Abstract
The utility model relates to a sealing gasket structure of a water chamber end cover of a heat exchanger, which comprises a body, wherein the body is a circular thin sheet, is made of rubber and is provided with a plurality of bolt mounting holes along the circumferential direction; the outer edge of the body between the bolt mounting holes is provided with an inward-sunken arc-shaped notch, so that the outer edge of the notch can expand outwards due to compression after the body is mounted through bolts. The utility model relates to a rationally, simple structure, convenient to use can improve the outward appearance of container when guaranteeing the sealing performance between refrigerating plant's hydroecium and tube sheet, moreover, has still saved the many man-hours that the sealed pad of flange face of cutting will consume, has improved economic benefits.
Description
Technical Field
The utility model relates to an air conditioner spare part, especially a sealed pad, specific sealed pad structure of heat exchanger hydroecium end cover that says so.
Background
The end cover of the tube pass water chamber of the shell-and-tube heat exchanger for the air conditioner compresses a sealing gasket between a flange of the end cover of the water chamber and a tube plate by loading a bolt, so that the sealing gasket is deformed, and tiny uneven gaps between metal sealing surfaces are filled, thereby preventing fluid leakage. For the heat exchanger for the air conditioner, the pressure required by the water side is usually 0.4-1.0 MPa, and the pressure is lower, so the structural form of the flanging end socket is mainly selected for the water chamber end cover, and the thickness of the flanging is smaller (about 6-16 mm). To ensure sealing performance, a higher bolt preload load is typically used. However, when the gasket is subjected to a large pressing force, the gasket is subjected to large elastic-plastic deformation, and the edge of the gasket is easily extruded out of the flange surface of the water chamber end cover, so that the appearance of the container is affected. Therefore, improvements are needed to improve the aesthetic appearance of the device.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art's not enough, provide a sealed pad structure of heat exchanger hydroecium end cover, can avoid the sealing gasket to be extruded under guaranteeing sealed prerequisite to, effectively improved refrigerating plant's the pleasing to the eye degree of outward appearance.
The technical scheme of the utility model is that:
a sealing gasket structure of an end cover of a water chamber of a heat exchanger comprises a body, wherein the body is an annular sheet and is made of rubber, and a plurality of bolt mounting holes are formed in the circumferential direction of the body; the outer edge of the body between the bolt mounting holes is provided with an inward-sunken arc-shaped notch, so that the outer edge of the notch can expand outwards due to compression after the body is mounted through bolts.
Further, the outer diameter of the body is equivalent to that of the water chamber end cover flange.
Further, the bolt mounting holes are uniformly formed.
The utility model has the advantages that:
the utility model relates to a rationally, simple structure, convenient to use can improve the outward appearance of container when guaranteeing the sealing performance between refrigerating plant's hydroecium and tube sheet, moreover, has still saved the many man-hours that the sealed pad of flange face of cutting will consume, has improved economic benefits.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
A sealing gasket structure of a water chamber end cover of a heat exchanger comprises a body 1. The body 1 is a circular thin sheet, can be made of rubber, has elasticity, can be lined at the end cover of a water chamber of a heat exchanger of a refrigerating device, and generates certain deformation when being pressed. The outer diameter of the body 1 is equivalent to that of the water chamber end cover flange, and a plurality of bolt mounting holes 2 are uniformly formed in the circumferential direction of the body. The outer edge of the body between the bolt mounting holes 2 is provided with an inward sunken arc-shaped gap 3. The radius of the gap 3 is 180-200mm, and the radial maximum distance between the lowest point of the bottom of the gap and the outer edge 4 of the end cover flange is 3-8 mm, so that the gap 3 can generate elastic-plastic deformation to expand outwards under the pressure of 1MPa of the body 1 and does not exceed the outer edge 4 of the end cover flange, thereby not only ensuring the sealing performance between the water chamber and the pipe plate, but also avoiding the problem that the traditional sealing gasket protrudes out of the end cover flange, and ensuring the appearance of the whole structure to be more beautiful. Meanwhile, the working hours consumed by cutting more flange surface sealing gaskets are saved, and the economic benefit is improved.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
