Description
Technical field
The utility model relates to valve fields, more particularly to a kind of valve flap structure and safety valve.
Background technique
Safety valve is that opening and closing element is in normally off under by external force, is surpassed when the pressure medium in equipment or pipeline increases
When crossing specified value, by outside system discharge medium come to prevent pressure medium in pipeline or equipment be more than the particular usage valve of specified value
Door.Wherein the cooperation of valve base of safety valve and flap is the core of safety valve opening and closing.
For the safety valve under worst hot case, flap generallys use elastic sealing structure, by medium power and thermal deformation
Enhancing sealing.The primary structure of flap is as follows at present:
A surface groove is dug above valve clack sealing surface, as shown in Figure 1.When flap and high-temperature medium contact, medium exists
Inclined-plane groove location forms a downward medium power, enhances the sealing effect of flap.Further, since medium temperature is high, flap material
Material generates thermal deformation, but since sealing surface uses elastic construction, valve clack sealing surface and valve seat can be made to keep sealing well
Effect.
But due to digging a surface groove above valve clack sealing surface, the discharge of safety valve medium can thus be caused
It influences, while also reducing the structural strength of flap.Although therefore existing valve flap structure sealing performance is guaranteed well,
But the discharge capacity of safety valve can also be had some impact on simultaneously, especially in the case where pipe diameter is certain, the reduction of discharge capacity
The specification safety valve will be will lead to not to be available.Meanwhile in one timing of flap total thickness, digging a very long slot can also be reduced centainly
Intensity.Therefore, existing Elastic valve clack is optimized be very it is necessary to.
Summary of the invention
One purpose of the utility model is to provide a kind of valve flap structure, carries out on the basis of existing valve flap structure excellent
Change.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of valve flap structure, including flap main body, the flap main body have cooperated with valve seat the first face, with
The middle part in the second face that flap seat is attached, first face protrudes to form diversion division, and institute is located on first face
Surface groove is offered on the outside of the diversion division stated, what the first face formation described in the surface groove outside was sealed with valve seat
Sealing surface, on the inside of the surface groove, on the outside of the diversion division described in the first face there is one section of planarea.
Preferably, the planarea is generally aligned in the same plane with the sealing surface.
Preferably, the diversion division has inclined surface, and the inclined surface passes through transition face phase with the planarea
Connection.
It is further preferred that the transition face is cambered surface.
Preferably, it is provided with the interconnecting piece being connected with flap seat on second face, is opened up on the interconnecting piece
There is connecting hole.
It is further preferred that the interconnecting piece protrudes from second face.
It is further preferred that the connecting hole to open up direction consistent with the extending direction in the second face.
Preferably, the flap main body uses elastic material.
Another purpose of the utility model is to provide a kind of safety valve.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of safety valve, the safety valve include the valve flap structure.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
When the utility model is by digging surface groove, retains certain planarea and optimize the flow field of flap, flow resistance, enhancing peace
The discharge capacity of full valve, while also enhancing certain flap mechanical property.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of valve flap structure as shown in Figure 2, including the flap main body 1 using elastic material, flap main body 1 has and valve
The first face 10 that seat 2 is cooperated and the second face 11 that flap seat 3 is attached.Wherein:
The middle part in the first face 10 protrudes to form diversion division 12, and the outside on the first face 10 positioned at diversion division 12 offers inclined-plane
First face 10 of slot 13,13 outside of surface groove forms the sealing surface 100 being sealed with valve seat 2, in the present embodiment: surface groove
The first face 10 on the outside of 13 insides, diversion division 12 has one section of planarea 101, and planarea 101 and sealing surface 100 are located at same flat
Face.
In addition, diversion division 12 has inclined surface 120, inclined surface 120 is connected with planarea 101 by transition face 14, mistake
Crossing face 14 is preferably cambered surface.
Compared to the prior art as shown in Figure 1, medium all pours in surface groove by diversion division, although in inclined-plane slot position
It sets to form a downward medium power, the flow resistance for enhancing the sealing effect of flap, but increasing medium is unfavorable for the row of medium
It puts.Compared to the present embodiment as shown in Figure 2, medium is after the inclined surface of diversion division 12 120, transition face 14 along planarea 101
Flowing, certain media pour in surface groove 13, and certain media takes advantage of a situation continuation along streamlined flow, are changed by retaining certain plane
The medium flow field of safety valve.How much specific flow field will determine according to caliber size, pressure, structure etc. if capable of optimizing, structure design
When can by flow field analysis software determine.
It is provided with the interconnecting piece 110 being connected with flap seat 3 on second face 11, offers connecting hole on interconnecting piece 110
111.Interconnecting piece 110 protrudes from the second face 11, connecting hole 111 to open up direction consistent with the extending direction in the second face 11.
Compared to the prior art as shown in Figure 1, interconnecting piece is opened up on the second face of flap main body, is equivalent to and eliminates valve
The part-structure of valve main body reduces the intensity of flap main body to a certain extent.Compared to the present embodiment as shown in Figure 2, connection
Portion 110 protrudes from flap main body 1, increases the intensity of flap main body 1.
The valve flap structure can be applied on safety valve as shown in Figure 3.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
