In the particular surroundings that underground coal mine generates, the coal dust of generation to working face personnel cause the harm probability of silicosis mentions significantly
It is high.Therefore go out dirt, and depositing dust, dust prevention system is just at important a part in coal production.
Spray control valve working principle used at present is as follows:
1. spray valve is in parallel with bracket operation valve, when hydraulic moving stand or the operation of tailstock Sub-Level Caving, emulsion is simultaneously
Push spray valve conducting, depositing dust spray operations.
2. when hydraulic moving stand operation, tailstock Sub-Level Caving, falling frame operation makes hydraulic cylinder pressure lower than 20MPa, or
Hydraulic support occurs from when falling, and spray valve is connected, hydraulic support depositing dust spray operations.
3. carrying out a liter frame at the end of hydraulic moving stand operation or tailstock Sub-Level Caving, when branch bridge joint top, reach setting load
When spray valve close, it is spraying to stop.
4. spray valve is in parallel with bracket operation valve, when hydraulic support rises frame operation, emulsion pushes spray valve to lead simultaneously
Logical, depositing dust stops by spraying.
The spray valve in use, has the following problems:
1. limbers is small, water route is easily blocked when water quality inferiority by spraying, and rust is dead afterwards for a period of time for equipment out of use, and control valve is scrapped.
It is spraying to stop 2. there is liter frame to act during moving frame and Sub-Level Caving, therefore spray process is discontinuous.
3. cutting sealing circle when spool acts causes to alter liquid and run, drip, leak, leap up liquid problem.
Summary of the invention
The utility model does not work for existing spray control valve in shifting frame and Sub-Level Caving process, metals run out, leakage,
Liquid is altered, the problem of stopping working by spraying, provides a kind of spray control valve of dust-proof dust suppression system.
The utility model adopts the following technical solution:
A kind of spray control valve of dust-proof dust suppression system, including connector I, spool, spring, connector II and connector III, connect
First I one end is equipped with the interface I connecting with the liter frame oil cylinder of hydraulic support, and the other end is equipped with the oil inlet penetrated through with interface I, into
The connection of one end of hydraulic fluid port and spool, one end of connector II are equipped with the interface II connecting with spraying water source, and the other end is equipped with and interface
One end of connector III is protruded into the water inlet of II perforation, one end that connector I is equipped with oil inlet, and one end that connector II is equipped with water inlet is stretched
Enter the other end of connector III, spool is located in the space that connector I, connector II and connector III form, spring wrap on spool,
Spool is greater than the aperture of water inlet close to the diameter of one end of water inlet, and the bottom of connector III is equipped with water outlet, and water outlet is located at
The space bottom that connector I, connector II and connector III form.
One end that the spool is connect with oil inlet is equipped with boss I, and boss I is embedded in oil inlet.
One end that the spool is located at the close oil inlet in the space that connector I, connector II and connector III form is equipped with
Boss II, the width of boss II are greater than the aperture of oil inlet.
One end of the spring is connect with connector II close to one end of water inlet, and the other end is connect with boss II.
The beneficial effects of the utility model are as follows:
1. the utility model is mounted on the hydraulic control system of hydraulic support, in water supply pipe, when operation bracket accordingly moves
When making, it is automatically opened or closed spraying water route using the high-pressure emulsion (working solution) of pipeline, starts fully mechanized mining, fully mechanized coal face branch
Frame moves frame, drops frame, auto spraying depositing dust during Sub-Level Caving, and spray effect can obtain depositing dust requirement.
2. setting prop emulsion pressure reduction, spraying system can be automatic when hydraulic support occurs from frame, tail boom is fallen from when falling
Starting, therefore, the utility model fall frame, tail boom certainly to hydraulic support and fall certainly with Realtime Alerts effect.
3. the utility model long service life, structure is simple, easy to operate, and failure rate is low.
4. the utility model spraying energy normal use between frame, obtains atomizing de-dusting effect conscientiously, is Coal Miners
Physical and mental health play great role.
