Abstract
The utility model relates to an intake pipeline system of a pre-expander. The system comprises intake pipes and intake valves, wherein the intake pipes include an intake main pipe and first and second intake branches connected with the intake main pipe; the intake valves include a first intake valve, a second intake valve and a third intake valve; the first intake valve is arranged on the intake main pipe; the second and third intake valves are respectively arranged on the two intake branches. The system has the beneficial effects that the first, second and third intake valves are used cooperatively, thus greatly enhancing the capacity of adjusting the compressed air flow and improving the compressed air flow control accuracy; the system can conveniently and accurately adjust the compressed air to small flow required by the plastic foam production process, thus being beneficial to smooth operation of the plastic foam production process; the system is of a simple structure, is easy to manufacture, is low in production cost and has extensive market prospect.
Description
Technical field
The utility model relates to a kind of prefoaming machine air inlet pipeline system.
Background technology
The staving of plastic foam prefoaming machine commonly used bottom all is equipped with the bottom inflow valve gear at present, existing bottom inflow valve gear normally is fixed on and is combined on air inlet pipe by an intake valve, and this class bottom inflow valve gear controls by an intake valve compressed air require entered in plastic foam prefoaming machine staving in use.
When using the plastic foam prefoaming machine to prepare plastic foam, due to technologic needs, at certain one-phase, need to input the compressed air of low discharge to staving inside, and compressed-air actuated uninterrupted is also had to larger requirement.Use existing air inlet pipeline system to be difficult to conveniently, to be adjusted to the required flow compressed air of technique accurately, this just brings fixed difficulty to process adjustments, and affects the quality of product.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, easy to use, can realize what air mass flow was accurately controlled
In order to realize the foregoing invention purpose, the technical solution of the utility model is: a kind of prefoaming machine air inlet pipeline system, comprise air inlet pipe and intake valve, described air inlet pipe comprises air inlet supervisor and the first air intake branch and the second air intake branch that with the air inlet supervisor, are connected, described intake valve comprises the first intake valve, the second intake valve and the 3rd intake valve, it is upper that described the first intake valve is positioned at the air inlet supervisor, and the second intake valve and the 3rd intake valve lay respectively on two air intake branches.
Preferably, described the first intake valve, the second intake valve and the 3rd intake valve are angle pedestal valve.
Preferably, on described air inlet supervisor, also be provided with hand-operated valve.
The first intake valve of the present utility model, the second intake valve and the 3rd intake valve are used in conjunction with, thereby have greatly strengthened the regulating power to compressed air require, have improved controlling the accuracy of compressed air require size.The utility model can facilitate, be adjusted to accurately produces the required low discharge compressed air of plastic foam technique, is conducive to carrying out smoothly of plastics one foam production technique.The utility model is simple in structure, easy to manufacture, and production cost is low, and market prospects are wide.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with concrete the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1: a kind of prefoaming machine air inlet pipeline system, comprise air inlet pipe and intake valve, described air inlet pipe comprises air inlet supervisor 1 and the first air intake branch 2 and the second air intake branch 3 that with the air inlet supervisor, are connected, described intake valve comprises the first intake valve 4, the second intake valve 5 and the 3rd intake valve 6, described the first intake valve 4 is positioned on air inlet supervisor 1, the second intake valve 5 and the 3rd intake valve 6 lay respectively on two air intake branches, described the first intake valve 4, the second intake valve 5 and the 3rd intake valve 6 are angle pedestal valve, described air inlet master, also be provided with hand-operated valve 7 on 1.
Prefoaming machine air inlet pipeline system in the present embodiment is mainly used in controlling the flow that enters plastic foam prefoaming machine staving compressed air, in the present embodiment, an end of air inlet supervisor 1 is connected with compressed-air actuated source of the gas, the other end of air inlet pipe 1 is connected with two air intake branches, and two air intake branches are that the prefoaming machine staving is connected.Due to the different phase in the plastic foam production technology to compressed-air actuated demand difference, and compressed-air actuated consumption has larger impact to the quality of plastic foam product, the flow that enters prefoaming machine staving compressed air so accurately control has larger effect to the production of plastic foam.Prefoaming machine air inlet pipeline system in the present embodiment can realize especially can facilitating, be adjusted to accurately the required low discharge compressed air of plastic foam production technology to entering the accurate control of prefoaming machine staving compressed air flow by the adjusting of the first intake valve 4, the second intake valve 5 and the 3rd intake valve 6.
