Abstract

The utility model relates to a vehicle tank for transporting liquid. The utility model is formed mainly by that an inner lining soft bag (2) is additionally arranged in a vehicle tank, a plurality of air holes (3) with on-off devices are opened at the top of the casing (1) of the vehicle tank, a liquid gateway (11) connected with a controllable reversing valve (10) is arranged at the bottom of the casing (1) of the vehicle tank, and an access door (5) used for swapping the inner lining soft bag (2) is opened at the casing (1) of the vehicle tank. The utility model can prevent the pollution generated by that external air can be introduced during the exchange of air and liquid when the vehicle tank feeds liquid, and can provide vehicle tanks which are convenient for transporting different liquids. The utility model is suitable for transporting various liquids, particularly drinking water.

Description

The gas-liquid insulation recessing of the soft bag of band liner

The utility model relates to the structural development of shipment liquid with recessing,

The recessing that loads and transports liquid now substantially all is the individual layer pot shell, if with after thoroughly do not clean the pot shell inwall, just should not fall to transport inhomogeneity liquid.In addition, in shipment, regular meeting's ingress of air, this is for foodstuff liquid, in case in the liquid that infiltrations such as airborne dust, germ, pernicious gas are loaded and transported, can cause contamination and deterioration.Have, along with the raising of people to the drinking water quality requirement, barreled send water forward canalization quality classification water supply direction to develop again, but this will face the big problem of yard piping laying investment.For this reason, the someone considers with tank car the roof tank of water transport to each building, building, delivers to each family by pipeline within doors then, though this can reduce expending of pipe laying, also has ingress of air and causes secondary pollution problem.

The utility model is intended to address the above problem, and a kind of different liquids of being convenient to allocate and transport is provided, and can effectively avoid the recessing of the gas-liquid contact pollution that brings.

The utility model is achieved in that and a shape and volume is set with the corresponding soft liner bag of recessing outer casing inner wall in hard recessing shell, and the liner bag adopts the material that is suitable for loading and transporting liquid to make.Offer the side door that is used to change the liner bag on the recessing shell, offer the side door place and be arranged in as recessing rear side etc. and be convenient to change liner bag part.For ease of observing actual liquid storage in the liner bag, the liquid level form can also be set on side door.A plurality of breather holes are offered at the top of recessing shell, and opening and closing device is equipped with at the breather hole place, and when the soft bag of liquid turnover, this opening and closing device is opened, otherwise, close breather hole.Recessing bottom is provided with one and one goes out population with controlled change-over valve joins.Controlled change-over valve can be at feed flow, be stranded liquid, get between the liquid level and change.For ease of liquid in the recessing being conducted to the unapproachable area of vehicle, can being provided with one and going out population by fast joint and recessing bottom and refute the shared bridge tube load-transfer device that connects mutually.If want further liquid to be delivered to eminence by load-transfer device, perhaps force feed then can also go out between population and the shared bridge tube load-transfer device liquid pump is set to canned container fast.

If utilize structure of the present utility model, then the recessing shell only plays the support effect, requires and working accuracy thereby can reduce its material, reduces the shell cost significantly.The employing of the soft bag of liner has made things convenient for the shipment of changing class of liquids, changes the liner bag as long as the user need not thoroughly to clean the recessing inwall and gets final product simple realization.And, because this structure is when getting liquid and feed flow, need not the gas-liquid exchange, but under bar pressure and action of gravity, allow the soft bag subside and feed flow, thereby avoided air to introduce the pollution of liquid effectively with the gas-liquid isolation method by opening breather hole.The fast joint place adds dust boot and has further contained pollution.

Fig. 1 is that the master of expression the utility model one embodiment looks the structural representation with right line of vision;

Fig. 2 is the scheme drawing that controlled change-over valve places the annexation of different operating position among presentation graphs 1 embodiment;

Below in conjunction with accompanying drawing, further introduce the utility model for embodiment.

As shown in Figure 1, the recessing of present embodiment adopts profile to be the metal case 1 of oval column substantially, and the right lateral side of this shell 1 has the side door 5 of band liquid level form 6.Shell 1 top is provided with the breather hole 3 of 2-3 charged magnet valve automatic switch device, when liquid turnover recessing, breather hole 3 is opened automatically, transportations etc. are not during liquid in-out, SELF CL breather hole 3, recessing bottom are provided with a gangway 11 that joins with controlled change-over valve 10, when change-over valve 10 is in A, O, B state, the position that be respectively feed flow, is stranded liquid, gets liquid, change-over valve 10 are refuted mutually with shared bridge tube load-transfer device 7 by the fast joint 8 of band dust boot and are connect.This routine recessing is considered to be mainly used in the shipment potable water, so liner bag 2 adopts and recessing shell 1 inner wall shape is similar, size is slightly larger than the soft bag of thin type food stage rubber and plastic of recessing internal volume.For ease of to high building roof tank supply drink water, also between gangway 11 and shared bridge tube load-transfer device 7, the adjustable infusion pump of high low lift 9 is set as shown in Figure 2.Utilize the present embodiment structure, can under the situation of not opening side door 5, conveniently learn the internal memory liquid measure, open side door 6 and can conveniently change the soft bag 2 of liner again, just can lean on air pressure, gravity fluid without the gas-liquid exchange during feed flow, reach the purpose of this utility model fully.As required, also can be in recessing both sides configurations filling liquid chamber 14, utilize infusion pump 9 with the quick force feed of liquid to canned container.
