In this embodiment, the low boiling point temperature sensing material 170 is in a liquid state, and its volume may fill the accommodating space 130 between the upper cover 110 and the protruding portion 121 of the lower cover 120, or may occupy only a part of the volume of the accommodating space 130. The low boiling point temperature sensing material 170 is a chemical material which is stable in chemical property and has little corrosion to metals, and is preferably any one or a mixture of a plurality of acetone, methanol, n-pentane and methylene dichloride. Which material is specifically selected is selected according to the requirements of the actual alarm temperature. Or a mixture of any two or three or four of the above materials can be selected, and the specific proportion is prepared according to actual needs.
Preferably, in the present embodiment, a groove 123 is provided at the top of the protruding portion 121 of the lower cover 120, the groove 123 is at least a part of the accommodating space 130, so that the low boiling temperature sensing material 170 in an original liquid state is contained in the groove 123, on one hand, the low boiling temperature sensing material 170 in an original liquid state can be prevented from seeping out from the joint portion between the protruding portion 121 of the lower cover 120 and the upper cover 110, on the other hand, the low boiling temperature sensing material 170 is closer to the bottom of the cover 100, and the low boiling temperature sensing material 170 can more accurately and more rapidly receive the heat transferred by the liquid containing container and the internal liquid. Therefore, the width and depth of the recess 123 may be designed according to the actual amount of the low boiling point temperature sensing substance 170.
Further, the case cover 100 may further include a sealing ring 150, at least one annular clamping groove (not shown in the drawing) is disposed on an outer side wall of the protruding portion 121 of the lower cover 120, the number of the sealing rings 150 is set corresponding to the number of the annular clamping grooves, and one sealing ring 150 is just sleeved in one annular clamping groove, so as to improve tightness of the accommodating space 130 between the upper cover 110 and the protruding portion 121 of the lower cover 120.
Referring to fig. 1 and 2, in the present embodiment, an annular clamping groove is preferably disposed at the top of the protruding portion 121 of the lower cover 120, that is, the periphery of the top of the groove 123 at the top of the protruding portion 121 of the lower cover 120, and the sealing ring 150 is clamped in the annular clamping groove to perform a sealing function better.
The sealing ring 150 may be a rubber ring with high smoothness and certain elasticity, or may be made of other commonly used valve pressure-resistant sealing ring 150.
It will be appreciated that the indicia 140 are provided for purposes of determining that the temperature of the liquid holding container and the liquid therein reaches or exceeds the temperature to be pre-warned; when the temperature of the liquid container and the liquid in the liquid container reaches or exceeds the temperature to be pre-warned, the low boiling temperature sensing material 170 in the case cover 100 is vaporized in the closed accommodating space 130 to form saturated vapor pressure, and the upper cover 110 is pushed to move upwards, so that the arranged mark 140 is exposed and found by the staff. The mark 140 may be a common text or pattern mark, and only needs external light to enable the staff to visually observe.
In this embodiment, the indicia 140 is preferably a luminescent coating so that it is easily noticeable to the operator at night without ambient light or light darkness. The luminescent coating can be obtained by spraying a mixture of fluorescent powder and paint on the outer side wall of the protruding part 121 of the lower cover 120 and drying or naturally airing, and meanwhile, the paint is bright-colored paint such as yellow, red, green and other colors, so that the fluorescent coating can be more noticeable in the daytime or at night, and can be more easily and quickly noticed by staff; the luminescent coating can also be prepared by mixing rare earth and varnish, wherein the rare earth is alkaline earth aluminate which has the characteristics of light storage and light release. Of course, other existing luminescent coatings can be used as the luminescent coating material. The luminous coating can be designed into any pattern, so that the effect of temperature early warning is achieved, and the effect of beautifying is achieved.
Further, in this embodiment, a varnish coating layer or a transparent wear-resistant layer may be further coated on the outer surface of the luminescent coating layer, so as to improve the glossiness, wear resistance and durability of the luminescent coating layer, and avoid the luminescent coating layer from falling off after a long time. Of course, the part of the outer side wall of the protruding portion 121 of the lower cover 120, on which the luminescent coating is sprayed, may be roughened in advance, so as to increase the adhesion of the luminescent coating on the outer side of the protruding portion 121 of the lower cover 120, and further prevent the luminescent coating from falling off from the protruding portion 121 of the lower cover 120 due to a long time. And a reflective material can be added on the luminous coating, so that the reflection formed at night under the irradiation of external light can be more easily found. In addition, in order not to affect the upper cover 110 to slide up and down along the protrusion 121 of the lower cover 120, the thickness of the luminescent coating layer should be as thin as possible and the surface should be smooth.
