Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
in an embodiment, as shown in fig. 1, a leakage-proof corrosion-resistant four-way valve seal head comprises a seal head body 1 and a protective sleeve 2, wherein the protective sleeve 2 is cylindrical, a body cavity 21 with an open lower side and a buffer cavity 22 with an open upper side are formed in the protective sleeve 2, the seal head body 1 is inserted and fixed in the body cavity 21, a threaded hole 11 with an open lower side is formed in the seal head body 1, a sinking platform 12 is formed on the outer edge of the lower end of the seal head body 1, and a sealing ring 3 is sleeved in a groove formed by the sinking platform 12 and the body cavity 21; a cushion block 4 is arranged in the cushion cavity 22.
Furthermore, a round boss 23 is formed in the middle of the buffer cavity 22, a disk spring 5 is sleeved on the round boss 23, and the disk spring 5 is clamped between the bottom surface of the buffer cavity 22 and the lower end surface of the buffer cushion block 4;
the middle part of the cushion pad 4 is formed with a step through hole 41, the small end hole of the step through hole 41 is in clearance fit with the circular boss 23, the step surface of the step through hole 41 is pressed against the shaft retainer ring 6 positioned on the upper side of the step through hole, and the shaft retainer ring 6 is inserted and sleeved on the circular boss 23. When the core iron of the four-way valve is close to the end enclosure, the core iron is firstly contacted with the cushion pad 4, and after the cushion pad is pressed, the disc spring deforms to continue accumulating elastic potential energy, so that a buffering effect is achieved.
Furthermore, the upper end face of the cushion pad 4 is higher than the upper end face of the circular boss 23 and the upper end face of the protective sleeve 2, so that the core iron is not contacted with the protective sleeve firstly when being close to the end socket.
Furthermore, at least two, two or more than two disc springs 5 are arranged in an overlapping manner.
Furthermore, a bolt through hole 13 is formed on the bottom surface of the threaded hole 11; a threaded counter bore 24 corresponding to the bolt through hole 13 is formed on the bottom surface of the body cavity 21;
the bolt through hole 13 is internally sleeved with a screw 7, and the screw 7 is screwed on the threaded counter bore 24.
Furthermore, the threaded counter bore 24 and the central axis of the protective sleeve 2 are eccentrically arranged, so that the screw 7 can be effectively loosened in the sealing head installation process.
Furthermore, the round boss 23 is formed with a disassembly assisting threaded through hole 25, when the end socket body 1 needs to be disassembled from the protective sleeve 2, the disassembly assisting threaded through hole 25 can be screwed with a long screw, and the end socket body 1 can be ejected out by rotating the long screw.
Finally, the above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
