Abstract

THE WATER SUPPLY SYSTEM OF THE SHOWER RAILWAY WAGON, containing the hot and cold water tanks, which connect the supply pipes from the common tank with the taps and the flow pipes communicated with the taps with a mixer, which is different with the purpose of turning in the conditions of service braking and acceleration of the car by eliminating the adjustment of the faucet consumables during the shower procedure, the tanks of hot and cold water are made of equal internal dimensions and are located in the same transverse vertical plane of the car one. level.

05 The invention relates to railroad transport and concerns railroad water supply systems. A water supply system for a stuffed railway car is known, which contains an oak; hot and cold water, with which there are no water pipes from the common tank of the pipe; taps and flow tubes communicated by taps with a mixer 1. Il due to unequal sizes and arbitrary arrangement of tanks, as well as open taps of supply pipes, due to frequent service braking and acceleration of the car, which create significant accelerations, the height of the water column above the c- the mixer, and the dimensions of the height of hot and cold water are changed by different values, as a result of which the difference in pressure in the supply pipes changes, and this necessitates constant adjustment of the valves of the supply pipes. The aim of the invention is to increase the reliability of the system under conditions of service harmony and acceleration by excluding; adjusting taps and flow tubes in the shower head procedure. The goal is achieved by the fact that in a water system: a shower rail train containing hot and cold tanks, 1 "1yds, with which supply pipes (3) 6Hiei4) byk with pipes and a consumption of pipes, supplied by valves from a mixture: v :; .--, tanks of hot and cold water. equal internal dimensions and location ... kenk: one transverse vertical: OCKOc and the carriage on the same level. Mcj fi | 1 schematically shows the mouth of H. :: ii.:, General view; FIG. 2 - the same, from above; in fig. 3 is a diagram of the system for the flow of the shower railroad train on a) i; a in 11O1: the transverse plane. W. installed on the wagon 1, the wisp / chonp wagon 2 system consists of a common supply pipe of hot water tank 4, supply pipes about. races () bottom pipes 6, cranes 7, installed. i-M supply pipes of tanks, a mixer 8 with a duel mesh, located in L .; displacement 9, cold water tank of taps 11 installed on the rac. | tubes of tanks and servants; them to provide the possibility of repairing the mixer without draining water from the tanks. Replenishment of the tanks of the shower water supply system is carried out from the common tank 12 of the car-supply system. FIG. 1 The following symbols are used; Hfi is the height of the water column above the mixer at the absence of acceleration (standing or with a uniform movement of the car); - the height of the zod column above the mixer in the tanks of the duP1Ev water supply system when braking or accelerating the car; HTO is the height of the water column above the mixer in the tank of the general water supply system when braking or accelerating the car. The system works as follows. When opening the cranes 7 of the zod, the common tank 12 of the water supply system of the car enters the hot 4 and cold 10 vol. Tanks. After the tanks are filled with water, the specks 7 are set to the Closed position, which prevents the penetration of cold water into the hot water tank and the impact of the cold water column on the mixer during torpedoing and acceleration of the car, which results in a change in water temperature in the mixer. With the help of built-in or external heating devices, the water in the hot water tank 4 is heated. Hot water flows into the mixer 8 and from there, after opening the valves, connect the customer through the drain grid to the consumer. The temperature of the WATER in the grid is ensured by the fact that in tanks located in the same transverse plane, a: the surface of the water is taken to have the same angle of pack: 1 and the difference in perpendicular from the water surfaces to a plane parallel to the surface; the zodia and the passing through the mixer remain equal both at rest (L-1p) and and in the movement of the car, which means that the difference in pressure, and hence the temperature of the displacement of water, remains unchanged. The imenimenenie water supply system of a bottom rail wagon compared with similar systems will increase the reliability of work in the conditions of movement of the car; improve the carriage ergonomic indices nute.m eliminate the constant adjustment of the mixer taps; eliminate complex and unreliable automatic water temperature controllers; improve the operating conditions of the car. // f
