Abstract
The invention provides an L-shaped three-way reversing stop valve and a machining method, and relates to the technical field of valve manufacturing. The L-shaped three-way reversing stop valve comprises a valve element and a valve body. A through flow cavity is formed in the valve element, a mounting hole, a first shunting hole, a second shunting hole and a third shunting hole are formed in the valve body, and the first shunting hole, the second shunting hole and the third shunting hole communicate with the mounting hole. The valve element can be rotationally arranged in the mounting hole, thevalve element rotates relative to the valve body, fluid is reversed and stopped, the structure is reliable, use is flexible, the operation is convenient, meanwhile, the machining method is simple, and assembly and overhauls are easily achieved.
Description
technical field [0001] The invention relates to the technical field of valve body manufacturing, in particular to an L-shaped three-way reversing cut-off valve and a processing method. Background technique [0002] The three-way valve has three inlets and outlets. The most obvious difference in appearance between the three-way valve and the two-way valve is that there is one more flow port. The three-way valve is mainly used to change the flow direction of the medium, which usually includes three flow ports of inlet, outlet and reversing port. The two-way valve does not have the function of changing the flow direction of the medium. [0003] The current L-shaped three-way valve mainly has a spool as a spool, and the process of processing and assembling the matching valve body is relatively complicated, and the maintenance is inconvenient and the manufacturing cost is high. Contents of the invention [0004] The purpose of the present invention includes, for example, to pr...
