Description
Technical field
The utility model relates to a kind of solar energy vacuum tube booster automatic water plugging safety valve, especially can prevent that solar water heater or solar water-heating system from leaking and paralysing in a large number because of solar energy vacuum tube booster.
Background technique
At present, as everyone knows in solar water field, because the initial input of solar energy vacuum tube heat collector is lower, so be widely used in solar water heater and solar water-heating system.But it also has its prospect of the application of serious drawbacks limit, wherein the most serious problem is exactly a solar energy vacuum tube booster, just can cause whole solar water heater or solar water-heating system paralyse or cause security incident because leaking in a large number.
Summary of the invention
Cause whole solar water heater or the solar water-heating system problem of paralysing of leaking in a large number in order to overcome because of solar energy vacuum tube booster, the utility model provides a kind of solar energy vacuum tube booster safety valve, this solar energy vacuum tube booster safety valve can be in the time of solar energy evacuated pipe explosion, this solar energy vacuum tube of self-closed, prevents that whole solar water heater or solar water-heating system are because leaking and paralyse in a large number.
The utility model solves the technological scheme that its technical problem adopts: one end is the blocking cap of center drilling, tapping connects inner tube, inner tube the other end overcoat inner tube seal ring, inner tube liner inner tube support plate, inner tube support plate center is porose, inner tube connects blocking cap one end and is provided with blanking cover, blanking cover diameter is greater than diameter of inner pipe, between blanking cover and inner tube, be provided with blanking cover sealing gasket, there is bar at blanking cover center, through inner tube support plate center hole, fluted on bar, between groove and inner tube, there is spring locking plate, thereby form one with unidirectional and solar energy vacuum tube booster safety valve auto-lock function.Insert in solar energy vacuum tube by inner tube and inner tube seal ring solar energy vacuum tube booster safety valve one end, solar water container is inserted in blocking cap one end, in the situation that solar energy vacuum tube is intact, because solar energy vacuum tube booster safety valve two ends hydraulic pressure is basic identical, blanking cover is locked in normally open by spring latch sheet, in the time of solar energy evacuated pipe explosion, because inner pipe water pressure declines suddenly, cause blanking cover to be closed under the effect of hydraulic pressure, the blanking cover of spring latch sheet locking simultaneously, reach the damaged solar energy vacuum tube of sealing, stop whole solar water heater or solar water-heating system to leak in a large number and paralyse or cause the object of security incident.
The beneficial effects of the utility model are, can, after solar energy evacuated pipe explosion, seal rapidly damaged solar energy vacuum tube, stop whole solar water heater or solar water-heating system paralyse or cause security incident because leaking in a large number.
