Abstract
The utility model discloses a quick opening exhaust valve, comprising a valve body; a lower valve port is communicated to the bottom of the valve body; a side valve port is communicated in one side of the valve body; the inner wall of the top of the lower valve port is molded to form an inverted conical port; an elastic rubber film is arranged above the part, higher than the side valve port, of the inner wall of the valve body; a float is fixed at the center of the elastic rubber film; the lower end of the float is sealed in the top of the lower valve port; a valve rod is connected to the top end of the float; the top end of the valve extends from the top of the valve body and is connected with a pressure plate; a pair of hollow guide pipes are vertically connected to the top surface of the elastic rubber film; the top ends of the two hollow guide pipes are respectively connected to the bottom of the pressure plate, multiple through holes are formed in the pipe wall of the hollow pipe from top to bottom. The quick opening exhaust valve is simple in structure, the starting and working of the exhaust valve can be fast realized, and the performances of the exhaust valve are improved.
Description
Technical field
The utility model relates to outlet valve field, is specially a kind of quick open type outlet valve.
Background technique
Outlet valve is widely used in, in gas path pipe transmission, for gas circuit gas is discharged, gas in gas circuit being played to regulating action.Prior art exhaust structure is simple, and exhaust valve opening speed is slow, cannot meet the requirement that in gas circuit, gas is discharged fast.
Model utility content
The purpose of this utility model is to provide a kind of quick open type outlet valve, to solve the slow-footed problem of prior art exhaust valve opening.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of quick open type outlet valve, include valve body, valve body bottom is communicated with lower valve port, valve body one side is communicated with side valve mouth, described lower valve port top is stretched in valve body, and lower valve port top inner wall is shaped to inverted cone mouth, it is characterized in that: the rubber elastic membrane that is positioned at side valve open height top on valve interior wall and is provided with vertical partition valve body, elastic caoutchouc center membrane is fixed with float, described float lower end is shaped to the inverted cone of lower valve port top inner wall form fit, and float lower end is sealed in lower valve port top, described float top is connected with valve rod, described valve stem tip is stretched out from valve body top and is connected with pressing plate, described rubber elastic membrane end face is also vertically connected with a pair of hollow conduit, two hollow conduit tops pass respectively valve body and are connected to pressing plate bottom, on the hollow conduit tube wall of below, valve body top, have from top to bottom respectively multiple through holes.
Described a kind of quick open type outlet valve, is characterized in that: described lower valve port top inner wall is provided with the seal ring of form fit.
In the utility model, gas enters in valve body from lower valve port, float exposes lower valve port top at gas effect float downward, in gas enters valve body time, rubber elastic membrane is upwards deformation under gas pressure intensity effect, thereby auxiliary float fast rise realizes the conducting to valve body, gas is finally discharged from valve body side valve mouth, rubber elastic membrane is upwards when deformation, the through hole on hollow conduit tube wall top exposes in valve body, air is entered in the valve body of rubber elastic membrane top, and then can in valve body, form air pressure balance, stop the deformation of rubber elastic membrane.The utility model is simple in structure, can realize fast exhaust valve opening work, has improved the performance of outlet valve.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
