Abstract
The utility model discloses a welding neck flange of petrochemical industry pump installation usefulness, including being the body that ring form set up, the center of body is provided with the water conservancy diversion passageway, and the body corresponds the connecting hole that water conservancy diversion passageway outside position was provided with a plurality of quantity, and the photogenic periphery axial to the water conservancy diversion passageway in a side end face of body is connected and is provided with toper welded connection pipe, the body be provided with the scrobicular ring that converges around toper welded connection pipe a week for the outer wall base department of toper welded connection pipe, be provided with mutual central symmetry of multichannel and outer end on the scrobicular ring that converges and be located the water drainage tank on the body circumference wall, water drainage tank be the arc, and water drainage tank's the degree of depth deepens to set up to the outer end from its the inner gradually. The utility model has the advantages that can reduce the water droplet that condenses flows in in the connecting hole.
Description
Technical field
This utility model relates to a kind of W.N flange, specifically refers to the W.N flange that petrochemical industry pump is installed.
Background technology
Petrochemical industry pump (petrochemical industry pump) is for oil and the spcific power equipment transported of inflammable, explosive, the poisonous or valuable medium of chemical field.Existing petrochemical industry pump typically all uses W.N flange to carry out installation with pipeline to be connected, to ensure sealing when mounted.
The structure of existing W.N flange generally includes the body in circular setting, body be provided centrally with flow-guiding channel, body correspondence flow-guiding channel outer fix is provided with a number of connecting hole, it is provided with boss on the axial end face of body, it is provided with taper connection pipe on the axial other end of body, during use, the side being correspondingly arranged on boss of W.N flange and the Flange joint on petrochemical industry pump, taper connection tube and tube welds mutually.
Owing to petrochemical industry pump is the most all installed on open air, the surface of W.N flange there will be condensation vapor at night, on the other hand, due to when W.N flange docks with the flange on petrochemical industry pump all be use screw bolt and nut dock, the water droplet being condensed on W.N flange is often flowed into inside the connecting hole at bolt place, thus cause bolt to get rusty in connecting hole, and then bring much inconvenience to the dismounting maintenance of bolt.
Utility model content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art to exist, and provides a kind of W.N flange that can reduce the petrochemical industry pump installation that the water droplet condensed is flowed in connecting hole.
For achieving the above object, the technical solution of the utility model is to include the body in circular setting, body be provided centrally with flow-guiding channel, body correspondence flow-guiding channel outer fix is provided with a number of connecting hole, on one side end face of body, the periphery relative to flow-guiding channel is axially connected with taper welding connecting tube, described body is relative to being provided with around the taper welding connecting tube scrobicular ring that confluxes of a week at the outer wall base of taper welding connecting tube, conflux and be provided with the mutual centrosymmetry of multiple tracks on scrobicular ring and outer end is positioned at the rhone in body circumferential wall, described rhone is curved, and the degree of depth of rhone from its inner the most gradually deepen arrange.
By this setting, the water droplet being condensed on taper welding connecting tube is collected by the bulge loop that confluxes, and is then flowed out from body by water droplet by rhone, thus reduce water droplet and enter in connecting hole, get rusty reducing bolt, and this setting, multiple rhones are centrosymmetric setting, do not interfere with the weight distribution of body, the gravitational equilibrium contributing to maintaining body is constant, it addition, rhone camber is arranged, the infringement of the stress structure to body, reasonable in design can be reduced.
Arranging the connecting hole being described further and include four, and these four connecting hole circumference uniform distributions are on body, described rhone is also equipped with four roads, and per pass rhone is distributed between adjacent two connecting hole.By this setting, structure arranges more reasonable, and gravitational equilibrium is good.
Below in conjunction with specification drawings and specific embodiments, this utility model is described further.

Detailed description of the invention
Below by embodiment, this utility model is specifically described, is served only for this utility model is further described, it is impossible to be interpreted as the restriction to this utility model protection domain.
Detailed description of the invention of the present utility model as Figure 1-3, including the body 1 in circular setting, body 1 be provided centrally with flow-guiding channel 11, body correspondence flow-guiding channel outer fix is provided with a number of connecting hole 12, on one side end face of body 1, the periphery relative to flow-guiding channel is axially connected with taper welding connecting tube 13, described body 1 is relative to being provided with around the taper welding connecting tube scrobicular ring 14 that confluxes of a week at the outer wall base of taper welding connecting tube 13, conflux and be provided with the mutual centrosymmetry of multiple tracks on scrobicular ring 14 and rhone 15 that outer end is positioned in body circumferential wall, described rhone 15 is curved, and the degree of depth of rhone 15 from its inner the most gradually deepen arrange.
It addition, the connecting hole 12 described in the present embodiment includes four, and these four connecting hole 12 circumference uniform distributions are on body, and described rhone is also equipped with four roads, and per pass rhone 15 is distributed between adjacent two connecting hole.
Claims (2)
1. the W.N flange that a petrochemical industry pump is installed, including the body in circular setting, body be provided centrally with flow-guiding channel, body correspondence flow-guiding channel outer fix is provided with a number of connecting hole, on one side end face of body, the periphery relative to flow-guiding channel is axially connected with taper welding connecting tube, it is characterized in that: described body is relative to being provided with around the taper welding connecting tube scrobicular ring that confluxes of a week at the outer wall base of taper welding connecting tube, conflux and be provided with the mutual centrosymmetry of multiple tracks on scrobicular ring and outer end is positioned at the rhone in body circumferential wall, described rhone is curved, and the degree of depth of rhone from its inner the most gradually deepen arrange.
