Description

Guide ceramic valve rod for filling valve and filling valve thereof

Technical Field

The utility model belongs to the technical field of the filling valve, especially, relate to a filling valve is with direction ceramic valve rod and a filling valve who uses direction ceramic valve rod.

Background

The filling valve is a device for filling beverage, after a material channel is opened, the material in a material cylinder enters a bottle under the action of gravity, and meanwhile, residual air in the bottle is discharged out of the bottle from an exhaust pipe; when the material liquid level reaches the bottom end of the lower exhaust pipe, the exhaust passage is closed, so that the filling is finished, and the liquid level is basically stable.

The Chinese authorization (CN201694815U) discloses a filling valve, which comprises a valve seat 12 communicated with a material cylinder 15, wherein a vertical material channel 16 is arranged in the valve seat 12, a valve port 5 is arranged below the material channel, a valve head 4 is fixedly arranged in the material channel, a lower exhaust pipe 14 penetrates through the valve head, an upper exhaust pipe 13 penetrates through the upper part of the valve seat 12, the upper exhaust pipe is communicated with the lower exhaust pipe, the upper end of the upper exhaust pipe extends out of the liquid level of the material cylinder 15, the lower exhaust pipe extends into a bottle, a sliding sleeve 8 is slidably arranged on the inner wall of the material channel, a spring 9 is arranged between the sliding sleeve 8 and the valve seat 12 in a padding mode, a sealing gasket 7 is fixedly arranged at the bottom of the valve head and the sliding sleeve in a conical surface matching mode; install horizontal valve rod cover 10 in the disk seat, slidable mounting has valve rod 11 in the valve rod cover, and the front end of valve rod 11 has sealing washer 2, and negative pressure passageway 17 and the sealed cooperation of sealing washer 2 have been seted up to the disk seat in valve rod the place ahead, is provided with return spring 1 between the front end of valve rod and the disk seat, and cam layering 18 has been put to the rear end pressure.

The valve rod of the filling valve is a stainless steel valve core, the existing stainless steel valve core is connected with the valve sleeve through a sealing ring, and the end part of the stainless steel valve core is also connected with a cam pressing strip through a guide strip. Under the condition of high temperature and small quantity, the sealing ring of the filling valve is easy to age, expand and resist to be increased and corroded by materials; the guide between the valve rod and the valve sleeve is not flexible, and the channel cannot be closed due to the fact that the spring cannot reset; secondly, the guide belt and the sealing ring need to be replaced regularly.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a filling valve is with direction ceramic valve rod adopts and sets up ceramic coating in the stainless steel case outside, and high temperature resistant is not afraid of to corrode, and ceramic valve rod adopts the cooperation direction with the valve barrel to seal, cancels guidance tape, sealing washer, avoids the problem that direction inflexibility, spring can not reset between the ageing valve rod valve barrel that brings of sealing washer.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a filling valve is with direction ceramic valve rod, ceramic valve rod includes stainless steel valve core and sets up the ceramic coating in the stainless steel valve core outside, ceramic valve rod adopts the cooperation direction to seal with the valve barrel.

A guide ceramic valve rod for a filling valve is mainly applied to a filling machine on a liquid beverage packaging production line and used for controlling a filling valve channel on the filling machine.

A filling valve comprising the above-described pilot ceramic valve stem.

The utility model discloses following beneficial effect has:

the utility model adopts the ceramic coating arranged outside the stainless steel valve core, which is high temperature resistant and corrosion resistant, the ceramic valve rod and the valve sleeve are sealed in a matching guide way, a guide belt and a sealing ring are cancelled, the ceramic finish degree is high and the stainless steel hardness is different, and the ceramic valve rod and the valve sleeve can not be occluded, so the guide sealing between the ceramic valve rod and the valve sleeve is very good; the ceramic valve rod can effectively avoid the influence caused by high-temperature aging and corrosion of the sealing element.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
