Description

Pressure detecting composite sleeve compensator

Technical Field

The utility model relates to a pipeline equipment technical field, concretely relates to examine compound sleeve compensator of pressure.

Background

The sleeve compensator is used as a compensation device of a hot fluid pipeline, is suitable for media such as hot water, steam, grease and the like, and achieves compensation of thermal expansion through sliding movement of the core pipe relative to the reducer pipe or the outer shell. Most of the existing sleeve compensators are provided with an inner pipe sleeved variable-diameter pipe structure, a medium pressure balance structure is lacked, and when corresponding acting force is generated due to temperature change, the inner pipe can perform good compensation response; when a large medium pressure exists in the inner pipe, the pressure in the pipeline is easy to fluctuate due to lack of medium pressure balance compensation, so that the sleeve compensator needs to be detected in real time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a examine compound sleeve compensator of pressure.

The technical scheme of the utility model is that: the utility model provides a examine compound sleeve compensator of pressure, including the core pipe subassembly, the reducing pipe in core pipe subassembly outer lane is established to the cover, the left end of reducing pipe passes through the crown plate and is connected with the outer wall of core pipe subassembly, be equipped with seal structure between the left end inner wall of reducing pipe and the tip of core pipe subassembly, two O type sealing washers have been arranged in proper order along core pipe subassembly toward reducing pipe direction to seal structure, a Y type sealing washer, be equipped with the through-hole between two O type sealing washers, the through-hole is connected to the pressure measurement table that sets up outside the core pipe subassembly through setting up the leak hunting pipe in the core pipe subassembly.

According to a further technical scheme, the O-shaped sealing ring is a water-swelling sealing ring.

According to a further technical scheme, the Y-shaped sealing ring is a rubber sealing ring.

The utility model has the advantages that:

the utility model discloses an increased triple seal structure in sealing mechanism department, be equipped with the leak hunting pipe that is connected to the pressure detection table between two O type sealing washers, but through setting up the pressure change of the pressure detection table monitoring seal structure department outside the core pipe subassembly to can in time react revealing.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The device comprises a core pipe assembly 1, a reducer pipe 2, a ring plate 3, a sealing structure 4, an O-shaped sealing ring 5, a Y-shaped sealing ring 6, a leakage detecting pipe 7 and a pressure detecting meter 8.

Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in fig. 1, the utility model provides a pressure detecting composite sleeve compensator, this composite sleeve compensator includes core pipe assembly 1, the cover is established at reducing pipe 2 of core pipe assembly 1 outer lane, reducing pipe 2's left end is connected with core pipe assembly 1's outer wall through crown plate 3, be equipped with seal structure 4 between reducing pipe 2's left end inner wall and the tip of core pipe assembly 1, seal structure 4 has arranged two O type sealing washers 5, a Y type sealing washer 6 along core pipe assembly 1 toward reducing pipe 2 direction in proper order, two O type sealing washers 5, a Y type sealing washer 6 forms triple seal structure 4, wherein, O type sealing washer 5 is the water-swelling sealing washer, Y type sealing washer 6 is rubber seal;

a through hole is arranged between the two O-shaped sealing rings 5 and is connected to a pressure detection meter 8 arranged outside the core tube assembly 1 through a leakage detection tube 7 arranged in the core tube assembly 1.

The pressure change at the sealing structure 4 can be monitored by the pressure detecting gauge 8 provided outside the core tube assembly 1, so that the leakage can be responded to in time.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
