Abstract
The utility model relates to an automatic gas exhausting and water cutting off valve for central heating. The exhaust valve in the prior art has complicated structure, and water leakage is generated due to sealing property affected by low sealing force. The valve core of the utility model is fixedly arranged on a float, a magnet is arranged on the valve core, the magnet is provided with a rubber pad, and the magnetic force of the magnet is smaller than the total weight of the float and the valve core. When an exhaust port is closed by the valve core, closing force equals to the sum of the buoyancy of the float and the magnetic force of the magnet. Since the closing force of the valve core is enlarged, sealing property is improved, and structure is simplified.
Description
The utility model relates to a kind of water heating system parts, particularly a kind of heating installation automatic vent sealing valve.
The heating installation outlet valve performance that exists in the prior art is unreliable at present, often because of water leakage phenomenon takes place in sealing force inadequately, and complex structure.
The purpose of this utility model is to provide a kind of heating installation automatic vent sealing valve of new structure, and it can strengthen sealability, realizes automatic vent and watertight purpose.
The purpose of this utility model is achieved in that it comprises valve body, spool, valve body lower portion has suction port, top has relief opening, it is characterized in that the bottom of spool and the float that light material is made are fixedly connected, magnet is equipped with on top, improves sealability for advancing one one, and rubber pad can also be housed on magnet.
The utility model adds magnet on the top of spool, and the magnetic force of magnet is less than the weight sum of float and spool, and after exhaust, spool seals relief opening like this, and its sealing force is equivalent to the magnetic force sum of float and magnet.And after water was discharged from valve body, the deadweight by float and spool made exhaust open.The utility model has strengthened the sealing force of spool when the sealing relief opening, and its sealability is improved, and structure also obtains simplifying simultaneously.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
As shown in Figure 1, valve body is made up of main valve body 7 and loam cake 2, between sealing gasket 3 is housed, and use bolt.The bottom has suction port 9, and top has relief opening 1.Float 8 and spool 10 are housed in the valve body.The lower end of spool 10 and float 8 are fixedly connected.The upper end has a groove 6, and interior dress magnet 5 is with rubber pad 4 on magnet 5, in the internal fixation of loam cake 2 guide sleeve 11 is housed.
During work, the air in the water heating system at first passes through suction port 9, and main valve body 7 is discharged from relief opening 1, and when air arrange, water promptly enters main valve body 7, and float 8 drive spools 10 move upward, and relief opening 1 is sealed.Its seal force is equivalent to buoyancy and magnetic force sum.Because seal force increases, so sealability is improved.
Claims (2)
1, a kind of heating installation automatic vent sealing valve comprises valve body and spool, and valve body top has relief opening, and the bottom has suction port, it is characterized in that the bottom of spool and the float that light material is made are fixedly connected, and magnet is equipped with on spool top.
2, according to the said heating installation automatic vent of claim 1 sealing valve, it is characterized in that being equipped with above the magnet rubber pad.
