Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in figures 1 to 6, a kind of pressure reducing valve, including valve body 1 and core assembly, valve body 1 are cylindric, 1 outside wall surface of valve body
On open up there are two seal groove 10, sealing ring 4 is installed in seal groove 10.It is separated by partition 11 into water inside valve body 1
Chamber 101 and air chamber 102, intake antrum 101 penetrate through the upper end of valve body 1, and air chamber 102 penetrates through the lower end of valve body 1.Valve body 1
