Problems solved by technology

However, the pressure reducing valves connected to the existing pipelines, such as diaphragm pressure reducing valves, have complex internal structures and large volumes, and are not suitable for installation on pipelines on floors. The number of settings on the floor is often limited, but if the floor is too high, the pressure to be output is high. If there is not a sufficient number of decompression equipment, there are still potential safety hazards

Abstract

The invention discloses a pressure reducing valve device in a water supply hydraulic system. The pressure reducing valve device comprises a pressure reducing valve body. A water inlet pipeline and a water outlet pipeline are respectively arranged at two ends of the pressure reducing valve body, an inner cavity, a water storage bin and a channel are arranged in the pressure reducing valve body, the water storage bin is communicated with the water outlet pipeline, a handle which runs through the inner cavity is arranged on the top of the pressure reducing valve body, a spiral spring is vertically arranged in the inner cavity, one end of the spiral spring is connected to the handle, a membrane is connected to the other end of the spiral spring, a cylindrical bar which is vertically arranged is connected to the bottom of the membrane, an elastic clamp plate is connected with the cylindrical bar, a rubber plate is arranged on the elastic clamp plate, a tension spring which is fixed onto the wall of the inner cavity is connected to the bottom of the elastic clamp plate, and a spray pipe is communicated with the water inlet pipeline via the channel in the pressure reducing valve body. The pressure reducing valve device in the water supply hydraulic system has the advantages of simple structure, small size and excellent safety performance.

Description

technical field [0001] The water supply hydraulic equipment of the present invention particularly relates to a pressure reducing valve device in a water supply hydraulic system. Background technique [0002] With the acceleration of the urbanization process to save land, the floors gradually increase, which undoubtedly brings a lot of inconvenience to the urban water supply, which requires the secondary water supply of the water supply pump group. However, the water supply pump group is opened and stopped, accompanied by valve The opening and closing of the water hammer will cause water hammer phenomenon in the tap water. The water hammer may be several times, ten times, or even dozens of times greater than the water supply pressure, so the consequences of this phenomenon will be very serious. Therefore, the pipeline uses A special decompression device is very necessary; the decompression device not only has a decompression effect, but also has a pressure stabilizing effect....
