Description
Technical field
The present invention relates to the oil cooling apparatus that loading machine, air compressor etc. use, particularly, relate to the plate-fin heat exchanger of band pressure-temperature control valve.
Background technology
At present, in the plate-fin heat exchanger of loading machine, air compressor, when the plate-fin heat exchanger interior oil during at low temperature viscosity higher, when pressure reduction surpasses certain limit, cause the core body spalling easily, make plate-fin heat exchanger damage leakage of oil and lost efficacy.Simultaneously, when operate as normal, the momentary pulse high pressure may appear in system, causes the core spalling, makes plate-fin heat exchanger damage leakage of oil and inefficacy.
As seen, in the prior art, also do not have a kind of plate-fin heat exchanger to possess the ability of low temperature overload protection and instantaneous pressure overload protection simultaneously, its poor reliability, service life lack.
Summary of the invention
The objective of the invention is to,, propose a kind of plate-fin heat exchanger that is provided with pressure-temperature control valve, bypass pipe, to realize the advantage of good reliability and long service life at the problems referred to above.
For achieving the above object, the technical solution used in the present invention is:
The plate-fin heat exchanger of band pressure-temperature control valve, comprise core body, first end socket, second end socket and bypass pipe, described first end socket, core body and second end socket are connected successively, on described first end socket, establish oil-in, set out hydraulic fluid port on described second end socket, described first end socket is communicated with by the pressure-temperature control valve with bypass pipe.
Further be improved to, the pressure-temperature control valve comprises temperature controller, spool A, spring, spool B and valve seat, described spool B and valve seat are cavity structure and are provided with fuel feed hole and oil outlet, described temperature controller is connected up and down with spool A and forms a construction unit, the socket successively from inside to outside of this construction unit and spring, spool B, valve seat; Spool A is a cavity structure, its outside winding block or projection.
Moreover fuel feed hole is established in valve seat bottom, spool B bottom, and described valve seat sidepiece, spool B sidepiece set out oilhole.Described spool B external diameter is greater than valve seat bottom fuel feed hole footpath, the spring external diameter greater than spool B at the bottom of the oil-feed aperture.
When the temperature of plate-fin heat exchanger oil-in during 55-70 degree centigrade of scope; the pressure-temperature control valve is opened automatically; valve seat bottom fuel feed hole, spool B bottom fuel feed hole, spool B sidepiece oil outlet and valve seat sidepiece oil outlet are communicated with successively; interior media flows into bypass pipe, second end socket through first end socket, pressure-temperature control valve; after oil-out discharge; both can play the low temperature overload protective function; system temperature is raise rapidly, when system's cold start-up, play the effect of increasing work efficiency.
When the temperature of plate-fin heat exchanger oil-in surpassed 70 degrees centigrade, the pressure-temperature control valve was closed.If system the momentary pulse high pressure occurs and surpasses the certain limit value; under pressure; spool B moves on the whole and compresses spring; valve seat bottom fuel feed hole directly is communicated with valve seat sidepiece oil outlet; interior media flows into bypass pipe, second end socket through first end socket, pressure-temperature control valve;, play the instantaneous pressure overload protective function after oil-out is discharged.
Find out from above-mentioned situation; plate-fin heat exchanger of the present invention can overcome that heat exchanger only has single high pressure overload protection in the prior art; and there is not the defective of low temperature overload protection function; operating efficiency when having improved the cooling system cold start-up further improves the reliability of plate-fin heat exchanger, further prolong service life.
Below by drawings and Examples, technical scheme of the present invention is further described.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
The plate-fin heat exchanger of band pressure-temperature control valve, as shown in Figure 1, comprise core body 3, first end socket 2, second end socket 5 and bypass pipe 6, first end socket 2, core body 3 and second end socket 5 are connected successively, wherein, first end socket 2 and second end socket 5 are located at the right side and the left side of core body 3 respectively, bypass pipe 6 is located at the upside of core body 3 and between first end socket 2 and second end socket 5, on first end socket 2, establish oil-in 4, setting out hydraulic fluid port 7, the first end sockets 2 on second end socket 5 is communicated with by pressure-temperature control valve 1 with bypass pipe 6.
As shown in Figure 4, pressure-temperature control valve 1 comprises plug screw 11, sealing gasket 12, temperature controller 13, spool A14, spring 15, spool B16 and valve seat 17; Spool B16 and valve seat 17 are cavity structure, and fuel feed hole is established in valve seat bottom, spool B bottom, and valve seat sidepiece, spool B sidepiece set out oilhole, and spool B16 external diameter is greater than fuel feed hole footpath, valve seat bottom, spring 15 external diameters greater than spool B at the bottom of the oil-feed aperture; Temperature controller 13 is connected up and down with the spool A14 of cavity structure and forms a construction unit, the socket successively from inside to outside of this construction unit and spring 15, spool B16, valve seat 17; Spool A14 outside winding block or projection can be blocked spring, prevent to scurry on the spring.
Shown in Fig. 2-3, when pressure-temperature control valve 1 was in opening, valve seat bottom fuel feed hole, spool B bottom fuel feed hole, spool B sidepiece oil outlet and valve seat sidepiece oil outlet were communicated with successively, and bleed off circuit is open-minded; When pressure-temperature control valve 1 was in closure state, valve seat bottom fuel feed hole and spool B bottom fuel feed hole were blocked in spool A bottom, thereby close bleed off circuit.
When interior media temperature during 55-70 degree centigrade of scope; pressure-temperature control valve 1 can be opened bleed off circuit automatically; valve seat bottom fuel feed hole; spool B bottom fuel feed hole; spool B sidepiece oil outlet and valve seat sidepiece oil outlet are communicated with successively; interior media is without core body 3; directly through first end socket 2; pressure-temperature control valve 1 flows into bypass pipe 6; and through second end socket 5 and oil-out 7 outflows; thereby avoid the plate-fin heat exchanger interior media big because of viscosity when low temperature; internal pressure drops is excessive to cause the core body spalling; can play the low temperature overload protective function; system temperature is raise rapidly, when system's cold start-up, play the effect of increasing work efficiency.
When the oil temperature of plate-fin heat exchanger oil-in surpassed 70 degrees centigrade, pressure-temperature control valve 1 was in closed condition.If system the momentary pulse high pressure occurs and surpasses the certain limit value; spool B16 moves on the whole and compresses spring 15; valve seat bottom fuel feed hole directly is communicated with valve seat sidepiece oil outlet; interior media flows into bypass pipe 6, second end socket 5 through first end socket 2, pressure-temperature control valve 1;, play the instantaneous pressure overload protective function after oil-out is discharged.
