Envelope check-valves.
The present invention be employed technical scheme comprise that by its technical problem of solution：
75 degree of soft-sealing check valves, the valve body made including spheroidal graphite cast-iron, it is provided with fluid passage in valve body, in fluid passage
It is provided with the fluid apertures becoming 75 degree of angles with its axis, valve body is respectively equipped with valve cover hole and spiro pluging hole, valve above and below fluid apertures
Valve gap is provided with cap bore, spiro pluging hole is provided with plug screw, fluid apertures is provided with the flap that can close fluid apertures, described flap includes
The shape lobe core that be made of cast iron corresponding with fluid apertures and the gum cover being wrapped in lobe core periphery, the top one of described gum cover becomes
The chuck that type has extension arm and is located at extension arm end, described chuck be clamped to the side wall of described valve cover hole and valve gap it
Between, at the position of next-door neighbour's fluid apertures, described plug screw is bolted in plug screw in the hole, described lobe to described spiro pluging hole in telescopic manner
The bottom of core and gum cover is provided with the protuberance extending and abutting to plug screw top.
As preferred embodiment, the bottom of described valve gap is provided with the surface projection parallel with the side wall of valve cover hole, institute
State chuck to be clamped between the side wall of described valve cover hole and projection.
As preferred embodiment, the side wall of described valve cover hole is provided with the limited block at the edge being connected to chuck.
As preferred embodiment, described valve gap is provided with, with valve body junction, the gasket seal that nitrile rubber is made.
The invention has the beneficial effects as follows：The flap of the present invention is made up of gum cover and lobe core, lobe core intensity big it is ensured that close
Envelope effect；The overall offset of flap is realized by the deformation of gum cover, is active in one's movements, can automatically reset；During installation, flap passes through
Valve gap clamps, easy for installation, low manufacture cost；Plug screw is made to put in valve body by turn plug screw, can be by flap top
Open, thus realizing the effect opening it outside check-valves, complete function, test maintaining is convenient.
Brief description
It is further detailed with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the present invention.
Brief description：1- valve body, 2- valve gap, 3- plug screw, 4- flap, 5- fluid passage, 6- fluid apertures, 7- gasket seal, 8-
Limited block, 21- projection, 41- lobe core, 42- gum cover, 43- extension arm, 44- chuck, 45- protuberance.
Specific embodiment
With reference to Fig. 1, the check-valves of the present invention are mainly made up of valve body 1, valve gap 2, plug screw 3, flap 4.Valve body 1, valve gap 2 one
As made using spheroidal graphite cast-iron, plug screw 3 is typically made using rustless steel, to ensure bulk strength and hardness.
It is provided with fluid passage 5 in valve body 1, in fluid passage 5, is provided with the fluid apertures 6 becoming 75 degree of angles with its axis, flap 4 sets
In fluid apertures 6, fluid apertures 6 can be closed.Fluid apertures 6 becomes 75 degree of angles with the axis of fluid passage 5, and flap 4 can afford enough
Big Fluid pressure is it is ensured that operationally can be backed down.
Valve body 1 is respectively equipped with valve cover hole and spiro pluging hole above and below fluid apertures 6, and valve gap 2 is installed on valve cover hole, spiral shell
Plug 3 is installed on spiro pluging hole.At the position of next-door neighbour's fluid apertures 6, plug screw 3 is bolted in spiro pluging hole to spiro pluging hole in telescopic manner
Interior.During application, when turn plug screw 3, plug screw 3 can stretch in the hole.In order to ensure valve gap 2 load onto after sealing, valve gap 2
It is provided with the gasket seal 7 that nitrile rubber is made with valve body 1 junction.
Flap 4 includes the shape lobe core 41 that be made of cast iron corresponding with fluid apertures 6 and the glue being wrapped in lobe core 41 periphery
Set 42, integrally formed with extension arm 43 and the chuck 44 that is located at extension arm 43 end, chuck 44 is clamped for the top of gum cover 42
Between the side wall and valve gap 2 of valve cover hole.Preferably, the bottom of valve gap 2 is provided with convex parallel with the side wall of valve cover hole in surface
Post 21, chuck 44 is clamped between the side wall of valve cover hole and projection 21.In order to ensure the clamping effect of chuck 44, it is to avoid flap
4 integral shifts, the side wall of valve cover hole is provided with the limited block 8 at the edge being connected to chuck 44.Gum cover 42, extension arm 43 and folder
44 are integrally formed by rubber and make, after chuck 44 clamping, when the part of gum cover 42 and lobe core 41 composition is subject to Fluid pressure
When, extension arm 43 meeting stress deformation, so that flap 4 leaves fluid apertures 6 so that fluid apertures 6 is opened.When Fluid pressure disappearance or relatively
Hour, flap 4 can reset again, and fluid apertures 6 is closed.
The bottom of lobe core 41 and gum cover 42 is provided with the protuberance 45 extending and abutting to plug screw 3 top.When turn plug screw 3 makes
Plug screw 3 to valve body 1 be inserted into when, the top of plug screw 3 can exert a force to protuberance 45 so that flap 4 is backed down, thus realize outside beat
Open the effect of check-valves.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
