Abstract
The utility model discloses a diaphragm type pulse damper. The diaphragm type pulse damper comprises a gas storage chamber, an elastic diaphragm and a connecting pipe, wherein the elastic diaphragm divides the gas storage chamber into a working medium cavity and a gas compression cavity; the connecting pipe is communicated with the working medium cavity; a diaphragm is flat-plate type; two sides of the diaphragm are respectively provided with a limiting plate; a diaphragm deformation space is formed between the limiting plate and the diaphragm; a plurality of through holes are arranged in the limiting plates; when the diaphragm type pulse damper is used, a working medium and an inert gas can pass through the through holes in the limiting plates to reach two sides of the diaphragm so as to act mutually; and the energy is stored and released by diaphragm deformation. Since the deformation degree of the diaphragm is limited by the limiting plates, the condition that the deformation amount of the diaphragm is overlarge so as to cause damage of the diaphragm due to overlarge pressure can be effectively prevented, and the reliability and the fatigue life of the diaphragm are effectively guaranteed; in addition, the diaphragm is made of a PTFE (polytetrafluoroethylene) material with strong wear resistance and can be used for relieving the pressure and flow pulsation of a conveying pipeline of an organic-solvent with strong polarity.
Description
Technical field
The utility model relates to the fluid delivery tube circuit component, particularly a kind of pipeline parts that is used for mild pipeline flow and pressure pulsation.
Background technique
Be in the fluid delivery system of power with the reciprocating pump; To produce flow and pressure pulsation inevitably owing to the reciprocating pump performance characteristic; All will have a negative impact to system equipment and technological process, even threaten the Security and the reliability (sucking the fault open of end cavitation, water hammer, safety valve like pump) of system itself and whole process flow.Ripple damper is installed in pipe-line system, can be effectively reduced flow and pressure pulsation value, weaken shock and vibration pipe-line system.Ripple damper utilizes the compressibility of gas to store and releases energy, and reaches the effect of elimination by caused impact of reciprocating pump and pulsation.When pump was in discharge process, the part medium got into the damper chamber, and the compression intracavity gas is in energy savings process; When pump was in the imbibition process, the part medium was pushed back pipeline, replenished piping flow, was in the energy releasing course; Thereby play the effect of mild system pressure pulsation and flow pulsation.
Existing air bag prepressing type ripple damper structure is as shown in Figure 3, comprises gas storage chamber, diaphragm 2, bolt, connecting tube 3 and gas charging valve, and diaphragm is divided into working medium chamber 1a and gas compression chamber 1b with gas storage chamber.This damper only needs little of gas just can reach the remaining pulsation of ideal system requirement; Working medium does not contact with gas and possible chemical reaction takes place, and has guaranteed the reliability of manufacturing process; Working medium can not take place to reveal and jeopardize and produce and personal safety.But; Still there is deficiency in existing air bag prepressing type ripple damper, owing to utilizing the compressibility of gas to store, releasing energy, reaches the effect of damping by caused impact of reciprocating pump and pulsation; The air bag of the inner cavity chamber's shape of walking back and forth is adopted in the inert gas of inner chamber and the isolation of solution; Air bag is done tired to-and-fro motion in chamber, and amount of deformation is big, and this has just produced following requirement to bag material: 1, have the corrosion resistance to fed sheet of a media; 2, good ductility and elasticity; 3, can carry out long tired to-and-fro motion.And the bag material that adopts at present has: various synthetic rubber such as nitrile butadiene rubber, fluorine rubber, the bright rubber of ternary second; These rubber can not be resisted the dissolving of strong polar organic solvent; The consequence of dissolving is to guarantee the operation of long-time system reliably; Also inevitably cause working medium to pollute, this has just caused in some strong polarity chemical-process medium transport, can not using existing air bag prepressing type ripple damper.
To above-mentioned deficiency, need to explore a kind of ripple damper, make it can long-time tired to-and-fro motion, in addition, also can be used for the pressure and the flow pulsation of mild some strong polar organic solvent metering delivery pipeline system.
The model utility content
In view of this; The utility model provides a kind of diaphragm type ripple damper; This damper utilizes limiting board to come the deformation extent of limiting diaphragm; Reach the reliability of assurance diaphragm and the purpose of fatigue life, in addition, this damper also can be used for the pressure and the flow pulsation of mild strong polar organic solvent delivery line.
The diaphragm type ripple damper of the utility model; Comprise gas storage chamber, gas storage chamber is divided into the flexible sheet of working medium chamber and gas compression chamber and the connecting tube that is communicated with the working medium chamber; Said diaphragm is flat; The both sides of diaphragm be provided with respectively and diaphragm between form the limiting board in diaphragm deformation space, a plurality of through holes are set on the said limiting board.
Further, said diaphragm is processed by teflon;
Further, said limiting board is a sphere curved surface near a side of diaphragm;
Further, said gas storage chamber is two and each other butt joint, the spatial communication between the said connecting tube diaphragm corresponding with two gas storage chambers;
Further, be interconnected between the gas compression chamber that said two gas storage chambers are corresponding.
The beneficial effect of the utility model: the diaphragm type ripple damper of the utility model has the following advantages:
1) under the situation that does not reduce the ripple damper chamber size, adopt flat diaphragm and adopt the deformation extent of limiting board limiting diaphragm, both guaranteed the reliability and the fatigue life of diaphragm, prevent the excessive damage that causes diaphragm of system pressure again.
2) select teflon sheet material as the material of isolating working medium and pressed gas; Corrosion resistance is strong; Can be used for the pressure and the flow pulsation of mild strong polar organic solvent delivery line; Physical property according to teflon sheet material is carried out ripple damper structural design, more reasonable structure, more reliable performance.
3) manufacturing process is more simple, and flat diaphragm design has solved the difficult problem that air bag is made fully;
4) the gas storage chamber volume is little with the ratio of the weight of whole damper, and under the identical remaining ripple factor requirement condition, the utility model volume is littler, and weight is lighter;
5) but both Manufacture Order chamber product of the utility model utilizes identical parts also can carry out the dual cavity expansion, produce the product of different size, highly versatile.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model;
