Description
Technical field
The emulsion pump field that the invention belongs to, more particularly, the present invention relates to a kind of liquid sucting valve of emulsion pump.
Background technique
Liquid sucting valve is the hydraulic element realizing imbibition in emulsion pump, and the throttling limit of prior art liquid sucting valve spool is straight flange, and this structure imbibition efficiency is low, easily produces bubble, and during fluid flow, impact noise is large, produces larger harm to valve body and working surface.
Summary of the invention
Problem to be solved by this invention is to provide working fluid bubble in a kind of minimizing liquid sucting valve spool, avoids because the impact of fluid flow is to the liquid sucting valve of the emulsion pump that spool works the mischief.
To achieve these goals, the technological scheme that the present invention takes is the liquid sucting valve of a kind of emulsion pump provided, comprise valve casing and put spool in the inner, valve casing is provided with liquid entering hole and liquid outlet, valve casing liquid outlet one end is provided with blind nut, and spool is socketed with spring on the coupling shaft of blind nut one end, described spool end is provided with multiple oil duct, described spool is positioned at liquid entering hole one end and is provided with throttling limit, and described throttling limit is arranged at described oil duct edge, and described throttling limit is set to arc.
Preferably, liquid entering hole and liquid outlet are that about 90 ° of angles are arranged.
Preferably, liquid outlet is positioned at blind nut off-axis side.
Preferably, spool is fitted away from liquid outlet side and valve casing.
Preferably, blind nut and valve casing are for removably connecting.
Adopt technological scheme of the present invention, the throttling limit straight flange of emulsion pump liquid sucting valve spool liquid entering hole one end is changed to arc-shaped side design, meet the characteristic of flow of fluid, essentially eliminate the bubble that liquid produces in flow process, reduce impact noise during fluid flow, reduce the harm of liquid stream to valve body and work, the setting of multiple oil duct, increase the flow area of valve pocket, prevent the defects such as oilhole burr from producing clamping stagnation to valve core movement; Filler opening is vertical with oil outlet to be arranged, and liquid outlet is positioned at blind nut off-axis side, facilitates spool to the control of working state; Spool is fitted away from liquid outlet side and valve casing, is convenient to sealing, prevents hydraulic fluid leak in valve body; Blind nut and valve casing are for removably connecting, for convenience detach during maintenance spool, open blind nut and can complete maintenance to valve inner.
