Embodiment Construction

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0045]It should be noted that when an element is referred to as being “disposed on” another element, it may be directly disposed on the other element or there may be an intervening element. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "affixed to" another element, it can be d...

Abstract

The invention relates to a bidirectional throttle valve. The bidirectional throttle valve comprises a valve pipe, a communicating piece, a first valve element assembly and a second valve element assembly. The communicating piece is arranged in the valve pipe and divides the interior of the valve pipe into a first valve cavity and a second valve cavity. The communicating piece is provided with a first cavity, a second cavity, a first channel and a second channel, the first cavity is located in the end, close to the first valve cavity, of the communicating piece, the second cavity is located inthe end, close to the second valve cavity, of the communicating piece, the first channel communicates with the first cavity and the second valve cavity, and the second channel communicates with the second cavity and the first valve cavity. The first valve element assembly is arranged at the first cavity. The second valve element assembly is arranged at the second cavity. The first channel and thesecond channel are both arranged to be linear channels inclined relative to the axial direction of the communicating piece. According to the bidirectional throttle valve, the number of parts is small,the structure is simple, the installation process is very simple, and therefore the production cost of the bidirectional throttle valve is greatly reduced. When fluid flows in the first channel and the second channel, the flow resistance is small, and therefore the stability of the bidirectional throttle valve is better.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a two-way throttle valve. Background technique [0002] Throttle valves are mainly used in air conditioning and refrigeration systems and are an important part of the refrigeration system. The two-way throttle valve is mainly used in heating and cooling air-conditioning systems, and two throttle valve components are connected in parallel or in series to realize the two-way flow function. [0003] The existing two-way throttle valve has many components, the assembly process is complicated, and the production cost is high. Contents of the invention [0004] In view of this, it is necessary to provide a two-way throttling valve, which can simplify the structure, simplify the assembly process, and reduce the cost. [0005] The invention provides a two-way throttle valve, comprising: [0006] valve tube; [0007] A connecting piece, which is arranged in the valve pipe and divides...
