摘要： The present invention relates generally to a pendulum valve that is installed in a connection pipe connecting a vacuum pump between the chamber of a dry etching apparatus and the vacuum pump in the etching line of a semiconductor manufacturing process and adjusts the amount of gas, and more particularly to a pendulum valve that includes a fixed housing configured such that a shaft coupled to a valve gate for adjusting the amount of gas is closely fixed to a valve housing through an O-ring and a rotation shaft (an internal shaft) coupled to the inside of the fixed housing, so that only the rotation shaft separate from the value housing is rotated by using a lip seal as a rotation axis, thereby suppressing the discharge of unnecessary particles and hardened substances while maintaining the sealing characteristics of the pendulum valve.

摘要： Pressure-reduction devices for fluid systems are disclosed. An example device includes a housing defining an axial fluid passageway between an inlet and an outlet. A first plate is fixed to the housing and positioned in the axial fluid passageway. A second plate is positioned adjacent the first plate in the axial fluid passageway. The second plate is moveable relative to the first plate between a first position to move the pressure-reducing device to a closed position to restrict or prevent fluid flow through the axial fluid passageway and a second position to move the pressure-reducing device to an open position to allow fluid flow through the axial fluid passageway.

摘要： A safety device for hydrodynamic pressure regulating pipe network includes a gate valve, which comprises at least a valve body and a gate. A water inlet of the gate valve is used to be connected to a water inlet pipeline. A hydraulic driving device, which comprises a hydraulic cylinder, is also included. The hydraulic cylinder includes a cylinder body, a piston and a piston rod. The piston rod is connected to the gate. The lower part of the inner cavity of the cylinder body is connected to the water inlet pipeline through a gate opening power pipelines. The upper part of the inner cavity of the cylinder body is connected to a gate closing driving device, which is used to drive the gate and close the gate valve.

摘要： Provided is a gate valve with a disk replacement structure. The gate valve is installed on a pipe, and comprises: a valve body having a blocking space formed therein, a pair of flange pipes formed to communicate with the blocking space, and a cover mounted on an upper side thereof to close the blocking space; a disk arranged in the blocking space to be lifted and provided with a mounting hole which is formed on an upper surface thereof and has a lifting nut therein; and an operating rod installed on the cover to lift the disk. An insertion hole is formed on the cover to penetrate the cover.

摘要： An embodiment includes a gate valve comprising: a valve body including a cavity coupled to a channel having proximal and distal portions; a gate to seal and unseal the channel; proximal and distal seats adjacent the gate; wherein (a) the proximal seat traverses towards the gate and stops at a first position when the gate is closing and the proximal channel portion is more highly pressurized than the cavity, and (b) the distal seat slides away from the gate and stops at a second position when the gate is closing and the cavity is more heavily pressurized than the distal channel portion. Other embodiments are described herein.

摘要： A gate valve that opens or closes opening parts of a valve box with a valve plate includes a valve rod that moves upward or downward and tilt inside the valve box; a drive mechanism that moves the valve rod upward or downward by a predetermined stroke and tilts the valve rod; a stopper mechanism that includes a spring return type stopper pin, and in which, when compressed air is supplied, a pin rod of the stopper pin moves forward in a horizontal direction, and a cam plate connected to the valve rod or a load receiving roller attached to the cam plate collides with the pin rod to regulate an upward movement of the valve rod. When the supply of the compressed air is stopped, the pin rod moves backward in the horizontal direction due to a reaction force of the spring, so that the cam plate or the load receiving roller does not collide with the pin rod and the regulation on the upward movement of the valve rod is released; and a vibration reducing device that reduces vibration.
