Abstract
The utility model discloses a connection structure of a ceramic valve core stator and a valve core housing of a pipeline blow-off valve. The utility model comprises a ceramic valve core stator and a valve core housing. The ceramic valve core stator is provided with an air hole and a water hole, and the valve core housing is provided with an air channel and a water channel. The air hole of the ceramic valve core stator is communicated with the air channel of the valve core housing, and the water hole of the ceramic valve core stator is communicated with the water channel of the valve core housing, thereby the valve core housing and the ceramic valve core stator are fixed together through the injection, or fixedly connected together through a self-tapping screw. By using the utility model, the installation positioning of the ceramic valve core stator and the valve core housing is accurate, the sealing is reliable, the pressure cap of the stator can be saved, the installation steps can be reduced, and the assembly precision and the yield rate can be improved.
Description
Technical field
The utility model relates to a kind of exhaust-valve of solar water heater.
Background technology
Pipe line evacuation valve is generally used for the emptying of solar water heater and water up and down.The ceramic cartridge stator in the existing pipe line evacuation valve and the syndeton of spool housing are, comprise ceramic cartridge stator, stator pressure cap and spool housing, the stator pressure cap is threaded with the spool housing, the ceramic cartridge stator is pressed on the spool housing by the stator pressure cap, between ceramic cartridge stator and the spool housing sealing ring is housed also.There is following shortcoming in above structure: the assembly precision of ceramic cartridge stator and spool housing is not high, and yield rate is low, and Assembly part is many, and installation steps are loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to provide a kind of assembly precision height, the ceramic cartridge stator easy for installation and the syndeton of spool housing.
In order to achieve the above object, first kind of technical scheme of the present utility model is, the syndeton of a kind of ceramic cartridge stator and spool housing, comprise ceramic cartridge stator and spool housing, have pore and water hole on the ceramic cartridge stator, have gas passage and aquaporin on the spool housing, the pore of ceramic cartridge stator communicates with the gas passage of spool housing, the water hole of ceramic cartridge stator communicates with the aquaporin of spool housing, and described spool housing and the injection moulding of ceramic cartridge stator are fixed together.
The upper and lower edge of described ceramic cartridge stator all is coated in the spool case material.
After adopting above-mentioned first kind of technical scheme, because spool housing and the injection moulding of ceramic cartridge stator are fixed together, guaranteed that the installation location between ceramic cartridge stator and the spool housing is accurate, sealing is reliable; Economize seal and stator pressure cap, reduced installation steps, improved assembly precision and yield rate.
In order to achieve the above object, second kind of technical scheme of the present utility model is, the syndeton of a kind of ceramic cartridge stator and spool housing, comprise ceramic cartridge stator and spool housing, have pore and water hole on the ceramic cartridge stator, have gas passage and aquaporin on the spool housing, the pore of ceramic cartridge stator communicates with the gas passage of spool housing, the water hole of ceramic cartridge stator communicates with the aquaporin of spool housing, has installing hole on the described ceramic cartridge stator, tapping screw penetrates installing hole and shoots in the spool housing, and the ceramic cartridge stator is fixedlyed connected with the spool housing.
The installing hole of described ceramic cartridge stator and tapping screw are four.
After adopting above-mentioned second kind of technical scheme, because the ceramic cartridge stator is fixed on the spool housing with tapping screw, do not need machining screw on the spool housing, economized the stator pressure cap, reduced installation steps, improved assembly precision and yield rate, guaranteed that the installation location between ceramic cartridge stator and the spool housing is accurate.
