Abstract
The utility model relates to an improved multi-functional integral valve, which can ensure the temperature control performance. The improved multi-functional integral valve comprises a valve body, an oil filter, an oil cut-off valve part, a temperature control valve core component, an oil cooler and a cavity end cover, wherein the oil cut-off valve part is embedded in the valve body; the a temperature control cavity is arranged in the valve body; and the temperature control valve core component is arranged in the temperature control cavity. The improved multi-functional integral valve is characterized in that an annular step is arranged in the temperature control cavity; after the annular step are matched with the temperature control valve core component, the temperature control cavity is divided into a hot oil cavity and a cold oil cavity; the hot oil cavity is communicated with the oil filter; the cold oil cavity is communicated with the oil cooler; an oil outlet is arranged at the circumference surface of the temperature control valve core component; the temperature control valve core component is axially provided with a driving device; and one axial end of the temperature control valve core component is closed, and the other axial end thereof is communicated with a hot oil inlet.
Description
(1) technical field
The utility model relates to helical-lobe compressor oil circuit device field, is specially a kind of modified model multifunction integrated valve.
(2) background technique
Existing helical lobe compressor oil way system multifunctional pile-up valve is integrated in oil cut-off valve, heat-operated valve, oil strainer and differential pressure switch etc. in the valve body, finishes unit oil lubrication system control function under each operating mode of compressor.But in actual motion, because its temperature control structure inside, only single change deep fat passage does not change to the passage of cooler oil, so is lower than under the operating mode of 40% carrying capacity the function of temperature control deficiency of this multifunction integrated valve at helical-lobe compressor.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of modified model multifunction integrated valve, and it can guarantee its temperature-control performance.
Its technological scheme is such: it comprises valve body, oil strainer, embed the oil cut-off valve parts in the valve body, the temperature controlled valve core assembly, oil cooler, the cavity end cap, described valve inner has the temperature control cavity, in the described temperature control cavity temperature controlled valve core assembly is housed, it is characterized in that: in the described temperature control cavity ring-shaped step is arranged, described ring-shaped step cooperates installation with described temperature controlled valve core assembly after, described temperature control cavity is divided into the deep fat chamber, the cold oil chamber, described deep fat chamber is communicated with described oil strainer, described cold oil chamber is communicated with described oil cooler, the circumferential surface of described temperature controlled valve core assembly has oil outlet, described temperature controlled valve core assembly drive unit axially is housed, the end sealing that described temperature controlled valve core assembly is axial, the other end is communicated with hot oil inlet.
It is further characterized in that: described axial drive means specifically comprises spring, flexible rod, described temperature controlled valve core assembly specifically comprises temperature controlled valve core, thermometer bulb body, described thermometer bulb body is close to described temperature controlled valve core, described temperature controlled valve core one end is by described thermometer bulb body sealing, described thermometer bulb body connects described flexible rod one end, the described flexible rod the other end connects described cavity end cap, and described spring one end press-fits in described temperature controlled valve core inwall, and the described spring the other end press-fits the inwall in described valve body.
In the said structure of the present utility model, the temperature control cavity is divided into the deep fat chamber, the cold oil chamber, the circumferential surface of described temperature controlled valve core assembly has oil outlet, described temperature controlled valve core assembly drive unit axially is housed, the end sealing that described temperature controlled valve core assembly is axial, the other end is communicated with hot oil inlet, after its deep fat enters described temperature controlled valve core assembly, under original state, only flow into described deep fat chamber by described oil outlet, temperature in the described deep fat chamber rises fast, when temperature arrives certain value, described drive unit will promote described temperature controlled valve core assembly axial action, change the relative position of described oil outlet and described ring-shaped step, when the aperture of described oil outlet during by described ring-shaped step, deep fat enters into described cold oil chamber, be accompanied by described temperature controlled valve core assembly to action, the flow that enters into the flow in described deep fat chamber and the enter into described cold oil chamber relationship change that is inversely proportional to, it can guarantee the temperature-control performance of multifunction integrated valve.
(4) description of drawings
Fig. 1 is the structural representation of plan view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
(5) embodiment
See Fig. 1, Fig. 2, the utility model comprises valve body 1, oil strainer 2, embed the oil cut-off valve parts 3 in the valve body, temperature controlled valve core 4, thermometer bulb body 5, oil cooler (is existing mature structure, do not draw among the figure), valve body 1 inside has the temperature control cavity, temperature controlled valve core 4 is housed in the temperature control cavity, thermometer bulb body 5, ring-shaped step 6 is arranged in the temperature control cavity, ring-shaped step 6 cooperates installation with temperature controlled valve core 4 after, the temperature control cavity is divided into deep fat chamber 7, cold oil chamber 8, deep fat chamber 7 is communicated with oil strainer 2, cold oil chamber 8 is communicated with oil cooler by passage 14, the same axial circumferential surface of temperature controlled valve core 4 is evenly equipped with a plurality of oil outlets 9, temperature controlled valve core 4 axial ends are by 5 sealings of thermometer bulb body, the other end is communicated with hot oil inlet 10, thermometer bulb body 5 is close to temperature controlled valve core 4, and thermometer bulb body 5 connects flexible rod 11 1 ends, and flexible rod 11 the other ends connect cavity end cap 12, spring 13 1 ends press-fit in temperature controlled valve core 4 inwalls, and spring 13 the other ends press-fit in the inwall of valve body 1.
Its working principle is as follows: during initial position, deep fat can only enter deep fat chamber 7 by oil outlet 9, can not flow into cold oil chamber 8, and deep fat can not enter the oil cooler cooling, and temperature rises fast.When temperature reaches certain value, flexible rod 11 stretches out, promote thermometer bulb body 5, temperature controlled valve core 4 to cold oil chamber 8 side shiftings, change the relative position of oil outlet 9 and ring-shaped step 6, after the aperture of oil outlet 9 moved past ring-shaped step 6, the oil-feed flow in cold oil chamber 8 increased gradually, and the oil-feed flow in deep fat chamber 7 reduces gradually, oil in the deep fat chamber 7 flows into cold oil chambeies 8 from oil outlet 9 after instead flowing into temperature controlled valve cores 4 inside via oil outlet 9 again, and the deep fats in the cold oil chamber 8 enter the oil cooler cooling.
