Description
Technical field
It the utility model is related to a kind of stop valve, and in particular to a kind of forged steel check valve.
Background technology
Valve plays the important function of cut-out and throttling to the medium in the pipeline where it, and stop valve is used as one kind extremely
Important blocks class valve, and it is by applying moment of torsion to valve rod that it, which is sealed, and valve rod applies pressure to flap in the axial direction, made
Valve clack sealing surface is brought into close contact with sealing surface of seat, prevents medium along the slot leakage between sealing surface.Particle is carried in medium
When, easily sealing surface is caused to wear, common stop valve can not effectively compensate the sealing surface of abrasion, so as to cause
Stop valve can not dam.
Particle in medium can wear to the contact surface between hair bar and flap, between being had between the two after permanent
Gap, the medium of flowing is upward by flap, so that flap can not carry out choked flow；And can be produced between flap and valve rod should
Power, so as to cause to send out the damage of bar and flap.
Utility model content
Based on above mentioned problem, the utility model purpose be to provide it is a kind of being capable of wear-resistant, long lifespan, good seal performance
Forged steel check valve.
For problem above, there is provided following technical scheme：A kind of forged steel check valve, including bonnet, valve body, valve rod and
The flap being connected with valve rod, the flap include be connected with valve rod connecting portion, for stop medium flowed in valve body it is close
Envelope portion and the elastic portion being located between sealing and connecting portion, in a tubular form, the elastic portion is provided with and it for the elastic portion
The relatively logical helicla flute of endoporus, the flap are integral type, and the valve rod is in be detachably connected with flap, the valve rod and flap
Connecting place is provided with the spring for being used for reducing stress between flap and valve rod, and the spring is set on valve rod and is located at flap top
Portion.
In said structure, set helicla flute that flap can be made flexible.When being dammed, elastic flap can strengthen
Sealing.When containing particle in medium, particulate matter can cause to wear to the sealing surface of flap, so the flap being resilient can
It is compensated, so as to increase the life-span of valve and sealing.Flap body, which is resilient part, to be had high intensity and can carry
For more preferable wear-compensating.Spring can increase the sealing between flap and valve body, and sealing is closer.Valve rod is in flap can
Dismantling connection, when valve is closed, spring can slow down valve rod and bullet caused by pressure and Elastic valve clack compression is produced to flap
Power.
The utility model is further arranged to, and the sealing outer surface is welded with STL materials.
Using said structure, by increasing capacitance it is possible to increase the hardness and corrosion resistance of sealing surface.
The beneficial effects of the utility model：Compared to existing forged steel check valve, the utility model is simple in construction, installation side
Just, wear-resistant and long lifespan.When valve is closed, spring can slow down valve rod and pressure and Elastic valve clack compression are produced to flap
Caused elastic force, so as to prevent the abrasion and collision between flap and valve rod.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
A kind of forged steel check valve as shown in Figure 1 to Figure 2, including bonnet 1, valve body 2, valve rod 3 and be connected with valve rod 3
Flap 4, connecting portion 41 that the flap 4 includes being connected with valve rod 3, for stop sealing 42 that medium flows in valve body with
And the elastic portion 43 between sealing 42 and connecting portion 41 is located at, in a tubular form, the elastic portion 43 is provided with the elastic portion 43
Logical helicla flute 431 relative with its endoporus, the flap 4 are integral type, and the valve rod 3 is in be detachably connected with flap 4, described
Valve rod 3 and the connecting place of flap 4 are provided with the spring 5 for being used for reducing stress between flap 4 and valve rod 3, and the spring 5 is set in valve rod
On 3 and positioned at the top of flap 4.
In said structure, set helicla flute 431 that flap 4 can be made flexible.When being dammed, the elastic energy of flap 4
Enough strengthen sealing.When containing particle in medium, particulate matter can cause to wear to the sealing surface of flap 4, so be resilient
Flap 4 can compensate to it, so as to increase the life-span of valve and sealing.The body of flap 4 be resilient part have it is high-strength
Spend and more preferable wear-compensating can be provided.Spring 5 can increase the sealing between flap 4 and valve body 2, and sealing is closer.
Valve rod 3 is with flap 4 in being detachably connected, and when valve is closed, spring 5 can slow down valve rod 3 and produce pressure and elasticity to flap 4
Flap 4 compresses caused elastic force.
In the present embodiment, the outer surface of sealing 42 is welded with STL materials 421.Can increase sealing surface hardness and
Corrosion resistance.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification, above-mentioned vacation can also be made
If these improvement and modification also should be regarded as the scope of protection of the utility model.
