Abstract
The utility model discloses a rubber-clack check valve, which comprises a valve pin (1) and a valve clack capable of rotating around the valve pin (1), wherein the valve clack comprises an arbor (2) and a nylon reinforcement net (3) wrapping the arbor (2); rubber wraps the nylon reinforcement net (3); a steel wire rope (4) is paved in the nylon reinforcement net (3) along the arbor (2) and moves around the valve pin (1); and two ends of the steel wire rope (4) are fixedly connected with the arbor (2). The rubber-clack check valve has the advantages that the valve pin in the valve clack is connected with the arbor in a manner that the rubber wraps the steel wire rope arranged in the nylon reinforcement net instead of the conventional manner that the rubber wraps the nylon cloth, so that the valve clack of the rubber-clack check valve is difficult to stagger, the yield of the check valve is improved, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to rubber flap check valve, relates in particular to being connected of valve pin and arbor in the flap.
Background technique
Rubber flap check valve is a kind of valve commonly used, is mainly used in preventing that the fluid in the pipeline from flowing backwards, and causes the damage of equipment.Rubber flap check valve comprises valve body and is positioned at the encapsulate flap of valve body, at present, the encapsulate flap all is to connect like this: be connected by vulcanized rubber by the nylon strap between valve pin and the arbor, the shortcoming of this Placement is: on heavy caliber (DN400) rubber flap check valve, rubber clack is heavier, under normal circumstances, the rubber on nylon cloth and surface is pullled in the deadweight of arbor, in the larger area of summer in the winter temperature difference, rubber and nylon are furnished with large variation, and the time one is grown like this, and sealing surface dislocation will occur and causes leaking, reduce the performance of rubber flap check valve, affected up-to-standard rate and the working life of product.
The model utility content
Problem to be solved in the utility model is that the flap of rubber flap check valve is subject to ectocine and deforms, cause that sealing surface dislocation occurs and causes leaking, and a kind of rubber flap check valve that is connected between valve pin and the arbor of having strengthened is provided for this reason.
The technical solution adopted in the utility model is: a kind of rubber flap check valve, it comprises valve pin and the flap that rotates around valve pin, described flap comprises the nylon strengthening net of arbor and parcel arbor, nylon strengthening net outer cladding rubber, lay wire rope along arbor in the described nylon strengthening net, valve pin walked around by wire rope and two ends link to each other with arbor.
The improvement of such scheme is that described wire rope has two, on the arbor that is laid in side by side.
The utility model beneficial effect is: because the valve pin in the flap covers rubber outward with being connected by original nylon cloth of arbor, change into by wire rope outer cladding rubber is set in the nylon strengthening net, the flap of rubber flap check valve is difficult for dislocation like this, has improved the up-to-standard rate of safety check and the working life of product.
Description of drawings
Fig. 1 is the utility model schematic representation;
1 is valve pin among the figure, the 2nd, and arbor, the 3rd, nylon strengthening net, the 4th, wire rope.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises valve pin 1 and the flap that rotates around valve pin 1, described flap comprises the nylon strengthening net 3 of arbor 2 and parcel arbor 2, nylon strengthening net 3 outer cladding rubber, described nylon strengthening net 3 is interior to lay wire rope 4 along arbor 2, and it is affixed that wire rope 4 is walked around valve pin 1 and two ends and arbor 2.
In order further to increase join strength, described wire rope 4 has two, on the arbor 2 that is laid in side by side.
The utility model arranges wire rope in flap be one of the utility model mode of execution; so long as by at the nylon strengthening net 3 interior stiffening ribs that arrange; increase toughness and rigidity, prevent that the connection part distortion of flap all should belong within the protection domain of the present utility model.
Claims (2)
1. rubber flap check valve, it comprises valve pin (1) and the flap that rotates around valve pin (1), described flap comprises the nylon strengthening net (3) of arbor (2) and parcel arbor (2), nylon strengthening net (3) outer cladding rubber, it is characterized in that laying wire rope (4) along arbor (2) in the described nylon strengthening net (3), it is affixed that wire rope (4) is walked around valve pin (1) and two ends and arbor (2).
