Description
Technical field
The utility model belongs to automobile exhaust gas purifying technical field, and in particular to a kind of novel pressure difference seal of tube connection structure
Grain catcher assembly.
Background technology
Grain catcher, that is, DPF is a kind of filter in the diesel engine emissions system, during use by
DPF is easily led in reasons such as poor quality fuel oils and blocks failure, tail gas can not be not only filtered, also oil consumption be made to increase, and engine performance is disliked
Change, or even damage engine, so need constantly to monitor the pressure of the filter assemblies both sides of DPF, find to block carry out in time it is clear
It washes or replaces；The pressure difference pipe of filter assemblies both sides setting is the channel for monitoring pressure, keeps air-flow between pressure difference pipe and DPF unimpeded
It is the key that ensure monitoring result accuracy, is found in long-term working practice, since pressure difference pipe and DPF is welded seal
, commissure easily blocks, and causes monitoring result inaccurate, and be difficult to be cleared up, therefore researches and develops this programme.
Invention content
Purpose of the utility model is to solve the above problems existing for grain catcher, provide a kind of novel pressure difference
The grain catcher assembly of seal of tube connection structure, its technical solution is as follows：
A kind of grain catcher assembly of novel pressure difference seal of tube connection structure, it includes filter assemblies, air intake assembly, row
The both ends of pneumatic module and pressure difference pipe, filter assemblies are respectively arranged with air intake assembly and gas deflation assembly, air intake assembly and gas deflation assembly
It is connected to respectively with a pressure difference pipe；Be both provided with intubation pedestal on air intake assembly and gas deflation assembly, every pressure difference pipe respectively with
Corresponding intubation pedestal grafting；Pressure difference pipe uses Bundy tube；A bolt is set on pressure difference pipe, pressure difference pipe is matched with bolt rotation
It closes；The inserted terminal of pressure difference pipe is provided with the ripple pier nose of evagination, is provided with pressing plate between ripple pier nose and bolt, pressing plate with
Pressure difference pipe is fixedly connected, bolt with intubation base thread connect, be intubated pedestal in be provided with the screw hole coordinated with bolt and with
The stomata of screw hole connection, the hole diameter are less than the opening diameter of ripple pier nose, and the reach of bolt is more than intubation base
The length of seat inner bolt hole, when screwing bolts, ripple pier nose is pressed on the stomata edge and reaches sealing effect by bolt pusher pressing plate
Fruit；In order to make ripple pier nose have sufficient elastic deformation space, annular groove is provided between the screw hole and stomata；In order to
Increase sealed faying face product, intermediate incline is set between the annular groove and stomata.
The beneficial effects of the utility model are：Pressure difference pipe uses Bundy tube, and Bundy tube is by thin-walled steel plate through pipe crimping, high temperature
Soldering, the techniques such as zinc-plated are process, soft and flexible, have many advantages, such as easily molded, and vibration resistance is tired, high pressure resistant, with
Screw thread compresses mode and is sealedly connected on air intake assembly and gas deflation assembly, not only ensures that sealing effect and internal gas flow are unimpeded, also
Cleaning easy to disassemble ensures that monitoring result is accurate.
