Abstract
The utility model provides a membrane type air pressure tank, belongs to the technical field of water feeding systems, and aims to solve the problems that the heated surface of the existing rubber membrane is easily stuck to the wall of a shell, and the service life of the existing rubber membrane is short in service life. The membrane type air pressure tank comprises the shell and the rubber membrane which is fixedly arranged in the shell and is used for dividing the shell into a water storage cavity and an air storage cavity, wherein the air storage cavity is positioned above the water storage cavity; a water inlet communicated with the water storage cavity and an air inlet communicated with the air storage cavity are formed in the shell; the rubber membrane is bowl-type; an opening of the rubber membrane faces the air storage cavity; and a protruded part pressed against the wall of the water storage cavity is arranged on the outer wall of the rubber membrane. By the protruded part, the outer wall of the rubber membrane can be prevented from being in contact with the wall of the shell, and the rubber membrane can be prevented from being stuck to the wall of the shell because of thermal viscosity; and the service life of the rubber membrane is prolonged.
Description
Technical field
The utility model belongs to the water supply system technical field, particularly a kind of air pressure tank.
Background technology
Air pressure tank generally is connected in water system, mainly plays an accumulator.The air pressure tank of air pressure tank original adoption steam-water mixing, and then be improved to the diaphragm-type air-compressed tank that water, vapour separate.As the utility model patent [ZL200720105706.X] in China's application discloses a kind of " air pressure tank ", this air pressure tank comprises housing, be provided with a water inlet in the bottom of housing, one rubber diaphragm is arranged in housing, this rubber diaphragm is by enclosure interior space atmosphere storage-type and air storage chamber, at air storage chamber, one air inlet is arranged, air storage chamber is positioned at the top of reservoir chamber.This air pressure tank does not contact air water by barrier film, so just can guarantee that water quality is not subject to the pollution of gas, has also eliminated because the G&W reaction generates the material to tank corrosion, extends the application life of tank body simultaneously.But the barrier film of this air pressure tank is to be made by rubber, and rubber has thermal viscosity.Be positioned at the diaphragm of rubber surface of storage-type due to the frequent annular in hot water, this surperficial viscosity increases, and this surface is easy to be bonded on housing wall in actual applications, so just makes barrier film unbalance stress everywhere, the application life of having reduced barrier film.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of diaphragm-type air-compressed tank, and this air pressure tank can avoid diaphragm of rubber to be bonded on housing wall, extends the application life of diaphragm of rubber.
The purpose of this utility model can realize by following technical proposal: a kind of diaphragm-type air-compressed tank, it comprises housing and is installed in the diaphragm of rubber that in housing, housing is divided into to water storage cavity and air storing cavity, described air storing cavity is positioned at the top of water storage cavity, offer the water inlet communicated with water storage cavity and the air inlet port communicated with air storing cavity on housing, it is characterized in that, described diaphragm of rubber is a bowl type, the opening of described diaphragm of rubber, towards air storing cavity, has the jut that can be resisted against on the water storage cavity wall on the outer wall of described diaphragm of rubber.
Diaphragm of rubber is divided into air storage chamber and reservoir chamber by the space in housing, but has so just avoided contacting of the interior gas of body and water; Jut avoids the outer wall of diaphragm of rubber to contact with housing wall, has avoided diaphragm of rubber because thermal viscosity is bonded on housing wall, has extended the application life of diaphragm of rubber.
In above-mentioned diaphragm-type air-compressed tank, described jut comprises the bar shaped raised line that is positioned at the transversely arranged protruding grain of some rows on lateral wall and the some longitudinal arrangements on exterior bottom wall.Though salient point has certain viscosity under hot water environment, but salient point is that point contacts with housing sidewall, the lateral wall of barrier film and the contact area between housing wall have been reduced, reduced the power that is subject to housing due to the viscosity of barrier film, in like manner, bar shaped raised line on exterior bottom wall has also reduced the contact area between barrier film exterior bottom wall and housing wall, and the raised line of bar shaped simultaneously can also be strengthened the intensity of diaphragm of rubber bottom, has extended the application life of diaphragm of rubber.
In above-mentioned diaphragm-type air-compressed tank, described protruding grain is over against water inlet.Transversely arranged protruding grain can reduce by the come in pressure of water of water inlet.
In above-mentioned diaphragm-type air-compressed tank, described jut comprises the ring rib be positioned on exterior bottom wall.Ring rib can reduce the contact area between diaphragm of rubber exterior bottom wall and housing wall.
Compared with prior art, a kind of diaphragm-type air-compressed tank of the utility model comprises housing and is installed in the diaphragm of rubber that in housing, housing is divided into to water storage cavity and air storing cavity, air storing cavity is positioned at the top of water storage cavity, offer the water inlet communicated with water storage cavity and the air inlet port communicated with air storing cavity on housing, diaphragm of rubber is a bowl type, the opening of diaphragm of rubber, towards air storing cavity, has the jut that can be resisted against on the water storage cavity wall on the outer wall of diaphragm of rubber.Jut avoids the outer wall of diaphragm of rubber to contact with housing wall, has avoided diaphragm of rubber because thermal viscosity is bonded on housing wall, has extended the application life of diaphragm of rubber.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of diaphragm of rubber in Fig. 1.
In figure, 1, housing; 2, diaphragm of rubber; 21, protruding grain; 22, bar shaped raised line; 3, water inlet; 4, air inlet port.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment mono-
Refer to Fig. 1 and Fig. 2, a kind of diaphragm-type air-compressed tank of the utility model comprises housing 1 and diaphragm of rubber 2.Diaphragm of rubber 2 is fixedly installed on housing 1 and exists, and the space in housing 1 is divided into to water storage cavity and air storing cavity.Air storing cavity is positioned at the top of water storage cavity.Offer the water inlet 3 communicated with water storage cavity in the bottom of housing 1, offer the air inlet port 4 communicated with air storing cavity on the top of housing 1.Diaphragm of rubber 2 is a bowl type, and the opening of described diaphragm of rubber 2 is towards air storing cavity.There is the jut that can be resisted against on the water storage cavity wall on the outer wall of diaphragm of rubber 2.Jut comprises the bar shaped raised line 22 that is positioned at the transversely arranged protruding grain 21 of some rows on lateral wall and the some longitudinal arrangements on exterior bottom wall.Though salient point has certain viscosity under hot water environment, but salient point is that point contacts with housing 1 sidewall, the lateral wall of barrier film and the contact area between housing 1 wall have been reduced, reduced the power that is subject to housing 1 due to the viscosity of barrier film, in like manner, bar shaped raised line 22 on exterior bottom wall has also reduced the contact area between barrier film exterior bottom wall and housing 1 wall, and the raised line of bar shaped simultaneously 22 can also be strengthened the intensity of diaphragm of rubber 2 bottoms, has extended the application life of diaphragm of rubber 2.Protruding grain 21 is over against water inlet 3.Transversely arranged protruding grain 21 can reduce by the come in pressure of water of water inlet 3.
