Abstract

The utility model relates to a built-in waxiness temperature adjusting valve type cooler for ships, composed of a cooler body, an adjusting valve, etc. The built-in wax temperature adjusting valve type cooler is characterized in that a waxiness temperature adjusting valve is arranged inside the cooler, and the waxiness temperature adjusting valve is composed of a valve body, a sphere, an action element and a thermal element, wherein, the action element is composed of a return spring and a drive rod, and the thermal element is composed of a sleeve, an ejector rod, a guide pipe, a sealing rubber pipe, a machine case and a temperature sensing wax. The utility model is fixed on a baffle plate by the sleeve and locking nuts and then is immersed into oil, and can be widely used for fresh water circulation system of diesel engines or the cooling circulation system of lubricating oil.

Description

Temp. control valve type cooler with wax therein

A kind of built-in wax temperature control valve (TCV) formula cooler that is used for diesel engine fresh water or lubricant oil cooling recirculation system relates to cooling technology peculiar to vessel field.

Present fresh water or lubricant oil cooling recirculation system, because at the outside temperature control valve (TCV) of installing of cooler, so the cost height, system architecture complexity, poor reliability, if make water, the cooling of wet goods temperature, it is low excessively to produce temperature, influences the heating efficiency of main frame, increases oil consumption, so energy consumption is big, to energy-conservation unfavorable.

Goal of the invention of the present utility model is to propose the built-in wax modulating valve formula cooler that a kind of cost is low, reliability is high, energy consumption is little, and it can improve the main frame heating efficiency, reduces oil consumption and system architecture is oversimplified, and it also has the ability of variable cooling.

The utility model is made up of modulating valve, cooler body, end cap (12), contains cooling tube (10) in the cooler body; The wax temperature control valve (TCV) is arranged in the cooler, it is made up of valve body (1), spheroid (2), executive component, thermosensitive element, wherein executive component is made up of returning spring (4), the flanged drive link of afterbody (5), water-inlet cavity wall and spheroid (2) that the head of drive link (5) passes valve body (1) offset, the returning spring (4) that is enclosed within on the drive link (5) places water-inlet cavity, and the afterbody of drive link (5) and the power sensing head of thermosensitive element are inconsistent; Thermosensitive element is shaft-like, it is by cover (8), push rod (14), conduit (15), sealed rubber pipe (16), housing (17) and temperature-sensitive wax (13) are formed, sealed rubber pipe (16) is inserted housing (17), push rod (14) inserts in the sealed rubber pipe (16), conduit (15) is enclosed within outside the push rod (14), the outer cover (8) that is provided with of conduit (15), be full of temperature-sensitive wax (13) in the space between housing (17) and sealed rubber pipe (16), thermosensitive element is fixed on the isolating plate (7) between cooler body and the modulating valve by cover (8) and locking nut (6), and in the oil in the immersion cooler, when the oil temperature surpasses the fusing point of temperature-sensitive wax (13), temperature-sensitive wax (13) therefore expands rapidly, volume increases, extruding sebific duct (11), force push rod (14) to be subjected to displacement and make spheroid (2) move by the drive link in the executive component (5), thereby open water intake, then cooling water enters water-inlet cavity, the cooling tube (10) of flowing through, final by water outlet, to reach cooling purpose.After cooled oil temperature is being reduced to the fusing point of temperature-sensitive wax (13), temperature-sensitive wax (13) shrinks, volume reduces rapidly, meanwhile, returning spring (4) acts on push rod (6) by drive link (5), and it is resetted, spheroid (2) self-return under flow action, thereby close water intake, stop cooling.

Compared with prior art, because the utility model has replaced the past with bellows or bimetallic strip method etc. with extraordinary temperature-sensitive wax, thereby make it integrated, and it is big to have thrust, power is big, under the effect of 10kg power, almost not decay has overcome use bellows element, the tangible weakness of memory alloy element load effect, and it has also overcome shortcomings such as outside reload temperature modulating valve cost is too high, water wet goods temperature power consumption of cooling is big, thereby it is low to have cost, and system architecture is simple, reliable.In addition, because extraordinary temperature-sensitive wax is when its fusing point is above, its volume constantly increases along with the rising of temperature, and so temperature is high more, the supply of cooling water is big more, increases so its cooling capacity raises with temperature, and in addition, it also has advantages such as life-span length.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the local A-A revolved sectional view of the utility model thermosensitive element.

The utility model can be achieved like this: the drive link (5) in (as shown in Figure 1) executive component passes the water-inlet cavity wall and props up spheroid (2) after being inserted in returning spring (4), the push rod of its afterbody and thermosensitive element (6) is inconsistent, extraordinary temperature-sensitive wax is inserted in the housing (17) of thermosensitive element, the sealed rubber pipe (16) of behind exhausting air, packing into, conduit (15) and push rod (14), with oil hydraulic press with housing (17) flange, it is coupled together, and be placed in the cooler body, utilize cover (8) and locking nut (6), be fixed on the isolating plate (7), for preventing to leak and nut loosening, increase O type circle herein and on the screw thread of locking nut (6), be stained with glue, spheroid (2) is inserted by auxiliary hole, and fills out dead auxiliary hole behind the relative position of adjusting drive link (5) and spheroid (2).
