RU173995U1 - SIGNAL MODULE OF THE SPRINKLER CONTROL UNIT - Google Patents

Abstract

The signal module is designed to detect the operation of the sprinkler sprinkler and to generate signals and commands for automatic fire extinguishing systems, consists of a plastic case with metal embedded in the connection points with pressure control lines and with a signal line, and has a box-shaped pressure switch mounted on the top module housing wall by means of metal embedded elements mounted in the housing.

Description

The utility model relates to automatic fire extinguishing installations and is designed to detect the operation of a sprinkler sprinkler and to generate signals and commands for automatic fire extinguishing installations based on control units with signal sprinkler valves.

The prior art control unit sprinkler water-filled, RU 128115, used in fire extinguishing installations.

The known assembly includes a signal module, which is a metal parallelepiped with internal channels and with at least one built-in pressure signaling device, through holes are used to fasten the signal module to the signal valve body.

The above signal module is selected for the prototype.

A disadvantage of the known module is its high complexity of manufacturing associated with the manufacture of channels in a metal case and cutting threaded outputs (connections).

The objective of the proposed utility model is to increase the manufacturability of production and the cost of the design.

The problem is solved by creating a signal module, consisting of a housing, which is made in the form of a parallelepiped with internal channels, with through technological holes designed to attach the module to the valve body of the alarm, with a built-in pressure signaling device, according to a utility model, a housing made of impact-resistant plastic is used , with metal embedded elements installed on the sides of the housing, which are made in the form of threaded bushings with the possibility of connecting I have to them a signal line and two oppositely located pressure control lines, while on the upper side of the case there are two mounting sockets for a pressure signaling device, with four metal embedded elements mounted around each socket made in the form of threaded sleeves by means of which a signaling device is fixed on the module case pressure, made in the form of a box-shaped housing, consisting of a base, a cover, an internal control and alarm unit, while on the rear wall of the module housing I made the outputs of the internal channels in the form of landing sockets with the possibility of their connection with the channels of the signal line and pressure control lines of the signal valve.

The utility model is illustrated by drawings (Fig. 1-6).

FIG. 1 is an isometric front view of a signal module with signal and control lines connected to it;

FIG. 2 is an isometric rear view of a signal module with signal and control lines connected to it;

FIG. 3 is a top view of a module case;

FIG. 4 is a rear view of the module housing;

FIG. 5 is a section AA in FIG. 4 module cases;

FIG. 6 is a section BB in FIG. 4 module housings.

The signal module is based on a housing 1 with internal channels 2, 3, 4 and through technological holes 5, 6, 7; a pressure alarm is installed on the housing, consisting of a base 8, a cover 9, a control and alarm unit 10, on the sides 11 and 12, metal embedded elements made in the form of threaded sleeves 13, 14, 15 are mounted at the exits from the internal channels, while on the upper side of the module case there are two mounting sockets 16 with holes around the sockets with embedded elements made in ide of bushings 17, 18, on the rear wall of the housing there are mounting sockets 19, 20, 21 of internal channels for interfacing with the internal channels of the signal valve.

By means of bolts through the holes 5, 6, 7, the signal module is attached to the signal valve body, the pressure indicator is connected with its body 8 to the module case 1, while for orientation and tight coupling, the mounting sockets 16 are used, and for fixing the screws that are screwed into the bushings 17 are used and 18, external connections of the signal and control lines are carried out through the bushings 13, 14, 15.

Impact resistant plastic (new material) is used to manufacture the cases of the signal module and the signaling device for the pressure indicator cover, while the cases and the cover are made by automatic molding in a mold with pre-laying of purchased threaded bushings (new structural parts).

This technology greatly facilitates the manufacturing process, reduces the cost of products, while ensuring high quality and labor productivity.

Thus, the task is successfully solved.

Claims (1)

The signal module of the sprinkler control unit, consisting of a casing, which is made in the form of a parallelepiped with internal channels, with through-hole technology for fastening the module to the casing of the signal valve, with an integrated pressure switch, characterized in that it uses a casing made of impact-resistant plastic, with metal embedded elements mounted on the sides of the case, which are made in the form of threaded bushings, with the possibility of connecting a signal to them a line and two oppositely located pressure control lines, while on the upper side of the housing there are two mounting sockets for a pressure signaling device, with four metal embedded elements mounted around each socket made in the form of threaded sleeves, by means of which a pressure signaling device mounted on the module case is made in the form of a box-shaped housing, consisting of a base, a cover, an internal control and signaling unit, while on the rear wall of the module housing there are made odes of internal channels in the form of landing sockets with the possibility of their connection with the channels of the signal line and pressure valve control lines of the signal valve.
