Abstract
The utility model provides a novel exhaust valve, the piston type unloading valve comprises a valve body and a valve cover, the inside flotation pontoon that is provided with of valve body, the inside gas vent that is provided with of valve gap, one side section that is provided with the gas vent on the valve gap is for domatic, one side that the flotation pontoon top is close to the gas vent is domatic parallel domatic with the valve gap, the flotation pontoon top is provided with sealed diaphragm, the valve body is provided with draw -in groove, this draw -in groove and the terminal swing joint of sealed diaphragm with the inner wall top of gas vent homonymy, the flotation pontoon top be close to be provided with on gas vent one side domatic with the parallel support frame in flotation pontoon bottom surface, the bottom of flotation pontoon is the cylinder, and the top is the domatic cone of half side one -tenth, the intermural guiding mechanism that is provided with in the lateral wall of flotation pontoon and the valve body. The utility model has the beneficial effects of: this equipment structure is simple, can effectively improve discharge pressure and discharge of fumes and gas, and the sealed specific pressure of reinforcing solves that current discharge valve discharge pressure is low, the high pressure produces stifled, the exhaust capacity subalternation problem in the twinkling of an eye of gas.
Description
First, technical field
This utility model is related to a kind of valve, more particularly to a kind of novel vent valve.
2nd, background technology
Air bleeding valve is applied to independent heating system, central heating system, heating boiler, central air-conditioning, floor heating and too
The pipeline air exhaust waters such as sun energy heating system.Because generally all dissolved with certain air in water, and the dissolubility of air is with temperature
Rising and reduce, such water gas during circulation gradually is separated from the water out, and formation of gradually getting together is big
Bubble in addition gas column because there being the supplement of water, often have gas to produce, therefore, the quality of air bleeding valve and efficiency right and wrong
Often important.But present air bleeding valve on the market, mostly have that pressure at expulsion is low, high pressure produce gas block up, moment exhaust capacity
The defect of difference, can effectively improve pressure at expulsion and capacity now on the market, strengthen seal pressure, solve existing air bleeding valve row
The air bleeding valve of the problems such as atmospheric pressure is low, high pressure generation gas blocks up, moment exhaust capacity is poor is not also found, and has to be developed.
3rd, utility model content
In order to overcome the weak point of existing air bleeding valve, this utility model provides a kind of novel vent valve.
The technical solution of the utility model is realized in.
A kind of novel vent valve of this programme, including valve body and valve gap, described valve inner is provided with floating drum, described valve gap
It is internally provided with air vent, the side section that described valve gap is provided with air vent is domatic, and described floating drum top is near aerofluxuss
Mouthful side be domatic with valve gap parallel domatic；Described floating drum top is provided with seal membrane, and described valve body is same with air vent
The inwall top of side is provided with draw-in groove, and this draw-in groove is flexibly connected with seal membrane end；Described floating drum top is near air vent one
Side domatic on be provided with the bracing frame parallel with floating drum bottom surface, described seal membrane is used for sealing air vent.
The bottom of described floating drum is in cylinder, and top is the domatic cone of half side one-tenth.
It is provided with guiding mechanism between the inwall of the side wall of described floating drum and valve body.
Of the present utility model it is beneficial in that：This device structure is simple, can effectively improve pressure at expulsion and capacity,
Strengthen seal pressure, solve the problems such as existing air bleeding valve pressure at expulsion is low, high pressure generation gas blocks up, moment exhaust capacity is poor.
4th, brief description
Fig. 1 is structural representation of the present utility model.
5th, specific embodiment
A kind of novel vent valve as depicted, including valve body 1 and valve gap 2, described valve body 1 is internally provided with floating drum 3, institute
State valve gap 2 and be internally provided with air vent 7, the side section that described valve gap 2 is provided with air vent 7 is domatic, and described floating drum 3 pushes up
Portion is domatic with valve gap 2 parallel domatic near the side of air vent 7；Described floating drum 3 top is provided with seal membrane 4, described
Valve body 1 is provided with draw-in groove 6 with the inwall top of air vent 7 homonymy, and this draw-in groove 6 is flexibly connected with seal membrane 4 end；Described floating
Cylinder 3 tops near air vent 7 side domatic on be provided with the bracing frame 5 parallel with floating drum 3 bottom surface, described seal membrane 4 is used
In sealing air vent 7.
The bottom of described floating drum 3 is in cylinder, and top is the domatic cone of half side one-tenth.
It is provided with guiding mechanism between the inwall of the side wall of described floating drum 3 and valve body 1.
When using this utility model, the domatic and valve gap 2 of floating drum 3 top surface has domatic the matching of air vent 7 side, leads to
Cross this two domatic between seal membrane 4 play the effect of sealing, when exhaust valve operation, liquid level is relatively low, and floating drum 3 is located at
Valve body 1 bottom, drives the domatic separation of seal membrane 4 and valve gap 1, leaves air vent 7, can guarantee that big capacity aerofluxuss, work as liquid
Body enter valve body 1 internal when, when floating drum 3 contact liq floats, seal membrane 4 is progressively fitted the domatic, to greatest extent of valve gap 1
Holding keep aerofluxuss should the row of draining, when liquid level continue rise, the domatic crush seal in the top diaphragm 4 of floating drum 3, because floating drum 3
Under buoyancy, it is domatic that seal membrane 4 can fit tightly valve gap 2 top, thus ensureing that liquid will not flow out from air vent 7,
With ensure low pressure water-stop requirement, the bracing frame 5 at floating drum 3 top in the presence of buoyancy, crush seal diaphragm 4, make sealing
Diaphragm 4 is domatic with valve gap 2 top contact even closer, enhance sealing effectiveness.
Above an embodiment of the present utility model is described in detail, but described content is only of the present utility model
Preferred embodiment is it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., all should still belong within patent covering scope of the present utility model.
