Abstract
The utility model provides a high-temperature check valve, comprising a valve body, a valve seat and a valve clack. The valve body comprises a left valve body and a right valve body; the left valve body and the right valve body are sealed and installed through a connecting member; the valve clack is a spherical framework; the outer ring of the framework is provided with a layer of rubber attached to the outer surface of the framework; the valve clack is installed on the right valve body through a valve rod; the inner wall of the right valve body is made into a groove-shaped cavity on the upper side of the valve clack; and the sealing plane of the valve seat and a center line of a pipeline form an angle of 300 degrees. The high-temperature check valve is applicable to horizontal pipelines and vertical pipelines; the valve clack is hidden and floated in the groove-shaped cavity in the inner wall of the right valve body after opening, thereby having the advantages of low flow resistance and light closing water hammer; and the valve is the spherical framework with improved elasticity and thus improves reliability of the valve.
Description
Technical field
The utility model relates to a kind of safety check, relates in particular to little, the resistant to elevated temperatures safety check of a kind of flow resistance.
Background technique
Safety check is widely used in the various medium pipelines.At present, the safety check on the market receives water hammering when non-return is closed, and flap is to contact firmly moment with valve seat; Flap directly impacts valve seat, and when causing closure of check ring, the vibrations noise is big; The trap serious wear, working life is short, can cause pipeline burst when serious, fracture; Flap is general in addition all opens and closes along gravitational direction, and flow resistance is big, wastes energy.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of the utility model provide a kind of flow resistance little, open and close high temperature sealing valve rapidly.
For realizing above-mentioned purpose, the technological scheme of the utility model is:
A kind of high temperature safety check, it comprises valve body, valve seat and flap, said valve body comprises left valve barrel and right valve barrel; Left valve barrel and right valve barrel are installed through the link sealing; Said flap is spherical skeleton, also has on the outer surface of one deck rubber attached to skeleton in the outer ring of skeleton, and flap is installed on the right valve barrel through valve rod; Process by the groove shaped cavity at the right valve barrel inwall of flap upside, become 30 between valve base sealing plane and the pipe centerline
0The angle.
Said link is a gasket seal, and said gasket seal is the round thin skin, is made up of surface layer and mesosphere, and surface layer is a polytetrafluoroethylene floor, and the mesosphere is that the sheet metal in flexible graphite plate and spurt or hole is formed.
Said sheet metal is positioned at the centre of sealing gasket lamella, and outwards is the symmetry properties structure with it.
At least more than one deck, the outer circumference in mesosphere is arranged with the metal bound edge to said flexible graphite plate.
The usefulness of technique scheme is:
The utility model is applicable to horizontal pipe and vertical pipe, and flap opens that the back is latent to float in the groove shaped cavity of right valve barrel inwall, have flow resistance little, close advantages such as water hammer is low; Flap is spherical skeleton, has improved the elasticity of pigtail, has improved the reliability of valve.
The utility model left valve barrel is connected through gasket seal with right valve barrel; Advantages such as the sealing gasket strength is high, the life-span is long, high temperature resistant; Overcome conventional check valves and met high temperature because of gasket seal and very easily damage, as caused the crack even the defective that causes safety check to leak such as burst apart.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is this novel schematic representation;
Fig. 2 is the schematic representation of this novel flap.
Embodiment
Embodiment:
Like Fig. 1, a kind of high temperature safety check shown in 2; It comprises valve body 1, valve seat 2 and flap 3; Valve body 1 comprises left valve barrel 4 and right valve barrel 5, and left valve barrel 4 is installed through link 6 sealings with right valve barrel 5, becomes a angle between the sealing plane of valve seat 2 and the pipe centerline; Make that reducing water hammer when flap is closed produces, a angle preferably adopts 30
0Flap 3 is spherical skeleton 8; Also have on the outer surface of one deck rubber attached to skeleton 8 in the outer ring of skeleton 8; Flap 3 is installed on the right valve barrel 5 through valve rod, can on valve rod, rotate, and processes by the groove shaped cavity at right valve barrel 5 inwalls of flap 3 upsides; Just in time latently after making flap 3 open float in the groove cavities 13 of right valve barrel, to reduce the flow resistance of 3 pairs of media of flap.Left valve barrel 4 is connected through link 6 with right valve barrel 5, and link 6 is a gasket seal, and said gasket seal is the round thin skin, is made up of surface layer and mesosphere, and surface layer is a polytetrafluoroethylene floor, and the mesosphere is that the sheet metal in flexible graphite plate and spurt or hole is formed.Sheet metal is positioned at the centre of sealing gasket lamella, and outwards is the symmetry properties structure with it.At least more than one deck, the outer circumference in mesosphere is arranged with the metal bound edge to flexible graphite plate.
Claims (4)
1. high temperature safety check, it is characterized in that: it comprises valve body, valve seat and flap, said valve body comprises left valve barrel and right valve barrel; Left valve barrel and right valve barrel are installed through the link sealing; Said flap is spherical skeleton, also has on the outer surface of one deck rubber attached to skeleton in the outer ring of skeleton, and flap is installed on the right valve barrel through valve rod; Process by the groove shaped cavity at the right valve barrel inwall of flap upside, become 30 between valve base sealing plane and the pipe centerline
0The angle.
2. a kind of high temperature safety check as claimed in claim 1; It is characterized in that: said link is a gasket seal, and said gasket seal is the round thin skin, is made up of surface layer and mesosphere; Surface layer is a polytetrafluoroethylene floor, and the mesosphere is that the sheet metal in flexible graphite plate and spurt or hole is formed.
