Description
Technical field
The utility model relates to a kind of valve body, is specifically related to a kind of vacuum breaker valve.
Background technique
Existing vacuum breaker valve is the check valve body of band spring, easily produce siphonage, and the sealing of valve body can not meet valve body functional requirement sometimes when valve body works.If ensure that valve body can work effectively, just necessary cracking pressure, the sealing of guarantee valve body, makes valve body service behaviour be met.The existence of this phenomenon, makes system rate of fault in the course of the work rise.In order to avoid valve body produces siphonage at work, we improve the structure of valve body, devise a kind of novel valve body, solve the generation of siphonage.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum breaker valve, to solve the above-mentioned multinomial defect caused in prior art.
A kind of vacuum breaker valve, comprise tack baffler, exhaust plug, serum cap and interior nipple, described tack baffler is threaded with exhaust plug, one of them end face of described exhaust plug is provided with cylinder shape groove, exhaust plug is threaded with interior nipple, a cavity is formed between exhaust plug and interior nipple, exhaust plug is located in cavity, the center of cylinder shape groove is provided with a columniform chute, cylinder shape groove is also provided with some through holes running through exhaust plug, described through hole with the axle center of cylinder shape groove for symmetry axis is circumferential array.
Preferably, described serum cap comprises sliding bar and discoid plug, and one end of sliding bar is fixedly connected with plug, and sliding bar is slidably connected in described chute, and described plug is specifically made up of rubber material.
Preferably, described sliding bar is specifically made up of stainless steel material.
Preferably, the degree of depth of described chute is greater than the thickness of plug, and the diameter of described plug 0.2-0.4mm less of the diameter of cylinder shape groove.
Preferably, described sliding bar is specially hollow tubular.
The utility model has the advantage of: the utility model good seal performance, the generation of siphonage can be avoided, do not need cracking pressure that the service behaviour of valve body just can be made to be met, ensure that the effect of valve body in said system, greatly reduce the rate of fault of system.
Accompanying drawing explanation
Fig. 1 is the erection drawing of a kind of vacuum breaker valve described in the utility model.
Fig. 2 is the assembling exploded view of a kind of vacuum breaker valve described in the utility model.

Wherein: 1-tack baffler, 2-exhaust plug, 3-serum cap, 31-sliding bar, 32-plug, 4-interior nipple, 5-cylinder shape groove, 6-chute, 7-through hole.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of vacuum breaker valve, comprise tack baffler 1, exhaust plug 2, serum cap 3 and interior nipple 4, described tack baffler 1 is threaded with exhaust plug 2, one of them end face of described exhaust plug 2 is provided with cylinder shape groove 5, exhaust plug 2 is threaded with interior nipple 4, a cavity is formed between exhaust plug 2 and interior nipple 4, exhaust plug 2 is located in cavity, the center of cylinder shape groove 5 is provided with a columniform chute 6, cylinder shape groove 5 is also provided with some through holes 7 running through exhaust plug 2, described through hole 7 with the axle center of cylinder shape groove 5 for symmetry axis is circumferential array.
It should be noted that described serum cap 3 comprises sliding bar 31 and discoid plug 32, one end of sliding bar 31 is fixedly connected with plug 32, and sliding bar 31 is slidably connected in described chute 6, and described plug 32 is specifically made up of rubber material.
In the present embodiment, described sliding bar 31 is specifically made up of stainless steel material, and wear resistance and good corrosion resistance are not fragile.
In the present embodiment, the degree of depth of described chute 6 is greater than the thickness of plug 32, and the diameter of described plug 32 0.2-0.4mm less of the diameter of cylinder shape groove 5, be convenient to plug 32 and slide in cavity, play the effect eliminating negative pressure in container.
In addition, described sliding bar 31 is specially hollow tubular, reduces the weight of sliding bar 31, is convenient to gas and pushes plug 32 open.
Working principle of the present utility model is: after installing vacuum breaker valve additional, gas will enter into airtight water container from tack baffler 1, eliminate the negative pressure produced from flow-off, thus realize eliminating this phenomenon of siphon, gas is arrange the body that holds one's breath from interior nipple 4 enters vacuum breaker valve time, because exhaust plug 5 to kill thus be not outwards vented by serum cap 5, otherwise gas can enter through exhaust plug 2 and enters into airtight water container through interior nipple 4 when gas enters from tack baffler 1.
Based on above-mentioned, the utility model good seal performance, can avoid the generation of siphonage, does not need cracking pressure that the service behaviour of valve body just can be made to be met, ensure that the effect of valve body in said system, greatly reduce the rate of fault of system.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
