Description
Technical Field
The utility model relates to a cylinder headstock gear specifically is a cylinder starting valve.
Background
The starting valve is an important part on the air cylinder, the opening and the closing of the starting valve are realized by compressing air inside the starting valve to generate a pressure difference inside the starting valve, and the air pressure inside the starting valve is controlled by an air distributor. The existing pneumatic valve is usually composed of a valve seat, a valve plate, a spring, a bolt and the like, the valve plate controls the starting valve to be opened and closed, the valve plate is easy to deform or damage under the action of gas pressure, the starting and closing are untimely, frequent maintenance and replacement are needed, time and labor are wasted, and the service life of the starting valve is also shortened.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple structure, long service life starts the timely cylinder starting valve with the closure.
Cylinder start-up valve, including the valve body of tube-shape, the middle part of valve body is provided with the ladder boss, has set gradually spring leaf and packing ring on the ladder boss, the one end fixedly connected with valve rod seat of valve body, the piston that the other end setting can remove in the valve body, valve rod seat and piston are passed in proper order to the inside valve rod that sets up of valve body, the tip and the piston of valve rod pass through self-locking nut fixed connection, and valve rod seat relative slip can be followed to the valve rod, and the one end that valve rod and valve rod seat are connected is sealed for the conical surface laminating of conical surface and valve rod seat, still be provided with the rectangle spring between piston and the packing ring, the both ends of rectangle spring offset with packing ring and piston respectively, and the lateral wall that the valve body is close to valve rod seat one end is provided with the air vent that the compressed air that supplies air distributor to pass through.
The air cylinder starts the valve, compressed air enters the valve body through the air vent via the air distributor, the spring is compressed under the action of pressure and drives the piston and the valve rod to move leftwards, the conical surface of the valve rod is separated from the conical surface of the valve rod seat, the valve is opened, and the compressed air enters the air cylinder from the valve. After the cylinder is filled with compressed air, the air distributor is reversed, no compressed air is filled in the valve body, the piston and the valve rod move towards the right under the action of the spring, so that the conical surface of the valve rod is attached to the conical surface of the valve rod seat again, and the valve is closed. The spring piece and the gasket arranged in the middle of the valve body can play a role of buffering when the spring is compressed or rebounded, so that the overall working stability is improved, and the service life is prolonged. The utility model discloses simple structure, job stabilization can in time open and close the cylinder, improves the job stabilization nature of cylinder.

Detailed Description
As shown in fig. 1, an air cylinder starting valve comprises a cylindrical valve body 3, wherein a stepped boss is arranged in the middle of the valve body, a spring piece 4 and a gasket 9 are sequentially arranged on the stepped boss, one end of the valve body is fixedly connected with a valve rod seat 1, the other end of the valve body is provided with a piston 7 capable of moving in the valve body, a valve rod 2 is arranged in the valve body and sequentially penetrates through the valve rod seat 1 and the piston 7, the end part of the valve rod is fixedly connected with the piston through a self-locking nut 8, the valve rod can slide along the valve rod seat relatively, one end, connected with the valve rod seat, of the valve rod is in a conical surface fit sealing with the conical surface of the valve rod seat, a rectangular spring 5 is further arranged between the piston and the gasket, two ends of the rectangular spring respectively abut against the gasket and the piston, and a. The air cylinder starts the valve, compressed air enters the valve body through the air vent via the air distributor, the spring is compressed and drives the piston and the valve rod to move leftwards, the conical surface of the valve rod is separated from the conical surface of the valve rod seat, the valve is opened, and the compressed air enters the air cylinder from the valve. After the cylinder is filled with compressed air, the air distributor is reversed, no compressed air is filled in the valve body, the piston and the valve rod move towards the right under the action of the spring, so that the conical surface of the valve rod is attached to the conical surface of the valve rod seat again, and the valve is closed. The spring piece and the gasket arranged in the middle of the valve body can play a role of buffering when the spring is compressed or rebounded, so that the overall working stability is improved, and the service life is prolonged. The utility model discloses simple structure, job stabilization can in time open and close the cylinder, improves the job stabilization nature of cylinder.
The cylinder starting valve, the piston is also sleeved with a piston ring 6 to improve the air tightness between the piston and the valve body.
According to the cylinder starting valve, the side wall of one end, close to the valve rod seat, of the valve body is evenly provided with the three air vents 10 for compressed air of the air distributor to pass through, compressed air can be supplied into the valve body from different angles, the uniformity of the compressed air entering the valve body is improved, and the working stability of the whole cylinder starting valve is improved.
