Description

Y-piece ball type one-way control valve

Technical field this utility model relates to a kind of pipeline one-way control valve, specifically a kind of Y-piece ball type one-way control valve.

Background technology is present, and the hyperbaric oxygen chamber of China more than 95 percent all uses oxygen sucking and discharging device.Between the suction of this device, oxygen discharging tube and the breathing mask, all be to be connected by Y-piece.For make Y-piece to exhale, inhale two passages spaced-apart, reduce " respiration dead space " of oxygen absorption mask, in the suction of Y-piece, deoxygenation passage, diaphragm type gas unidirectional flow valve (being called for short the diaphragm type control valve) is housed respectively.Diaphragm type control valve (see figure 2) in the existing Y-piece, its diaphragm is generally " drawing pin " shape, and the medium pore the nail end of " drawing pin " insertion cylindrical base cross covers on the plane of cylindrical base cross the medicated cap of " drawing pin ".The shortcoming that this diaphragm type control valve exists is: 1. when suction, deoxygenation, air-flow can not make the diaphragm periphery open fully, and opposite side is rolled simultaneously, and the valid circulation area of gas in the suction oxygen passage is reduced.2. for reducing respiratory resistance, no matter the diaphragm of diaphragm type control valve is the rubber material, or plastic material, that all does is very thin.Because of secular Oxidation and the frequent immersion of disinfectant solution, diaphragm easy deformation, hardening, elasticity weaken, respiratory resistance is increased, the sealing property variation causes and exhales, during inhaling of oxygen, inhales, the gas in the deoxygenation passage can not well isolate, cross one another and obscure, be equivalent to increase " respiration dead space ", reduced the concentration of inhaling of oxygen, influence the effect of oxygen uptake and treatment.3. different with season with the region, in suction oxygen process, can produce the globule between diaphragm type one-way valve and diaphragm support, after the globule drying, diaphragm and support stick together easily.In addition, the cylinder-shaped bracket of diaphragm type one-way valve, or cooperate not tight with the Y-piece wall because of the diameter of product own, or because of the permanent aging back diameter that uses diminishes, diaphragm all can be placed its " in box " with the garden cylindrical stent and slide in Y-piece, when diaphragm touches the top of box, diaphragm or open very little, or, suction oxygen resistance is increased, even suction oxygen passage can be sealed by dieback.

The summary of the invention the purpose of this utility model is to provide the one-way control valve of the ball formula in a kind of Y-piece, it has overcome the shortcoming of diaphragm type one-way valve, can make suction, deoxygenation pipeline separately strict, reduces to inhale, the resistance of deoxygenation, improve the concentration of inhaling of oxygen, improve the therapeutic effect of hyperbaric oxygen.

For achieving the above object, the technical scheme that this utility model is taked is: the ball formula one-way control valve in a kind of Y-piece, it is characterized in that in the oxygen uptake passage of Y-piece, the trumpet type cylinder that one baffle plate, a lightweight ball and end at a gulp make progress is housed from top to bottom successively, and the lightweight ball is placed on realizing in the movable cavity of open and close for it of forming between baffle plate and trumpet type cylinder; In the deoxygenation passage of Y-piece, the downward trumpet type cylinder of end at a gulp, a lightweight ball and a baffle plate are housed from top to bottom successively, the lightweight ball is placed on supplying in its movable cavity of realizing closing, opening of forming between trumpet type cylinder and baffle plate.

For ease of dismounting, change sterilization, the junction of above-mentioned Y-piece and oxygen uptake passage, deoxygenation passage is designed to adaptive mutually concavo-convex step-like, and adopts the engage thread connection.

The ball formula one-way control valve that this utility model provides, simple in structure, scientific and reasonable, dependable performance, suction oxygen resistance is little, can improve therapeutic effect, can both use on the oxygen sucking and discharging device of all use Y-pieces, has favorable social and economic benefits.Tried out three months in the Y-piece of GYYC-16 type hyperbaric oxygen chamber oxygen sucking and discharging device through producing in state-run Jiujiang marine machinery plant.Treatment pressure is 0.22Mpa, adopt 30 ' * therapeutic scheme of 2+10min, oxygen supply pressure 0.5Mpa breathes 18 ± 2 times/min., with the examination of U type pipe pressure instrumentation, respiratory resistance≤the 30Pa of ball-type one-way control valve, diaphragm type control valve≤50Pa has obviously reduced respiratory resistance, and the patient thinks that suction oxygen is smooth and easy, be easy to safeguard that the dismounting and change sterilization is convenient.Distortion does not appear in material therefor, and the phenomenon of adhesion does not appear in ball and cone tube wall yet.

Description of drawings Fig. 1 is the structural representation of ball formula one-way control valve embodiment.

Fig. 2 is the structural representation of conventional film chip control valve.

The specific embodiment as shown in Figure 1, among the Y-piece ball type one-way control valve embodiment that this utility model provides, the ball formula one-way control valve in this Y-piece is made up of Y type suction oxygen discharging tube 1, oxygen uptake passage 2, deoxygenation passage 3, lightweight ball 4, trumpet type cylinder 5, circular edges cross baffle plate 6.Arrow is represented the flow direction of gas respectively among the figure.Wherein: in the oxygen uptake passage 2 of Y-piece, the trumpet type cylinder 5 that one circular edges cross baffle plate 6, a lightweight ball 4 and end at a gulp make progress is housed from top to bottom successively, and lightweight ball 4 is placed on realizing in the movable cavity of open and close for it of forming between circular edges cross baffle plate 6 and the trumpet type cylinder 5; In the deoxygenation passage 3 of Y-piece, the downward trumpet type cylinder of end at a gulp 5, a lightweight ball 4 and a circular edges cross baffle plate 6 are housed from top to bottom successively, and lightweight ball 4 is placed in movable cavitys that supply its realization pass, open of 6 formation between trumpet type cylinder 5 and baffle plate.For ease of dismounting, change sterilization, the junction of above-mentioned Y-piece and oxygen uptake passage 2, deoxygenation passage 3 is designed to adaptive mutually concavo-convex step-like, and adopts the engage thread connection.

During use, the Y type is inhaled oxygen discharging tube 1 place and is connected the suction oxygen mask, and the oxygen uptake passage 2 of Y-piece, deoxygenation passage 3 are connected with suction, deoxygenation corrugated tube respectively.During oxygen uptake, oxygen flows into along the direction of arrow in the oxygen uptake passage 2 of Y-piece, and light material ball 4 is with mobile gas, and the big opening end motion to trumpet type cylinder 5 rests on circular edges cross 6 places, and oxygen uptake passage 2 is fully opened.Meanwhile, in the deoxygenation passage 3 of Y-piece, light material ball 4 is with mobile gas, to the osculum end motion of trumpet type cylinder 5, close deoxygenation passage 3 after, rest on the osculum end.During expiration, the direction of motion of the light material ball 4 in the suction oxygen pipeline 2,3 of Y-piece during with oxygen uptake is just in time opposite with effect, and this moment, the oxygen uptake passage 2 of Y-piece was closed, and the deoxygenation passage 3 of Y-piece is opened.
