Embodiment Construction

[0016] Such as figure 1 , 2 As shown, an integrated two-way throttle valve includes a valve body 1, a sliding valve core 2, an integrated valve core 3, and an integrated valve seat 5. The integrated valve seat 5 and the integrated valve core 3 connect the valve body 1 It is divided into three chambers: the right chamber 11, the valve chamber 12 and the left chamber 13. The integral valve core 3 is provided with a first throttle hole 31, and the sliding valve core 2 is provided with a second throttle hole 21. The valve cavity 12 slides, and the two ends of the valve body 1 can be welded on the pipeline between the evaporator and the condenser of the heat pump air-conditioning system.

[0017] The valve body 1 is provided with positioning grooves 6, 7, and filter screen assemblies 4, 8 are respectively fixed to filter the refrigerant flowing through.

[0018] Such as figure 1 As shown, the conical surface 51 in the one-piece valve seat 5 is made by rolling the pipe wall of th...

Abstract

The invention discloses an integrative bidirectional throttle valve and the production method thereof, which is used for throttling the refrigerant of a heat pump air conditioning system. The integrative bidirectional throttle valve comprising a valve body, a slidable valve core and a filter screen component. The valve body is provided with a left cavity, a right cavity, an integrative valve baseand an integrative valve core. The integrative valve core is provided with a first throttle hole. The slidable valve core which is provided with a second throttle hole is installed in the valve cavity. The periphery of the slidable valve core is provided with arris blocks. The integrative bidirectional throttle valve has simple and reasonable structure, has few moving parts, can save material, and is more reliable to work.

Description

Technical field: [0001] The invention relates to a two-way throttle valve and a manufacturing method thereof, in particular to an integrated two-way throttle valve and a manufacturing method thereof, which are used in heat pump air-conditioning systems. Background technique: [0002] In the heat pump air conditioning system, the throttling component is a key component that determines the performance of the air conditioner. In the heating and cooling cycle, the refrigerant flow rate required by the system is different. In the existing system, most of the capillary throttling elements are used, which are composed of a main capillary, a secondary capillary, a one-way valve, a filter and various connecting parts. Among them, the one-way valve is connected in parallel with the auxiliary capillary, and the flow direction of the refrigerant in the cooling and heating processes is different, so as to realize the control of different flow rates. This throttling structure is connecte...
