Abstract
The invention discloses a paraffin temperature sensing valve which comprises a sensing device; the sensing device comprises a housing with a cavity, a sealing cover, an ejector rod, a rubber tube, paraffin, a limit spring and an end cover; the paraffin and the rubber tube are both arranged in the cavity of the housing; the paraffin is positioned in a cavity formed by the rubber tube and the housing; the sealing cover is fixed on the housing, and seals the cavity of the housing; the rubber tube is propped against the sealing cover; one end of the ejector rod is inserted into the rubber tube in a penetrating manner; the other end of the ejector rod passes through the sealing cover to be fixed with the end cover; the housing is propped against the end cover; the limit spring sleeves the housing. The paraffin temperature sensing valve is simple in structure, and is accurate in reaction.
Description
Technical field
The present invention relates to temperature-sensing valve technical field, particularly relate to a kind of paraffin temperature-sensing valve.
Background technique
Temperature-sensing valve is usually used on motor, for lowering the temperature to the waste gas of motor, to improve the charging efficiency of motor.But at present conventional temperature-sensing valve complex structure, easily occurs error, when temperature does not also arrive predefined value, temperature-sensing valve just opens.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of structure simple, respond to paraffin temperature-sensing valve accurately.
For solving the problem, the invention provides one: described paraffin temperature-sensing valve comprises sensing device, described sensing device comprises the housing of band cavity, sealing cover, push rod, sebific duct, paraffin, limit spring and end cap, described paraffin and sebific duct are all located in the cavity of described housing, described paraffin is positioned at the cavity of sebific duct and shell combination formation, described sealing cover is fixing on the housing, by the cavities seals of its housing, described sebific duct and described sealing cover inconsistent, one end of described push rod is interted in described sebific duct, the other end of described push rod is fixed through sealing cover and described end cap, described housing and described end cap inconsistent, described limit spring is on the housing sheathed.
Further, the opening of described housing inwardly.
Further, described housing and the inconsistent the other end of described end cap are provided with groove, and described groove is used for and buckle limit spring.
Further, described housing is copper housing.
Further, described end cap is provided with the blind hole matched with push rod, and described end cap and the inconsistent the other end of described housing are provided with cylindrical projection.
Gypsum temperature-sensing valve of the present invention utilizes paraffin expanded by heating, and the active force because of push rod makes its housing move, and structure is simple; And paraffin just starts to dissolve at about 60 DEG C, just can expand after dissolving, avoid and do not reach the valve that preset temperature just opens temperature-sensing valve, make it respond to more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of gypsum temperature-sensing valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the better embodiment of gypsum temperature-sensing valve of the present invention comprises sensing device, described sensing device comprises the housing 1 of band cavity, sealing cover 2, push rod 3, sebific duct 4, paraffin 5, limit spring 6 and end cap 7, described paraffin 5 and sebific duct 4 are all located in the cavity of described housing 1, described paraffin 5 is positioned at the cavity that sebific duct 4 and housing 1 are combined to form, described sealing cover 2 is fixed on described housing 1, by the cavities seals of its housing 1, described sebific duct 4 is inconsistent with described sealing cover 2, one end of described push rod 3 is interted in sebific duct 4, the other end of described push rod 3 is fixed through sealing cover 2 and described end cap 7, described housing 1 is inconsistent with described end cap 7, described limit spring 6 is set on described housing 1, limit spring 6 is for resetting.
The opening of described housing 1 inwardly, prevents from sealing cover 2 to come off; Described housing 1 the other end inconsistent with described end cap 7 is provided with groove, and described groove is used for and buckle limit spring 6.Described housing 1 is copper housing, and copper housing heat transfer efficiency is higher, reacts quicker.
Described end cap 7 is provided with the blind hole matched with push rod 3, and described push rod 3 is fixed in blind hole.Described end cap 7 the other end inconsistent with described housing 1 is provided with cylindrical projection, is convenient to be affectedly bashful end cap 7 when safeguarding.
When paraffin 5 expanded by heating, because push rod 3 and end cap 7 are fixed, push rod 3 cannot move, and the reaction force that therefore housing 1 is subject to its push rod 3 makes its housing 1 move, and housing 1 promotes valve open, and structure is simple.And paraffin 5 just starts to dissolve at about 60 DEG C, just can expand after dissolving, avoid and do not reach the valve that preset temperature just opens temperature-sensing valve, make it respond to more accurate.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing specification of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
