で、此のバルブ一個で微調整まで可能である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention internally mounts a shell type sliding valve head capable of rectifying irrespective of the kind of fluid, without causing turbulent flow and vibration in the flow in the valve pipe. The normal valve has a fluid resistance that is reduced as much as possible, and by turning the adjusting ring from outside the pipe, the valve can be opened and closed.Unlike conventional valves, this valve has an external handle and handle. There is no protrusion like that, and the outside of the valve is an adjustment ring, and the vernier scale engraved on the adjustment ring and cylinder allows the opening of the valve to be read exactly in accordance with the scale. Therefore, if not only the reproducibility of the flow rate but also the pressure immediately before the valve is known, if the relationship between the opening and the flow rate is created in advance as a table, that flow rate can be read on the vernier scale without using a flow meter. Can be found at. Further, since the scale can be set to be a minute scale, it is possible to make a fine adjustment with this one valve.

て製造上有利である。In a piping system, if the flow rate is throttled by a valve, the pressure in the piping in front of the valve rises. Therefore, a relief valve is required at a place where the pressure needs to be made constant or in a pressure piping system which is desired to be placed within a safe pressure. This device has extremely low resistance in the pipe of the fluid, and the relief pressure can be set easily and accurately outside the pipe. Further, in the manufacturing, having the same structure as the flow rate adjusting valve can reduce the manufacturing cost, which is advantageous in manufacturing.

When the valve seat or valve or valve is opened, the flow direction is greatly changed during the throttling process of the valve, causing a large vortex flow behind the valve, increasing the valve resistance, and in-pipe equipment after the valve. On the other hand, it is difficult to judge the flow rate from the position of the handle that has various adverse effects and adjusts the flow rate, or the reproducibility of the flow rate cannot be said to be easy. You must use a valve for fine adjustment using the circuit. It is difficult to open the circuit and make fine adjustments with a single valve.

In the pressure regulating valve, the pipes are mounted in parallel from the position of the pressure inlet and the outlet on the mounting means.
In the present situation, it is impossible to adjust the pressure setting from the outside of the pipe in a valve having a straight flow or being bent at an angle of 0 °. Therefore, the mounting pipe is also complicated.

出来るだけ整流化し管内抵抗を減少させる必要がある。As described in detail in the section of the prior art, the fact that the flow rate and pressure can be set accurately from outside the pipe without changing the flow direction of the fluid is This is an important issue along with reducing the resistance in the tube. Furthermore, the flow in the pipe usually flows with spiral vortices,
It is necessary to rectify as much as possible to reduce the resistance inside the tube.

る事が出来る。A cylinder 2 is formed by cutting a precision screw portion 12 on the outer side of one end with a cylindrical tube, and a valve seat 3 having a pipe mounting screw 14 on the other end via a packing 13. Since the leakage prevention and the shell type sliding valve head can be installed inside the cylinder, the internal screw is easy to disassemble.
The shell-shaped valve head 4, the support wing 11 and the sliding pipe 30 are integrated on the inner surface cut in this way, and it has sufficient rigidity so that the valve seat and the valve head can be closely adhered to each other easily. The structure is provided with a margin L that can reciprocate on the inner surface of the cylinder. In this way, the fluid passing through the valve seat follows the streamline of the shell type valve head,
It is rectified by the support wing 11 through the arrow 17 and the arrow 29
To move to the next piping system, in order to move this shell type sliding valve head with the outer adjusting ring 1, the cylinder has a long hole 20,
There is an integer number, and there is a screw 24 in the sliding tube 30 of the shell type sliding valve head corresponding to this, and the sliding piece 8 is inserted from the outside of the cylinder 2 and fixed with the mounting bolts 10. The head is movable in only the longitudinal direction with respect to the cylinder, and there are two O-rings 16 on the inner surface of the cylinder. The shell type sliding valve head and the cylinder are completely sealed and there is no leakage. The adjusting ring 1 is such that the guide ring 7 divided into the inner surface is housed in the sliding groove 18 and then inserted from the precision screw 12 side of the cylinder to engage the screws with each other, and the hole 19 in the knob portion of the adjusting ring 1 is inserted. Using the above, the bolt is attached to the screw hole 22 of the sliding piece, and the knob portion of the adjusting ring 1 is turned by such a means, so that the graduation 26 on the cylinder becomes 0 point. By turning the adjusting ring until the zero point of the scale marked on the end of the adjusting ring is aligned, the valve head comes into close contact with the valve seat and shuts off the flow of fluid. From here, the valve is tightened in the opening direction. By turning the knob 28 in the opposite direction to the time, it is possible to obtain a precise valve opening for each scale on the scale engraved on the adjusting ring.

バルブをレリーフバルブとすることが出来る。The relief valve must be a valve capable of precise set pressure when the pressure in the pipe is required to be safe for the equipment of the pipe system or a constant design pressure is always required. In addition, a spring force capable of setting a desired pressure must be applied to the valve head so as to correspond to the pre-valve pressure. Therefore, in the case of the present invention, the valve head of the shell type sliding valve head is divided into A spring chamber is provided and a predetermined spring is installed therein, whereby the adjustment ring 1 adjusts the expansion and contraction of the spring and sets the required pressure, that is, the contact pressure between the valve seat and the valve head is set to the outside. By using the vernier scale and the pressure setting scale, the flow rate adjustment valve can be used as a relief valve.

By precisely reciprocating the shell-type sliding valve head through the groove, guide ring and sliding piece, the opening between the valve seat and valve head can be adjusted by the vernier scale engraved on the adjustment ring and cylinder. , The amount of movement is arranged so that it can be read accurately in accordance with the opening of the valve, and without diverting the flow of the fluid in the pipe, along the streamline of the shell type valve head, it is rectified by the supporting vanes and Invention of a flow rate control valve that allows passage of water.

置。2. A vernier scale using an adjusting ring and a cylinder, wherein the shell-type sliding valve head has a shell-shaped valve head that is divided from the crown and a spring is installed inside the shell to form the valve head. The relief valve device allows the relief pressure of the relief valve to be freely set from outside the pipe by turning the adjustment ring.
