Abstract
The utility model discloses a low temperature combination filling valve which is convenient for maintenance and can save cost. The valve comprises a valve seat, two valves, and an internal pipeline for communicating the two ports are arranged in the valve seat, a connector butted with an external pipeline is arranged on the internal pipeline, and a check valve is arranged in the internal pipeline. The valve is mainly used in various filling devices.
Description
Technical field
The utility model relates to combined charge-filling valve.
Background technique
As everyone knows, from a container toward another container, irritate in the process of liquid, need between two containers, be provided with usually and charge pipeline.At present employed charging all is provided with the combined charge-filling valve that is used to open and close pipeline usually in the pipeline, as shown in Figure 1, its structure comprises: valve seat 1, be provided with two valves 2 and 3 and the internal pipeline 4 that is communicated with the port of two valves 2 and 3 in the valve seat 1, internal pipeline 4 is provided with the interface 5 that docks with external pipe.In order to guarantee that liquid can only flow along a direction, the phenomenon that flows backwards does not appear, also in charging pipeline, be provided with safety check 6 usually.So just make the cost that charges pipeline increase, but also increased difficulty and expense that pipeline is safeguarded.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of and be convenient to safeguard and the combined charge-filling valve of escapable cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: combined charge-filling valve, comprise: valve seat, be provided with the internal pipeline of two valves and two valve ports of connection in the valve seat, internal pipeline is provided with the interface that docks with external pipe, is provided with safety check in described internal pipeline.
The beneficial effects of the utility model are: the utility model has adopted integrated design, safety check is moved in the internal pipeline of valve seat, has reduced fabricating cost; And when pipeline is safeguarded, only need combined charge-filling valve is safeguarded, greatly reduce difficulty and cost that pipeline is safeguarded.
Description of drawings
Fig. 1 is the structural representation of the combined charge-filling valve described in the background technique;
Fig. 2 is the broken section structural representation of the left apparent direction of Fig. 1;
Among Fig. 1, Fig. 2: 1, valve seat, 2, valve, 3, valve, 4, internal pipeline, 5, interface, 6, safety check.
Fig. 3 is the structural representation of combined charge-filling valve described in the utility model;
Among the figure: 1, valve seat, 2, valve, 3, valve, 4, internal pipeline, 5, interface, 6, safety check, 7, charge joint.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 2, combined charge-filling valve described in the utility model, comprise: valve seat 1, be provided with two valves 2 and 3 and the internal pipeline 4 that is communicated with the port of two valves 2 and 3 in the valve seat 1, internal pipeline 4 is provided with the flange-type interface 5 that docks with external pipe, is provided with safety check 6 in described internal pipeline 4.
During practical application, the interface 5 of combined charge-filling valve is connected with the delivery outlet of liquid container by charging joint 7, and valve 2 and 3 outlet are connected with the inlet of corresponding container.During work, open valve 2 and valve 3, utilize the pressure that charges liquid self that from liquid container, flows out to back down the safety check 6 that is arranged in the internal pipeline 4, cell therefor is charged; In charging process, when the pressure that charges liquid descended, safety check 6 cut out, realizes check function automatically under the effect of spring force, and need not manual- lock valve 2 and 3, thereby has prevented to charge the refluence of liquid effectively.
The utility model moves into safety check 6 in the internal pipeline 4 of valve seat 1, thereby has reduced fabricating cost by adopting integrated design; And when pipeline is safeguarded, only need combined charge-filling valve is safeguarded, greatly reduce difficulty and cost that pipeline is safeguarded.
