Abstract

The utility model discloses an emptying valve used for preventing water feeding and discharging pipes of a solar water heater from freezing. It is installed in a water tank through a vacuum pipe installation hole. The water outlet of the valve is fixedly connected with the water inlet and outlet pipe head of the original water tank through a section of flexible pipe, the other end of the valve is provided with a pipe orifice, the pipe orifice can be exposed out of the water surface or submerged in the water through a position changing device on the valve, when the pipe orifice is exposed out of the water surface, the water is emptied, and when the pipe orifice is submerged in the water, the water is used. Therefore, the movable sealing opening which needs to be opened and closed every time is not arranged below the water surface, so that the problem of reliability is solved, and the valve is not possible to freeze because the valve is arranged in the water tank.

Description

The swing type exhaust-valve

The utility model is a kind of valve that is used for solar water heater.

Along with the enhancing of whole society's environmental consciousness, use the people of solar water heater more and more, particularly vacuum tube, heat pipe solar energy water heater are popularized very fast at northern area.But they have a common problem is to be exposed at outdoor upper and lower conduit will freeze winter, and the product that the original four seasons can both heat production water but can not play a role winter, and its power savings advantages can not be given full play to, and has influenced market and has further expanded.At present, for head it off, it is several to comprise that my development product sample has, through on probation all unreliable: adopt the direct current type water intaking, situation about being not closed completely is arranged, adopt siphon off water, the situation of cutout is arranged during high water temperature small flow.So this problem still there is not solution so far.

The purpose of this utility model, just provide a kind of reliable performance, easy for installation, cheap, can drain-solar water heater the device of upper and lower conduit.

For achieving the above object, thinking of the present utility model is: the fixedly mouth of pipe of the inner water inlet and outlet of present solar water heater water tank is changed into the movable mouth of pipe that can surface or not have in the entry by displacement device and flexible attachment components; When the mouth of pipe surfaces, can the emptying upper and lower conduit, when the mouth of pipe does not have in the entry, can the direct current water intaking.

The technological scheme that adopts is: an end of flexible pipe is fixedlyed connected with the former fixedly mouth of pipe, and the other end is fixedlyed connected with the water outlet on the valve body of the present utility model; In the inside of valve body or outside being provided with the mouth of pipe surfaced or do not have displacement device in the entry.

Above-mentioned displacement device is: in the core chamber that communicates with the mouth of pipe on valve body slide core and sliding pin are housed, on the cylindrical of slide core chute is arranged, by the cooperation of chute sliding pin, make slide core that two stop places of height be arranged, just can close or open the inner nozzle that communicates with valve pocket; There is a vent also to communicate in addition with valve pocket.

Above-mentioned displacement device also can be an outer rod member that is driven by external force of valve body.

The advantage of this scheme is: each connection part below the water surface all is fixedly connected, and the movable sealing port that does not have each use all will open or close the situation that causes being not closed completely and leak because of reasons such as impurity in the water can not occur, so emptying is reliable.When water, be again the direct current water intaking, the water outlet smoothness.Because the new product of this practicality can directly be contained in the common water tank, therefore easy for installation, valve itself can not freeze yet.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Accompanying drawing 1 is the emptying state schematic representation of the utility model submarine formula structure;

Accompanying drawing 2 is water view of the utility model submarine formula structure;

Accompanying drawing 3 is the utility model swing link type structural representations.

As shown in Figure 1: core chamber (8) is arranged on the valve body (1), the mouth of pipe (9) communicates with middle part, core chamber, the inner nozzle (3) of bottom, core chamber communicates with valve pocket (4), link to each other with flexible pipe (5) again with the water outlet (6) that valve pocket communicates, also have a breathing pipe (7) one ends to lead to the above atmosphere of the water surface in addition, an end communicates with valve pocket.Slide core (2) is housed in the core chamber, chute (11) is arranged on the slide core cylindrical, the sliding pin (10) that is fixed on the core cavity wall just is inserted in the chute, shown in circle among the figure.Also be provided with tank on the slide core cylindrical.

When slide core is in as shown in Figure 1 low level, the slide core bottom surface is blocked inner nozzle (3), at this moment open shower nozzle, because drop is bigger, the water in the valve pocket (4) just is sucked away from upper and lower conduit through flexible pipe, even if what this moment, the inner nozzle was blocked up is not tight, also far fewer than the water that is siphoned away from valve pocket by upper and lower conduit, air just enters valve pocket from breathing pipe (7) as a result, generation buoyancy from the water that leaks valve pocket here, whole valve just upwards floats pendulum, the mouth of pipe with the core chamber is suitable for reading surfaces.Be emptying state this moment.

Next time, during water, by adding water slide core to upper punch once, because leading role of each prominent point of chute, sliding pin just hung over sliding poor middle part again, and slide core just has been parked in a high position, as shown in Figure 2.This moment, opened fully the inner nozzle, and water just flows into valve pocket from the mouth of pipe and core chamber through the inner nozzle, shown in arrow among the figure.At this moment the water that flows to valve pocket enough replenishes the water that is siphoned away from valve pocket, water abrim all the time in the valve pocket, and valve body material is heavier than water in addition, and whole valve does not all have in the entry.Here it is water intaking state.This water-supply method is the same with existing common water heater water-supply method, the water outlet smoothness.

Moisturizing in water tank after a bath, slide core are closed priming valve just by to upper punch, and slide core is landing downwards just, because the effect of chute, slide core is got back to low level as shown in Figure 1 again, blocks the inner nozzle, opens shower nozzle, and whole valve will float pendulum to the water surface, is emptying state again.

In accompanying drawing 3, displacement device is the outer hinged rod member (2) of valve body (1).By external force such as electromagnet, motor, make valve body swing, the mouth of pipe (9) is surfaced or do not have in the entry.

Certainly, the utility model is not only limited to the above embodiments, so long as the mouth of pipe is surfaced or do not have technological scheme in the entry by displacement device and flexible attachment components, all belongs to protection domain of the present utility model.
