Abstract
A kind of leak-tight seal circle of non-return valve.Two seal grooves are equipped with the basis of traditional rubber seal, so that rubber seal has multiple sealing surfaces with ball valve, multiple discharge orifices are equipped with the first seal groove on the seal groove of the water outlet of ball valve, when being leaked when the pressure of water inlet end is excessive if partially liq, it can first flow into the first seal groove, then spilt out in the first seal groove by the discharge orifice of water outlet, so not only prevent the leak fluid of water inlet end from entering from discharge orifice, also the liquid of leakage can be subjected to aerial drainage, and even if having part continue leakage when, it can be stored in the second seal groove, fluid seepage is prevented to outside valve, sealing effect is more preferable.
Description
Technical field
Valve seal field is the utility model is related to, particularly a kind of leak-tight seal circle of non-return valve.
Background technology
Since reform and opening-up, national economy is rapidly developed, and " scientific and technical innovation, autonomous innovation " has become today's society and sent out
The theme of exhibition, Chinese society develop to the direction of intensive, energy-saving and emission-reduction, low-carbon high-efficiency.In present many liquid
In transportation system, the control of valve is all be unable to do without, valve has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting or overflow
The functions such as pressure release, are required for using non-return valve to be connected at many aspects such as present oil tank, water pot, oil truck, water pipe
Logical or discharge, but if the sealing effect of valve is bad, valve easily has liquid to pass through sealing during closed
Enclose and leaked with the contact surface of ball valve, and the leakage of liquid slowly is had in much time using, corrode valve seat, cause more
Big leakage.Under scientific research personnel in China's same industry constantly makes great efforts and studies, although achieving certain progress,
Still unsolved technical problem is remained in practical application.
The content of the invention
A kind of deficiency the purpose of the utility model is to overcome more than, there is provided the leak-tight seal circle of non-return valve
.Two seal grooves are equipped with the basis of traditional rubber seal so that rubber seal has multiple with ball valve
Sealing surface, is equipped with multiple discharge orifices on the first seal groove on the seal groove of the water outlet of ball valve, when the pressure mistake of water inlet end
When being leaked when big if partially liq, it can first flow into the first seal groove, then by water outlet in the first seal groove
Discharge orifice is spilt out, and is so not only prevented the leak fluid of water inlet end from entering from discharge orifice, can also be let out the liquid of leakage
Stream, and even if having part continue leakage when, can be stored in the second seal groove, it is therefore prevented that close outside fluid seepage to valve
It is more preferable to seal effect.
Technical solution is used by the utility model solves its technical problem：Contain non-return valve spool, sealing ring, ring
Shape protrusion, the first seal groove, the second seal groove, sealing surface, discharge orifice, sealing ring is equipped with the top of non-return valve spool,
The sealing surface of sealing ring is equipped with three annular protrusions, is equipped with the first seal groove and the second seal groove between annular protrusion, and first
Right one side of something of seal groove is equipped with multiple discharge orifices, forms a kind of leak-tight seal circle of non-return valve.
The technical principle of the utility model is：Three annular protrusions, convex annular are equipped with the technology of traditional sealing ring
Two seal grooves are equipped between rising, multiple discharge orifices are equipped with the lower section of first seal groove on the right side of sealing ring, are pacified in sealing ring
During dress, if by sealing ring be installed on on the contact surface of ball valve, and by the side for having discharge orifice be installed on ball valve water outlet
Side, after good seal if in one end of water inlet because pressure is excessive to cause partially liq by the close of sealing ring and spool
During the gap leakage of front cover, the liquid leaked into can flow to aerial drainage at the discharge orifice on right side by the first seal groove, and even if having
When leakage is continued in part, it can also leak into the second seal groove, sealing effect is more preferable.
The beneficial effects of the utility model are：The leak-tight seal circle of a kind of non-return valve, by the first seal groove
Right side is equipped with discharge orifice, and the aerial drainage that the first seal groove flows to water outlet one end can be passed through in the fluid seepage of one end of water inlet
Hole, and second seal groove is additionally provided with above the first seal groove, further prevents fluid seepage to outside valve,
Sealing effect is more preferable, maintains drying and the health of environment.
Brief description of the drawings
Here is that the utility model is further illustrated with reference to attached drawing and example
Fig. 1 is：A kind of schematic diagram during the sealing of the leak-tight seal circle of non-return valve
Fig. 2 is：A kind of leak-tight seal circle of non-return valve looks up figure structure schematic representation
Fig. 3 is：A kind of close-up schematic view of the E of the leak-tight seal circle of non-return valve
In figure：1. non-return valve spool, 2. sealing rings, 3. annular protrusions, 4. first seal grooves, 5. second seal grooves,
6. sealing surface, 7. discharge orifices.
Embodiment
In Fig. 1,2,3：Contain non-return valve spool 1, sealing ring 2, annular protrusion 3, the sealing of the first seal groove 4, second
Groove 5, sealing surface 6, discharge orifice 7, are equipped with sealing ring 2 in the top of non-return valve spool 1, are equipped with the sealing surface 6 of sealing ring 2
Three annular protrusions 3, are equipped with the first seal groove 4 and the second seal groove 5 between annular protrusion 3, right one side of something of the first seal groove 4 is set
There are multiple discharge orifices 7, form a kind of leak-tight seal circle of non-return valve.
Three annular protrusions 3 are equipped with the technology of traditional sealing ring 2,4 He of the first seal groove is equipped between annular protrusion 3
Second seal groove 5, is equipped with multiple discharge orifices 7 in the lower section of first seal groove 4 on the right side of sealing ring 2, is installed in sealing ring 2
When, if by sealing ring 2 be installed on on the contact surface of ball valve, and by the side for having discharge orifice 7 be installed on ball valve water outlet
Side, after good seal if in one end of water inlet because pressure is excessive to cause partially liq by sealing ring 2 and spool
During the gap leakage of sealing surface 6, the liquid leaked into can flow to aerial drainage at the discharge orifice 7 on right side by the first seal groove 4, and i.e.
When making to have the part continue leakage, it can also leak into the second seal groove 5, sealing effect is more preferable.
