Abstract
A regulator valve contain: a housing, a left end cap, a right end cap, and a valve core assembly. The housing includes a left cavity, a right cavity, a valve hole, a left opening, and a right opening. The right cavity has an inlet, the valve hole has an outlet, and between the right cavity and the valve hole is defined a seat portion, the seat portion has an inwardly conical fence, a diameter of which decreases from the right cavity to the valve hole. The left end cap is connected with and closes the left opening. The right end cap is coupled with and closes the right opening. The valve core assembly is inserted through the valve hole and includes a piston portion and a closing portion.
Claims6
A regulator valve comprising
- a housing including a left cavity, a right cavity communicating with the left cavity, a valve hole defined between and communicating with the left cavity and the right cavity, a left opening formed on a left side of the housing, and a right opening arranged on a right side of the housing;
- the right cavity having an inlet defined on a peripheral wall of the right cavity;
- the valve hole having an outlet formed on a peripheral wall of the valve hole;
- between the right cavity and the valve hole being defined a seat portion, and the seat portion having an inwardly conical fence, a diameter of the inwardly conical fence decreases from the right cavity to the valve hole;
- a left end cap connected with and closing the left opening of the housing;
- a right end cap coupled with and closing the right opening of the housing;
- a valve core assembly inserted through the valve hole of the housing and including a piston portion formed on a left side of the valve core assembly and limited to slide in the left cavity of the housing and including a closing portion arranged on a right side of the valve core assembly, such that the closing portion contacts with the inwardly conical fence of the housing or a flowing slit is defined between the closing portion and the inwardly conical fence of the housing, and the valve core assembly slides in response to a pressure change acting on the piston portion to change a width of the flowing slit, thus controlling water pressure and water flow from the inlet to the outlet;
- wherein a first half taper angle θ1 of the inwardly conical fence of the seat portion relative to the seat portion is within 40 to 50 degrees;
- the closing portion is located at a connecting area of a first conical face and a second conical face, a second half taper angle θ2 of the first conical face relative to the right cavity is 4 to 9 degrees;
- a third half taper angle θ3 of the second conical face relative to the valve hole is 3 to 13 degrees more than the first half taper angle of the inwardly conical fence of the seat portion.
