Abstract
The utility model discloses a pressure bearing type hand-operated exhaust device. The pressure bearing type hand-operated exhaust device comprises a tube shell installed on an exhaust port of a pipeline, and an adjustment end cap which is matched with the tube shell, wherein an inner threaded hole is formed in the inner wall of the outer side of the tube shell, a plurality of air discharge ducts are formed in the inner threaded hole in the circumferential direction, the adjustment end cap is installed on the inner threaded hole through threads, a conical squeezing surface is arranged on the front portion of the adjustment end cap, a conical sealing surface, which is matched with the conical squeezing surface of the adjustment end cap, is arranged on the inner wall of the tube shell, on the root portion of the inner threaded hole, and a horn-mouth-shaped metal sealing piece is arranged between the conical sealing surface and the conical squeezing surface of the adjustment end cap. According to the pressure bearing type hand-operated exhaust device, due to the adoption of the horn-mouth-shaped metal sealing piece, the sealing performance of the exhaust device can be effectively improved, the metal sealing piece has the advantages of being resistant to high pressure and high temperature and extremely high in tenacity and malleability, in this way, the service life of the sealing piece can be longer when the sealing piece is used in changeable environments with high temperature, low temperature, high pressure and low pressure, the exhaust device can be used repeatedly, and cost is reduced.
Description
Technical field
The utility model relates to a kind of pipeline air exhaust water pressure release sealing technique, particularly a kind of pressure-bearing type manual exhaust device that is applicable to high-temperature pipe.
Background technique
What existing pressure-bearing type manual exhaust device Sealing adopted is rubber, plastics and other nonmetallic material, this material is in use because external force (axle power) causes resiliently deformable, all larger in order to reach the common axle power adopting of better sealing, the distortion of material will be more obvious like this, and in high temperature low temperature changing environment, be easy to cause sealed mouth leakage phenomenon because of heatproof and the bad problem of withstand voltage properties of material for a long time.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of pressure-bearing type manual exhaust device of reasonable in design, easy to use, good sealing effect is provided.
Technical problem to be solved in the utility model is to realize by following technological scheme, the utility model is a kind of pressure-bearing type manual exhaust device, be characterized in: comprise the shell being contained on row of conduits gas port and the adjusting plug coordinating with shell, the inwall in described shell outside is provided with internal thread hole, on internal thread hole, be provided with several air vents along circumferential direction, described adjusting plug is contained on internal thread hole by screw thread, regulate the front portion of plug to be provided with tapered squeezing face, on the inner wall of tube shell of internal thread hole root, be provided with and the conical seal (contact) face that regulates the tapered squeezing face of plug to coordinate, between conical seal (contact) face and the tapered squeezing face of adjusting plug, be provided with toroidal metal seal.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described shell is locknut joint.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and the inner outer wall of locknut joint is provided with outside thread.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described air vent is provided with four, is evenly distributed on internal thread hole.
Compared with prior art, the utility model adopts toroidal metal seal can effectively improve the sealing of venting gas appliance, solves the pressure-resistant seal problem of venting gas appliance in high temperature low temperature changing environment; Toroidal metal seal can embody the principle of " splitting in mechanics " contact, coupling mechanism force forms the sealing perpendicular to the greater role power of sealing surface, so metal seal reaches good sealing with conical seal (contact) face under very little axle power effect, the material resiliently deformable that little axle power causes will be less, like this will be more of a specified duration on working life; Anticorrosive, high temperature resistant, extremely strong toughness that metal seal has, the strong feature of ductility, in the changeable environment of high temperature low temperature, will the working life of Sealing more of a specified duration like this, and this venting gas appliance can reuse, and save cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of shell.
Embodiment
Referring to accompanying drawing, further describe concrete technological scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2, a kind of pressure-bearing type manual exhaust device, comprise the shell 1 being contained on row of conduits gas port and the adjusting plug 3 coordinating with shell 1, the inwall in described shell 1 outside is provided with internal thread hole 6, on internal thread hole 6, be provided with several air vents 5 along circumferential direction, described air vent 5 can be provided with four, is evenly distributed on internal thread hole 6.
Described adjusting plug 3 is contained on internal thread hole 6 by screw thread, regulate the front portion of plug 3 to be provided with tapered squeezing face 4, on shell 1 inwall of internal thread hole 6 roots, be provided with and the conical seal (contact) face that regulates the tapered squeezing face 4 of plug 3 to coordinate, between conical seal (contact) face and the tapered squeezing face 4 of adjusting plug 3, be provided with toroidal metal seal 2.Toroidal metal seal 2 can be annealed red copper part.
Use while installation, first toroidal metal seal 2 is put in internal thread hole 6, then regulating plug 3 levels to be slowly screwed in the internal thread hole 6 of shell 1, by the tapered squeezing face 4 that regulates plug 3, toroidal metal seal 2 is pressed on the conical seal (contact) face in shell 1.In the time of needs exhaust, manually unscrew and regulate plug 3, between metal seal 2 and conical seal (contact) face, will form gap, ducted gas is out discharged by the air vent 5 on internal thread hole 6 from this gap.While not needing exhaust, adjusting plug 3 is tightened.
Described shell 1 is locknut joint, and the inner outer wall of locknut joint is provided with outside thread, can be screwed on row of conduits gas port by outside thread, also can directly be welded on row of conduits gas port.
Claims (4)
