Abstract
The utility model relates to an automatic air exhaust valve of a hot water heating system. The utility model is characterized in that the bottom and both the sides of a valve body are provided with water inlet pipes; the interior of the water inlet pipe is provided with a filter screen; the interior of the valve body is provided with a bell float; the lower end of the bell float is provided with three legs, and the upper end of the bell float is provided with a valve sleeve and a valve seat; a guide rod is vertically fixed at the center of the valve seat, and the other end of the guide rod is inserted into a valve nozzle; the bell float freely lifts along the guide rod; the exterior of a pipe cap is provided with a valve cap, which prevents the water from spraying to pollute the ceiling and the wall. The utility model has small volume, simple structure, low cost, vertical and horizontal two purposes, convenient installation and reliable operation. Compared with the existing vertical automatic air exhaust valve, the utility model saves the investment by 50%.
Description
A kind of automatic control pressure vent that relates to hot water system is mounted in the venting gas appliance on the hot water system, is applicable to dwelling house, office building and the installation of public building hot water system.
The hot water system automatic control pressure vent have vertical and horizontal two kinds, but structural principle is mostly identical at present.As Yingkou vertical automatic exhaust valve, to form by valve body, ball float, valve seat, valve nozzle, connecting rod and connecting rod rest, ball float is by the hydraulic pressure lifting, by the connecting rod guiding, by valve seat and valve nozzle sealing.This valve arrangement complexity, directionality is poor, frictional force is big, and lifting is dumb, and is easy to failure, often causes to leak, spray water, and pollutes ceiling or metope.
The purpose of this utility model provides a kind of upright, for sleeping in dual-purpose, simple in structure, and lifting is flexible, does not have the spray water leakage phenomenon, can not pollute the hot water system automatic control pressure vent of ceiling or metope.
The utility model is achieved in that
In the valve inleting water pipe, set up the copper filter screen, in the valve body, three leg bell floats are arranged, the center is provided with valve seat, valve pocket above the bell float, guide rod one end just is vertically fixed on the valve seat center, and the other end inserts in the valve nozzle opening, and valve nozzle leans on rubber ring seal, is fixed on the valve gap center by nut, suitable for reading at valve nozzle, be provided with rubber sheet gasket and pipe cap, there is bonnet the pipe cap outside, is placed on the valve gap.
This automatic control pressure vent is compared with existing automatic control pressure vent, has set up filter screen and stainless steel guide rod, makes the bell float lifting flexibly, accurately, and it is unimpeded to open energy, closes to seal, and has set up bonnet outside pipe cap again, has thoroughly solved water spray and has polluted ceiling and metope problem.This valve horizontal-vertical double-purpose is simple in structure, and volume is little, and is cheap, reduces investment outlay 50% than Yingkou vertical automatic exhaust valve.
Be described further below in conjunction with accompanying drawing:
Fig. 1 automatic control pressure vent structural representation (opening state).
Among the figure: valve body (1), valve gap (8) are made for metal or plastics, and valve body (1) is cylindrical, and respectively there is an intake pipe its bottom centre and both sides, bottom, and copper filter screen (2) is arranged in the pipe.Suitable for reading have a valve gap (8), the flange of valve body (1) and valve gap (8) have at least six bolts to fix, and packing ring (9) just between flange and valve gap, has bell float (3) in the valve pocket, the employing plastics are made, three legs are arranged at the bottom, and bell float (3) is a flat-top, and there are valve pocket (4) and rubber valve seat (5) in the center above the top, valve seat (5) central vertical is inserted a solid stainless steel guide rod (6), the other end inserts in copper valve nozzle (12) hole, and its length is not less than 6mm, cooperates with interporal lacuna.There is frustum valve nozzle (12) lower end, be fixed on the center of valve gap by nut (11), by rubber washer (10) sealing, there are rubber sheet gasket (14) and pipe cap (13) in the upper end of valve nozzle (12), pipe cap has at least one exhaust port on (13), in the outside of pipe cap (13) a no end cylindrical plastic bonnet (15) is arranged, just be placed on the valve gap (8).The upper end of valve nozzle (12) also can directly be drawn out to outside the wall with flexible pipe.
Claims (7)
