RU81975U1 - INSTALLATION OF MIXED WATER SUPPLY - Google Patents

Abstract

A mixed water supply installation, including a boiler room, cold and hot water pipelines, a water mixing and supply system, and a shower cubicle block, characterized in that the electronically controlled water mixing system is made of polypropylene pipes in the form of three circuits interconnected at the outlet of of which a temperature sensor is located, electronically connected to the controller, which is controlled by electro-valves installed on the bypasses, while the mixed water supply system to the shower cubicle block is single-tube.

Description

The utility model relates to pipe fittings, namely, devices for mixing water and can be used in water supply systems for showers of industrial and municipal enterprises, as well as in swimming pools and bath and laundry trusts.

Conventional water mixing devices are known in the form of mixers with inlets for cold and hot water and an outlet for mixed water entering the shower head or spout. (Russian Patent No. 2172882, CL F16k 11/16, 12/15/1999.)

However, such devices are based on a special design, which requires additional material costs.

Other traditional water mixing plants containing cold and hot water nozzles with manually controlled valves have an increased irrational flow rate due to the long time it takes to turn on, turn off and set the water temperature when the water is not in good use. (Russian patent for utility model No. 69099, class E03C 1/04, 12/10/2007)

In addition, the separate supply of cold and hot water with the subsequent mixing of these flows manually leads to increased humidity in the rooms, the formation of steam and condensate.

The objective of the utility model is to obtain water of a given temperature, without additional material costs, using available pipe fittings, as well as to improve operating conditions and reduce water losses.

The technical result is achieved by the fact that in the installation of mixed water supply, including a boiler room, pipelines of cold and hot water, a system for mixing and supplying water and a block of showers,

The electronically controlled water mixing system is made of polypropylene pipes in the form of three circuits interconnected, at the outlet of which there is a temperature sensor electronically connected to the controller, which is controlled by solenoid valves installed on bypasses, while the mixed water supply system to the shower cubicle block is single-tube.

The figure shows a General diagram of the installation of mixed water supply.

The mixed water supply installation includes a boiler 1, pipelines 2, 3 of cold and hot water, a system 4, 5 for mixing and supplying water to the block of shower stalls 6.

The electronically controlled water mixing system 4 is designed to mix hot and cold water to a predetermined temperature with an accuracy of 0.1 ° C. System 4 consists of three circuits interconnected, made of polypropylene pipes with a diameter of 50 mm, which allows water to pass through and mix at a flow rate of 10 to 200 liters per minute. It effectively mixes the water, controlling the temperature with a temperature sensor 7 located at the outlet of the last circuit. The signal from the temperature sensor 7 is supplied to the controller 8, through which the temperature in the system 4 is set.

The controller 8 is controlled by two valves 9 to feed the main stream through the bypass 10.

The system 5 for supplying mixed water through a watering can on the skin of the consumer is made single-tube. It is equipped with a pressure reducing device 11, which significantly affects the flow of water.

Installation, working at low pressure, can achieve water savings of up to 60%.

The installation has a drive for switching on, which can be either mechanical by means of traction through the pedal, electrostatic or electromagnetic, the electromagnetic valve turns on water when

person at a distance of 700 mm from the shower. Turning on after 2 seconds. The command is given by a volumetric sensor.

Installation works as follows.

Cold and hot water flows through pipelines 2, 3 to the mixing system 4, where it is mixed to a predetermined temperature. The temperature is controlled by temperature sensor 7. Controller 8 sets the set temperature by the signal of temperature sensor 7. Mixed water is supplied to the shower head.

The proposed utility model is easy to design and maintain. The first experiments on the application gave the desired result in industrial enterprises, swimming pools, bath and laundry trusts.
