Abstract
The invention relates to the field of diesel engine equipment, in particular to a thermostat. The thermostat comprises an enfolding airtight expansion cylinder, a lateral valve and an upper valve, wherein the lateral valve and the upper valve are arranged at the upper end of the expansion cylinder. The thermostat is characterized in that the expansion cylinder is made of brass and is filled with a diethyl ether aqueous solution, the lateral valve and a connecting rod are welded to the upper end of the expansion cylinder, the upper valve is welded to the upper end of the connecting rod, the upper valve is provided with an air hole, the expansion cylinder is sleeved with a shell, a valve seat is arranged at the upper end of the shell, the lateral valve is arranged in the valve seat, the shell is provided with a by-pass hole, and the bottom of the expansion cylinder is provided with a supporting holder. The thermostat is simple in structure and long in service life.
Description
Technical field
The present invention relates to diesel-engine equipment field, be specifically related to a kind of thermostat.
Background technique
In the cooling system of pump circulation, usually utilize thermostat to change circular flow and the range of DO of cooling water, to reach the object of automatic controlled cooling model intensity, thermostat is generally installed on cylinder head water outlet, the shortcomings such as present thermostat has complex structure, and working life is short.
Summary of the invention
For the problems referred to above, the invention provides a kind of structure simple, the thermostat of long service life.
Realize technological scheme of the present invention
Thermostat, comprise the airtight expanding cylindrical of folding type, side valve door and upper valve, side valve door and upper valve are arranged on the upper end of expanding cylindrical, expanding cylindrical is made up of brass, inside is filled with ether solution, expansion cylinder upper end is welded with side valve door and connecting rod, connecting rod upper end is welded with valve, upper valve offers vent, is set with shell outside expanding cylindrical, shell upper end is provided with valve seat, side valve door is arranged between valve seat and shell, and shell offers by-pass hole, is provided with supporting bracket bottom expanding cylindrical.
Adopt such scheme, thermostat, comprise the airtight expanding cylindrical of folding type, side valve door and upper valve, expanding cylindrical is made up of brass, inside is filled with ether solution, ether solution is easy to volatilization, expansion cylinder upper end is welded with side valve door and connecting rod, connecting rod upper end is welded with valve, shell is set with outside expanding cylindrical, shell offers by-pass hole, by-pass hole faces the bypass tube of cylinder head outlet pipe, bypass tube is connected with pump intake, in expanding cylindrical, the vapor pressure of liquid changes with environment temperature change, ancient cylinder heights also changes with temperature, when the peripheral water temperature of expanding cylindrical raises, liquid gasification in cylinder, volume increases, cylinder is made to expand and upwards extend, so upper valve is performed fighting gradually, side valve Men Ze turns down gradually.
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
In figure, 1 is expanding cylindrical, and 2 is side valve door, and 3 is upper valve, 4 connecting rods, 5 vents, 6 valve seats, and 7 is supporting bracket, and 8 is shell.
Embodiment
As shown in the figure, thermostat, comprise the airtight expanding cylindrical 1 of folding type, side valve door 2 and upper valve 3, side valve door 2 and upper valve 3 are arranged on the upper end of expanding cylindrical 1, expanding cylindrical 1 is made up of brass, corrosion resistance is high, inside is filled with ether solution, ether solution is volatile, expanding cylindrical 1 upper end is welded with side valve door 2 and connecting rod 4, connecting rod 4 upper end is welded with valve 3, upper valve 3 offers vent 5, shell 8 is set with outside expanding cylindrical 1, shell 8 upper end is provided with valve seat 6, side valve door 2 is arranged between valve seat 6 and shell 8, make side valve door 2 more fixing, shell 8 offers by-pass hole, supporting bracket 7 is provided with bottom expanding cylindrical 1, the seat of fixing thermostat, by-pass hole faces the bypass tube of cylinder head outlet pipe, bypass tube is connected with pump intake, in expanding cylindrical 1, the vapor pressure of liquid changes with environment temperature change, cylinder heights also changes with temperature, when the peripheral water temperature of expanding cylindrical 1 raises, liquid gasification in cylinder, volume increases, cylinder is made to expand and upwards extend, valve seat and shell do not move with cylinder and move, and due to connecting rod, side valve door, upper valve and cylinder are for welding, therefore, valve seat and side valve door close, connecting rod moves upward, so upper valve 3 is performed fighting gradually, 2, side valve door turns down gradually, otherwise, when the peripheral water temperature of expanding cylindrical 1 reduces, the height of cylinder shortens, distance between valve seat and side valve door is pulled open, connecting rod moves downward, valve member is turned down, side valve door assembly is opened greatly.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
