The invention relates to valves and is intended for cleaning of industrial premises, equipment/tanks, vats etc./, for example, in Breweries. It can be used for these purposes in other industries.Known valve for fluid supply /cm the first lever and raznoliki lever, installed inside the hollow arm on parallel axes, with one shoulder start lever is kinematically connected with the stem of the locking member, and the short arm raznolikogo lever interoperable with the free shoulder pad lever, in addition, at the end of the long arm raznolikogo lever is made hollow to click on it when opened.Performance tests conducted on the brewery A. O. Bayern after fabrication of prototypes, revealed a number of inconveniences crane operations.These inconveniences are, first, that during long-term exposure of the valve in the open position by pressing on the notch raznolikogo arm, the finger gets tired, and therefore does not always ensure the desired operating mode of the crane.Secondly, the crane is not equipped with means to maintain it for a long time in a fixed open position without constantly pressing the lever and, if necessary, to quickly close it.To address the first shortcoming is more convenient would be to work with crane not by pressing a finger on the notch raznolikogo arm, and a gripping handle all hand and pressing it with the back part of the palm.The problem to which the invention is directed, is to further enhance the experience at the opening of the valve due to the possibility of pressing the lever back part of the palm of the hand and an even greater reduction efforts.Another objective is to enable automatic fixing of the locking body of the crane at the maximum open position and, if necessary, quick closing after holding it in this position.The task is achieved by the fact that the crane is equipped with an additional raznolikim lever mounted on the same axis as the starting lever and covering long part of the shoulder, the arm, the long arm of the mentioned raznolikogo arm performed a longitudinal through slot in the plane of its rotation, and its short arm is made of two halves, separated through longitudinal slot and located at an angle to its long side, and provided with a roller mounted on its end on the axis, with the possibility of contact with the notch of the long arm of the first raznolikogo arm, and the two halves of the short arm connected to the roller axis.On the valve casing secured siteplease element, and at the end of the Yong trigger interoperable with SitePlayer element.In Fig.1 shows a longitudinal section of the valve of Fig.2 section a-a in Fig.1.The valve consists of a casing 1, the input nozzle 2, which tightly can sit down flexible hose /not shown/, the locking member 3, a spring-loaded by a spring 4, seat 5, which is at the same time and the output connection, the start lever 6, raznolikogo arm 7, arm 8 and the additional lever 9, also made raznolikim, with the roller 10.To ensure manufacturability and Assembly of the valve body is made to reduce the weight of impact-resistant plastic or aluminum alloy, consists of three parts 1, 11, 12, fastened tightly to each other.Part 11 of the casing, to which is attached tightly fitting 2 has a cavity and a number of holes located around the circumference and the same location with the same holes provided in the middle part 12 of the casing and intended for the passage of fluid.In part 12 of the housing for placement of a start lever 6 and the stem 13 of the valve body 3 includes a groove 14 /Fig.2/, and to ensure reliable sealing of the above-mentioned rod sleeve 15 made of stainless steel. While on the rod 13 is provided with annular groove with the form, close the form condensed liquid stream that provides a greater flow rate of fluid at the exit.The ends of the start lever 6, is installed inside the handle 8 on the axis 17, is made in the form of forks, one of which connects with the rod 13 and the other end comprises a fork with long shoulder raznolikogo lever 7 near the axis of rotation 18.An additional lever 9 is installed on the same axis 17 with the starting lever 6 and covers the handle 8, where coverage in the plane of its rotation has a longitudinal through slot that is open on one side. The short arm of this lever is located at an angle to its long shoulder and is made with a through longitudinal slot that is open on two sides.The roller 10 is placed on the end of the short arm of the lever 9 on the axis 19 that is parallel to the axes 17, 18 and connecting the two halves of the slot of the short arm. The roller 10 is in contact with the notch of the long arm of raznolikogo lever 7.Near the end of the shoulder pad of the lever 6 from the side of the rod 13 is rigidly attached to the flat spring 20, which consists of two wires 21 /Fig.2./, made of spring steel. These delays can be moved along their axes with the subsequent rigidity of pixalation when fully open the locking body 3 with the trigger 22 is rigidly attached siteplease element 23.Valve for fluid supply works in the following way. When clicking on an additional lever 9 by gripping the back part of the palm of the hand lever is rotated around the axis 17 and the roller 10 in contact with the notch raznolikogo lever 7, rotates the lever about the axis 18, which in turn turns are in contact with him starting lever 6.When turning the end of the start lever is moved together with the rod 13 and a locking body 3. In this case, when an incomplete pressing the lever 9, i.e., not to failure, the feeding speed of the liquid can be regulated. Pressing the rear part of the palm of the hand on the lever 9 to the failure by the girth of the lever with the arm of the crane arm the trigger 22 under the action of the spring 20 drops on siteplease element 23 and the valve is set in the full open position.For closing the valve, the trigger 22 is released from engagement by pressing it down and simultaneously released from the pressing lever 9. 1. Crane for conveying fluids, comprising a housing, a spring-loaded shut-off body with the rod, a lever and raznoliki lever mounted inside the hollow arm on parallel axes, with one shoulder start lever is kinematically swasey with a free shoulder pad, arm, in addition, at the end of the long arm raznolikogo arm performed the recess for pressing on him at the opening, characterized in that it is provided with an additional raznolikim lever mounted on the same axis as the starting lever and covering long part of the shoulder, the arm, the long arm of the mentioned raznolikogo arm performed a longitudinal through slot in the plane of its rotation, and its short arm is made of two halves, separated through longitudinal slot and located at an angle to its long side, and provided with a roller, mounted on its end on the axis, with the possibility of contact with the notch of the long arm of the first raznolikogo arm, and the two halves of the short arm connected to the roller axis.2. Crane under item 1, characterized in that the housing is fixed siteplease element, and at the end of the shoulder pad of the lever from the rod locking member fixed flat spring, one end of which is fixed trigger interoperable with SitePlayer element.

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.
