Summary of the invention
The object of the invention is to provide in order to solve above-mentioned the deficiencies in the prior art a kind of simple in structure, realize a kind of novel Combined ball valve that cut-off and medium flow backwards.
To achieve these goals, a kind of novel Combined ball valve that the present invention is designed, comprise the ball valve body with the turnover mouth of pipe, spheroid, valve rod and handle, described spheroid, valve rod is installed in ball valve body, described valve rod one end and spheroid secure fit, the other end stretches out outside ball valve body and is connected with handle, it is characterized in that: the outlet spout of described ball valve body is provided with threeway body, the joint of the outlet of described threeway body and the inlet pipe mouth of ball valve body is provided with safety check, described safety check is by Boilor check valve seat, non-return valve core, check-valve cap and spring, described non-return valve core one end is fixedly connected with check-valve cap, the other end is placed in inlet pipe mouth place and is sealed and matched, between the port of described inlet pipe mouth and Boilor check valve seat, be provided with the Boilor check valve seat seal ring for Leakage prevention, described threeway body is also provided with medium and enters pipe, filter and escape cock, described medium enters pipe and is communicated with escape cock by filter, the outlet of escape cock and the import of safety check are connected, described filter comprises filter screen.
Preferably, described medium enters pipe mounting blocks and the retaining ring with aperture is installed, and described mounting blocks is Z-shaped, and Fixing shrink ring is on mounting blocks.
Preferably, described valve rod and the Placement of handle are that described handle one end is provided with two mounting holes, matching hole, U-shaped mounting rod and inner groovy, described valve rod port goes out to be provided with ring-type inner groovy, valve rod port is arranged in the matching hole of handle, U-shaped mounting rod intercalation is in mounting hole, and U-shaped mounting rod also passes ring-type inner groovy.
A kind of novel Combined ball valve that the present invention obtains, this ball valve is comprised of a plurality of different valves, can realize when flowing medium flows into medium and enters pipe and enter escape cock, in the middle of it, be provided with filter, the blockage problem that prevents that using process from occurring of filtering that can be to medium, then opens through escape cock, and flowing medium flows in safety check then, and having the control valve being communicated with safety check control unlatching or close, safety check is conducive to the phenomenon that prevents that medium from flowing backwards.
