Description

The utility model relates to fire fighting equipment, namely, to be used to open (close) underground hydrants and attach fire hoses in order to select water from water supply networks for fire needs.

The fire column KPA (GOST R 53250-2009) is known from the prior art, containing the following main parts: upper and lower bodies, a central key (socket), a bolt, a sealing ring, a valve, a head, a sealing ring, a guide sleeve, a gasket and a threaded ring .

The disadvantage of this design is the fact that with certain changes in the axial position of the end of the rod mating with the fire hydrant column (the stem is underestimated, the stem is overestimated), it becomes impossible to use the KPA fire column with a central key fixed in the axial direction.

The technical result of the claimed utility model is to compensate for the axial displacement of the square end of the fire hydrant rod, with which in the working position the square coupling of the central key of the fire column is mated.

The specified technical result is achieved due to the fact that in the fire column containing the lower and upper bodies, a central (end) key, a bolt, an o-ring, a valve, heads, a guide sleeve, a gasket, a threaded ring, according to a utility model, on the upper column body split washers are fixedly mounted, flanges are made on the central (end) key rod, while the central key rod in the upper case is made with sealing elements located in the grooves of the rod.

The stroke of the central (end) key is limited by the structural elements of the stem, the so-called collars, split washers are fixed on the upper body of the column, covering the rod between the collars.

The essence of the device is illustrated by drawings, where in FIG. 1 shows a general view of a fire tower, and FIG. 2 - movable central (end) key.

In FIG. 1, the fire column contains a lower case 1, an upper case 2, a central (end) key 3, a bolt 4, an o-ring 5, a valve 6, a head 7, an o-ring 8, a guide sleeve 9, a gasket 10 and a threaded ring 11.

At the same time, split washers 12 are fixedly mounted on the upper case 2, (Fig. 1, 2) of the column, and flanges 13 are made on the rod of the central (end) key. The rod of the central (end) key 3 in the upper case 2 is made with sealing elements 14, placed in the grooves of the stem.

The device operates as follows.

The KPA fire tower is installed using a threaded connection by screwing it onto the hydrant by turning its body clockwise (the socket wrench remains stationary). Next, the hydrant valve (with closed valves of the column) opens by turning the central (end) key counterclockwise, and, if necessary, it is possible in this improved design of the KPA fire column to move the central (end) key along its axis (the hydrant valve fully opens at 10 -14 revolutions of the central (end) key), and water from the water supply network enters the cavity of the KPA fire column. After connecting the fire hoses to the heads of the fire column, the valves open and water enters the hose line.

Claims (1)

A fire column containing lower and upper bodies, a central (end) key, a bolt, o-rings, a valve, heads, a guide sleeve, a gasket, a threaded ring, characterized in that split washers are fixedly mounted on the upper column body, and the central key flanges, while the Central key rod in the upper case is made with sealing elements located in the grooves of the rod.
