Abstract
The patent relates to a tube section for preventing a drain line from returning odour, which is made of stainless steel or steel quality material plated with an antirust coat, and comprises a tube section, a retaining valve plate and a balancing pole. An axle hole on an inner wall of the tube section is used for installing the retaining valve plate; and a baffle plate on the inner wall of the tube section not only limits the equilibrium position of the valve plate, but also tightly attaches to the valve plate, to lead the sealing effect of the tube section to be better. When the tube section does not drain, the retaining valve plate stays in a closure state due to the deadweight of the balancing pole and tightly attaches to the baffle plate on a tube wall; when in drainage, the retaining valve plate inside the tube section is thrust aside due to the water weight, and wastewater flushes into a sewage line; and after drainage, the valve plate turns back automatically due to the balancing pole, tightly attaches to the baffle plate on the tube wall, and seals up the sewage line, so as to serve the purpose for preventing the sewage line from upwards returning the odour. Compared with the traditional water return joint, the tube section leads the drainage to be more unblocked and the installation to be more convenient, in addition, the response is nimble and the leak tightness is good, and the tube section can effectively prevent the drain line from returning the odor upwards.
Description
Technical field:
The utility model relates to a kind of tube coupling of drainage pipe, and particularly a kind of drainage pipe that prevents returns the tube coupling of peculiar smell.
Technical background:
At present, the most of drainage pipes of China all are to prevent to return on the peculiar smell of sewer pipe by the method that adopts water bending.But use water bending that following shortcoming is arranged: one, resistance of water drainage is big, is unfavorable for rapid draining; Two, volume is big relatively; Three, joint is many, and as using at exposed parts such as kitchen vegetable sink discharge pipes, seepage is installed also trouble easily; Four, water bending is that the water that relies on its inside to stockpile reaches and prevents the effect returned on the peculiar smell, if water overlong time in the water bending, when indoor air temperature would be too high, easy breed bacteria also produces new peculiar smell, but,, do not reach again and prevent the purpose returned on the peculiar smell if do not stockpile water in the water bending.
Summary of the invention:
The utility model is the deficiency that exists in the above-mentioned technology, and a kind of tube coupling that prevents to return on the drainage pipe peculiar smell is provided.
Tube coupling described in the utility model is made by the steel material of stainless steel or plating antirust coat, and there is screw thread the termination, can be screwed in the drainage pipe easily.It is made up of tube coupling, check valve sheet and balancing pole, it is characterized in that: the tube coupling inwall is equipped with axis hole, rotating shaft is installed on the axis hole, check valve sheet is installed in the rotating shaft, the both sides of tube coupling inwall are equipped with baffle plate, both limited the equilbrium position of valve block, closely sticked together with valve block again, and made the tube coupling sealing effectiveness better.During installation, this tube coupling is screwed between drainage pipe and the drainage inlet (as outfall such as vegetable sink, washbowls), this tube coupling relies on the deadweight of balancing pole when being in non-displacement condition, make check valve sheet be in closure state, and be close to the baffle plate on the tube wall.When draining, rely on the weight of water, tube coupling internal check valve sheet is washed open, waste water pours sewer pipe, and after having arranged water, valve block relies on the balancing pole automatic homing, be close on the baffle plate on the tube wall, the sealed sewer pipe road reaches and prevents the purpose returned on the sewer pipe peculiar smell.
When operating principle of the present utility model is draining, utilize the gravity of institute's effluent to destroy check valve sheet both sides equilibrium state, open check valve sheet; After the water emptying, utilize the balancing pole deadweight to make check valve sheet return to closure state, the angle of balancing pole and check valve sheet is 60 °.The equilibrium state of valve block is very faint, and any point external force all can be destroyed its balance.The comprehensive moment of an end that has balancing pole is only little by little big than the comprehensive moment of the valve block other end, because valve shaft is not placed in the middle, is in the position of tube coupling 1/2 radius, so, during draining, produced unbalanced moment, guaranteed that valve block can in time open.
More traditional water bending, tube coupling of the present utility model not only makes draining more unimpeded, and installation simultaneously is also more convenient, only needs to be linked into upright sewer pipe to tube coupling with screw thread and gets final product, and be quick on the draw, good airproof performance, can effectively prevent to return on the gutter peculiar smell.
Description of drawings:
Fig. 1 is vertical cross section figure of the present utility model
Fig. 2 is hull-borne figure of the present utility model
Fig. 3 is the A-A sectional drawing of Fig. 1
Fig. 4 is check valve sheet figure
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
By Fig. 1-2 as can be known, the tube coupling inwall is equipped with axis hole, and rotating shaft 1 is installed on the axis hole, and check valve sheet 4 is installed in the rotating shaft 1, and the both sides of tube coupling inwall are equipped with baffle plate 2, have both limited the equilbrium position of valve block, closely stick together with valve block again, make the tube coupling sealing effectiveness better.During installation, this tube coupling is screwed between drainage pipe and the drainage inlet (as outfall such as vegetable sink, washbowls), this tube coupling relies on the deadweight of balancing pole 3 when being in non-displacement condition, make check valve sheet 4 be in closure state, and be close to the baffle plate 2 on the tube wall.When draining, rely on the weight of water, tube coupling internal check valve sheet 4 is washed open, waste water pours sewer pipe, and after having arranged water, check valve sheet 4 relies on balancing pole 3 automatic homings, be close on the baffle plate 2 on the tube wall, the sealed sewer pipe road reaches and prevents the purpose returned on the sewer pipe peculiar smell.
