Abstract
The utility model relates to a thermostat, which is composed of a casing, a valve rod, a top valve, an auxiliary valve, etc. The utility model is characterized in that the casing is provided with a biasing spring which is a pressure spring structure, the biasing spring is sheathed on the valve rod, both ends are respectively restricted by the top valve, and the casing and the spring seat of the bottom; the outer part of the casing is provided with a memory alloy spring which is also a pressure spring structure, the memory alloy spring is sheathed at the lower end of the valve rod, both ends are respectively restricted by the auxiliary valve and the spring seat. The utility model has the advantages of simple structure and reliable performance.
Description
The utility model relates to valve body, and a kind of thermostat that is used for automobile engine system is provided especially.
Thermostat is the parts in the automobile engine system, and its function is the temperature of regulating the engine cycles cooling water, to guarantee that internal-combustion engine is through the work under the optimum temperature state of being everlasting.Commonly used is waxtype thermostat at present, and temperature sensing material is extraordinary paraffin.Liquefaction by paraffin rises the overhead-valve that opens thermostat, makes cooling water flow through radiator heat-dissipation, and the circulation of the radiator of flowing through claims major cycle again, otherwise claims short circle.The water temperature of cooling water is regulated by thermostat, and the heat of the hot parts water that is cooled is taken away and shed by radiator, and internal-combustion engine can be not overheated.The shortcoming of waxtype thermostat is a complex structure, the manufacture process requirement height, and easily leak, cause thermostat to lose efficacy.
The purpose of this utility model provides a kind of simple in structure, the thermostat of reliable performance.
The utility model provides a kind of thermostat, is made up of housing (1), valve rod (2), overhead-valve (3), secondary valve parts such as (4); It is characterized in that: (a) housing (1) inside is equiped with bias spring (5), is the stage clip structure, and it is placed on the valve rod (2), and two ends are respectively overhead-valve (2) and housing (1), the spring seat of bottom (13) constraint; (b) housing (1) outside is equiped with memory alloy spring (6), also is the stage clip structure, and it is placed in valve rod (2) lower end, and two ends are respectively by secondary valve (4) and spring seat (13) constraint.Housing (1) is connected as a single entity with spring seat (13), is made by brass material; Memory spring adopts niti-shaped memorial alloy to make material.Simple in structure, reliable, by embodiment in detail the utility model is described in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the thermostat stereogram;
Accompanying drawing 2 is the thermostat sectional view.
Embodiment
As Fig. 1, shown in 2: mainly form by housing (1), valve rod (2), overhead-valve (3), secondary valve (4), housing (1) is made of the valve rod constraint sheet (11) at top, the flange plate (12) at middle part, the spring seat (13) of bottom, use armed lever (112), (123) to connect therebetween respectively, constraint sheet (11) and spring seat (13) are gone up with holes respectively, and flange plate (12) internal diameter is connected to one and makes progress and inside cone flank wall (121); Overhead-valve (3) is installed in housing (1) inside; Valve rod (2) passes housing (1) and overhead-valve (3), and spring seat (13) one ends and secondary valve (4) are fixing; Bias spring (5) is contained in valve inner, and its two ends are retrained by overhead-valve (3) and spring seat (13) respectively, and memory spring (6) is contained in the valve body outside, and its two ends are retrained by secondary valve (4) and spring seat (13) respectively.Overhead-valve (3) and secondary valve (4) are connected as a single entity with valve rod (2), and overhead-valve (3) and secondary valve (4) match by two springs and move.When water temperature was lower than 70 ℃, memory alloy spring (6) was in compressive state, and thermostat overhead-valve this moment (3) cuts out cooling water without radiator, flowed through short circle.When temperature surpasses 70 ℃, memory alloy spring (6) beginning elongation gradually, and generation power, this makes every effort to overcome the power of clothes bias springs (5), drives valve rod (2) and moves down, and overhead-valve (3) is opened gradually.A cooling water part is located the radiator of flowing through through overhead-valve (3), and another part cooling water carries out short circle.When water temperature surpassed 80 ℃, overhead-valve (3) was all opened, and cooling water carries out major cycle.This moment high temperature in addition the heat of the part water that is cooled take away, shed by radiator, internal-combustion engine can be not overheated.When if water temperature is lower than 70 ℃, memory alloy spring (6) shrinks, and under the effect of spring (5) power, overhead-valve (3) cuts out fully, and cooling water all carries out short circle.So return again, utilize the elongation of height memory alloy spring (6) of water temperature and the keying that overhead-valve is controlled in compression, thereby guarantee that internal-combustion engine moves under the optimum temperature situation of being everlasting.
Claims (2)
1. a thermostat is made up of housing (1), valve rod (2), overhead-valve (3), secondary valve parts such as (4); It is characterized in that:
(a) housing (1) inside is equiped with bias spring (5), is the stage clip structure, and it is placed on the valve rod (2), and two ends are respectively overhead-valve (2) and housing (1), the spring seat of bottom (13) constraint;
(b) housing (1) outside is equiped with memory alloy spring (6), also is the stage clip structure, and it is placed in valve rod (2) lower end, and two ends are respectively by secondary valve (4) and spring seat (13) constraint.
2. by the described thermostat of claim 1, it is characterized in that: housing (1) is made by brass material, and memory spring is adopted with niti-shaped memorial alloy and made material.
