Description
Technical field
The utility model relates to a kind of sea water pump and uses outlet valve.
Background technique
Existing plunger pump comprises valve seat, valve bonnet, spool with the turnover water valve, is provided with spring in the valve bonnet and withstands spool, and valve seat is provided with paddle hole; Spool is similar to one flat plate and covers on the paddle hole of valve seat, and spool and valve seat are plane sealing structure, and its shortcoming is: sealing is poor; Moisture absorption is poor; Receive the influence of sordid working medium easily, promptly some impurity in the working medium possibly rest on and cause sealing surface not seal on the sealing surface, or the damage sealing surface; Thereby cause unstable working condition, shorten the working life of inlet valve; Operating noise is big, owing to be plane sealing structure, turnover water valve spool when opening or closing with valve seat Strike note greatly can take place.
The model utility content
The purpose of the utility model is to overcome the shortcoming of existing technology, provides a kind of good airproof performance, stable working state, the high sea water pump of precision to use outlet valve.
The purpose of the utility model realizes through following technological scheme: sea water pump is used outlet valve, and it comprises spring seat, spool, spring and valve seat, and described valve seat is provided with osculum; Spool comprises diversion column, conus portion and the columnar portion that connects successively; Spring housing is loaded on the columnar portion, and spool is arranged between spring seat and the spool, and spring one end presses on the spring seat; One end presses on the flat end face of conus portion of spool; The conical surface of conus portion presses on the osculum of valve seat, and diversion column is positioned at osculum, and the end of spring seat is provided with the water outlet through hole.
The inner chamber of described spring seat becomes stepped shape, comprises macroporous cavity and little vestibule, and the diameter of described macroporous cavity is greater than the maximum diameter of conus portion, and the diameter of described little vestibule is less than the maximum diameter of conus portion.
The sectional shape of described diversion column is a triangle, and leg-of-mutton facing mutually is provided with circular arc chamfering between the limit.
Described valve seat outer surface is provided with groove, is provided with the O RunddichtringO in the groove.
The utlity model has following advantage: the spool of the utility model is provided with conus portion, and the osculum of its conical surface and valve seat has formed linear sealing, does not receive the influence of impurity in the working medium; Good airproof performance, stable working state, precision is high; Long service life, the sound that sends when opening or closing is little; The utility model also is provided with diversion column, can form protection to conical surface, increases the service life.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
Like Fig. 1, shown in Figure 2, sea water pump is used outlet valve, and it comprises spring seat 1, spool 2, spring 3 and valve seat 4; Described valve seat 4 is provided with osculum 5, and spool 2 comprises diversion column 6, conus portion 7 and the columnar portion 8 that connects successively, and spring 3 is set on the columnar portion 8; Spool 2 is arranged between spring seat 1 and the spool 2; Spring 3 one ends press on the spring seat 1, and an end presses on the flat end face of conus portion 7 of spool 2, and the conical surface of conus portion 7 presses on the osculum 5 of valve seat 4; Diversion column 6 is positioned at osculum 5, and the end of spring seat 1 is provided with water outlet through hole 12.
The inner chamber of described spring seat 1 becomes stepped shape, comprises macroporous cavity 9 and little vestibule 10, and the diameter of described macroporous cavity 9 is greater than the maximum diameter of conus portion 7, and the diameter of described little vestibule 10 is less than the maximum diameter of conus portion 7.
The sectional shape of described diversion column 6 is a triangle, and leg-of-mutton facing mutually is provided with circular arc chamfering between the limit, and the diameter of the turning surface that diversion column 6 rotations form is slightly less than the diameter of osculum 5.
Described valve seat 4 outer surfaces are provided with groove, are provided with O RunddichtringO 11 in the groove.
The working procedure of the utility model is following: when the hydraulic pressure in the plunger bushing during greater than external pressure; Spool 2 is backed down by the seawater in the plunger bushing; The conical surface that is spool 2 separates and blow-by with the osculum 5 of valve seat 4, and water is through the exhalant canal of the gap entering pump housing of 4 of spool 2 and valve seats; When the hydraulic pressure in the plunger bushing during less than external pressure, spool 2 resets under spring 3 effects, and promptly spool 2 pastes mutually and seals with valve seat 4.
