Abstract
The invention discloses a liquid sucking valve for an emulsion pump. The liquid sucking valve comprises a valve casing and a valve core arranged in the valve casing, wherein a liquid inlet and a liquid outlet are formed in the valve casing; a screw cap is arranged at one end of the liquid outlet of the valve casing; a spring is sleeved on a connecting shaft, which is close to one end of the screw cap, of the valve core; a throttling side is arranged at one end, which is positioned at the liquid inlet, of the valve core; the throttling side is arranged into an arch shape; and a plurality of oil ducts are arranged on the end surface of the valve core. Due to the adoption of the technical scheme provided by the invention, a straight side of the throttling side at one end of the liquid inlet of the valve core of the liquid sucking valve for the emulsion pump is changed into the arc side, and thus the characteristics of liquid flowing are met, bubbles generated by liquid in the flowing process are eliminated, the impact noise in the flowing process of liquid flow is reduced and the damage to the valve body and the work caused by the liquid flow is reduced.
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 of realizing imbibition in the emulsion pump, and the throttling limit of prior art liquid sucting valve spool is straight flange, and this structure imbibition efficient is low, easily produces bubble, and impact noise was large when liquid stream flowed, and valve body and working surface are produced larger harm.
Summary of the invention
Problem to be solved by this invention provides working fluid bubble in a kind of minimizing liquid sucting valve spool, avoids the liquid sucting valve of the emulsion pump that the impact of flowing because of liquid stream works the mischief to spool.
To achieve these goals, the technological scheme that the present invention takes is: the liquid sucting valve of a kind of emulsion pump that provides, comprise valve casing and the spool of putting in the inner, be provided with liquid entering hole and liquid outlet on the valve casing, valve casing liquid outlet one end is provided with blind nut, spool is socketed with spring near on the blind nut one end coupling shaft, and described spool is positioned at liquid entering hole one end and is provided with the throttling limit, and the throttling limit is set to arc.
Preferably, be provided with a plurality of oil ducts on the spool end.
Preferably, liquid entering hole and liquid outlet are the setting of about 90 ° of angles.
Preferably, liquid outlet is positioned at blind nut off-axis one side.
Preferably, spool is fitted away from liquid outlet one 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 made into to design for arc-shaped side, the characteristic that meets flow of fluid, elimination the bubble that in flow process, produces of liquid, reduce the impact noise when liquid stream flows, reduced the harm of liquid stream to valve body and work; The setting of a plurality of oil ducts increases the flow area of valve pocket, prevents that the defective 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 one side, makes things convenient for spool to the control of working state; Spool is fitted away from liquid outlet one side and valve casing, is convenient to sealing, prevents hydraulic fluid leak in the valve body; Blind nut and valve casing are for removably connecting, and be for convenience detach during the maintenance spool, opens blind nut and can finish maintenance to valve inner.
