Abstract
The invention discloses a spring-type breather valve, which is characterized in that: a valve seat is connected with a shell through a tightening bolt, the valve seat is provided with a vent hole, a valve sleeve is nested inside the valve seat, a valve sleeve sealing ring is arranged between the contact surface of the valve seat and the valve sleeve, the side wall of the valve sleeve is provided with an air outlet hole, the top surface of the valve sleeve is provided with an air inlet hole, one end of the valve sleeve spring is pressed on the outer side surface of the top surface of the valve sleeve, the other end of the valve sleeve spring is pressed on an adjusting plate on the inner top surface of the shell, and the adjusting plate is fixed through an adjusting bolt on the top part of the shell; a reversed T-shaped valve rod passes through the top surface of the valve sleeve, one end of a valve rod spring is pressed against the outer side surface of the top surface of the valve sleeve, the other end of the valve rod spring is pressed against a fixed plate on the top end of a valve rod, and a valve rod sealing ring is arranged between the contact surface of a transverse plate of the reversed T-shaped valve rod and the inner side surface of the top surface of the valve sleeve. The spring-type breather valve is installed on a closed tank, when the air pressure of the closed tank is increased, air pushes upwards the valve sleeve, and the air inside the tank is released through the vent hole on the valve seat via the air outlet hole on the side wall of the valve sleeve; during the unloading process, negative pressure is formed inside the closed tank, external air enters the closed tank through the vent hole on the valve seat and pushes the valve rod downwards via the air inlet hole on the top surface of the valve sleeve, so materials can be ensured to discharge from the closed tank; and by adjusting the elastic force of the spring, a certain pressure difference can be realized inside the closed tank so as to satisfy the production requirement.
Description
Technical field
The present invention relates to a kind of inhalation valve.
Background technique
Present employed vapor tight tank, like fermenting tub, in use, because a jar interior material produces gas; Cause jar internal pressure to increase, influence the fermentation of material, even cause tank body to damage, and when discharging; Owing to there is not air to get into, in the tank body, form negative pressure, cause discharging not to the utmost; And also there is the discontented and discharging problem not to the utmost of charging in jar storage tank owing to there is gas to exist in the jar.
Summary of the invention
The purpose of this invention is to provide the inhalation valve that uses on a kind of vapor tight tank.
Technological scheme of the present invention is, a kind of spring inhalation valve, and valve seat is connected through clamping bolt with housing; Have vent on the valve seat, in valve seat, be with valve pocket, valve seat and the valve pocket surface of contact between be provided with the valve pocket seal ring; On sleeve side wall, have air outlet hole, on the valve pocket end face, have inlet hole, an end of valve pocket spring is pressed on the end face outer side surface of valve pocket; The other end is pressed on the regulator plate of housing inner top surface, and regulator plate is through the adjusting bolt of case top; " ⊥ " shape valve rod passes the end face of valve pocket, and an end of valve rod spring is pressed on the end face outer side surface of valve pocket, and the other end is pressed on the fixed plate of shell masthead end, between the surface of contact of the inside top surface face of the transverse slat of " ⊥ " shape valve rod and valve pocket, is provided with valve stem packing ring.
The present invention is contained on the vapor tight tank, when vapor tight tank air pressure increases, and the gas jack-up valve pocket that makes progress, gas releases from the vent on the valve seat through the air outlet hole on the sleeve side wall in jar; When discharging, vapor tight tank forms negative pressure, and ambient atmosphere gets into from the vent on the valve seat, and the inlet hole on the valve pocket end face is pushed valve rod downwards open, enters in the vapor tight tank, guarantees that a jar interior material draws off from vapor tight tank; Through adjustment spring force size, can make has certain pressure difference in the jar, meet the needs of production.
