Abstract
The utility model relates to a one-way valve for a metering pump. The one-way valve comprises a valve body, a valve seat, a valve core, a valve plate, a spring gland and a spring, wherein the valve seat is fixedly connected with the lower end of the valve body; the lower end of the valve core is connected with the valve seat through threads, and the upper end of the valve core is fixedly connected with the spring gland; the valve plate is arranged on the valve core in a sleeving manner and is arranged below the spring gland; one face of the valve plate is a flat face, and the other face of the valve plate is a spherical face and covers the opening of the valve seat; and the spring is sleeved on the valve core and is arranged between the spring gland and the valve plate. The one-way valve disclosed by the utility model is simple in structure, good in sealing effect and easy to detect.
Description
Technical field
The utility model relates to a kind of valve body, particularly a kind of one-way valve for metering pump.
Background technique
One-way valve claims again safety check or check valve, is used for the flow direction of control media, and medium can only be flowed towards a direction in pipeline.Rely on the formed pressure promotion of the medium valve plate of forward flow to move during one-way valve work, make valve open, and when medium stopped supplying with, valve plate resetted under self gravitation or spring-force driven dual, was valve closing.The sealing surface of some one-way valve valve plate is the plane now, and its sealing is not fine, and structure is comparatively complicated, and later period maintenance is inconvenient.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, applied widely and sealing effect and better is used for the one-way valve of metering pump.
The technological scheme that realizes the utility model purpose is: the utlity model has valve body, valve seat, spool, valve plate, spring capping and spring; The lower end of described valve seat and valve body is connected; The lower end of described spool is threaded with valve seat, and the upper end of spool is fixedly connected with spring capping; Described valve plate is slidably located on spool, and is arranged on the below of spring capping; Described valve plate is simultaneously the plane, and another side is sphere, and the side lid of its sphere is located at the oral area of valve seat; Described spring housing is located on spool, and is arranged between spring capping and valve plate.
Above-mentioned spring capping is provided with towards the one side of valve seat the groove that blocks spring; The plane of described valve plate is provided with the groove that blocks spring.
Above-mentioned spring capping is fixed on the upper end of spool by bolt and pad.
The wall of above-mentioned valve body bulges.
The utlity model has positive effect: (1) the utility model adopts the valve plate of spheric, and its sealing effect is better; (2) the utility model is simple in structure, overhauls very convenient.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utlity model has valve body 1, valve seat 2, spool 3, valve plate 4, spring capping 5 and spring 6; Described valve seat 2 is connected with the lower end of valve body 1; The lower end of described spool 3 is threaded with valve seat 2, and the upper end of spool 3 is fixedly connected with spring capping (5) by bolt and pad; Described valve plate 4 is slidably located on spool 3, and is arranged on the below of spring capping 5; Described valve plate 4 one sides are the plane, and another side is sphere, and the side lid of its sphere is located at the oral area of valve seat 2; Described spring 6 is set on spool (3), and is arranged between spring capping 5 and valve plate 4; Described spring capping 5 is provided with towards the one side of valve seat 2 groove that blocks spring 6; The plane of described valve plate 4 is provided with the groove that blocks spring 6; The wall of described valve body 1 bulges.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
