Abstract

The invention discloses a swing check type recoil reversing two-position three-way valve and belongs to the automatic valve technical field. The check type recoil reversing valve mainly applies to the fields of medium recoiling, reversing needed when walking back and the like, and solves problems such as delayed movement of a product and a mechanism or complex in controlling. The check type recoil reversing valve is characterized in that a valve clack is hinged behind a three-way valve body hinging seat, the valve clack can at least swing in a valve cavity of the three-way valve body and a C-mouth pipe around a hinging point, when the valve clack swings to a random end of the two ends, the valve clack and an inner port of an A-mouth pipe or a B-mouth pipe can contact and form a sealing.

Description

Swing backflush reversing valve

Technical field

The invention belongs to the automatic valve technical field, be specifically related to swing backflush commutation two position three-way valve.

Background technique

The public such as threeway, three-way valve, three-port check damper know, many application such as it normally connects, branch, keying, flow control, flow direction control, but all can not realize reliable recoil commutation etc.; Certainly, during recoil, commutation can be adopted linking mechanism, manual control, check valve set control, the control of rise-fall type recoil valve, the control of electronic (magnetic) valve system etc., though the above commutation that can reliably recoil is usually all moved sluggish or needed many peripheral unit servo.

Summary of the invention

Technical problem to be solved by this invention is: in order to reach the pipeline medium in recoil, the capable time commutation of tracing back, similar products, mechanism action is sluggish or control complicated problem.

In order to address the above problem, the present invention discloses a kind of swing backflush reversing valve, comprises three way valve and flap; Flap comprises hinged structures, two sides seal operation lobe, skirt lobe, and hinged structures and skirt lobe are respectively at the two ends of two sides seal operation lobe; The skirt lobe can divide fixedly skirt lobe and the large class of hinged skirt lobe two by Placement, the skirt lobe can divide rectangular skirt lobe, trapezoidal skirt lobe, circle (transferring spoon splendid attire section shape, ellipse etc.) shape skirt lobe, special-shaped skirt lobe etc. by shape, sets up the purpose of skirt lobe: be in recoil, to trace back when capable be effective, the effect that fast rotary has opened guide, startup of whole flap.

In such scheme, three way valve has three medium channels at least: A mouth pipe, B mouth pipe, C mouth pipe, these three medium channels can be according to techniques, coordinate flap to revolve open etc. be out of shape, reducing.

In such scheme, a hinged seat is arranged in three way valve, the three way valve hinged seat exists: locate around the three way valve that the inner port of A mouth pipe and B mouth pipe or the inner port of radially amplifying intersect or its.

In such scheme, a valve pocket is arranged in three way valve, the valve pocket of three way valve is by the inner port of A mouth pipe, B mouth pipe, C mouth pipe or radially amplify inner port and intersect in twos and form.

In such scheme, after flap was hinged on the three way valve hinged seat, flap can swing in the valve pocket of three way valve and C mouth pipe at least around articulating point, and when flap was rocked to any end at two ends, flap can contact and form sealing with the inner port of A mouth pipe or B mouth pipe.

In such scheme, contact with the inner port of B mouth pipe when flap when coincideing, skirt lobe or part skirt lobe are in C mouth pipe, and the skirt lobe favours relative axis and the radial line of C mouth pipe usually, continue that you start whole flap and revolve and open so that recoil medium motion power can better force in the skirt lobe.

In such scheme, two sides seal operation lobe can have the secondary lobe that is arranged on both sides, lobe center or airtight cavity is set or magnetic material etc. is set, to strengthen the speed that seals, slows down keying; Usually lower three way valve, flap can arrange elastic component, so that flap does not freely swing and keep in touch with an inner port wherein.

The invention has the beneficial effects as follows: commutation rapidly, economy and durability, application be wide.

In accompanying drawing: A mouth 1; A mouth pipe inner port, sealing seat 1a; A mouth pipe inner port, sealing seat 1b; Three way valve hinged seat 2; B mouth 3; B mouth pipe inner port, sealing seat 3a; B mouth pipe inner port, sealing seat 3b; C mouth 5; Three way valve 6; Hinged structures 7; Two sides seal operation lobe 8; Skirt lobe 9; Flap 11; The inner dead line 21 of C mouth pipe; Slow Close chamber 31; Technique, access hole 41.

Embodiment

With reference to each accompanying drawing, shape, arrangement and the field etc. of three medium pipelines of concrete structure, selection, technique, three way valve 6 are free improvement, intersection, Combination application as required.Need etc. for fear of hinging hole, groove or technique, three way valve 6, flap 11 can adopt Split type structure; A mouth 1, B mouth 3, C mouth 5 available screw thread, flange, pipe clamp etc. as required access in pipelines, and when usually accessing, C mouth 5 pipes are tried one's best perpendicular to installing on ground with its relative axis; But material O shape rubber ring, sealing gasket, alloy, pottery and the body valve body etc. of each inner port, sealing seat.

Shown in Figure 1, comprise three way valve 6 and flap 11; Three way valve 6 has at least: can with hinged structures 7 mutually coincide the three way valve hinged seat 2 that forms linkage, A mouth 1 tube chamber, B mouth 3 tube chambers, C mouth 5 tube chambers and at four cavitys of valve pocket of the shape triangular in shape of central position; The sealing surface of two sides seal operation lobe 8 all has in the narrow U-groove bevel of opening and groove and is embedded with O-ring seals, and this design not only can guarantee seal request but also simple in structure, and flap 11 revolves Qi Shineng and plays certain buffer function simultaneously; flap 11 can repeat in the two ends of C mouth 5 tube chambers and valve pocket (being also two stops of shown position) around articulating point after being hinged on three way valve hinged seat 2, following the arc mark swings, when usually using, flap 11 is because of from gravity, medium makes it be adjacent to inner port (3a at B mouth 3 pipes from the motoricity of A mouth 1 to

C mouth

5,3b) also form sealing, work as recoil, tracing back, medium enters from C mouth 5 when capable, continue your medium motion is tried hard to recommend moving skirt lobe 9 and is restarted whole flap 11 and revolve and open, thereby make flap 11 be adjacent to inner port (1a at A mouth 1 pipe, 1b) also form sealing, commutate simultaneously to B mouth 3.

In like manner design: in Fig. 3, flap 11 is Olive Shape Slow Close lobe, Slow Close chamber 31 is arranged in lobe, flap 11 utilizes its arc sealing surface to be nested in and forms sealing on relative inner port tube wall, its skirt lobe 9 is for transferring spoon splendid attire section shape, when the design of this skirt lobe is " trace ", MEDIA FLOW is less through the cambered surface flow resistance, and medium flows into the more favourable flap 11 of arc cover and revolves and open when " flyback "; Fig. 4 is the example of hinged skirt lobe, and it is in order to adapt to easy to connect with female equipment that its C mouth 5 pipe external port are designed to tilt with respect to other external port; Fig. 5 has increased technique, access hole 41, and adopts just staggered double seal form of Internal and external cycle, and its skirt lobe 9 adopts flexible material can effectively dwindle overall volume; Fig. 6 adopts positive Three way type, may there is no obvious separatrix between its each inner port and valve pocket, and the nested double-cone type elastic packing cone of its flap 11 utilizes the conical surface to be nested in and forms sealing on relative inner port tube wall.

Certainly, in like manner design of the present invention is also a lot, certainly, the above and accompanying drawing just for convenience of description with explain spirit of the present invention.
