Embodiment 1

[0028] Refer to attached Figure 1-2 As shown, a reliable and anti-loose one-way isolation valve structure, the one-way isolation valve includes a support sleeve 1 , a valve core 2 , a spring 3 and a valve seat 4 .

[0029] The support sleeve 1 is provided with a cavity 5 inside, and the cavity 5 is located at the left end of the support sleeve 1 and has an opening. The cross-sectional shape of the opening is stepped. Due to the stepped structure, the diameter of the opening gradually decreases from the outside of the cavity 5 to the inside of the cavity 5 . There is an internal thread 6 at the position with the largest opening diameter, and the shape of the right end of the valve seat 4 matches the shape of the opening. The right end of the valve seat 4 includes a wider part 7 and a narrower part 8, where the wider part 7 and the narrower part 8 For relative description, that is, the width dimension of the wider portion 7 is larger than that of the narrower portion 8 . The ...

Embodiment 2

[0035] see image 3 As shown, a booster cylinder structure includes a cylinder body 12, a ram base 13, a ram 14, a support 15, a guide sleeve II 16, a guide sleeve I 17 and the one-way isolation valve structure described in Embodiment 1.

[0036] The cylinder body 12 is hollow and has openings at both ends.

[0037] The ejector rod seat 13 is located near the opening of the left end of the cylinder body 12 , and partly protrudes into the cylinder body 12 , and the protruding part is connected with the left end of the ejector rod 14 . The right end of push rod 14 passes through support 15, and valve seat 4 is connected with valve core 2.

[0038] The guide sleeve II16 is located in the cylinder body 12 and sleeved on the valve seat 4 , and the support 15 is located between the guide sleeve II16 and the ejector rod seat 13 .

[0039] The guide sleeve I17 is located near the opening of the right end of the cylinder body 12 and partly extends into the cylinder body 12 . The gui...

Abstract

The invention discloses a reliable and anti-loose one-way isolating valve structure and a pressure cylinder structure. The reliable and anti-loose one-way isolating valve structure comprises a supporting sleeve and a valve seat, a cavity is formed in the supporting sleeve, an opening is formed in the position, located at one end of the supporting sleeve, of the cavity, and a part of the valve seatstretches into the opening and is in threaded connection with the supporting sleeve. The reliable and anti-loose one-way isolating valve structure further comprises a locking pin penetrating the supporting sleeve in the radial direction of the supporting sleeve, a part of the locking pin penetrates into the valve seat, and the locking pin is in interference fit with the supporting sleeve. The pressure cylinder structure comprises a cylinder body, an ejector rod base, an ejector rod, a support, a guide sleeve II, a guide sleeve I and the reliable and anti-loose one-way isolating valve structure, wherein a part of the ejector rod base is arranged in the cylinder body, the ejector rod is arranged in the cylinder body, the support is arranged in the cylinder body, the guide sleeve II is arranged in the cylinder body, and a part of the guide sleeve I is arranged in the cylinder body. The reliable and anti-loose one-way isolating valve structure and the pressure cylinder structure have thebeneficial effects of being good in anti-loose effect, perpetually anti-loose and the like.

Description

technical field [0001] The invention relates to a reliable anti-loosening one-way isolation valve structure and a booster cylinder structure. Background technique [0002] At present, the supercharging of some large die-casting machines usually adopts the floating piston supercharging structure. The supercharging structure includes the cylinder wall and the one-way isolation valve set in the cylinder wall. Therefore, the stability of the one-way isolation valve as an important part directly affects the increase. Effect. The existing one-way isolation valve includes a support sleeve, a valve seat and a valve core. The support sleeve is provided with a cavity inside, and the valve core is located in the cavity. One end of the support sleeve is provided with an opening, and the opening is provided with an internal thread. An external thread is provided on the outer surface of a part, and this part of the valve seat extends into the opening to form a thread fit with the interna...
