摘要： A rupture disk system has a housing defining a central axis, a first axial end defining an axial opening and a second axial end. An airflow pathway extends from the first axial end facing towards the second axial end. A sealing surface is defined about the airflow pathway towards the first axial end. A shield extends across the airflow pathway on the second axial end. Radial openings are defined around the central axis, where the radial openings are positioned between the first and the second axial ends, such that the airflow pathway extends from the axial opening to the radial openings. A rupture disk is coupled to the housing across the airflow pathway. The rupture disk has a polymeric layer. The rupture disk has an unweakened region having a first thickness and a weakened region having a second thickness. A threshold rupture pressure is defined by the weakened region.

摘要： An electric valve can be further miniaturized while reducing the number of manufacturing man-hours. The electric valve contains: a motor including a stator member and a rotor member that displace a valve body, and a housing for accommodating the motor. The housing is formed by joining a heat generation portion formed of a first material to a heat receiving portion formed of a second material. The light transmittance in the first material is lower than the light transmittance in the second material.

摘要： Provided is a combination structure of an electronic water valve including an electromagnetic unit including a coil body and a yoke having an upper support plate and a lower support plate and which includes a valve body including an upper member and a lower member. The combination structure includes a locking long hole formed in each of opposite sides of the lower support plate, an elastic pressing rod that protrudes, a protrusion locking rod formed on each of opposite sides of an upper portion of the upper member, and a burr blocking member which is formed on an outer circumference of the upper member and which prevents a welding burr from being exposed to an outside of an outer circumference of the valve body through a gap of a friction welding portion, the welding burr being generated when friction welding of the upper member and the lower member is performed.

摘要： A guide frame for a four-way reversing valve is provided. The guide frame includes a frame body. Both ends of the frame body are provided with a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion is provided with a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the outer side of the first bending member by welding, and the second reinforcing plate is connected to the outer side of the second bending member by welding. Optionally, the first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.

摘要： A valve in which a backseat structure is formed at a height to easily prevent penetration of fluid with high accuracy from outside a bonnet to inhibit an increase in internal pressure. In a state in which a packing for sealing (5) is attached inside a bonnet (10) in a longneck structure, a stem (3) is axially inserted and a flow path (13) inside a valve box (2) is provided to be opened and closed by a valve body (4). The bonnet is divided into an upper bonnet (11) and a lower bonnet (12) at a position higher than a position at which a fluid flowing inside the valve box ascends in a liquid state. A backseat mechanism (42) has a fixed-side seal surface (21) formed on a lower end side of the upper bonnet and a movable-side seal surface (41) on an outer peripheral surface of the stem.

摘要： An electric valve includes a stator assembly, a rotor, a circuit board assembly, a sleeve and a valve assembly. The stator assembly is arranged around the rotor. The sleeve isolates the stator assembly from the rotor. The stator assembly is electrically connected to the circuit board assembly. A valve port is formed in the electric valve. The rotor can drive the movement of the valve assembly with respect to the valve port. The electric valve further comprises a box body. The circuit board assembly is arranged in the box body. The box body includes a shell and a cover body. A seal ring is arranged at a joint of the shell and the cover body. The seal ring is compressed between the shell and the cover body. The cover body is fixedly connected to the shell by means of welding.
