Abstract
The utility model relates to a piston-type water-hammer arrestor and provides a piston-type water-hammer arrestor which is novel in structure design, reliable in performance, long in service life, and convenient to maintain, and can effectively release or remove water attack or impact caused by a water hammer. The piston-type water-hammer arrestor comprises a cylinder block with a sealing container cavity, and a piston; the cylinder block comprises an impact port connected with a pipeline; the piston is arranged inside the sealing container cavity of the cylinder block in the manner of moving up and down; a lock cover for preventing the piston from moving up and down is also arranged at the impact port of the cylinder block; a needle valve for filling gas into the sealing container cavity of the cylinder block according to the pressure size of the pipeline to achieve the required pressure of the pipeline is also arranged at the upper part of the cylinder block, and a pressure gage for displaying the pressure of an air chamber of the valve body before installation and displaying the pressure of the pipeline after installation is arranged on the needle valve.
Description
Technical field
The utility model relates to a kind of water-hammer arrester, particularly a kind of piston type water hammer canceller.
Background technique
In water system, owing to water pump breaks down or has a power failure suddenly reason, current are ended suddenly, water hammer can occur when water began to flow backwards, its reason is because liquid has kinetic energy when mobile in pipe, when refluence liquid cut, its kinergety must be eliminated, these energy are into the high pressure wave that is begun by halt, and fill vacancies in the proper order to passback along pipe-line system, liquid in pipe is expanded outwardly expand and the bump pipeline, thereby cause water hammer, pipeline can produce vibrations or wave and send ear-piercing noise in these cases, when serious even the destruction that can cause valve or pipeline, causes whole drainage system paralysis.
The existing technical staff eliminates the method for water hammer, after the water pipe internal pressure surpasses certain value, drain opening is opened, a part of water is flowed out, but when alleviating water flow impact pressure, also wasted great lot of water resources, in order better to eliminate the water hammer that produces in the pipeline, various water hammer abatement apparatus have appearred in prior art, the equipment of solution water hammer commonly used is the water hammer of glue courage formula air bag water-hammer arrester or the elastic rubber tube structure device that disappears, this water-hammer arrester is to utilize the contraction or expansion of air bag and elastic rubber tube to eliminate impact that current bring, although also can play the effect of eliminating water hammer, but under impacting than mass-flow, the inefficacy thereby air bag and elastic rubber tube very easily break, this water-hammer arrester poor reliability, working life is short, whole absorber will be removed during repairing just can place under repair.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of structural design novel, can effectively alleviate or eliminate impact, reliable performance, long service life and piston type water hammer canceller easy to maintenance that water attack or water hammer bring.
For solving this technical problem, the utility model is taked following scheme: a kind of piston type water hammer canceller, comprise the cylinder body with seal container chamber, piston, described cylinder body has the Striker end that is connected with pipeline, but being located in the airtight container chamber of cylinder body of described piston knee-action, the Striker end of described cylinder body also is provided with the locking closure that prevents that piston from moving downward, described cylinder body top also is provided with and can be filled with gas to reach the needle type valve of the required pressure of pipeline to cylinder body seal container chamber according to the pipeline pressure size, and described needle type valve shows the valve body air chamber pressure before being provided with and installing, the pressure gauge of display pipes pressure after installing.
Further improvedly be: be provided with seal ring between described piston and the inboard wall of cylinder block.
By adopting the aforementioned techniques scheme; the beneficial effects of the utility model are: when shock wave imports cylinder body into from the Striker end of cylinder body; surge wave acts on the piston; piston will move toward the container chamber direction; gas pressure in the stroke of piston movement and the container chamber; the surge wave size is relevant; piston is under the gas and irregular water attack double action of certain pressure; move up and down; form a dynamic balance; thereby effectively eliminate the irregular water attack ripple concussion that all kinds of fluids are hammered into shape and surge occurs outside the issuable water of transmission system; thereby reach to eliminate and have destructive shock wave; play the purpose of protection; its structural design is new reasonable; can effectively alleviate or eliminate the impact that water attack or water hammer bring; piston cylinder operator is applicable to the impact of mass-flow; air bag and elastic rubber tube can not occur breaks and affects the problem of water-hammer arrester work; this water-hammer arrester reliable working performance; long service life; the locking closure of piston bottom only need outwarded winding during repairing just can be changed or repair piston, and is easy to maintenance.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Now with specific embodiment the utility model is further specified by reference to the accompanying drawings.
With reference to figure 1, the utility model discloses a kind of piston type water hammer canceller, comprise the cylinder body 1 with seal container chamber 11, piston 2, described cylinder body 1 has the Striker end 12 that is connected with pipeline, but being located in the airtight container chamber 11 of cylinder body 1 of described piston 2 knee-actions, the Striker end 12 of described cylinder body 1 also is provided with the locking closure 4 that prevents that piston 2 from moving downward, described cylinder body 1 top also is provided with and can be filled with the needle type valve 3 of gas to reach the required pressure of pipeline to cylinder body seal container chamber according to the pipeline pressure size, described needle type valve 3 shows the valve body air chamber pressure before being provided with and installing, the pressure gauge 31 of display pipes pressure is provided with seal ring 5 between described piston 2 and cylinder body 1 inwall after installing.
When shock wave imports cylinder body into from the Striker end of cylinder body; surge wave acts on the piston; piston will move toward the container chamber direction; gas pressure in the stroke of piston movement and the container chamber; the surge wave size is relevant; piston is under the gas and irregular water attack double action of certain pressure; move up and down; form a dynamic balance; thereby effectively eliminate the irregular water attack ripple concussion that all kinds of fluids are hammered into shape and surge occurs outside the issuable water of transmission system; thereby reach to eliminate and have destructive shock wave; play the purpose of protection; its structural design is new reasonable; can effectively alleviate or eliminate the impact that water attack or water hammer bring, piston cylinder operator is applicable to the impact of mass-flow, air bag and elastic rubber tube can not occur and break and affect the problem of water-hammer arrester work; this water-hammer arrester reliable working performance; long service life, the locking closure of the piston bottom of only need outwarding winding during repairing just can be changed or repair piston, and is easy to maintenance.
The above record, only for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
