Abstract
The utility model discloses a manual and automatic air exhausting device, which is composed of an air exhaust valve and a connector. A lever, a filter screen, a water baffle plate, and a floating body are arranged in a valve body of the air exhaust valve. A manual pull rod is arranged on the upper part of the valve body, and a valve core is arranged at the lower part of the valve body. The connector is an elbow with three connecting mouths. The utility model can be arranged on a heating pipeline for exhausting detention air. Thus, radiators are smooth, and heat supply effect is good.
Description
The present invention relates to the pipe fitting production technology, a kind of specifically caliduct venting gas appliance.
At present, the outlet valve of adorning on the heating pipeline mostly is automatic control pressure vent, but there is following shortcoming in this outlet valve: 1, automatic control pressure vent is malfunctioning sometimes, manually exhaust, and pipeline water flowing, ventilation are not smooth, heating installation is not warm thereby cause.When 2, running in air valve on the heating pipeline now, threeway, joint door need be arranged, to silk, therefore by adorning time-consuming taking a lot of work.3, the water in the existing outlet valve does not produce mobilely, is unfavorable for exhaust.
The purpose of this utility model be want to provide a kind of promptly can be manual, again can self-bleeding heating installation outlet valve, and convenient, fast during by dress.
The technical solution of the utility model is as follows:
This device is made up of two-part, and a part is an outlet valve, and a part is a link.Outlet valve mainly contains valve body, letter, manual draw bar, spring, smoke releasing cap, counterweight lead, buoyancy aid, lever composition.Its automatic vent principle is for when being filled with gas in the deferent, and buoyancy aid falls, the terminal whereabouts of lever, and the passage of gas from believe son flows to exhaust port and emits.When the manual exhaust of need, the pulling pull bar moves letter backward, and gas is both from believing that slit flow is discharged to exhaust port between son and the valve gap.
Link is that valve core and manger board are equipped with in an inside, and the elbow of connection mouth is arranged at top, current is unlikely forms the flowing state of choking with resentment; During maintenance,, needn't sluice because the effect of spring still can reach sealing.
The utility model has the advantages that when the automatic control pressure vent exhaust effect is bad, can utilize manually exhaust of stay cord (as needn't pedal height, needn't dismantle radiator box) easily, guaranteeing that heating installation is unobstructed, and save silk, joint door during by dress, accomplish saving of labor, laborsaving.
Below in conjunction with accompanying drawing the utility model is further explained:
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
As can be seen from Figure 1, upper half part of this device is an outlet valve, and lower half portion is a link.Outlet valve mainly contains compositions such as valve body 10, letter 3, manual draw bar 1, spring 5, smoke releasing cap 4, counterweight lead 9, buoyancy aid 16, lever 8.There is buoyancy aid 16 valve body 10 inside, lever 8 is arranged in the exhaust valve cap 6, between lever 8 and the buoyancy aid 16 counterweight lead 9 is arranged, lever 8 also is connected with level 3, on the manual draw bar lid 2 manual draw bar 1 is housed, around letter 3 spring 5 is arranged, believing on the valve body 10 of sub 3 bottoms has smoke releasing cap 4, has a filter screen 11 to be positioned at buoyancy aid 16 bottoms in the valve body 10, prevents that exhaust port is blocked, valve body 10 1 sides have one three cowling 12, in order to laterally convenient by dress.
The Lower Half of this device is a link, it is the elbow 15 that three connection mouths are arranged above, a valve core 14 is arranged in the elbow 15, spring 5 is arranged around the valve core 14, in the valve body 10, all there is manger board 13 joint of link and valve body 10, flows to guarantee that current form in device, make the manger board both sides produce pressure reduction and do not form the phenomenon of choking with resentment, sign 7 is a seal ring among the figure.
As can be seen from Figure 2, this device is a manual venting gas appliance, mainly form by valve body, manual draw bar, letter, smoke releasing cap, concrete structure is on the manual draw bar lid 2 manual draw bar 1 to be housed, letter 3 is arranged in the valve body 10, around letter 3 spring 5 is arranged, a smoke releasing cap 4 is arranged on the valve body 10, valve body 10 bottoms are connected with an elbow 15 that three connection mouths are arranged, and number in the figure 7 is a seal ring.
