Abstract
The utility model belongs to means for protecting power device when water-break technical field, discloses mining means for protecting power device when water-break.Its technical characteristics is: comprise equipment outlet pipe, described equipment outlet pipe has outlet, and outlet port is provided with valve body, and the piston that valve body is stretched on top is provided with seal ring and spring, the tail end of piston is connected with two position three-way valve, and two position three-way valve is provided with suction tude and gas source pipe.Mining means for protecting power device when water-break provided by the utility model, when the anhydrous discharge of equipment outlet pipe, outlet port is without pressure; piston resets under the action of the spring; two position three-way valve resets under the effect of reset itself spring simultaneously, and cut off source of the gas, pneumatic equipment quits work.Play after cutting off the water supply, to the protection of pneumatic equipment, improve the working life of pneumatic equipment.Also be the saving to source of the gas simultaneously.This device controls source of the gas by mechanical type, than automatically controlled safety and reliability.
Description
Technical field
The utility model belongs to means for protecting power device when water-break technical field, particularly relates to a kind of mining means for protecting power device when water-break.
Background technique
The pneumatic equipment such as various water pumps, diaphragm pump, submersible pump used at each mine is at present in running; complete when the work of drawing water or break down because of water intake, pipeline and cut off the water supply; if now shut down not in time, the damage of equipment and the waste of resource may be caused.The automatically controlled mode of current employing carries out water cut-off protection to above equipment, but for the equipment used under mine, adopting automatically controlled is not still a kind of desirable device.
Model utility content
The technical problems to be solved in the utility model is just to provide a kind of mechanical mining means for protecting power device when water-break of safety and reliability.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise equipment outlet pipe, described equipment outlet pipe has outlet, outlet port is provided with valve body, the piston that valve body is stretched on top is provided with seal ring and spring, the tail end of piston is connected with two position three-way valve, and two position three-way valve is provided with suction tude and gas source pipe.
When mining means for protecting power device when water-break provided by the utility model is installed; in the outlet port of equipment outlet pipe by be provided with piston, seal ring, spring valve body install; the tail end of piston is connected with two position three-way valve; the gas source pipe of two position three-way valve connects source of the gas, and the suction port of the pneumatic equipments such as suction tude and water pump, diaphragm pump, submersible pump is connected.During work, because two position three-way valve is normally close valve, need first two position three-way valve to be opened, make source of the gas by pneumatic equipment air feed such as gas source pipe, suction tude feed water pump, diaphragm pump, submersible pumps, now the pneumatic equipment such as water pump, diaphragm pump, submersible pump is started working, by the draining of equipment outlet pipe, the outlet of equipment outlet pipe has pressure, Compress Spring, promotion piston moves right, thus continue to open two position three-way valve, source of the gas is communicated, the pneumatic equipment continuous firings such as water pump, diaphragm pump, submersible pump with pneumatic equipments such as water pump, diaphragm pump, submersible pumps.Complete when drainage works or break down because of water intake, pipeline, during the anhydrous discharge of equipment outlet pipe, outlet port is without pressure, piston resets under the action of the spring, two position three-way valve resets under the effect of reset itself spring simultaneously, cut off source of the gas, the pneumatic equipments such as water pump, diaphragm pump, submersible pump quit work.So just play after cutting off the water supply, to the protection of the pneumatic equipments such as water pump, diaphragm pump, submersible pump, improve the working life of the pneumatic equipments such as water pump, diaphragm pump, submersible pump.Also be the saving to source of the gas simultaneously.When again working, reopening two position three-way valve, starting again the work of a new round.Mining means for protecting power device when water-break provided by the utility model controls source of the gas by mechanical type, than automatically controlled safety and reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mining means for protecting power device when water-break of the utility model.
Embodiment
Be described in further details below in conjunction with the concrete structure of accompanying drawing to the mining means for protecting power device when water-break of the utility model.
As shown in Figure 1; mining means for protecting power device when water-break provided by the utility model comprises equipment outlet pipe 1; equipment outlet pipe 1 has outlet 2; export 2 places and be provided with valve body 3; the piston 4 that valve body 3 is stretched on top is provided with seal ring 5 and spring 6; the tail end of piston 4 is connected with two position three-way valve 7, and two position three-way valve 7 is provided with suction tude 8 and gas source pipe 9.
When mining means for protecting power device when water-break provided by the utility model is installed; at outlet 2 place of equipment outlet pipe 1 by be provided with piston 4, seal ring 5, spring 6 valve body 3 install; the tail end of piston 4 is connected with two position three-way valve 7; the gas source pipe 9 of two position three-way valve 7 connects source of the gas, and suction tude 8 is connected with the suction port of the pneumatic equipments such as water pump, diaphragm pump, submersible pump.During work, because two position three-way valve 7 is normally close valve, need first two position three-way valve 7 to be opened, make source of the gas by gas source pipe 9, suction tude 8 feed water pump, diaphragm pump, the pneumatic equipment air feed such as submersible pump, now water pump, diaphragm pump, the pneumatic equipments such as submersible pump are started working, by equipment outlet pipe 1 draining, the outlet 2 of equipment outlet pipe 1 has pressure, Compress Spring 6, promote piston 4 to move right, thus continue to open two position three-way valve 7, make source of the gas and water pump, diaphragm pump, the pneumatic equipments such as submersible pump communicate, water pump, diaphragm pump, the pneumatic equipment continuous firings such as submersible pump.Complete when drainage works or break down because of water intake, pipeline, during the anhydrous discharge of equipment outlet pipe 1, export 2 places without pressure, piston 4 resets under the effect of spring 6, two position three-way valve 7 resets under the effect of reset itself spring simultaneously, cut off source of the gas, the pneumatic equipments such as water pump, diaphragm pump, submersible pump quit work.So just play after cutting off the water supply, to the protection of the pneumatic equipments such as water pump, diaphragm pump, submersible pump, improve the working life of the pneumatic equipments such as water pump, diaphragm pump, submersible pump.Also be the saving to source of the gas simultaneously.When again working, reopening two position three-way valve 7, starting again the work of a new round.
The utility model is not limited only to above-mentioned form, but no matter is adopt which kind of structure, as long as identical with mining means for protecting power device when water-break structure provided by the utility model, all falls into protection domain of the present utility model.
