Abstract
The utility model relates to an air exhaust valve for heating pipelines. The ball type closing valve of the common air exhaust valve is provided with a hand-operated adjustable rod. The hand-operated adjustable rod extends out of the shell body of the valve along the air exhaust hole. The foreign body of the ball type closing valve is cleared off through the hand-operated adjustable rod which is adjusted to cause the ball type closing valve to act. Thus, the valve and the air exhaust hole generate no clearance, and the ejection of the water column is not caused. The opening of the air exhaust hole is provided with a sewage treatment cup with a sewage draining opening, which prevents the sewage from ejecting. The side wall of the shell body of the valve is provided with a transparent observation window and a detachable sealing glue cover. The utility model has the advantages of safe use, convenient maintenance, long service life, etc.
Description
The utility model is the outlet valve of using on a kind of caliduct.
At present, employed outlet valve on caliduct mostly is a float-ball type.Utilize the throttle down that is used for of floating ball lever power.Valve is generally ball formula throttle down.Caliduct is when heating, owing in the pipeline foreign material are arranged, these foreign material are bonded on the ball formula throttle down, can make between its sphere and the vent ports and produce the gap, in valve, have water not have under the gas situation, when particularly after power failure, resetting the heating water pump, because the gap between valve and the vent ports, can cause the water column ejection, be sprayed onto on roof and the wall, bring very big loss to the user.
The purpose of this utility model provides a kind of adjustable automatic control pressure vent, and this valve can be removed the foreign material on the valve in use, can not produce the gap between valve and vent ports and causes the ejection of water column.Have safe in utilization, the user is relieved, and is easy to maintenance, advantages such as long service life.
Main points of the present utility model are that a manual adjustable rod is installed on the ball formula throttle down on the common outlet valve, manually adjustable rod is outside exhaust port stretches out valve chest, can save manual adjustable rod with hand adjustment and make the action of ball formula throttle down, so that the foreign material on the ball formula throttle down are disposed.So can between valve and exhaust port, not produce the gap, also not therefore reason cause the ejection of water column.
Below in conjunction with accompanying drawing further instruction again.
Accompanying drawing 1 is the plan view of adjustable automatic control pressure vent.
Accompanying drawing 2 is the plan view of adjustable automatic control pressure vent.
As can be seen from Figure 1, this adjustable automatic control pressure vent is the same with common outlet valve, be on valve chest 14 inner roof walls, drain tap main body 7 to be housed, an exhaust port 16 is arranged in the drain tap main body, aperture and valve chest are interlinked to the outside on it, it communicates in aperture and the valve chest down, one hollow float 11 is arranged in valve chest, it is hinged with the fixing rod 17 on the fixing drain tap main body that described hollow float is communicated with lever 9 by ball float, the one ball formula throttle down 8 that is complementary with following aperture is arranged at the place, following aperture of exhaust port, described ball formula throttle down is connected with the concentric hole that ball float is communicated with on the lever in movingly mode by the pin of fixing on it 10, unload the mouth of a river 12 on the diapire of valve chest, sidewall has mount inlet 13.The utility model is to carry out following improvement on the basis of common outlet valve, along exhaust port a manual adjustable rod 2 is installed on ball formula throttle down thereby housing is outer.In use, this outlet valve is installed in the caliduct, in valve chest, enter water after, utilize the control valve that is used for of floating ball lever power to carry out exhaust venting, when water level improves in the valve chest, no gas valve is closed naturally; When water level reduces in the valve chest, there is gas to discharge automatically.Hold adjustable rod handle 4, can make the upper and lower action of ball formula throttle down, or the action of left-right rotation, in case be stained with foreign material on the ball formula throttle down, make the action of ball formula throttle down by manual adjustable rod, make like this to produce friction between the following aperture of ball formula throttle down and exhaust port, foreign material are disposed, thereby guarantee that automatic control pressure vent normally moves.
Find out from Fig. 1, Fig. 2, the sewage treatment cup 5 that above orifice part is the bottom is installed at the place, aperture on exhaust port 16, has sewage draining exit 19 in the side lower end of sewage treatment cup, can be connected to drain pipe 6, and on manual adjustable rod 2, the reflection of spray sewage is housed and covers 3, relative with the last aperture of exhaust port.Said structure is just in case have under the situation of water column ejection, can play safety effect.Just when the malfunctioning ejection that causes water column of valve inner structure, because stopping of spray sewage reflection lid makes sewage export to the blowdown ditch from sewage draining exit along drain pipe, thereby guarantee safe in utilizationly, near the wall room the outlet valve is not contaminated.
As can be seen from Figure 1, a sidewall at valve chest 14 is equipped with transparent windows 1.Viewing window generally is to adopt plexiglass, is fixed on by fixing bolt 15 on the sidewall of valve chest, can observe air content size in the caliduct by viewing window, and the height of water level is convenient to carry out the processing of emergent accident in the valve.
From Fig. 1, demountable sealer lid 20 is housed on another sidewall of valve chest, mount inlet 13 is opened at demountable sealer and is covered.Sealer lid can adopt the lid that has certain gradient with mouthful cooperate installation, or employing screw thread mode compresses seal ring and installs.In case main effect is when in the discovery valve impurity that hinders exhaust being arranged, to open the sealer lid very easily, repairs fast, avoids changing the unnecessary loss of entire product.
In a word, this adjustable automatic exhaust valve, in use safe and reliable, use generally speaking the proper water column ejection that do not have. Both just just in case the water column ejection is arranged, the sewage disposal cup as safeties was arranged again, sewage can be led away, and be unlikely and pollute the wall room, and made the user relieved. And the advantages such as easy to maintenance, long service life are arranged.
