[0037] Please refer to Figure 1 to Figure 5 , the present embodiment provides an electromagnetic pilot four-way valve, including: a casing, the casing includes a first casing 11 and a second casing 12, and there is a set angle between the first casing 11 and the second casing 12 included angle; the pilot mechanism 20 is installed in the cavity of the first housing 11; the valve stem assembly is installed in the cavity of the second housing 12, and the second housing 12 has four flow channel holes, and The inner cavity is divided into multiple chambers, and the pilot mechanism 20 is used to drive the valve rod assembly to move in the second housing 12 to change the on-off state between the chambers and the flow channel hole.

[0038]Preferably, the angle between the central axis of the first housing 11 and the central axis of the second housing 12 is 90 degrees. It is set so that the length direction of the first housing 11 is perpendicular to the length direction of the seco...

Abstract

An electromagnetic pilot-operated type four-way valve relates to the technical field of electromagnetic valves and comprises an housing. The housing comprises a first housing body and a second housingbody, and an included angle with a set angle is formed between the first housing body and the second housing body. A pilot mechanism is installed in an inner cavity of the first housing. A valve rodassembly is installed in an inner cavity of the second housing; the second housing is provided with four flow channel holes; the inner cavity of the second housing is divided into a plurality of cavities; and the pilot mechanism is used for driving the valve rod assembly to move in the second housing so as to change the on-off state between the cavities and the flow channel holes. Due to the factthat the included angle is formed between the first housing and the second housing, the electromagnetic pilot-operated type four-way valve is integrally bent, and the length of the electromagnetic pilot-operated type four-way valve is relatively small.

Description

technical field [0001] The invention relates to the field of electromagnetic valves, in particular to an electromagnetic pilot four-way valve. Background technique [0002] At present, solenoid valves include direct-acting solenoid valves, electromagnetic pilot-operated four-way valves and distributed direct-acting solenoid valves. The electromagnetic pilot four-way valve usually includes a pilot valve and a valve body. The opening and closing of the pilot valve is controlled by a magnetic mechanism, thereby controlling the pressure of different chambers in the valve body, so that the valve core in the valve body moves, thereby changing the valve through the valve. body flow direction. [0003] However, due to structural defects of the electromagnetic pilot four-way valve in the prior art, the length of the electromagnetic valve is relatively long. Contents of the invention [0004] The object of the present invention is to provide an electromagnetic pilot type four-way ...
