Claims

[Scope of Claim for Utility Model Registration] (1) A through hole and upper and lower valve chambers are provided on the center axis of the valve body, the through holes are connected in a direction perpendicular to the upper valve chamber, and a protrusion is projected at the center of the upper surface. The prepared valve body is inserted into the lower valve chamber, and the upper elastic force of the spring presses it against the valve seat (closes the valve), and at the same time, the protrusion protrudes into the upper valve chamber so that it can freely slide up and down into the upper part of the upper valve chamber. The intermediate slider is provided in contact with the lower surface of the inserted intermediate slider, and the intermediate slider is slid up and down by an appropriate operating mechanism provided on the upper part and outside the valve body.
A high-pressure valve characterized by opening and closing the valve by moving the valve body up and down. (2) The operating mechanism is installed by forming a V-shaped cam on the upper surface of the intermediate slider, forming a triangular cam on the lower surface of the spindle connected to the handle, etc. outside the valve body, and fitting the triangular cam to the V-shaped cam. (valve closed state), and when the handle or spindle is rotated at a set angle (e.g. 90 degrees), the triangular cam rises to both upper sides of the V-shaped cam, causing the intermediate slider to slide down (open). 2. The high-pressure valve according to claim 1, wherein the high-pressure valve is provided to perform a high pressure valve. (3) The operating mechanism has a pin protruding from the upper surface of the intermediate slider, and a cam lever having a large diameter part (or convex part) and a small diameter part (or concave part) is attached to the upper part of the valve body at a set angle around the pivot. (For example, 90 degrees) Pivotally mounted to allow rotation up and down, and contact the pin tip of the intermediate slider with the small diameter part (or concave part) of the cam lever (valve closed state)
2. The high-pressure valve according to claim 1, wherein the large-diameter portion (or convex portion) presses down (opens) the pin-equipped intermediate slider and the valve body when the cam lever is rotated at a set angle.
