Abstract
A ball check valve mainly solves the problems that a ball body of an existing ball check valve is poor in wear resistance and impact resistance, and the ball check valve is poor in sealing performance. The ball check valve comprises an outlet valve body (1), an inlet valve body (2), a connecting piece (3) and an anti-corrosion ball body (4). The outlet valve body (1) and the inlet valve body (2) are connected through the connecting piece (3). The ball check valve is characterized in that the anti-corrosion ball body (4) is arranged inside the outlet valve body (1) and the inlet valve body (2), and can move between the outlet valve body (1) and the inlet valve body (2); a pressure resistant rubber sealing ring (5) is arranged on a side wall close to one side of the inlet valve body (2), and four guide ribs (6) which are evenly distributed along the axial direction are arranged on a side wall close to one side of the outlet valve body; and a pressing ring (7) is arranged between the four guide ribs (6) and the pressure resistant rubber sealing ring. The ball check valve effectively improves the wear resistance and impact resistance, and sealing performance of a sealing seat.
Description
Technical field
The utility model relates to a kind of safety check, is specifically related to a kind of ball check valve.
Background technique
Safety check is widely used in iron and steel, metallurgy, petroleum and chemical industry etc., and some have pump inlet/outlet position than deep-etching industry pipeline.Be mainly used to stop the pipeline medium to flow backwards, prevent releasing of the counter-rotating of pump and drive motor thereof and container inner medium.Although common steel safety check can guarantee aspect pressure-bearing, can not play the resistant to corrosive media effect; And water hammer is the constraint of safety check and whole pipeline one system life, and the ball check valve spheroid very easily makes the continuous friction texturizing of spheroid affect sealability and working life down washing away with the graininess medium in addition.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of ball check valve, existing ball check valve spheroid wear resistance and impact resistance is relatively poor and the ball check valve sealability is relatively poor problem have mainly been solved, wear resistance and the impact resistance of this ball check valve spheroid have improved, and the sealability of sealing seat has also improved.
The technological scheme that the utility model adopts is: a kind of ball check valve, comprise outlet valve body, import valve body, link, anticorrosion spheroid, the outlet valve body connects with inlet valve body and function link, anticorrosion spheroid is in import valve body and outlet valve body, and anticorrosion spheroid can be mobile between import valve body and outlet valve body; Sidewall near water inlet valve body one side is provided with the pressure-resistant rubber seal ring, and the sidewall of close water outlet one side is provided with four vertically equally distributed guiding ribs, is provided with trim ring between described guiding rib and the pressure-resistant rubber seal ring.
It is that flange connects that described outlet valve body is connected with the import valve body.
The beneficial effects of the utility model are: owing to taking technique scheme, Effective Raise the wear resistance of this ball check valve spheroid and the sealability of impact resistance and sealing seat.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-outlet valve body among the figure, 2-import valve body, 3-link, the anticorrosion spheroid of 4-, 5-pressure-resistant rubber seal ring, 6-guiding rib, 7-trim ring.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of ball check valve, comprise outlet valve body 1, import valve body 2, link 3, anticorrosion spheroid 4, outlet valve body 1 is connected with the import valve body and is connected with link 3, anticorrosion spheroid 4 is in import valve body 1 and outlet valve body 2, and anticorrosion spheroid 4 can be mobile between import valve body 1 and outlet valve body 2; Sidewall near water inlet valve body 2 one sides is provided with pressure-resistant rubber seal ring 5, and the sidewall of close water outlet one side is provided with four vertically equally distributed guiding ribs 6, is provided with trim ring 7 between described guiding rib 6 and the pressure-resistant rubber seal ring.Pressure-resistant rubber seal ring 5 adopts the forever low new type rubber of withstand voltage, abnormal rate, effectively reduces the water hammer in the pipeline, and has guaranteed to have obtained good sealing effect; Anticorrosion spheroid 4 is selected suitable anti-rot plastic according to the pipeline medium, and adds glass fiber material by certain formula rate, by the x radiation x effect, adopts the injection molding moulding, makes the wear resistance of spheroid and impact resistance obtain large increase; Guiding rib 6 length are reasonable, and when pump quit work, anticorrosion active force along with pressure medium was in time located along guiding rib 6, plays better seal action.
It all is that flange connects that described outlet valve body 1 is connected with the import valve body, can be connected with exterior part easily.
Claims (2)
1. ball check valve, comprise outlet valve body (1), import valve body (2), link (3), anticorrosion spheroid (4), outlet valve body (1) is connected 2 with the import valve body) connect with link (3), it is characterized in that: anticorrosion spheroid (4) is in import valve body (1) and outlet valve body (2), and anticorrosion spheroid (4) can be mobile between import valve body (1) and outlet valve body (2); Sidewall near water inlet valve body (2) one sides is provided with pressure-resistant rubber seal ring (5), sidewall near water outlet one side is provided with four vertically equally distributed guiding ribs (6), is provided with trim ring (7) between described guiding rib (6) and the pressure-resistant rubber seal ring.
2. ball check valve according to claim 1, it is characterized in that: described outlet valve body (1) is connected 2 with the import valve body) all be that flange connects.
