係るものである。[Detailed description of the invention] This invention minimizes the contact surface between the switch and the members that come into contact with it, greatly reducing wear due to mutual contact, and also raises and lowers the switch. This invention relates to a push cock that allows fluid to flow and shut off quickly and reliably.

開口して流体が矢印方向に流動可能となる。For example, in a conventional cock, as shown in FIG. A handle 5 is fixed to the square part of the upper end of the switch 4 which is rotatably tightly fitted and fitted, and when the handle 5 is rotated, for example, 90 degrees from the position shown in the horizontal plane on a horizontal plane, the handle 5 is attached to the switch 4. The through hole 6 opens to both the inflow hole 2 and the outflow port 3, allowing fluid to flow in the direction of the arrow.

しかしてこのような開閉子４の回動する形式のコックに
あっては、ハンドル５の度重なる回動により開閉子４の
外周面の大部分が本体１の内壁ｉと常時接触するので、
次第に開閉子４と内壁ｉとは摩耗して両者間に隙間が発
生することになる。However, in such a type of cock in which the switch 4 rotates, most of the outer peripheral surface of the switch 4 is constantly in contact with the inner wall i of the main body 1 due to repeated rotations of the handle 5.
Gradually, the switch 4 and the inner wall i will wear out, and a gap will be created between them.

そしてこの隙間の発生で流体の一部が外部に漏洩するよ

ず、しかも流体の流通と遮断とを確実かつ迅速に行ない
難い等の欠点を免れ難い。When this gap occurs, a part of the fluid leaks to the outside, and therefore, in order to eliminate the gap, it is necessary to correct the switch 4 and the inner wall i again so that they are in close contact with each other, and the correction work itself is also Since it requires time and effort, it is rather uneconomical for the user. On the other hand, the operation of forward and reverse rotation of the handle 5 to a predetermined position before and after use is not troublesome, and furthermore, it is difficult to circulate and cut off the fluid. It is difficult to avoid drawbacks such as difficulty in performing the process reliably and quickly.

In addition to minimizing wear and tear to a large extent and preventing fluid leakage from occurring, the switchgear set at a predetermined location can be used to ensure fluid circulation and shutoff. The purpose is to provide a push cock that can be reliably held at the initial setting position unless external force is applied.
The switch opens and closes the communication chamber, and is constantly pushed upward by a coil spring housed in the communication chamber.
In a push cock that is installed below the lifting rod that moves up and down within the holding frame and allows the communication chamber to be opened and closed by raising and lowering the lifting rod, a part of the periphery is cut out in the reduced diameter part directly below the pressing part formed at the upper end of the lifting rod. An elastic tapered ring is loosely fitted and locked, and the tapered ring is removably exposed to a recess in the cover and a floating recess in the holding frame.

The lower part of the communication chamber 24 interposed between the and the outflow hole 23 is closed with a lid 25, and the male screw K of the lid 25 is removably screwed into the female screw carved on the periphery of the bottom opening of the holding frame 21. On the other hand, a male screw b carved on the upper outer peripheral edge of the holding frame 21 is screwed into a female screw carved on the lower side of the cover 26, which has a U-shaped cross section on the road side, so that it is integrated with the holding frame 21.

The communication chamber 24 is placed in a closed state.

1 is pressed and lowered, the switch 28 descends against the elastic force of the coil spring 27, and the inflow hole 23 and outflow hole 22 communicate with each other via the communication chamber 24, and the fluid flows in the direction of the arrow. , the tapered ring S descends while being pressed on the outside, reaches the floating recess t, expands again due to elasticity, and the upper part of the tapered ring S is stopped by the upper wall of the floating recess t, so that the lifting frame 29 Since the switch 28 is held at a fixed position, the fluid can continue to flow in the direction of the arrow.

制止されることになる。) Next, when the pressing part 31 is pressed downward, a part of the lower part of the tapered ring S is pressed and reduced toward the reduced diameter part 30 by the inner peripheral edge of the floating ring 32, (the tapered ring S is As a result, the upper part of the taper ring S, which has been expanded until now, is also reduced, and the whole becomes temporarily cylindrical. When the pressure of the pressing part 31 is released, the coil spring springs up. The upward elastic force of the opening/closing member 27 and the lifting frame 29 are instantly pressed upward, and the tapered ring S, which had temporarily become cylindrical, returns to the shape shown in the figure due to its own elasticity. , enters the recess V.
It will be stopped.

益を有するものである。According to this invention, a coil spring housed in a communication chamber interposed and communicating with the inflow hole and the outflow hole constantly springs upward the switch that opens and closes the communication chamber, thereby keeping the communication chamber in a closed state. The lifting frame with this opening/closing element attached to its lower end can be raised and lowered within the holding frame, so the communication chamber can be opened and closed by the opening/closing element by raising and lowering the lifting frame. Compared to conventional rotary type cocks that flow or shut off fluid, it is more reliable and quick in terms of fluid flow or shutoff, and because the switch rotates, it stays in close contact with the switch. Compared to conventional cocks, where the surrounding wall and the switch itself gradually wear out with repeated use, eventually leading to fluid leakage, its structure also includes a part of the switch and the inner wall of the communication chamber. The contact surface is significantly reduced, with only a small portion of the contact touching, and even if there is some wear, the elastic force of the coil spring can push the switch toward the communication chamber, which is convenient. The taper ring loosely fitted into the reduced diameter part of the frame is shaped like a bullet with a part cut out on its periphery, so the taper ring can easily deform as the elevating frame goes up and down. Therefore, there is no risk of damage or destruction, and by locking the tapered ring in the recess in the cover and the floating recess in the holding frame, the lifting frame can be reliably held in its original position. However, unlike the case where there was a risk of the lifting frame being displaced unexpectedly, there is no fear of accidental fluid leakage or blockage, and the lifting and lowering of the lifting frame is an extremely simple operation. It can circulate and shut off fluid, making it easier for users to handle than conventional rotary cocks, and the overall structure is not significantly more complicated than conventional cocks. Therefore, it has practical benefits such as being robust and can be manufactured at low cost.
