Abstract
The invention discloses a low temperature combined charging valve which is convenient in the maintenance and low in the cost. The invention comprises a valve seat, two valves arranged inside the valve seat and an internal duct communicated with the ports of the two valves. The internal duct is provided with an interface which is butted with an external duct. A check valve is arranged inside the internal duct. The invention is primarily used in various charging devices.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 used in the present invention is: combined charge-filling valve comprises: valve seat is provided with two valves and the internal pipeline that is communicated with two valve ports 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 invention has the beneficial effects as follows: the present invention 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. 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 of the present invention;
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 invention in detail.
As shown in Figure 2, combined charge-filling valve of the present invention, 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 present invention 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.
