Abstract
The utility model relates to a hot winding arrangement wall tubular product preparation technical field, concretely relates to plastic melt distribution valve. The distribution valve includes valve body and the case that is located the valve body, and the valve body lateral wall is equipped with a feed inlet and two discharge gates, and the position that corresponds with two discharge gates on the case is equipped with the bleeder valve that matches with the discharge gate respectively. Compared with the prior art, the utility model, beneficial effect is: can easily realize the distribution to the fuse -element, the energy saving reduces the energy consumption, practices thrift the equipment investment.
Description
Technical field
The utility model relates to hot winding structure wall pipe preparing technical field, is specifically related to a kind of plastic melt distribution valve.
Background technology
When hot winding structure is produced, because of the diameter of tubing and the difference of structure, when producing, sometimes inwall or outer wall may only be done, or produce inside and outside wall by interior wall mould and outer wall mould simultaneously, when producing inside and outside wall simultaneously, the material weight of inwall and outer wall is different, if adopting two different forcing machines, will cause having a forcing machine not run or inefficient operation, when forcing machine does not run, normal operation is also wanted in the heating of forcing machine and runner, otherwise produce and can not normally carry out, this just causes the waste of the energy and equipment. because the material of inwall and outer wall is identical, thus by a device, the melt body flow of inwall or outer wall is carried out a certain proportion of distribution, just can produce inwall or the outer wall of tubing with a forcing machine, energy consumption can be reduced like this, save facility investment.
The structure of fritz adopts upper and lower two independent spools in the past, each spool is with independent driving mechanism, on spool threaded, the flange fixing with valve body is also threaded, driving mechanism drives Spool rotating, under the effect of screw thread, spool just can move up and down, thus the melt body flow of the upper lower discharge port of adjustment. The High Temperature High Pressure melt body extruded from forcing machine enters distribution valve from opening for feed, pressure (can reach 30MPA) and temperature (at 190-240 DEG C) in distribution valve are very high, when this kind severe, material and the requirement on machining accuracy of distribution valve body and spool is very high, extremely difficulty reaches the requirement used reliably and with long-term, thus spool and screw thread are together with the threaded engagement of valve flange, or cause valve core movement offside because sensor (under the high temperature conditions very easily damage) damages, cause the equipment can not normal operation.
Summary of the invention
The purpose of this utility model is to solve the problem, it is provided that a kind of plastic melt distribution valve.
The utility model is provided with integral type valve core, and single drive unit drives, and controls the melt flow of inwall and outer wall. On a spool, two angled sprues (bleeder valve) are set, adjust the folding ratio of two discharge ports, thus adjust flow. The High Temperature High Pressure melt body entered from opening for feed carries out valve body, two sprues can be produced very big thrust, the thrust produced on two sprues is identical, because spool is one, the power in two directions is cancelled out each other, therefore melt body because moving axially by power, simultaneously because spool is provided with sealing material, can not be sealed in valve body by spool. The ratio folding of two discharge ports can be adjusted respectively by the rotating of deceleration motor, or standard-sized sheet, or entirely close.
In order to reach the novel object of above-mentioned practicality, the utility model by the following technical solutions:
A kind of plastic melt distribution valve, described distribution valve comprises valve body and is positioned at the spool of valve body, and body wall is provided with an opening for feed and two discharge ports, and spool is respectively equipped with the bleeder valve matched with discharge port with the correspondence position of two discharge ports.
As preferably, spool comprises mandrel, mandrel is respectively equipped with bleeder valve with the correspondence position of two discharge ports.
As preferably, two bleeder valves are separated with angle difference mutually.
As preferably, bleeder valve comprises the connection section being connected with mandrel and the shielding portion for covering discharge port, the outer side of shielding portion is the circular arc face matched with body cavity, and the interior side of shielding portion is connected with connection section, and connection section and mandrel are connected.
As preferably, being provided with bearing bottom valve body, top is provided with step-down gear, is connected with bearing bottom spool, and top is connected with step-down gear.
As preferably, step-down gear has support.
As preferably, being provided with the sealing member for sealed valve core and valve body bottom valve body.
Compared with prior art, useful effect is the utility model: can easily realize the distribution to melt, save energy, reduces energy consumption, saves facility investment.
