Abstract
A fusiform straight-flow type valve belongs to a valve, in particular to a valve for conveying fluid. The fusiform straight-flow type valve comprises a valve body, a valve core and a valve seat, wherein the valve body is provided with a flow passage inner cavity, the valve core is arranged in the flow passage inner cavity, and the valve seat is mounted on the inlet end of the valve body through apad. The fusiform straight-flow type valve is characterized in that the flow passage inner cavity of the valve body is in a fusiform shape, the inlet shaft line and the outlet shaft line of the valvebody share the same straight line, and the valve core is provided with a fusiform head. The valve body flow passage of the valve body adopts a fusiform design, the whole flow passage has no turning, and meanwhile, a streamline valve core head portion which is matched with the fusiform flow passage of the valve body is designed, the resistance factor of the valve is greatly lowered, and the fluidized form of the fluid is stable, thereby improving the delivering efficiency, lowering energy consumption, and saving energy sources.
Description
(1) technical field:
Spindle direct current type valve belongs to a kind of valve, in particular for the valve of FLUID TRANSPORTATION.
(2) background technique:
Traditional straight-through type, direct current type valve (safety check, stop valve, modulating valve), its body cavity runner such as Fig. 8, shown in Figure 9, tangible 90 ° or 45 ° of turnings are arranged, its spool is to import and export on the axial direction reciprocating (be generally and move up and down) perpendicular to valve, Oblique Stop Valve then forms one 45 ° or 90 ° of angles, the resistance coefficient of valve is increased, and the fluidised form instability influences transfer efficiency.
(3) summary of the invention:
Problem to be solved in the utility model be exactly provide at above deficiency that a kind of resistance coefficient is little, fluid stable, direct current type valve simple in structure.Its technological scheme is as follows:
It comprises valve body, spool and valve seat, and valve body has the runner inner chamber, and spool is positioned at the runner inner chamber, and valve seat is installed in the entrance point of valve body by pad.Its key technology is that the runner inner chamber of valve body is spindle, and the import and export axis of valve body is a same straight line, and spool has the spindle head.
The advantage that compared with prior art the utlity model has is:
1, the valve flowing channel of valve has adopted the spindle design, and whole runner does not have any turning round, and has designed the streamline spool head that is complementary with valve body spindle runner simultaneously, the resistance coefficient of valve is reduced greatly, and fluid flow state is stable, thereby improves transfer efficiency, cut down the consumption of energy energy saving.
2, conversion of the present utility model bindiny mechanism, with the rotation of handwheel that valve rod obtained or cylinder output or import and export pumping on the axial direction perpendicular to valve and be converted to spool and the consistent left and right sides to-and-fro motion of valve import and export axial direction, realize valve body spindle runner and streamline spool header matching, the resistance coefficient of valve reduces greatly.
3, the utility model is simple in structure, saves manufacture cost.
