Detailed Description
As shown in fig. 1 and 2, the pressure balance type double-control water spray valve comprises a valve body 1 provided with a valve core assembly, wherein a valve cavity of the valve core assembly is communicated with a liquid inlet A and a water spray opening B. Specifically, the valve core assembly is connected with the valve seat 3 through the valve sleeve 2 in a screwed mode to form a whole, the valve sleeve 2 is only required to be screwed on the valve body 1 during installation, sealing rings are installed on the outer peripheral surfaces of the valve sleeve 2 and the valve seat 3 to seal, the valve core assembly is convenient to integrally insert and install, the installation and disassembly processes are simplified, and the maintenance is convenient and quick. The outside of the valve sleeve 2 and the valve seat 3 are respectively provided with a closing control port P b And a start control port P k An axially sliding valve rod 4 is arranged in a mounting hole which is communicated with the inner side of the valve sleeve 2 and the inner side of the valve seat 3 in an opposite way; the two ends of the valve rod 4 are respectively provided with a radial seal, a closing cavity C and a starting cavity D which are correspondingly formed with the valve sleeve 2 and the valve seat 3, and the closing cavity C and a closing control port P b A starting cavity D and a starting control port P k Respectively pass through the resistorsThe nylon holes are communicated; in the guide bracket 5 that sets up on valve holder 3 was worn to locate at valve rod 4 middle part, install sealed 6 on the guide bracket 5, when sealed 6 and valve rod 4 are gone up and are close to the annular platform sealing fit that valve pocket 2 one side set up (see fig. 1), the valve pocket is divided into the import that is located sealed face left side and is held liquid chamber E and is located sealed face right side and hold liquid chamber F, and above-mentioned import holds liquid chamber E is linked together with inlet A through seting up radial hole on valve pocket 2, and export holds liquid chamber F and is linked together with water jet B through seting up radial hole on valve holder 3. In order to prevent the valve port from being opened by misoperation and enable the valve to be opened out of control, a sealing piston 7 is arranged in a mounting groove formed in one end, close to the valve sleeve 2, of the valve rod 4, one side of the sealing piston 7 is a closing cavity C, the other side of the sealing piston 7 is a balancing cavity G, and the balancing cavity G is communicated with an outlet liquid storage cavity F through a flow channel formed in the valve rod 4.
The invention generally uses water as a working medium and is used for a spraying system of a mining hydraulic support. After the liquid inlet A is connected with a system water supply pipeline, the liquid inlet pressure generates rightward thrust to the annular table on the pressure valve rod 4, the annular table of the valve rod 4 is tightly pressed on the sealing pad 6 of the guide bracket 5, the right side of the annular table and the left end face of the sealing pad 6 form a sealing surface, the inlet liquid storage cavity E and the outlet liquid storage cavity F are separated, and the liquid inlet of the water spray valve is in a closed state.
When water (mist) spraying is needed, the control port P is started k The liquid inlet and pressure liquid enters the starting cavity D through the damping hole, leftward thrust is generated on the valve rod 4, the valve rod 4 is pushed to move leftwards, the sealing surface of the annular table and the sealing gasket 6 are separated, the inlet liquid storage cavity E is communicated with the outlet liquid storage cavity F, the valve port is opened, and liquid enters the water spraying port B from the liquid inlet A through the valve cavity to perform water spraying (mist) operation.
When the water (mist) needs to be sprayed, the control port P is closed b The liquid is fed into the closing cavity C through the damping hole, the pressure liquid generates rightward thrust to the valve rod 4, the valve rod 4 is pushed to move rightward until the annular table and the sealing gasket 6 form sealing, the inlet liquid storage cavity E and the outlet liquid storage cavity F are separated, the valve port is closed, the liquid inlet A and the water spraying port B are blocked, and the spraying system is closed to stop water spraying (mist) operation.
During the process of closing the water spray (fog), when the valve port is closedWhen the valve is closed, the high-pressure liquid in the outlet liquid storage cavity F and the water jet B is not discharged, and certain residual pressure is generated. At the shut-down control port P b After stopping the feed liquor, the residual pressure of export holds liquid chamber F department and acts on valve rod 4, can lead to valve rod 4 left motion and make the valve mouth malfunction open, and the spray valve is out of control and is opened, causes the work disorder of spray valve and spraying system malfunction, influences the job stabilization and the reliability of double control spray valve. For this purpose, the invention provides a sealing piston 7 inside the valve rod 4, which sealing piston 7 can axially balance the residual pressure inside the valve rod 4. Specifically, the high-pressure liquid remained in the outlet liquid storage cavity F and the water spraying port B enters the balance cavity G through the flow channel on the valve rod 4, the liquid pressure acts on the sealing piston 7 to push the sealing piston 7 to move leftwards until the sealing piston contacts with the end face of the valve sleeve 2, and the influence of the residual pressure on the valve rod 4 is counteracted through the balance action of the sealing piston 7, so that the valve port can be reliably closed, and the misoperation of the water spraying valve and the disturbance of the working performance are effectively prevented.
