Description
Technical field
The utility model relates to water pump safety check technology, particularly relates to a kind of safety check with the anti-pull-off buckle structure of spool.
Background technique
Safety check is also known as check valve, one-way valve, one-way valve or check valve, and its effect is the function ensureing medium directional flow in pipeline and unlikely refluence.Can be used on the pipeline of the various operating modes such as oil, chemical industry, pharmacy, chemical fertilizer, power industry, Applicable media is water, oil product, steam, acid medium etc., is the valve controlling pipeline internal medium single flow direction, is used for preventing the medium in pipeline from flowing backwards.Open-shut device is opened voluntarily by media flow and strength or closes, and the valve flow backwards to prevent medium is on safety check; Safety check belongs to self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.
Safety check divides by structure, Lift check valve, Swing check valve and butterfly check valve three kinds can be divided into: Lift check valve can be divided into vertical and straight-through type two kinds, Swing check valve is divided into single-lobe formula, Double-disc type and multi-clove type three kinds, butterfly check valve is butterfly bivalve, butterfly single-lobe, above several safety check can be divided in Connecting format be threaded, Flange joint, welding be connected four kinds with wafer type.Safety check belongs to a kind of automatic valve, and its Main Function prevents medium from flowing backwards, prevents pump and drive motor reversion, and the releasing of vessel media, and the auxiliary system that also can be used for may being raised above system pressure to pressure wherein provides on the pipeline of supply.
This case is it is important to note that the spool opposing impact capacity of water pump safety check is poor, and after long-time Reusability, easily pull-off phenomenon is occurring, the stability of component is lower, cannot meet the usage requirement of high powered water pump; In addition, the effect controlling current is also poor.Therefore, for above aspect, need reasonably to improve prior art.
Model utility content
For above defect, the utility model provides a kind of spool to resist impact capacity enhancing, Reusability not pull-off, improve component stability, control the safety check with the anti-pull-off buckle structure of spool that water flow effects is better, can meet high powered water pump usage requirement, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of safety check with the anti-pull-off buckle structure of spool, comprise bottom valve valve body, described bottom valve valve inner has valve pocket, described bottom valve valve inner installs water pipe top cover, this water pipe top cover top arranges the buckle structure be made up of pin, draw-in groove, described buckle structure outer wall is offered a draw-in groove, a pin is set on water pipe top cover top;
Described water pipe top cover is through bottom valve valve body center, and the buckle structure at water pipe top cover top fixedly mounts water pipe tripod;
Water pipe tripod center hole interpolation water inlet pipe top cover top wherein and pin snaps in draw-in groove internal locking downwards.
Described bottom valve external surface sets up some circle outside threads, and in bottom valve valve body inner spool, cover has spring.
The beneficial effect with the safety check of the anti-pull-off buckle structure of spool described in the utility model is:
(1), when installing, check valve spool is assembled in valve body, then tripod is assembled on check valve spool, finally strut members is pressed into safety check notch, thus completes assembling; During work, safety check notch is added reality, stressed not yielding, makes the assembling of safety check and tripod more stable, not easily pull-off;
(2) by redesigning the structure of check valve spool, increase the pin feature of a water pipe top cover, check valve spool can be made to resist impact capacity greatly strengthen, can Reusability more than 100,000 times not pull-offs, also the instant impact of 100N can be resisted, improve the stability of component, particularly can meet the usage requirement of high powered water pump;
(3) complete component is mainly used on water pipe, by the setting of water pipe top cover spool, whole finished product can be made to use more of a specified duration, and the effect controlling current is more obvious than common.
