| description | The invention discloses a spray nozzle mounting pedestal in drum shearer. The spray nozzle mounting pedestal comprises a shell and a valve core, the shell is composed of a water inlet hole, a water outlet hole, a left sidewall, a right sidewall and a circular tube wall, the valve core is composed of a sealing cone, a spring, a sealing circular plate, sealing rings and a thimble, the port of the water inlet hole connected with the left sidewall and the port of the water outlet hole connected with the right sidewall are respectively provided with a sealing ring, the left sidewall and the right sidewall are respectively arranged at the left port and the right port of the circular tube wall, the spring is positioned in the circular tube wall, and is in a compressed state, one end of the spring is connected with the sealing cone, the other end of the spring is connected with the sealing circular plate, the other surface of the sealing circular plate is provided with the thimble, the cone mouth of the sealing cone is pushed into the water inlet hole under the spring action of the spring, and the sealing circular plate clings to the right sidewall. Water flow can pass through the pedestal and enter a nozzle during normal work; when the nozzle sheds, the sealing circular plate closes the water outlet hole to prevent water flow short circuit; and when the water pressure is too low or water supply is cut off, the sealing cone closes the water inlet hole to prevent intrusion of coal rock chips into a water supply system. |
