Abstract
The utility model relates to a cavitation erosion and noise eliminator of a water-ring vacuum pump, belongs to appurtenances of a sterilizer, and is applied to a water-ring vacuum pump of a vacuum-series sterilizer. The cavitation erosion and noise eliminator is provided with a one-way valve body and a valve body adaptor connected mutually; an O-shaped sealing ring is additionally arranged in the contact position of the one-way valve body and the valve body adaptor; a one-way valve rod is arranged between the one-way valve body and the valve body adaptor, an O-shaped sealing ring is arranged between the one-way valve rod and the conical surface of the rear end of the valve body adaptor; a spring is mounted on the one-way valve rod, and corresponds to the rear end of the one-way valve rod; an air inlet passage is arranged on the one-way valve body; the front end of the valve body adaptor is connected with a cavitation erosion protective valve adaptor; and small holes for ventilation are formed on the cavitation erosion protective valve adaptor. The structure is simple and reasonable, the noise pollution of the water-ring vacuum pump can be eliminated, and the physical and the psychological health of workers can be protected.
Description
Technical field
The utility model relates to a kind of Nash hytor cavitation noise cancellation element, belongs to the Sterilizers appurtenances, is applied on the vacuum series Sterilizers Nash hytor.
Background technique
In the using process of Sterilizers intermediate pump, the gentle follicular rupture sound of echo in the pump housing can produce very big noise when tolerance increases, and when opening gas ballasting or during logical atmosphere, noise can obviously increase, and forms noise pollution, influences workman's physical and mental health.
The model utility content
The purpose of this utility model is to provide a kind of Nash hytor cavitation noise cancellation element, the pollution that abates the noise, protection workman's physical and mental health.
Nash hytor cavitation noise cancellation element described in the utility model; interconnective one-way valve valve body and valve body joint are arranged; the contacting point is added with O-ring seals between one-way valve valve body and valve body joint; be provided with the one-way valve valve rod between one-way valve valve body and valve body joint; be provided with O-ring seals between the conical surface of one-way valve valve rod and valve body joint rear end; on the one-way valve valve rod spring is housed; corresponding with the rear end of one-way valve valve rod; on the one-way valve valve body, be provided with gas-entered passageway; the front end of valve body joint connects cavitation erosion Protective valve joint, and cavitation erosion Protective valve joint is provided with breeder tube.
The utility model is installed on the cavitation erosion mouth of Nash hytor, when the one-way valve valve rod stopped up the gas-entered passageway of valve body joint by O-ring seals, that the utility model noise absorber is not installed was the same with Nash hytor; When the one-way valve valve rod opens wide gas-entered passageway; in vacuum pump, advance a spot of air; the breeder tube restriction full admission amount of cavitation erosion Protective valve joint; make vacuum pump under the situation that does not influence degree of vacuum and maximum rate of air sucked in required; avoid the vacuum pump pressure that reaches capacity, thereby avoid vacuum pump under ultimate pressure, to produce on-mechanical motion noise.
Another effect of one-way valve is to prevent that vacuum pump from spraying water outward by the breeder tube of the Protective valve joint that cavitates, and is safe and reliable.The utility model noise absorber also has the check function that common silencer does not have.
The utility model Nash hytor cavitation noise cancellation element is simple and reasonable, can eliminate the noise pollution of Nash hytor, protection workman's physical and mental health.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
Among the figure: 1, valve body joint 2,3, O-ring seals 4, one-way valve valve rod 5, spring 6, one-way valve valve body 7, cavitation erosion Protective valve joint.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure; Nash hytor cavitation noise cancellation element described in the utility model; interconnective one-way valve valve body 6 and valve body joint 1 are arranged; 1 contacting point of one-way valve valve body 6 and valve body joint is added with O-ring seals 2; 1 of one-way valve valve body 6 and valve body joint are provided with one-way valve valve rod 4; be provided with O-ring seals 3 between the conical surface of one-way valve valve rod 4 and valve body joint 1 rear end; spring 5 is housed on the one-way valve valve rod 4; corresponding with the rear end of one-way valve valve rod 4; on one-way valve valve body 6, be provided with gas-entered passageway; the front end of valve body joint 1 connects cavitation erosion Protective valve joint 7, and cavitation erosion Protective valve joint 7 is provided with breeder tube.
During use, the utility model is installed on the cavitation erosion mouth of Nash hytor, when one-way valve valve rod 4 stopped up the gas-entered passageway of valve body joints 1 by O-ring seals 3, that the utility model noise absorber is not installed was the same with Nash hytor; When one-way valve valve rod 4 opens wide gas-entered passageway; in vacuum pump, advance a spot of air; the breeder tube restriction full admission amount of cavitation erosion Protective valve joint 7; make vacuum pump under the situation that does not influence degree of vacuum and maximum rate of air sucked in required; avoid the vacuum pump pressure that reaches capacity, thereby avoid vacuum pump under ultimate pressure, to produce on-mechanical motion noise.
