Description
Technical Field
The utility model relates to a mining motor field, a mining motor protection device specifically says so.
Background
The water cooling type is one of the main cooling modes of the mining motor, and the cooling effect is very obvious. However, the coal mine use environment is severe, the situation that water pressure is unstable often exists, the motor base deforms due to overhigh water pressure, use is affected, the motor is difficult to disassemble and maintain, and production efficiency is seriously affected. After the water pressure safety valve is applied, when the water pressure exceeds the preset pressure of the water pressure safety valve, the safety valve automatically releases the pressure, so that the deformation of a motor base is avoided; after the water pressure returns to normal, the water pressure safety valve is automatically closed, and the normal operation of the motor is not influenced. Besides, the water pressure safety valve is made of stainless steel except the sealing ring, so that the phenomenon that the valve core is rusted and blocked can be avoided when the water pressure safety valve works for a long time. The use of the water pressure safety valve can greatly prolong the service life of the mining motor.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a relief valve can adjust water cooling system's pressure, guarantees that pressure is in setting for the within range, and concrete technical scheme is as follows:
a water pressure safety valve for a mining motor is characterized in that a safety valve is arranged on a water cooling system of the mining motor and comprises a spring valve seat, the valve seat comprises a connecting part at the lower part and a valve cavity, a through hole of the connecting part is communicated with the valve cavity, and threads are arranged on the outer side of the connecting part; the valve cavity is cylindrical, a sealing ring is arranged at the bottom of the valve cavity, and the sealing ring surrounds the outer side of the through hole of the connecting part; a sealing washer is arranged above the sealing ring, a spring is arranged above the sealing washer, a washer is arranged above the spring, the washer is provided with a water through hole, the washer is abutted against the valve core, threads are arranged on the outer side of the circumference of the valve core, and the valve core is screwed with a screw hole on the inner side wall of the upper part of the valve cavity; the valve core is provided with a water through port.
In order to prevent impurities in cooling water from flowing into the upper part of the valve cavity and accumulating among the spring bodies of the spring to influence the extension and contraction of the spring, the side wall of the lower part of the valve cavity is provided with a groove, a filter screen is arranged in the groove, a through hole is formed in the middle of the filter screen, and the spring penetrates through the through hole; the outer diameter of the spring is 1-2mm smaller than the diameter of the through hole.
In order to prevent particles in water from being extruded on the sealing gasket and the valve cavity directly to cause the sealing gasket to be incapable of moving, the outer diameter of the sealing gasket is 2-3mm smaller than the inner diameter of the valve cavity to ensure that a gap is reserved between the sealing gasket and the valve cavity.
Preferably, the safety valve is connected with a water-cooling jacket of the motor shell.
The utility model has the advantages that: 1. the problem of deformation of the base of the mining motor caused by overlarge water pressure is effectively avoided, and the service life of the motor is guaranteed. 2. The valve body is small in size, and the installation of the mining motor is not influenced. 3. High reliability, difficult failure and long maintenance period. 3. Simple structure, simple and convenient processing, and is suitable for batch production after being put into production.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention is described in detail below with reference to the accompanying drawings, as shown in the drawings, a safety valve is arranged on a water cooling system of a mining motor, the safety valve includes a spring valve seat 1, the valve seat 1 includes a connecting portion 11 at a lower portion and a valve cavity 12, a through hole 10 of the connecting portion is communicated with an inner space 20 of the valve cavity, and a thread 111 is arranged outside the connecting portion; the valve cavity 12 is cylindrical, the bottom of the valve cavity is provided with a sealing ring 6, and the sealing ring 6 surrounds the outer side of the through hole 10 of the connecting part; a sealing washer 5 is arranged above the sealing ring 6, a spring 4 is arranged above the sealing washer 5, a washer 3 is arranged above the spring 4, the washer 3 is provided with a water through hole 31, the washer 3 is abutted against the valve core 2, the outer side of the circumference of the valve core 2 is provided with threads, and the valve core is screwed with a screw hole on the inner side wall of the upper part of the valve cavity; the valve core is provided with a water through port 8.
In order to prevent impurities in cooling water from flowing into the upper part of the valve cavity and accumulating among the spring bodies of the spring to influence the extension and contraction of the spring, a groove is formed in the side wall of the lower part of the valve cavity, a filter screen 9 is arranged in the groove, a through hole is formed in the middle of the filter screen 9, and the spring 4 penetrates through the through hole; the outer diameter of the spring is 1-2mm smaller than the diameter of the through hole.
In order to prevent particles in water from being extruded on the sealing gasket and the valve cavity directly to cause the sealing gasket to be incapable of moving, the outer diameter of the sealing gasket is 2-3mm smaller than the inner diameter of the valve cavity to ensure that a gap 7 is formed between the sealing gasket and the valve cavity.
Preferably, the safety valve is connected with a water-cooling jacket of the motor shell.
The water pressure safety valve is made of stainless steel except for the sealing ring. The valve port is closed using a valve cartridge, a spring and a sealing gasket. When the water pressure exceeds the preset pressure of the spring, the spring contracts, water flow enters the inner space 20 of the valve cavity from the through hole 10 and then flows out from the water through port 8 of the valve core, and the pressure relief effect is achieved; when the water pressure is smaller than the preset pressure of the spring, the spring rebounds, and the washer is continued to block the through hole 10, so that the pressure setting and protection can be carried out on the water cooling system of the motor according to the setting of the spring.
