Abstract
A foaming plug for sealing a water tank of a solar water heater is provided with a rear end pull body, a rear end elastic ring body, a front end pull body and a front end elastic ring body which are all arranged on the base body, wherein the contact surface of the rear end pull body and the rear end elastic ring body is a tapered surface, the same as that of the front end pull body and the front end elastic ring body. When the foaming plug is used, the pull bodies extrude the elastic ring bodies to clamp the inner container and the housing of the water tank, since the inner container and the housing of the water tank are clamped and positioned by the foaming plug for sealing the water tank of a solar water heater, the thickness at the hole of the tank can not become smaller when the thermal insulation layer receives foam expansion, which is beneficial for the integral thermal insulation effect of the water tank.
Description
Technical field
The utility model relates to a kind of solar water heater tank seal foaming bung.
Background technology
At present, solar water heater tank seal foaming bung is the sealing tool that uses when being used for solar water heater water tank production process heat-insulating layer foaming, during use, foaming bung is inserted from the hole on the tank shell, its front portion is entered in the hole of inner water tank, pull the spanner of foaming bung rear end, make foaming bung expand to reach the purpose in the hole in the clamping inner water tank, form the sealing anchor ring at inner bag hole place, thus when reaching insulating foam layer with the purpose of hole sealing.But its shortcoming is: the hole that foaming bung has only clamped inner water tank does not clamp the hole on the tank shell, this just makes when insulating foam layer, because the expansion of heat-insulation layer produces a pulling force to tank shell, the hole that lacks the tank shell of insulation material is influenced by its two side draw and is out of shape, cause the tank shell and the attenuation of inner bag thickness at hole place, thereby reduced the water tank heat preserving effect.
Summary of the invention
When using, existing foaming bung causes the heat-insulation layer attenuation of water tank hole place in order to overcome, reduce the deficiency of water tank heat preserving effect, the utility model provides a kind of solar water heater tank seal foaming bung, the deficiency of water tank hole place's heat-insulation layer attenuation when this solar water heater tank seal foaming bung can solve heat-insulating layer foaming effectively.
The technical scheme that its technical problem that solves the utility model adopts is: the hinged deflection set lever in the rear end of the pull rod shaft of solar water heater tank seal foaming bung, pull rod shaft runs through baffle successively from its rear end to front end, the rear end cock body, the spacing cock body, limiting plate, baffle plate, front end elasticity circle body and front end draw body, positioning screw cap is fixed on the top of pull rod shaft, rear end cock body and spacing cock body are connected, in the gap of rear end cock body and spacing cock body, be provided with a rear end and draw body, the rear end draws body to run through a rear end elasticity circle body between rear end cock body and spacing cock body, and it is a taper surface that the contact-making surface of body and rear end elasticity circle body is drawn in the rear end, have at least a guide post one end and a rear end of passing the spacing cock body to draw body to be connected, the other end and limiting plate are connected, limiting plate is positioned at the shaft shoulder path place of pull rod shaft and is in the cavity of spacing cock body, baffle plate is positioned at the shaft shoulder place, big footpath of pull rod shaft and is in the cavity of spacing cock body, baffle plate and spacing cock body are connected, one end of front end elasticity circle body is positioned at the cavity of spacing cock body and contacts with baffle plate, and the other end of front end elasticity circle body draws body to contact with front end and contact-making surface is a taper surface; A kind of improvement project is in the above-mentioned technology: a compression spring one end is set contacts with the rear end cock body, the other end contacts with limiting plate; One end of another root compression spring contacts with baffle plate, and the other end draws body to contact with front end; Another kind of improvement project is in the above-mentioned technology: radially be provided with exhaust trench at the outer surface of rear end elasticity circle body.During use, solar water heater tank seal foaming bung is inserted from the hole on the tank shell, its front portion is entered in the hole of inner water tank, pull the deflection set lever, thereby make the rear end draw the hole in the body pushing rear end elastic ring volume expansion clamping inner water tank, form the sealing anchor ring at place, inner bag hole, also make front end draw the volume expansion of body pushing front end elastic ring to reach the purpose that clamps tank shell, thereby make all clamped location of inner water tank and shell, guarantee the not attenuation of thickness at water tank hole place with this, and the insulation layer thickness at hole place just equals the length of spacing cock body.
The beneficial effects of the utility model are: because inner water tank and shell are all by the solar water heater tank seal foaming bung clamping and positioning, guarantee the not attenuation of thickness at water tank hole place and equaled the length of spacing cock body, thereby helped the integral heat insulation effect of water tank.
