れる。2. Description of the Related Art A gauge valve is also called a gauge valve,
It is a valve used as a source valve for pressure gauges and gauges. This gauge valve is used for the purpose of adjusting the flow rate by opening and closing the gauge valve to protect the pressure gauge and the like from pulsation and the like. Alternatively, the gauge valve is used for the purpose of temporarily removing the pressure gauge or the like by closing the valve during maintenance / inspection or repair of the pressure gauge or the like.

る。Gauge valves that are generally commercially available include
A valve having a needle type valve body is used so that the flow rate can be easily adjusted. In addition to those sold as gauge valves, valves sold as general miniature valves and needle valves are also used in place of gauge valves. In addition, the valve body is not a needle type, gauge cock or ball valve,
A ball valve is also used as an alternative to a gauge valve.

さらに、弁体の位置、すなわち弁がどの程度開いている
のか外観からは分からないという問題があった。However, it is difficult to finely adjust the flow rate of a gauge valve having a valve body other than the needle type, and it is difficult to adjust the opening of the valve so as not to be influenced by pulsation. Therefore, the valve body is preferably a needle type gauge valve. On the other hand, in a general needle type gauge valve, the handle for opening and closing the valve element has to be rotated many times, which makes the opening and closing operation complicated.
Further, there is a problem that the position of the valve body, that is, how much the valve is open cannot be known from the appearance.

Is an inflow port 16 into which a fluid flows, an outflow port 18 from which the fluid flows out, a fluid passage 20 provided between the inflow port 16 and the outflow port 18, and a valve portion that opens and closes the passage 20. 22 is provided. The appearance of the body 12 is a hexagonal column in the present embodiment, but may be a columnar shape and is not limited. A pipe led from a pipe or the like whose pressure is to be measured is connected to the inflow port 16. On the other hand, outlet 1
A pressure gauge or a gauge is connected to 8 and the inlet 1
The fluid introduced from 6 is led to a pressure gauge or the like. The diameter and the like of the passage 20 are set so that the pressure is smoothly propagated without causing a pressure loss. After the fluid is introduced into the pressure gauge or the like, the passage 20 only propagates the pressure of the fluid, and there is almost no flow of the fluid.

The needle valve body 26 is integrally formed with a screw portion 28 for operating the needle valve body 26 and a shaft portion 30. On the other hand, a handle 32 is attached to the other end of the shaft portion 30 with a screw 31. The screw portion 28 and the shaft portion 30 are axially supported by the support member 34, and in particular, the screw portion 28 is screwed into a female screw portion 36 formed on the support member 34.
The support member 34 is fixed at a predetermined position on the body 12. Therefore, by rotating the handle 32, the screw portion 28 rotates together with the shaft portion 30 to move the needle valve body 26 forward or backward, and the valve portion 22 including the needle valve body 26 and the valve seat 24 is opened and closed. Adjusted.

The distance from the pitch to about 3/4 pitch, particularly about 1/4 pitch, is formed as the moving distance between the closed position and the open position of the needle valve 26. That is, the handle 32 is rotated clockwise or counterclockwise from about 1/6 rotation (60 degrees) to about 3/4 rotation (270 degrees), particularly about 1/4 rotation (90 degrees).
By rotating the needle valve body 26, the needle valve body 26 can be opened and closed. As a more preferable aspect, when the needle valve body 26 is rotated 90 degrees with the closed position as a reference, the gap between the needle valve body 26 and the valve seat 24 may be in a substantially fully opened state. In either case, the angle is ± 3
An error of about 0 degree is allowed.

It is preferable that the cut parallel surfaces 33 are formed so as to have directionality. By making the shape of the handle 32 directional, it is possible to easily know the open / closed state of the needle valve 26 by observing the state of the handle 32.

The fluid introduced from 16 is guided to the pressure gauge or the like through the outlet 18. Further, when the direction of the parallel surface 33 of the handle 32 is perpendicular to the flow direction of the fluid shown by the arrow in FIG. 3, the needle valve body 26 is in the closed state shown in FIG. The generated fluid is stopped by the valve portion 22 provided in the passage 20.

The present invention is not limited to the one having the direction indicating function as shown in (1), but may be any one that can know the opening degree of the needle valve body by looking at the handle, and is not particularly limited. For example, an indicator member such as an arrow may be provided on a part of the handle, or a part of the handle may be colored so that the handle has a direction indicating function. Further, it is possible to display the angle.
