Description
Technical field
The present invention relates to valve technology field, refer to particularly it is a kind of groove fire-fighting butterfly valve.
Background technique
What at present, the sealing pair of most soft sealing butterfly valves adopted is: rubber ring cooperates with the stainless steel valve seat, rubber lining valve body cooperates with all steel butterfly plate or at the stainless cast iron butterfly plate of sealing surface spraying.Former structure is complicated, and latter's material and processing cost are higher.
In addition, the valve shaft of traditional butterfly valve with the butterfly plate linkage structure is: pin is connected, spline joint and polygonal connect.These linkage structure processing, assembly technology complexity, the self contering poor effect of butterfly plate.
The indicator of opening structure of tradition butterfly valve is: at driver top configuration rotary indicator and dial, this structure can only be in the other size that just can see the shown butterfly valve opening of indicator of opening clearly of driver.
The tradition butterfly valve is under the situation because of mistake moment of torsion some or certain damage parts, and its indicator of opening can not reflect the aperture size of butterfly valve truly.
It is to adopt being rigidly connected of flange and bolt that most of fire valves on water supply network are connected with pipeline, and this Placement produces the problem that stress is concentrated unavoidably.Because pipe vibration causes the load that alternately changes, the distortion of pipeline support face or the variation that colds and heat succeed each other in season etc. and can cause valve and pipe deforming, causes valve or pipeline breaking when serious.In addition, need to be on pipeline when adopting being rigidly connected of flange and bolt welded flange, the corrosion-inhibiting coating during welding on the pipeline is destroyed, therefore, the Anticorrosion Problems of flange connection has also become a difficult problem.
Summary of the invention
Purpose of the present invention is exactly the deficiency that will solve the above-mentioned background technology, and the groove fire-fighting butterfly valve of the Placement of a kind of structural type that changes traditional butterfly valve and itself and pipeline is provided.
Technological scheme of the present invention is: a kind of groove fire-fighting butterfly valve, comprise valve body and live axle, described valve body upper end is provided with the adpting flange that is fixedly connected with it, be provided with the valve seat and the butterfly plate that cooperatively interact in the described valve body, be connected with drive unit on the described live axle, the live axle upper end is passed adpting flange and is rotationally connected with adpting flange, described live axle lower end enters in the valve body and is in transmission connection with butterfly plate, it is characterized in that: described butterfly plate upper end offers attachment hole, the butterfly plate lower end offers circular hole, the lower end of live axle is and the flat square toes of butterfly plate upper end attachment hole Spielpassung, has the gap that can guarantee the two generation relative movement between described flat square toes and the attachment hole; Described valve body lower end is provided with the bottom axle that matches with the circular hole of butterfly plate lower end.
In such scheme:
Described drive unit comprises driver, and described driver is arranged on the adpting flange upper end, and the driver driven shaft passes and is fixedly connected with live axle.
Described live axle is fixedly connected with by flat key with driver.
In such scheme:
Described live axle upper end portion is fixedly connected with indicator board.
Described live axle upper end is provided with opening slot, and indicator board is vertical to be contained in the opening slot, and indicator board is fixedly connected with live axle by screw.
Be provided with the live axle lining between described live axle and the adpting flange, the live axle lining plays the function that prevents the live axle wearing and tearing.
Described bottom axle lower end is connected with valve body screw thread, and insert in the circular hole of butterfly plate lower end bottom axle upper end, is provided with the bottom muff between the circular hole of bottom axle upper end and butterfly plate lower end.
Described valve body is connected with pipeline by clip, and described clip is locked by screw bolt and nut, is equipped with the groove that is complementary with clip on described valve body and the pipeline, and the limit mouth at clip two ends imbeds respectively in valve body groove and the pipeline groove.
The inwall of the groove of the corresponding valve body of described clip and pipeline is provided with groove, is provided with seal ring in groove.
Described butterfly plate is coated with rubber layer; Described valve body inner and outer surface is coated with the molding powder layer.
Working principle of the present invention is:
When rotary driver, driver drives the live axle rotation by flat key, cooperatively interacting of the attachment hole that live axle is offered by the flat square toes in its lower end and butterfly plate upper end drives the butterfly plate rotation, and butterfly plate realizes that by rotation in 90 ° of scopes the full runner of fire-fighting butterfly valve opens and closes function.In this process, the indicator board on the live axle all the time with the butterfly plate synchronous rotary, but the just switching degree of fire-fighting butterfly valve as can be known of distant surveillance indicator board.
In addition, when groove fire-fighting butterfly valve was connected with pipeline, clip was by bolt and nut check, and the seal ring in the clip recess is squeezed and tightly binds round at valve body and pipe joint place, seals.Simultaneously, the limit mouth at clip two ends imbeds respectively in valve body groove and the pipeline groove, thereby groove fire-fighting butterfly valve and pipeline are linked together.
The invention has the advantages that:
1, the valve body inner and outer surface is coated with the molding powder layer, the sealing pair that forms of the rubber layer of valve seat molding powder layer and butterfly plate outer cladding wherein, and it is simple in structure, and material and processing cost are low, and full runner good sealing effect.
2, live axle is connected the structural type that adopts flat square toes to cooperate with attachment hole with butterfly plate, flat square toes also and between the attachment hole have certain gap in attachment hole, this is a kind of rigidly connected kind of drive that do not have, it is simple in structure, novel in design, assembly technology is simple, and transmission performance is good, and butterfly plate has Self-centering Action when closing in valve body.
3, the vertical live axle top that is loaded on of indicator board is positioned at driver top, with the butterfly plate synchronous rotary, but the just switching degree of fire-fighting butterfly valve as can be known of distant surveillance indicator board.
When 4, groove fire-fighting butterfly valve and pipeline are installed, only need its groove end is alignd with pipe joint groove end, convenient and swift when installing so at the construction field (site) with clip engaging, the nut on tighting a bolt, simultaneously, also can exempt the corrosive pipeline that causes because of welding.
5, the seal ring that is equipped with at its groove end and pipe joint groove end place of groove fire-fighting butterfly valve is not even pipeline can produce leakage because external load produces certain angle excursion yet.
