Abstract

The utility model relates to a filter technical field specifically is a high fine filter of gas, which comprises a valve body, form medium inflow passageway and outflow passageway in the valve body, placed the filter core in the middle of medium inflow passageway and the outflow passageway, still be provided with the valve gap on the valve body, the valve gap passes through seal gasket and valve body and passes through double-screw bolt and nut pretension realization seal. The utility model discloses a filter element filters the impurity that carries in to the medium, ensures normal work such as protective gas distribution equipment and instrument voltage regulator, valve flowmeter, manometer, plays good filtering quality to can in time clear up filter element through opening the valve gap, avoid filtering the reduction of the medium velocity of flow that the filter element jam leads to, the practicality is higher.

Description

High fine filter of gas

Technical Field

The utility model relates to a filter technical field specifically is a high fineness filter of gas.

Background

The gas filter is widely used in the gas fields of metallurgy, chemical industry, petroleum, paper making, medicine, food, mining, electric power, city, family and the like. The gas filter is an indispensable device on a medium conveying pipeline, and is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a positioning valve or other equipment to eliminate impurities in the medium so as to protect the normal use of the valve and the equipment.

At present, a gas filter in the market has coarse filtration precision, can only be used for coarse filtration, is not suitable for fine filtration, and is easy to generate blockage after being used for a long time, so that the flow rate of a medium is reduced.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

To prior art not enough, the utility model aims to provide a high fineness filter of gas to solve the problem in the above-mentioned background art.

(II) technical scheme

In order to achieve the above purpose, the utility model provides the following technical scheme: the high-precision fuel gas filter comprises a valve body, wherein a medium inflow channel and a medium outflow channel are formed in the valve body, a filter element is placed between the medium inflow channel and the medium outflow channel, a valve cover is further arranged on the valve body, and the valve cover and the valve body are pre-tightened through a stud and a nut through a sealing gasket to realize sealing.

Optionally, the filter element is arranged in a downward inclination manner, and the bottom end of the filter element faces to a side far away from the medium inflow channel.

Optionally, the stud is fixedly connected to the valve body, the stud is located on the periphery of the bottom end of the filter element, and the sealing gasket and the end cover are both movably connected to the stud.

(III) advantageous effects

Compared with the prior art, the utility model provides a high fineness filter of gas possesses following beneficial effect: the utility model discloses a filter the impurity that the filter core carried in to the medium filters, ensures normal work such as protective gas distribution equipment and instrument voltage regulator, valve flowmeter, manometer, plays good filtering quality to can in time clear up the filter core through opening the valve gap, avoid filtering the reduction of the medium velocity of flow that the filter core blockked up and leads to, the practicality is higher.
