Abstract
The utility model discloses a silencer used for a relief valve and a compressor comprising same. The silencer comprises a gas accommodating part, and an exhaust part. The air capacitor part is provided with an intake end connected with the relief valve; the surface of the exhaust part is provided with vent holes and is connected with the gas accommodating part. The silencer used for the relief valve is used for muffling an exhaust gas flow of the relief valve; meanwhile, overpressure residual gas released by the relief valve is used for implementing air cooling on a gas cooling and dewatering part of the compressor; the problem of noise generated during the exhausting of the relief valve is solved; and the gas cooling and dewatering part of the compressor is also cooled.
Description
Technical field
The utility model is specifically related to a kind of silencer and a kind of compressor that comprises this silencer of the noise that produces when being used to eliminate the exhaust of compressor safety valve.
Background technique
Medical compressor applies to ICU medical places such as (Intensive Care Unit) usually as the power gas source of equipment such as respiratory machine, and this place is high to the noise index request of compressor, generally below 55dBA.Compressor pump is as the core component of compressor, its life-span has determined the life-span of compressor complete machine, therefore in the design of compressor, for limit compression pump load, the gas circuit element that prevents compressor inside simultaneously is subjected to high pressure and damages, and the adjustable safety valve generally is set in the air-channel system of compressor the pressure maximum of compressor pump output is limited.Yet the airflow noise of safety valve exhaust when work is very big, makes the noise index of compressor complete machine be difficult to satisfy the medical environment usage requirement.
In addition, compressor in the course of the work, during the compressor pump motion, motor can produce a large amount of heats, piston and cylinder bucket rub up and down and also can produce a large amount of heat energy, and these heat energy are diffused into compressor inside by the compressor pump installation room, and the element that is used for cooled gas and divided gas flow moisture in the compressor is heated, cause the gas of compressor output to contain moisture, can not satisfy the particularly requirement of respiratory machine source of the gas of medical source of the gas.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of silencer of the noise that produces when reducing the safety valve exhaust and comprises its compressor.
For solving the problems of the technologies described above, according to an aspect of the present utility model, provide a kind of silencer that is used for safety valve, comprising: air-capacitor portion has the inlet end that is connected with safety valve; Exhaust portion, the surface is provided with exhaust port, and is connected with air-capacitor portion.
Further, silencer also comprises the sound-proof and ventilating material layer, is arranged on the outer surface of exhaust portion and covers exhaust port.
Further, the exhaust port on exhaust portion surface is distributed in a side of exhaust portion.
Further, the exhaust port on exhaust portion surface is distributed on the perisporium of exhaust portion.
Further, soundproof material is a Sound-proof material.
According to another aspect of the present utility model, a kind of compressor is provided, the cooling de-watering portion that comprise compressor pump, is connected with compressor pump and be connected compressor pump and cooling de-watering portion between safety valve, the outlet end of safety valve is equipped with above-mentioned silencer.
Further, be arranged on the silencer exhaust portion lip-deep to the small part exhaust port towards cooling de-watering portion.
Further, also be provided with radiator on the connecting pipeline between compressor pump and the cooling de-watering portion, safety valve is connected between radiator and the cooling de-watering portion by pipeline.
Further, the intended distance that between exhaust port and the cooling de-watering portion there is distance.
Use the silencer that is used for safety valve of the present utility model, the safety valve exhaust airstream is carried out noise reduction, utilize overvoltage residual gas that safety valve discharges to carry out air-cooled simultaneously to the gas cooling portion of dewatering of compressor, the noise problem that had produced when both having solved the safety valve exhaust also lowers the temperature for the gas cooling portion of dewatering of compressor.Use compressor of the present utility model, because above-mentioned silencer is installed, so it is little to have a noise, the advantage that the delivery air moisture content is few.
Description of drawings
Figure of description is used to provide further understanding of the present utility model, constitutes a part of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, does not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 shows the silencer structural representation that is used for safety valve of the utility model specific embodiment; And
Fig. 2 shows the structure compressor schematic representation of the utility model specific embodiment.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The silencer A that is used for safety valve as shown in Figure 1 comprises the air-capacitor portion 1 and the exhaust portion 2 that link together, and wherein air-capacitor portion 1 is provided with the inlet end that is connected with safety valve, and the surface of exhaust portion 2 is provided with the exhaust port that distributes along perisporium.Air-capacitor portion 1 has the effect of the air-flow velocity of baffle safety valve discharge, therefore has erasure effect.On the outer surface of exhaust portion 2, be coated with the sound-proof and ventilating material layer 3 that Sound-proof material is made, the noise that produces when further eliminating the safety valve exhaust.
Compressor as shown in Figure 2, compressor pump D is connected by pipeline with radiator E, radiator E is connected by pipeline with the B of cooling de-watering portion simultaneously, on the connecting pipeline of radiator E and the B of cooling de-watering portion, be provided with safety valve C, the gas outlet end of safety valve C is connected with silencer A as shown in Figure 1, the exhaust port part of its exhaust portion 2 is towards the B of cooling de-watering portion, and interval intended distance between exhaust port and the cooling de-watering portion.In compressor operation, pressurized air comes out from compressor pump D, through radiator E heat radiation, after safety valve C pressure limiting, enters the B of cooling de-watering system.Release the pneumatic noise that gas produces during safety valve C pressure limiting and masked by silencer A, the gas that the exhaust portion 2 of silencer A is discharged directly blows the inner cooling de-watering B of system of compressor, plays cooling-down effect, and that has guaranteed compressor removes outlet capacity and noise index.
The exhaust port of silencer exhaust portion can be located at a side of exhaust portion in other embodiments of the present utility model.
The beneficial effects of the utility model are that effective silencer cheaply applies to compressor, solve compressor because this part noise problem that the safety valve exhaust brings, simultaneously with the disappointing second use of safety valve, reduce the temperature of machine intimate critical component, guarantee the quality of compressor output gas.
