High-pressure valve and high-pressure water gun

A high-pressure valve, comprises a valve body,

• wherein the valve body comprises a valve seat cavity, a valve rod cavity and an adjusting cavity;
• the valve rod cavity is arranged between the adjusting cavity and the valve seat cavity;
• the valve rod cavity is communicated with the valve seat cavity through a first communicating hole, and is communicated with the adjusting cavity through a second communicating hole;
• the valve body is also provided with a water inlet and a water outlet, wherein the water inlet is communicated with the valve seat cavity;
• and the water outlet is communicated with the valve rod cavity;
• the valve seat cavity is internally provided with a valve core and an elastic piece, wherein the elastic piece provides an acting force for the valve core to move towards the first communicating hole;
• a valve rod is arranged in the valve rod cavity, wherein two ends of the valve rod are respectively inserted into the first communicating hole and the second communicating hole;
• an adjusting assembly is arranged in the adjusting cavity;
• one end of the adjusting assembly is connected with the valve rod, and another end of the adjusting assembly extends to the outside of the valve body;
• the adjusting assembly comprises an adjusting head and an adjusting rod, wherein the adjusting head is arranged at one end of the adjusting rod close to the valve rod, a radial section of the adjusting head is larger than that of the adjusting rod;
• the adjusting head divides the adjusting cavity into a pressure-reducing cavity and a buffer cavity;
• the pressure-reducing cavity is positioned at one side of the buffer cavity far away from the valve rod cavity and is communicated with the water inlet or the water outlet;
• the buffer cavity is communicated with external environment.
