Description

Quick connector

Technical Field

The utility model relates to a pipe connection field, more specifically say, relate to a quick-operation joint.

Background

With the development of medium-temperature markets such as solar heating and the like, the demand on a flat plate collector is gradually increased, particularly for a large-scale central heating system, and in order to reduce the maintenance of the system, the flat plate collector is generally adopted as a closed circulation system. When a large-scale flat plate collector operates, the pressure loss of the collector when a pump is started is usually over 1 MPa. When the system has power failure or other faults, the heat collector is overheated to cause closed sunning, and the outlet temperature of the heat collector can reach 200 ℃ and 250 ℃, so that the system has higher requirements on temperature resistance and pressure resistance. Meanwhile, the temperature of the heat collector can reach-30 ℃ or even lower in some areas at night in winter.

The inlet and outlet joints of solar heat collectors in the market are divided into thread sealing, plane sealing and cutting sleeve sealing. When the thread seal is applied at medium and high temperature, high-temperature sealing medium is required, the installation is complex, and the thread seal is generally difficult to disassemble after the installation. The flat gasket seal has high requirement on the verticality of the heat collector and the connector head, and when the heat collector or the connector head is stressed, the heat collector and the connector head are particularly in a cold and hot alternating state, so that the heat collector and the connector head cannot be tightly attached to each other easily to cause leakage. The concentricity requirement of the heat collector tube head is strict due to the sealing of the clamping sleeve, but the tube head is easy to lose roundness in the production and transportation processes of the heat collector, so that the sealing cannot be realized. No matter which kind of seal above adopting, because all can let the heat collector import and export bear the revolving force of screwing up when screwing up, consequently must restrict the rotatory degree of freedom of heat collector import and export, otherwise cause the runner to be twisted and warp easily, this just causes the heat collector structure comparatively complicated.
