Abstract
The utility model discloses a relief valve silencer is used in chemical plant, including silencer barrel, baffle, through -hole, upper cover, lug, support, base, low head and air inlet, silencer barrel both ends are provided with upper cover and low head, be provided with the lug on the upper cover, evenly be provided with the through -hole on the silencer barrel outer wall, the support sets up and lean on the lower extreme outside the silencer barrel, the low head lower extreme is provided with the air inlet, the beneficial effects of the utility model are that: this kind of relief valve silencer is used in chemical plant simple structure, compactness are and equitable, and convenient assembling is swift, connect reliable, thereby through the air current of upsetting the silencer and the purpose that the sound wave reaches the noise elimination, reduced the noise, it is smooth and easy that the exhaust is advanced to inside, power consumption is little, noise suppression effect is good, has improved the reliability of silencer work greatly, the easy to use is promoted, makes the blast pipe can not bear great external force because of settling the muffler, disintegrates that it is convenient to examine and repair, the discharge capacity, the take -off that do not influence the relief valve reach back.
Description
Technical field
The utility model relates to the one of noise elimination clothing arts, is specifically related to a kind of chemical plant safety valve silencing apparatus.
Background technique
Chemical plant safety valve silencing apparatus is a kind of silencing apparatus, be mainly used in electric power, chemical industry, safety valve in the industries such as metallurgy, effective noise elimination of the high temperature and high pressure steam discharge of Pcv valve and exhaust steam valve, for boiler safety door and exhaust steam valve, it can look at is a constituent element of pipeline, after Acoustic treatment is made in inside, generation and the propagation of noise can be weakened, outlet silencing noise amount is made to reach 20 ∽ 30 decibels (A sound level), correspondingly loudness reduces by more than 50%, subjective sensation has positive effect, silencing apparatus is the device of abatement pneumatic noise, installed in the duct or enter, on relief opening, while air-flow passes through, to noise, there is certain consumption.Existing silencing apparatus is because complex structure, weight are large, high temperature oxidation sound absorption filler, high velocity air impacts sound absorption filler, the reasons such as aqueous vapor infiltration sound absorption filler, silencing apparatus is easy to occur that maintenance is frequent, soundproof effect is poor, the situations such as life cycle is short, soundproof effect is poor, and intake and exhaust resistance is larger, air flow property is poor, greatly reduces the reliability of silencing apparatus work.
Model utility content
The purpose of this utility model is just to provide a kind of chemical plant safety valve silencing apparatus to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of chemical plant safety valve silencing apparatus, comprise silencer cylinder, dividing plate, through hole, upper cover, hanger, bearing, base, lower seal head and suction port, described silencer cylinder two ends are provided with upper cover and lower seal head, described upper cover is provided with hanger, described silencer cylinder outer wall is evenly provided with through hole, outside silencer cylinder on lower side, described lower seal head lower end is provided with suction port to described bearing settlement.
Further, described silencer cylinder inside is provided with multiple dividing plate, and the opening of dividing plate is not on the same line and vary in size.
Further, described diaphragm internal is filled with sound absorption cotton.
Further, described arrays of openings triangularity or rectangular.
Further, described silencer cylinder bottom is provided with base.
The beneficial effects of the utility model are: this chemical plant safety valve acoustic wave filter structure is simple, compact and reasonable, fast easy to assembly, connect reliable, by upsetting the air-flow of silencing apparatus and sound wave thus reaching the object of noise elimination, reduce noise, inner intake and exhaust are smooth and easy, power loss is little, soundproof effect is good, substantially increasing the reliability of silencing apparatus work, be easy to use and promote, making outlet pipe can not bear larger external force because settling baffler, Disintegration overhaul is convenient, does not affect the discharge capacity of safety valve, take-off and returns seat.
Accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
In figure: 1, silencer cylinder, 2, dividing plate, 3, through hole, 4, upper cover, 5, hanger, 6, bearing, 7, base, 8, lower seal head, 9, suction port.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
1 describe by reference to the accompanying drawings, a kind of chemical plant of the utility model safety valve silencing apparatus, comprise silencer cylinder 1, dividing plate 2, through hole 3, upper cover 4, hanger 5, bearing 6, base 7, lower seal head 8 and suction port 9, described silencer cylinder 1 two ends are provided with upper cover 4 and lower seal head 8, described upper cover 4 is provided with hanger 5, described silencer cylinder 1 outer wall is evenly provided with through hole 3, described bearing 6 to be arranged on outside silencer cylinder 1 on lower side, described lower seal head 8 lower end is provided with suction port 9, described silencer cylinder 1 inside is provided with multiple dividing plate 2, and the opening of dividing plate 2 is not on the same line, it is cotton that described dividing plate 2 inside is filled with sound absorption, described through hole 3 is arranged in triangle or rectangular, described silencer cylinder 1 bottom is provided with base 7 and varies in size.
Specific works process: during use, noise enters silencer cylinder inside from suction port, and the opening of each dividing plate is different, upset the air-flow in silencer cylinder and sound wave, the sound absorption cotton of diaphragm internal also has the effect reducing noise, and last gas is got rid of from through hole, effectively reduces noise.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
