摘要： Provided is an actuator including a ball-type thrust amplifier therein that controls a valve in which a high-pressure fluid flows, and having less wear between members and a long lifespan. This actuator for a valve includes a thrust amplification mechanism therein, in which the thrust amplification mechanism includes a disk, a ball presser, a stem, and a plurality of balls that are sandwiched by and in contact with an upper surface of the disk, a tapered surface of the ball presser, and a tapered surface of the stem and disposed to move outward as the stem moves downward, the surfaces of the parts constituting the thrust amplification mechanism are coated with grease containing an additive, and the additive of the grease includes at least chloroalkane.

摘要： Provided is a small-sized controller capable of precisely controlling a flow rate of a high-pressure fluid. Between a working shaft of a drive device and a valve stem, a power transmission device is disposed to amplify a force acting on the working shaft and transmit the resultant force to the valve stem. A diaphragm as a valve element is made of metal and is deformable to: a state where a fluid passage is fully closed; a state where the fluid passage is fully open; or a state where the fluid passage is partially open. When the fluid passage is partially open, on the basis of the flow rate of a fluid flowing through fluid passages, the drive device finely adjusts the position of the working shaft such that the flow rate is constant.

摘要： Provided herein is a pipe joint of a relatively small joint diameter for use under ultrahigh pressure conditions. The pipe joint includes first and second joint members having mutually communicating fluid passages; and a gasket interposed between abutting end surfaces of the first and second joint members. The first and second joint members have ring-shaped seal projections formed at the abutting end surfaces thereof. The pipe joint satisfies a coefficient F of 0.4 or less in the following formula (1). F=(D32−D12)/(D42−D22), Formula (1): where D1 represents the inner diameter of the first and second joint members, D2 represents the inner diameter of the gasket, D3 represents the diameter of the seal projections, and D4 represents the outer diameter of the gasket.

摘要： Provided is a switching valve for use in an analyzer module for switching flow passages of fluids, in which the manufacturing cost is reduced and the life is increased. The valve element is provided with a lower contact portion that comes into close contact with a lower valve seat disposed at a valve body when a valve is closed, and with an upper contact portion that comes into close contact with an upper valve seat disposed at a counter plate when the valve is open. The counter plate has a first recess that is open downward and a second recess that is open toward the first recess and has a smaller horizontal cross-sectional area than that of the first recess, and the upper valve seat is press-fitted into the second recess.

摘要： Provided is a fluid controller in which reduction of the accuracy caused by the loosening of a screw portion and reduction of the durability caused by torsional stress are prevented. A stem vertical-movement-amount adjustment means 11 is provided with: a handle 41 which has a female screw 41b on an inner periphery thereof and which is rotatably supported by a casing 4; a movable body 42 in which a male screw 46b is provided on an outer periphery thereof and is screwed into the inner periphery of the handle 41; and a guide means 43 which prevents rotation of the movable body 42 relative to the casing 4 and which enables vertical movement of the movable body 42.

摘要： A first on-off valve (2) and a second on-off valve (3) each are a two-port valve. A first passage block (5) is provided with a first on-off valve-corresponding inflow passage (11) and a first on-off valve-corresponding outflow passage (12). A second passage block (6) is provided with a second on-off valve-corresponding inflow passage (14) and a second on-off valve-corresponding outflow passage (15). The second on-off valve-corresponding outflow passage (15) is in communication with an upstream side portion of the first on-off valve-corresponding outflow passage (12) via a communicating passage (13) formed in the first passage block (5). An orifice (20) is provided between the second on-off valve-corresponding outflow passage (15) and the communicating passage (13).

摘要： A valve element significantly improved in rotation preventing performance of an abutting member formed of a synthetic resin by using a caulking structure and a high-temperature-oriented valve provided with such a valve element. A valve element includes: an abutting member formed of a synthetic resin and configured to close a path opening by coming into abutment with a path opening edge, and a holding member having a recessed portion into which the abutting member is fitted, in which the holding member is caulked and thus the abutting member is held by the holding member. The holding member is provided with a plurality of notches at a portion to be caulked.

摘要： Provided is a fluid controller which enables precise flow-rate adjustment while securing the durability. The fluid controller includes a stem vertical-movement-amount upper-limit-value setting means 10 which sets an upper limit value of a vertical movement amount of a stem 8 associated with opening and closing operations. The fluid controller further includes a stem vertical-movement-amount fine-adjustment means 11 which changes the vertical movement amount of the stem 8 associated with the opening and closing operations, within a range of not greater than the upper limit value.

摘要： A fluid controller includes an automatic opening-and-closing device configured to move a valve rod upward and downward, and a manual opening-and-closing device configured to move the valve rod upward and downward by a manual operation. The manual opening-and-closing device includes a cylindrical handle supported by a casing so as to be rotatable and not to move upward and downward, and a cylindrical operating member screwed into a female screw of the handle and configured to move upward and downward with a rotation of the handle. The operating member is apart from a piston of the automatic opening-and-closing device in a vertical direction in an automatic operation. The piston is moved by the operating member which moves upward in association with the rotating operation of the handle in a manual operation in an opposite direction from the opening state brought by the automatic opening-and-closing device.
