Abstract

The utility model provides a shutoff drainage valve and a hand control device thereof, relating to a solar water heater pipeline drainage device. A penetrating valve body is not needed. A water outlet in a water tank is provided with a valve plug with a guiding sleeve. Water source of the pipeline is shut off. An air interface above the water tank is altered to be connected with a valve cover. One end of a hollow plug rod is communicated with the valve plug. The other end of the hollow plug is connected with a fiber group clamp to the valve cover for sending atmosphere to the pipeline. The fiber group is clamped. An air valve is not needed. The valve cover is provided with an overflow port. The top end of the valve cover is provided with a pulley. A pressing spring is arranged between the fiber group clamp and a pulley seat. The water outlet is compelled to be normally closed. The direction of the fiber group is altered by the pulley through the hole of the pulley seat. The fiber group penetrates the wall, is locked with the pulley seat by a connecting pipe from the wall outside from high to low, and is connected with, a crank ratchet which is fixed indoors. Electric drive is not needed when the water is used. One angle of the crank needs to be rotated by hand. The valve plug is dragged to move upward by the fiber group. Hot water flows into the pipeline. Users can get hot water just at the first time. A cam pawl is lifted before users finish using. The crank and the valve plug reset automatically. The water outlet is closed, and the pipeline is exhausted.

Description

No body formula dam exhaust-valve and hand-control device thereof

Technical field the utility model designs a kind of solar energy water heater pipe emptier.Especially need not to connect valve body, need not air valve, need not motor-driven valve, winter, pipeline did not freeze stifledly, and one to open be exactly the pipeline exhausting device of hot water.

The present known pipeline exhausting device of background technology is realized by motor-operated control valve, magnetic valve, and is freezing for anti-valve body owing to this kind device is located at by the water tank outer vent, added the electric heating frost box; Electric device fault rate height, magnetic valve more so in case go wrong, need device and frost box thereof are pulled down transposing in the lump, and it is all high not only to make maintenance complexity but also expense; This device not only can not be enabled when having a power failure, and in magnetic field stronger local performance failure, cause water heater can not use fully during this period on the contrary, catch up with winter and pipe freezeup certainly will occur.The restriction in power supply, magnetic field is broken away from the solar energy water heater pipe emptying, embodies its stable independently effect, is that practicality need be in the reflection in technical staff's brains.Yet it is not only a kind of method, and is a kind of concrete capable bit architecture.

Summary of the invention is a kind of be goal of the invention solar energy water heater pipe emptier with the restriction of breaking away from power supply and magnetic field, simple in structure, cheap, easy to operate, maintenance easily, by delivery port in the water-heater water tank valve plug is set and ends pipeline water source; Change and set out mouth of a river center line top air interface and be connected with the valve gap that is provided with overfall, plug and tow cartoon are pipeline bubbling air, fastening tow to the valve gap inner chamber between connecting with logical heart stopper rod; The valve gap top is provided with universal pulley, is provided with the compression spring between the Shu Kayu pulley base, and hydraulic pressure forces valve plug to be in the below extreme position in the case in addition, and the delivery port self-locking is normally closed, jumps a queue as thermos flask, and stifled adiabatic amount runs off; Tow changes direction by the pulley base centre bore through universal pulley, reduces friction, big-endian is locked the crank non-return ratchet of fixing in the junction chamber outward within the walls with pulley base by adapter, packing ring break-through by wall, need only angle of rotating crank during water, move beyond the Great Wall by the tow drawing valve, the hot water flow ipe, one to open be exactly hot water, use up prerequisite and play the non-return ratchet, crank, Yan Sai automatically reset by the expense of pressing, and delivery port is closed, tube emptying.Expand vast northern market for solar water heater, the technology prerequisite is provided.
