Embodiment Construction

[0016] In a sandwich pressure cooker 2 with a jacket 21 made of stainless steel, the part valve body bolt 11 of a pressure cooker one-way valve 1 is welded to the inner wall of the top of the jacket 21, with the outer surface 111 of the bolt 11 in a circle Welding makes the bolt and the inner wall of the jacket into one body, and there is no space on the outer surface of the bolt to allow the airflow to rise; and above the center of the bolt of the valve body, there is a small exhaust hole 110, correspondingly There is also a small round through hole at the top of the jacket layer corresponding to the bolt, so that the above two small holes are on the same centerline and communicate, that is, if the gas from the bolt is exhausted from the exhaust hole 110, you can It is discharged to the outside of the pot through the round through hole on the jacket.

[0017] The pressure cooker one-way valve of the present invention is composed of a valve body bolt 11, a valve body 12, a spring...

Abstract

The invention discloses a pressure cooker one-way valve, which is installed at the top part of the inner of a jacket of a jacket-mounted pressure cooker and welded to the inner wall of the jacket; the one-way valve is composed of a valve body bolt 11, a valve body 12, a spring 13 and a steel ball 14, wherein the bolt is in threaded connection with the valve body, an exhaust hole is arranged above the center of the bolt and is communicated with a small round hole at the position corresponding to the jacket, an intake port is arranged below the valve body, is covered by the steel ball and jacks the spring above. When the air pressure at the intake port reaches a rated value, the steel ball is jacked and the gas inside the jacket is exhausted out of the cooker through the exhaust hole. The one-way valve according to the invention can ensure the safety of the jacket and no excessive pressure, has heat insulating and preserving efficiency, simple structure and convenient use, and is suitable for the jacket-mounted pressure cooker.

Description

Technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve on a pressure cooker. technical background [0002] One-way valve is an important category of valves, used to control fluid flow in a certain direction. There are many types of one-way valves, most of which use compressed air as the medium. Application number 200520043396.4, titled "A kind of unloading check valve for air compressor" (Announcement No. CN 2802122Y, application date 2005-07-13), is such a one-way valve. The one-way valve disclosed by it includes a valve body and an air inlet pipe joint, an air inlet cavity and a working cavity. The air inlet cavity is communicated with the air inlet pipe joint. There are gaskets and seals on the upper part, an unloading port, and a valve core in the working cavity. And the seal, there is a connecting rod, the ring surface is provided with a vertical ventilation groove and an air inlet groove, and the connecting rod is provided with a...
