Description
Technical field
The utility model is related to inflation film manufacturing machine pressure type relief valve, belongs to plastic film production equipment technical field.
Background technology
PVC film main component is polyvinyl chloride, separately has addition other compositions to strengthen its heat resistance, toughness, ductility
Deng.The superiors of this skin covering of the surface are paints, and middle main component is polyvinyl chloride, and orlop is back of the body coating adhesive.It is to work as
It is modern it is deep in the world liked, a kind of rather popular and synthetic material for being also widely used.The global usage amount of PVC film exists
Second is in various synthetic materials.In the material that can produce three-dimensional table facial mask, PVC is most suitable material.PVC film
Production craft step generally include：Raw material → kneading → cold mixing and → extrusion-blown modling → PVC glass paper-based membrane → antistatic, heat
Seal coating processing → cutting → inspection → packaging → finished product.Inflation film manufacturing machine, blown film would generally be used in PVC film production process
Had higher requirements during machine blown film for blast, high-quality PVC film depends on constant blast.But existing blown film
Usually occur the too high phenomenon of blast in machine, therefore design a kind of relief valve pressure release is carried out when blast is too high and just seem to closing weight
Will.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art that there is provided inflation film manufacturing machine pressure type relief valve.
To achieve these goals, the utility model is inflation film manufacturing machine pressure type relief valve, includes the body of tubular, described
It is provided with the left of body on the outside of transversely movable end socket, end socket and is provided with one-way pressure valve, the right side of the body, which is opened, is set
Put so as to enabling air to enter body interior, the body interior be provided with slip ring, the periphery wall of the slip ring with it is described
The madial wall sealing of body is set and the slip ring can horizontally slip in the body；One sealing plate can be in the cunning
The right side of ring compresses the slip ring；The left surface of the sealing plate is fixed with a push rod, and the push rod can withstand on the end socket
On；Compression spring is provided between the end socket and the slip ring；The compression spring is enclosed on the outside of the push rod, and one
End is withstood on the slip ring, and the other end is withstood on the end socket；The left surface of the slip ring is additionally provided with guide cylinder in one, described
The right flank of end socket is provided with an outer guide cylinder, and the outer guide cylinder is enclosed on the outside of the interior guide cylinder, and the outer guiding
Cylinder relative can be slided with the interior guide cylinder.
The sealing plate includes pressing plate and the sealing ring being fixed on the pressing plate.
The end of the interior guide cylinder and the outer guide cylinder is provided with the hook part that can mutually catch on.
It is of the present utility model to be used for inflation film manufacturing machine pressure type relief valve using above-mentioned technical proposal, installed in the wind of inflation film manufacturing machine
On road, the air communication in air channel, when air pressure increases, is moved to the left slip ring and sealing plate to the inside of the body,
Until the push rod is withstood after the end socket, sealing plate can not continue to be moved to the left, but slip ring is still under pressure and is moved to the left
So that the one-way pressure valve of end socket unclamps, air is discharged to the left from the gap of end socket, complete pressure release；When air pressure reduces
When, one-way pressure valve is replied, while slip ring is resetted by the effect of compression spring, sealing plate is pressed on slip ring again and is completed
Sealing.It is of the present utility model to be used for inflation film manufacturing machine pressure type relief valve, it is simple in construction, it is with low cost, using pure mechanic structure, without
Other electronic equipments, therefore fault rate is relatively low, it is easy to maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As illustrated, the present embodiment provides inflation film manufacturing machine pressure type relief valve, include the body 1 of tubular, in the body
Left side is provided with transversely movable end socket 2, and the outside of end socket 2 is provided with one-way pressure valve 9, the right side of the body open set from
And enable air to enter body interior, be internally provided with slip ring 3 in the body 1, the periphery wall of the slip ring 3 with described
The madial wall sealing of body 1 is set and the slip ring can horizontally slip in the body 1；One sealing plate 4 can be described
The right side of slip ring 3 compresses the slip ring 3；The left surface of the sealing plate 4 is fixed with a push rod 5, and the push rod 5 can withstand on institute
State on end socket 2；Compression spring 6 is provided between the end socket 2 and the slip ring 3；The compression spring 6 is enclosed on the push rod 5
