Description

In central water heating systems, there are vents with a float, such as glass, that act upon changes in the level of WATER. In the plunger case, through a lever transmission, a balanced spool that controls the release of air into the atmosphere. In the proposed plunger for OPPORTUNITIES of forced re-adjustment In the direction of the longitudinal axis of the cylindrical spool with the working surface located at the end, the spool box is provided with an oblique slot for the roller mounted on the lever lever attached to the spool. On the inner side A fibrous pad with an air inlet is pressed into the end part of the spool box and the working (end) part of the spool is pressed against it. In order to shut off the plunger by closing the air outlet from the outside, if foreign bodies get between the working side of the spool and the fiber gasket of the box

-adjustment made in the form of a crank arm fixed on the lid of a plunger, one shoulder of which is supplied with an elastic stopper and adjustable weight as a vessel. Under the action of water poured from the plunger, the vessel automatically moves along the shoulder and turns the lever to close the air outlet with an elastic plug. Equip the other lever arm with a counterweight.

In FIG. 1 shows a vertical axial section of a plunger; FIG. 2- VIEW of the plunger from above; FIG. 3-section of the slide valve box in AB in FIG. one; FIG. 4, 5, b - the type of the spool in three projections; FIG. 7, 8-VIEW In two projections of the plunger with a safety device.

The housing 7 of the plunger is connected to the network of the central heating system with its mouth / 2. In the casing / box there is also a glass float 2 in a grid of copper wire, connected by a lever transmission 4, 4 with an air discharge valve. The cover 9, attached to the flanges of the hull by bolts 77, is provided with a hole for the passage of the lever 4, having rifled walls to strengthen the flat casing 5, in which the lever 4 of the transmission is located. The flange of the casing 5 is attached to its flange / 5 cylindrical spool box 6, provided on the side of the casing with an oblique cut 75 and at one end side with an air outlet 3. From the inside the end wall has a pressed fiber gasket 27 (Fig. 3). A cylindrical hollow valve 7 is inserted into the cavity of the box 6 with a working end surface adjacent to the extreme position of the spool when the float 2 is raised to the fiber mat 21 of the box 6. In the middle part of the side surface of the spool 7 there is a slotted hole 19 for securing the threaded end of the lever 4 The same lever is attached to the rim 22, which, when the lever is moved, rolls along the walls of the slot 13 of the slide valve 6. In one plane with the hole 19, perpendicular to the longitudinal axis of the slide 7, through air channels 18, 18, communicating through the slot 13 a cavity of a plunger with a cavity of a valve, which in turn is connected to a number of channels 20.20, in the end part of the valve, with a cavity of a valve box equipped with an air outlet.

To prevent water flowing out of the plunger when clogged, the spool box on the lid 9 is secured with a safety device in the form of a crank lever 14, 14, on one shoulder of which a adjustable counterweight 17 is located, and on the other, a stopper 15, closing the air outlet of the spool box . On the lever (shoulder) 14, a fixed load 16 is placed in the form of a vessel (bucket), automatically moving on the roller along the lever 14 under the action of water poured into the vessel from the plunger, and turning the lever 14, 14 to lock the air outlet hole.

When the casing is filled (air cfm), the float 2 is lowered and through the lever gear moves the spool b away from the surface of the fiber mat 2 /, as a result of which the plunger body is connected with the outside air. When the water rises, the float also rises, moves the gold to the end wall of the box 6 and presses it against the fiber mat, separating the plunger from atmospheric air.

The subject invention.

1. A plunger for central heating systems using a float controlling by means of a lever transmission the movement of a spool balanced by air pressure, characterized in that for forcing the spool 7 to be swapped, the wall of the spool box 6 is provided with an oblique slot 13 for a roller mounted on a lever lever attached to the valve. 4, 42. In the case of a plunger as described in claim 1 lever 4, fitted on one shoulder with an elastic stopper / 5 and adjustable load / 5 in the form of a vessel, automatically moving on the roller along lever J4 under the weight of water poured out from the plunger, and on the other shoulder-counterweight / 7.
