Description
Technical field
The utility model is related to a kind of valve, and in particular to a kind of boxing formula solid forging lift 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.Lift check valve refers to that flap is vertical along valve body
The check-valves that center line is slided, lift check valve can be only installed on horizontal pipe, in high-pressure small-bore check-valves upper flap
Ball can be used.The valve body shapes of lift check valve are as stop valve（Can be general with stop valve）, therefore its fluid resistance
Force coefficient is larger.Its structure is similar to stop valve, and valve body and flap are identical with stop valve.Flap top and bonnet lower are machined with
Guide sleeve letter, flap is oriented to letter and can be freely lifted in valve small cup guiding letter, and when medium following current, flap is opened by medium thrust,
When medium arrheas, flap is leaned on to be dropped on valve seat from hanging down, and plays prevention medium counter flow.
Traditional lift check valve junction is typically using to welded type, to welded type easily because the temperature difference is big or pressure is high etc.
Factor and cause weld to leak or be broken, and be present concavo-convex irregular bending dimension in traditional flange disjunctor, forging
Curve deformation and the material intergranular structure adverse effect such as irregular are also easy to produce in journey.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of boxing formula solid forging lift check valve, main
The problem of check-valves leakage point is more are solved, the boxing formula solid forging lift check valve flange is connected and valve using boxing formula
Body by integral forming, it is not easy to occur because the factor such as the temperature difference is big or pressure is high and caused by weld leakage or the problem of be broken, and
In the absence of concavo-convex irregular bending dimension, curve deformation will not be produced in forging process and material intergranular structure is irregular etc. unfavorable
Influence.
The technical scheme that the utility model is used is：A kind of boxing formula solid forging lift check valve, including valve body, valve
Lid, flap, the water inlet and delivery port at valve body two ends, described bonnet lower end are connected with elastic component, described elastic component and valve
Valve is connected, and pad is provided between described valve body and the sealing surface of bonnet, and valve body is bolted with bonnet, described water outlet
Mouth is provided with outlet passage, and described outlet passage diameter is less than delivery port diameter and the setting that is tilted to the right, and described goes out current
Road left end is provided with horizontal valve seat, and described valve seat is provided with sealing gasket, and described valve body two ends circumference array is provided with method
Orchid, the connected mode of the flange and valve body is ring-like infiltration weldering or ring-like threaded weld.
Further, described valve body solid forging shaping.
Further, the angle of inclination of described outlet passage is 10 ° ~ 30 °.
Further, described elastic component is spring.
Further, described pad is soft graphite.
Further, described valve body surface is through hot spray painted zinc or aluminium-plated processing.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, boxing formula solid forging lifting non-return
Valve flange is molded using the connection of boxing formula and valve body, it is not easy to occur because the factor such as the temperature difference is big or pressure is high and caused by weld
The problem of place's leakage or fracture, and in the absence of concavo-convex irregular bending dimension, curve deformation will not be produced in forging process
And the material intergranular structure adverse effect such as irregular.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of boxing formula solid forging lift check valve, including valve body 1, bonnet 2, flap 3, the two ends of valve body 1
Water inlet 4 and delivery port 5, the described lower end of bonnet 2 are connected with elastic component 6, and described elastic component 6 is connected with flap 3, described
Valve body 1 and bonnet 2 sealing surface between be provided with pad 7, valve body 1 fixed by bolt 8 with bonnet 2, set on described delivery port 5
There is outlet passage 9, the described diameter of outlet passage 9 is less than the diameter of delivery port 5 and the setting that is tilted to the right, described outlet passage 9
Left end is provided with horizontal valve seat 10, and described valve seat 10 is provided with sealing gasket 11, the described two ends circumference array of valve body 1 and set
There is flange 12, the connected mode of the flange 12 and valve body 1 is welded or ring-like threaded weld for ring-like infiltration.The design with it is traditional whole
The advantage of body flange disjunctor forging is that forging technology is simple and cost is low, and more preferably, traditional flange disjunctor is because depositing for security performance
In concavo-convex irregular bending dimension, curve deformation is also easy to produce in forging process and the rough sledding such as material intergranular structure is irregular,
And the design realizes that straight line and forging technology material structure are uniform, curve deformation is few, intergranular structure is good, and and wire welding tech
It is combined, in the absence of concavo-convex irregular bending dimension, curve deformation will not be produced in forging process and material intergranular structure is irregular
Etc. adverse conditions.
It is preferred that, the described solid forging shaping of valve body 1.While integrally formed valve body 1 can increase mechanical strength
Valve leak point is reduced, sealing is improved.
It is preferred that, the angle of inclination of described outlet passage 9 is 10 ° ~ 30 °.The inclined design of outlet passage 9 contributes to completely
Water outlet, noresidue, and have certain function for preventing from flowing backwards.
It is preferred that, described elastic component 6 is spring, and described pad 7 is soft graphite.The described surface of valve body 1 is through heat
Spray zinc or aluminium-plated processing.Hot dip galvanizing process is extremely serious to water pollution, and environmental issue is protruded very much, so hot spray painted zinc, aluminium-plated
Technique is more and more extensive, can effectively reduce the pollution to environment.
The boxing formula solid forging lift check valve flange is molded using the connection of boxing formula and valve body, it is not easy to occurred
Because the factor such as the temperature difference is big or pressure is high and caused by weld leakage or the problem of be broken, and in the absence of concavo-convex irregular bending dimension
Degree, will not be produced in forging process curve deformation and material intergranular structure it is irregular wait adversely affect.
Every technical staff's notice：Although the utility model is described according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, and the repacking of any utilization inventive concept will all include this specially
In sharp scope of patent protection.
