Abstract
The utility model relates to a muffling pressure-limiting valve, which is a muffling pressure-limiting device used on a pressure cooker. The muffling pressure-limiting valve is designed according to the principle of a small hole spray muffler and an expansion chamber muffler. The muffling pressure-limiting valve is a combined muffling pressure-limiting valve, composed of a spray type muffler, an expansion chamber muffling valve body, a valve core, an end cover and a drop handle into an integration. The muffling pressure-limiting valve is arranged on a valve seat on the cover of the pressure cooker in use. The muffling pressure-limiting valve has the advantages that the function of an original limiting valve is kept, noise is decreased, horror mentality can not be generated by people because of over big noise in use, air exhaust is safe, etc.
Description
The noise elimination pressure-limit valve is to use a kind of noise elimination pressure limiting device on pressure cooker.
Used limiting valve of pressure cooker is a kind of a kind of better simply pressure-limit valve according to the pressure cooker pressure design at present.When pressure cooker reached the authorized pressure exhaust, without any silencer, the noise that sends was very big, and the howling that sends allows people Wen Ersheng fear, even made the people dare not the working pressure pot.
The purpose of this utility model designs exactly and a kind ofly can play safety effect, and the big shortcoming of noise in the time of overcoming exhaust again has the pressure cooker noise elimination pressure-limit valve of silencing apparatus on pressure-limit valve.
The noise that limiting valve of pressure cooker sends belongs to the exhaust jet noise, and the effective ways of controlling this noise are to install at relief opening to have diffusion, reduction of speed, frequency conversion and change spray flow parameter.The utility model is a kind of combined type noise elimination pressure-limit valve according to the principle design of micropore jet silencing apparatus and reactive muffler (expansion chamber silencing apparatus).
Now utilize the example in the accompanying drawing, the noise elimination pressure-limit valve is described in detail.
Accompanying drawing 1 is the assembling assumption diagram of pressure cooker noise elimination pressure-limit valve.
Accompanying drawing 2 is structural drawing of expansion chamber noise reduction valve body.
The noise elimination pressure-limit valve is made up of spray formula silencing apparatus (2), expansion chamber noise reduction valve body (3), spool (4), end cap (5) and drop handle (6).Valve seat (1) is installed on the pressure cooker cover.During use the noise elimination pressure-limit valve is contained on the valve seat (1), as shown in Figure 1.When pressure cooker pressure surpassed authorized pressure, gas reached the purpose of pressure limiting just from the center hole jack-up noise elimination pressure-limit valve steam discharge of valve seat (1).Spray formula silencing apparatus (2) is inverted round barrel shape, and two-layer exhaust port is arranged at the bottom, is 30 degree angles and is evenly distributed on the circumference of spray formula silencing apparatus (2).Expansion chamber noise reduction valve body (3) has two-layer circumferential flange as shown in Figure 2, is evenly distributed with four exhaust holes at the upper edge of first layer flange circumference 90 degree.During exhaust, gas jack-up spool (4) enters steam chest A, enter steam chest B by four apertures on expansion chamber noise reduction valve body (3) circumference, and then entering steam chest C by formed gap between first layer circumferential flange on the expansion chamber noise reduction valve body (3) and the spray formula silencing apparatus (2), discharge in the two-layer aperture of last gas from spray formula (2) circumference, second layer circumferential flange and the formed gap of spray formula silencing apparatus (2) on the expansion chamber noise reduction valve body.By triple diffusion, reduction of speed, frequency conversion, thereby reached the purpose of eliminating the noise.
The advantages such as the utility model has kept the effect of former pressure limiting valve, and has the noise of reducing, and does not cross ambassador people because of noise during use and produces the feared state of mind, and exhaust, safety is reliable.
Claims (3)
1, the noise elimination pressure-limit valve of using on a kind of pressure cooker, it is characterized in that it forms one by spray formula silencing apparatus (2), expansion chamber noise reduction valve body (3), spool (4), end cap (5) and drop handle (6), be contained on the valve seat (1) on the pressure cooker cover, make the noise elimination pressure-limit valve form steam chest A, steam chest B and steam chest C.
2, noise elimination pressure-limit valve according to claim 1 is characterized in that spray formula silencing apparatus (2) is inverted round barrel shape, and two-layer exhaust port is arranged at the bottom, is 30 degree angles and is evenly distributed on the circumference of spray formula silencing apparatus (2).
3, noise elimination pressure-limit valve according to claim 1 is characterized in that on the expansion chamber noise reduction valve body (3) two-layer circumferential flange being arranged, and is evenly distributed with four exhaust holes at the upper edge of first layer flange circumference 90 degree.
