Abstract
The utility model discloses a check ball valve, which belongs to a complex functional valve. A check ball body is arranged at the center part of a valve body, a rotating axle is arranged at the inner part of the valve body at the upper part of the valve ball body, a handle is arranged at the top part of the valve body, and nuts are installed at the center part of the handle; a clipping spring is arranged at the inner part of the right side valve body of the check ball body, a hexangular cap is installed outside the valve body; the valve body at the left side of the check ball body and the valve cover are installed together, and a loose joint nut is installed at the other side of the valve cover. Compared with the prior art, the check ball valve of the utility model has the advantages that the design is reasonable, the volume is small, the function is strong, and the installation and the operation are convenient, etc., the checking and stopping functions are integrated into a valve body, not only the space is saved, but also the cost is reduced.
Description
Technical field
The utility model relates to a kind of complex function valve, specifically a kind of ball check valve.
Background technique
Realize non-return in traditional solar energy plant and by function by stop valve, the two combination realization of safety check, the structure of stop valve and the two combination of safety check exists that application structure is poor, the shortcoming of poor reliability, has influenced the normal use of solar energy plant.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and a kind of simple in structure, cost of production is low, volume is little, function is strong a kind of ball check valve is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the center portion of valve body is provided with the non-return spheroid, and the inside of non-return spheroid top valve body is provided with rotatingshaft, and the top of valve body is provided with handle, and the center portion of handle is equipped with nut; The inside of non-return spheroid right hand valve body is provided with jump ring, and valve body is equipped with hexagonal nuts outward; The valve body and the valve gap in non-return spheroid left side are installed together, and the opposite side of valve gap is equipped with the loose joint nut.
The both sides of described non-return spheroid are provided with seal ring; The installation joint of described valve body and valve gap is provided with O type circle one; The installation joint of valve gap and loose joint nut is provided with Steel Cable Baffle Ring and pad; Be provided with O type circle two in the valve body of described rotatingshaft top.
This valve has the function of safety check and stop valve, has realized the fluid injection washing function of solar energy plant, and its handle embodies difference in functionality at diverse location.When handle orientations was parallel with the valve body center line, this valve had the non-return effect, and its function is equivalent to safety check; When handle orientations was vertical with the valve body center line, this valve had by effect, and its function is equivalent to stop valve; When handle orientations and valve body center line angle at 45, all pipelines of this valve communicate, and are equivalent to threeway on the function.
A kind of ball check valve of the present utility model is compared with prior art, has characteristics such as reasonable in design, simple in structure, that volume is little, function is strong, and is easy to install, concentrates on the valve body with non-return with by function and has not only saved the space but also reduced cost.
