Abstract
The utility model discloses a novel structural style of installation pitot tube subassembly, including the section of intaking, one side of the section of intaking is fixed with the export through the bolt and is taken over, one side of taking over in the export is fixed with pitot tube (pressure manifold) subassembly through special design's nut, the excircle department of pitot tube subassembly is provided with prevents changeing the parallel key, locking mechanism contains lock nut, lock nut end face design has the cross recess, and its function is various.
Description
Technical Field
The utility model relates to a pitot tube technical field especially relates to a novel structural style of installation pitot tube subassembly.
Background
The pitot tube pump is a novel low-flow high-pressure pump with unique structure and working principle, belongs to a pump with extremely low specific revolution, and can be used in various fields of petrochemical industry, papermaking, boiler water supply and the like; two pitot tube pumps are introduced from the United states for the first time in China ten years ago and are used for conveying raw oil of a carbon black production line, and the pitot tube pumps are obviously superior to other types of pumps in the aspects of stable operation, service life and the like. At present, the pitot tube of the pitot tube pump is tightened by adopting a plurality of screw fixing ways on the circumference, and the theory of the fastening way is feasible, but the practice finds that: 1. the movable equipment has vibration, and the screw is soaked in a medium for a long time, so that the movable equipment is easy to loosen, and the phenomenon that the pump cannot be disassembled due to screw corrosion occurs; 2. when the pitot tube component is installed, a specific assembling and disassembling tool is needed to guide the pitot tube component to enter the water inlet section for fixing, so that an internal thread is inevitably arranged, if the fixing mode of the pitot tube component is designed to be a tightening mode of a plurality of screw fixing modes on the circumference, the pitot tube component is completely unnecessary, and the pitot tube component is not in accordance with the optimized and simple design concept.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a novel structural form for installing a pitot tube component.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel structural style of installation pitot tube subassembly, includes the section of intaking, one side outer wall of the section of intaking has the export to take over through the bolt fastening, the hole of the section of intaking is fixed with pitot tube subassembly through lock nut, and pitot tube subassembly's excircle is provided with the parallel key.
Preferably, the inner hole of the leather supporting pipe component and the outer circle of the locking nut are both designed with threads, and the specifications of the two threads are matched.
Preferably, the threads of the pitot tube assembly and the locking nut can be positive threads or negative threads.
Preferably, one end of the locking nut is designed with a cross groove, and the cross groove is of a groove structure.
The utility model has the advantages that:
1. this novel structural style of installation pitot tube subassembly through set up lock nut on the pitot tube, will carry out fixed mounting to the pitot tube through lock nut convenience.
2. This novel structural style of installation pitot tube subassembly through the cross recess of lock nut one end, uses special design's the frock of installing and removing to lock nut locking to reach fixed mounting's effect, through the parallel key, reach the effect that pitot tube subassembly prevented changeing.

fig. 3 is a schematic structural view of the lock nut of the present invention;
fig. 4 is a schematic structural view of the lock nut of the present invention.
In the figure: 1 water inlet section, 2 outlet connecting pipes, 3 pitot tube assemblies, 4 flat keys and 5 locking nuts
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-4, a novel structural style of installation pitot tube subassembly, including the section of intaking 1, the one side outer wall of the section of intaking 1 has the export to take over 2 through the bolt fastening, and the hole of the section of intaking 1 is fixed with pitot tube subassembly 3 through lock nut 5, and pitot tube subassembly 3's excircle is provided with parallel key 4, and 5 one end of lock nut are the external screw thread with 3 hole screw thread phase-matchd of pitot tube subassembly, and one end is the cross recess structure.
The working principle is as follows: when the water inlet pipe is used, the leather supporting pipe component 3 is installed on the water inlet section 1 through a specially-made assembling and disassembling tool, then the leather supporting pipe component is fixed through the locking nut 5 and the flat key 4, and the outlet connecting pipe 2 is fixed on the water inlet section 1 through a bolt after the leather supporting pipe component is locked.
Compare with the taut structure of several screw fixation mode, the utility model discloses no matter it is better in structural optimization still uses the impression, and single lock nut is through special design and special treatment simultaneously, and it has characteristics such as intensity is big, the reliability height.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
