Abstract

PURPOSE:To provide a cock having a liner mounted on a main body and a valve portion comprising a fixed disc and a movable disc, which is accomodated in the linear, which can closely adhere both discs with an elastic member. CONSTITUTION:An inflow port and an outflow port 8 are formed on a valve casing 3 disposed in a cock body, and a liner 11 is fitted to the interior of the valve casing. A fixed disc 15 and a spindle guide 50 are disposed on a fixed portion 36 of the linear 11, and a movable disc 16 is brought into sliding contact with the lower surface of the fixed disc 15 in such a manner as to freely slide. In this arrangement, the movable disc 16 is always pressed to the lower surface of the fixed disc 15 by an elastic member 37 such as a plate spring or the like mounted on the upper surface of the peripheral edge of an inlet 18 disposed on the lower surface of the liner 11, so that the upper surface of the movable disc 16 and the lower surface of the fixed disc 15 are watertightly brought into sliding contact with each other. Thus, an error in size of related parts will be absorbed to closely adhere both discs 15, 16 to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a water faucet, and more particularly to a water faucet in which a valve portion consisting of a fixed disk and a movable disk is housed in a liner, and the liner is attached to a main body.

<Prior Art> Conventionally, as this type of faucet, there is one disclosed in Japanese Patent Application Laid-Open No. 49-95228, as shown in FIG. 5, for example.

This thing consists of a fixed disk (101) and a movable disk (1
G2) are superimposed in a watertight and slidable manner, and a movable disk (
102) is inserted from below into a cylindrical liner (104) with its lower surface open while the rotation adapter (103) is engaged with its upper surface, and a tail bead (105) is attached to the lower surface of the liner (104) so that it cannot be separated. The connection prevents the operating part of the valve portion (106) from being changed in any way.

Therefore 1, this is the above part (101X102X10
3) (104) (105), even if there is a slight difference in dimensions, the fixed disk (101) and the movable disk (10
2) could not be brought into close contact with each other, and water leaked between the two, making it impossible to operate the valve portion (106) accurately.

<Problems to be Solved by the Invention> A problem to be solved by the present invention is to bring the fixed disk and the movable disk into close contact even if some dimensional errors occur in the parts.

Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to house a valve portion consisting of a fixed disk and a movable disk in the liner, and to attach the core liner to the main body. In the attached faucet, the fixed disk and the movable disk are pressed together by an elastic member.

<Function> The present invention uses an elastic member to absorb dimensional errors of parts and bring a fixed disk and a movable disk into close contact with each other.

<Example> An embodiment of the present invention will be described based on the drawings.

This embodiment shows a case where the faucet (D) is a so-called single faucet or a stop faucet, in which a valve part (3)' and one valve part (3)' is provided inside the main body (1), as shown in Fig. 1. It is.

The valve housing (3) is formed in a cylindrical shape, and has an inlet (4) communicating with the water supply side on its lower surface, an outlet (8) communicating with the water discharge side on its inner surface, and a liner inside. (11
) are removably fitted, and a cylindrical liner retaining piece (6) is provided protruding from the upper end.

The liner 411) is formed into a bottomed cylindrical shape having an outer diameter that is approximately the same as the inner diameter of the valve portion (3), and has an inlet 9 o'clock on its lower surface that communicates with the inlet (4) of the valve portion (force). , valve part (3
) are opened so as to face each other and communicate with the outflow ports (8) of ), and a lid is provided at the upper end, and the lid is attached to the liner retaining piece (6). By screwing the liner (IJI) on and off from the valve housing (3), it is a cartridge type that is easy to attach and detach.

In addition, a fixing part (to) is provided protruding from the inner peripheral surface of the lower part of the liner (b), and a fixing disk (g) and a spindle guide are sequentially stored and arranged on the fixing part (c), and the spindle guide - By screwing a cap screw from above into the internal thread 0◆ cut into the inner peripheral surface of the upper end of the liner α9, the fixed disk (to) and the spindle guide are fixed non-rotatably.

When the fixed disk is q, it is made of a highly wear-resistant material such as sintered metal, ceramic, or alumina oxide (A420g), and is formed into a disk shape that comes into contact with the inner peripheral surface of the cylinder CI, with a spindle (c) rotating in the center. Through hole 61) that can be freely pushed through
At the same time, two inflow holes 91911 are opened on a concentric circle.
Open the holes facing each other.

The spindle guide has a spindle (C) inserted in the center so as to be rotatable in the vertical direction, and a communication recess (C) on the bottom surface that communicates with the inflow hole tel (C) of the fixed disk α→.
, and the communicating recess (to) is connected to the outlet 1 of the liner (b).
It is connected to zl.

On the other hand, the movable disk (I) is mounted on the lower surface of the fixed disk (G).
Q is slidably brought into sliding contact.

The movable disk <■l is made of the same material as the fixed disk (11) and is formed in the shape of two blades so as to be able to cover the polished surface of the inlet hole (c) Q of the fixed disk (a). By inserting and locking the shaft, the shaft rotates and slides as the handle that is engaged with the upper end of the spindle The valve portion is configured to open and close.

Also, the movable disk μ→ is the entrance 0 on the bottom surface of the liner (B)→
An elastic member C3'I such as a leaf spring provided on the upper surface of the circumference is always forcibly pressed against the lower surface of the fixed disk (11), and the upper surface of the movable disk uQ and the lower surface of the fixed disk (G) are slid in a watertight manner. I'm letting you touch me.

Furthermore, in the figure is a stopper that restricts the rotation of the movable disk αQ.

Therefore, this is the upper end of the liner μ platform or the grip part (
Since there is no notch or protrusion that restricts the rotation of the movable disc 9 in the part that can be seen from the outside of (b), it has the advantage of not detracting from the aesthetics, and the molding of the notch or protrusion does not affect the aesthetics. steps can also be eliminated.

The structure of the main body of the faucet is not limited to a single faucet or a stop faucet as shown in the diagram, but may also be a mixed faucet that has two valve parts on the main body to adjust the flow rate of cold water and hot water. It goes without saying that the movable disk is in sliding contact with the lower surface of the fixed disk, but the movable disk is also slid on the upper surface of the fixed disk.

You may also make them touch each other.

<Effect of the invention> Since the present invention has the above configuration, it has the following advantages.

■ Since the fixed disk is pressed into contact with the movable disk by an elastic member, even if there is a dimensional error in the parts, this error can be absorbed and both disks can be brought into close contact, eliminating the possibility of water leakage as with conventional models. It is possible to accurately operate the valve portion without causing any problems.
