Description
One, technical field
The utility model relates to the shutoff leather cup technical field that pipe pressurized shutoff is used, and is a kind of dovetail lip shutoff leather cup.
Two, background technique
In the repairing of pipeline or when connecting, for the ease of quick organizing construction, often need immediately pipeline to be implemented shutoff, at present general normal employing pipeline machinery non-stop plugging technology is carried out shutoff to pipeline, because it has that feasibility is good, safety, economy, rapidly and efficiently, be usually used in jobs that requires special skills such as the maintenance of in-service pipeline and repairing.Pipeline machinery non-stop plugging, be exactly when pipe laying, install the shutoff threeway that has service hatch and sandwich valve in advance between two segment pipes, sandwich valve is installed in the outlet of service hatch, the sandwich valve of cutting out has sealed service hatch, makes pipeline can keep sealing proper functioning; When needs shutoff operation, on sandwich valve, install plugging device, be connected with a block head that can turn to by connecting rod on the plugging device, by connecting rod block head is sent to pipe interior from service hatch after opening sandwich valve, turn to behind the inwall of block head contact pipeline then, the inwall of block head after turning to by its anterior rubber cup and pipeline fits tightly and keeps sealing, and the inner chamber of pipeline blocks fully the most at last; When needs cancellation shutoff, only need block head to be mentioned withdrawal and make pipeline recover unimpeded by connecting rod, behind the last closed clip plate valve, can take off plugging device.But the rubber cup of existing plugging device has the following disadvantages in actual use: because of the outer side surface that has rubber cup now is comparatively level and smooth conical surface, when the rubber cup shutoff volute that uses plugging device, vertical masonry joint pipe, liquid takes place from the weld joint easily to leak and shutoff is failed; In addition, when foreign material such as iron dirt, iron filings are arranged in the pipeline, also influence plugging effect easily.
Three, summary of the invention
The utility model provides a kind of dovetail lip shutoff leather cup, the problem that its rubber cup that has solved existing plugging device comparatively smoothly causes easily the weld seam because of the iron dirt in the pipeline or iron filings and volute or vertical masonry joint pipe to leak because of outer side surface.
The technical solution of the utility model realizes by following measure: a kind of dovetail lip shutoff leather cup, comprise leather cup body and outer seal lip, the leather cup body comprises circular connecting plate and sealing outer rim, the middle part of leather cup body is circular connecting plate, there is sealing outer rim in the form of a ring the outer end of circular connecting plate, the outer side surface of sealing outer rim is the narrow cone surface of bit in the left wide right side, sealing outer rim left side has and extends the outside, the sealing outer rim left side and the rigidity outer seal lip greater than the sealing outer rim, the inner of outer seal lip and circular connecting plate are connected as a single entity, and form the V-ring sky between the left surface of the right flank of outer seal lip and sealing outer rim.
Be further optimization and/or improvements below to above-mentioned model utility technological scheme:
The left surface of above-mentioned V-ring sky and the angle of right flank can be 12 degree.
The left surface of above-mentioned sealing outer rim and the angle between the cone surface of bit can be 30 degree.
The left surface of above-mentioned outer seal lip and the left surface of circular connecting plate can form 160 degree angles.
The left surface of above-mentioned outer seal lip and the right flank of outer seal lip can form 24 degree angles.
Can there be the outer lip end face outer end of above-mentioned outer seal lip, and the left surface of outer lip end face and outer seal lip can form 63 degree angles, and the right-hand member of outer lip end face can be 5 millimeters with the distance of sealing outer rim left end.
The utility model reasonable and compact in structure, easy to use, it is by increasing the outer seal lip that forms the V-ring sky with the sealing outer rim in the former leather cup body outside, by the radial support effect of outer seal lip to the sealing outer rim, the sealability of shutoff leather cup be can significantly improve, iron dirt, iron filings and volute and vertical masonry joint pipe are particularly useful for having in the pipeline.
Four, description of drawings
Accompanying drawing 1 is looked the sectional structure schematic representation for the master of the utility model most preferred embodiment when nature.
Accompanying drawing 2 is the local structure for amplifying schematic representation at A place in the accompanying drawing 1.
The master in working order the time looks the sectional structure schematic representation for the utility model most preferred embodiment for accompanying drawing 3.
Coding in the accompanying drawing is respectively: 1 is outer seal lip, and 2 is circular connecting plate, and 3 are the sealing outer rim, and 4 is cone surface of bit, and 5 is the V-ring sky, and 6 is the outer lip end face.
Five, embodiment
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
As accompanying drawing 1, shown in 3, this dovetail lip shutoff leather cup comprises leather cup body and outer seal lip 1, the leather cup body comprises circular connecting plate 2 and sealing outer rim 3, the middle part of leather cup body is circular connecting plate 2, there is sealing outer rim 3 in the form of a ring the outer end of circular connecting plate 2, the outer side surface of sealing outer rim 3 is the narrow cone surface of bit 4 in the left wide right side, sealing outer rim 3 left sides have and extend the outside, sealing outer rim 3 left sides and the rigidity outer seal lip 1 greater than sealing outer rim 3, the inner of outer seal lip 1 and circular connecting plate connect 2 and are one, form V-ring sky 5 between the left surface of the right flank of outer seal lip 1 and sealing outer rim 3.V-ring sky 5 makes sealing outer rim 3 that bigger deformation space be arranged, and the rigidity justice of outer seal lip 1 can play the radial support effect to sealing outer rim 3 in the back that is squeezed greater than sealing outer rim 3, thereby can significantly improve the sealability to pipeline.The external diameter of outer seal lip 1 is bigger than the external diameter of leather cup body, and outer seal lip 1 is that one of percentage of internal diameter of the pipeline is to 2 percent with respect to the magnitude of interference of the internal diameter of the pipeline of its shutoff.
