Description
Technical Field
The utility model relates to an improve fluid flow characteristic's hose nipple belongs to fluid dynamics technical field.
Background
In the field of existing engineering machinery, few people pay attention to the influence of the flowing characteristic of oil in a hydraulic system on the hydraulic system, the influence of the flowing characteristic of the oil in the hydraulic system on the performance of the hydraulic system is huge in practice, particularly at the joint of a pipeline, the sudden change of the geometric dimension of a flow passage can cause the fluid to generate serious pressure loss, speed fluctuation and other adverse factors, and further the hydraulic system generates the adverse influences of vibration, noise, temperature rise and the like.
The flow problems cover all aspects of life, and play a great role particularly in construction machines, but at the same time the flow problems in the hydraulic system are most easily negligible. When oil flows through a geometric structure with a sudden change in geometric dimension, serious problems of pressure loss, sudden speed change and the like are caused, and the changes can increase the problems of vibration, noise and temperature rise of a hydraulic system and have adverse effects on the hydraulic system.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide a hose nipple who improves fluid flow characteristic.
A hose coupler for improving fluid flow characteristics, comprising:
the end part of the welding pipe joint is provided with a damping hole;
and the joint is in threaded connection with the welded pipe joint, and after the joint is connected with the welded pipe joint, a static high-pressure area is formed at the end part of the joint, and a dynamic low-pressure area is formed at the end part of the welded pipe joint.
Further, the damping holes are annularly distributed along the end part of the welded pipe joint.
Further, the joint and the welded pipe joint are connected by a swivel nut.
Furthermore, an O-shaped sealing ring is arranged at the joint of the joint and the welded pipe joint.
Further, the end of the welded pipe joint is conical.
Furthermore, the end of the joint is provided with a taper groove matched with the end of the welded pipe joint.
Compared with the prior art, the utility model discloses the beneficial effect who reaches: the utility model discloses widely used coupling department among the joint damping aperture mainly used hydraulic system has been set up to improve the flow stability of hydraulic system fluid, reduce fluid loss of pressure and the speed sudden change in coupling department, and then make whole hydraulic system's dynamic behavior more stable, fluid temperature rise range reduces, will have the promotion that is showing to hydraulic system's wholeness ability, the utility model is used for the pipe connection in the hydraulic system in the excavator, but not only be limited to excavator hydraulic system, all fluid flow state's improvement is applicable.

In the figure: 1. a damping hole; 2. rotating the nut; 3. welding a pipe joint; 4. a joint; a. a static high pressure zone; b. a dynamic low-voltage region.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.

A hose coupler for improving fluid flow characteristics, comprising:
the welding pipe joint 3 is characterized in that a damping hole 1 is formed in the end part of the welding pipe joint 3;
a joint 4, wherein the joint 4 is in threaded connection with the welded pipe joint 3, after the joint 4 is connected with the welded pipe joint 3, a static high-pressure area a is formed at the end part of the joint 4, a dynamic low-pressure area b is formed at the end part of the welded pipe joint 3, and the damping holes 1 are annularly distributed along the end part of the welded pipe joint 3; set up the damping aperture of equipartition through welding 3 ports of coupling department, with the static high nip of pipe connection department and developments low-pressure zone intercommunication, the pressure in the static high nip that reduces on the one hand is favorable to the sealed effect of O shape sealing washer, and on the other hand has supplemented the developments low-pressure zone because fluid expansion leads to the not enough shortcoming of fluid, has restrained the shortcoming that low-pressure zone fluid produced the cavitation. The adverse factors such as severe pressure loss and speed fluctuation of fluid caused by the sudden change of the geometric dimension of the flow passage are reduced, and the adverse effects such as vibration, noise, temperature rise and the like of a hydraulic system are reduced due to the increase of the damping small holes. Thereby improving the flow characteristics of the overall hydraulic system.
