The utility model adopts the technical proposal that: the utility model provides a ball valve of removable spring, includes the valve body to and locate the connecting pipe of valve body both sides, the top of valve body is equipped with the valve gap, but be equipped with swivelling joint's valve rod on the valve gap, the one end of valve rod is equipped with the valve ball, is equipped with sliding connection's sealing ring between valve ball and the connecting pipe, and is equipped with the spring between sealing ring and the connecting pipe, the outside of connecting pipe is equipped with the clamping ring, the one end and the sealing ring of spring are connected, and the other end is connected with the clamping ring, be equipped with the seal block on the clamping ring.
Further, be equipped with on the connecting pipe with clamping ring assorted mounting groove, be equipped with the through-hole on the mounting groove, the clamping ring passes through the mounting groove to be connected with the connecting pipe, the spring passes through the through-hole and locates between clamping ring and the sealing ring.
Furthermore, a threaded hole is formed in the mounting groove, and the pressing ring is connected with the connecting pipe in a threaded connection mode through the threaded hole.
Furthermore, the compression ring is in a semicircular ring shape, and the sealing block is sleeved on the compression ring.
Furthermore, the inner side surface of the mounting groove and the outer side surface of the sealing block are inclined surfaces.
Furthermore, a rubber ring is arranged on the outer side surface of the sealing ring, which is in contact with the valve body.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the replacement of the spring is facilitated through the detachable compression ring, the situation that the spring cannot reach the pressure required by the sealing ring due to metal fatigue is avoided, and therefore the sealing performance of the ball valve is improved.
2. The liquid medium in the valve body is prevented from leaking from the mounting groove through the sealing block between the pressing ring and the valve body, and the sealing performance of the ball valve is improved.
3. The compression ring and the mounting groove are both in a semicircular ring shape, so that the compression ring is simple and convenient to disassemble and assemble.
The embodiments of the present invention will be further explained with reference to the drawings.
