Description
Technical field
The utility model relates to a kind of preventing absorbing shrinkage safety valve of heat-preserving water tank for solar water heater.
Background technology
In the use of existing attemperater, often there will be following phenomenon, when the water temperature in water tank reduces, the air pressure in water tank will be caused to reduce, and then cause water tank flat by suction under the effect of inner and outer air pressure.In the prior art people by arranging blast pipe on water tank, to prevent water tank from being inhaled flat.But so also can have following problem: when cold weather time, blast pipe can be freezed by steam, so just can not play the effect of balanced reservoir inner and outer air pressure.
Summary of the invention
The utility model, in order to solve the problem, proposes a kind of preventing absorbing shrinkage safety valve of heat-preserving water tank for solar water heater, and this apparatus structure is simple, easy to operate, can be good at solving water tank and is inhaled flat problem.
A preventing absorbing shrinkage safety valve for heat-preserving water tank for solar water heater, the utility model is characterised in that, the rainhat comprising sleeve pipe and be connected with sleeve pipe; Mounting A, mounting B is respectively equipped with at the two ends of the inner chamber of sleeve pipe; Mounting A, mounting B offer slotted eye A, slotted eye B respectively, is provided with glue gasket in outer end, slotted eye B place; Be provided with clothes-hook, extension spring, air pressure nail nail bar be sequentially connected, wherein clothes-hook is positioned at the outside of mounting A, and the nail bar of extension spring, air pressure nail is arranged in the inner chamber of sleeve pipe, and the ailhead of air pressure nail abuts on glue gasket.
The material of sleeve pipe described in the utility model is stainless steel.
Rainhat described in the utility model is made up of the plastic tube of U-shaped structure.
Plastic tube described in the utility model is PE pipe.
Described rainhat can prevent rainwater from entering in sleeve pipe.
Operation principle of the present utility model: under normal circumstances, extension spring is in normal state, and the ailhead of air pressure nail abuts on glue gasket, and form sealed environment, such steam just can not enter the inner chamber of sleeve pipe; When the air pressure in water tank reduces, under the effect of the pressure, the ailhead abutting in the air pressure nail on glue gasket is pulled away from glue gasket, and the inner chamber of such sleeve pipe is communicated with the inside of water tank, and then carrys out adjustable pressure.
The beneficial effects of the utility model: apparatus structure of the present utility model is simple, easy to operate, goes for different weather conditions, can be good at solving water tank and inhale flat problem.

Detailed description of the invention
By reference to the accompanying drawings the technical solution of the utility model is explained in detail.
As shown in Figure 1, a kind of preventing absorbing shrinkage safety valve of heat-preserving water tank for solar water heater, the utility model is characterised in that, the rainhat 2 comprising sleeve pipe 1 and be connected with sleeve pipe 1; Mounting A 3, mounting B 4 is respectively equipped with at the two ends of the inner chamber of sleeve pipe 1; Mounting A 3, mounting B 4 offer slotted eye A 5, slotted eye B 6 respectively, is provided with glue gasket 7 in outer end, slotted eye B 6 place; Be provided with clothes-hook 9, extension spring 8, air pressure nail 10 nail bar be sequentially connected, wherein clothes-hook 9 is positioned at the outside of mounting A 3, and the nail bar of extension spring 8, air pressure nail 10 is arranged in the inner chamber of sleeve pipe 1, and the ailhead of air pressure nail 10 abuts on glue gasket 7.
The material of sleeve pipe 1 described in the utility model is stainless steel.
Rainhat 2 described in the utility model is made up of the plastic tube of U-shaped structure.
Plastic tube described in the utility model is PE pipe.
Operation principle of the present utility model: under normal circumstances, extension spring 8 is in normal state, and the ailhead of air pressure nail 10 abuts on glue gasket 7, and form sealed environment, such steam just can not enter the inner chamber of sleeve pipe 1; When the air pressure in water tank reduces, under the effect of the pressure, the ailhead abutting in the air pressure nail 10 on glue gasket 7 is pulled away from glue gasket 7, and such inner chamber of sleeve pipe 1 is communicated with the inside of water tank, and then carrys out adjustable pressure.
Embodiment one
Preventing absorbing shrinkage safety valve is located at the top of attemperater.
Embodiment two
Preventing absorbing shrinkage safety valve is located at the sidewall of attemperater.
