Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 2, a pulse damper structure comprises a housing 1 and an air bag 5, wherein the housing 1 comprises a sleeve 2, a top cover 3 and a tail cover 4 which are respectively arranged at two ends of the sleeve 2, the sleeve 2 is cylindrical, two ends of the sleeve 2 form a mounting port 21, the top cover 3 and the tail cover 4 are respectively fixed at two ends of the sleeve 2 in a sleeved manner, an air inlet 31 is arranged on the top cover 3, a liquid inlet 46 is arranged on the tail cover 4, a baffle 6 is coaxially embedded in the sleeve 2, and a plurality of water through holes 61 are arranged on the baffle 6;

firstly, an air bag 5 is placed into a sleeve 2 from an installation opening 21, an inflation valve is arranged on the air bag 5 and penetrates through an air inlet 31 on a top cover 3, then a baffle 6 is embedded into the sleeve 2, a tail cover 4 is sleeved at the other end of the sleeve 2, and waterproof viscose glue is coated at two ends of the sleeve 2, so that the shell 1 is completely fixed; when the water pressure outside the air bag 5 is lower, the baffle 6 blocks the expansion range of the air bag 5, the air bag 5 is prevented from extending out of the liquid inlet 46, the purpose of protecting the air bag 5 is achieved, and when the water pressure is high, the water through holes 61 in the baffle 6 can enable water to pass through, meanwhile, the larger impurities in the water are prevented from entering the shell 1 to cause damage to the air bag 5, and the purpose of protecting the air bag 5 is further achieved.

Wherein at baffle 6 towards the coaxial basin 62 of having seted up in one side of casing 1, limbers 61 all communicates with basin 62, and basin 62 communicates with inlet 46, and when water flowed in casing 1, liquid passes through inlet 46 and gets into in the basin 62, again from the basin 62 through the smooth flow of limbers 61 to the casing 1 in, promote the smooth and easy nature of the flow of water.

The second embodiment is different from the first embodiment in that:

as shown in fig. 3, the tail cover 4 includes a ring body 41 and a tail plate 42, the ring body 41 is in threaded connection with the outer side of the sleeve 2, a liquid inlet hole is formed in the tail plate 42, a sealing ring 43 is embedded in the ring body 41, when the ring body 41 is fixed to the outer side of the sleeve 2 in a rotating manner, the sealing ring 43 is squeezed between the enclosing plate and the sleeve 2, the sealing ring 43 seals water flow, the tail cover 4 is detachably fixed, and the air bag 5 in the tail cover is convenient to replace; and one side of the tail plate 42 facing the shell 1 is provided with a conical surface 421, so that a larger space can be reserved between the baffle plate 6 and the tail plate 42, water flow can smoothly enter the space between the tail plate 42 and the baffle plate 6, the tail plate 42 is prevented from sealing the water through hole 61, and the water inlet fluency is improved.

Wherein, a baffle ring coaxially extends from one side of the tail plate 42 facing the shell 1, a sealing ring 43 is embedded between the baffle ring and the ring body 41 to limit the position of the sealing ring 43, so that the sealing ring 43 can be stably abutted with the sleeve 2 to ensure the sealing stability, a pressing ring 44 is coaxially embedded between the baffle ring and the ring body 41, the pressing ring 44 is abutted against one end of the sealing ring 43 departing from the sleeve 2, meanwhile, bolts 45 are connected to one end of the tail, which is far away from the sleeve 2, at intervals in the circumferential direction through threads, one end of each thread is abutted against the pressing ring 44, since the casing 1 is usually made of plastic material, when the temperature changes, the thread fit between the tail cap 4 and the sleeve 2 becomes loose, causing the abutting between the seal ring 43 and the sleeve 2 to become loose, through rotating bolt 45, bolt 45 promotes clamping ring 44, and clamping ring 44 further extrudes sealing washer 43 and sleeve 2 butt, and then guarantees sealed stability.
