Claims

[Claims for Utility Model Registration] 1. It has an inlet flow path and an outlet flow path whose flow paths are curved by a partition wall provided inside, and is further arranged at a certain angle with respect to the axis of the inlet flow path. a stop valve type valve body having a hollow chamber located between the two flow paths and having an axis line defined by the flow path; an opening having a diameter reduced from the downstream side to the upstream side, a lid attached to the valve body, supported by the lid, having an axis that coincides with the axis of the opening, and extending in the axial direction. Spindle that can move forward and backward;
A cylinder that is integrally provided at the lower end of the spindle, is installed to be able to move forward and backward into the hollow chamber so as to communicate with the opening, and whose lower end sealing surface can come into contact with the valve seat of the opening. a valve body that is slidably fitted into a cylinder, has a through hole therein that communicates with the opening, is located on the same axis as the opening, and always forms an orifice between the valve body; A constant flow valve comprising: a spring disposed between the valve body and the cylinder for urging the valve body to move away from the opening. 2. The constant flow valve according to claim 1, wherein the hollow chamber is arranged at an angle to the inlet flow path. 3. The constant flow valve according to claim 1, wherein the hollow chamber is arranged perpendicularly to the inlet flow path. 4. The constant flow valve according to claim 1 of claims 1 to 3, wherein the spring is a metal spring coated with trifluorochloroethylene resin.
