Abstract
The utility model relates to a household sewage gas pressure meter comprising an upper cover, a lower cover, a pointer scale of straight-line display. A window of long groove shape is longitudinally arranged on the wall of the upper cover, and a nozzle is provided below the lower cover. A rolling film is arranged in the lower cover, and the edges of the rolling film are held between the upper and lower covers. A cupulate tray is provided on the upper part of the rolling film, and the bottom of the tray is of disk shape, a horizontal rolling edge is used on the top of the tray, meanwhile, a spring is provided between the bottom of the tray and the top of the inner side of the upper cover. Because the rolling film is made from rubber film of sulfureted hydrogen resistance and the part meeting the sewage gas is made from high-strength ABS plastic of H2S resistance, furthermore, the metal spring is arranged on the upper cavity of the rubber film, the problem of antisepsis is thoroughly solved, consequently, the utility model is of simple structure, high sensitivity, economy, durability, pointer scale of straight-line display and convenient use.
Description
Technical field
The utility model relates to a kind of rural area household biogas pressure tester, is specifically related to a kind of household biogas tensimeter.
Background technology
Rural area household biogas pressure tester in the market mainly contains U type water manometer and capsule pressure gauge.Glass tube on the U type pipe pressure meter is longer, generally all surpasses 1 meter, and the damage easily in making, transport and using of U type table, and can not install in the combined type modulator.Capsule pressure gauge is suitable for for measuring noncorrosive gases, but because of containing a large amount of hydrogen sulfide gas in the biogas, it has stronger corrosive attack to metal, cause be restricted the serviceable life of at present commercially available capsule pressure gauge, its measuring accuracy also constantly descends with the lengthening of service time.In view of above situation, the demand that to develop durable, corrosion resistant novel pressure tester be the biogas component market.
The utility model content
The purpose of this utility model is exactly the deficiency that overcomes existing commercially available biogas pressure tester, manufactures and designs a kind of convenience, durable, cheap biogas pressure tester.
The technical solution adopted in the utility model is: the household biogas tensimeter comprises upper shell, lower house, pointer and graduated scale, below lower house, be provided with to connect and chew, in described lower house, be provided with a rolling diaphragm, the edge clamping of described rolling diaphragm is held between described upper shell and the lower house, described rolling diaphragm top is provided with cup-shaped pallet, this tray bottom is disc, and top is provided with the flange edge of level, is provided with spring between the top in described tray bottom and the upper shell.
Described rolling diaphragm is the cup-shaped rolling film.
Described graduated scale is a straight line pointer displayed scale.
Be provided with the long trough window on the shell wall of described upper shell vertically, this long trough window is positioned at graduated scale central authorities.
The part that described flange edge exposes from described long trough window is as pointer.
The beneficial effects of the utility model are: because the utility model household biogas tensimeter rolling diaphragm is made with the rubber film of hydrogen sulfide corrosion-resistant, design at the low characteristics of biogas pressure, and simple in structure, highly sensitive; The part of contact biogas is all with anti-anti-H
2The ABS highstrenghtpiston of S gas attack is processed into, and metal spring is arranged on the epicoele of diaphragm of rubber, has thoroughly solved anticorrosion problem, and is economical, durable, cost is low; Be provided with straight line pointer displayed scale, intuitive display, easy to use.
Description of drawings
Below in conjunction with accompanying drawing, the utility model content is described further.
Fig. 1 is the utility model schematic appearance;
Fig. 2 is the utility model inner structure synoptic diagram.
Embodiment:
As depicted in figs. 1 and 2, the household biogas tensimeter comprises upper shell 1, lower house 5, graduated scale 8 and pointer 9, is provided with to connect below lower house 5 and chews 6.In described lower house 5, be provided with a rolling diaphragm 4, described rolling diaphragm 4 is a cup-shaped rolling epithelium, its upper edge is clamped between described upper shell 1 and the lower house 5, described rolling diaphragm 4 tops are provided with cup-shaped pallet 3, these pallet 3 bottoms are disc, rim of a cup partly is provided with the flange edge 7 of level, is provided with spring 2 between the top in described pallet 3 bottoms and the upper shell 1; Described graduated scale 8 is a straight line pointer displayed scale, on the shell wall of described upper shell 1, be provided with long trough window 10 vertically, this long trough window 10 is positioned at graduated scale 8 central authorities, and described flange edge 7 just can be used as pointer 9 from the part that described long trough window 10 exposes.
When biogas from connect chew 6 enter the biogas chamber of rolling diaphragm 4 belows in the lower house 5 after, rolling diaphragm 4 scrolls up under the promotion of biogas pressure, promote elastic force upwards motion in the air chamber on rolling diaphragm 4 tops that pallet 3 overcomes spring 2, at this moment the part that described flange edge 7 exposes from described long trough window 10 can intuitively show the size of biogas pressure as pointer 9 by graduated scale 8.
Claims (5)
1. household biogas tensimeter, comprise upper shell, lower house, pointer and graduated scale, below lower house, be provided with to connect and chew, it is characterized in that in described lower house, being provided with a rolling diaphragm, the edge clamping of described rolling diaphragm is held between described upper shell and the lower house, and described rolling diaphragm top is provided with cup-shaped pallet, and this tray bottom is disc, rim of a cup partly is provided with the flange edge of level, is provided with spring between the top in described tray bottom and the upper shell.
2. household biogas tensimeter according to claim 1 is characterized in that described rolling diaphragm is the cup-shaped rolling film.
