Abstract
The utility model provides an anti-low-temperature-environment oil heat radiator. The heat radiator is provided with an oil inlet pipe, an oil outlet pipe and a heat radiator sheet, wherein a bypass pipeline is arranged between an outlet of the oil inlet pipe and an outlet of the oil outlet pipe, and the bypass pipeline is directly connected with oil requirement equipment. A valve port is arranged at a position where the bypass pipeline corresponds to the outlet of the oil inlet pipe, the valve port is connected with a flow control valve, and a valve core is arranged at the outlet position of the oil inlet pipe. The flow control valve comprises an installation base, the valve core, a temperature sensor, a spring and a sealing plug. The anti-low-temperature-environment oil heat radiator is simple in structure, an existing heat radiator does not need to be largely transformed, only the bypass pipeline needs to be additionally installed, and the flow control valve is further installed, so that the flow control is achieved along with the change of temperature. Under a high temperature state that oil has good fluidity, the bypass pipeline is closed under the control of the flow control valve, the normal operation of original equipment is not affected, and therefore the anti-low-temperature-environment oil heat radiator is convenient and swift to use and capable of saving the cost.
Description
Technical field
The utility model relates to a kind of anti-low temperature environment oil radiator.
Technical background
In cooling system, when oil radiator is in low temperature, because temperature is excessively low, the too poor internal system that causes of oil mobility is for shortage of oil, the problem that appearance equipment breaks down after can't starting or start very soon, therefore need a kind of device guarantee that oil radiator equipment under cryogenic conditions can normally start, and can be because oil mobility be poor the generation fault.
The utility model content
In order to overcome above problem, the utility model provides a kind of anti-low temperature environment oil radiator, this radiator is when indoor/outdoor temperature-difference is large, make device start when the low temperature by the low temperature bypass control device, the system fuel feeding of making is guaranteed, generation failure problems in the short time had promoted the security of product after the equipment of preventing can't start or start, and had got rid of the fuel feeding problem.
For solving above technical problem, the utility model provides following technical scheme: described radiator has oil inlet pipe, flowline and radiator fin, is provided with bypass line between oil inlet pipe outlet and flowline outlet, and described bypass line directly connects the oily equipment that needs; Be provided with valve port with oil inlet pipe outlet corresponding section on the bypass line, this valve port connection traffic control valve, spool is located in the oil inlet pipe exit.
Further, described flow control valve comprises mount pad, spool, temperature sensor, spring and shutoff;
Mount pad is fixed on the valve port place, and mount pad has internal thread;
Spool is column, and spring housing is at spool external compression spring,
Temperature sensor is connected with spool, is installed in the mount pad with spool with spring;
Shutoff is barrel-shaped, and sidewall has external screw thread, be connected with the mount pad internal thread, temperature sensor since the elastic force effect top set of spring in shutoff.
Further, described spool one end has shoulder, and Spring Card is at shoulder;
Further, the other end of described spool has radial slot.
Further, described temperature sensor has push rod, and this push rod top set is in shutoff.
Further, has gasket seal between described shutoff and the Connection Block.
This anti-low temperature environment oil radiator that the utility model relates to only needs former radiator system is installed a bypass line, and with the valve port place that flow control valve is installed this bypass line, during high temperature, this bypass line is obstructed; During low temperature, this bypass line can make the oil in the former radiator flow out from bypass line, directly enters equipment needed thereby.
Description of drawings
Fig. 1 is the anti-low temperature environment oil radiator of the utility model structure chart;
Fig. 2 is the structure enlarged drawing of flow control valve;
Mark is as follows among the figure: the 1-bypass line; The 2-mount pad; The 3-oil inlet pipe; The 4-flowline; The 5-radiator fin; 6-the first valve port; 7-the second valve port; The 8-flow control valve; The 83-spool; The 84-shutoff; The 85-push rod; The 86-temperature sensor; The 87-spring; The 88-gasket seal; The negotiable zone of 89-.
Arrow among the figure represents the direction that oil flows in pipeline.
The specific embodiment
Shown in Fig. 1-2, described radiator has oil inlet pipe 3, flowline 4 and radiator fin 5, is provided with bypass line 1 between oil inlet pipe 3 outlets and flowline 4 outlets, and described bypass line 1 directly connects the oily equipment that needs; Namely the second valve port 7 is arranged the first valve port 6, the first valve ports 6 corresponding sections with oil inlet pipe 3 outlets on the bypass line 1, this valve port connection traffic control valve 8, spool 83 is located in the oil inlet pipe exit.
Described flow-control 8 valves comprise mount pad 2, spool 83, temperature sensor 86, spring 87 and shutoff 84;
Spool 83 is column, and spring 87 is enclosed within spool external compression spring 87,
Shutoff 84 is barrel-shaped, and sidewall has external screw thread, be connected with mount pad 2 internal threads, temperature sensor 86 since the elastic force effect top set of spring 87 in shutoff 84.
Spool 83 1 ends have shoulder, and spring 87 is stuck in shoulder;
The other end of spool 83 has radial slot.
Has gasket seal between shutoff 84 and the Connection Block 2.
As shown in Figure 1, be the unimpeded structure graph of the utility model flow control valve low temperature.Have among the figure and can find out, negotiable regional 89 maximums under this state are when the temperature sensor sense temperature is low, and the temperature sensor push rod contracts in temperature sensor.Under the low-temperature condition, oil mobility is very poor in the oil circuit, by bypass line, the oil in original oil circuit is drawn, and enters work system.
As shown in Figure 2, be the utility model flow control valve alternating temperature half-pass structure graph; As can be seen from the figure, when temperature raise to some extent, negotiable regional 89 under this state diminished, and namely the oily circulation of this moment is less, and the overhang of temperature sensor push rod from temperature sensor is larger.This moment, temperature raise to some extent, and the oil mobility in the oil circuit is better, and a part of oil can normally enter work system by original oil circuit, and another part can directly enter work system by the oil pipe in the bypass line.
As shown in Figure 3, be the utility model flow control valve high temperature closure structure graph; As can be seen from the figure, under this state negotiable regional 89 is zero, the overhang of temperature sensor push rod from temperature sensor is maximum, promote slip cap, and then Compress Spring, slip cap realizes that with the complete shutoff of the first valve port the oil that has good fluidity in the oil circuit enters work system by original oil circuit under the condition of high temperature.
This anti-low temperature environment oil radiator that the utility model provides, simple in structure, need not existing radiator is carried out large-scale transformation, only need install a bypass line additional, flow control valve is installed again, along with the variation of temperature, realize flow-control.Have at oil under the condition of high temperature of good fluidity, bypass line is closed under the control of flow control valve, does not affect the normal operation of existing equipment, and is convenient and swift, saves cost.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
