Abstract
The utility model discloses a vacuum sizing is decompression alarm device for case, including installing electric contact pressure gauge, alarm and the admission valve on the sizing case of vacuum, still include the vacuum pump of being connected with vacuum sizing case, be provided with an upper limit stationary contact, a lower limit stationary contact and a movable contact in the electric contact pressure gauge, upper and lower limit stationary contact links to each other with the alarm through respective wire. The utility model discloses an alarm that installs electric contact pressure gauge additional and be connected with electric contact pressure gauge on the sizing case of vacuum, the vacuum pressure and the suggestion of reporting to the police in the sizing case of ability real -time detection vacuum, the production of having stopped to lead to the fact the less than normal or phenomenon bigger than normal of tubular product external diameter because of the vacuum decompression has improved product quality and product percent of pass.
Description
Technical field
This utility model relates to a kind of alarm device, more specifically, particularly relates to a kind of device that vacuum pressure in sizing tank can be detected and report to the police, belongs to plastic tube extrusion field shaping technique.
Background technology
In the vacuum sizing operation of PVC, tubing is to be cooled down by the shower water in vacuum sizing box, before product cools down for the first time, the pumped vacuum systems that vacuum tank carries is utilized to be got rid of by the air in casing, make to be formed in casing negative pressure, allow the outer wall of product and the inwall of calibration sleeve be close to by negative pressure and realize sizing molding.But in process of production, vacuum leak can be made because discharging speed shakiness causes tube outer diameter to draw and attenuate, vacuum pressure is caused to decline, cause that product external diameter is less than normal, reply normal vacuum pressure such as discharging speed and also can become big therewith, this process is not because installing relevant alarm device so that not easily finds the change of product external diameter in production in time, causes that product fraction defective increases.
Utility model content
The purpose of this utility model is in that for above-mentioned the deficiencies in the prior art, a kind of vacuum sizing box decompression alarm device of air is provided, vacuum pressure in sizing tank body detected and reports to the police, stopping to cause because of vacuum decompression the generation of tube outer diameter phenomenon less than normal or bigger than normal.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vacuum sizing box decompression alarm device of air, including the electro connecting pressure gauge being arranged on vacuum sizing box, alarm and intake valve, also include the vacuum pump being connected with vacuum sizing box, being provided with a upper limit stationary contact, a lower limit stationary contact and an armature contact in described electro connecting pressure gauge, described upper and lower limit stationary contact is connected with alarm by respective wire.
This utility model by installing electro connecting pressure gauge and the alarm with electric contact pressure list catenation additional on vacuum sizing box, the vacuum pressure in vacuum sizing box can be detected in real time and carry out alarm, stop to cause because of vacuum decompression the generation of tube outer diameter phenomenon less than normal or bigger than normal, improve product quality and conforming product rate.

Detailed description of the invention
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but is not intended that any restriction of the present utility model.
As shown in Figure 1, a kind of vacuum sizing box decompression alarm device of air provided by the utility model, including the electro connecting pressure gauge 2 being arranged on vacuum sizing box 1, alarm 4 and intake valve 5, also include the vacuum pump 7 being connected with vacuum sizing box 1, being provided with two stationary contacts (i.e. upper limit stationary contact and lower limit stationary contact) and an armature contact in described electro connecting pressure gauge 2, described upper and lower limit stationary contact is connected with alarm 4 by respective wire 3.
When tubing 6 cooling and shaping in vacuum sizing box 1, the vacuum pressure in vacuum sizing box 1 is detected in real time by electro connecting pressure gauge 2, on in case, force value exceedes, during lower limit set value, the armature contact of electro connecting pressure gauge 2 is connected with the upper limit or lower limit stationary contact and touches, thus connecting alarm 4, alarm 4 sends alarm immediately, pressure in vacuum sizing box 1 is adjusted by prompting operator, open intake valve 5 pass in vacuum sizing box 1 air or start vacuum pump 7 vacuum sizing box 1 is carried out evacuation, the vacuum in vacuum sizing box 1 is made to be maintained at the state of a balance, stop to cause the generation of tube outer diameter phenomenon less than normal or bigger than normal because of vacuum decompression, improve product quality and conforming product rate.
