Abstract
The utility model relates to a solar water heater emptying valve which comprises a valve body and a piston; wherein a partition with a center hole is arranged at the middle part of a cavity of the valve body; a piston pad is arranged at the lower end of the piston and is positioned in a piston bush which is arranged at the lower part of the partition; a rod body of the piston upwards penetrates through the center hole of the partition, and the upper end of the rod body is connected with a floater; an upper water opening and a lower water opening which are communicated with the cavity are arranged at the lower end of the valve body; a water outlet communicated with a part of the cavity, which is higher than the partition, is arranged at one side of the upper part of the valve body; an emptying opening is arranged at the upper end of the valve body; and a single-way valve is arranged in the emptying opening. According to the solar water heater emptying valve, the pressure of tap water is used to control the emptying of the upper water pipe and the lower water pipe of a solar water heater, and no additional energy source is required; the solar water heater emptying valve has the characteristics of energy conservation, environment protection, safety, firmness and durability; and in addition, the emptying valve is simple in structure and low in production cost so as to be suitable for wide popularization.
Description
Technical field
The utility model relates to a kind of hydraulic pressure control solar water heater emptying valve, can prevent winter to freeze stifled or bursting by freezing to the emptying of solar water heater upper and lower conduit.
Background technique
The solar water heater upper and lower conduit water capacity of time the inside in the winter time is prone to build-up ice, freeze stifled influence up and down water use, the upper and lower conduit bursting by freezing just need repairing, increase the manpower and materials input, for this reason, a lot of solar water heaters have increased exhaust-valve.Existing exhaust-valve has electromagnetic type exhaust-valve, full-automatic electronic valve, heating tape exhaust-valve, respectively have superiority, but maximum problem is a complex structure, needs consumed power, usually uses the 220v power for illumination, because Environmental Conditions is moist, has potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic pressure control solar water heater emptying valve, solves solar water heater upper and lower conduit emptying problem, avoids the use of electric power.
The purpose of the utility model realizes as follows: a valve body is arranged, and there is the dividing plate of band mesopore at the body cavity middle part, and the piston of a lower end band piston pad is arranged; Piston pad is in the piston sleeve of the lower partition; Mesopore and upper end that the body of rod of piston is upward through dividing plate are connected with float, and the lower end of valve body is provided with the mouth of a river up and down that communicates with inner chamber, the water outlet that the top one side setting of valve body is communicated with the above inner chamber of dividing plate; The upper end of valve body is provided with evacuation port; Emptying Oral appliances one-way valve, one-way valve from valve body to the outside direction of evacuation port by, and open to the direction of valve inner from evacuation port.Water outlet connects solar water container; The mouth of a river is connected to the mixed water valve of water and water on the room through upper and lower conduit up and down; Evacuation port connects the emptying pipe of a band exhaust-valve, and the emptying pipe upper end is higher than cistern water level, through emptying pipe the water of drawing is controlled; Can be with the upper and lower conduit emptying, normal water again.
The utility model need not other the energy with the pressure control solar water heater upper and lower conduit emptying of tap water self, energy-saving and environmental protection, safety, and simple in structure, sturdy and durable, cost of production is low, suitable extensively popularization.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to Fig. 1, a valve body is arranged, there is the dividing plate of band mesopore at the body cavity middle part; The piston 5 that a lower end band piston pad 6 is arranged, piston pad 6 are in the piston sleeve 7 of the lower partition, and mesopore and upper end that the body of rod of piston 5 is upward through dividing plate are connected with float 4; The lower end of valve body is provided with the mouth of a river up and down 3 that communicates with inner chamber; The water outlet 2 that the top one side setting of valve body is communicated with the above inner chamber of dividing plate, the upper end of valve body is provided with evacuation port 1, device one-way valve 8 in the evacuation port 1.Water outlet 2 connects solar water containers, and the mouth of a river 3 is connected to the mixed water valve in room through upper and lower conduit up and down, and evacuation port 1 connects the emptying pipe of a band exhaust-valve.
A. go up water: when last water, the piston 5 in the valve body is in the piston sleeve 7, in order to avoid go up the direct impact piston 5 of water piston 5 is moved upward, and therefore can avoid piston 5 to move upward and block water on the dividing plate mesopore.When solar water container is full of water, because piston 5 upper end floats 4 receive floating function, piston 5 is moved upward, piston 5 lower ends will be blocked the dividing plate mesopore and stop upward water, prevent to forget and close water supply valve and spilling water.
B. emptying: the exhaust-valve on the emptying pipe is opened; Make emptying pipe and atmosphere, the round mouth 1 of valve body is connected with atmosphere, and the tap of fetching boiling water then discharges water; Water level in solar water container is identical with water level in the valve body or when being lower than its water level slightly, upper and lower conduit will be drained.
C. water: under the state of upper and lower conduit emptying, open and mix water on the water valve, treated for 6-7 seconds after, stop to go up water.Then the mixed water valve handle of solar water heater is moved on to down water level and put, the control exhaust-valve on the emptying pipe is closed, the tap of fetching boiling water again discharges water, and when treating out hot water, turns off the tap, and then opens and mixes water under the water valve, gets final product bathing.
D. it is for use to cut off the water: in water utilizing process, it is for use to cut off the water sometimes, at this moment, and the only moving water valve that mixes.Because one-way valve 8 is housed in evacuation port 1, water can not pour in the emptying pipe.Otherwise, in the moment of cutting off the water the water in the water tank is poured in the emptying pipe, because in water utilizing process; The relative water tank of emptying pipe is a negative pressuren zone, so cut off the water suddenly, the water in the water tank can pour in the emptying pipe; Make emptying pipe become sewer; Up to intact the current in the water tank, an one-way valve 8 has been arranged just, water is kept off in valve body.
