Abstract
The invention discloses a thermostat seat for an engine. The thermostat seat comprises a thermostat seat body, wherein a valve seat for a thermostat to be installed is formed at the upper end of the thermostat seat body, and a limiting groove for positioning the thermostat and preventing the thermostat from being installed inversely is formed in the position, close to the valve seat, of the inner wall of the thermostat seat body. The end face of the valve seat upwards protrudes to form a sealing rib matched with an outer sealing part of the thermostat for sealing. After the thermostat is arranged on the valve seat, the thermostat installing direction can be judged and the thermostat can be limited through the limiting groove formed in the thermostat seat body, so that the thermostat has the quick installing effect and is prevented from being installed inversely, convenience is brought to an exhaust valve on the thermostat to discharge air in a cooling water way, and the sealing performance of the bonding surface is ensured. In addition, the sealing rib arranged on the valve seat and the outer sealing part of the thermostat can play a joint role for sealing, the sealing effect is good, and sealing failure is prevented. The thermostat seat is simple in structure and convenient to use and has better application prospect.

Further, the bowl configurations that is recessed to form laterally by thermostat base inner body wall of restraining groove.
Further, the thermostat base body opposite valve seat the other end forms cylinder cap connecting end, described cylinder cap connecting end is embedded with the seal ring for sealing.
Further, seal ring comprises main body portion and the one-body molded and limited part extended radially outwardly with main body portion, described cylinder cap connecting end being formed with the mounting groove of the main body portion for installing seal ring, being formed through with described mounting groove radial direction the opening slot snapped in for limited part.
Further, the main body portion of seal ring stretches out described mounting groove vertically.
Further, thermostat base body sidewall nearly valve seat end is also provided with inner space and for temperature sensor mounted mounting hole.
Further, thermostat base body is positioned at the one-body molded fitting seat be formed with for fixed temperature sensor of mounting hole outer fix, fitting seat comprises inner position portion and outside fix portion, forms the draw-in groove engaged for the jump ring of fixed temperature sensor between described inner position portion and described outside fix portion.
Beneficial effect of the present invention: motor thermostat base of the present invention, be seated at after on valve seat at thermostat, can judge the installation direction of thermostat by the restraining groove that thermostat body is arranged and thermostat be formed spacing, envoy's temperature utensil has quick mounting effect, and thermostat can be prevented anti-loaded, and to be conducive on thermostat outlet valve to air venting in cooling water channel, ensure junction plane sealing, the sealed muscle simultaneously valve seat arranged can seal with the outside seal acting in conjunction of thermostat, good sealing effect, prevents seal failure; Structure of the present invention is simple, easy to use, has good application prospect.
