The utility model discloses an it is fixed that the valve clack passes through the cylindric lock, and it is fixed reliable, and is more nimble during the rotation, easily control, valve clack periphery cover has the gum cover, and it can more closely be laminated with the liquid hole, and the leakproofness obtains guaranteeing, setting up of gum cover epirelief circle makes the leakproofness obtain further increase.
Description
Technical field
This utility model relates to a kind of valve products, is specifically related to novel 45 degree of soft-sealing check valves。
Background technology
Check-valves is a kind of common valve products, and it primarily serves the effect preventing liquid from flowing backwards。Traditional flap in check-valves only passes through to be pressed on the valve gap at its top and is fixed, and the dimensional accuracy between flap with valve gap is coordinated requirement higher by this structure, and inconvenience controls, and damage easily occurs in the process of folding in flap。Additionally traditional check-valves there is also the shortcoming that sealing property is poor。
Utility model content
For this, this utility model provides a kind of flap to rotate easily-controllable, sealing novel 45 degree of soft-sealing check valves reliably flexibly。
This utility model be the technical scheme is that by its technical problem of solution
Novel 45 degree of soft-sealing check valves, including the valve body that spheroidal graphite cast-iron is made, fluid passage it is provided with in valve body, it is provided with in fluid passage and its axis fluid apertures in angle of 45 degrees, valve body is respectively equipped with valve gap and plug screw above and below fluid apertures, fluid apertures is provided with, towards the side of valve gap, the flap that can fluid apertures be closed, flap periphery is enclosed with the gum cover being made up of ethylene-propylene diene copolymer, the section of flap is ρ shape structure, its head is located at the lower position of valve gap one end, straight pin it is coated with in head, the two ends of straight pin are fixed on valve body, gum cover is provided with and the flange collar of fluid apertures form fit towards the surface of fluid apertures。
As preferred embodiment, the bottom of described valve gap is provided with the portion that steps down being inwardly recessed。
As preferred embodiment, described valve gap and valve body junction are provided with the gasket seal that nitrile rubber is made。
The beneficial effects of the utility model are: flap of the present utility model is fixed by straight pin, and it is fixing reliable, more flexible during rotation, it is easy to control；Flap periphery is cased with gum cover, and itself and fluid apertures can be fitted more closely, and sealing is guaranteed, and the setting of gum cover upper convex ring makes sealing be further increased。
Accompanying drawing explanation
It is further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model。
Accompanying drawing illustrates: 1-valve body, 2-valve gap, 3-plug screw, 4-flap, 5-fluid passage, 6-fluid apertures, 7-straight pin, 8-gum cover, 9-flange collar, and 10-steps down portion, 11-gasket seal。
Detailed description of the invention
Referring in particular to Fig. 1, novel 45 degree of soft-sealing check valves of the present utility model mainly include valve body 1, valve gap 2, plug screw 3 and flap 4。Valve body 1 and valve gap 2 utilize spheroidal graphite cast-iron to make, and its intensity and hardness are guaranteed。
It is provided with fluid passage 5 in valve body 1, is provided with in fluid passage 5 and its axis fluid apertures 6 in angle of 45 degrees。Valve gap 2 and plug screw 3 are respectively arranged on above and below fluid apertures 6。Flap 4 is located at the fluid apertures 6 side towards valve gap 2, and the global shape of flap 4 mates with fluid apertures 6, and its section is ρ shape structure, and its head is located at the lower position of valve gap 2 one end, is coated with straight pin 7 in head, and the two ends of straight pin 7 are fixed on valve body 1。Under the effect of straight pin 7, flap 4 can rotate, when turn to fit in fluid apertures 6 time, fluid apertures 6 can be closed。In order to ensure valve gap 2 load onto after sealing, valve gap 2 and valve body 1 junction are provided with the gasket seal 11 that nitrile rubber is made。
The main body of flap 4 of the present utility model is made up of spheroidal graphite cast-iron, and its periphery is enclosed with the gum cover 8 being made up of ethylene-propylene diene copolymer, and under the effect of gum cover 8, fluid apertures 6 can be realized soft seal by flap 4。It addition, for the sealing effectiveness being further ensured that flap 4, gum cover 8 is provided with and the flange collar 9 of fluid apertures 6 form fit towards the surface of fluid apertures 6。When fluid apertures 6 is closed by flap 4, flange collar 9 can compress the periphery of fluid apertures 6, it is ensured that has good sealing effectiveness。
Consider that check-valves flap 4 when normal liquid passes through can continue to be pressed towards the bottom place of valve gap 2, so that the rotational angle of flap 4 is bigger, the bottom of valve gap 2 is provided with the portion that steps down 10 being inwardly recessed, and this portion 10 that steps down can so that flap 4 can with bigger angular turn, and liquid flowing is more smooth and easy。
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations。All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
