In use owing to diaphragm edge is by the pressure of push rod so that be stretched in the middle of diaphragm, diaphragm easily occurs tear to damage
Bad, cause relay failure, service life is short.
Summary of the invention
In order to solve the problems referred to above, the invention provides the electromagnetic valve location structure of a kind of anti-diaphragm tear, at product body
Under long-pending immovable premise, increase electromagnetic attraction, improve product electromagnetic performance.
The present invention is achieved by following technical solution.
A kind of anti-diaphragm tear electromagnetic valve location structure, including upper cover plate and lower cover and be arranged on upper cover plate with under
Valve body between cover plate, is provided with bracing frame, also sets between upper cover plate and lower cover between described upper cover plate and lower cover and valve body
There is push rod, be additionally provided with upper diaphragm and lower diaphragm between upper cover plate and lower cover and the valve body around described push rod, in described cover plate
The upper diaphragm installation place on surface is provided with diaphragm mounting groove and push rod locating slot, the upper diaphragm end end face of described push rod and its place
Spacing≤0.5mm between bottom push rod locating slot.
Further, the gap between bottom the end face of described push rod and the push rod locating slot at its place be 0.3～
0.5mm。
Further, the gap≤0.3mm bottom described diaphragm mounting groove and between upper diaphragm.
Further, the gap bottom described diaphragm mounting groove and between upper diaphragm is 0.1～0.3mm.
The invention has the beneficial effects as follows:
A kind of anti-diaphragm of the present invention tear electromagnetic valve location structure, by cover plate floor design shape with on
Diaphragm or the corresponding diaphragm mounting groove of lower diaphragm back side shape, and make push rod locating slot bottom surface and the push rod of cover inner surface
End clearance is maintained in less scope, makes diaphragm mounting groove bottom surface and film gap be maintained in less scope, reduces
The push rod compress variation to diaphragm edge, makes diaphragm preferably be supported in diaphragm mounting groove and protect, the most simultaneously
Affect the normal work of relay, it is ensured that diaphragm is operationally not damaged by, thus extends the service life of electromagnetic relay.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
In figure: 1-lower cover, 101-diaphragm mounting groove, 2-bracing frame, 3-upper diaphragm, 31-curvature portion, 4-push rod, 41-
Push rod end face, 5-valve body, diaphragm under 6-, 7-upper cover plate, 11-push rod locating slot, 12-bossing.
Detailed description of the invention
Further describe technical scheme below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in Figure 1 and Figure 2, the electromagnetic valve location structure of a kind of anti-diaphragm of the present invention tear, including upper cover plate 7
And lower cover 1 and the valve body 5 that is arranged between upper cover plate 7 and lower cover 1, described upper cover plate 7 and lower cover 1 and valve body 5 it
Between be provided with bracing frame 2, be additionally provided with push rod 4, the upper cover plate 7 around described push rod 4 and lower cover 1 between upper cover plate 7 and lower cover 1
And being additionally provided with upper diaphragm 3 and lower diaphragm 6 between valve body 5, upper diaphragm 3 installation place of described cover plate 1 inner surface is provided with diaphragm and installs
Between bottom groove 101 and push rod locating slot 11, the upper diaphragm 3 end end face of described push rod 4 and the push rod locating slot 11 at its place
Spacing≤0.5mm.
Gap between bottom the end face of described push rod 4 and the push rod locating slot 11 at its place is 0.3～0.5mm.
Gap≤0.3mm bottom described diaphragm mounting groove 101 and between upper diaphragm 3.
Gap bottom described diaphragm mounting groove 101 and between upper diaphragm 3 is 0.1～0.3mm.
Embodiment
Lower cover 1 is designed to relative with upper diaphragm 3 back side shape by the technical program with the shape of upper cover plate 7 inner surface
Should, and diaphragm mounting groove 101 and push rod locating slot 11 are set in the position that lower cover 1 and upper cover plate 7 are corresponding with upper diaphragm 3；
Meanwhile, to bottom the diaphragm mounting groove 101 of lower cover 1 and upper cover plate 7 and between upper diaphragm 3, less gap is set, to push rod
Bottom locating slot 11 and between push rod 4 end face, less gap is set, makes during the curvature portion stress of upper diaphragm 3, to obtain diaphragm peace
The support of tankage 101, during the marginal portion stress of upper diaphragm 3, curvature portion has bigger deformation space, will not be because of stress
Excessive and cause tired tear, make the marginal portion of upper diaphragm 3 will not damage because of the extruding by push rod 4.
During work, push rod 4 stress, the edge of upper diaphragm 3 is produced pressure, the marginal portion of upper diaphragm 3 deforms upon, on
The curvature portion of diaphragm 3 is to negative camber Direction distortion, along with the increase of push rod 4 stress, push rod end face 41 and push rod locating slot 11
Bottom contact, stop deformation, and the pressure between the bossing 12 of upper cover plate 7 or lower cover 1 at the edge pressurized of upper diaphragm 3
Power is controlled, and the marginal portion of upper diaphragm 3 is protected, and the curvature portion 31 in the middle of upper diaphragm 3 is protected simultaneously；When upper
During curvature portion stress in the middle of diaphragm 3, the outside curved surface Direction distortion of curvature portion 31, when deformation reaches upper diaphragm 3 and diaphragm
Spacing bottom mounting groove 101, fits bottom upper diaphragm 3 positive camber and diaphragm mounting groove 101, and upper diaphragm 3 stops deformation, upper film
Curvature portion 31 in the middle of sheet 3 is protected.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its objective is to allow person skilled in art's energy
Solution present disclosure much of that is also implemented according to this, can not limit the scope of the invention with this, all real according to this programme
Equivalents done by matter content or amendment, all should contain within the scope of the present invention.
