Abstract
The invention provides a flexible connection structure of an extra-long rod type liquid level indicator. When the structure is subjected to liquid impact, a straight-rod type liquid level indicator slightly swings, so that the impact force of the liquid is attenuated to lowest, and the liquid level indicator is not damaged. Through the connection structure, one rod type liquid level indicator is divided into multiple sections; the connection structure comprises a bracket, a swinging rod and a gland; the flexible connection structure is in threaded connection with the upper segment of liquid level indicator through the bracket, the flexible connection structure is in threaded connection with the lower segment of liquid level indicator through the gland, and double nuts are used for preventing looseness; the middle part of the bracket is a circular conical surface, the head of the swinging rod matched with the bracket is a spherical surface, when the bracket is subjected to external force, the spherical surface of the swinging rod and the conical surface of the bracket swing, so as to eliminate the liquid impact effect; screw threads are arranged at the internal wall and external wall of the gland, the external screw thread is connected with the liquid level indicator, the internal screw thread is used for connecting and fixing the swinging rod, and double nuts are used for preventing looseness; and the gap between the upper segment of liquid level indicator and the lower segment of liquid level indicator is decided by the length of the swinging rod screwing in the gland.
Description
Technical field
The present invention is mainly used in liquid level measuring technique neck city.
Background technology
The rod-type liquid level meter is exactly a straight-bar with sensing function, and this root straight-bar is inserted in the liquid of liquid level to be measured, and the sensor on the straight-bar just can spread out of the liquid level information of liquid.At present, this rod-type liquid level meter of domestic production generally all short (＜6m), the rod-type sensor that length surpasses 6m is processing difficulties on the one hand, is easy on the other hand flexural deformation under the radial impact of liquid, affects measuring accuracy.
Summary of the invention
For reducing difficulty of processing, avoid the liquid radial impact on the impact of overlength rod-type liquid level meter, the invention provides a kind of flexible connecting structure of overlength rod-type liquid level meter, can be after the impact that is subject to liquid, slight swing occurs in the straight-bar type liquid level meter, it is minimum that the impulsive force of liquid is decayed to, and guarantees that liquid level meter is not damaged.
A kind of flexible connecting structure of overlength rod-type liquid level meter, this syndeton is divided into many sections with a rod-type liquid level meter, described syndeton comprises carriage, fork and gland, carriage is threaded flexible connecting structure with the preceding paragraph liquid level meter, gland is threaded flexible connecting structure with dried one section liquid level meter, all use pairs of anti-loose nut; The carriage middle part is a circular conical surface, and fork head with matching is a sphere, when being subject to external force, swings between the sphere of fork and the conical surface of carriage, eliminates the hydraulic shock effect; Gland inwall and outer wall all have screw thread, and external thread is connected with liquid level meter, and internal thread is used for being connected and fixed fork, adopts equally pairs of anti-loose nut; Gap between epimere liquid level meter and the hypomere liquid level meter, the length that is screwed in gland by fork determines.
The length of each section of rod-type liquid level meter is 3m～4m.
Beneficial effect of the present invention:
1, the present invention is designed to segmental structure with overlength rod-type liquid level meter, adopts flexible connecting structure between segmentation, has reduced the difficulty of processing of single overlength rod-type liquid level meter.
2, flexible connecting structure of the present invention effectively reduces the impulsive force of liquid to the damage of rod member.
3, flexible connecting structure axial rigidity of the present invention is large, and adopts and to be threaded and locking mode, has guaranteed the precision and the intensity that connect.
Description of drawings
Fig. 1 is overlength rod-type liquid level meter work synoptic diagram;
Fig. 2 is flexible connecting structure synoptic diagram among the present invention.
Embodiment
The working position of liquid level meter as shown in Figure 1.The top of container is fixed in the upper end of liquid level meter, and the other end is freely sagging, when liquid when the liquid entrance of container flows into or flows out, respective change can occur in the liquid level in the container, liquid level meter will indicate the situation of change of liquid level by secondary instrument.
Connected by flexible structure between epimere straight-bar type liquid level meter 1 and the hypomere straight-bar type liquid level meter 5, specific constructive form as shown in Figure 2.Carriage 2 middle parts are circular conical surfaces, and fork 3 heads with matching are spheres, when being subject to external force, can swing between the conical surface of the sphere of fork 3 and carriage 2, eliminate the hydraulic shock effect.With being threaded, also with being threaded, and locking with the double nut mode between gland 4 and the fork 3, between gland 4 and next section straight-bar type liquid level meter 5 between the preceding paragraph straight-bar type liquid level meter 1 and the carriage 2.
Dangle in container during liquid level meter work, when the liquid in the container flow to or flows out, liquid can cause radial impact to liquid level meter.After liquid level meter is subject to this power, relative displacement can occur between sphere fork and the carriage, make between each section of liquid level meter small sway occurs, the radial force of liquid effects on liquid level meter decayed to minimum, thereby drop to the infringement that liquid level meter is subject to.
Claims (2)
1. the flexible connecting structure of an overlength rod-type liquid level meter, this syndeton is divided into many sections with a rod-type liquid level meter, it is characterized in that: described syndeton comprises carriage, fork and gland, carriage is threaded flexible connecting structure with the preceding paragraph liquid level meter, gland is threaded flexible connecting structure with next section liquid level meter, all use pairs of anti-loose nut; The carriage middle part is a circular conical surface, and fork head with matching is a sphere, when being subject to external force, swings between the sphere of fork and the conical surface of carriage, eliminates the hydraulic shock effect; Gland inwall and outer wall all have screw thread, and external thread is connected with liquid level meter, and internal thread is used for being connected and fixed fork, adopts equally pairs of anti-loose nut; Gap between epimere liquid level meter and the hypomere liquid level meter, the length that is screwed in gland by fork determines.
2. the flexible connecting structure of a kind of overlength rod-type liquid level meter as claimed in claim 1 is characterized in that, the length of each section of rod-type liquid level meter is 3m～4m.
