Description
Technical field
The utility model relates to gas pressure reducer field, is specifically related to one just to lever gas pressure reducer.
Background technology
Gas pressure reducer is a kind of device that high pressure gas carry out reduce pressure with Flow-rate adjustment. The utilization of gas pressure reducer is extensive, uses when the hypertonia in gas cylinder or pipeline is not suitable for work, it is necessary to reduce pressure through pressure reducer, to reach the pressure required for normal use. The function that pressure reducer not only has a decompression also has the effect of voltage stabilizing, when gas cylinder or pipeline rate of discharge change, through the decompression pressure regulation of pressure reducer, can keep stable output pressure.
Gas piping system widely uses gas pressure reducer high pressure air reducing extremely required low pressure, meet the needs of system. From step-down aspect, reducing valve and throttling valve, all there is buck functionality, intake pressure is down to a certain the top hole pressure needed; Though but throttling valve by throttle flap throttling have reduce system pressure effect, but due to its throttle area be constant, therefore its top hole pressure changes with the change of intake pressure, can not be stabilized to a steady state value; The elastic element of reducing valve dependence itself and the energy of medium own so that it is throttling area changes with the change of intake pressure, and its choke pressure drop also changes thereupon, keep top hole pressure substantially constant from face. In brief, the principle of work of reducing valve is throttling, and gas stream, when gap between valve and valve base, produces pressure drop, reaches the object of decompression.
Existing membrane type gas pressure reducer coordinates return spring to realize the adjustment of top hole pressure by the distortion of diaphragm, general employing connects with a parallel push rod between spool valve and regulation component, make the axis being parallel of shunt assembly, push rod, regulation component, this direction size of reducing valve is uncontrollable in shorter scope, structure is compact not, and the equipment practicality installing space crowded at some is not strong.
Practical novel content
In view of this, the purpose of this utility model is to provide one just to lever gas pressure reducer, adopts lever that the motion of regulation component and shunt assembly is connected, makes the structure of whole reducing valve compacter, and reliably.
The technical scheme adopted for realizing the purpose of this utility model is: one is just to lever gas pressure reducer, the shunt assembly comprising valve body and be arranged in valve body and regulation component, it is characterized in that, lever also it is provided with in described valve body, one end and the regulation component of described lever are hinged, being provided with movable power transmission push rod between the other end of described lever and shunt assembly, described push rod is positioned at valve inner, hinged with valve body in the middle part of described lever.
Further, the axis of described shunt assembly and the axes normal of regulation component.
Further, described push rod is slidably arranged on valve body.
Further, the two ends of described push rod are spherical.
Further, described shunt assembly comprises spool valve and spool valve seat, is provided with return spring between described spool valve seat and valve body.
Further, the top of described regulation component is provided with pressure regulation nut, is provided with pressure regulation spring between described regulation component and pressure regulation nut.
Further, described lever is L-type, and described lever and the hinged position of valve body are in the corner of L-type lever.
Further, also comprising relief valve assembly, described relief valve assembly is arranged on the side of valve body, the axis of described relief valve assembly and the axis being parallel of regulation component.
The beneficial effects of the utility model:
The utility model has that structure is simple, pressure-stabilisation, weight light, regulate the advantages such as easy for installation, when gas cylinder or pipe outlet flow change, decompression through pressure reducer regulates, just can keep stable output pressure, during work, the output pressure of the overflow effect of safety valve and the aperture vary stable pressure reducer outlet at diverting valve assembly and spool valve place.
The intersect vertical axis of shunt assembly and regulation component, the vertical movement direction of regulation component is turned into the tangential movement along shunt assembly by the lever of " L " type and push rod by centre, form the control mode of feedback, in the profile of reducing valve, this kind of structure mode makes axial length reduce, and is installing adaptability enhancing on the compact equipment in space.
