Abstract
The utility model relates to a sealing gasket of a heat exchanger, in particular to a double-hanging connection claw sealing gasket of a plate-type heat exchanger, which comprises a gasket main body and a plurality of hanging connection claws arranged on the gasket main body. The hanging connection claws are connected with the gasket main body through two symmetrically-arranged connecting ribs, a concave hole is manufactured on each hanging connection claw, and a locating end is arranged in the concave hole. The double-hanging connection claw sealing gasket is reasonable in structure, accurate in location, capable of guaranteeing using performance of the sealing gasket of the plate-type heat exchanger, achieving repeated use of the sealing gasket and reducing maintenance charge of the plate-type heat exchanger and applicable to detachable plate-type heat exchangers, half welding plate-type heat exchangers and other similar plate-type heat exchangers.
Description
Technical field
The utility model relates to a kind of heat exchanger gasket seal, and a kind of specifically plate type heat exchanger is two to articulate the pawl gasket seal, and it can be applicable on detachable plate type heat exchanger, semi-welded plate heat exchanger and other the similar plate type heat exchanger.
Background technology
Plate type heat exchanger is made up of one group of corrugated metal plate, and is porose on the plate, and two kinds of liquid that supply to conduct heat pass through; Metal sheet is installed in a side to be had in the framework of fixed pressure plate and movable pressure plate, and clamps with fishbolt, and rubber sheet gasketing is housed on the plate; With the fluid passage sealing, and guide cold and hot fluid alternately to flow in the passage separately, quantity and the size that has determined plate with temperature difference falls in the flow of fluid, physical property, pressure; Corrugated plating has not only aggravated turbulent extent; And form many strong points, and be enough to bear the pressure differential between medium, form rectangular channel between each plate; Carrying out heat exchange through plate, is the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange.
Plate adopts the plate type heat exchanger of rubber sheet gasket sealing, and generally speaking, working pressure is no more than 2.5MPa; Serviceability temperature is no more than 160 ℃; The gasket seal of plate type heat exchanger is fixed on has dual mode on the plate, a kind of is gasket seal directly to be sticked in the seal groove of plate with bonding agent, and another kind is to be fixed on the plate through the extension pawl on the gasket seal; This pad also is called as the free bonding pad; Use the free bonding pad, it is rapider that Overhaul of plate heat exchangers is safeguarded, can change pad quickly and easily on the spot.
Present existing free bonding gasket construction is to link to each other with the plate edge through a plurality of pawls that articulate that are provided with on it; Gasket seal is neatly located along the rubber cushion groove on the plate; But there is certain shortcoming and defect in this structure; 1., when gasket seal is connected with plate be in particular in:, articulate pawl and be connected unstablely with the plate edge, pad is prone to scurry the position, departs from seal groove; 2., have a dowel in the middle of the pad, connecting portion is thin, and the phenomenon that dowel ruptures in the production of gasket seal and plate type heat exchanger and maintenance process happens occasionally.The appearance of above-mentioned situation all can make the sealing function decline of pad cause leaking even losing efficacy, and seriously influences the serviceability of plate type heat exchanger, will lose for a long time when the dowel number of breaks and exempt from sticking function.
Summary of the invention
The purpose of the utility model is in order to solve the problem that above-mentioned plate type heat exchanger gasket seal exists; A kind of rational in infrastructure, accurate positioning is provided, can guarantee the plate type heat exchanger gasket seal serviceability, realize the repeatedly utilization of gasket seal, can reduce the two pawl gasket seals that articulate of plate type heat exchanger of the maintenance cost of plate type heat exchanger.
The purpose of the utility model is to realize like this; The sealing pad comprises gasket body, is arranged on a plurality of pawls that articulate on the gasket body; The described pawl that articulates is connected with gasket body through symmetrically arranged two dowels; Articulate and be processed with a concave hole on the pawl, in concave hole, be provided with a positioning end.
The utility model is owing to adopt said structure; Be applied on detachable board-like heat exchanger and the half welded type plate type heat exchanger; Gasket seal can firmly be embedded in the seal groove of plate exactly,, strengthen hanging the bonding strength of pawl and gasket body owing to have two links; Improved the positioning accuracy of pad; Thereby the serviceability that guarantees the plate type heat exchanger gasket seal is normally brought into play, and has satisfied the repeatedly utilization of plate type heat exchanger maintenance work Intermediate gasket, has reduced the maintenance cost of plate type heat exchanger.
The material commonly used of the said pad of the utility model has ethylene propylene diene rubber, acrylonitrile-butadiene rubber, fluorubber and neoprene gasket.
Description of drawings
Fig. 1 is the two pawl gasket seal overall structure sketch mapes that articulate of plate type heat exchanger.
Fig. 2 is that the utility model I place articulates claw portion structure for amplifying sketch map.
Fig. 3 is an A-A cutaway view among the utility model Fig. 2.
The specific embodiment
Shown in accompanying drawing 1: the sealing pad comprises gasket body 1, is arranged on a plurality of pawls 2 that articulate on the gasket body 1.
By accompanying drawing 2, shown in 3: the described pawl 2 that articulates is connected with gasket body 1 through symmetrically arranged two dowels 3, articulates and is processed with a concave hole 4 on the pawl 2, in concave hole 4, is provided with a positioning end 5.
