A kind of water route switch valve
Technical field
The present invention relates to electric water heater manufacturing technology field, especially a kind of water route switch valve that applies to quick electric water heater.
Background technique
Usually, the switch valve that is used in the water route common are the products such as ball valve, angle valve, solenoid valve, ball valve, angle valve during because of operation required torsion larger, the frequent switching easily damaged, generally use in the occasion that seldom opens and closes, therefore being not suitable for being applied to quick electric water heater etc. needs the occasion that often opens and closes; And solenoid valve is suitable for frequent opening and closing that to use be quick electric water heater switch valve commonly used, but it need to cooperate switch to use, and overall cost is higher, simultaneously because existing the electric leakage risk can reduce the Security that quick electric water heater uses.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of water route switch valve, low cost of manufacture, and flexible operation is laborsaving, and the occasion that is suitable for often opening and closing is used.
For achieving the above object, technological scheme of the present invention is: a kind of water route switch valve, comprise valve body, switch base, valve body is provided with intake tunnel and exhalant canal, the exhalant canal of valve body is communicated to the centre of valve body from the outside, the intake tunnel of valve body is communicated to periphery and the top that is in the middle exhalant canal of valve body from the outside, in the valve body in the middle of the valve body above the exhalant canal elastomer seal is housed, the elastomer seal end face is provided with the control through hole of corresponding valve body exhalant canal and the excessively water through hole of corresponding valve inleting water passage, switch base is contained on the valve body above the elastomer seal and pushes down the edge of elastomer seal, a depression bar that can move up and down along switch base is equipped with in the centre of switch base, sealing plug is equipped with in the lower end of depression bar, the outer positioning component that depression bar is located up and down that connects of switch base is stretched out in the upper end of depression bar, and its lower end sealing plug can seal up the control through hole of elastomer seal end face and drive elastomer seal and seal up the middle exhalant canal of valve body after described depression bar moved down and puts in place.
Further improve, described elastomer seal is made of with the circular reinforced seat that is enclosed within centre above the diaphragm the diaphragm of plate-like, the edge of diaphragm is pressed between valve body and the switch base, described control through hole is arranged in the middle of the circular reinforced seat end face and is communicated to the middle exhalant canal of valve body, and the described water through hole of crossing is arranged on the intake tunnel that circular reinforced seat end face is controlled the through hole side and is communicated to valve body.Can improve intensity and the planeness of elastomer seal intermediate portion, better match with the sealing plug of depression bar and the exhalant canal of valve body.
Further improve again, the centre of described reinforced seat lower end surface and both sides are provided with three socket projections, corresponding position is provided with three socket through holes in the middle of diaphragm, described reinforced seat utilizes protruding the matching with three socket through holes of diaphragm end face of three sockets of lower end surface that reinforced seat and diaphragm are fitted, described reinforced seat end face control through hole is communicated to the lower end of the socket projection in the middle of the reinforced seat lower end surface, and described reinforced seat end face is crossed the water through hole and is communicated to the in addition lower end of one of them socket projection of two socket projections, reinforced seat lower end surface.Make things convenient for reinforced seat and diaphragm to socket-connect.
Preferred described diaphragm is made by rubber, and described reinforced seat is made of plastics.Both reduce manufacture cost, and can guarantee again the reliability of elastomer seal action.
Further improve, between described depression bar and the switch base seal ring is housed.Can prevent that water leakage phenomenon from appearring in switch base.
Further improve, a side of described valve body is provided with mounting hole.The installation location of convenient whole switch valve.
Preferred described positioning component comprises the depression bar cover that fixes with switch base, the upper end of depression bar cover is provided with a shoulder hole, the ratchet that is enclosed within the depression bar upper end is equipped with in the centre of depression bar cover, depression bar is connected in the rotating mode of axially-fixed and radial with ratchet, cover has spring on the depression bar between ratchet and the switch base, on the upper end shoulder hole of depression bar cover a briquetting being housed, matches with described ratchet with ratchet in the lower end of briquetting, and it is outside that the depression bar cover is stretched out in the upper end of briquetting.So that operation is more simply laborsaving.
The present invention is owing to adopting depression bar to match with control through hole on the elastomer seal, when the control through hole on the sealing plug sealed elastic Sealing of depression bar end, depression bar drives again the intake tunnel of elastomer seal sealed valve body, and intake tunnel and the exhalant canal of the valve body that makes are isolated; When the control through hole on the sealing plug disengaging elastomer seal of depression bar end, Unloading Effect by the control through hole, so that the hydraulic pressure below the elastomer seal greater than the hydraulic pressure above it, utilizes hydraulic pressure that elastomer seal is upspring, the intake tunnel of valve body and exhalant canal directly are connected; Therefore the present invention utilizes the movement of hydraulic pressure and depression bar to realize closing and opening of water route, thus depression bar to move required power just little, flexible operation, safe to use.
On the other hand, move up and down to realize closing and opening of water route because adopting elastomer seal, operating frequency can be higher, and its occasion that is suitable for often opening and closing is used, as is used on the quick electric water heater.
