Abstract
The invention discloses a spherical stop valve for an underground combined mining working surface of a coal mine. The spherical stop valve comprises a valve body assembly, a spherical valve core and a rotating mechanism, wherein a hydraulic channel is arranged in the valve body assembly; the spherical valve core is arranged in the valve body assembly; the spherical valve core is connected with the rotating mechanism; a sealing base is arranged between the valve body assembly and the spherical valve core; the hydraulic channel is divided into a liquid inlet channel and a liquid outlet channel; the liquid inlet channel is located on the front face of the spherical valve core; the liquid outlet channel is located on the back face of the spherical valve core; a branch channel is arranged between the liquid inlet channel and the liquid outlet channel; and a pilot valve is arranged on the branch channel. The spherical stop valve disclosed by the invention has the advantages as follows: the pilot valve is opened at first, so that an oil pressure medium in the liquid inlet channel flows from the branch channel to the liquid outlet channel until an oil pressure in the liquid inlet channel is essentially equal to an oil pressure in the liquid outlet channel; and then a handle is rotated to open the spherical stop valve, so that the oil pressure medium can smoothly flow through the stop valve. Compared with the traditional stop valve, the spherical stop valve has the advantages that the handle is wrenched in a more labor-saving manner.

Described valve component comprises body, joint and connection block; Described joint is fixed on the front end of body, and described connection block is fixed on the rear end of body, and described feed pathway is first through hole in the joint; Described liquid outlet channel is second through hole in the connection block; Be provided with third through-hole in the described spherical valve core, described first seal ring is arranged on the rear end of joint, and described second seal ring is arranged on the front end of connection block.
Described rotating mechanism comprises valve rod and handle, and described valve rod is connected with spherical valve core, and described handle and valve rod are fixed.
Be fixed with spacing shim on the described valve rod, described body is provided with round pin, and described spacing shim and described round pin cooperatively interact.Spacing shim and round pin cooperatively interact, and play the amplitude that the adjustment handle rotates.
Described bypass passage comprises the L shaped passage that is arranged on the body; Described pilot valve comprises that block, guide's handle and head have the piston rod of the conical surface; Block passes through screw on body; Piston rod passes described block, and described guide's handle is fixed on the afterbody of piston rod, and the head of described piston rod can stretch into the corner of L shaped passage.Through the advancing or retreat of piston mandarin orange, reach the purpose that bypass passage is closed or opened.
Described joint front end is stamped plastic cap, and it is stifled that described connection block rear end is provided with plastics.Prevent that dust or aqueous vapor from entering into the inside of stop valve, avoid stopping up or getting rusty.
Described first seal ring is identical with the structure of second seal ring; The outside of described first seal ring is the plane; The inboard of described first seal ring is the conical surface, fits in the rear end of described plane and joint, and the described conical surface contacts with the outer surface of described spherical valve core.The setting of the conical surface can make spherical valve core under pressured state, separate with first seal ring, forms the slit.If the inboard of seal ring is a sphere, seal ring and sphere are fitted fully, can't form the slit because of resistance can make spherical valve core can't rotate perhaps.
Compared with prior art, the invention has the advantages that working as spherical stop valve is under the closed condition, the spherical valve core both sides that are positioned at hydraulic channel exist under the situation of big pressure difference; Usually pressure difference is 35.1MP; Spherical valve core pressurized in the spherical stop valve is very big, opens pilot valve earlier, makes the oil pressure medium in the feed pathway flow to liquid outlet channel from bypass passage; Make oil pressure and the oil pressure in the liquid outlet channel in the feed pathway basic identical; This moment is handle with sleeve again, and spherical stop valve is opened, and makes the oil pressure medium can flow through stop valve smoothly.Compare traditional stop valve, it is more laborsaving to pull handle.
