Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline systems, and in particular to a detachable water hammer buffer support. Background Technology
[0002] As is well known, when a valve suddenly closes or a water pump suddenly stops operating during normal operation of a water supply pipeline, the inertia of the water flow will exert a strong impact force on the valve and pipeline, causing a sudden increase in pressure in the closed pipeline system. This results in noticeable swaying and shaking of the pipeline, accompanied by a "bang, bang, bang" sound similar to a hammer striking the pipe. In hydraulics, this phenomenon is called the "water hammer effect." The water hammer effect is highly dangerous; the instantaneous pressure it generates can reach several times or even tens of times the normal operating pressure, potentially leading to pipeline rupture, equipment damage, and even personal injury accidents. It is a phenomenon that cannot be ignored in pipeline systems.
[0003] In existing technologies, rubber expansion joints are typically installed at the inlet end of valves to provide a buffering effect; or rigid supports are used to fix the pipeline. While the former can absorb some pressure fluctuations when water hammer occurs, it may still cause severe pipeline vibration, leading to loosening of joints or equipment damage; the latter lacks elastic buffering when water hammer occurs and has drawbacks such as difficult maintenance and insufficient vibration reduction.
[0004] Based on this, this application provides a detachable water hammer buffer bracket with good shock absorption and convenient maintenance to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art. To this end, the present invention provides a detachable water hammer buffer bracket with good shock absorption effect and convenient maintenance.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A detachable water hammer buffer support is provided for supporting rubber expansion joints in a pipeline system. It includes a support surface, connectors, uprights, a shock-absorbing sleeve, and expansion bolts. The support surface is formed by two symmetrically arranged support units joined together by the connectors. The two support units are fastened to the outside of the rubber expansion joint, and both are provided with mounting holes for bolt connection to the flange of the rubber expansion joint. The tops of the two uprights are welded to the outer center of the two support units, and the shock-absorbing sleeve is detachably installed at the bottom. The shock-absorbing sleeve consists of a sleeve, a pad, and a shock-absorbing mat arranged sequentially from top to bottom. The sleeve is fitted onto the uprights, and the pad is welded to the bottom of the sleeve. Both the pad and the shock-absorbing mat have through holes in their middle sections. The shock-absorbing sleeve is fixedly installed on the equipment foundation or the ground using expansion bolts.
[0008] In some alternative embodiments, the support unit is an "L" shape welded from two galvanized angle steels, and the upper and side surfaces at both ends of the two support units are connected to the connectors by bolts.
[0009] In some alternative embodiments, the connector is a triangular connector, which is welded from three mutually perpendicular steel plates.
[0010] In some alternative embodiments, the upright is made of galvanized square steel with an outwardly inclined cut at the top and a sealing plate welded to the cut.
[0011] In some alternative embodiments, the shock-absorbing pad and the pad plate are bonded together with a rubber-type elastic adhesive.
[0012] In some alternative implementations, the damping pad is a rubber damping pad.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model uses a rigid support frame formed by a support bracket, uprights, and shock-absorbing sleeve to fix the rubber expansion joint to the equipment foundation or ground, which can effectively solve the problem of joint loosening caused by severe vibration of the pipeline during water hammer effect; at the same time, the shock-absorbing sleeve and the rubber expansion joint form a dual shock absorption mechanism, which uses its elastic deformation to absorb the impact energy of water hammer effect, effectively reducing the vibration of pipeline and support, and improving the safety of pipeline system.
[0015] 2. The bracket support surface adopts a split structure design, which is convenient for disassembly and assembly and easy for maintenance; and the bracket support surface is made of angle steel welded together, which is simple to manufacture and low in cost. Attached Figure Description

It includes a support surface 1, a connector 2, a vertical rod 3, a shock-absorbing sleeve 4, and expansion bolts, wherein:
[0030] The support surface 1 is formed by two symmetrically arranged support surface units 1a joined together by connectors 2. In a preferred embodiment, each support surface unit 1a is an "L" shape welded from two galvanized angle steels. The upper surfaces and sides of both ends of the two support surface units 1a are bolted to the connectors 2. Correspondingly, the connectors 2 are triangular connectors, which are welded from three mutually perpendicular steel plates. After the two support surface units 1a are joined together, they are fixed by two connectors 2, and the upper surfaces of both support surface units 1a are provided with mounting holes 1a.1 for bolted connection to the flanges of the rubber expansion joint 10.
[0031] Two uprights 3 are provided, with their tops welded to the outer center of the two support units 1a respectively. The bottom of each upright is detachably fitted with a shock-absorbing sleeve 4. In this embodiment, the detachable type is a plug-in connection, i.e., the upright is inserted into the shock-absorbing sleeve. In a preferred embodiment, the upright 3 is made of galvanized square steel, with an outwardly inclined cut at its top, and a sealing plate 3.1 welded to the cut. This design creates a sloping surface on the top of the upright, improving its aesthetics.
[0032] As attached Figure 1 To be continued Figure 3 As shown, the shock-absorbing sleeve 4 consists of a sleeve 4.1, a pad 4.2, and a shock-absorbing pad 4.3 arranged sequentially from top to bottom. The sleeve 4.1 is sleeved with the upright 3, and the pad 4.2 is welded to the bottom of the sleeve 4.1. Both the pad 4.2 and the shock-absorbing pad 4.3 have through holes in their middle sections. The shock-absorbing sleeve 4 is fixedly installed on the equipment foundation or the ground using expansion bolts. Preferably, in this embodiment, the shock-absorbing pad 4.3 is a rubber shock-absorbing pad.
[0033] In a preferred embodiment, the shock-absorbing pad 4.3 and the pad plate 4.2 are bonded together with a rubber-type elastic adhesive. The rubber-type elastic adhesive is preferably an HR series rubber-reinforced adhesive, such as HR-330, HR-380, etc., which is suitable for flexible bonding of rubber and metal and has the characteristics of impact resistance and peel resistance after curing.
[0034] In specific implementation, see attached Figure 4As shown, fixed holes are drilled at predetermined positions on the equipment foundation or ground. The shock-absorbing sleeve is fixed to the equipment foundation or ground using metal expansion bolts. The uprights of the two support units are inserted into the shock-absorbing sleeves respectively. The mounting holes on the two support units are aligned with the upper flange holes of the rubber expansion joint. During connection, the bolts pass through the upper flange holes of the rubber expansion joint and the mounting holes of the support units in sequence from the pipe flange above the rubber expansion joint. Then, the two support units are connected into one piece by two connectors, so that the two support units are fastened to the outside of the rubber expansion joint. This completes the installation of the bracket.
