Description

Temper switch for external threaded valves {TAMPER SWITCH FOR OS VALVE TYPE}

The present invention relates to a temper switch for an external threaded valve. More specifically, the temper switch can be easily mounted on an external threaded valve installed in a confined space, and the external threaded valve can be easily mounted even when the temper switch is mounted. The present invention relates to a temper switch for an external threaded valve that can be mounted to a water supply part of a fire fighting facility.

The water supply part of the fire-fighting equipment such as a sprinkler is configured to check the lock of the valve by detecting an alarm or a lamp on the alarm or lamp by sensing the operation of the water shutoff valve in a remote control panel or receiver. In other words, if the valve is left in a locked state when repairing or replacing the pipe of the fire-fighting equipment, the sprinkler will not operate, which may cause human and property damage. By detecting the opening and closing of the water supply valve.

5 is an exploded perspective view for attaching a temper switch to a conventional outer threaded yoke valve, and FIG. 6 is a cross-sectional view of an essential part for explaining the operation of a temper switch mounted to a conventional outer threaded yoke valve.

5 and 6 are conventional methods for mounting the temper switch to the OSY valve, the OSY valve is connected to the body 140, the disk is built, and the disk inside the body 140 is moved up and down valve And a stem 120, a handle 110 connected to the valve stem 120 to be rotated, and a yoke 130 mounted between the handle 110 and the body 140. A switch includes a limit switch 200 for detecting whether the OSY valve is opened or closed, a bracket 235 for mounting the limit switch 200 to the valve stem 120, the bracket 235 and a bolt-nut. A rear plate 230 coupled to 225 and a coupling 220 mounted on the lower side of the limit switch 200 mounted on the valve stem 120 are configured. Here, the operation of the limit switch 200 is detected by the operation of the switching spring 210 is connected to the limit switch 200 the vertical movement of the valve stem 120.

The operation of the temper switch configured as described above, as shown in FIG. 6, the switching spring 210 connected to the limit switch 200 has a coupling 220 mounted on the bulb stem 120 and a lower portion of the handle 110. The yoke 130 mounted on the bulb stem 120 is fixed at regular intervals. Accordingly, when the bulb is opened while the bulb stem 120 is moved upward by the manipulation of the handle 110, the valve is in an open state, and the bulb stem 120 is moved downward by operating the handle 110. In this case, the coupling 220 is spaced apart from the switching spring 210, and the operation of the switching spring 210 transmits the closed state of the valve to the monitoring control panel or the receiver installed at a remote location through the limit number position 200. Done.

However, since the external thread type valves such as the external thread type yoke valves are very narrowly installed, there is a problem in that the temper switch is very difficult to install. In order to prevent malfunction of the temper switch, when installed in the water supply unit, there is a problem that requires much attention.

On the other hand, there is a problem in that the structure of installing the temper switch on the valve stem of the external thread type is complicated to install, and the manufacturing cost is high.

The present invention is to solve the above problems, the purpose of the present invention is to simplify the structure of the temper switch, the production cost is low, and the outside that can be easily mounted the temper switch regardless of the place where the external threaded valve is installed To provide a tamper switch for a threaded valve.

The external threaded valve temper switch according to the present invention is a tempered switch for an external threaded valve mounted on a water supply part of a fire-fighting equipment such as a sprinkler and detecting an opening / closing state of the water supply valve. In the hollow rectangular pillar shape, the switch body 20 is accommodated inside the limit switch 30 for outputting a predetermined detection signal, and the valve stem 120 of the outer threaded valve extending to the switch body 20 It is characterized in that it comprises a bracket 21 which is in close contact with the contact and the mounting holder 10 of the semi-circular arc shape is coupled to the valve stem 120 by the bracket 21 and the coupling means.

In addition, in the external threaded valve temper switch according to the present invention, the nut mounting holes 22 and the bolt mounting holes 11 which penetrate outwards to the surfaces corresponding to the bracket 21 and the mounting holder 10 are respectively provided. Each is further formed, the coupling means, characterized in that the bolt 13 and the nut 14 and the spring 12 are coupled through the nut mounting port 22 and the bolt mounting opening (11).
