Abstract
The invention relates to a pressure limiting valve for a heating container, comprising a cylinder barrel with a lower opening, a piston and a pressure spring, wherein the cylinder barrel is provided with pressure relieving holes; the inner wall of the lower opening of the cylinder barrel is provided with a clamping groove which is internally provided with an elastic clamping ring with a notch; the piston is arranged in the cylinder barrel and sealed by liquid and gas; the pressure spring is arranged between the top of the piston and the top plate of the cylinder barrel; and the lower opening of the cylinder barrel is communicated with the inner cavity of the heating container. As the structure is adopted, when steam pressure in the heating container increases gradually, the piston moves upwards, and the pressure spring is compressed; when the steam pressure reaches set pressure, the pressure relieving holes on the cylinder barrel communicate the inner cavity of the heating container and the outside for relieving pressure, therefore, the use is convenient; and the pressure relieving holes are communicated with the inner cavity of the heating container only during relieving pressure, therefore, the blocking of the pressure relieving holes can be prevented.
Description
Technical field
The present invention relates to a kind of pressure limiting valve, especially a kind of pressure limiting valve that is used for heating container.
Background technology
Present prior art, Chinese patent ZL03247947.6, utility model patent title: the improvement of limiting valve of pressure cooker structure.Existing problems are: complex structure, easily take place to stop up relief hole, and quick-fried pot phenomenon takes place, need the running check relief hole, guarantee safety; Use inconvenient.
Summary of the invention
The objective of the invention is: the pressure limiting valve that provides a kind of heating container to use, it can prevent effectively that relief hole from stopping up, and is easy to use.
The present invention is achieved in that the pressure limiting valve that a kind of heating container is used, and its special character is: it comprises cylinder barrel, piston and the compression spring with under shed;
On the described cylinder barrel relief hole is arranged, a draw-in groove is arranged on the inwall of the lower opening of cylinder barrel, be provided with notched snap ring in the draw-in groove, the snap ring support piston; Piston is arranged in the cylinder barrel and the liquid hermetic seal, and compression spring is arranged between the top board of the top of piston and cylinder barrel;
The under shed of cylinder barrel is communicated with the inner chamber of heating container.
The pressure limiting valve that described a kind of heating container is used, its special character is: externally threaded interface is with in the bottom of the flange on the under shed of described cylinder barrel, also comprises a clamp nut, and clamp nut is connected with the external screw thread of interface.
The pressure limiting valve that described a kind of heating container is used, its special character is: described piston has the cavity of an axial under shed, and a blind hole is arranged at the top of piston, and blind hole is as spring pedestal; The lower end of compression spring embeds in the blind hole.
The pressure limiting valve that described a kind of heating container is used, its special character is: blind hole in is arranged on the inner surface of the top board of cylinder barrel, and the upper end of compression spring embeds in the interior blind hole.
The pressure limiting valve that a kind of heating container of the present invention is used, owing to adopt such structure, the steam pressure in heating container rises gradually, piston moves up, compression spring by compression, when reaching setting pressure, remittance on the cylinder barrel presses the hole that the heating container inner chamber is in communication with the outside pressure release, and is easy to use; Relief hole only when pressure release, is communicated with the heating container inner chamber, can prevent that relief hole from stopping up.
