Embodiment

[0027] The novel bellows buffer of the present invention is mainly composed of a buffer tank body 2, a bellows 6 and a riser buffer tank cover 11 to form a buffer chamber 3; it is composed of a bellows 6, a spring 8, an upper spring seat 10 and a lower spring seat 7 The buffer elastic body is formed, and the buffer elastic body and the buffer tank cover form the gas chamber 5; the inflation valve 12 and the inflation chamber pressure gauge 13 form the inflation structure. The inflation valve 12 is mainly composed of a bonnet 121, a sealing gasket 122, a valve body 123, a valve core 124, an adjustment ring 125, a sealing ring 126 and a spring 127. Before the shock absorber is used, the gas chamber 5 is charged with a certain pressure of gas through the gas charging valve 12 . The pressure in the gas chamber 5 can be read from the inflation pressure gauge 13 . The inflation speed can be realized by adjusting the adjustment ring 125, the inflation valve 12 has a self-sealing eff...

Abstract

The invention relates to a novel buffer of a corrugated pipe, which mainly comprises a buffer tank body, a corrugated pipe elastic body and an air charging device, wherein the buffer tank body comprises a pipe connection, a buffer chamber rounded by a tank and a corrugated pipe, a cover of the buffer tank and a pressure gage in buffer chamber, the corrugated pipe elastic body comprises a lift limiter, a corrugated pipe, a spring, a spring holder, an air chamber formed by the corrugated pipe and the buffer tank cover, the air charging device comprises a charging valve, a pressure gage in air chamber. The mouthpiece of the pipe connection is connected with a lower end of the tank, the corrugated pipe elastic body is disposed at upper end of the tank with a buffer tank cover, and the air charging device and the pressure gage of the buffer chamber are disposed on the cover of the buffer tank. Comparing with prior art, the novel buffer of a corrugated pipe has the advantages of wide appliance, reliability and safety, good sealing property, convenient maintenance and the like.

Description

technical field [0001] The invention relates to a novel bellows buffer. Background technique [0002] Currently, many positive displacement pumps suffer from pressure pulsation, which prevents accurate measurement of pressure during operation. Therefore, a buffer (also called a pulse damper) must be provided at the pump outlet. Now, a rubber bag is basically installed in a tank to divide the tank into two parts, one part is directly connected with the material, and the other part is filled with a certain amount of compressed air. . This type of buffer is only suitable for occasions with low temperature, and the excessive pressure difference between the front and rear of the rubber bladder will affect the service life of the rubber bladder. [0003] Chinese patent CN 2224412Y discloses a pulse pressure buffer, which uses a buffer screw with stepped cylindrical pores at the lower end of the pressure gauge and the buffer tank, and fills a certain amount of air in the buffer t...
