Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of good manual relief valve of sealing, should
Manual relief valve includes valve body 6, and valve body 6 is：The structure being made up of valve core housing 1, valve seat 2, valve rod 3, connecting rod 4 and spring 5；
Connecting rod 4 is located inside valve body 6, and the upper end of connecting rod 4 is threadedly coupled with a control handwheel 7, and the outer wall of connecting rod 4 is provided with footstock
8, through spring 5 is provided with, spring 5 is socketed on the outer wall of connecting rod 4, valve element at the middle part of the lower end of footstock 8 and the upper end of valve core housing 1
The underface of set 1 is provided with valve seat 2, and the bottom of connecting rod 4 is provided with valve rod 3, and valve rod 3 is inserted inside valve core housing 1, valve seat 2 and valve
A spring system 9 is provided with inside the forward surface of core retainer plate 1, the interior outer oil seal spring 12 including outer ring of spring system 9 is interior with inner ring
Oil seal spring 13, it is connected with each other between inner oil seal spring 13 and outer oil seal spring 12 by extension spring 15, the left end of valve body 6 is import
18, the right-hand member of valve body 6 is outlet 17.
Further, the contact position of valve rod 3 and valve core housing 1, is inlaid with a 5.0mm steel balls 10 in the bottom of valve rod 3, utilizes ball
The finish in face can more effectively reduce the friction and wear of valve rod 3 and valve core housing 1 with abrasion resistance, so as to pass through valve rod 3
Freely to adjust the cooperation position between the sealed bottom face of valve rod 3 and the inner sealing face of valve core housing 1, reach reliable sealing and match somebody with somebody
Close；
