Split type thermostatic valve

Abstract

The invention belongs to the field of thermostatic bathrooms, and relates to a thermostatic valve, in particular to a split type thermostatic valve. The split type thermostatic valve comprises a mainvalve body, a shell, a switch valve element and a thermostatic valve element, the main valve body is composed of a left valve body and a right valve body, the switch valve element is arranged in the left valve body, the thermostatic valve element is arranged in the right valve body, a plurality of water flow channels are correspondingly formed in the left valve body and the right valve body, the water flow channels in the left valve body and the corresponding water flow channels in the right valve body are assembled in a butt joint mode and communicate with each other through plug-in components, and at least one group of fastening components used for connecting and fastening the left valve body and the right valve body are further arranged on the main valve body. According to the split type thermostatic valve, two modes of connecting and locking the left valve body and the right valve body are provided, in the first mode, the fastening components are arranged at the positions, outsidethe water flow channels, of the valve bodies, in the second mode, the fastening components are directly arranged on the water flow channels, whether the plug-in structures are double-plug or single-plug structures, the two modes are applicable, and the two locking modes are ingenious in design and can be widely applied to valve bodies of various thermostatic valves.

Description

technical field [0001] The invention belongs to the field of constant temperature sanitary ware, and relates to a constant temperature valve, in particular to a split type constant temperature valve. Background technique [0002] A thermostatic valve is a plumbing device that mixes cold water and hot water and outputs warm water. Its core temperature control mechanism is a thermostatic valve core, which is basically composed of a main body, a temperature sensing element, a return spring, a piston, etc., and automatically adjusts the mixing ratio of cold and hot water through the difference between the outlet temperature of the mixed water and the set temperature, so that the outlet water temperature in a basically constant state. [0003] A common thermostatic valve, also known as a thermostatic faucet, generally includes a casing, a main valve body, a switch spool for controlling water volume and switching, and a thermostatic spool. There are multiple independent water flo...

Problems solved by technology

For example, the Chinese patent with the application number CN201420741028.6 provides a new type of thermostatic faucet, in which a hot water inlet channel, a hot water outlet channel, a mixed water inlet channel and a mixed water outlet channel are opened in the valve body, see its manual and attached drawings It can be seen that the valve body is an integrated configuration, the water channels in the valve body are staggered, the structure is complex and there are many partition walls

In the prior art, when manufacturing this type of valve body, injection molding is often used for integral molding, which often has higher requirements for production technology and manufacturing precision.

However, due to the limitation of the valve body structure, more mandrels will be used, and the longer the water channel, the longer the mandrel required, which reduces the stability of the valve body forming process, and ultimately affects the molding and follow-up of the product. Processing, in actual production, generally has problems such as low production efficiency, low yield rate, and high scrap rate, resulting in waste of resources

Therefore, the existing thermostatic valve structure is difficult to meet the needs of manufacturing
