Description
Technical field：
The utility model is related to control valve technical field, and in particular to a kind of damping check valve.
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.The structure of existing check-valves is relatively simple, in reality
When border is used, frequently result in that sealing effectiveness is bad and cause to have backflow, the effect of non-return is poor, and in the mouth side of non-return
All it is metal material, when non-return mouth is opened a little or will closed, because water velocity is big, is frequently accompanied by larger make an uproar
Sound.The guidance quality of other existing check plate is poor, general only to set at one end with even lead, can lead after a long time use
Cause the rubber stopper of check plate fully to be contacted with non-return mouth, can also reduce the effect of non-return.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency that there is provided a kind of service life
Long, stability is good, and non-return effect is good, the low damping check valve of noise.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of damping check valve, it is characterised in that：Including valve body, fixed mount, guide pillar, check slide, spring, rubber stopper, lead
To plate and noise elimination packing ring, described valve body is provided at both ends with valve opening, and described fixed mount is fixedly installed in the stomidium of valve body one,
Described guide pillar is fixedly installed on fixed mount and positioned at the inside of valve body, and one end of described check slide is for guide pin bushing and slidably
Be set on guide pillar, the other end of check slide is tabular, described spring be set on guide pillar and positioned at fixed mount with
Between check slide, described rubber stopper be fixedly installed on check slide into a side of tabular and match somebody with somebody with avris in the valve opening of valve body
Close, described guide plate be fixedly installed on check slide into a side of tabular and be slidably disposed in the inside of valve opening, lead
The inner avris of plate is provided with water-flowing trough, described noise elimination packing ring is attached on the inner hole wall of valve opening and coordinated with guide plate.
Adpting flange is both provided with the outside of the two ends of described valve body.
Outside is axially provided with chute on described guide pillar, and the guide pin bushing inner side of described check slide is fixedly installed
There is sliding pin and positioned at the inside of chute.
One side of the tabular of described check slide is provided with T-slot, and the innermost insert of described rubber stopper is in T-slot
It is internal.
The beneficial effects of the utility model are：Service life of the present utility model is long, and stability is good, and non-return effect is good, makes an uproar
Sound is low.
Brief description of the drawings：
Fig. 1 is the utility model structural representation.
Embodiment：
In order that technological means, creation new feature, reached purpose and effect that the utility model is realized are easy to understand,
With reference to being specifically illustrating, the utility model is expanded on further.
As shown in figure 1, a kind of damping check valve, including valve body 1, fixed mount 2, guide pillar 3, check slide 4, spring 5, rubber stopper
6th, guide plate 7 and noise elimination packing ring 8, valve body 1 are provided at both ends with valve opening, and fixed mount 2 is fixedly installed in the stomidium of valve body 1 one, leads
Post 3 is fixedly installed on fixed mount 2 and positioned at the inside of valve body 1, and one end of check slide 4 is guide pin bushing and is slidably set on
On guide pillar 3, the other end of check slide 4 is tabular, and spring 5 is set on guide pillar 3 and is located between fixed mount 2 and check slide 4,
Rubber stopper 6 be fixedly installed on check slide 4 into a side of tabular and coordinate with avris in the valve opening of valve body 1, guide plate 7 is fixed
Be arranged on check slide 4 into a side of tabular and be slidably disposed in the inside of valve opening, the inner avris of guide plate 7 is set
There is water-flowing trough 8, noise elimination packing ring 8 is attached on the inner hole wall of valve opening and coordinated with guide plate 7.All set on the outside of the two ends of valve body 1
There is adpting flange.Outside is axially provided with the inside of chute 9, the guide pin bushing of check slide 4 and is fixedly installed sliding pin on guide pillar 3
10 and positioned at chute 9 inside.One side of the tabular of check slide 4 is provided with T-slot, and the innermost insert of rubber stopper 6 is in T-slot
Inside.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
