Abstract
The utility model relates to a flange, in particular to an embedded type steel plastic flange which comprises a flange plate and a flange sealing body. The outer surface of the flange sealing body is provided with a sawtooth-shaped anti-dropping catching groove. According to the embedded type steel plastic flange, the outer surface of the flange sealing body is provided with the sawtooth-shaped anti-dropping catching groove, a tube is assembled with the sealing body after heated, and the tube can be closely attached to the sealing body after cooled, and therefore the tube is prevented from coming off the sealing body when carried and transported, and sealing is reliable due to function of pressure after connection. The flange plate can rotate, and is convenient to install, firm in connection and reliable in utilization.
Description
Technical field
The utility model relates to a kind of flange, is specifically related to a kind of built-in steel plastic flange.
Background technique
Flange is the interconnective parts such as pipe and pipe, valve, pipe fitting, is connected in pipe end.With bolt hole, use bolted flange during use on the flange, seal with liner between the sealing surface.
Injection molded flange of the prior art is generally bonding or is welded to connect, because flange root (flange cylinder) strength of materials and pipe material intensity there are differences, bonding not prison welding is solid, (under coal mine) easily causes the flange root to damage under the particular surroundings, the interior medium of pipe is easily revealed after using, and causes unnecessary loss.
The model utility content
According to above deficiency of the prior art, technical problem to be solved in the utility model is: a kind of built-in steel plastic flange is provided, have easy for installation, be connected firmly, the service-strong characteristics.
The technological scheme that its technical problem that solves the utility model adopts is:
Built-in steel plastic flange described in the utility model comprises flange plate and flange seal body, and the flange seal external surface is processed with band saw dentation Drop-proof catching groove.
The profile of described flange seal body is taper type.
The steel-plastic flange seal embedded in the tubing when characteristics of the utility model maximum were use, owing on the external side of flange seal band saw dentation Drop-proof catching groove being set, and also can form corresponding catching groove after the tubing heating, and therefore in conjunction with tightr, difficult drop-off during use.Flange seal external surface and tubing are closely linked, need not bonding or welding.The flange seal body be shaped as taper type, the requirement of seal face size conforms GB.
During use, adopt flaring machine that built-in steel plastic flange and tubing are connected as a single entity by heating, cooling rear flange seal intimate is embedded on the internal surface of pipe; Then flange plate is enclosed within on the tubing, after being fixedly connected with bolt, can comes into operation.
Described tubing comprises pipe, pipe fitting, valve etc.Seal body material can be selected different materials according to demand, such as stainless steel, carbon steel, cast iron, pottery etc.; The material of tubing is such as UPVC, PVC-M, CPVC, HDPE, PPR etc.; Flange plate can be selected different materials according to demand, such as overall plastic, stainless steel, carbon steel etc.
The beneficial effect that the utility model has is:
Seal outer surface of the present utility model is processed with band saw dentation Drop-proof catching groove, tubing heats rear and the seal assembling, tubing closely is fitted on the seal after the cooling, avoids tubing in carrying, reach when using and come off with seal in transit, after connecting since the pressure-acting sealing reliably.Flange plate is rotatable, and is easy for installation, is connected firmly, and uses reliable.
Description of drawings
Fig. 1 is the utility model flange seal body structure schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is that the utility model uses view.
Among the figure: 1, flange seal body; 2, Drop-proof catching groove; 3, flange plate; 4, tubing.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Shown in Fig. 1 ~ 3, built-in steel plastic flange described in the utility model comprises flange plate 3 and flange seal body 1, and flange seal body 1 outer surface is processed with band saw dentation Drop-proof catching groove 2, and the profile of flange seal body 1 is taper type.
Using method:
During use, adopt flaring machine that built-in steel plastic flange and tubing 4 are connected as a single entity by heating, cool off rear flange seal 1 intimate and be embedded on tubing 4 internal surfaces; Then flange plate 3 is enclosed within on the tubing 4, after being fixedly connected with bolt, can comes into operation.
Selection:
When the characteristics of the utility model maximum are use steel-plastic flange seal 1 is embedded in the tubing 4, owing to being processed with band saw dentation Drop-proof catching groove 2 on flange seal body 1 outer side surface, and also can form the catching groove of respective shapes after tubing 4 heating, and therefore in conjunction with tightr, difficult drop-off during use.Described tubing 4 comprises pipe, pipe fitting, valve etc.
Seal 1 outer surface of the present utility model is processed with band saw dentation Drop-proof catching groove 2, tubing 4 heats rear and seal 1 assembling, tubing 4 closely is fitted on the seal 1 after the cooling, avoid tubing 4 in carrying, reach when using and come off with seal 1 in transit, after connecting since the pressure-acting sealing reliably.Flange plate 3 is rotatable, and is easy for installation, is connected firmly, and uses reliable.
Claims (2)
1. a built-in steel plastic flange comprises flange plate and flange seal body, it is characterized in that: the flange seal external surface is processed with band saw dentation Drop-proof catching groove.
2. built-in steel plastic flange according to claim 1, it is characterized in that: the profile of described flange seal body is taper type.
