Description
The utility model relates to a kind of automatic water-saving control valve that is mainly used in a kind of water inlet and outlet of closing automatically behind solar thermal collector or its water tank filling up water, opening automatically during user's water.
At present, known to solar thermal collector Shang Shui, close hydromining and prevent that with following three kinds of forms the sealing spill-over goes out, it is:
One. adopt the mode of alarm, this method sounds the alarm alarm after mainly expiring by water, and warning is used
Family water is full, and the user removes to bar up the into gate valve at water place then.
Two. adopt the method for straight-through type.This method is fairly simple, its working principle be solar thermal collector or
The vent hole place of its water tank highest point meets a pipe direct user toilet or the place that discharges water, and water is completely back just from this
The root pipe flows to the toilet or the place that discharges water, and the user closes the gate valve at water place then.
Three. adopt the method for float type.This method is fairly simple, its working principle be solar thermal collector or
Its water tank highest point connects the device of a band float, and water completely back float floats, and closes into water pipe, plays the pass
The purpose of closing adopts this mode to need two water pipes of water inlet and outlet to realize the volume ratio that control section accounts for
Bigger, and expense is also high.
Above-mentioned three kinds of controlling methods have problems in technology, make troubles to the user especially in the use.
The purpose of this utility model provides a kind of automatic water-saving control valve, and it is closed after can not only making solar thermal collector or its water tank filling up water automatically, open automatically during user's water, and and the safety of automatic protection heat collector or its water tank is arranged.And simple, the more preferably use of solar energy, popularization provide reliable assurance.The purpose of this utility model is achieved in that the automatic water-saving control valve is made up of main control valve and Safety control valve two-part, divides two-part to install.Main control valve is installed in the water inlet and outlet place of solar thermal collector or its water tank, this valve of water turnover all passing through of solar thermal collector or its water tank; Safety control valve is installed in the air vent place of solar thermal collector or water tank, and the water the when air of solar thermal collector or its water tank and water are full all passes through this valve.When water enters water cavity B from water cavity A, restrictor ring is under the effect of hydraulic pressure, form one-way throttle with sealing gasket (1), water through throttling enters water cavity B, enter water cavity C by water cavity B then, enter solar thermal collector or its water tank by the hole of water cavity C on the stem stem face of location, water yield increase along with solar thermal collector or its water tank, the spring that is contained in the main valve plug is compressed under the effect of hydraulic pressure, when spring is compressed to certain position, form restriction between the end face of location core and the sealing gasket (2), the pressure of water cavity B is greater than the pressure of water cavity C like this, and spring further compresses, nut, pressure pad (1), sealing (2), pressure pad (2), setscrew nut is made dead axle with main valve plug and is moved to the location, sealing gasket (2) contacts with the part of core lower end surface, location projection and seals into water, thereby reaches the purpose of closing automatically.If the water yield is increased to predetermined amount main control valve when also not closing, water enters Safety control valve, and this moment, float floated, and contact with the part seal ring, and the sealing current are assisted closing of main control valve.If the float in the safety valve contacts when sealing current with seal ring, main control valve is not also closed, and prove that the automatic water-saving control valve has fault this moment, needs to adjust or repair.At this moment enter the water jack-up seal ring of water cavity E, pressure spring, current enter air cavity F from the slit between seal ring and the liner by water cavity E, thus protection solar thermal collector or water tank; During user's water, the hole that water flows out in solar thermal collector or its water tank on the stem stem face of location enters water cavity C, enters water cavity B by water cavity C again, and restrictor ring moves down under the effect of negative pressure; Nut,
Pressure pad (1), sealing gasket (2), pressure pad (2), setscrew nut are made dead axle with main valve plug and are moved to the location, sealing gasket (2) breaks away from the end face of location core, current enter water cavity B from water cavity C, enter water cavity A from water cavity B again, flow out turnover water pipe at last, thereby reach the purpose of automatic connection current.
Owing to adopt such scheme, do not worry all inconvenience of solar energy when last water in use.And simple in structure, control is reliable, and is easy to use.Below in conjunction with drawings and Examples the utility model is further specified.