It should be noted that, when the case cover 100 of the present embodiment is applied to a liquid container, such as a radiator tank or an engine oil tank, when the temperature of the liquid container and the internal liquid reaches or exceeds the temperature to be pre-warned, the low boiling temperature sensing material 170 in the case cover 100 is vaporized to reach the vaporization temperature, so that the saturated vapor pressure is formed in the sealed accommodating space 130, thereby pushing the upper cover body 110 to move upwards, so that the light-emitting coating provided on the outer side wall of the protruding portion 121 of the lower cover body 120 is exposed, as shown in fig. 1, even if a worker easily discovers the light-emitting coating at night, thereby realizing the temperature pre-warning function of the case cover 100, warning the worker that the temperature of the liquid container and the internal liquid is high at this time, and the worker is not suitable for touching operation; when the temperature of the liquid container and the liquid inside the container does not reach the temperature to be pre-warned, i.e. the temperature is in a normal state, the low boiling temperature sensing material 170 is not vaporized to be in an original liquid state, and the luminous coating arranged on the outer side wall of the protruding portion 121 of the lower cover 120 is shielded by the upper cover 110, as shown in fig. 2, which indicates that the worker can perform the touching operation at this time.
Further, referring to fig. 1 and 2, in the present embodiment, the case cover 100 further includes an elastic member 160, the elastic member 160 is disposed between the protruding portion 121 of the lower cover 120 and the upper cover 110, one end of the elastic member 160 is connected to the top of the protruding portion 121 of the lower cover 120, and the other end of the elastic member 160 is connected to the upper cover 110. The elastic member 160 may be a spring or a spring piece.
The elastic member 160 may be detachably connected to the top of the protrusion 121 of the lower cover 120, or may be non-detachably connected to the top of the protrusion 121, and similarly, the elastic member 160 may be detachably connected to the upper cover 110, or may be non-detachably connected to the top of the protrusion 121. For example, the detachable connection may be: a clamping seat is arranged at the top of the protruding part 121 of the lower cover 120, and one end of the elastic part 160 is detachably arranged on the clamping seat through a buckle; a hanging ring is provided at the top of the upper cover 110, and a hook is provided at the other end of the elastic member 160 to hang the hanging ring.
It should be noted that, in this embodiment, by providing the elastic member 160 between the top of the protruding portion 121 of the lower cover 120 and the upper cover 110, on one hand, the upper cover 110 is prevented from being pushed away from the lower cover 120 due to the excessively high saturated vapor pressure formed by vaporization of the low boiling temperature sensing material 170, on the other hand, when the temperature of the liquid container and the internal liquid is reduced, the saturated vapor pressure in the accommodating space 130 between the upper cover 110 and the lower cover 120 is reduced, and when the temperature of the liquid container and the internal liquid is reduced below the predetermined warning temperature, the spring starts to shrink and recover to the original state, so as to drive the upper cover to slowly move downwards, and automatically recover to the original state, and compared with the case that the upper cover 110 is allowed to fall to recover to the original state by only gravity, the upper cover 110 is more stable and has higher reliability.
In this embodiment, the elastic member 160 is preferably a spring, and the number of the springs may be 1, one end of the spring is connected to the middle of the top of the protruding portion 121 of the lower cover 120, and the other end of the spring is connected to the middle of the top of the inner side of the upper cover 110; the number of springs may be 2, 3, 4 or more, and the springs may be symmetrically disposed between the top of the protruding portion 121 of the lower cover 120 and the upper cover 110, for example, one end of each spring may be connected to the top of the protruding portion 121 of the lower cover 120, and the other end may be connected to the top of the inner side of the upper cover 110, or may be connected to the inner side wall of the upper cover 110, so that the whole stress is uniform.
Further, in the present embodiment, a baffle (not shown) may be provided near the periphery of the bottom of the cover plate 122 of the lower cover 120, so as to prevent the cover 100 from sliding off when the cover is not smooth and directly covering the water inlet of the liquid container such as radiator tank; the baffle may be designed as an annular baffle around the bottom of the cover plate 122 of the lower cover 120 near the outer periphery, or may be designed such that 2, 3 or 4 small baffles are uniformly disposed around the bottom of the cover plate 122 of the lower cover 120 near the outer periphery.
Of course, the bottom of the case cover 100 may be designed according to the inlet of the corresponding liquid container, for example, when the inlet has an external thread, a recess having an internal thread matching the external thread may be designed at the bottom of the case cover 100.
It should be noted that, the longitudinal section of the lower cover 120 is not limited to the convex structure of the present embodiment, for example, the longitudinal section of the lower cover 120 may be also in a chevron shape, the upper cover 110 may just cover the middle protrusion of the chevron-shaped lower cover 120, the inner side wall of the upper cover 110 and the outer side wall of the middle protrusion of the lower cover 120 are in contact with each other in a sliding manner, and a closed accommodating space 130 for accommodating the low boiling temperature sensing material 170 is provided between the inner side wall of the upper cover 110 and the middle protrusion of the lower cover 120; for example, the longitudinal section of the lower cover 120 may be in a concave structure, the upper cover 110 is covered on the concave lower cover 120, the inner side wall of the upper cover 110 is in contact with the outer side wall of the concave lower cover 120, and the closed concave cavity between the concave lower cover 120 and the upper cover may be used as the accommodating space 130 for accommodating the low boiling temperature sensing material 170.
Of course, the longitudinal section of the upper cover 110 is not limited to the inverted U-shaped structure, and for example, the longitudinal section of the upper cover 110 may be pi-shaped structure.
