摘要： PURPOSE:To provide a diaphragm type valve which is constituted to realize retrogression of activation of a catalyst for decomposition of working fluid even when at least the temperature of the contact part surface of working fluid is comparatively low. CONSTITUTION:In a diaphragm type valve having a valve body 2 formed of a base material made of a metal and a diaphragm 3, a film layer 2A and a coating layer 3A, which are formed of a material having a catalyst active order for a decomposition action for working fluid being subordinate compared with at least a base material, are formed on the outermost surfaces of the valve body 2 and the diaphragm 3. Since the film layer and the coating layer the catalyst active order of which is subordinate compared with the base material are formed, in a case working fluid, such as silane gas, is brought into contact, decomposition reaction of silane gas sufficiently retrogresses compared with a case the film layer and the coating layer are not formed.

摘要： PURPOSE:To provide the pressure reducing valve which can perform remote control over setting variation in reference pressure and the cutting of a flow passage and restore its cutting function even if power for the remote control is spoiled. CONSTITUTION:The self-actuated pressure reducing valve which has an auxiliary driving part 20 for giving mutually reciprocal axial thrusts to a valve shaft 11 and a cutoff spring 27 is equipped with a handle 36 which varies and sets the compression quantity of the cutoff spring 27. Therefore, when a remote control power source for reference pressure is removed, the cutoff spring 27 closes the valve 12, but even if the power source is lost, the pressure reducing function is restored with the handle 36.

摘要： PURPOSE:To make compatible securing of required minimum pressure to let out carbon ated drink well and controlling of appropriate gas pressure in response to the tempera ture of the drink by controlling a valve body to open or close according to the output of a sensor part when the temperature in a drink tank is at a specified temperature or more while by securing a specified flow pressure when the temp. is at the specified level or less. CONSTITUTION:There is provided main valve body 20a to open or close a flow passage 12a of carbon dioxide gas to be communicated with a carbon dioxide gas supply part at its inlet side while with a drink tank at its outlet side. There is also provided a means for opening or closing this body 20a so that it has a specified flow out pres sure when the temp. in the drink tank is at a specified level or less, and a means for opening or closing the body 20a according to the output of a sensor part 41 when the temperature is at the specified level or more. With this arrangement, the opening of the body 20a is controlled by the output from the sensor part 41 in response to the temperature in the tank so that pressure of carbon dioxide is applied properly at all times to carbonated drink. The opening is also controlled to secxure a required minimum pressure when the temperature becomes a low level below the required minimum pressure.

摘要： PURPOSE:To protect a handle from being brought into contact with other matter by inserting the handle removably in the axial direction into the input section of a drive screw member while providing a restricting means of an anti-removal chip for the handle together with an intermediate transmission tool. CONSTITUTION:A handle 7 of a stop valve 5 is fastened through rotation so as to screw a drive screw member 25 against a valve box 9. The handle 7 is inserted rollably and removably in the axial direction into an input section 25a of the drive screw member 25 while a spring S and an intermediate transmission tool 26 are arranged in a valve close thrust transmission system T. A restricting means 35 of an anti-removal chip 29 for the handle 7 is provided across the drive screw member 25 and the intermediate transmission tool 26. Since the handle can be removed under closed condition of the stop valve, it is protected from being brought into contact with other matter.

摘要： PURPOSE:To improve durability, by forming a valve shaft supporting member and a valve body, opening and closing a valve hole and supported to a valve shaft, from a ceramic material while coating the valve shaft with a ceramic material. CONSTITUTION:A valve forms its main unit 1 forming a flow path 3, supporting member 5 rotatably supporting a valve shaft 6 and connecting with the main unit 1 and a valve body 7 all from a ceramic material. While the valve shaft 6 is coated with a ceramics made cylindrical part 12, 13 and the valve body 7. Accordingly, the valve, forming by ceramics all of the parts brought into contact with fluid, is excellent in wearing resistance, corrosion resistance, etc. While the valve shaft 6 may be formed by a metallic material, and the valve, being able to sufficiently resist driving force when the valve is operated, can be surely opened and closed.

摘要： PURPOSE:To improve the sealing performance by forming a plurality of recesses which have a depth greater than the dig-in depth when being pressed on a pressure surface of a metal plate having an opening corresponding to an intended space of sealing. CONSTITUTION:A gasket 20 to seal passages 12, 13 forming a space to be sealed comprises a metal plate, and its pressure surface has multiple depressions 22. The depth H of the depression 20 is formed in such a manner that it is adequately deeper than the dig-in amount (h) of flanges 14, 15 into the depression 22 when pressed by the flanges 14, 15. Since there is no connecting space between the depressions 22 in a radial direction of the gasket 20, the fluid in the passage 12, 13 will not leak outside, and the sealing performance is significantly improved.
