Utility model content
The purpose of this utility model is to provide a kind of medical gas valve of stopping.
For realizing above-mentioned utility model object, a kind of medical gas of the present utility model valve of stopping, it comprises:
Valve body, described valve body has internal chamber, one side of described valve body is provided with inlet suction port and the air outlet adapter being connected with described internal chamber, in described internal chamber, be provided with spool, gas circuit described in described spool selective exclusion between air outlet adapter and described internal chamber, a side of described spool is also provided with and can applies to described spool the pressing piece of active force.
As further improvement of the utility model, described spool is arranged on the slide bar that is arranged in internal chamber, and can slide along described slide bar.
As further improvement of the utility model, one end of described slide bar is provided with one and stops buffer part.
As further improvement of the utility model, described pressing piece comprises button and push rod.
As further improvement of the utility model, the hassock sheet that is also provided with shim liner on the valve body of described pressing piece side and is oppositely arranged with described shim liner, is also provided with the pressure cap that is fastened on valve body one end between described hassock sheet and button.
Compared with prior art, the beneficial effects of the utility model are: the medical gas of the present utility model valve of stopping can effectively be controlled the emission behaviour of air-flow, it can be grasped flexibly to the use amount of air-flow and service time, and then efficiency and the effect of raising clinical treatment, alleviate the misery of patient in therapeutic process.
Accompanying drawing explanation
Fig. 1 is the stop plan cross-section schematic diagram of a specific embodiment of valve of medical gas of the present utility model.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings, this utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skills are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
As shown in Figure 1, medical gas of the present utility model is stopped valve for using the medical apparatus and instruments of air-flow, especially can be used in the medical apparatus and instruments of oral cavity class, and it can control discharge and the capacity of air-flow.The above-mentioned medical gas valve 100 of stopping comprises valve body 10, and it forms the outward appearance that gas is stopped valve 100, and it has internal chamber 101, and this internal chamber 101 can be used for air feed stream and passes through.Simultaneously, one side of above-mentioned valve body 10 is also provided with inlet suction port 20 and the air outlet adapter 30 being connected with above-mentioned internal chamber 101, above-mentioned inlet suction port 20 be arranged in parallel with air outlet adapter 30, the air-flow with certain speed that enters internal chamber 101 from inlet suction port 20 can spray from air outlet adapter 30, thus the gas circuit of inlet suction port 20, air outlet adapter 30, internal chamber 101 formation airflow.
In above-mentioned internal chamber 101, be also provided with spool 40, this spool 40 is optionally blocked above-mentioned gas circuit, thereby controls the discharge of air-flow and the use amount of air-flow.Particularly, above-mentioned spool 40 is arranged on the slide bar 41 that is arranged in internal chamber 101, and this spool 40 can slide along this slide bar 41, when spool 40 slides into the connector place of above-mentioned air outlet adapter 30 and internal chamber 101, can seal this connector, thereby realize the blocking-up to above-mentioned gas circuit.In addition, one end of above-mentioned slide bar 41 is provided with buffer stop portion 50, when spool 40 slides into above-mentioned buffer stop portion 50 positions, buffer stop portion 50 can stop the further motion of spool 40, thereby play spacing effect, meanwhile, above-mentioned buffer stop portion 50 also comprises the 0 type circle 51 that plays cushioning effect.
In order to control the slip of above-mentioned spool 40, one side of above-mentioned spool 40 is also provided with and can applies to spool 40 pressing piece 60 of active force, this pressing piece 60 comprises button 601 and push rod 602, and above-mentioned button 501 is arranged at one end of push rod 602, and the other end of push rod 602 and spool 40 lean.Thereby when pressing button 601, push rod 602 can apply an active force to spool 40.
In addition, the hassock sheet 80 that is also provided with shim liner 70 on the valve body 10 of above-mentioned pressing piece 60 sides and is oppositely arranged with described shim liner 70, is also provided with the pressure cap 90 that is fastened on valve body 10 one end between described hassock sheet 80 and button 601.
The medical gas of the present utility model valve of stopping can effectively be controlled the emission behaviour of air-flow, and it can be grasped flexibly to the use amount of air-flow and service time, and then improves efficiency and the effect of clinical treatment, alleviates the misery of patient in therapeutic process.
To those skilled in the art, obviously this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or basic feature, can realize this utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in this utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
