Description
Technical field
The utility model relates to a kind of one-way cock, particularly a kind of one-way cock of controlling gas communication by piston.
Background technique
Along with people are to health problem pay attention to day by day, the ventilation of article of footwear and ventilatory become when being the favorite on market, and article of footwear ventilates and the key of ventilation is widely used as realizing for air bag and one-way cock.One-way cock in the past, mostly is metal and makes, and quality is relatively heavier, and complicated structure, price comparison costliness, be not all suitable for shoe-making field; In recent years, the technical expert of shoemaking and mechanical field has researched and developed the multiple one-way cock for article of footwear or air bag, as utility model patent CN201320182669.8, CN201120436769.X etc., these one-way cock lighter weight, with low cost, but owing to being subject to the restriction of its structure, cause tightness stable not, also be restricted the working life of valve, causes be also affected the working life of article of footwear.
For above-mentioned existing deficiency and demand, the purpose of this utility model is to provide that a kind of quality is light, volume is little, tightness is strong, and working life longer one-way cock.Whether this one-way cock controls gas communication by piston, is applicable to the field of athletic equipment such as footwear, clothes.
Summary of the invention
In order to realize above-mentioned functions, the technical solution adopted in the utility model is:
Piston check valve door, is comprised of air inlet storehouse, Valve plug, piston; Air inlet warehouse is provided with suction port, and valve cock body is provided with air outlet, and Valve plug is connected with air inlet storehouse, and piston is between suction port and air outlet.
The opening-like state of the suction port the other end in described air inlet storehouse, opening end is connected with Valve plug.
The suction port end in described air inlet storehouse is provided with the breathing pipe attachment post in air inlet storehouse, and its breathing pipe is connected with suction port.
The breathing pipe in described air inlet storehouse connects the draw-in groove that cylinder is provided with air inlet storehouse breathing pipe attachment post.
Described Valve plug is comprised of cock body and card, and the internal diameter in the external diameter of cock body and air inlet storehouse matches, and the external diameter in the external diameter of card and air inlet storehouse matches, and cock body end is provided with air outlet, the other salient point that is provided with in air outlet.
Described Valve plug is comprised of the breathing pipe attachment post of cock body, card, Valve plug, the internal diameter in the external diameter of cock body and air inlet storehouse matches, the external diameter in the external diameter of card and air inlet storehouse matches, cock body end is provided with air outlet, the other salient point that is provided with in air outlet, the breathing pipe attachment post of Valve plug is connected in card, and its breathing pipe is connected with air outlet.
The breathing pipe of described Valve plug connects the draw-in groove that cylinder is provided with Valve plug breathing pipe attachment post.
Described piston is comprised of cap and cylinder, and the diameter of cylinder is less than the internal diameter of air outlet, and the external diameter of cap is greater than the internal diameter of suction port and air outlet.
Described cap is divided into cap body part and cap edge part, and the peripheral radian of cap body part and the radian of suction port intrados main body match, and the inner side of cap body part is in line; The peripheral radian of cap edge part is slightly larger than the radian of suction port intrados corresponding thereto, and the thickness of cap edge part is less than the thickness of cap body part, and the thickness of cap edge part is along with the attenuation gradually that reduces of back gauge.
During use, the cylinder of piston is put into the air outlet of Valve plug, the cap frame of piston is on the other salient point in air outlet, and now, piston is not blocked air outlet completely.Then, the valve that is placed with piston is filled in to air inlet storehouse opening end, be connected with air inlet storehouse, piston can move between air outlet and suction port.
The beneficial effects of the utility model are:
When gas flows to air outlet direction from suction port, air-flow promotes piston and moves to air outlet direction, and the cylinder of piston is put into air outlet, and the cap frame of piston is on the other salient point in air outlet.Because the external diameter of piston cylinder is less than the internal diameter of air outlet, the cap of piston by frame on the other salient point in air outlet, so piston cannot be blocked air outlet completely.Now, piston check valve door is opening state, and gas flows out by the gap between piston and Valve plug air outlet.The inner side of the piston cap main body shape that is in line, contacts with the salient point of Valve plug, and further the distance between oversize piston cap and Valve plug, guarantees gas communication.
When gas flows to suction port direction from air outlet, air-flow promotes piston and moves to suction port direction, because the external diameter of piston cap is greater than the internal diameter of suction port, the radian of cap is consistent with the radian of suction port intrados in air inlet warehouse, and piston cap has been blocked suction port completely; Now, piston check valve door is in closed condition, and gas cannot flow out from suction port.The radian of piston cap edge part is slightly larger than the radian of suction port intrados corresponding thereto, the thickness of cap edge part is less than the thickness of cap body part, and the attenuation gradually that reduces along with back gauge, when gas flows to suction port direction from air outlet, under the promotion of air-flow, the piston cap edge part of thinner thickness closely touch corresponding suction port intrados, further prevents the circulation of gas, strengthens the tightness of one-way cock.
Air inlet storehouse, Valve plug all adopt the disposable ejaculation of the good material of toughness to make, piston adopts hardness material soft, that toughness is strong to make, make the utlity model has the features such as volume is little, quality is light, tightness is good, cheap for manufacturing cost, one-way cock structure setting in the form of piston, and the radian of piston cap and the feature of thickness, the stability of strengthening one-way cock performance, is applicable to the field of athletic equipment such as footwear, clothes.
