Abstract
The utility model relates to a two unfamiliar attenuators of reverse formula with conveying system is thrown to the displacement pump, belongs to trade fields such as oil, chemical industry, electric power, food and beverage, papermaking and water treatment. The utility model discloses by the last attenuator body, down the attenuator body, go up diaphragm, lower diaphragm plate, inflation valve, O and appear circle, round nut, screw, nut and gasket and constitute. It has mainly utilized technical measures such as unfamiliar subassembly, aerating device and attenuator cavity structures, is applied to this two unfamiliar attenuators of reverse formula to diaphragm technique, the technique of aerifing and sealed principle, realizes two unfamiliar attenuator compressed gas's preliminary filling, isolation, pulsation sealed and that overflow the medium and eliminates.
Description
Technical field
This utility model relates to a kind of double diaphragm damper of reverse type adding induction system for displacement pump, is installed on pipeline for eliminating pipeline liquid pulsation, belongs to the industry fields such as oil, chemical industry, electric power, food and drink, papermaking and water process.
Background technology
The type structure of current existing field correlation technique is to be realized the isolation of gas and medium by the single barrier film in diaphragm damper.The shortcoming of this kind of structure is the isolation being not carried out antivibrator housing with medium, and shell material needs to meet corrosion-resistant requirement.
Summary of the invention
It is an object of the invention to provide a kind of novel double diaphragm damper of reverse type adding induction system for displacement pump, be that the one to original common diaphragm antivibrator is supplemented, to adapt to the needs (such as Fig. 1) of antivibrator housing and medium isolation.
This utility model solves its technical problem and be the technical scheme is that this double diaphragm damper of reverse type adding induction system for displacement pump includes: above damp body, bottombearing damper body, upper barrier film, lower diaphragm plate, charge valve, O, round nut, screw, nuts and washers.Upper barrier film be superimposed together composition one inversion air bag relative with lower diaphragm plate, the interface of lower diaphragm plate is metal material, and it is embedded as a whole with the barrier film of quality of rubber materials and is directly mounted at exterior line.The interface of lower diaphragm plate leans out bottombearing damper body, realizes being locked by being enclosed within the round nut above it.Upper barrier film central top inlays an iron core, plays the effect of limiting plate, prevents barrier film from extruding from the interface of lower diaphragm plate under gas pressure effect.Upper damping body is connected fastening with bottombearing damper body by border screw, and compresses the realization sealing of upper and lower diaphragm edge.Charge valve is by being threadably mounted at upper damping body upper end and compressing following O and realize the sealing of gas in antivibrator housing.The compressed gas entered from charge valve is directly entered in antivibrator housing.The operation principle of the double diaphragm damper of this reverse type is: flow velocity being had to the pipe-line system of sine curve characteristic, during crest, pressure increases, and the medium in pipeline enters the air bag that upper and lower barrier film is constituted, and air bag cavity volume becomes big, absorbs the liquid of excess traffic；During trough, pressure diminishes, and air bag is compressed under gas pressure effect, and air bag cavity volume diminishes, the liquid of release storage, thus reaches to eliminate the effect of pulsation.
The double diaphragm damper of reverse type adding induction system for displacement pump that this utility model provides, it provides the benefit that:
Compared with existing common diaphragm antivibrator, have reduce because the isolation of antivibrator housing and media implementation its material require and have owing to being equipped with the assembled air bag of double barrier film easily fabricated, seal reliable advantage.
Accompanying drawing explanation
Fig. 1 is the section of structure of the double diaphragm damper of this utility model reverse type.
Detailed description of the invention
In FIG, 1-charge valve, 2-O shape circle, 3-damps body, the upper barrier film of 4-, 5-lower diaphragm plate, 6-round nut, 7-bottombearing damper body, 8-nut, 9-packing ring, 10-screw.
Upper barrier film 4 be superimposed together composition one inversion air bag relative with lower diaphragm plate 5, the interface of lower diaphragm plate 5 is metal material, and it is embedded as a whole with the barrier film of quality of rubber materials and is directly mounted at exterior line.The interface of lower diaphragm plate 5 leans out bottombearing damper body 7, is locked by being enclosed within the round nut 6 above it.Upper damping body 3 is connected fastening with bottombearing damper body 7 by the screw 10 of border, nut 8 and packing ring 9, and the edge compressing upper barrier film 4 and lower diaphragm plate 5 realizes sealing.Charge valve 1 realizes preliminary filling and the sealing of gas by being threadably mounted at upper damping body 3 upper end and compress following O 2.
Claims (2)
1. the double diaphragm damper of reverse type, it is characterized in that the double diaphragm damper of this reverse type is made up of upper damping body, bottombearing damper body, upper barrier film, lower diaphragm plate, charge valve, O, round nut, screw, nuts and washers, it is characterized in that: upper barrier film be superimposed together composition one inversion air bag relative with lower diaphragm plate, the interface of lower diaphragm plate is metal material, and it is embedded as a whole with the barrier film of quality of rubber materials and is directly mounted at exterior line；The interface of lower diaphragm plate leans out bottombearing damper body and fastens with round nut；Upper damping body is connected fastening with bottombearing damper body by border screw, nut, packing ring, and is compressed upper and lower diaphragm edge；Charge valve is by being threadably mounted at upper damping body upper end and compressing following O, and the compressed gas entered from charge valve is directly entered in antivibrator housing.
The double diaphragm damper of reverse type the most according to claim 1, it is characterized in that upper barrier film (4) the be superimposed together air bag that constitute relative with lower diaphragm plate (5) is inverted in the cavity of the double diaphragm damper of reverse type, the edge of upper barrier film (4) and lower diaphragm plate (5) is compressed by screw (10), nut (8) and packing ring (9) and damps body (3) and bottombearing damper body (7) and realize fixing.
