The invention relates to water faucets.Currently, the consumption of fresh water for public services is increasing, accounting for per capita hundreds of liters per day, and in many regions becomes insufficient, is the supply ice possible measures to reduce its consumption (vivid example water in Singapore).The water supply is consumed electricity, pumping equipment is depreciated.In order to reduce water consumption for domestic use in homes, shops factories, institutions offers this invention. Known valve currently used in valves, which when unscrewing by means of handwheel (rod, round disk drive) spindle produces water. The water flow can be regulated depending on the magnitude of unscrewing.Water flows evenly to close the valve, the handwheel, the main disadvantage of valve is that the liquid (water) flows from the opening to closing non-stop, although often the need is periodic, such as washing, hand washing and other items.Also known faucet with a device for washing, for example (1). This invention so far, although it has been 54 years old, has not become widespread. The main disadvantage of this invention should be considered the fact that when the pressure in the water supply network 6 ATM and taking into account friction, suction cone push the button must be 8-9 kg and more than that, of course, not everyone and not everyone will like it.Ippousy water, works great strength, the water pressure in the network and another spring.The device (2) has a device for low water flow. This valve is very inconvenient that when using one hand must be lever is always busy for opening and closing, potential flows.To eliminate the above disadvantages, i.e. to save water consumed for domestic purposes (washing, hand washing), as well as the production, institutions, soup kitchens, etc. and, hence, to reduce water consumption, reduce the cost of feed offered valve with periodic water flow.The invention consists in the fact that it will provide a more economical use of water and the ease of use of the valve with two valve bodies mounted in the same enclosure.The drawing shows the valve in the section.Valve with periodic water supply consists of a housing 1 with an inlet 2 and the drain 3 channels. In the cavity of the housing is fitted with a gasket 4 stop valve 5, overlying the opening 6 in the housing. A stop valve 5 is connected to the spindle 7, which is sealed Salnikov node 8. On the spindle 7 is fixed to the flywheel 9. In korpusa blocked additional shut-off body 12, connected to the actuator in the form of a spring-loaded lever 13 mechanism. The lever mechanism includes a lever 14 connected to the rod 15, the housing and locking body 12 by hinges 16. On the rod guides made in the form of ribs 17, which interacts with the inner surface of the walls of the discharge channel. The outer surface of the guide ribs 17 are made spherical. In the side wall of the body made the hole closed on the outside by a cover 18. Through the hole of mounting the lever system in the body.The valve operates as follows.In the closed position of the shutoff valve body 5 closes the opening 6 in the housing under the action of the spindle 7, and a stop valve 12 closes the opening 11. When this shut-off body 12 is pressed to the wall 10 by the water pressure, and the spring 13. For operation of the valve in a discrete mode of water supply, the consumer presses a hand on the rod 15 upwards, overcoming the force of spring 13. Moving the lever 14 is pushed shut-off body 12 of the baffle 10, the opening hole 11 and the flowing water to the drain channel 3. When the rod 15, the spherical guides which are in contact with the walls of the discharge channel 3, deviate from the vertical axis is akrival hole 11. The lever system 14 reduces the force which must be applied to the rod 15 to overcome the water pressure at the shut-off body 12. Shut-off body 12 is made with a smaller diameter than the stop body 5, as the water flow in discrete mode should be less than in continuous mode.For valve operation mode continuous supply of water, by means of the handwheel 9 turn the spindle 7 and assign the stop body 5 from the hole 6. 1. VALVE WITH PERIODIC WATER FLOW, comprising a housing with inlet and discharge channels, placed in the cavity of the housing and is fitted with a gasket shut-off body, connected with the spindle, and an additional actuator mounted with the possibility of discrete axial movement, characterized in that the lateral wall of the body has a hole, closed on the outside by the cover and in the body cavity of the completed wall with a through hole connecting the inlet and discharge channels, and the specified hole placed additional shut-off body connected with extra drive.2. The valve under item 1, characterized in that the auxiliary drive is made in the form of a spring-loaded lever mechanism containing the rod and the levers, the connection is made guides in the form of ribs, interacting with the inner surface of the discharge channel.3. The valve under item 2, characterized in that the outer surface is made spherical.

FIELD: heating systems; liquid heating systems.
SUBSTANCE: under-ceiling non-evaporating widening tank of heating system has solid casing in form of a canister with level-metering pipe, widening space communicating with heating system and air space separated hermetically from widening space by soft membrane. Air space communicates with environmental air. Membrane is made inform of air bag. Neck of bag is withdrawn out of neck of casing and is connected hermetically with the neck. Plug provided with air hole is tightly inserted into neck of casing. Plug is fastened by screwed cap provided with air hole which is not aligned with hole in plug. Method of detecting of slow leaking of water from heating system is based upon the fact that temperature graph of the system is built in summer without heating. For the purpose values of water level in level-metering pipe of the tank at steady temperature are put along abscissa and values room temperature are put along ordinate; received calibrated curve is subject to calibration. The graph is taken as averaged temperature calibration graph and steady values of outside temperature are drawn above corresponding values of level. When taking subsequent measurements, the averaged temperature is determined again and if the value of level get lower it is assumed that water loss takes place because of leakage or evaporation of water caused by disturbance in leak-proofness of the air bag.
EFFECT: simplified design of tank; better degree of protection of membrane.
