Abstract

PURPOSE:To make on-off operating force yet larger, by installing a ball valve housing concave part in a way of letting it incline to the upstream side proximate to a valve seat from a flow passage, while forming a flow passage wall, corresponding to both of the valve seat and the ball housing concave part, with an elastically deformable material. CONSTITUTION:A couple of valve seats 4 are made up inside a main body A consisting of an elastic tube of rubber or the like, while an inlet 51 of a ball valve housing concave part 5 is situated on the middle between these valve seats 4 and 4. In a state of being valve-opened, a ball valve 11 comes close to both these valve seats 4 whereby even if either of them in the main body A comes to the upstream side, it becomes a shutoff state in a flow passage anyway. When a tube wall 41 between these valve seats 4 and 4 is pushed upward, the ball valve 11 is fitted inside the ball valve housing concave part from the inlet 51, thus the flow passage is opened. In addition, when a top wall 52 of the housing concave part 5 is pressed downward, the ball valve 11 slips out of the inlet 51 and is pressed in space between these valve seats 4 and 4, thus valve opening is performable.

Pinch pulp is a type of valve whose operating means does not penetrate γ during the flow path, but this is a valve that blocks the flow path by crushing the elastic tube that makes up the IL path, and is not one that is opened and closed repeatedly.

１記ピンチパルプに於けるような不都合は生じない。On the other hand, a valve body is known in which a steel ball (1) is used to construct the valve body, and the valve body is opened and closed by the operation of a permanent magnet (2) or an electromagnet provided outside the flow path. (Fig. 1) In this case, the steel ball 1) acts as a valve body, and the flow path (3)
Because it is in contact with the valve seat (4) formed inside,
1. There is no problem as in the case of pinch pulp.

い。However, the steel ball (1) is held by the magnetic force from the permanent magnet (2) and the electromagnet, and the permanent magnet or electromagnet is moved! 1lIJK
Therefore, since the steel ball (1) is used to open and close the punch OJ,
It cannot be used in applications that require large force to open or close a valve.

させ得るようにするこ七をその課題さする。The object of the present invention is to enable a spherical cell such as a steel ball to be fully opened and closed by a mechanical external force from outside the flow path in order to increase the acting force.

したことである。The technical means for solving the above problem is to provide four ball valve housing sections on the upstream side near the valve seat, deviating from the flow path, and J to the valve seat and the ball valve f-accommodation recess i1ζ. The ML path wall is made of an elastically deformable lunate, and in the valve open state, 11 ball sockets are inserted and held in the ball socket housing recess 31X.

従って、ブ↑−座は開放状態にあり、］＞Ｒ升は流路か
ら偏った位置に保持されているから、流路も「開」とな
る。Therefore, the ↑- seat is in an open state, and since the ]>R square is held at a position offset from the flow path, the flow path is also "open."

体内の流路は該体弁により遮断される。Next, by mechanically deforming the wall surface of the housing recess, the ball valve escapes from the four housing parts and is fitted into the valve seat, whereby the flow path within the main body is blocked by the body valve.

れる。In order to open and close the flow path from this state, it is sufficient to mechanically deform the flow path wall of the fr-floor component and then fit the internal body valve into the bulb housing, thereby opening the flow path. It will be released.

る。従って、圧力の高い流体にも適用できる。Since the flow path is opened and closed by mechanically deforming the tube wall made of elastic paulownia material, the opening and closing action force can be greater than that which opens and closes the ζ valve using magnetic force. Therefore, it can also be applied to high pressure fluids.

= There is no need to worry about valve closing failure due to Jyo.

In order to eliminate the defect of the thread, it is sufficient to adopt a structure in which the elastic tube is coated with 1M4 cloth, nonwoven fabric, etc., or it is inserted into the section mJ.
