Description
Technical field
The utility model relates to filter apparatus field, particularly relates to a kind of exhaust gear.
Background technology
Filter is in the market generally that filtering material is made into filter core, puts into stainless steel urceolus and combinationally uses.This kind of filter at beverage, be widely applied in the industries such as electronics, but such filter price general charged is higher, and the replacing inconvenience of filter core, the seal operation of processing filters is very long, the more important thing is more renew cartridge time human body to contact raffinate, have contaminative if raffinate is chemical agent and can produces certain injury to human body, the filter be therefore applied in the middle of chemical agent supply process requires to have good sealing at filter process.
Thereby produce the filter of all kinds of integral types, the filter of integral type is also referred to as bag type filter, and shell adopts polypropylene material usually, generally has three joints to be respectively inlet attack, outlet connection and exhaust joint.Wherein, exhaust outlet generally tightens a screwed exhaust sealing cap sealing.Its using method is when bringing into use bag type filter, is turned on by exhaust cap, starts, from entrance input liquid to be filtered, when waiting liquid to be full of whole bag type filter, then to be tightened by exhaust cap, reach the object of discharging gas in bag type filter with this.There is an obvious defect in the fixed form of this exhaust cap, then unscrews in the process of exhaust cap, when in bag type filter, air pressure is excessive, exhaust cap can be flicked, and easily produce injury to human body, and exhaust cap is very little, easily loses, and impact uses.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of exhaust gear.
The utility model is achieved through the following technical solutions:
A kind of exhaust gear, comprise sealing cap, holder, push rod, described sealing cap is threaded connection and is fixed on holder, described push rod passes and is fixed on holder from sealing cap and holder, the middle part of described push rod is provided with pressing plate, described push rod top is positioned at sealing cap top and is provided with operating portion, the upper surface of described pressing plate is provided with sealing gasket, the bottom of described push rod is provided with press section, the position corresponding with the side of press section, the bottom of described holder is provided with bellmouth, press section side between described press section and bellmouth is provided with the second sealant, described holder inside is provided with wireway, the air inlet of described wireway is arranged on bellmouth hole wall, the gas outlet of described wireway is arranged on the top of holder.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, structure is simple, be threaded connection the connection that realizes structure and pretightning force produces, make the large good sealing effect of the pretightning force between structure, also ensure that when carrying out tightening with the operation of unclamping, adopt tool control operating portion, simple to operate laborsaving, the structure of bellmouth and double-layer sealing structure is adopted to make gas more be difficult to spill, the size of steam vent can be made to increase, when adopting many exhaust passage exhausts, gas discharging efficiency increases, safer during operation, and the structure of integral type is more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-holder; 2-sealing cap; 3-sealing gasket; 4-push rod; 5-pressing plate; 6-wireway; 7-press section; 8-second sealant; 10-bellmouth; 40-operating portion.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of exhaust gear, comprise sealing cap 2, holder 1, push rod 4, described sealing cap 2 is threaded connection and is fixed on holder 1, described push rod 4 passes and is fixed on holder 1 from sealing cap 2 and holder 1, the middle part of described push rod 4 is provided with pressing plate 5, and the diameter of described pressing plate 5 compares the diameter large 1/2 in the hole on sealing cap 2 top corresponding with it.Described push rod 4 top is positioned at sealing cap 2 top and is provided with operating portion 40, and the upper surface of described pressing plate 5 is provided with sealing gasket 3, and the bottom of described push rod 4 is provided with press section 7, and the position that the bottom of described holder 1 is corresponding with the side of press section 7 is provided with bellmouth 10.Rotation process portion 40 makes push rod 4 move up, and makes pressing plate 5 and press section 7 produce pretightning force simultaneously and compresses, good sealing effect.
Press section 7 side between described press section 7 and bellmouth 10 is provided with the second sealant 8, and described holder 1 inside is provided with wireway 6.The air inlet of described wireway 6 is arranged on bellmouth 10 hole wall.The gas outlet of described wireway 6 is arranged on the top of holder 1.During exhaust, rotation process portion 40 makes push rod 4 move down, and pressing plate 5 and press section 7 are unclamped simultaneously, and gas, through wireway 6, is finally discharged from the hole on sealing cap 2 top.The utility model is reasonable in design, structure is simple, be threaded connection the connection that realizes structure and pretightning force produces, make the large good sealing effect of the pretightning force between structure, also ensure that when carrying out tightening with the operation of unclamping, adopt tool control operating portion, simple to operate laborsaving, the structure of bellmouth and double-layer sealing structure is adopted to make gas more be difficult to spill, the size of steam vent can be made to increase, and when adopting many exhaust passage exhausts, gas discharging efficiency increases, safer during operation, and the structure of integral type is more stable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
