An angle of repose valve for controlling the flow of granules and a method of repairing a leak in an angle of repose valve are disclosed herein. The angle of repose valve has a housing with an interior cavity, an inlet, and an outlet. A gas is used to convey granules through the valve and the housing has a thickness such that the gas can have a pressure of at least 70 psi. A saddle is disposed in the interior cavity of the housing and is coupled to a rotatable shaft that passes through an opening in the housing. A chevron seal is disposed between the shaft and a sealing member. A compression member is threadably engaged with the sealing member and is operable to exert force on the chevron seal to expand the chevron seal against the shaft and/or the housing to prevent and/or repair leaks of gas therethrough.

For pulsed injection of liquids into the ground, the tool has a rotating cylinder, having through-slots. The tool has an insert, which is pressed against the rotating cylinder. As the cylinder rotates, the slots in the rotor cover/uncover the slots in the insert, creating the required pulses. By suitably shaping the slots, the pulses can have a fast rise-time from closed to open. The insert is shaped to minimize flow interference.

The present invention discloses a member biasing apparatus (900) to bias a closure member (102) of a valve (901) along the longitudinal axis of a shaft (911) within a bore (956) of a valve body (924), the closure member biasing apparatus comprising a first spring seat (902) formed on a distal end (903) of the shaft (911). Further it comprises a second spring seat (904) formed on an end of a follower spacer (909), and a wave spring (906) disposed between the first and second spring seats, wherein the first spring seat forms a first seating surface and the second spring seat forms a second seating surface, and wherein the first and second spring seats form a body sized to be at least partially disposed within the bore (956) of the valve body.

Dichtungsanordnung für einen Drehschieber, aufweisend ein Querschnittsverstellglied 1 mit einer Mantelfläche 2, die mindestens eine Durchgangsöffnung 3 aufweist, sowie mindestens einen an dem Querschnittsverstellglied 1 angrenzenden Rohrabschnitt 4 mit einem Einlass, der durch eine Verdrehung des Querschnittsverstellglieds 1 um eine Rotationsachse B in zumindest teilweise Überdeckung mit der Durchgangsöffnung 3 gebracht werden kann, wobei entlang der axialen Erstreckung A des Rohrabschnitts 4 ein erstes Dichtelement 5, ein zweites Dichtelement 6 und eine Vorspanneinrichtung 7 angeordnet sind, die einen Durchflusskanal für ein Fluid bilden, wobei das erste Dichtelement 5 an der Mantelfläche 2 des Querschnittsverstellglieds 1 dichtend anliegt und wobei das zweite Dichtelement 6 elastisch ausgebildet ist und zwischen dem ersten Dichtelement 5 und der Vorspanneinrichtung 7 angeordnet ist.
摘要:
A foam gun having a spool valve (65) with a product passage (67) received in a housing (16) shaped to accommodate the spool valve (65). The housing (16) having an outlet passage (46) and inlet passage (69) and a thin sidewall portion (61) surrounding part of the spool valve (65). A stub cylinder (118) having an opening and stub cylinder portions (122) is integrally formed with the thin sidewall portion (61). A cylindrical force-applying fitting (110) is provided having a through bore (116) matching the opening in the stub cylinder (118) and having a radial flange (112) engaging the stub cylinder (118). The radial flange (112) of the fitting (110) is urged into a compressive position with the stub cylinder (118) by a hose portion (86) and held in place by a set screw (92). A sufficient compressive force is applied to the stub cylinder (118) to distort the stub cylinder portions (122) into contact with the spool valve (65) to form a seal between the thin sidewall portion (61) and the spool valve (65).
摘要:
A 'plug and play' process control valve 10 providing closed loop feedback control has a built in microprocessor 40, stepper-motor 20, a position encoder, a valve body having an inlet 11 and an outlet 12, and pressure sensors 30, 31 positioned within the inlet 11 and the outlet 12 of the valve body, the pressure sensors being connected to the microprocessor 20, which is in turn connected to an input from the position encoder, and provided with outputs to the stepper-motor 40. Within the valve body there are a pair of apertured ceramic shear action discs 13, 14. The stepper-motor rotates the upper disc 14 relative to the apertured stator disc 13 to control pressure or flow in the pipeline.

There is provided a high-precision throttle valve (60) that has a small loss of pressure and is capable of easily regulating a flow rate. Furthermore, there is provided a weft insertion apparatus in a jet loom provided with a throttle valve having such characteristics. The throttle valve of the present invention includes a valve hole (63) bored so as to be orthogonal to a fluid channel (62) and a valve body (64) inserted into the valve hole (63) so as to be rotatable about an axial center, in which a concave engraved portion whose depth is continuously varied in a circumferential direction is formed on a circumferential surface of the valve body (64) at a position corresponding to an opening of the fluid channel (62). Furthermore, a weft insertion apparatus in a jet loom of the present invention includes the throttle valve, and the fluid channel connects a compressed air source regulated for pressure in a jet loom to a nozzle for injecting the compressed air.

Ein Drehwegbegrenzer, der zwischen einer Betätigungsvorrichtung (22, 23) zur Erzeugung einer Drehbewegung eines zu drehenden Bauteils (19) und einem mit der Betätigungsvorrichtung (22, 23) durch Verbindungsmittel (21) verbundenen Anschlußflansch (20) angeordnet ist, und der aus einer mit dem Anschlußflansch (20) in Wirkverbindung stehenden, eine Mittelöffnung (4) mit in diese hineinragenden Anschlagsflächen (13, 14) zur Aufnahme eines mit dem zu drehenden Bauteil (19) in Wirkverbindung stehenden Drehteils (11) aufweisenden Vorrichtung besteht, soll auf möglichst einfache Weise zuverlässig die Endpositionen einer Drehbewegung festlegen. Die dazu notwendigen Vorrichtungen bestehen aus einer Vielzahl von verschiedenen Bauteilen. Zur Vereinfachung besteht die vorgeschlagene Vorrichtung aus zwei mit Anschlagsflächen (2, 3) versehenen, scheibenförmigen Bauteilen (1, 1'), die identisch ausgebildet und verkehrt herum aufeinandergelegt sind (Fig. 5).
摘要:
A random orbital sander has improved arrangements (24), (88), (90), (120) for resiliently supporting an air motor (32), controlling the flow of pressurized air to the motor and utilizing air exhausted from the motor to withdraw dust from a shroud (120) arranged to collect dust generated incident to the operation of the sander. Also disclosed is an alternative dust collecting arrangement wherein the shroud is connected by a sander-mounted duct (120d) to a vacuum source.
