Stop valve operation handle

Abstract

To solve the problems that conventionally, a stop valve that moves a valve body up and down by rotating the valve body several times requires time and effort to operate for rotation, and that since storage spaces under a kitchen and the like are narrow spaces through which drainage pipes and the like pass, objects or people's bodies may come into contact with a lever handle when putting things in or taking things out of the storage spaces or cleaning the storage spaces, which causes incorrect operation.SOLUTION: A ball stop valve is set at a connection part between an end part of a pipe and a faucet instrument, the ball is rotated to open and close a water hole, and a convex fitting body 21a is set on a covering operation body, and even when a cover body is rotated in a state where the convex fitting body is not fitted in a rotational direction into a fitting recess part 21b set on an inner wall of the cover body that rotatably covers the covering operation body, the cover body 4 rotates freely to prevent change in a set flow rate due to inadvertent contact or erroneous operation.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a handle for a flow rate adjusting ball stop valve used for hot and cold water supply piping in a house, which is configured so that the set flow rate is not changed inadvertently. [Background technology]

[0002] The water supply and hot water piping in a home is passed under the floor or ceiling using plastic pipes and fittings, and is connected to end appliances such as the kitchen, bathroom, and toilet. Conventionally, stop valves that move the valve up and down by rotating it several times have been used to adjust the flow rate or when replacing faucets.

[0003] For example, the invention described in Patent Document 1 describes a stop valve that divides a passage hole 11 into an upstream portion and a downstream portion by a valve seat 12, and opens and closes between the upstream portion and the downstream portion by a valve body 2 that seats on and moves away from the valve seat 12. In contrast, a flow adjustment ball stop valve opens and closes the water hole by rotating a ball at the connection between the end of the pipe and the faucet, and the flow rate to the faucet can be adjusted by the opening and closing angle of the water hole, or the water can be stopped when replacing the faucet, etc.

[0004] There are two types of flow adjustment ball stop valves: one that opens and closes the ball with a lever handle, and the D-type that opens and closes with a flathead screwdriver or coin, etc., and each type is used depending on the usage environment. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2004-293096 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, stop valves that move the valve up and down by rotating the valve body several times, as in the invention described in Patent Document 1, require time and effort to operate. Also, with conventional lever handle types, storage spaces under kitchens and other areas are narrow spaces with drainage pipes and the like, and there is a risk that objects or the body may come into contact with the lever handle when putting things in or taking things out of the storage space or cleaning, resulting in incorrect operation.

[0007] In addition, the conventional lever handle type and the D-type stop valve operated with a flat head screwdriver or coin, etc., have a problem that the body and the stopper rod are not interchangeable, so they require separate parts for turning operation, resulting in high management costs.

[0008] The present invention is intended to address the above-mentioned problems, and provides a handle member that is attached to the ball rotating plug of a ball stop valve, and that comprises a covering body that attaches the ball rotating plug to the ball rotating plug so that the plug can be rotated, and a cover body that has an engaging recess on its inner wall surface that rotatably engages with a convex engaging body set on the outer periphery of the covering body. Effect of the Invention

[0009] Since the present invention is configured as described above, the water hole can be opened and closed by rotating the ball at the connection between the end of the piping and the faucet without the troublesome operation of rotating the valve body multiple times and moving it up and down, and even if the cover body is rotated when the convex fitting of the covering operation body is not engaged with the fitting recess on the inner wall of the cover in the rotational direction, the cover body on the outside of the covering operation body will spin freely and the ball rotation plug will not move, so the ball will not rotate, and it is possible to prevent changes in the set flow rate due to inadvertent contact or erroneous operation.

