Background technology
Solar water heater generally is positioned at the roof of buildings, need special device that its water-temperature water-level is monitored, present water-temperature water-level sensor mainly includes hollow barred body, sensing head, temperature sensitive member, the water-temperature water-level sensor of water level detecting element and lead, because it adopts hollow-core construction, insulating material all is to adopt heat-shrink tube or plastic material, heat shrinkable pipe material is used in insulating material and conductive electrode sealing, inner filling fluid sealant carries out waterproof, owing to exist the high low temperature ageing resistance of parts poor, cause infiltration easily, thereby after long-time the use, the water capacity easily is penetrated into barred body inside and makes electric pole short circuit, accurate sensed water level, thus sensor performance influenced.
Summary of the invention
The purpose of this utility model provides a kind of water-temperature water-level sensor that can effectively improve sealing property.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises insulator cap, conductive electrode, insulated connecting piece, the water level detecting element, temperature sensitive member and interface web member, temperature sensitive member is located at conductive electrode inside, the interface web member is sleeved on the conductive electrode, described conductive electrode adopts segmental structure, the water level detecting element is located between two sections conductive electrodes, per two sections conductive electrodes are connected by an insulated connecting piece, adopt tight shell type hermetically-sealed construction between insulated connecting piece and the conductive electrode, tight shell type hermetically-sealed construction inside is provided with layer of silica gel.
Insulator cap described in the utility model and insulated connecting piece are that ceramic material forms.
The said structure that the utility model adopts adopts tight shell type sealing between insulating material and the conductive electrode, inner filling gel layer carries out waterproof sealing, has improved sealing property; Insulating material adopts industrial ceramics, and high temperature resistant 1000 ℃, low temperature-60 ℃ are indeformable, aging.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
1 insulator cap, 2 conductive electrodes, 3 insulated connecting piece, 4 water level detecting elements, 5 temperature sensitive member, 6 interface web members in the drawings
Embodiment
By accompanying drawing as can be known, this water-temperature water-level sensor comprises insulator cap 1, conductive electrode 2, insulated connecting piece 3, water level detecting element 4, temperature sensitive member 5 and interface web member 6, temperature sensitive member 5 is located at conductive electrode 2 inside, interface web member 6 is sleeved on the conductive electrode 2, described conductive electrode 2 adopts segmental structure, water level detecting element 4 is located between two sections conductive electrodes, per two sections conductive electrodes are connected by an insulated connecting piece 3, adopt tight shell type hermetically-sealed construction between insulated connecting piece 3 and the conductive electrode 2, tight shell type hermetically-sealed construction inside is provided with layer of silica gel.Insulator cap 1 described in the utility model and insulated connecting piece 3 form for ceramic material.Stupalith adopts industrial ceramics, can high temperature resistantly reach 1000 ℃, low temperature resistant reaching-60 ℃.During use, sensor is upwards inserted water tank inside from the bottom of solar water heater water tank, the interface web member of its bottom links to each other with the tank entry sealing.Because conductive electrode is a stainless steel metal pipe, do not have flexibility, so it after inserting water tank inside, water tank bottom remains straight up, and height that so just can accurate sensing water level guarantees its operate as normal.Filling gel layer in the tight shell type hermetically-sealed construction of conductive electrode can further strengthen the sealing that is connected between conductive electrode and each water level detecting element, the stability and the serviceable life of assurance working sensor.
