Description

A reposition of redundant personnel stop valve for running water pipeline

Technical Field

The utility model belongs to the technical field of pipeline valve equipment, concretely relates to reposition of redundant personnel stop valve for water supply line.

Background

In the prior art, tap water refers to water which is produced after being purified and disinfected by a tap water treatment plant and meets the corresponding standard for people to live and produce. The domestic water mainly draws rivers, lakes, underground water and surface water through a water intake pump station of a water plant, is treated by the process flows of precipitation, disinfection, filtration and the like according to the national sanitary standards for drinking water for life by the water plant, and is finally conveyed to each user through a water distribution pump station. In the tap water pipe. The opening and closing part of the stop valve is a plug-shaped valve clack, the sealing surface is a plane or a conical surface, and the valve clack moves linearly along the center line of the valve seat. The stop valve, also called stop valve, is the most widely used valve, and it is popular because the friction between the sealing surfaces is small in the opening and closing process, it is durable, the opening height is not large, it is easy to manufacture, it is convenient to maintain, it is not only suitable for middle and low pressure, but also suitable for high pressure. The stop valve has the characteristics that: (1) the stop valve structure is simpler than the gate valve, and the manufacture and the maintenance are both more convenient. (2) The sealing surface is not easy to wear and scratch, the sealing performance is good, and the valve clack and the sealing surface of the valve body do not slide relatively when the valve is opened and closed, so that the wear and the scratch are not serious, the sealing performance is good, and the service life is long. (3) When the stop valve is opened and closed, the stroke of the valve clack is small, so that the height of the stop valve is smaller than that of the gate valve, but the structural length of the stop valve is longer than that of the gate valve. (4) The opening and closing torque is large, the opening and closing are laborious, and the opening and closing time is long. (5) The fluid resistance is large, and the power consumption is large because the medium channel in the valve body is more tortuous. (6) When the nominal pressure PN in the medium flowing direction is less than or equal to 16MPa, forward flow is generally adopted, and the medium flows upwards from the lower part of the valve clack; when the nominal pressure PN is more than or equal to 20MPa, the reverse flow is generally adopted, and the medium flows downwards from the upper part of the valve clack so as to increase the energy of the sealing element. When the stop valve is used, the medium of the stop valve can only flow in one direction, and the flow direction cannot be changed. (7) The valve flap is often eroded when fully open. When tap water is branched, a branch stop valve specially used for a tap water pipeline is needed.

Through retrieval, the Chinese patent with the publication number of CN208832121U discloses a shunt stop valve for a tap water pipeline, which comprises a valve body, wherein the valve body is provided with two joints, a first shunt pipeline is arranged on one joint of the valve body, a first pressure relief valve and a first switch valve are arranged on the first shunt pipeline, the first pressure relief valve is positioned between the first switch valve and the valve body, a first pressure gauge is arranged on the first pressure relief valve, and a first limit expansion joint is arranged at the outlet of the first shunt pipeline; and a second shunt pipeline is arranged on the other joint of the valve body, a second pressure release valve and a second switch valve are arranged on the second shunt pipeline, the second pressure release valve is positioned between the second switch valve and the valve body, a second pressure gauge is arranged on the second pressure release valve, and a second limit expansion joint is arranged at an outlet of the second shunt pipeline.

However, the water in the shunt pipe in the patent is required to be drained by the drainage mechanism, so that the shunt is inconvenient.
