First, the angle valve of the prior art does not have any device at the water outlet end, if the angle valve is installed at the front end of the toilet, when the back pressure at the downstream of the angle valve increases or the upstream pressure in the pipeline system decreases to generate reverse siphon, the pipeline will be subjected to negative pressure to generate reverse pressure, so that the toilet water is easy to flow back into the domestic drinking water from the pipeline, and the water safety and the health of users are affected. The utility model discloses angle valve with non return function is equipped with prevention reflux unit check valve subassembly inside the angle valve, and it can prevent effectively that closestool water from flowing back, protects user's water safety, and its simple structure thinks about ingeniously, and the function is showing, and is strong from the clearing ability, can bring very big benefit for the user.

The angle valve of second, traditional structure sets up this kind of structure only one-way transmission in inside very few, and the check valve is equipped with to few angle valve structure in addition, and the check valve of traditional structure is complicated, maintains the difficulty, and the user uses the impurity that a period check valve will be by aquatic to block up, influences user's normal use.

Third, the angle valve of the conventional structure is provided with a sealing structure on the housing, which is generally independent sealing rubber, and in a long-time use state, the sealing rubber is easy to lose efficacy, resulting in the water leakage around the check valve.

Fourth, the angle valve of traditional structure, go up casing and casing down and adopt mutual interference fit, need the workman to assemble two spare parts together when the ann changes, go up the casing and will produce not hard up or even the obscission with casing down after the user uses a period, lead to the inefficacy of angle valve check valve function.

Fifth, the angle valve of traditional structure, handle and case valve rod rely on the gear shaping cooperation, appear the phenomenon of skidding when can effectively avoiding the handle rotating, but because the gear shaping on the handle and the case valve rod on the gear shaping hardly guarantee processing technology's uniformity, after the handle was installed on the case like this, the problem of partial appearance can appear in the handle, influences the whole outward appearance of product.

Sixth, angle valve of traditional structure, handle and case assembly back generally all are directly fixed with the screw, use the certain period handle will produce the phenomenon of becoming flexible and probably falling with case subassembly, and the handle of using the screw fixation because the screw only has the locking function, uses the certain period handle also can appear becoming flexible and the potential danger that drops.
