Abstract
The utility model provides a water eliminating hammer device which is formed by a pipeline, a flange disc, a valve body, a valve core, a valve core end cover, a sealing washer, a baffling block, a resetting spring, a valve core spring and a gasket. The valve core end cover is provided with an end cover through hole; the valve body is provided with a valve body through hole; a channel is arranged between the valve body and the pipeline; and a through hole is formed between a bidirectional valve outlet and the channel. When the valve is switched on, a medium flows in from an inlet of a bidirectional valve; the valve core end cover is pushed and the resetting spring buffers pressure caused by medium impact; when the valve core end cover is continually pressed and the valve body through hole is opened, the medium flows out from the valve body through hole and enters the channel; then the medium in the channel flows to an outlet of the bidirectional valve from the through hole; when the valve is switch off, the medium flows back from the outlet of the bidirectional valve and flows through the end cover through hole to push the baffling block; and the impact pressure formed by reflowing the medium is buffered by the valve core spring. The water eliminating hammer device disclosed by the utility model has the advantages that the water attack of a water hammer can be reduced and the structure is simple.
Description
Technical field
The utility model relates to a kind of water-hammer device that disappears, and is widely used in the water supply pipe net systems such as tall building, living area and town water supply engineering.
Background technique
In the pipeline of sealing, when medium the utmost point in the short time flow velocity improve suddenly or reduce, water hammer can appear, it is usually by the unexpected unlatching of valve, water tap or water pump or close and cause.Water hammer can cause the extension of superpressure and negative pressure in pipeline, therefore produces the even damage of system element of huge noise.
Therefore the superpressure that increases on existing hydraulic pressure basis in pipeline can cause following problem:
Pipeline, the breakage of water tank and flexible pipe.
Soft in system connects, the welding portion wearing and tearing.
The damage of stop valve, safety check, modulating valve.
Huge noise and vibrations in pipeline.
The superpressure value is affected by the multiple systems factor, such as:
The watering equipment shut-in time.
Pipe material, bore and length.
Water velocity.
The model utility content
The utility model provides a kind of water-hammer device that disappears for solving the impact of above-mentioned water hammer, can reduce the generation of water hammer water attack, and is simple in structure.
The utility model adopts following technological scheme:
The water-hammer device that disappears is comprised of pipeline, flange plate, valve body, spool, spool end cap, seal washer, block, Returnning spring, valve core spring and pad.
Described pipe ends mounting flange has a two-way valve in pipeline, two-way valve one end is placed on the interior cylindrical support dish of pipeline, and the other end is fixed on valve body in pipeline with nut.Be mounted with Returnning spring in described valve body, spool end cap and valve body fixed reset spring.Described valve core spring one end is fixed on spool with pad, and the other end is close to the spool end cap.Described spool one end is connected with block, and block and spool are with being integrated, and block is cylindrical, and the centre has cylinder shape groove, makes the spool end cap can embed in groove, between spool end cap and supporting disk, seal washer is arranged.
Have the end cap through hole on described spool end cap, have valve hole on valve body, between valve body and pipeline, passage is arranged, between two-way valve outlet and passage, through hole is arranged.
When valve opening, medium flows into from the two-way valve entrance, promotes the spool end cap, the pressure that the Returnning spring buffer medium impacts is when spool end cap continuation pressurized, when opening valve hole, medium flows out inlet passage from valve hole, and the medium in passage flows to the two-way valve outlet from through hole again.
When valve closing, medium refluxes from the two-way valve outlet, and the end cap through hole of flowing through promotes block, the pressure that impacts when the valve core spring buffer medium refluxes.
The utility model has the advantages that: can reduce the generation of water hammer water attack, simple in structure.
