Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of water hammer adsorber.
Background technique
Water pump is in starting with when stopping, the water impact pipeline, and a kind of serious water attack of generation, this water attack is called water hammer.Because inner at water pipe, inner tube wall is smooth, water flows freely.Suddenly close or the feed water pump parking when the valve of opening, current mainly are that valve or pump can produce a pressure to valve and tube wall.Because tube wall is smooth, follow-up current are under action of inertia, and it is maximum that waterpower reaches rapidly.Can cause pipe-line system judder, noise, and possibly destroy Valve joint, pipe-line system is produced very big destruction.
For solving the destruction that water hammer effect brings; People have invented a kind of water hammer adsorber; Can need not to stop under the mobile situation of fluid; Absorb the irregular water attack ripple concussion that all kinds of fluids are hammered into shape and surge takes place effectively outside the issuable water of transmission system, have destructive shock wave, play the purpose of protection thereby reach to eliminate.There is an airtight appearance air cavity inside of water hammer adsorber, and the lower end is a piston, and when shock wave imported the water hammer adsorber into, surge wave acted on the piston, and piston will be toward holding the motion of air cavity direction.The stroke of piston motion is relevant with gas pressure, surge wave size in holding air cavity; Piston is under the gas and irregular water attack double action of certain pressure; Move up and down, form a dynamic balance, so just eliminated irregular surge wave concussion effectively.
Patent Office of the People's Republic of China (PRC) provides a kind of water hammer adsorber [patent No. 94243489.7, notification number CN 220J558Y], and it mainly comprises closed nut, water hammer tube, piston ring, closed loop and tube head etc.Closed nut is screwed in screw thread on the end of water hammer tube, and to reach airtight effect, closed loop then is inserted in the airtight annular groove of piston ring, inserts in the pressure accumulation tube of water hammer tube again, again tube head is screwed togather the into the other end of water hammer tube subsequently.The water hammer of the utility model absorbs tube and is arranged in all kinds of pipelines, can eliminate vibrations unnecessary in the pipeline and retardance, and the position of its placement, quantity and specification etc. all can add change according to different pipelines.But do not have gas pressure in this water hammer adsorber, make piston ring in the pressure accumulation tube, bear less water hammer and just begin to slide that the effect of eliminating water hammer is undesirable.
Summary of the invention
The purpose of the utility model is to existing technical problem, has proposed a kind of elimination water hammer effect water hammer adsorber preferably.
The purpose of the utility model can realize through following technical proposal: a kind of water hammer adsorber, comprise tubular water hammer tube, and it is characterized in that; End closure in the described water hammer tube; Water hammer tube outer end is fixed with joint, has spool and plug in the described water hammer tube, and said spool is positioned at water hammer tube outer end; Described plug is positioned at the inner place of water hammer tube, has pressurized gas between spool in the described water hammer tube and the plug.
Joint is used for being connected with pipeline, also plays the effect of the outer end of sealing water hammer tube simultaneously.Pressurized gas are poured in the water hammer tube, make its give one of spool towards the outer end prescription to thrust, with plug the inner place of water hammer tube is sealed again, make the hyperbaric environment that forms a sealing in the water hammer tube.When the water hammer adsorber was received the water hammer effect of the fluid impact tube wall in the pipeline, water hammer made spool locate along the water hammer barrel towards the inner to move on spool.Spool moves reciprocatingly under the gas and irregular water hammer double action of high pressure, forms a dynamic balance, has so just eliminated irregular surge wave concussion effectively.
In above-mentioned water hammer adsorber, air pressure is 4MPa between spool in the said water hammer tube and the plug.In the water hammer tube, there are pressurized gas pushing the outer end that spool is pasting the water hammer tube constantly, make spool when bearing bigger water hammer, be not easy to slide to the plug direction, improved the elimination effect of water hammer adsorber up to 4MPa.
In above-mentioned water hammer adsorber, be provided with seal ring between described spool and the water hammer tube.Seal ring makes the spool outer rim can fit tightly on the inwall of water hammer tube, guarantees that the pressurized gas in the water hammer tube are not revealed away because of the gap that is compressed from here, improves the sealing between spool and the water hammer tube.
In above-mentioned water hammer adsorber, the said spool outside has recessed packing holder, and above-mentioned seal ring is positioned at the packing holder place.Packing holder can hold seal ring, makes seal ring be positioned at the spool outside always.
In above-mentioned water hammer adsorber, described spool one end has the surface of contact that is sphere, and the spool the other end has recessed cavity.The lifting surface area of cavity is big, and the resistivity that pressurized gas are bestowed on the spool is also big, makes spool can resist the impact force that strong water hammer produces.
In above-mentioned water hammer adsorber, described plug and water hammer tube have sealing gasket between the inner place.Sealing gasket has improved plug and the inner sealing effect of water hammer tube, makes pressurized gas be not easy to reveal away from both slits.
In above-mentioned water hammer adsorber, have recessed gasket base on the described plug, above-mentioned sealing gasket is positioned at the gasket base place.Owing to will in the water hammer tube, charge into pressurized gas; So earlier spool is put into water hammer tube outer end; Play the effect of sealed outer end place, charge into pressurized gas then, again plug and sealing gasket are put into the inner place of water hammer tube; Play sealing inner place effect, adopt necking down process to seal at place, the inner at last.
In above-mentioned water hammer adsorber, described joint comprises the joint that is complementary with the water hammer tube outside and has externally threaded connecting part that joint is enclosed within above-mentioned water hammer tube outer end and both are connected.The connecting part of joint can be connected with pipeline thread, and joint is enclosed within water hammer tube outer end and the sealing of water hammer tube is connected; Have the cascade passage in the middle of the joint, can block spool, the water hammer of pipeline can be arrived on the spool.
In above-mentioned water hammer adsorber, said joint joint and water hammer tube are fixed together through welding.Can the slit between joint joint and the water hammer tube be utilized scolder to fill through welding, improve the sealing effect at joint place.
In above-mentioned water hammer adsorber, said joint joint and water hammer tube are fixed together through soldering.
In above-mentioned water hammer adsorber, said joint joint and water hammer tube are fixed together through silver soldering.
Soldering, silver soldering all are after utilizing low-melting brazing metal heat fused, infiltrate the also welding method in gap, added metal spare joint, and tin, silver all have weldability preferably.
Compared with prior art, have the better seal environment in the water hammer tube of this water hammer adsorber, can hold pressurized gas, make spool when bearing bigger water hammer, be not easy to slide to the plug direction, improved the elimination effect of water hammer adsorber.
