Preferably, the straight pipe is in a circular ring shape. The straight pipe ring is relatively simple in design, convenient to install and maintain, difficult to accumulate and block due to the straight pipe structure, and beneficial to cleaning and maintenance.
Preferably, a groove is formed in the surface of the nozzle, and the groove is annular. Here, the establishment of the groove can limit the nozzle, so that the nozzle can be fixed inside the straight pipe.
Preferably, the surface of the nozzle is tapered. The design of the conical nozzle can enable fluid to be uniformly distributed in the injection process, so that the non-uniformity and vortex phenomenon during fluid injection are reduced, and the injection stability and consistency are ensured.
Preferably, the appearance of the back locking fixing plate is a trapezoid block, and one end of the back locking fixing plate is fixed with the groove. Here, the setting up of the trapezoidal block can have a function of a limit, so that the nozzle can be fixed.
Preferably, the number of the back locking fixing plates is three, and the spacing distances among the three groups are equal. Here, the setting up of three sets of anti-lock fixed plates can make the nozzle comparatively stable at straight tube internally mounted.
Compared with the prior art, the utility model has the advantages and positive effects that:
1. according to the utility model, through the pipe body fixing ring, the back-locking fixing plate and the groove, the phenomenon that the long-diameter nozzle falls off due to shearing force in the traditional process is avoided, meanwhile, the phenomenon that the welding seam at the pin is leaked due to high pressure is avoided, the problems that the nozzle falls off to cause misalignment of flow or flow speed and influence the accuracy and reliability of measurement are solved, the equipment is damaged due to the falling of the nozzle, the maintenance and repair costs are increased, and the maintenance cost is reduced.

Detailed Description
In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.
Example 1
Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides a long footpath nozzle measuring device, including straight tube 1, straight tube 1 be the ring tubular, straight tube 1 ring tubular design is simple relatively, be convenient for install and maintain, and straight tube 1 structure is difficult for producing and gathers and stop up, be favorable to clean and maintain, the inside fixed mounting of straight tube 1 has body solid fixed ring 3, straight tube 1 inside cover is equipped with nozzle 2, the recess 5 has been seted up on the surface of nozzle 2, recess 5 is the ring shape, the establishment of recess 5 can be spacing to nozzle 2, thereby can fix nozzle 2 inside straight tube 1, the surface of nozzle 2 is the toper, the design of toper nozzle 2 can make fluid evenly distributed in the injection process, unevenness and vortex phenomenon when reducing the fluid injection, guarantee stability and the uniformity of spraying.
Referring to fig. 1-2, one end of the pipe body fixing ring 3 is fixedly provided with a locking fixing plate 4, the appearance of the locking fixing plate 4 is a trapezoid block, one end of the locking fixing plate 4 is fixed with a groove 5, the trapezoid block can have a limiting function, so that the nozzle 2 can be fixed, the number of the locking fixing plates 4 is three, the interval distances among the three groups are equal, the nozzle 2 can be stably installed in the straight pipe 1, and in the utility model, the problem that the nozzle 2 falls off due to shearing force in the traditional process and the problem that the flow or flow speed is inaccurate due to falling of the nozzle 2 and the problem that the accuracy and the reliability of measurement are affected can be avoided by the fact that the welding seam leakage phenomenon at the pin is caused by high pressure is avoided.
