Description

Mounting structure of vacuum breaker Technical Field The present utility model relates to a mounting structure of a vacuum breaker. Background The vacuum breaker is mainly used for preventing siphon backflow, and when a pipeline system (particularly a liquid conveying system) suddenly stops pumping, a valve is quickly closed, drainage and the like to cause downstream pressure suddenly drop, upstream liquid can be sucked back due to gravity or pressure difference (siphon effect). The vacuum breaker can rapidly introduce air, break vacuum, prevent liquid from being sucked back, and protect water source from pollution. The electromagnetic valve used for the intelligent closestool is generally provided with a vacuum breaker, and the vacuum breaker on the electromagnetic valve is troublesome to install, because the vacuum breaker needs to be installed in a narrow passage entirely, and the vacuum breaker needs to be improved. Disclosure of Invention The utility model aims to overcome the problems in the prior art, and designs a mounting structure of a vacuum breaker, which is convenient to mount. The mounting structure of the vacuum breaker comprises a valve body and the vacuum breaker, wherein the valve body is provided with a water inlet and two water outlets, the vacuum breaker comprises a body, the body is provided with two downwards extending sleeves, the sleeves are tightly attached to the top of the water outlets to form a seal, a valve core is arranged in each sleeve, the body is provided with a cavity communicated with air, and the valve core isolates the channel from the water outlets. During installation, the valve core is installed in the sleeve, then the body is placed on the top of the valve body, and the two sleeves are inserted into the water outlet, so that the installation is completed. The structure is simple and convenient to install by directly inserting the vacuum breaker to the valve body after the vacuum breaker is installed outside. As a preferred embodiment of the utility model, the circumference of the sleeve is further provided with a guide bar. The guide rod is used for guiding the vacuum breaker to be inserted into the water outlet. As a preferred embodiment of the utility model, the top of the water outlet is provided with a through hole, and the water outlet further comprises a fixing buckle, wherein two ends of the fixing buckle are provided with inserting rods, the inserting rods are inserted into the through holes, and the inserting rods press the top of the sleeve. The inserted link blocks the top of the sleeve and prevents the sleeve from sliding out of the water outlet. As a preferable implementation mode of the utility model, a downward baffle plate is arranged on the body, a jack is arranged on the baffle plate, a socket is arranged on the valve body, two fixing rods are arranged on the fixing buckle, hook parts are arranged at the end parts of the fixing rods, the fixing rods penetrate through the socket and the jack, and the hook parts are buckled on the jack. The plunger is prevented from sliding out of the socket. As a preferred embodiment of the present utility model, a detachable upper cover is provided on the cavity. As a preferred implementation mode of the utility model, the top of the cavity is provided with a clamping block protruding upwards, the end part of the clamping block is provided with an outward barb, the upper cover is provided with a clamping groove for the clamping block to be inserted into, and the barb buckles the clamping groove. Compared with the prior art, the valve has the beneficial effects that during installation, the valve core is firstly installed in the sleeve, then the body is placed on the top of the valve body, and the two sleeves are inserted into the water outlet, so that the installation is completed. The structure is simple and convenient to install by directly inserting the vacuum breaker to the valve body after the vacuum breaker is installed outside.
