Description

The non-return valve device

The utility model relates to by in the outlet that is arranged at the ball valve that the flow direction that makes stream on the connecting pipe of pipe arrangement opens and close the ball-type one-way valve being installed integratedly, thereby not only can seek miniaturization, and can seek the non-return valve that the part price reduces through improvement.

At present, along with era development and living environment complexity, human clothing ,food and housing also will be considered protection of nature, and pursues diversity.In this variation, develop many-sidedly that daily necessities and equipment etc. just can be built peaceful and comfortable life easily.

But, at needs the place of workshop and industrial equipment and living environment equipment is set, industrial water and the fluid as oil etc. will be provided sleekly to the place of needs.At this moment, the fluid that needs is to provide by the pipe arrangement as pipeline, utilizes set threshold switch stream according to the place, opens stream at every turn or close closed channel when needing.

Usually, valve is the device that is adjusted in the discrepancy of gas mobile in the pipeline or liquid, has developed various valves according to purpose and the purposes used, thereby can easily its part as equipment be used.

In multiple valve, ball valve is built-in with the ball member that connects to a direction, rotates the ball member of inserting in the outside, the stream of the pipeline about just switch is attached at easily.

, when the needed long pipe arrangement of the equipment that is provided with, will the ball valve of switch stream and other valve etc. be set respectively according to purpose is set, and one-way valve will be installed, can prevent that so no fluid from flowing backwards.

As mentioned above, when ball valve and other valve and one-way valve are set, just various parts need be set, when according to circumstances making ball valve and one-way valve integrated on pipe arrangement, owing to need its incorporate other method thereby its volume can be increased, it is uneconomic by other method part being set.

The utility model is exactly that ball valve and one-way valve are integrated to be proposed in order to make in view of the above problems, its objective is provides a kind of and different in the past, not only reduce the price of part but also can also seek the non-return valve of miniaturization, because this valve makes the ball-type one-way valve integrated at the outlet side of ball valve, thereby can carry out the switch of stream simultaneously simply at a place and prevent adverse current.

Non-return valve of the present utility model to achieve these goals, it is characterized in that: be arranged to ball valve 1 and ball-type one-way valve 2 one-piece type, promptly form ball valve 1 its ball 6 of a direction stream at central corridor 6 ', with screw rod 4 stationary bushings 5 and liner plate 8 up and down, utilize the above-mentioned stream 7 of handle 3 switches, one-way valve 2 is fixed in the outlet side of this ball valve by key 13, ball 9, spring 11 is set and is pressed into part 10 in proper order in than the big stream 7 ' of stream 7 bores that prolong, thereby prevent fluid countercurrent current.

Fig. 1 is an exploded perspective view of showing the non-return valve device that relates to embodiment of the present utility model.

Fig. 2 is an action sectional view of showing the on off state of non-return valve device of the present utility model.

Fig. 3 is the phase diagram that prevents fluid countercurrent current with non-return valve of the present utility model.

Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.

Fig. 1 is an exploded perspective view of showing the non-return valve device that relates to embodiment of the present utility model.Non-return valve device of the present utility model is owing to make ball-type one-way valve 2 integrated at the outlet side of ball valve 1, thereby can make the valve that plays ball valve and one-way valve effect that in the past separated like that, carries out the switch of stream at a place easily simultaneously and prevents fluid countercurrent current.

That is, on the stream road 7 of above-mentioned ball valve 1, in the Place 6, at the integrated installation ball-type of outlet side one-way valve 2, above-mentioned ball valve 1 utilizes key 13 axial restraints to be connected with one-way valve 2 in central authorities form path 6 '.

Above-mentioned ball valve 1 forms stream 7 in one direction, the path 6 ' that connects in mediad one direction is provided with ball 6, utilizes with screw rods 4 fixing a plurality of linings 5 and the above-mentioned stream 7 of handle 3 switches of liner plate 8 up and down at this ball 6 of part of the vertical position of above-mentioned stream 7 upper shed.

At the outlet side of the ball valve 1 that constitutes like this ball valve 2 that fluid only flows to the stream 7 ' of a direction is set, above-mentioned ball-type one-way valve 2 is fixedly connected on the outlet side of above-mentioned ball valve 1 by key 13, ball 9, spring 11 is set and is pressed into part 10 in proper order in than the big stream 7 ' of stream 7 bores that prolong.

Thereby the utility model is one-piece type as carrying out the switch of stream fluid easily simultaneously in a place and preventing to make the fluid countercurrent current ball valve 1 and ball-type one-way valve 2 to constitute, thereby can expect to reduce cost and miniaturization.

Fig. 2 is an action sectional view of showing the on off state of non-return valve device of the present utility model, pipeline 14 is connected to the inlet screw thread 12 of ball valve 1 and the outlet screw thread 12 ' of ball-type one-way valve 2 by non-return valve device of the present utility model, Fig. 2 (A) is the state that non-return valve device of the present utility model is opened, the handle 3 of ball valve 1 rotates to the left, because the path 6 ' of built-in ball 6 connects in line with stream 7,7 ', thereby flows in fluid pushes ball-type one-way valve 2 by above-mentioned ball valve 1 limit on direct of travel ball 9 limits.

Thereby, non-return valve device of the present utility model, be by mobile by the stream 7,7 ' of incorporate ball valve 1 and ball-type one-way valve 2 to a direction at a place, at this moment, fluid is after by path 6 ' and outlet as the inlet of the stream 7 of ball valve 1, built-in ball 6, extruding is passed through spring 11 and is pressed into and pass through outlet between the part 10 sleekly as the inlet ball 9 of the stream 7 ' of ball-type one-way valve 2.

On the other hand, when by as described above by the stream 7 of incorporate ball valve 1 and ball-type one-way valve 2,7 ' during to fluid countercurrent current that a direction flows, as shown in Figure 3, by being pressed into part 10, spring 11 and ball 9 and just can blocking adverse current simply in the above-mentioned ball-type one-way valve 2.That is,, then be pressed into part 10 and be subjected to oil pressure, by pressure ball 9 stream 7,7 ' is opened circuit, just can prevent the adverse current of fluid by spring 11 if fluid flows backwards to the stream 7 ' as the outlet of ball-type one-way valve 2.

Fig. 2 (B) is a non-return valve device closing state of the present utility model, and the handle 3 of ball valve 1 forwards rotates, and the path 6 ' of built-in ball 6 cuts off stream 7,7 ', prevents that fluid from flowing to the stream 7 ' of ball-type one-way valve 2.That is, the path 6 ' of the ball 6 in the ball valve 1 and stream 7,7 ' be not in a straight line direction, and above-mentioned path 6 ' seals on wall, owing to cut off streams 7,7 ' with ball 6, therefore reaches the purpose of regulation.

Thereby, non-return valve device of the present utility model makes the valve body of separation small-sized ground integrated, not only can use the stream 7 of the handle 3 switches one direction fluid of ball valve 1 at a place, 7 ', and can use the adverse current that stops fluid with ball valve 1 incorporate ball-type one-way valve 2 simply.

As mentioned above, if employing the utility model, owing to make ball valve and one-way valve integrated, not only with in the past product is different, the part price is descended, and owing to can expect that miniaturization makes the ball-type one-way valve integrated in the outlet port of ball valve like that, thereby a kind of non-return valve device that carries out the switch of fluid flowing path at a place easily simultaneously and prevent fluid countercurrent current can be provided.
