A kind of ultra-thin spool

Abstract

The invention discloses an ultra-thin valve core, and relates to the technical field of valve cores. The ultra-thin valve core includes a valve core barrel body, an air vent assembly and an air outlethole assembly, a rotating head is installed on the upper part of the interior of the valve core barrel body, and clamping grooves are formed in both sides of the rotating head; the air vent assemblypenetrates through one side of the valve core barrel body, the air outlet hole assembly penetrates through the other side of the valve core barrel body, and the air outlet hole assembly includes a fan-shaped opening, a U-shaped hole and an air outlet hole flow passage; and an installation inner cavity is internally provided with a rotating inner core, the rotating inner core is fixedly connected with the rotating head, and the middle of the rotating inner core is provided with a rotating shaft. The ultra-thin valve core has the beneficial effects that by controlling the height of the valve core barrel body, an extremely thin furnace is realized, a hearth panel does not require an opening to be inserted into the furnace, the length of the valve core barrel body is about 15-20 mm, and the length of a conventional valve core is 30-38 mm.

Description

technical field [0001] The invention relates to the technical field of valve cores, in particular to an ultra-thin valve core. Background technique [0002] The spool is an adjustment switch to adjust the flow rate of the valve assembly. The spool is divided into three types: large fire hole, conversion medium fire hole and fire protection hole. The gas in the valve assembly enters the inner hole of the valve core, and then flows to the nozzle and burner from each hole on the side of the valve core. Through the rotation angle, the size and conversion of the burner firepower can be adjusted and controlled. [0003] The existing conventional spool is 30-38 mm. During installation, the cooktop panel needs to open holes to embed the stove to ensure the installation of the conventional spool. However, when the embedded stove burns due to lack of oxygen, it is easy to produce red flames and excessive carbon monoxide. The bad phenomenon, and the four sides of the traditional embe...

Problems solved by technology

[0004] The purpose of the present invention is to provide an ultra-thin valve core to solve the problem that the conventional valve core proposed in the above-mentioned background technology is 30-38 mm. When installing, the cooktop panel needs to open a hole to embed the stove to ensure the installation of the conventional valve core. , while the built-in stove lacks oxygen when burning, it is easy to produce red flames and excessive carbon monoxide, and the force on the four sides of the traditional built-in stove is easy to cause deformation or fracture of the panel, and the ordinary valve core cannot meet the requirements. The large-angle adjustment requirements of the fierce stove series in the market, and the adjustment of large and small fires cannot be accurately realized, nor can sufficient airflow be provided to achieve large fires and large flow rates.
