Abstract
The utility model relates to a vertical automatic exhaust valve used for the hot-water heater or waterline non-corrosive liquid to exhaust the inner gas, which is composed of a valve body with a gas inlet, a sealing ring of the valve body, a valve cover, an exhaust outlet, a blocker, a guide bar, a sealing gasket and a floater. The utility model is characterized in that between the exhaust outlet and the guide bar a guide bushing is fixed on the valve cover, a locking ring fixed on the guide bar can make the guide bar clamped in the guide bushing and can only move top and bottom in certain space in the guide bushing, and the floater and the guide bar are hung in the valve body. When in use, the structure has the advantages of good sealing property and high sensibility, and the guide bar can not cause offset.
Description
The utility model belongs to valve class technology, specifically a kind of automatic control pressure vent that is applicable to hot water heating or the non-erosion fluid removal of water-supply line system endosome.
The kind of the outlet valve of non-its internal system gas of erosion fluid removal of water-supply line is more at present, wherein use a kind of vertical automatic exhaust valve is arranged more widely, this outlet valve mainly is made up of valve body, exhaust nozzle, guide rod, float etc., the guide holder that one tape guide pin is arranged at the suction port place of valve body liner bottom, this guide pin inserts in the guide rod bottom centre hole, does not produce skew and play when float and guide rod rising.But in actual applications, because all multifactor influences such as the intensity of the weight of guide rod and float self and guide pin and precision are difficult to make guide rod not produce skew, and make outlet valve ineffective.In addition because the suction port of valve body itself is less, and one guide holder is set again, has reduced air displacement relatively, thereby reduced the sensitivity of outlet valve at the suction port place.
The purpose of this utility model is to provide that guide rod does not produce skew in a kind of exhaust process, highly sensitive vertical automatic exhaust valve.
The purpose of this utility model is achieved in that it includes valve body, valve seals, valve gap, exhaust nozzle, shutoff, guide rod, seal rubber pad and a float of bringing gas port into, it is characterized in that between exhaust nozzle and guide rod, being provided with a guide pin bushing that is fixed on the valve gap, the upper end of guide rod be fixed with one guide rod is stuck in the guide pin bushing and can only the certain interval in guide pin bushing in the collar that moves up and down, guide rod and float are unsettled in valve body.
The utility model is owing to cancelled time guide holder, and it is by the collar of guide rod upper end that the upper end of guide rod is spacing in guide pin bushing, make guide rod in certain interval, to do vertical motion up and down, and the effect of replacement guide holder, therefore increased the bore of suction port relatively, increased the flow of water or gas, improved the sensitivity of outlet valve, and in use guide rod can not produce any skew.Float adopts the compression-molding process manufacturing in addition, has increased weight, has improved working pressure, has overcome the damage of float simultaneously again.
To be further described embodiment of the present utility model by accompanying drawing below.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, concrete structure of the present utility model is: it comprises that one has valve body 1, valve gap 2, the valve seals 12 of suction port, roof anchorage at valve gap 2 has an exhaust nozzle 5, the shutoff 4 of decorating action is together arranged on the exhaust nozzle 5, and exhaust nozzle 5 times links to each other with guide pin bushing 8 by exhaust nozzle rubber cushion 6 and locatees it.Guide pin bushing 8 also is sealed with guide pin bushing rubber cushion 7 with the contacting point of valve gap 2.Guide rod 3 is had an end of seal rubber pad 9 and the collar 10 by this end is stuck in guide pin bushing 8 inner side slots, its seal rubber pad 9 is corresponding with the mouth of exhaust nozzle 5, and the other end of guide rod 3 is spacing a hollow float 11 arranged, after valve body 1, valve seals 12, valve gap 2 were by fastening screw trip bolt 13 sealings, its guide rod 3 that has hollow float 11 was suspended in valve body 1 volume inside.During use, the utility model is installed on the pipeline of required vent systems extreme higher position, the gas that is produced in the system can be emitted by automatic valve at any time.When water enters valve body, hollow float 11 is held up, guide rod 3 rises thereupon, and the seal rubber pad 9 at guide rod 3 tops blocks exhaust nozzle 5 rapidly.When being full of air in the valve body, hollow float 11 is opened exhaust nozzle 5 external exhausts rapidly by from hanging down.
Claims (2)
1, a kind of vertical automatic exhaust valve, it includes valve body, valve seals, valve gap, exhaust nozzle, shutoff, guide rod, seal rubber pad and a float of bringing gas port into, it is characterized in that between exhaust nozzle and guide rod, being provided with a guide pin bushing that is fixed on the valve gap, the upper end of guide rod be fixed with one guide rod is stuck in the guide pin bushing and can only the certain interval in guide pin bushing in the collar that moves up and down, guide rod and float are unsettled in valve body.
2, vertical automatic exhaust valve according to claim 1 is characterized in that having exhaust nozzle rubber cushion and guide pin bushing rubber cushion respectively between exhaust nozzle and guide pin bushing and guide pin bushing and valve gap.
