Because of the adoption of the unique structure that the valve body can not be separated from the exhausting rod, the utility model not only can satisfy the using performance of various pressure-cooker safety valves, but also can ensure the valve body not to be damaged due to falling on ground caused by various reasons, and the utility model can also avoid influencing the use of the pressure cooker for the reason that users can not find the valve body. The utility model is a pressure-cooker safety valve which has the advantages of reasonable structure, convenience, practicability and high safety.
Description
The utility model is a kind of easing valve that is used for pressure cooker, belongs to the renovation technique of the used easing valve of pressure cooker.
The existing used easing valve of pressure cooker, the structure that it adopts valve body and air exhaust rod to be separated mostly, have only in use just body cap on air exhaust rod, valve body was easily washed out born when the shortcoming of its existence was to use by pot inner pressure, this not only causes valve body to damage, be easy to injure by a crashing object the user, safety in utilization is not good enough yet; In addition, because valve body and air exhaust rod are separated, the storing of valve body makes the user greatly worried, and careless slightly valve body just knocks over and lands, so that damages valve body and damage user's trick again; Make the user more irritated be exactly when often being badly in need of using, but how also can not find valve body, can only have to use instead other cooker cooked food.
The purpose of this utility model is to overcome above-mentioned shortcoming and the pressure cooker easing valve that provides a kind of valve body and air exhaust rod to be separated, it both can guarantee the security used, can guarantee again valve body not the reason a variety of causes fall on the ground and make valve body to damage, also can avoid the user to influence the use of pressure cooker because of can not find valve body.
Structural representation of the present utility model as shown in drawings, include valve body (1), air exhaust rod (2), vent plug (3), wherein the middle part of valve body (1) is provided with several steam vents (11), air exhaust rod (2) is for being provided with the hollow rods of through hole (21), vent plug (3) is packed in the top of valve body (1), its position is corresponding with the position of through hole (21), and the bottom of valve body (1) is provided with the corresponding through hole of middle part diameter (12) with air exhaust rod (2), the middle part of air exhaust rod (2) is located on the through hole (12), but its underpart is provided with holding at the location scrobicular ring (22) on the pot cover and air exhaust rod (2) can be fixed on securing member (4) on the pot cover, and its top is provided with can avoid valve body (1) to be washed out born positioning convex ring (23) by pot inner pressure.
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing:
Structural representation of the present utility model as shown in Figure 1, include valve body (1), air exhaust rod (2), vent plug (3), wherein the middle part of valve body (1) is provided with several steam vents (11), air exhaust rod (2) is for being provided with the hollow rods of through hole (21), vent plug (3) is packed in the top of valve body (1), its position is corresponding with the position of through hole (21), and the bottom of valve body (1) is provided with the corresponding through hole of middle part diameter (12) with air exhaust rod (2), the middle part of air exhaust rod (2) is located on the through hole (12), but its underpart is provided with holding at the location scrobicular ring (22) on the pot cover and air exhaust rod (2) can be fixed on securing member (4) on the pot cover, and its top is provided with can avoid valve body (1) to be washed out born positioning convex ring (23) by pot inner pressure.Above-mentioned securing member (4) can be threaded connector, can be provided with several passages (41) on its sidewall, and passage (41) communicates with the through hole (21) that air exhaust rod (2) is provided with.For processing, the convenience of installing and guarantee serviceability, above-mentioned vent plug (3) can include push rod (31) and obturating plug (32), wherein the top of push rod (31) is plugged on the obturating plug (32), the middle part is set on the top of valve body (1), the bottom places the inner chamber of valve body (1), and its position is corresponding with the through hole (21) that air exhaust rod (2) is provided with.Convenience for processing, installation, above-mentioned valve body (1) can include valve body (1A), valve base plate (1B) and valve top cover (1C), and valve body (1A) places on the valve base plate (1B), and is attached thereto, valve top cover (1C) places the end face of valve body (1A), and is attached thereto.Above-mentioned valve base plate (1B) also can be made with valve body (1A) integral body.Better for guaranteeing the sealing in the valve pocket, be respectively equipped with pad (5,6) below the top and valve top cover (1C) of the inner chamber of above-mentioned valve body (1), valve base plate (1B).
When the utility model uses, air exhaust rod (2) bottom is set on the set position, hole of pot cover, make location scrobicular ring (22) holding that air exhaust rod (2) bottom is provided with on pot cover, and the securing member (4) of below pot cover, screwing on, then air exhaust rod (2) can be fixed on the pot cover.When just beginning cooked food, push rod (31) in the vent plug (3) is blocked the through hole (21) that air exhaust rod (2) is provided with, make pot interior gas can not be discharged to outside the pot, when gas pressure in the pot surpasses setting value, the passage (41) that is provided with through securing member (4) sidewall of gas in the pot then, through the through hole (21) that air exhaust rod (2) is provided with the push rod (31) on the vent plug (3) is backed down again, make gas enter the inner chamber of valve body (1), and several steam vents (11) discharge that is provided with from valve body (1) middle part, so that pot inner pressure keeps relative stability.Above-mentioned push rod (31) is backed down by gas in the pot and drives valve body (1) along air exhaust rod (2) up in the motion process, because air exhaust rod (2) is provided with positioning convex ring (23), so can avoid valve body (1) to be washed out born by pot inner pressure.
