Abstract
The utility model discloses an automatic discharge valve for a central heating radiator. The center of a valve cove is provided with a valve port, a valve body is provided with a float, the upper end of the float is connected with a positioning needle with a sealing ring, and the end of the positioning needle is positioned under the valve port. The utility model has the advantages that the automatic air discharge is realized, the trouble of manual air discharge is eliminated, and the normal heating can be ensured, the heating efficiency is improved, and the utility model can prevent that water is stolen by people, and the environment is improved. The structure is simple, and the using performance is reliable.
Description
The utility model belongs to a kind of heating equipment annex, particularly a kind of heating installation bag valve air relief.
Heating phase in the winter time, every resident who stays in the building top layer is subjected to the puzzlement of " leaking informaton " to some extent, because the existence of air in the heating system, cause in the heating installation bag and be not fully filled water, form a cold, the phenomenon of one's own wishful thinking, therefore, when each boiler pump turns round, the resident of top layer wants manual operation, turn vent valve and leak informaton, could guarantee normally carrying out of heating, and the influence sleep of leaking informaton early morning, nobody leaks informaton or does not in time leak informaton in the family all influences heating, when manually leaking informaton simultaneously, leak informaton all has some water projections to come out befouling environment at every turn, and having the people to utilize this machine to steal water, the resident who also has causes spreading unchecked of water because of manual vent valve opens by mistake to open.
The purpose of this utility model provides a kind of valve air relief, removes the trouble manually leak informaton, and guarantees normally carrying out of heating, and simple in structure, usability is reliable.
The purpose of this utility model is achieved in that it includes the valve body of inlet, valve gap, its technological scheme main points are: there is a valve opening at the valve gap center, float is housed in the valve body, and the float upper end connects the register pin of band seal ring, and the register pin upper tip is positioned at the valve opening below.
The utility model has the advantages that: realize automatic vent, removed the trouble of manually leaking informaton, guaranteed normally carrying out of heating, improved heat supply efficiency, prevented from artificially to steal water, improved environment, and simple in structure, usability is reliable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the top worm's eye view of bolt.
See Fig. 1,2, concrete structure of the present utility model is as follows: the lower end of valve body 7 have one radially elbow be inlet 9, the upper end screw thread attachment valve lid 6 of valve body 7, the center has valve opening 5, the inside and outside end of valve opening 5 all has a conical surface 1, screw thread is screwed bolt top 4 on the valve opening 5, there is plane 10 its both sides, float 8 is housed in the valve body 7, float 8 is the cylindrical of lower ending opening, use the affixed register pin 3 of nut in the middle of its upper end, suit O-ring seal 2 on the register pin 3, the upper tip of register pin 3 is positioned at the below of valve opening 5.Working procedure: the utility model is installed on heating installation wraps, when the boiler pump brings into operation, there is wind freely to discharge from the valve opening 5 of valve gap 6 upper ends, when beginning water-filling in the valve, earlier with open type float 8 lower end closed, along with water level in the valve continues to rise, float also rises, on the conical surface 1 of seal ring 2 contact valve openings 5 lower ends on the float upper-end surface centralized positioning pin 3, realize the sealing action, water level raises gradually, and confining pressure increases thereupon, until complete closed, because the design of float volume is allowed some leeway, the water surface can not reach valve opening 5, can guarantee none leakage of dripping, when the stall of boiler pump, drawdown, water in the valve body 7 also flows in the heating installation bag, and float 8 is reduced to original position, prepares action next time.Register pin 3 on the float 8, the center is accurate in the time of can guaranteeing float 8 liftings.For defence leak into contingency, valve opening 5 places in valve gap 6 upper ends are screwed bolt top 4, do not tighten at ordinary times, gas is emitted from the top 4 both sides plane clearances of bolt, if any leakage, only need screw, the conical surface 1 of the tapered portion of bolt top 4 and valve opening upper end is fitted to seal and is got final product temporarily.
Claims (4)
1, a kind of heating installation bag valve air relief includes valve body, the valve gap of inlet, and it is characterized in that: there is a valve opening at the valve gap center, and float is housed in the valve body, and the float upper end connects the register pin of band seal ring, and the register pin upper tip is positioned at the valve opening below.
2, bleed valve according to claim 1 is characterized in that: float is the cylindrical of lower ending opening.
3, bleed valve according to claim 1 is characterized in that: the inside and outside end of the valve opening of valve gap all has a conical surface.
