Abstract
The utility model discloses an automatic outlet valve, which is provided with a valve body 6, wherein, the lower end of the valve body 6 is provided with an inlet 10, and the upper end of the valve body 6 is provided with an exhaust outlet 2; the inner part of the valve body is provided with a float 7 which is provided with a through hole 11 which is communicated with the inner and the outer sides of the valve body 6; the upper end of the float 7 is connected with an exhaust plug 3 which is matched with the exhaust outlet 2. The utility model has the advantages of higher sensitivity and better exhaust under the action of high temperature air, and long service life.
Description
The utility model has related to a kind of venting gas appliance of pressure system, especially a kind of automatic control pressure vent.
Existing automatic control pressure vent adopts spring control vent plug more, and in the very fast corrosion of the effect lower spring of high-temperature gas, elasticity weakens gradually until forfeiture, from the outlet valve overflowing liquid, and loses the automatic vent function, and the outlet valve life-span is short, and sensitivity is low.
The purpose of this utility model provides and a kind ofly still can keep higher sensitivity and good degassing function under the high-temperature gas effect, and the automatic control pressure vent of long service life.
Technical solution of the present utility model is: a kind of automatic control pressure vent, be provided with valve body 6, import 10 is established in the lower end of valve body 6, exhaust nozzle 2 is established in the upper end, is provided with float 7 in the valve body, float 7 is provided with the through hole 11 inside and outside the connection valve body 6, and float 7 upper ends are connected to the venting plug 3 that matches with exhaust nozzle 2.
The utility model compared with prior art has: still can keep higher sensitivity and good degassing function and the advantage of long service life under the high-temperature gas effect.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Fig. 1 is the utility model embodiment's a structural representation.
As shown in Figure 1, the utility model embodiment's valve body 6 lower ends are provided with import 10, the top scyewed joint of valve body 6 has the valve gap 4 of band boss, valve gap 4 is provided with the hole, the boss place scyewed joint of valve gap 4 has the exhaust nozzle 2 of band boss, the boss place scyewed joint manually operated valve 1 of exhaust nozzle 2, manually operated valve 1 side has exhaust port, the turn manually operated valve is to regulate air displacement, be provided with float 7 in the valve body 6, float 7 is marked with through hole 11 in the middle of being formed by low density polyethylene, float 7 is extension bar 5 in succession, connecting rod 5 welding venting plugs 3, venting plug 3 is a frustoconic shape, major part is provided with step, the step circumference evenly is provided with aperture 9 as exhaust, quantity is optional more than 4, step places on the boss of valve gap 4, aperture 9 is located at the outside in the hole of exhaust nozzle 2, in system, there is gas, float places shown position by own wt, gas is entered by inlet hole 10, through float through hole 11, the hole of valve gap 4, venting plug 3 excircle apertures 9, the hole of outlet nozzle 2, the side opening of manually operated valve 1 is discharged, after the valve water inlet, float 7 is held up, the hole is blocked, be used for stoping water excessive thereby drive the small boss place that moves to exhaust nozzle 2 holes on the venting plug 3, rubber pad 8 all is equipped with in this valve connecting part, and other parts all adopt copper production except that float.
