Abstract
The utility model provides a measuring control valve for a liquid material proportion of a polyurethane high-pressure foaming machine, which comprises a valve body 1 which is provided with a raw material inlet flow channel 2, a raw material internal circulation flow channel 3 and a raw material outlet flow channel 4. The utility model is characterized in that the valve body 1 is provided with a columnar valve core 5 which can make a straight reciprocating motion, and the valve core 5 is provided with an L-shaped flow channel 6. When the raw material internal circulation flow channel 3 is conducted, the raw material outlet flow channel 4 is cut off; when the raw material outlet flow channel 4 is conducted, the raw material internal circulation flow channel 3 is cut off. A control valve with the structure has the advantages of tight sealing, no raw material leakage, simple structure and little possibility of component abrasion.
Description
The utility model relates to the liquid material ratio measuring control valve of a kind of equipment that is used to make polyurethane high-pressure foam goods, particularly polyurethane high pressure foaming machine.
The mensuration of the liquid material mixed proportion of polyurethane high pressure foaming machine is to realize by the moment flow of two kinds of raw materials before mixing of measuring in the liquid material system.In known technology, the liquid material of the polyurethane high pressure foaming machine that Italy Kang Long company produces is more more advanced than measuring control valve, it comprises valve body, have raw material on the valve body and enter circulatory flow and raw material outflow runner in runner, the raw material, rotating the control of pillar spool enters runner and interior circulatory flow, flows out the conducting of runner and end, when spool during interior circulatory flow conducting, the outflow runner ends, when the spool handle flows out the runner conducting, interior circulatory flow ends, by a rotation of doing the rack drives spool of straight reciprocating motion.The control valve complex structure of this structure, parts wear and tear easily, rotate the pillar seal spool and sternly do not cause raw material to leak, and condensing after two kinds of raw materials of leakage meet makes control valve malfunctioning.
The purpose of this utility model is to provide a kind of liquid material ratio measuring control valve of polyurethane high pressure foaming machine, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of liquid material ratio measuring control valve of polyurethane high pressure foaming machine, it comprises valve body 1, have raw material on the valve body 1 and enter runner 2, circulatory flow 3 and raw material flow out runner 4 in the raw material, its improvements are to have the pillar spool 5 that can do straight reciprocating motion on the valve body 1, pillar spool 5 has " L " type runner 6, in pillar spool 5 enters raw material runner 2 and raw material during circulatory flow 3 conductings, raw material flows out runner 4 to be ended, when pillar spool 5 entered runner 2 with 4 conductings of raw material outflow runner to raw material, circulatory flow 3 ended in the raw material.
The liquid material ratio measuring control valve of the utility model polyurethane high pressure foaming machine can be a pillar spool 5 to be entered runner 2 with raw material to contact the sealing surface that forms is the conical surface.
The liquid material ratio measuring control valve of the utility model polyurethane high pressure foaming machine can be that pillar spool 5 is connected with hydraulic driving element.
The liquid material ratio measuring control valve of the polyurethane high pressure foaming machine that the utility model provides, simple in structure, parts are not easy to wear, and sealing is tight, and raw material does not leak.
Fig. 1, the structure sectional view of the liquid material ratio measuring control valve of the utility model polyurethane high pressure foaming machine.
The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.
Embodiment 1, Fig. 1 has provided the concrete structure of the liquid material ratio measuring control valve of present embodiment polyurethane high pressure foaming machine, as shown in the figure, it has valve body 1, have raw material on the valve body 1 and enter runner 2, circulatory flow 3 and raw material flow out runner 4 in the raw material, has the pillar spool 5 that to do straight reciprocating motion on the valve body 1, pillar spool 5 has " L " type runner 6, in pillar spool 5 enters raw material runner 2 and raw material during circulatory flow 3 conductings, raw material flows out runner 4 to be ended, when pillar spool 5 entered runner 2 with 4 conductings of raw material outflow runner to raw material, circulatory flow 3 ended in the raw material.Pillar spool 5 and raw material enter runner 2, and to contact the sealing surface that forms be the conical surface.Pillar spool 5 is connected with hydraulic driving element, can be the spool that a hydraulic driving element drives a control valve, also can be the spool that a hydraulic driving element drives two control valves.When pillar spool 5 is positioned at left stop, circulatory flow 3 conductings in the raw material, raw material flows out runner 4 to be ended, when pillar spool 5 is positioned at right stop, circulatory flow 3 ends in the raw material, raw material flows out runner 4 conductings, and liquid material flows out runner 4 from raw material and flows out, according to the mixed proportion of two kinds of raw materials of transient flow flow measurement of raw material.
