Description
Technical field
The utility model relates to Pressure Control Technology field, especially relates to a kind of venting gas appliance with no pressure.
Background technique
In many production processes, constant pressure or certain degree of vacuum is kept to be often normal necessary conditions of producing.A lot of chemical reaction needs to carry out at constant pressure, for keeping the constant constant pressure also often needing to control principal pressure source of flow.According to different application occasion, Stress control can be in different ways.When control performance is less demanding, fairly simple control gear can be adopted, as pressure regulator valve etc.To performance requirement, higher or production process more complicated, should adopt control pressurer system.The structure of control pressurer system is closed loop, is made up of pressure transducer, pressure controller and controlled device.
Traditional Stress control is more complicated, is not suitable for the Stress control of the container producing flue dust.
Model utility content
The technical problems to be solved in the utility model is: more complicated in order to overcome Stress control traditional in prior art, is not suitable for the pressure controlled problem of the container producing flue dust, provides a kind of venting gas appliance with no pressure.
The utility model solves the technological scheme that its technical problem adopts: a kind of venting gas appliance with no pressure, comprise filter, filter plate, support, exhaust valve cone, balancing weight and outer cover, described shield base has gas mixture inlet, described outer cover inner bottom surface is provided with filtering box, the top of described filtering box arranges filter, described filter plate is fixedly mounted on above filter by support, described filter plate has some first through holes, the upper surface of described support has the second through hole, the top of described support is installed with guide holder, described exhaust valve cone is slidably mounted in guide holder, the top fixed installation balancing weight of described exhaust valve cone, the lower end of described exhaust valve cone is inserted in described second through hole, the side of described support is provided with the air venting mouth be in communication with the outside, described air venting mouth is communicated with described second through hole.
In order to make balancing weight not offset, the inwall of described balancing weight and outer cover is slidably connected.
Gaseous mixture enters filtering box by gas mixture inlet, box enters after filtering and has been in filter after filtration, filter plate is entered after being filtered, because the weight of balancing weight sets in advance, after air pressure reaches more than 0.1Mpa, gas can by exhaust valve cone and balancing weight upwards jack-up, and gas is just discharged by air venting mouth, and the air pressure in outer cover is controlled all the time at below 0.1Mpa.
The beneficial effects of the utility model are: the utility model structure is simple, control the pressure in container, effectively make the air pressure in container control all the time at below 0.1Mpa with the balancing weight of the certain mass set in advance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is two-dimensional representation of the present utility model.
In figure: 1. filter, 2. filter plate, 3. support, be 4. vented valve cone, 5. balancing weight, 6. outer cover, 7. entrance, 8. filtering box, 9. the second through hole, 10. guide holder, 11. air venting mouths.
Embodiment
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The venting gas appliance with no pressure of one as shown in Figure 1, comprise filter 1, filter plate 2, support 3, exhaust valve cone 4, balancing weight 5 and outer cover 6, gas mixture inlet 7 is had bottom outer cover 6, outer cover 6 inner bottom surface is provided with filtering box 8, the top of filtering box 8 arranges filter 1, filter plate 2 is fixedly mounted on above filter 1 by support 3, filter plate 2 has some first through holes, the upper surface of support 3 has the second through hole 9, the top of support 3 is installed with guide holder 10, exhaust valve cone 4 is slidably mounted in guide holder 10, the top fixed installation balancing weight 5 of exhaust valve cone 4, the lower end of described exhaust valve cone 4 is inserted in described second through hole 9, the side of support 3 is provided with the air venting mouth 11 be in communication with the outside, described air venting mouth 11 is communicated with described second through hole 9.
In order to make balancing weight 5 not offset, balancing weight 5 is slidably connected with the inwall of outer cover 6.
Gaseous mixture enters filtering box 8 by gas mixture inlet 7, box 8 enters after filtering and has been in filter 1 after filtration, filter plate 2 is entered after filter 1 filters, because the weight of balancing weight 5 sets in advance, after air pressure reaches more than 0.1Mpa, gas can by exhaust valve cone 4 and balancing weight 5 upwards jack-up, and gas is just discharged by air venting mouth 11, and the air pressure in outer cover 6 is controlled all the time at below 0.1Mpa.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
