Because worm gear forms a point of contact with position limit switch in rotation, just can effectively provide the signal of opening and closing by the rotation of worm gear, and can export connection acousto-optic facility, the signal with light is provided, generally be used to fire fighting device supporting.
