Embodiment Construction

[0046] take a look first figure 1 The difference between the liquid supply line:

[0047] The electro-hydraulic reversing valve group 1 and the spray water valve group 2 are respectively the parts in the corresponding dot-dash line frame, which is a known technology.

[0048] The high-pressure emulsion P is divided into two liquid paths through the main filter 3 (filter precision 40 μm) and the original three-way joint 16: one joint supplies liquid to the electromagnetic pilot valve 4 of the spray water valve through the high-pressure rubber hose. One way enters the electro-hydraulic reversing valve group 1 through the high-pressure rubber hose, and is divided into two hydraulic circuits in the valve group. One liquid circuit supplies liquid to the main valve 5 of the large-flow electro-hydraulic reversing valve, and the other passes through the damping hole 6 and the damping check valve. 7. After the pilot valve filter 8, it is divided into two liquid circuits, one supplying...

Abstract

The invention provides a spray water valve group and belongs to the technical field of valves. The spray water valve group comprises a spray water valve electromagnetic pilot valve and a spray water valve main control valve. An inlet pipeline is connected with a damping hole, a damping one-way valve and a pilot valve filter through a main filter pipeline, and then is connected with a liquid inlet of the spray water valve electromagnetic pilot valve through a three-way joint in one way, and is connected with an energy accumulator through the three-way joint in another way. The spray water valve electromagnetic pilot valve is correspondingly connected with the spray water valve main control valve. A water inlet of the spray water valve main control valve can be provided with a spray water filter. Emulsion is filtered and stabilized, the electromagnetic pilot valve is not prone to damage, economic benefits and production efficiency are improved, the body health of workers at the underground production line is protected, and occupational diseases are effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a spray water valve group, which can be used for the reconstruction of the spray water valve of the fifth hydraulic support ZY4400 / 06 / 15D (support model) of a coal plow. Background technique [0002] The cooling spray system of the plowing coal face is the guarantee for the normal operation of mechanical equipment, and the quality of the cooling spray system depends on the rationality of the design. The fifth set of plowing hydraulic support ZY4400 / 06 / 15D newly introduced by our group company in recent years has a large number of control failures and leakages. The cost of equipment maintenance will increase, and the poor cooling of mechanical equipment on the working face will affect production. For this reason, it is necessary to modify the spray water valve of the fifth set of coal plow hydraulic support ZY4400 / 06 / 15D. [0003] A better cooling spray system can red...
