Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a stop valve of valve rod structure, includes fixed station 1, is equipped with bearing 21 in the fixed station 1 middle part, and bearing 21 inner circle fixedly connected with valve rod 7 lets its valve rod 7 can rotate and can not the side-to-side swing, and bearing 21 outer lane fixedly connected with supporting shoe 5 supports carousel 6 in order to prevent supporting shoe 5 and fixed station 1 friction mutually and cause great damage.

The fixed station 1 both sides all fixedly connected with support column 2, support column 2 bottom surface fixedly connected with valve gap 3, channel 22 has been seted up to valve gap 3 top inboard, be equipped with packing 25 increase seal in the middle of the valve gap 3 top in order to prevent liquid from spilling, packing 25 rubber sleeve runs through packing 25 middle part, valve gap 3 bottom surface is equipped with valve body 23, valve gap 3 blocks up the water in valve body 23 and prevents liquid outflow, valve body 23 inboard top fixedly connected with fixed disk 13, the second notch 16 has all been seted up to fixed disk 13 left and right sides, first notch 12 has been seted up at fixed disk 13 middle part, second notch 16 all activity runs through there is dead lever 15, thereby dead lever 15 supports in fixed disk 13 both sides notch when closing the valve thereby move down sleeve 8 and close the valve, thereby dead lever 15 supports in fixed disk 13 both sides notch when opening the valve thereby move sleeve 8 upward, open the valve.

The dead lever 15 bottom surface fixedly connected with double-end valve clack 17, double-end valve clack 17 includes that first valve clack 26 and second valve clack 27 are made for rubber, thereby second valve clack 27 is because of setting up longer closing the valve and is preferentially blockked up the stopper mouth 18 of delivery port 20 side, when second valve clack 27 will block up, the less shorter first valve clack 26 of water pressure also blocks up the stopper mouth 18 of water inlet 19 side, carry out two sides shutoff leakproofness higher, double-end valve clack 17 top surface middle part fixedly connected with sleeve 8, when closing the valve, sleeve 8 activity runs through in first notch 12 and channel 22, all be equipped with a stopper mouth 18 about the bottom surface at the inboard middle part of valve body 23, water inlet 19 has been seted up on the right side of valve body 23, delivery port 20 has been seted up on the left side of valve body 23.

Four screws 14 are uniformly distributed on the valve cover 3, notches 9 are formed in the top of the inner side of the valve cover 3, a raised ring 10 is arranged at the bottom of the notches 9, a turntable 6 is fixedly connected to the top of a valve rod 7, a valve rod 7 is connected to the inner side of a sleeve 8 in a threaded mode, the valve rod 7 moves up and down to open and close a valve, a notch edge 11 is formed in the top of the valve body 23 in an integrated manner, a gasket 24 is placed on the top surface of the notch edge 11, and tightness is improved so that water can leak from the joint of the valve cover 3 and the valve body 23.

The connection port is connected with the water inlet 19 through a flange, and the other connection port is connected with the water outlet 20. When the valve is required to be closed, the valve rod 7 of the valve rod is rotated by rotating the rotary table 6, the fixed rod 15 is propped against the notches at two sides of the fixed disk 13 to move the sleeve 8 downwards, the double-end valve clack 17 is pressed downwards, the second valve clack 27 is longer, the longer second valve clack 27 preferentially blocks the plug 18 at the water outlet 20 side when the valve is closed, when the second valve clack 27 is to be blocked, the first valve clack 26 with smaller water pressure also blocks the plug 18 at the water inlet 19 side, and the fixed rod 15 is propped against the notches at two sides of the fixed disk 13 to move the sleeve 8 upwards to open the valve when the valve is opened.

To sum up, the double-end valve clack 17 is round platform and the wider internal narrow stopper mouth 18 of mouth bigger area of contact laminating setting makes it inseparabler thereby better play the effect of stopping, thereby dead lever 15 is through fixed disk 13 both sides second groove 16, thereby supports and prevents to rotate promotion double-end valve clack 17, fine avoiding valve rod 7 to rotate the distortion wearing and tearing and makes the valve damage that leads to.
