Abstract
An expanded water tank comprises a tank body consisting of an upper housing cover and a lower housing cover, wherein the upper housing cover is connected with an air valve, and the lower housing cover is provided with a pipe fitting, the end of the lower housing cover integrated with a bend hook on one end; the end of the upper housing cover is positioned in the bend hook of the lower housing cover, and a rubber film is sealed and arranged between the upper housing cover and the lower housing cover. Because that he end of the lower housing cover integrated with a bend hook on one end; the end of the upper housing cover is positioned in the bend hook of the lower housing cover, the utility model reduces the parts, components, and the cost; the integrated bend hook can avoid the gap of the jointing, thereby greatly improving the sealing capability and security of using.
Description
(1) technical field
The utility model relates to a kind of hot-water boiler equipment, particularly relates to a kind of expansion tank.
(2) background technology
Expansion tank comprises upper shell cover, lower cover, and upper and lower cap is by rubber diaphragm sealed connection.The patent No. is that 99241138.6 expansion tank discloses the technology that a kind of expansion tank up and down is tightly connected by clip, because clip need satisfy and block firm upper shell cover, lower cover and rubber membrane simultaneously, so the structure of clip has at least two parts to form, therefore the joint in various piece certainly exists the interface slit, thereby has influenced the sealing and the security of expansion tank.
(3) summary of the invention
The sealing that existing expansion tank exists is poor in order to solve, the shortcoming of poor stability, and the utility model provides a kind of good airproof performance, expansion tank that security is good.
The technical solution adopted in the utility model is for this reason:
