技术领域technical field
本发明涉及一种管道连接件，特别是一种卡扣式管道连接件。The invention relates to a pipeline connector, in particular to a buckle-type pipeline connector.
背景技术Background technique
管道是用管件联接件和阀门等联接成的用于输送气体、液体或带固体颗粒的流体的装置。通常，流体经鼓风机、压缩机、泵和锅炉等增压后，从管道的高压处流向低压处，也可利用流体自身的压力或重力输送。管道的用途很广泛，主要用在给水、排水、供热、供煤气、长距离输送石油和天然气、农业灌溉、水力工程和各种工业装置中。A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipe fittings, valves, etc. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.
然而，在现有技术中，在管道连接时，往往需要焊接或者熔融才能使管道连接在一起，尤其是在家用给排水过程中，通常的管道连接机构都在连接时都需要改变原有管道的形状或者构造，造成在连接时不方便或者需要专业人员才能连接，这就增加了人工成本，且管道连接机构在连接处是最容易发生漏水现象的，当发生漏水现象时只能将整个连接机构更换，这就造成了材料的浪费，同时，更换连接机构也需要专业的技术人员才能更换，使得其使用时繁琐程度增加，不便于使用与推广。为此，现目前出现了一些专用的管道连接件，但是，现有的管道连接件大多采用按压式结构，这种连接方式在安装时，往往会出现抱死状态，以至于给安装和拆卸造成不必要的麻烦，影响安装和拆卸的时间，造成工作人员的工作效率低。However, in the prior art, when the pipes are connected, welding or melting is often required to connect the pipes together, especially in the household water supply and drainage process, the usual pipe connection mechanisms all need to change the shape of the original pipes when connecting. The shape or structure makes it inconvenient to connect or requires professionals to connect, which increases labor costs, and the pipeline connection mechanism is most prone to water leakage at the connection. When water leakage occurs, the entire connection mechanism can only be removed. Replacement, this has just caused the waste of material, meanwhile, the replacement connecting mechanism also needs professional technical personnel just can replace, makes its loaded down with trivial details when using and is not easy to use and popularize. For this reason, some special-purpose pipeline connectors have appeared at present, but most of the existing pipeline connectors adopt a push-type structure. When this connection method is installed, a locked state often occurs, so that it causes damage to the installation and disassembly. Unnecessary trouble affects the time of installation and disassembly, resulting in low work efficiency of the staff.
