摘要： An apparatus for damping the pulsation of a reciprocating pump which occurs due to variation of a flow rate and a pressure of a fluid ascribed to the reciprocation of the pump. The apparatus can be installed and used in either a vertically set state or a horizontally set state by improving an exhaust valve mechanism, and manufactured to a simple structure at a low cost with maintenance work for a supply and exhaust valve rendered easy. The apparatus comprises an apparatus body-forming casing (17) in which a liquid chamber (20a) temporarily storing a transfer liquid from a pump, and an air chamber (20b) are isolated from each other by an expansible pulsation restraining diaphragm (18), an opening (27) provided in this casing so as to communicate with the air chamber, a valve case (23) detachably fitted in this opening, a closing spring (49) interposed between an exhaust valve disc (43) and a spring seat (47) which are mounted on an exhaust valve stem (45), and an opening spring (50) interposed between the spring seat and a slider (48).

摘要： According to the present invention, a device body casing 17 has a liquid chamber 20a for temporarily storing a liquid to be transported by a pump, a gas chamber 20b, and an extendably and contractibly deformable pulsation suppression diaphragm 18, which separate them. The device body casing 17 having an aperture 27 so as to communicate with 20b, is detachably engaged with a valve case 23. The valve case 23 is provided with an automatic gas supply valve mechanism 33 and an automatic gas exhaust valve mechanism 34, which restrict the amount of the extendable and contractible deformation of the pulsation suppression diaphragm 18 within the predetermined range, so that a liquid pressure inside the liquid chamber 20a and an atmospheric pressure inside the gas chamber 20b may balance each other when the discharge pressure of the pump is fluctuated. The automatic gas exhaust valve mechanism 34 is provided with a gas exhaust port 32, a gas exhaust valve element 43, and a slider 48. The gas exhaust port 32 exhausts the gas from the gas chamber 20b to the outside, when the gas sealing pressure inside the gas chamber 20b is decreased. The gas exhaust valve element 43 usually makes the gas exhaust port 32 close. The slider 48 is operated so that the gas exhaust valve element 43 may usually make the gas exhaust port 32 open, when the pulsation suppression diaphragm 18 is moved in a direction of reducing the liquid chamber 20a so as to exceed the predetermined stroke. The gas exhaust valve element 43 is disposed on a tip of the gas exhaust valve rod 45. A rear end of the gas exhaust valve rod 45 is slidably inserted in the slider 48. The gas exhaust valve rod 45 is loosely inserted in a through hole 46 of the spring receiving member 47 fixed to the inside of the gas exhaust chamber 42 of the valve case 23. On the gas exhaust rod 45, a spring 49 for a closing state is disposed between the gas exhaust valve element 43 and the spring receiving member 47, and a spring 50 for an opening state is disposed between the spring receiving member 47 and the slider 48.

摘要： It is an object of the invention to, even in the case where transported liquid containing a sedimenting material such as slurry is used, prevent the sedimenting material from stagnating and collecting in an extending and contracting portion of a bellows. In order to attain the object, a bellows 7 that is extendingly and contractingly deformable in the axial direction is placed in a pump body 1 with setting the axis B of the bellows vertical so as to be driven to perform extending and contracting deformation, and form a liquid chamber 9 inside the bellows 7. A suction port 18 and a discharge port 19 are formed in an inner bottom face 4a of the pump body 1 facing the liquid chamber 9. Liquid is sucked from the suction port 18 into the liquid chamber 9 by extension of the bellows 7, and the liquid in the liquid chamber 9 is discharged from the discharge port 1 by contraction of the bellows 7. The extending and contracting portion of the bellows 7 which is configured by forming ridge-like folds 71 and valley-like folds 72 in a vertically alternate and continuous manner is formed into a shape in which the lower one of upper and lower lamella portions 71a and 71b of each of the ridge-like folds 71, or the lower lamella portion 71b is downward inclined as moving toward the axis B, not only in an extending state but also in a contracting state. Even in the case where liquid containing a sedimenting material such as slurry is used, therefore, the sedimenting material can be prevented from sedimenting and stagnating in the extending and contracting portion of the bellows 7.
