Abstract
The utility model relates to a household dimethyl ether gas pressure regulator, comprising an upper valve body and a lower valve body combined into a whole via a leather diaphragm; wherein, a spring is arranged in the upper valve body; an inlet channel and an outlet channel are respectively arranged on two sides of the lower valve body. The utility model is characterized in that the leather diaphragm is made of non-metal rubber; a pad is arranged at the top of the inlet channel; a cushion made of ethylene propylene diene rubber is arranged on a valve head. The utility model has the advantages of strong resistance to dimethyl ether gas, avoidance of danger of gas leakage and explosion for long term usage, and safe and reliable use.
Description
Technical field:
The utility model belongs to a kind of regulator, designs a kind of gas pressure regulator, governor of installing in civilian bottled dimethyl ether fuel gas system especially.Be particularly related to the family expenses dimethyl ether fuel gas pressure governor of a kind of energy dimethyl ether resistant corrosion.
Background technique:
Dimethyl ether fuel gas is applied to civilian bottled supply, in China just in the laundering period.Many suppliers and technical paper are all taked the attitude of avoiding to the corrosivity of dimethyl ether, and lpg regulator and burner can be directly used in proposition, and need not any transformation.Though short-term does not have accident to take place, carry out dimethyl ether through us and make to contrast Journal of Sex Research with liquefied petroleum gas (LPG) corrosivity and show that the corrosivity of dimethyl ether and liquefied petroleum gas (LPG) has bigger difference.If the corrosion protection parts that present household liquified controlled atmosphere depressor is commonly used are immersed in volume change in the dimethyl ether, weight rate is bigger, shows that then the ability of anti-pure Dimethyl ether combustion gas is relatively poor.The long-term danger that exists gas leakage and blast of using.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of family expenses dimethyl ether fuel gas pressure governor is provided, and this pressure governor possesses good dimethyl ether resistant corrosivity, and is safe and reliable, can eliminate accident potential effectively.
The technical solution of the utility model is: a kind of family expenses dimethyl ether fuel gas pressure governor, comprise upper valve body and following valve body, and both are laminated with by epithelium and are integral, and spring is housed in the upper valve body, and the both sides of following valve body are respectively gas-entered passageway and outlet passageway; It is characterized in that: epithelium adopts nonmetal rubber to make, and at the top of gas-entered passageway pad is housed, and the rubber cushion made from ethylene propylene diene rubber is housed on valve head.
The utility model has the advantages that: epithelium of the present utility model adopts nonmetal rubber to make, and pad that is equipped with at the top of gas-entered passageway and the rubber cushion made from ethylene propylene diene rubber that on valve head, is equipped with, if be immersed in volume change in the dimethyl ether, weight rate is less, the ability that shows anti-pure Dimethyl ether combustion gas is stronger, therefore long-term use does not exist the danger of gas leakage and blast, and is safe and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure: a kind of family expenses dimethyl ether fuel gas pressure governor, comprise upper valve body 1 and following valve body 2, both are laminated with by epithelium 3 and are integral, and spring 4 is housed in the upper valve body, and the both sides of following valve body are respectively gas-entered passageway 5 and outlet passageway 6.Epithelium adopts nonmetal rubber to make, and at the top of gas-entered passageway pad 7 is housed, and the rubber cushion made from ethylene propylene diene rubber 8 is housed on valve head.
