Description
Technical field
The utility model relates to a kind of city rail vehicle steam whistle loudspeaker.
Background technique
Two section header cars of city rail vehicle are respectively equipped with a cover steam whistle system, and from the debugging situation at scene, it is too high generally to react the loudspeaker volume, surpasses 110 decibels, surpassed city rail vehicle steam whistle loudspeaker standard, and steam whistle loudspeaker itself does not possess volume adjusting function.In order to reduce the volume of loudspeaker, conventional way is that the pipeline at the loudspeaker suction port adds in order to reduce the thing of cramming of gas flow area.But there is shortcoming in this method: the one, and it is wayward to cram the thing size, and flow area can't be regulated; The 2nd, cause pipeline blockage easily.
Summary of the invention
The purpose of this utility model is, at the deficiencies in the prior art, provides a kind of city rail vehicle steam whistle loudspeaker, but the volume of free adjustment steam whistle loudspeaker, and simple in structure, can not cause pipeline blockage.
The technical solution of the utility model is, a kind of city rail vehicle steam whistle loudspeaker, comprise the pipeline that feeds gas to the loudspeaker suction port, the modulating valve of regulating the loudspeaker volume is installed on the described pipeline, this modulating valve comprises valve body, be provided with the valve body inlet hole that is connected with pipeline and the valve body air outlet hole that is connected with the loudspeaker suction port in the valve body, described valve body inlet hole and valve body air outlet hole are communicated with by attachment hole; The controlling mechanism that the control valve body inlet hole feeds gas flow is installed in the described attachment hole.
The longitudinal center line of described valve body inlet hole and the longitudinal center line of attachment hole are point-blank, and dock with the attachment hole in being deep into valve body is inner the valve body inlet hole the inner that is deep in the valve body, and described valve body air outlet hole is communicated with the attachment hole sidewall of close attachment hole the inner.
Described attachment hole is divided into A hole and B hole successively from the valve body outer end to valve inner, and the diameter in A hole is greater than the diameter in B hole, and is provided with internal thread at A hole inwall.Attachment hole is divided into the different A hole of diameter and B hole, makes screw rod tight with being connected of attachment hole, also make the accurate positioning after screw rod penetrates in the attachment hole simultaneously.
Described controlling mechanism comprises valve rod and the outside nut that is used for fastening valve rod of valve body that penetrates in the attachment hole; But described valve rod comprises stem head, valve rod first linkage section, valve rod second linkage section of shutoff valve body inlet hole in turn and is with externally threaded threaded stem section, described threaded stem section screws in the A hole, and described valve rod first linkage section and valve rod second linkage section all place in the B hole, the section radius of described valve rod second linkage section is less than the section radius of valve rod first linkage section, and the inner, valve body air outlet that is deep in the valve body places a side and valve rod second linkage section of valve rod second linkage section and is deep between the interior the inner, valve body air outlet of valve body gapped.
The described valve rod first linkage section outer wall is provided with annular groove, and O type sealing rubber ring is installed in groove.
The inner of described valve body inlet hole is taper.
Principle of the present utility model and operating process be, valve rod enters in the attachment hole, and stem head blocks shutoff valve body inlet hole fully, and with the nut screwing clamping valve rod, and then the valve body suction port does not have gas and flows into valve body air outlet hole, steam whistle loudspeaker voiceless sound; Unscrew nut, make valve rod mobile gradually to the valve body outside, then the flow area of valve body suction port increases gradually, and the sound of steam whistle loudspeaker also increases gradually; When needs reduce volume, only need fastening nut, valve rod is moved to valve inner.
As known from the above, city rail vehicle steam whistle loudspeaker described in the utility model can effectively be regulated the loudspeaker volume, are well positioned to meet steam whistle loudspeaker volume standard; Volume modulating valve of the present utility model adopts the stainless steel manufacturing to form, and simple and reliable for structure, course of working is simple and easy, and easy installation and removal, cost are cheap relatively; Volume modulating valve of the present utility model adopts the rod seal mode, has fully guaranteed the tightness of valve.The Flow-rate adjustment scheme of control valve port flow area is simple and reliable.
