Abstract
The utility model relates to the technical field of cylinders, in particular to a cylinder capable of being fine adjusted. The cylinder comprises a valve cover, a valve body and a valve core. An air inlet hole and an air outlet hole are formed on the valve body, the valve core is inserted in the valve body, the valve cover is fixed at the upper end of the valve body, a valve needle penetrates in the valve core, a valve cover through hole is formed at the upper portion of the valve cover, the upper portion of the valve core is inserted into the valve cover through hole, a valve core through hole is formed at the upper portion of the valve core, one end of the valve needle is connected with a valve needle seat, an adjusting sleeve is arranged at the upper portion of the valve needle seat, the adjusting sleeve is in threaded connection with the valve needle seat through a screw rod, a step is arranged at the lower portion of the valve core through hole, and the valve needle is clamped in the step. The height of the valve needle seat of the cylinder capable of being fine adjusted can be adjusted by rotating the screw rod, and furthermore, the height of the valve needle is adjusted. When the screw rod is rotated, the valve needle seat, the adjusting sleeve and the valve needle are lifted along with the adjusting sleeve, and the height of the valve needle also can be adjusted. Due to the fact that the screw rod is adopted for adjustment, the valve needle can be conveniently replaced.
Description
Technical field
The utility model relates to the cylinder technical field, especially relates to a kind of fine-tuning cylinder.
Background technique
At present, the needle-valve of existing plastic cement industry cast usefulness, some adopts the cylinder needle to control sealed nozzle and cast, and the cylinder needle of the type is made up of cylinder and needle, generally is that needle is fixed on the spool of cylinder.Its shortcoming is: after fixing dead needle stretched into nozzle, its distance was non-adjustable, and to the needs of needle shutoff channel size, and fixing dead needle is inconvenient to change in the time of can't satisfying cast.
The model utility content
To the deficiency that above-mentioned existing technology exists, the purpose of the utility model provides a kind of fine-tuning cylinder, and it has the position of can regulate needle in nozzle, thereby when adapting to plastic pouring, needle stretches into the characteristics of the size of nozzle bore or runner.
To achieve these goals, the technological scheme that the utility model adopted is: a kind of fine-tuning cylinder comprises valve gap, valve body and spool; Said valve body forms inlet hole and air outlet hole, and said spool is inserted in the said valve body, and said valve gap is fixed in said valve body upper end; Be equipped with needle in the said spool, said valve gap top forms the valve gap through hole, and said spool top is inserted in the said valve gap through hole; Said spool top forms valve core through hole; Said needle one end is connected with the needle seat, and the top of said needle seat is provided with adjustment sleeve, and said adjustment sleeve and said needle seat are spirally connected through screw rod; Said valve core through hole bottom is provided with step, and said needle is stuck in the said step.
Wherein, be provided with seal ring between said spool top and the said valve gap through hole.
After adopting said structure, the utility model is compared the advantage that is had with existing technology and is: the utility model comprises valve gap, valve body and spool, and said valve body forms inlet hole and air outlet hole; Said spool is inserted in the said valve body, and said valve gap is fixed in said valve body upper end, is equipped with needle in the said spool; Said valve gap top forms the valve gap through hole, and said spool top is inserted in the said valve gap through hole, and said spool top forms valve core through hole; Said needle one end is connected with the needle seat, and the top of said needle seat is provided with adjustment sleeve, and said adjustment sleeve and said needle seat are spirally connected through screw rod; Said valve core through hole bottom is provided with step; Said needle is stuck in the said step, and the utility model is the height of adjustable valve needle stand through rotating screw bolt, and then regulates the height of needle.When rotating screw bolt, needle seat, adjustment sleeve and needle go up and down along with adjustment sleeve together, can realize that also the height of needle is regulated, owing to adopt screw rod to regulate, so can be convenient to change needle.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, valve gap; 2, valve body;
3, spool; 4, air outlet hole;
5, needle; 6, valve gap through hole;
7, inlet hole; 8, valve core through hole;
9, needle seat; 10, adjustment sleeve;
11, screw rod; 12, seal ring.
Embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
As shown in Figure 1: a kind of fine-tuning cylinder, comprise valve gap 1, valve body 2 and spool 3, said valve body 2 forms inlet hole 7 and air outlet hole 4; Said spool 3 is inserted in the said valve body 2, and said valve gap 1 is fixed in said valve body 2 upper ends, is equipped with needle 5 in the said spool 3; Said valve gap 1 top forms valve gap through hole 6, and said spool 3 tops are inserted in the said valve gap through hole 6, and said spool 3 tops form valve core through hole 8; Said needle 5 one ends are connected with needle seat 9, and the top of said needle seat 9 is provided with adjustment sleeve 10, and said adjustment sleeve 10 is spirally connected through screw rod 11 with said needle seat 9; Said valve core through hole 8 bottoms are provided with step; Said needle 5 is stuck in the said step, and the utility model is the height of adjustable valve needle stand 9 through rotating screw bolt 11, and then regulates the height of needle 5.When rotating screw bolt 11, needle seat 9, adjustment sleeve 10 and needle 5 go up and down along with adjustment sleeve 10 together, can realize that also the height of needle 5 is regulated, owing to adopt screw rod 11 to regulate, so can be convenient to change needle 5.
In the present embodiment, be provided with seal ring 12 between said spool 3 tops and the said valve gap through hole 6, said seal ring mainly can play the effect of sealing, avoids gas leakage.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
