Abstract
The utility model belongs to an improved pressure limiting valve used in a pressure cooker. Exhausting holes of the pressure limiting valve are very short and can be permeated by a steeple head of a valve element, therefore the exhausting holes are difficult to be jammed by food, and explosion of the pressure cooker can be effectively avoided. The utility model has the advantages that the structure is simple and reasonable; dismantling and washing of the utility model are convenient; the utility model can be widely applied to pressure pots in different sizes and standards.
Description
The utility model relates to a kind of improved limiting valve of pressure cooker.
The pressure limiting valve of existing pressure cooker, its spool drops on the exhaust pipe mouth of an elongated hole, and the interior steam of pot overcomes the gravity of pressure limiting valve by the elongated hole on the blast pipe during work, backs down spool, and row is to atmosphere.Because the steam vent on the blast pipe is not only thin but also long, stopped up by food easily, be the major reason that leads to the pressure cooker explosion accident.
The utility model is intended to overcome the existing existing shortcoming of limiting valve of pressure cooker, provides a kind of simple and reasonable, and disassembly, cleaning are convenient, can effectively prevent the limiting valve of pressure cooker that steam vent stops up.
The utility model is achieved in that making a kind of two ends is to be the valve body of ring flange in the middle of the external screw thread, and its endoporus has a plurality of steps.In the endoporus step at valve body top, be separately installed with jump ring and back-up ring.The hole of back-up ring is quincunx, and its periphery is riveted by the material at valve body top.Jump ring is Long Circle, can be in translation under the back-up ring.On the step surface of valve body bottom, a smooth aperture is arranged, be the steam vent that cooperates for spool.In the groove between valve body upper external screw thread section and ring flange, sealing ring is installed.The inner hole sleeve of claw is fixed with nut on the valve body lower end external thread section.Valve body upper external screw thread section is upward through its through hole from the pot cover reverse side, cooperates with internal thread hole on the guide holder and tightens, and tightens the nut that is applied simultaneously, and at this moment, sealing ring is close to the aperture of pot cover inwall, guarantees the sealing between valve body and the pot cover.The external screw thread at spool top is tightened in the screw of hammer bottom, the stepped hole of the cylindrical alignment guide seat of hammer, spool is passed the hole of back-up ring and jump ring, hammer just enters guide holder, the nose cone of spool just in time drops in the steam vent of valve body, when the ejection of strong steam or pot cover were toppled over, because spool blocked by jump ring, thereby hammer can not come off.Anti-stop cover with a plurality of elongated hole is inserted on the claw, the bottom of valve body can be shrouded.The breach that two symmetries are arranged on the guide holder has many groove grooves on the cylindrical of hammer, be beneficial to the insertion and the taking-up of hammer.Firmly hold hammer, spool is just extracted from jump ring; Equally, Anti-stop cover also can be pulled up from claw, is beneficial to the cleaning of part.
Because the steam vent on its valve body of pressure limiting valve of the present utility model is short especially, and the nose cone of spool can see through this steam vent again, so this steam vent is difficult to be stopped up by food, prevents the generation of pressure cooker explosion accident effectively.
Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the vertical view of jump ring among Fig. 1, and Fig. 4 is the vertical view of Fig. 1 guide ring, and Fig. 5 is the upward view of claw among Fig. 1.
Shown in Fig. 1-5, the endoporus top of valve body (10) is separately installed with jump ring (6) and back-up ring (3).The hole of back-up ring (3) is quincunx, and its periphery is riveted by the material at valve body (10) top.Jump ring (6) is Long Circle, can be in back-up ring (10) translation down.On the step surface of valve body (10) bottom, individual exhaust hole is arranged.In the groove between valve body (10) upper external screw thread section and ring flange, sealing ring (7) is installed.The inner hole sleeve of claw (8) is on the external thread section of valve body (10) lower end, and is fixing with nut (9).Valve body (10) upper external screw thread section, be upward through its through hole from pot cover (5) reverse side, cooperate with internal thread hole on the guide holder (4) and tighten, tighten the nut (9) that is applied simultaneously, sealing ring (7) is close to the aperture of pot cover (5) inwall, guarantees the sealing between valve body (10) and the pot cover (5).The external screw thread at spool (2) top is tightened in the screw of hammer (1) bottom, the stepped hole of the cylindrical alignment guide seat (4) of hammer (1), spool (2) is passed the hole of back-up ring (3) and jump ring (6), hammer (1) just enters guide holder (4), the nose cone of spool (2) drops in the steam vent of valve body (10), spool (2) is upwards blocked by jump ring (6), and hammer (1) can not come off.Anti-stop cover (11) is inserted on the claw (8), the bottom of valve body (10) can be covered.The breach that two symmetries are arranged on the guide holder (4) has two groove grooves on the cylindrical of hammer (1), be beneficial to the insertion and the taking-up of hammer (1).Firmly hold hammer (1), spool (2) can be extracted from jump ring (6), and Anti-stop cover (11) also can be pulled up from claw (8).The utility model can be widely used on the pressure cooker of all size model.
