(57) Abstract:Usage: sanitary-technical equipment. The inventive inlet and outlet are connected by a bypass, and the saddle is made with a through longitudinal slots. 1 C. p. F.-ly, 3 ill. The invention relates to the field of water supply and can be used in municipal and industrial water supply for regulating the pressure of water in buildings.Known pressure regulator water, consisting of a body with two seats, locking devices, made in the form of counterbalance valves, pivotally connected with a rod on the opposite end of which is fixed to the membrane arm of the reciprocating action with the cargo rests on the stem and node input lever in the housing of the device. The cavity of the regulator above the membrane connected to the pulse tube to the pipeline, which should be supported by the pressure of water (1).The drawback of such regulators is to configure the controller for a certain pressure after itself regardless of the conditions of demand. This leads to a waste of water during the night hours when the pressure in the building can be significantly reduced. In addition, defects in the security node of the input lever reciprocating in the housing of the device, under excessive pressure.The closest, to the technical essence and the achieved result to this invention is a device comprising a housing with inlet and outlet nozzles separated by a saddle and a stop element made in the form of gravitational valve mounted inside the housing (2).However, this device does not provide pressure regulation.The technical problem to be solved by the present invention is directed, is the reduction of water consumption during periods of maximum efficiency of water separation by reducing the pressure, and also simplify the design of the device by reducing the number of structural elements and perform whole body.The solution of this problem is achieved in that the pressure regulator water consists of a casing with inlet and outlet nozzles separated by a saddle, and a shut-off device. The body of the pressure regulator is made in the form of a hollow cylinder, in the saddle is a through longitudinal grooves, a locking device made in the form of gravitational valve mounted for movement within the casing, and inlet and outlet connection of odkai with holes, installed at the outlet port below the connection of the bypass outlet pipe.In Fig.1 shows a pressure regulator, a longitudinal section; Fig. 2 - cross section a-a of Fig. 3 section-CenturyThe pressure regulator water consists of a housing 1 with an inlet 2 and outlet 3 nozzles separated by a saddle 4, and the locking device 5, made in the form of gravitational valve that is installed with the possibility of vertical movement within the housing. In the saddle is a through longitudinal grooves 6. Inlet and outlet are connected by a bypass 7. At the outlet port below the connection to the bypass installed restrictive horizontal partition with apertures 8.The pressure regulator operates as follows. At low flow rates of water gravitational valve 5 is stationary in the saddle 4 and overlaps the main section of the device. The flow of water passing through a small section of the bypass 7 connecting the input 2 and output 3 nozzles of the device 1, and the grooves 6, feels great resistance, and the regulator, therefore, there is a large pressure loss, which significantly reduces the pressure after the regulator. With increased flow of water to the level of usable water is e, this gravitational valve 5 comes in a suspended state and is inside of the controller below the partition with holes 8 any provision, slightly constraining throughput section.The presence of the Governor of grooves and bypass reduces the pressure in the distribution network to the minimum necessary value that makes it possible to reduce wasteful water use, especially at night. 1. The pressure regulator water, consisting of a housing with inlet and outlet nozzles separated by a saddle and locking device made in the form of gravitational valve mounted inside the housing, wherein the inlet and outlet are connected by a bypass, and the saddle is made with a through longitudinal slots.2. The regulator under item 1, characterized in that at the outlet port below the connection of the bypass outlet pipe installed restrictive partition.
