Description

[Detailed Description of the Invention] The present invention relates to a weight body for a pressure regulating device used in a pressure cooker or the like.

Conventionally, the weight of the weight of this type of pressure regulator is determined by the steam pressure and the size of the steam outlet. Conventional weight bodies are made of metals such as stainless steel and are mainly machined, so cutting errors when manufacturing a large number of units tend to cause variations in weight, which not only leads to variations in set pressure but also poor workability. It had the disadvantage of being expensive.

The present invention has been made to eliminate the above-mentioned drawbacks, and includes forming a wax-shaped recess at the open end of the lower surface of the weight body having a valve body made of synthetic resin, and a step lowered by one step on the plane of the recess. By inserting the spring body that sandwiches the steam exhaust pipe into the stepped portion, and by fitting and fixing the suppressor into the recess located outside the stepped portion, the weight bodies have little individual variation and can be made uniform. It is an object of the present invention to provide a weight body for a pressure regulator that is inexpensive to hold and requires no processing.

An embodiment of the present invention will be described below with reference to the drawings.

The structure of the embodiment is as shown in FIGS. 1 to 5. Reference numeral 1 denotes a lid of the pressure regulator, and 2 denotes a steam exhaust pipe, which is erected on the lid 1 and an axis communicating between the inside and outside of the lid 1. It has a steam ejection hole 3 at the top thereof, and a neck part 4 which is continuous with the neck part 11 and has a larger diameter is formed at the upper part. Reference numeral 5 designates a weight body made of synthetic resin, which has a cap shape as shown in FIGS. 3 and 6, and has a valve body 8 in the form of a conical projection at the center of the inner bottom. This weight body 5 is formed by fitting the tip of the conical projection of the valve body 8 into the steam ejection hole 3 of the head 4 formed in the steam exhaust tube 2.
is placed on the steam exhaust pipe 2. Note that there is a wax-like recess 6 at the open end of the lower surface of the weight body 5;
A step portion 7 is provided which is further lowered by one step on the plane. Reference numeral 9 denotes a spring body, which is formed by forming a wire rod or a thin plate material into an elliptical shape and cutting off one end of the elliptical portion. Reference numeral 10 denotes a deterrent body which has a ring shape and is made of a metal material having a relatively high specific gravity.
The spring body 9 that sandwiches the steam exhaust pipe 2 is attached to the stepped portion 7.
At the same time, the suppressor 10 is fitted into the recess 6 located outside the step 7, and the open end of the weight 5 is fixed by thermal deformation. In this way, the weight body 5 is placed over the steam exhaust pipe 2, and the tip of the valve body 8 is fitted into the steam jet hole 3 which is opened in the head 4 formed in the steam exhaust pipe 2, and the weight body 5 is closed. It is to be placed.

The operation of this embodiment will be explained below. In the above structure, steam is discharged by lifting the weight body 5 by the steam pressure from the lid body 1 side, thereby disengaging the steam jet hole 3 from the valve body 8. However, if the steam ejection hole 3 is temporarily blocked and steam is ejected all at once for some reason and the weight body 5 is lifted above a certain level, the short circular part of the spring body 9 will cause the steam exhaust tube 2 to emit steam.
The neck 11 of the head 4 and the neck of the head 4 are sandwiched and locked to prevent dangers such as the weight 5 flying up and a large amount of steam spewing out. This weight body 5 is made of synthetic resin, which eliminates variations in one-piece processing, so that the weight body 5 can always maintain a pressure that is consistent with the set pressure without any variation in weight, and has a simple configuration with a small number of parts. This is the result.

According to the present invention, the weight body is made of synthetic resin, and a recess is integrally formed at the open end of the lower surface, and a step is formed on the plane of the recess, a spring is inserted into the step, and a metal deterrent is fixed to the recess. As the steam exhaust tube is sandwiched between spring bodies and the weight body is restrained, the weight body maintains uniformity with little variation among the individual weight bodies, and has the effect of creating an inexpensive structure that eliminates machining, improving not only safety but also its practicality. is extremely high.

Note that the valve body 8 of the weight body 5 as shown in FIG. 6 may be formed integrally with the weight body 5 instead of being formed separately as in FIG. 1, and the latter further improves moldability and contributes to cost reduction. It is something.
