Abstract
The utility model discloses a non-return pipeline sealing device, which is arranged in pipe body. The device comprises mounting base and water bevel. The mounting base is convex, having grooves inside the base and sliding bush on the outside. There is spring between the base and sliding bush. On the upper end of sliding bush is sealing surface which is triangular pyramid or globoid. The sealing surface is nested in the water bevel. The device with aforementioned structure has advantages of simple structure, low cost, durability, good seal ability and so on.
Description
Technical field
The utility model relates to the check valve technical field, more particularly relates to the sealing valve unit that a kind of pipeline is used.
Background technique
Check valve belongs to the essential part of the daily living water of people, be used for closed conduit, prevent foul smell or liter waterborne etc., the check valve of prior art generally adopts spring Sealing and tube wall to fit and seals, as application number 01112545, the applying date is April 5 calendar year 2001, denomination of invention is the patent application of the spherical sealing element of the above-mentioned patent of spring type floor drain check valve, is pulled the hole and is formed by overcoat, interior cover, filter screen, spring housing, spring link, spring, spring seat, cushion rubber, rubber pad, flap, nut, special use.Above-mentioned patent structure complexity, the cost height, the increase of switching manipulation number of times of long duration, flap is easy to wear, causes leakage.
The model utility content
The purpose of this utility model is exactly to provide a kind of foul smell that prevents to rise good sealing effect, the anti-reverse seal arrangement of pipeline durable and simple in structure in order to solve above-mentioned deficiency.
The technical solution that the utility model adopts for the technical solution problem is as follows:
The anti-reverse seal arrangement of a kind of pipeline, be arranged in the body, comprise fixed base and Xia Shui inclined-plane, this fixed base outer cover is connected to sliding sleeve, and this fixed base is a convex, and the centre is provided with groove, be provided with spring between sliding sleeve and the fixed base groove, the sliding sleeve upper end is a sealing surface, and the sealing face is the triangle cone, and this triangle cone is linked in the Xia Shui inclined-plane.
Described sealing surface also can be spherical surface body, is linked in the Xia Shui inclined-plane.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
One, simple in structure, cost is low; Adopt the two cone fits sealing on the convex fixed base, need not special process, manufacturing is simple.
Two, durable, good sealing effect; Adopt form sealing with spring attached seal fit, being used for of two opposing forces of elastic force of its static pressure by water on the Sealing and spring finished the work, when the static pressure of top water during greater than the elastic force of spring, densification sealing under water, spring shrinks, Sealing separates with the Xia Shui inclined-plane, reaches the purpose of draining; When the static pressure of top water during less than the elastic force of spring, spring opens, and Sealing will be closed under the effect of elastic force, and taper or spherical sealing element and Xia Shui inclined-plane auto-stitching play sealing, suppress the effect of gas, liter waterborne.The sealing part can adopt the wearing and tearing of material such as rubber little, more durable.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Embodiment
By shown in Figure 1, the anti-reverse seal arrangement of a kind of pipeline, be arranged on body 1 inwall, comprise fixed base 2 and Xia Shui inclined-plane 3, this fixed base 2 is positioned at 32 bottoms, Xia Shui inclined-plane, outer cover is connected to sliding sleeve 4, this fixed base 2 is a convex, and the centre is provided with groove, is provided with spring 5 between sliding sleeve 4 and fixed base 2 grooves, sliding sleeve 4 upper ends are triangle cone 6 sealing surfaces, and this triangle cone 6 is linked in the Xia Shui inclined-plane 3.
Xia Shui inclined-plane 3 is fixed on body 1 inwall, because triangle cone 6 is connected by sliding sleeve 4 with spring 5, during anhydrous discharging, spring 5 opens, and triangle cone 6 and Xia Shui inclined-plane 3 push fits and fix; When the water discharging is arranged, press the pyrometric cone sealing surface under water, spring 5 shrinks, and triangle cone 6 is separated with Xia Shui inclined-plane 3, reaches the draining purpose.Triangle cone 6 can adopt rubber material, good sealing effect, long service life with Xia Shui inclined-plane 3.
The utility model also has another kind of mode of execution, and the sealing surface of described sliding sleeve upper end also can be spherical surface body, and promptly the cambered surface of spherical surface body and Xia Shui inclined-plane fit are realized sealing.
Claims (4)
1, the anti-reverse seal arrangement of a kind of pipeline, be included in the Xia Shui inclined-plane that is provided with in the body, it is characterized in that: be provided with a fixed base in bottom, Xia Shui inclined-plane, this fixed base top is socketed with sliding sleeve, be provided with spring between sliding sleeve and the fixed base, the sliding sleeve upper end is a sealing surface, and the sealing face is linked on the Xia Shui inclined-plane.
2, the anti-reverse seal arrangement of a kind of pipeline according to claim 1, it is characterized in that: described this fixed base is a convex, and the centre is provided with groove, and spring is arranged between sliding sleeve and the groove.
