Description
Technical field
The utility model relates to a kind of tapping equipment, is specifically related to a kind of exhaust discharging valve for discharges material or exhausting air.
Background technique
The exhaust that existing material pot is installed or material discharge device structural design not science, during exhaust, because tank internal pressure is higher, steam can eject from exhaust ports under the promotion of high pressure, easy scald operator, same principle, during discharge liquid material, because tank internal pressure is larger, and also non-design discharge control gear on material discharge device, cannot adjust flux, therefore high-temp liquid material can gush out from discharge gate, very easily cause security incident, and, when discharge, be vented or easy adhesion slurry on material discharge device, can freeze solidly on exhaust or material discharge device after slurry is air-dry, cannot clear up, thus reduce working life, improve cost of production.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of reasonable in design, easy to operate, long service life, and safety coefficient is high, can the exhaust discharging valve of released vapour or temperature of high temperature slurry as required.
The utility model is achieved through the following technical solutions:
A kind of exhaust discharging valve, its special way is to comprise screw rod 2, valve gap 3, valve seat 5, wherein, valve seat 5 is installed on discharge port end cap 6, the thickness direction of end cap 6 is provided with successively the conical through-hole 7 connected from bottom to top, cylindricality through hole 8, the external diameter of conical through-hole 7 is less than the internal diameter of cylindricality through hole 8, screw rod 2 is successively through valve seat 5, cylindricality through hole 8 inserts in conical through-hole 7, the conical screw plug 1 fitted tightly with conical through-hole 7 is provided with bottom screw rod 2, valve gap 3 is fixed on valve seat 5, the top of screw rod 2 is passed valve gap 3 and is spun mutually by the part body of rod and valve gap 3, the sidewall of valve gap 3 offers floss hole 4,
In order to can screw rod 2 be better fixed in end cap 6, described valve seat 5 comprises hollow column 11 and to be located at below hollow column 11 and the circular table 9 be structure as a whole with hollow column 11, the external diameter of hollow column 9 is less than the external diameter of circular table 9, the internal diameter size of hollow column 11 is identical with the internal diameter size of cylindricality through hole 8, valve seat 5 is fixed on end cap 6 by circular table 9, and valve gap 3 spins mutually with hollow column 11;
Described venting valve gap 3 cover port inwall is provided with internal thread, and the outer wall of hollow column 11 is provided with the outside thread being mated use; Venting valve gap 3 top be provided with for through screw rod 2 by mouth 10, be provided with internal thread by mouth 10 inwall, the part body of rod of screw rod 2 is provided with the outside thread being mated use.
Exhaust discharging valve structural design of the present utility model is very ingenious, when exhaust or discharge, rotate up screw rod, the conical screw plug of screw rod and conical through-hole can be separated, namely steam in material pot or liquid flow in cylindricality through hole by the gap between conical screw plug and conical through-hole, and then discharged by the floss hole on valve gap, avoid the phenomenon of steam or the material injection caused because the pressure in material pot is too high, effectively reduce potential safety hazard; Exhaust or feeding after, be rotated down screw rod, the conical screw plug of screw rod fits tightly mutually with conical through-hole, achieves the sealing of material pot.In sum, the utility model reasonable in design, long service life, easy to operate, the steam that causes because the pressure in material pot is too high or material splash can be prevented, ensure that the personal safety of operator, improve the safety coefficient of production, have a extensive future.
