Abstract

SUMMARY OF THE INVENTION: An overflow pipe 6 in the form of a loop with a bend in the upper part is connected at one end with a discharge pipe 4, the other with a siphon 5. The outlet 2 with a locking element 3 is connected to the pipe 4 and installed in the siphon 5 concentrically with the formation of an annular gap, communicating cavity sanitary device 1 with a pipe 6, made tight, with an air tube 7, the upper end of the tube 7 is open and placed above the max, the water level in the device 1, the lower is connected to one of the branches of the loop at the operating water level in the device 1. 1 silt .

Description

The invention relates to spillway fittings for sanitary appliances and can be used to drain wastewater from bathtubs, shower trays, sinks, wash basins into the sewer network.

Closest to the invention in terms of technical nature and the achieved result is a spillway fixture of sanitary equipment, containing a discharge with a zZAorn element, a downpipe, a siphon and an overflow pipe in the form of a loop with an overflow in the upper part, connected at one end to the outlet pipe, and the other with a siphon, while the locking element is installed on the pipe between the nodes connecting to the siphon of a curved overflow pipe. Known spillway valves provide emptying and overflow through the same hole in the sanitary device, it works in a non-pressure mode and therefore is not reliable enough.

The aim of the invention is to increase reliability by ensuring the operation of the overflow pipe in pressure mode.

This goal is achieved by the fact that in a spillway fitting containing an outlet with a locking element, a downpipe, a siphon and an overflow pipe in the form of a loop with an inflection in the upper part, connected at one end to a downpipe and the other to a siphon, the outlet is connected to a downpipe and is installed concentrically in the siphon with the formation of an annular gap communicating the cavity of the sanitary device with an overflow pipe sealed with an air pipe, the upper end of which is open and placed above the maximum level s in the instrument, and the bottom is connected to one of the branches of the loop at the operational level of water in the device •.

This set of distinctive features ensures the operation of the overflow valve in the pressure mode, when the increased flow rates with smaller outlet diameters allow maintaining the water flow rate that is normal, and prevent clogging during overflow operation, and when the device is emptied, water flows from the overflow pipe in the opposite direction and pushes precipitation in a siphon.

The drawing shows the spillway fittings sanitary appliances, section.

The drainage fixture of the sanitary appliance 1 comprises an outlet 2 with a locking element 3, an outlet pipe 4, a siphon 5 and an overflow pipe 6 with an air tube 7, an annular gap 8, a connecting nut 9.

Outlet 2 is installed in a siphon 5 concentric with the formation of an annular gap 8, which communicates the cavity of the sanitary device with an overflow pipe 6, which is made in the form of a loop with an inflection and tight with an air pipe 7, the upper end of which is open and placed above the maximum water level in the device, and the lower one is connected to one of the branches of the loop at the operational water level.

The fittings work as follows.

With the outlet and water filling of the sanitary appliance, the overflow pipe will also be filled and, having reached the maximum level due to self-siphoning, will be discharged through the outlet pipe into the sewer network in pressure mode. When water is drained through the overflow pipe, the water level in the device will decrease and, having reached the junction of the air pipe with the overflow pipe, the decrease will stop, since air through the air pipe, sucking into the overflow pipe, will stop the suction of water from the device. Complete discharge of water from the sanitary device is provided by opening the shut-off element.

Claims (1)

Claim Spillway fittings for sanitary appliances, comprising an outlet with a locking element, a downpipe, a siphon and an overflow pipe in the form of a loop with an inflection in the upper part, connected at one end to a downpipe and the other to a siphon, characterized in that, in order to increase reliability due to the operation of the overflow pipe in pressure mode, the outlet is connected to the outlet pipe and installed in a siphon concentrically with the formation of an annular gap communicating the cavity of the sanitary device with an overflow pipe made minutes with an air tube, the upper end of which is open and is situated above the maximum water level in the appliance, and the bottom is connected to one of the branches of the loop at the operational water level in the appliance.
