Embodiment 1

[0021] Such as image 3 , 4 The electromagnetic four-way valve shown includes the same main valve 1, pilot valve 2 and coil 3 as those in the prior art. The upper side of the main valve body 11 is connected with a normally open pipe D extending upward. The main valve body 11 The lower side is connected with the middle connecting pipe S extending downward and two side connecting pipes E / C juxtaposed with the middle taking place;

[0022] also,

[0023] The normally open connecting pipe D deviates from the center position of the main valve body 11 and is located on the left side, so that a large space is left on the right side to install the pilot valve 2 through the bracket assembly 4 and install the coil 3 on the pilot valve 2. The position takeover S is located at the center of the main valve body 11, and the two side takeovers E / C are located on both sides of the middle takeover S;

[0024] The bracket assembly 4 includes two brackets 41 and a card 42 fixed (such as welde...

Embodiment 2

[0027] According to the first embodiment, on the premise that the size of the entire electromagnetic four-way valve in the left and right direction can not be increased, the normally open connecting pipe is located at the center of the main valve body.

Embodiment 3

[0029] According to the specific situation, the central connecting pipe in the first embodiment is arranged off the center line, and then the two side connecting pipes are respectively arranged side by side on both sides of the central connecting pipe.

[0030] The structural changes of the above-mentioned several embodiments do not affect the working principle of the electromagnetic four-way valve, so the working principle will not be repeated here.

Abstract

A solenoid operated four-way valve belongs to air conditioning accessories. The prior solenoid operated four-way valve has the shortcoming of larger volume. The solenoid operated four-way valve comprises a main valve, a pilot valve and a coil, wherein, a normal open pipe is connected to the upper side of the valve body of the main valve and extends upwards; a neutral position pipe and two lateral position pipes are connected to the lower side of the valve body of the main valve and extend downwards; and the two lateral position pipes and the neutral position pipe are arranged side by side. The solenoid operated four-way valve is characterized in that the pilot valve is positioned on the upper side of the valve body of the main valve at the side of the normal open pipe; and the coil is connected to the pilot valve. In the solenoid operated four-way valve, the pilot valve and the coil are arranged on the upper side of the valve body of the main valve, thereby reducing the dimensions of the whole solenoid operated four-way valve in the front and the back directions, having compact and beautiful structure, reducing the volume of the valve, and reducing the occupied space of assembly, so that the solenoid operated four-way valve can be installed when in use.

Description

technical field [0001] The invention relates to an electromagnetic four-way valve used for a heat pump air conditioner, belonging to an air conditioner system accessory. Background technique [0002] Electromagnetic four-way valve is a product used in heat pump air conditioners to change the flow direction of cooling system to realize the conversion between cooling mode and heating mode. Such as figure 1 , 2 As shown, it is mainly composed of electromagnetic coil 3, pilot valve 2 and main valve 1. The electromagnetic coil 3 is installed on the pilot valve 2, and the reversing of the pilot valve is realized through the energization and de-energization of the electromagnetic coil, the reversing of the main valve is realized through the reversing of the pilot valve, and the switching of the pipeline through the main valve, Realize the change of the refrigerant flow, so that the air conditioner can achieve the purpose of cooling in summer and heating in winter. [0003] The ...
