BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a valve having a guide for preventing water leakage, and more particularly, to a valve for preventing leakage of internal fluid by a guide for suppressing deformation of a sealing means, To a valve having a guide.

Among commonly used valves, valves of diaphragm type, such as Korean Patent Laid-Open No. 10-2015-0018795, "diaphragm and diaphragm valve ", are manufactured by casting or injection molding.

With the recent development of new plastics, injection molded valves have been used for valves that require corrosion resistance and heat resistance.

However, due to the characteristics of the material to be injection molded, there is a problem that heat is deformed separately from the thermal expansion rate, and internal fluid often flows out when deformation occurs.

As a result, there has been a problem that it can not be used at room temperature or low pressure so as to suppress the occurrence of deformation as much as possible.

In addition, although a plurality of O-rings are mainly used as a means for maintaining the sealing force, there is a problem that if the O-ring is deformed, the inner fluid must flow out.
