Abstract
The utility model relates to an ejector pin vertical-type automatic exhaust valve. An exhaust nozzle is fixed on a valve seat, the valve seat is internally provided with a chute communicated with the exhaust nozzle, the upper end of the chute is a valve port, and the upper end of an ejector pin arranged on a floating ball inside a casing is located within the chute. The ejector pin vertical-type automatic exhaust valve is characterized in that the lower end of the valve seat is provided with ring grooves, the upper end and the lower end of a filter screen or a slit-type filter device are snapped in the two ring grooves. The filter device is disposed at the chute port in the structure of the utility model, in case of the valve body without water, the floating ball falls down, slits of the filter device open, and the gas is discharged from the exhaust nozzle via the valve port. In case of the valve body with water, the floating ball ascends to close the slits of the filter device, and then impurities are retained out of the chute, thereby effectively preventing the impurities from entering the chute.
Description
Technical field
The utility model belongs to the heating system automatic exhaust valve.
Background technique
The vertical automatic exhaust valve of thimble comprises upper and lower casing, and valve seat is fixed on the upper shell, fixing steam discharge mouth on the valve seat, a slideway that is communicated with the steam discharge mouth is arranged in the valve seat, the slideway upper end is a valve port, and the thimble on the housing inner float ball is in slideway, and valve port is opened or sealed to the thimble head under the drive of ball float.Owing between slideway and the thimble slit is arranged, so the impurity in the water can enter into from the slit in the slideway, piles up at the valve port place, causes thimble head and valve port bad sealing, makes valve invalidation.
Summary of the invention
The purpose of this utility model is to provide a kind of impurity that can prevent to enter the vertical automatic exhaust valve of valve port thimble, the technical solution of the utility model as shown in Figure 1, comprise, lower shell body, a valve seat is fixed on the upper shell, fixing steam discharge mouth on the valve seat, a slideway that is communicated with the steam discharge mouth is arranged in the valve seat, the slideway upper end is a valve port, be fixed with sealing gasket on the valve port, thimble upper end on the housing inner float ball is in slideway, it is characterized in that an annular groove being arranged, an annular groove is arranged on thimble, on filter screen or the chink type filtrating equipment in the lower end of valve seat, the lower end is stuck in two annular grooves.This structure is provided with a filtrating equipment at the slideway mouth, and when in the valve body when anhydrous, ball float falls, and drives the filtrating equipment hole and opens, and gas is discharged from exhaust nozzle through valve port; Float rises when in the valve body water being arranged, and drives the closing of pores of filtrating equipment, and impurity is blocked in outside the slideway, has prevented that effectively impurity from entering slideway.
The utility model has overcome the filtration difficult problem at thimble active state glide path, does not influence the space layout of valve body, and is simple in structure, economical and practical, solved the Problem of Failure of leaking that is deposited in the vertical automatic exhaust valve of thimble that valve port produces owing to impurity effectively.
