Technical Field
The utility model relates to a technical field of vacuum machine especially relates to a novel check valve structure.
Background
The check valve is a valve which automatically opens and closes a valve flap by the flow of a medium and is used for preventing the medium from flowing backwards, and is also called as a check valve, a one-way valve, a reverse flow valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a novel check valve structure, simple structure, easy dismounting, application scope is wide.
In order to solve the technical problem, the utility model discloses a technical scheme be: a novel check valve structure comprising: penetrate material axle center, go into the feed cylinder, inlay and adorn the case in going into the feed cylinder front end and follow penetrate the discharging channel that material axle center axial set up, discharging channel's rear end is provided with the blown down tank, the blown down tank with form the die cavity that is used for placing check ball valve between the case, the axial is provided with the pan feeding passageway in the pan feeding section of thick bamboo, the interpolation of pan feeding passageway is equipped with the pan feeding screw rod, the pan feeding screw rod be used for with the sizing material propelling movement in the pan feeding passageway extremely the die cavity.
In a preferred embodiment of the present invention, the contact surface between the valve core and the check ball valve is a spherical surface.
In a preferred embodiment of the present invention, the outer diameter of the check ball valve is larger than the inner diameter of the feeding channel.
In a preferred embodiment of the present invention, the contact surface of the discharge chute and the check ball valve is an inwardly concave arc structure.
In a preferred embodiment of the present invention, the inner diameter of the discharge chute is larger than the outer diameter of the check ball valve.
In a preferred embodiment of the present invention, the axis of the material inlet channel and the axis of the material outlet channel are collinear.
In a preferred embodiment of the present invention, the injection shaft is fixedly connected to the feeding cylinder by a fastener.
The utility model has the advantages that: simple structure, preparation is convenient and with low costs, and check ball valve installs in the die cavity between blown down tank and case for the dismouting is convenient and fast more, and application scope is wide.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a sectional view of a novel check valve structure of the present invention;
fig. 2 is a terminal surface view of the discharge passage with check valve structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a novel check valve structure, including: penetrate material axle center 1, pan feeding section of thick bamboo 2, inlay the case 3 of adorning in the feed cylinder front end and along penetrating the discharging channel 4 that material axle center axial set up, penetrate material axle center and pass through fastener fixed connection with the pan feeding section of thick bamboo, discharging channel's rear end is provided with blown down tank 5, blown down tank with form the die cavity 7 that is used for placing check ball valve 6 between the case, axial is provided with pan feeding passageway 8 in the pan feeding section of thick bamboo, the interpolation of pan feeding passageway is equipped with pan feeding screw rod 9, the pan feeding screw rod is used for with the sizing material propelling movement in the pan feeding passageway extremely the die cavity.
Specifically, the contact surface of the valve core 3 and the check ball valve 6 is a spherical surface, the outer diameter of the check ball valve is larger than the inner diameter of the feeding channel, further, the contact surface of the discharge chute 5 and the check ball valve 6 is an inwardly concave arc surface structure, the inner diameter of the discharge chute is larger than the outer diameter of the check ball valve, and the axes of the feeding channel and the discharge channel are collinear.
During specific operation, the feeding screw rotates to extrude the sizing material into the cavity from the feeding channel, the non-return ball valve moves towards the discharging groove under the pushing of the sizing material, and the sizing material in the cavity can smoothly flow out of the discharging channel due to the fact that the inner diameter of the discharging groove is larger than the outer diameter of the non-return ball valve; and when penetrating the material when check ball valve is returned to the ball face department of case by the sizing material compression that has got into, because check ball valve's external diameter is greater than the size of the internal diameter of pan feeding passageway, the pan feeding passageway can be plugged up to check ball valve to prevent the adverse current of sizing material, compare current check valve structure, the utility model discloses a check ball valve structure adopts be general standard spare, and is with low costs, and convenient assembling still possesses out gluey fast advantage.
The utility model relates to a novel check valve structure's beneficial effect is: simple structure, preparation is convenient and with low costs, and check ball valve installs in the die cavity between blown down tank and case for the dismouting is convenient and fast more, and application scope is wide.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
