Abstract
The utility model relates to a rolling friction cock valve, including a valve body, a cock body, a valve rod, a valve cover, a transmission device, a sealing member and an installing member; a small end of the cock body is fixedly connected with one end of the valve rod; the other end of the valve rod is fixedly connected with an output shaft of a transmission device; a cylindrical projection is arranged in the center of a big end of the cock body; a cylindrical aperture is arranged on the valve cover corresponding to the cylindrical projection; a round table top is arranged at the cylindrical aperture opening; a ball bearing is arranged in the round table top; and an inner aperture of the ball bearing is sheathed on the outside of the cylindrical projection of the cock body. The cock body and the valve cover are in the rolling connection so as to decrease the configuration power of the transmission device. The rolling friction cock valve has advantages of small opening-closing torque, small volume and low cost and is adapted to fluid medium pipeline valves in various fields.
Description
Technical field
The utility model relates to a kind of valve, specifically about a kind of stopcock.
Background technique
Stopcock generally comprises valve body, faucet body, valve rod, valve gap, transmission device, Sealing and assembling set, the small end of faucet body is fixedlyed connected with an end of valve rod, the other end of valve rod is fixedlyed connected with the transmission device output shaft, its major defect is between big end and the valve gap of faucet body friction plate to be set to be connected, sliding friction between faucet body and the friction plate in the valve opening and closing process, keying moment is big, and the torque of transmission device is big, makes that the valve volume is big, cost is high.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of rolling friction stopcock that moment is little, small product size is little, cost is low that opens and closes is provided.
The technical solution of the utility model comprises valve body, faucet body, valve rod, valve gap, transmission device, Sealing and assembling set, the small end of faucet body is fixedlyed connected with an end of valve rod, the other end of valve rod is fixedlyed connected with the output shaft of transmission device, the big end center that mainly is faucet body has cylindrical bump, on the corresponding valve gap of cylindrical bump, be shaped on cylindrical hole, the cylinder aperture is shaped on a round table surface, one ball bearing is set, the cylindrical bump outside of the endoporus suit faucet body of this ball bearing in the round table surface.
In above technological scheme, the cylindrical bump end face of faucet body is provided with position regulating device, and this controlling device is made up of adjustable lever in the valve gap screw and adjusting screw.
The utility model has the advantages that: the big end of faucet body rolls by ball bearing with the valve gap torque and is connected, and its keying moment is little, thereby has reduced the allocating power of transmission device, reduces small product size, reduces product cost.