[0010] Conventional flow regulating ball stop valves, Type D, required management costs because the ball rotating valve body could not be used in conjunction with the lever handle type. However, according to the present invention, parts other than the handle portion can be used in conjunction with the lever handle type and Type D, reducing management costs and also making it possible to replace and install on existing lever handle types. As the type can be changed simply by replacing the handle parts, it is possible to immediately respond to changes in the setting environment. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the present invention will now be described with reference to the drawings. Reference numeral 1 denotes a stop valve operating handle, which comprises an overlying operating body 21 that is attached to perform the rotational operation of the ball pivoting plug body 2 of a ball stop valve A, a convex fitting body 21a that is attached to the overlying operating body 21 and set on the outer periphery of the overlying operating body 21, and a cover body 4 that has an engaging recess 21b on its inner wall surface that rotatably fits into the overlying operating body 21. The handle is attached to the top of the ball pivoting plug body 2, and is used to rotate the ball B of the ball stop valve A to open and close the valve by changing the angle that the ball water passage B1 makes with the piping water passage W (from 0° coaxially to 90° perpendicularly), as well as to adjust the flow rate to the faucet and to stop water flow when replacing the faucet, etc.

[0013] The piping water passage W is a water passage that is opened and closed by the ball stop valve A, and has a joint mechanism for jointing the hot and cold water supply pipes. A fitting rotation operation mechanism 3 that operably captures the top of the ball rotating plug 2 is formed on the inner circumference of the covering operation body 21 that performs the rotation operation of the ball rotating plug 2, and is configured to capture the top of the ball rotating plug 2 only in a specific direction and angle range.

[0014] That is, as shown in Figure 8, the fitting and rotating operation mechanism 3 forms a flathead screwdriver insertion groove M on the upper edge of the cylindrical space for covering of the covering operation body 21, forms a cylindrical wall 22a in the cylindrical space for covering, forms a stopper 22b on its inner circumference, and further forms a semi-cylindrical wall 23 that covers about two-thirds of the end face circle of the cylindrical wall 22a.

[0015] The covering operation body 21 constructed as described above engages with the recess 26 of the ball rotation plug body 2 formed corresponding to the stopper 22b, and is covered by the ball rotation plug body 2 while the flat surface 24 on the inner circumference of the cylindrical wall of the covering operation body 21 and the cutout surface 25 of the ball rotation plug body 2 come into contact with each other.

[0016] The covering operation body 21 and the cover body 4 are made of resin (e.g., polyacetal resin) and are assembled by snap-fitting the convex fitting body 21a of the covering operation body 21 into the fitting recess 21b of the cover body 4. Because of the snap-fit ​​fitting, they do not easily separate in the axial direction but can easily rotate in the circumferential direction. Since the covering operation body 21 is covered by the cover body 4, the ball rotation plug body 2 is not operated by the rotation of the cover body 4. As described above, when the cover body 4 rotates, there is no engagement between the convex engagement body 21a and the engagement recess 21b in the rotation direction, so the cover body 4 idles and rubs against the peripheral surface of the covering operation body 21.

[0017] The ball rotating plug 2 is operated by inserting a coin or the like into the flathead screwdriver insertion groove M of the cover operating body 21 and rotating it. In this case, the cover operating body 21 is attached to the ball rotating plug 2 in such a manner that a rotating force is transmitted by the contact surface between the flat surface 24 on the inner circumference of the cylindrical wall and the notched surface 25 of the ball rotating plug 2, so that the ball stop valve A can be opened and closed. [Industrial Applicability]

[0018] The stop valve operating handle of the present invention opens and closes the water hole by rotating a ball at the connection between the end of the piping and the faucet, and is configured so that when the convex fitting of the covering operating body is not engaged with the fitting recess on the inner wall of the cover in the rotational direction, the cover body on the outside of the covering operating body spins freely even when the cover body is rotated, preventing changes to the set flow rate due to inadvertent contact or erroneous operation.The water hole can be opened and closed by rotating a ball at the connection between the end of the piping and the faucet, without the troublesome operation of rotating the valve body multiple times and moving it up and down. In other words, even if the cover body is rotated when the convex fitting of the attachment operation body is not engaged with the fitting recess on the inner wall of the cover, the cover body on the outside of the attachment operation body will spin freely and the ball rotating plug will not move, so the ball will not rotate, preventing changes to the set flow rate due to inadvertent contact or erroneous operation, and therefore has high utility in the water facilities industry.
