Abstract
The invention relates to an ore pulp check valve, in particular to the check valve for a water diaphragm pump, which belongs to the technical field of water diaphragms. A slow opening and closing ball core check valve comprises an upper valve cover, a damping guiding cylinder, an upper valve body, a ball core, a valve seat and a lower valve body. The damping guiding cylinder is fixed on the upper valve cover through bolts; the upper valve cover is connected with the upper valve body through bolts; the upper valve body is arranged on the valve seat and is fixed with the lower valve body through bolts; the valve seat is arranged on the lower valve body; the ball core is arranged on the valve seat. The slow opening and closing ball core check valve has the technical scheme that an upper baffle of the existing check valve is omitted, and the cylinder is additionally arranged on the valve cover to form resistance to upward movement and downward movement of the ball core, so that the movement speed of the ball core is ensured to be slowed down, and vibration is eliminated.
Description
Technical field
The present invention relates to a kind of pulp check valve, especially water diaphragm pump safety check, belong to the technical field of water diaphragm pump.
Background technique
Ball core safety check is the most frequently used safety check of water diaphragm pump, and being valve seat below its structure ball core, is block above.When ball core is closed, often upwards hit block and hit valve seat downwards, all produce vibration.
Summary of the invention
For the above-mentioned defect of prior art, the object of the invention there is provided a kind of slow keying ball core safety check, ensures that ball core movement velocity slows down, eliminates vibration.
In order to achieve the above object, the invention provides following technological scheme:
A kind of slow ball core safety check that opens and closes comprises: bonnet, damping guide cylinder, upper valve body, ball core, valve seat, lower valve body, described damping guide cylinder is bolted on bonnet, described bonnet is connected with upper valve body by bolt, described upper valve body is arranged on valve seat, and fixed by bolt and lower valve body, described valve seat is arranged on lower valve body, and described ball core is arranged on valve seat.
The invention has the beneficial effects as follows: the overhead gage cancelling safety check in the past, provide a kind of brand-new ball core safety check, kinetic damping type guide mechanism, slow keying ball core safety check.When ball core works, above ball core, slurry is by the gap of ball core and cylinder to dirty, and ball core is moved upward formation resistance; Otherwise ball core falls, slurry, also falls to forming resistance to ball core to upper reaches by gap, ensures that ball core movement velocity slows down, eliminates vibration.
In order to further understand feature of the present invention and technology contents, refer to following detailed description for the present invention and accompanying drawing, but accompanying drawing only provides reference and explanation use, is not used for being limited the present invention.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by invention embodiment describe in detail, will make technological scheme of the present invention and other beneficial effect apparent.
Fig. 1 is that the present invention delays the structural representation opening and closing ball core safety check.
Embodiment
For further setting forth the technological means and effect thereof that the present invention takes, be described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
Refer to Fig. 1, a kind of slow ball core safety check that opens and closes comprises: bonnet 1, damping guide cylinder 2, upper valve body 3, ball core 4, valve seat 5, lower valve body 6, described damping guide cylinder 2 to be bolted on bonnet 1, described bonnet 1 is connected with upper valve body 3 by bolt, described upper valve body 3 is arranged on valve seat 5, and fixed by bolt and lower valve body 6, described valve seat 5 is arranged on lower valve body 6, and described ball core 4 is arranged on valve seat 5.
Working principle: when ore pulp flows from lower valve body 6 to upper valve body 3 direction, by the pressure jack-up ball core 4 of ore pulp, ball core 4 is in the process of motion, ball core 4 ore pulp above of damping guide cylinder 2, flowed downward by the gap of ball core 4 with damping guide cylinder 2, there is resistance in ball core 4 motion, therefore slowly moves.After flowing stops, ball core 4 falls by deadweight, and in dropping process, ore pulp is upwards flowed by ball core 4 damping guide cylinder 2 gap, also falls to forming resistance to ball core 4, ball core 4 is slowly fallen.Thus eliminate ball core 4 hit suddenly block with under pound valve seat and the vibration that produces.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
Claims (1)
1. a slow keying ball core safety check, it is characterized in that, comprise: bonnet, damping guide cylinder, upper valve body, ball core, valve seat, lower valve body, described damping guide cylinder is bolted on bonnet, described bonnet is connected with upper valve body by bolt, and described upper valve body is arranged on valve seat, and is fixed by bolt and lower valve body, described valve seat is arranged on lower valve body, and described ball core is arranged on valve seat.
