Rubber container airbag-type water hammer absorber for waterway pipe network

Abstract

The invention relates to the field of water hammer elimination equipment, and discloses a rubber container airbag-type water hammer absorber for a waterway pipe network. The rubber container airbag-type water hammer absorber comprises a pipe body, wherein an upper sliding plate movably sleeves the top of an inner cavity of the pipe body; a through hole is formed in the upper sliding plate; a hammer suction pipe is fixedly connected to the middle of the bottom end of the pipe body; a bottom flange of the hammer suction pipe is connected with a compensation pipe; the compensation pipe communicates with the waterway pipe network; and the bottom of the inner cavity of the pipe body is fixedly sleeved with a lower annular plate located above the compensation pipe. Through the structural design that the hammer suction pipe and the upper sliding plate in the pipe body can move downwards as a whole, a passive sealing block on the hammer suction pipe and a positioning sealing ring fixedly sleeving the the side wall of the inner cavity of the pipe body are matched to clamp a rubber container airbag, so that normal pipeline water hammer elimination is not affected, and when water pressure generated by a water hammer is too large, the passive sealing block can move downwards to be separated from the positioning sealing ring, so that water drainage and pressure relief are carried out, and the expansion of the rubber container airbag is effectively protected.

Description

technical field [0001] The invention relates to the field of water hammer elimination equipment, in particular to a rubber bladder airbag type water hammer absorber used for waterway pipe networks. Background technique [0002] It is a hydraulic protection device that buffers water hammer by sealing the air pressure chamber, and can prevent building water supply pipes and facilities from being damaged by water hammer. The existing water hammer absorbers include piston type and rubber bladder airbag type. When there are many solid impurities in the pump, the piston is easily affected by the impurities and has a low service life. Therefore, the rubber bladder airbag water hammer eliminator is often used in pipe networks with poor water quality. [0003] The bladder airbag type water hammer eliminator is mainly composed of a tube body, a suction hammer tube and a rubber bladder airbag. Gas with a certain strength, when in use, when the water shock wave generated by the water h...

Problems solved by technology

[0004] However, when the existing bladder-type water hammer eliminator is in use, when the water pressure generated by the water hammer is too large, it is easy to cause the bladder bladder to over-expand and burst and fail, and the service life is short. In terms of the way of rubber bladder air bag protection, pressure relief needs to be supplemented with air, which makes the later use troublesome. Therefore, a rubber bladder air bag type water hammer absorber for water pipe network is provided to solve the above-mentioned problems. technical problem
