Description
Technical field
It is used for indoor noise-reducing drain pipe road structure, i.e., bowl of a kind of up concave type with the flexible thorn of pressure the present invention relates to a kind of
Shape structural pipeline part, indoor UPVC soil stacks and transverse tube junction are installed on, to buffer in soil stack current to transverse tube
The impact of tube wall, noise is reduced, belongs to drainage system technical field.
Background technology
UPVC drainpipes are taken with its smooth inwall, good drainage performance, lightweight practicality and convenient the advantages of installing
For traditional iron drain-pipe, architecture indoor is widely used in.However, as people carry to living environment requirement
Height, UPVC drainpipes the noise problem of band turned into modern architecture and house living needs considers and solved the problems, such as.
Noise caused by soil stack is one of principal element of drainage pipeline noise.At present, a good building is set
Meter scheme from drainage system and drainage pipeline in building body and indoor arrangement from the point of view of noise problem, such as draining system
System is designed as double profile tube drainaging system, that is, balances the positive and negative air-pressure in standpipe, reduce gas lock；Homofloor drainage system, i.e., only
There is soil stack to pass through floor.For another example soil stack will not be arranged on the adjacent wall of living room, bedroom and operating room, as much as possible
It is arranged in piping shaft.However, this also can only be to reduce noise to a certain extent.
Standpipe reclaimed water stream dropping process forms rotary water film layer and air-flow plug, both states drastically change, made in standpipe
Air pressure rapid fluctuations send noise, while current hit with draining tube wall and also trigger vibration noise.When riser length is larger,
Especially UPVC soil stacks and transverse tube junction, drain discharge and flow velocity are bigger, and caused noise is bigger.
At present, to solve the noise problem of drainage pipeline, a variety of noise reduction tubing are developed, such as inner helix pipe, double
Wall vacuum tube, foamed sandwich pipe, sandwich tube etc..
There is the inner helix pipe of helix distribution rib in pipe, its rib structure plays guide functions to the moisture film of rotation, can be with
Make the flow velocity for being close to the current layer that tube wall moves downward relatively reduced, the UPVC that caused noise is less than common smooth inner wall is managed.
However, when standpipe caliber is larger or water velocity is larger, in addition to the very thin one layer of current for being close to tube wall, current main body still with compared with
Big flow velocity impacts to the transverse tube of riser bottom, does not there is obvious noise reduction.
The noise reducing pipes such as double walled vacuum pipe, foamed sandwich pipe, sandwich tube are the porous knots formed using hollow or core layer foaming
Structure plays a part of sound insulation and sound-absorbing, caused noise during so as to reduce draining.However, drainage pipeline is produced by the impact of water
Raw vibration inherently sound source, hollow or foaming structure are smaller due to the quality of tubing, it is easier to and it is vibrated to send noise,
Therefore in actual test, the noise reduction of some two-wall hollow tubing and foamed core layer pipe be not it is highly desirable, it is caused
Noise is even greater than the UPVC pipes of common smooth inner wall.
The content of the invention
For soil stack and this big problem of transverse tube junction noise, the present invention provides one kind and is used for indoor noise reduction draining
Pipeline configuration, to solve shock problem of the current main body of high-speed motion to riser bottom transverse tube, and then reduce soil stack with
The noise of transverse tube junction.
The technical solution adopted for the present invention to solve the technical problems is：
The threeway of soil stack and transverse tube junction or bend pipe tools are replaced with into a kind of novel pipe fitting, the main pipe body is
Bowl structure device of the up concave type with the flexible thorn of pressure, can play a part of reducing main body water velocity.Include in its device
Pressure is stretched thorn, ring wedge block, seal cover board, and trace, flexible steel ring, bearing plate are included outside device.
Above-mentioned bowl-shaped body constructional device is in back taper, and wall and common threeway or elbow wall are integral, face standpipe
Lower exit." the rim of a bowl " cover is equal with inwall on the downside of common threeway or bend horizontal section, i.e., whole bowl structure and common three
Logical or elbow is connected, and main structure body prevents take up pipeline internal fluid channels.
The flexible thorn of above-mentioned pressure, positioned at bowl-shaped body constructional device center.Slided for back taper the flexible thorn the latter half of pressure
Block, in inverted pyramid or turbination, but it should match with above-mentioned wedge block.The flexible thorn top half of pressure is single beam or multi beam
Acanthosome, acanthosome root and tip are in certain slope.
Above-mentioned ring wedge block is rigid, positioned at the flexible thorn back taper sliding block periphery of pressure.Ring wedge block is upper and lower
Surface is horizontal plane；It is close to the one side of the flexible thorn of pressure for tapered plane or tilts cambered surface, but should be with the flexible thorn of above-mentioned pressure
Back taper sliding block matches；The one side for being close to bowl-shaped body structure wall is inclination cambered surface.Wedge block can stretch in pressure
Slided up and down in space between thorn back taper sliding block and bowl-shaped body structure wall.
Above-mentioned trace is rigid straight-bar, and quantity is multiple, is uniformly distributed and wedge block upper surface is fixed in bottom.Interlock
Bar circular in cross-section, ellipse, sector or parallelogram.
Above-mentioned seal cover board is fixed on wedge block, fixed between cover plate and trace and sealing.Seal cover board with it is bowl-shape
Seal washer is provided between main structure body inwall, the seal washer of elastic circle mouth, pad are provided between seal cover board and the flexible thorn of pressure
Circle can prevent current and solid matter from entering inside bowl structure device.
Above-mentioned flexible steel ring is stainless steel, is horizontally mounted.Soil stack tube wall is fixed in steel ring one end, and the other end is solid
At the centre of form of bearing plate bottom surface.
Above-mentioned bearing plate is rigid plate, and quantity is multiple and identical with trace quantity, above trace.Bearing plate one
Soil stack tube wall is fixed at end, and the position of form center of bearing plate is connected with flexible steel ring.Bearing plate is plane or cambered surface, in rule
Shape or abnormity.
Compared with prior art, bowl structure device of the up concave type of the present invention with the flexible thorn of pressure is stood by being fixed on draining
The bearing plate sensing water flow pressure of pipe, and interlock ring wedge block is upper and lower slides extruding and the flexible thorn of release pressure, be lifted or
The main body current that can effectively disperse in soil stack of flexible thorn declined, slow down its flow velocity, and along the overland flow of flexible thorn
To dewatering horizontal tube, the structure can largely reduce the noise of soil stack and transverse tube joint.
The beneficial effects of the invention are as follows come with a kind of bowl structure conduit component of special up concave type with the flexible thorn of pressure
Instead of common threeway or elbow, while UPVC soil stacks can be reduced with transverse tube junction current to caused by tube wall impact
Noise.Its apparatus structure is simple, positive effect, is easily installed and practical application, great Technique Popularizing prospect.
