Abstract
The utility model provides a kind of check valve assembly structure, including valve body, and described valve body one end connects water inlet pipe, and the other end is connected with the interior annular magnetic steel bushing for setting magnet, and the annular magnetic steel bushing other end is connected with one end of support bar；The other end connection outlet pipe of the support bar；Spring is cased with outside the support bar, the spring one end connects the annular magnetic steel bushing, the other end connection outlet pipe of the spring；The check valve structure can be good at reaching sealing and the effect for preventing current from refunding using magnet and with spring, meanwhile, annular silica gel sheath can prevent that check valve assembly is stuck while avoiding tubes rows conductance from causing check-valves shake；Three packing rings, it is to avoid during valve body two ends decentractions or have during small burr in guide rail and the phenomenon of clamping stagnation occur.
Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of check valve assembly.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its main function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.
Existing check valve structure is complicated, and use for a long time can produce abrasion, when flow-rate ratio is less, sealing effectiveness
It is poor, change and repair it is very inconvenient, while also the rate of exchange are high for the cost of repair and replacement.
Utility model content
In order to solve, existing check valve structure is complicated, sealing effectiveness is bad, the problem of repair and replacement complexity cost is high, this reality
With a kind of check valve assembly structure simple in construction, changing convenient, good sealing effect of new offer.
To achieve these goals, the technical scheme of the utility model offer is：A kind of check valve assembly structure, including valve
Body, described valve body one end connects water inlet pipe, and the other end is connected with the interior annular magnetic steel bushing for setting magnet, and the annular magnetic steel bushing is another
End is connected with one end of support bar；The other end connection outlet pipe of the support bar；Spring, the bullet are cased with outside the support bar
Spring one end connects the annular magnetic steel bushing, the other end connection outlet pipe of the spring.Annular magnetic steel set with magnet is utilized
Magnet adsorbs the check valve assembly structure on water inlet pipe.It is firm and easy to operate simple.
As the preferred scheme of the utility model, the valve body is hour-glass in shape；The centre of the valve body is cased with projection
Annular silica gel sheath.The annular silica gel sheath can prevent that check valve assembly is stuck while avoiding tubes rows conductance from causing check-valves to tremble
It is dynamic.
Further, the valve body two ends are respectively equipped with first annular groove and the second annular groove, first annular groove
With in the second annular groove be provided with first annular packing ring and the second ring washer.
Further, the support bar, which is provided with the 3rd annular groove, the 3rd annular groove, is provided with the 3rd packing ring.
Pass through above three packing ring, it is to avoid clamping stagnation occur in guide rail during valve body two ends decentractions or when having small burr
Phenomenon.
The check valve structure utilizes the magnetic steel sleeve with magnet firmly to adsorb check valve assembly on water inlet pipe, only
When the hydraulic pressure of water inlet pipe reaches certain pressure, magnet could be promoted to depart from pipeline, the effect of water flowing is reached；And pass through spring
Increase the adsorption capacity of check valve assembly, reach better seal and the effect for preventing current from refunding.
The utility model is relative to the beneficial effect of prior art：The check valve structure utilizes magnet and can with spring
Sealing and the effect for preventing current from refunding are reached well, meanwhile, annular silica gel sheath can prevent check valve assembly stuck simultaneously
Tubes rows conductance is avoided to cause check-valves shake；Three packing rings, it is to avoid during the decentraction of valve body two ends or have and leading during small burr
There is the phenomenon of clamping stagnation in rail.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
Explanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each other
It can just be mutually combined.
As shown in figure 1, a kind of check valve assembly structure, including valve body 6, valve body 6 is provided with water inlet 1, water inlet 1 connect into
Water pipe, the other end is connected with the interior annular magnetic steel bushing 9 for setting magnet, and the other end of annular magnetic steel bushing 9 is connected with one end of support bar 10；
The other end connection outlet pipe of support bar 10；Spring (being not drawn into figure), spring one end connection annular magnetic are cased with outside support bar 10
Steel bushing 9, the other end connection outlet pipe of spring.Valve body 6 is provided with delivery port 4.
Before the non-water flowing of pipeline, the magnet in magnetic steel sleeve firmly adsorbs check valve assembly on water inlet pipe, and water pump is opened
Qi Hou, hydraulic pressure slowly increases, when the hydraulic pressure of water inlet pipe reaches certain pressure, and water pressure pushing magnet departs from pipeline；Now reach
To the effect of water flowing.
When water-carrying capacity is small, the position that spring rebounds check-valves before non-water flowing, magnet holds water inlet pipe, prevented
Current are refunded.
As preferred embodiment, valve body 6 is hour-glass in shape；The centre of valve body 6 is cased with raised annular silica gel sheath
5.The annular silica gel sheath can prevent that check valve assembly is stuck while avoiding tubes rows conductance from causing check-valves shake.
In addition, the two ends of valve body 6 are respectively equipped with the first annular annular groove 7 of groove 2 and second, first annular groove 2 and
The first annular ring washer 8 of packing ring 3 and second is provided with second ring groove 7.
Support bar 10 is provided with the 3rd annular groove 11, the 3rd annular groove 11 and is provided with the 3rd packing ring 12.By above-mentioned
Three packing rings, it is to avoid during valve body two ends decentractions or have during small burr in guide rail and the phenomenon of clamping stagnation occur.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within protection domain of the present utility model.
