(57) Abstract:

The invention relates to the field of construction, in particular for housing and utilities associated with the development of domestic sewage multi-storey buildings. The objective is to reduce noise and improve reliability of operation in the system of internal drainage by reducing the possibility of clogging. In the internal drainage multi-storey buildings, including vertical risers connected to the exhaust pipe by means of a bent pipe, risers consist of alternating pipe segments, and some segments are made of pipes with spiral ribs and the other of smooth tubes, the length of the pipe segment with spiral ribs is the length equal to at least the height of one floor, and the length of smooth pipe equal to the length of three floors. Cranked tube is massive, thick-walled, mostly from cast iron, and attached one end to the bottom of the vertical riser, made in the form of a segment of pipe with spiral ribs, the other end of the pipe attached to the exhaust pipe. 1 C.p. f-crystals, 2 Il.

The present invention relates to the field of construction, installation of buildings.

The main task in designing plumbing systems is to increase its reliability.

In the famous sewer system, consisting of sewer rising mains connected at the bottom with a discharge pipe, in the area of the riser, located in the basement of the installed expansion chamber, fitted with a lid, separating it from the cavity of the riser. When this chamber is connected to the discharge pipe by means of additional pipeline (SU inventor's certificate N 1719565, E 03 C 1/20, 1992).

Known widely used internal drainage multi-storey building includes vertical struts connected to the exhaust pipe through the elbow. Sewer risers made of cast-iron pipes of diameter 50-100-150 mm, connected to the sockets. Struts strengthen clamps on each floor under the cowl. Over the risers have an exhaust pipe connected to the sewer mains through a coupling, because the diameter of the exhaust pipe is increased by 50 mm compared to the diameter of the riser. The lower part of the riser connected to a discharge pipe through elbow (Handbook of the designer. Inside the disadvantages of the known systems should be attributed to the presence of noise, occurs when the drop of water supply and solid waste from a great height.

The objective of the invention is the creation of a sewage system for maximum ease of use for consumers, reducing noise, improving reliability by reducing the possibility of clogging the sewer system.

The task is solved in that in the internal drainage multi-storey buildings, including vertical risers connected to the exhaust pipe by means of a bent pipe, risers consist of alternating pipe segments, and some segments are made of pipes with spiral ribs and the other of smooth tubes, the length of the pipe segment with spiral ribs is the length equal to at least the height of one floor, and the length of smooth pipe equal to the length of three floors. Cranked tube is massive, thick-walled and attached one end to the bottom of the vertical riser, made in the form of a segment of pipe with spiral ribs, the other end of the pipe attached to the exhaust pipe. Crankshaft socket mainly made of iron.

The use of alternating segments of pipe with Speer is the range of water on the plots change direction, becomes smaller. Applying instead of the usual lower crankshaft massive thick-walled tube, for example, cast iron, elbow pipe reduces the noise generated by flow changes.

Changing the shape of the flow from laminar to a segment with a smooth pipe turbulent on a section of pipe with spiral ribs leads to aggregate the destruction of large pieces of solid waste, which reduces the possibility of clogging the system.

In Fig. 1 schematically shows the internal drainage multi-storey buildings where the vertical sewer riser made of pipe segments with spiral ribs 1 and segments smooth tubes 2. Pipes are fastened by means of clamps 3 to a building wall 4. Crankshaft thick-walled pipe 5, mainly cast iron, located on the ceiling of the basement, connected to the exhaust pipe 6 and with the lower part of the riser, made in the form of the pipe segment 1 with spiral ribs. Cut pipe with spiral ribs 1 is connected to a crankshaft of the pipe 5 through the coupling 9. Similar coupling 91cranked pipe connected to the discharge pipe 6. Using a clamp 7 exhaust pipe attached to the ceiling 8. the spiral ribs (left), the coupling (center) and cast iron elbow (located behind the coupling).

The sewer system is installed as follows.

Massive thick-walled, mostly iron, elbow pipe 5 is attached to the connecting sleeves 9 and 91after which attach through the coupling 9 to the pipe with spiral ribs 1 and through the clutch 91to the discharge pipe 6, which is fastened to the overlap 8 through the yoke 7. Cut pipe with spiral ribs 1 set after a massive elbow to the height of at least one of the floor, i.e., the minimum height of 2.9 metres. After this, at a height of 10 metres or three storeys establish normal smooth pipe 2. Then the above construction is repeated up to the last floor, for example, 5 times, if the last floor is the 21st floor. To the upper part of the pipe connecting the exhaust pipe 8. The entire structure is fixed to the wall by means of clamps 4.

Thus, the installation developed a sewer system noise when driving sewage is reduced by 6-7 dB.

1. Internal drainage multi-storey buildings, including the struts consist of alternating segments of pipes, some pieces are made of pipes with spiral ribs and the other of smooth tubes, the length of the pipe segment with spiral ribs is the length equal to at least the height of one floor, and the length of smooth pipe equal to the length of three floors, cranked tube is massive, thick-walled and attached one end to the bottom of the vertical riser, made in the form of a segment of pipe with spiral ribs, the other end of the pipe attached to the exhaust pipe.

The invention relates to water and can be used to supply water to residential and administrative buildings

FIELD: control of WC flushing valves.

SUBSTANCE: proposed method of control of WC flushing valve in vacuum collector system includes opening and closing of flushing valve by means of control unit at rate ensuring opening and closing time of 0.25 and 0.4 s respectively. Device for control of WC flushing valve includes at least three working valves. Device and flushing valve are actuated by vacuum created in collector system. Said working valves may return to initial position by means of common piston-type rod made in form of cam which is actuated in its turn by piston in cylindrical chamber. First valve actuated by starting unit brings cylindrical chamber in communication with vacuum source in second valve actuated by cam which brings vacuum source in collector system in communication with drive unit of flushing valve and third valve brings flushing ring or similar unit with water source through pipes and passages.

EFFECT: enhanced efficiency.

FIELD: construction.

SUBSTANCE: plumbing appliance comprises a tubular housing having an inlet for connection to an inlet discharge pipe and an outlet for connection to an outlet discharge pipe. The inlet and the outlet each are configured to facilitate the upgrading of the existing discharge pipe system with the appliance. The plumbing appliance additionally comprises a check water valve located in the tubular housing, a check air inlet valve mounted on the portion of the tubular housing. The check water valve is located in the normally closed position and is designed to provide sewage flow from the inlet to the outlet and to limit the flow from the outlet to the inlet. The check air inlet valve is located in the normally closed position and is designed to provide air flow to the tubular housing and to limit the air flow from the tubular housing. The check air inlet valve is located on a boss located on the upper portion of the tubular housing, the air inlet valve comprising a cylindrical rim sized to fit tightly into the boss and a valve disc mounted at the lower rod end. The rod is mounted vertically slidable in a spider device extending radially inwardly from the cylindrical rim.
