The top socket of valve body is provided with threading nut, and the inner cavity top of the valve body is provided with Packing seat, and the Packing seat is described to fill out
It is provided with gasket at the top of backing strap, disk spring is provided at the top of the gasket, the body top is provided with gland, and sets
Packing seat, gasket, disk spring, gland are sequentially passed through in one end of the valve rod of body cavity, is provided at the top of the valve rod
Handle, the left handle are provided through handle pin, and holding screw, the bottom of the valve rod are provided on the right side of the handle pin
Portion is provided with valve point.
Preferably, the Packing seat inner cavity is respectively arranged with filler and filler two, and filler two is arranged at the top of filler.
Preferably, the bottom of the valve rod is provided with spherical protrusions, and the top of valve point passes through the groove and ball that match
Shape convex block is connected with valve handle activity.
Preferably, it is provided with external screw thread at the top of the valve rod, and the top of valve rod passes through the external screw thread and spiral shell that match
Pit is flexibly connected with handle.
Preferably, bottom is both provided with card slot at left and right sides of the inner wall of the gland, and the gland passes through the card that matches
Slot is flexibly connected valve body with fixture block.
Compared with prior art, the beneficial effects of the invention are as follows：
The disc spring loaded packing live valve prong valve, it is simple in structure, it is easy for installation should, the structure above the gasket on filler top,
Increase butterfly spring to compensate automatically after filler is worn, avoid therefore causing to leak, valve point is the work of special processing
Valve point, when installation, only need valve point being sleeved on the bulb of valve rod head, and when use can preferably realize sealing, and the needle-valve is compared to together
The class high life, low torque, and process and be more convenient, sealing effect is more preferable.
