Description

A kind of thermoregulator

Technical field

The utility model relates to gas engine part, more specifically for explosive motor water cooling system thermoregulator, is mainly used in the motor car engine water cooling system.

Technical background

At present, known thermoregulator is to be formed by inductor, valve, Returnning spring, valve seat and supporting frame combination.When engine temperature raise, inductor push rod setting in motion also drove valve open, and engine cooling water is flowed, and motor begins heat radiation.When engine temperature continues to raise, valve is also along with constantly opening, the flow of cooling water also constantly strengthens, the degree of heat radiation of motor is also constantly strengthened, thereby the temperature that makes motor rises slowly, when valve open arrives full-gear, and the flow maximum of cooling water, the radiating effect of motor is the strongest, and the engine temperature of this moment begins to descend.Decline along with engine temperature, the inductor push rod begins to fall after rise under the effect of Returnning spring, valve begins to close, the flow of cooling water is also along with minimizing, and the engine temperature rate of descent is slack-off, when engine temperature continues to reduce, the inductor push rod continues to fall after rise, valve continues to close until closing fully, and the main cooling water of motor this moment is no longer mobile, and motor stops cooling.Like this, in the working procedure of motor, engine temperature fluctuation up and down within the specific limits makes motor be in work in the certain temperature range under the effect of thermoregulator, thus the effect of playing the protection motor, cutting down the consumption of energy and discharge.But general in the market thermoregulator water flow in the process of control cooling water is extremely unstable, regulates also broad of temperature range, make the temperature fluctuation range of motor also bigger, thereby the energy consumption that causes is more relatively.General thermoregulator the protection motor, cut down the consumption of energy and the balance discharging aspect effect not ideal enough.

The model utility content

In order to overcome existing thermoregulator controlled water flow amount instability; the adjusting temperature range is wide; the phenomenon that the engine operating temperature fluctuation is big; the utility model provides a kind of improved thermoregulator; this thermoregulator not only can be sensitive the engine temperature of experiencing change; and the wave range of engine operating temperature is reduced greatly, motor is worked, the real effect that realizes the protection motor, cuts down the consumption of energy and reduce noxious gas emission under than the stationary temperature state.

The utility model is realized in the following manner: a kind of thermoregulator, form by parts such as inductor, valve, spring, valve seat and supports, gas bleeder valve is arranged on the valve seat, in parallel one auxiliary thermoregulator on main thermoregulator, its main constituent elements is identical with main thermoregulator; The thermoregulation range of main and auxiliary thermoregulator is provided with difference.

Main thermoregulator inductor and valve closely connect together, have valve port on the valve seat, the bossed locating slot in valve port top, valve port is little than valve size, the push rod top of inductor withstands in the locating slot of valve seat top, spring one end rest valve, the other end withstands on the support that valve seat swells below, this support and valve seat are fixedly connected into the cage shape, auxiliary thermoregulator is fixedly connected on the main thermoregulator valve seat, the auxiliary more main thermoregulator valve port of thermoregulator valve port size is smaller, auxiliary thermoregulator can be riveted on the main thermoregulator valve seat, the center of top of auxiliary valve seat has the positioning round orifice of inductor, the cyclic spring body sealing ring that embedding is arranged on the auxiliary valve port periphery below main valve seat, the auxiliary induction body of middle part projection is inserted in the Auxiliary valves mouth by the following activity of main valve seat, and the positioning rod at its auxiliary push-rod top is inserted in the positioning round orifice, and inductor body bottom is by the spring sheet rest that is riveted on the main thermoregulator valve seat.

Main thermoregulator inductor is identical with the structure of auxiliary thermoregulator inductor, it is inconsistent that temperature sensor just is set, its body is a round barrel shape, interior dress temperature-sensitive wax, its oral area and guide pin bushing tight riveting, the centre accompanies diaphragm, be followed successively by in the inner chamber of top, the guide pin bushing of diaphragm semifluid, plunger, pad, push rod, with the positioning rod of push rod disjunctor.

The purpose of setting up Auxiliary valves is that the peak value size is closed in the switching of balance adjustment master thermoregulator.Auxiliary thermoregulator is made as different temperature regulating range respectively with main thermoregulator, when engine temperature is higher, begin to open at main thermoregulator and lower the temperature when regulating, auxiliary thermoregulator has begun cooling already in advance to be regulated, thereby the flow of cooling water is increased relatively, and engine temperature descends rapidly.Same principle when engine temperature is low, begins to close at main thermoregulator and heats up when regulating, and auxiliary thermoregulator has begun in advance already to heat up and regulated, thereby the flow of cooling water is reduced rapidly, and motor also heats up rapidly.Like this, under the coordinative role of main and auxiliary thermoregulator, cooling water remains comparatively stable flow rate in the engine temperature change procedure, thereby the effect that makes thermoregulator regulate temperature obviously improves, the operating temperature wave range of motor obviously reduces, and reaches the purpose that motor is worked in narrower temperature range.

The beneficial effects of the utility model are: can make motor be in work (see figure 2) in the less temperature fluctuation range, because the thermal coefficient of expansion of motor moving element is not quite identical, so can solve the moving element matching gap variation problem greatly that causes greatly because of the engine body temperature fluctuation, thereby play effective protection motor, farthest cut down the consumption of energy and reduce the effect of harmful exhaust emissions; And this novel installing and using with thermoregulator is identical normally, versatility is extremely strong.

In Fig. 1, when engine temperature was not high, cooling water flowed out from water pump (6), Flow into machine cooler (4) through water inlet pipe (10) and partial circulating effluent pipe mouth (3), be cooled Water flow back to water pump (6) by partial circulating return pipe (5). When engine temperature is higher, The high-temperature water that comes out from water pump (6) thermosistor (2) of will flowing through, and by the systemic circulation water outlet The mouth of pipe (1) inflow radiator (8), under the cooling of fan and radiator, high-temperature water is fast The prompt drop temperature flows back to water pump (6) by systemic circulation return pipe (7) afterwards. Generally, transfer The temperature device comes control engine to fall according to the temperature of engine in the mode of control cooling water flow Temperature speed. Aspect the flow of control cooling water, auxiliary thermosistor valve (2-6) plays The important function of replenishing begins cooling or heats up to regulate initially at main thermosistor, makes the accent of flowing through The flow of cooling water of the temperature device state that tends towards stability, thus unlatching and pass at valve solved Cooling water flow instability in the closed procedure, suddenly big or suddenly small, neglect the anxious slow phenomenon of neglecting. Thereby make The operating temperature fluctuation range of engine is dwindled greatly, has realized that finally engine is comparatively permanent The purpose of work in the fixed temperature range, as shown in Figure 2.
