Description of the drawings
In order that content of the present utility model is more likely to be clearly understood, it is embodied as below according to of the present utility model
Example simultaneously combines accompanying drawing, and this utility model is described in further detail, wherein,
Fig. 1 is the structural representation of control valve described in the utility model；
In figure, reference is expressed as：1- valve blocks, 2- oil inlet passages, the first oil discharge passages of 3-, the second oil discharge passages of 4-, 5-
First gear part, 6- paraffin thermometer bulbs, 7- elastomeric elements, 8- retractable member, 9- valve gaps, 10- the second gear parts.
Specific embodiment
Structure as shown in Figure 1, lubrication paraffin thermometer bulb control valve described in the utility model are mainly used in gear-box
Or the lubrication oil cooling of fuel tank is used.The control valve includes valve body 1, and the valve block 1 forms oil inlet passage 2 and first goes out
Oily passage 3, the second oil discharge passage 4, first oil discharge passage 3 are connected with work equipment, second oil discharge passage 4 with it is cold
But device is connected and loop is connected to the work equipment.The oil inlet passage 2 respectively with first oil discharge passage 3 and described
Second oil discharge passage, 4 perpendicular setting；And second oil discharge passage 4 is located at below first oil discharge passage 3 closer to institute
State at 2 position of oil inlet passage.First oil discharge passage 3 is connected with the oil inlet passage 2 respectively with second oil discharge passage 4
Lead to but do not connect each other.The lubricating oil enters the oil inlet passage 2 from below, by the control of the control valve,
So that the lubricating oil flow to gear-box from first oil discharge passage 3, or it is cold from second oil discharge passage 4 outflow Jing
But gear-box is back to again after device cooling.
As shown in figure 1, control valve described in the utility model is felt by the paraffin thermometer bulb 6 being arranged in the oil inlet passage 2
Know the temperature regime of the fluid of entrance, and then expand or shrink, to drive the motion of miscellaneous part so that the oil-feed is led to
Obtain second oil discharge passage 4 respectively with first oil discharge passage 3 and be connected or close in road 2.
The paraffin thermometer bulb 6 is mutually fixedly connected with the valve gap 9 of the valve block 1 by retractable member 8, so with the valve
Block 1 is mutually fixed.The paraffin thermometer bulb 6 is expanded and drives the connected retractable member by perceiving oil liquid temperature change
8 motions, and then it is fuel-displaced with described first to drive the switching device being arranged in the oil inlet passage 2 to control the oil inlet passage 2
Passage 3 is connected and closure with second oil discharge passage 4.Herein, the retractable member 8 is set to scalable push rod.
Structure as shown in Figure 1, the switching device include the first gear part 5 being connected with the paraffin thermometer bulb 6,
And the second gear part 10 of elastomeric element 7 is fixedly connected with, the paraffin thermometer bulb 6 is mutually compressed with the elastomeric element 7 matches somebody with somebody
Close；The first gear part 5 with the retractable member 8 motor control described in oil inlet passage 2 it is fuel-displaced with described first
The connection of passage 3 or closure, the second gear part 10 drive the elastomeric element 7 with the expansion of the paraffin thermometer bulb 6
Connection or the closure of oil inlet passage 2 described in compression control and second oil discharge passage 4.
In this utility model, the first gear part 5 is set to valve pocket, and with 6 phase interference fit of the paraffin thermometer bulb
Connection.The second gear part 10 is the tubular baffle plate coaxial with the oil inlet passage 2, and its inwall is fixedly connected with the bullet
Property part 7, and the apical position flush of the top of the second gear part 10 and second oil discharge passage 4.The bullet
Property part 7 be then connected with the valve pocket compression, and as the motion of the valve pocket is compressed downwards, to drive the institute being secured to
State the second gear part 10 to move downward so that second oil discharge passage 4 is connected lubricating oil with the oil inlet passage 2
Lower the temperature in importing cooler.
Lubrication paraffin thermometer bulb control valve principle described in the utility model and the course of work are as follows：Gear box lubricating oil by
Shown inflow pipeline 2 is entered in the control valve, originally when oil temperature is relatively low, and fluid is entered after valve inner from inflow pipeline 2,
Whole valve pocket is headed on due to there is the elastomeric element 7 to support, now, due to the top and described the of the second gear part 10
Two oil discharge passages, 4 flush, causes second oil discharge passage 4 to be closed, and first oil discharge passage 3 is then logical with the oil-feed
Road 2 is connected so that fluid can not enter the second oil discharge passage 4, can only enter the first oil discharge passage 3, that is, be directly communicated to gear-box.
As the paraffin thermometer bulb 2 is a kind of temperature-sensing element, when the temperature for setting is reached, the scalable push rod above thermometer bulb can be because
Expansion inside thermometer bulb and extend, integrated pushing valve pocket and paraffin thermometer bulb 6 are moved downward, and valve pocket compresses the elastomeric element fortune
It is dynamic so that now elastomeric element 7 is compressed, and the side wall of valve pocket is moved downward so that first oil discharge passage is closed；And institute
Stating elastomeric element 7 is driven tubular baffle plate to move downward by compression so that opened by the second oil discharge passage 4 that baffle plate is closed originally,
So that oil inlet passage 2 is connected with the second oil discharge passage 4, and and then fluid is lowered the temperature into cooler.This utility model institute
The purpose for stating control valve is the fluid stream when oil temperature set in advance is reached in order to oil temperature is raised rapidly after machinery equipment cold start-up
Lower the temperature to switching through cooler, such oil temperature is remained in certain zone of reasonableness.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And thus it is extended obvious change or
Among changing still in the protection domain of the invention.
