Abstract
The utility model discloses a horizontal full automatic exhaust valve, comprising a shell, a valve seat and an air vent, wherein the shell includes an upper body and lower body, besides the valve seat in the upper body is fixed by the bolt. One side of pull rod is connected with the float ball and the other side is connected with the elastic piston through a pin. The bottom of the lower body and the connecting hole at the lateral side are separately provided with leaky nets. The utility model is characterized by good sealing property, larger air displacement and good closeness, besides the insulating contamination technology of the leaky nets effectively stops the foreign matter from the valve body, and is suitable for the hot water heating and the hot water boilers in the pipe network system.
Description
The utility model relates to a kind of valve, especially a kind of full-automatic exhaust valve that is used for water heating system.
Existing water heating system outlet valve is divided into manually and is automatic, the not exhaust of draining that automatic control pressure vent has, and the poor sealing performance that has, and exhaust obstruction, rate of fault height often appear.
The purpose of this utility model be to provide a kind of good seal performance, air displacement big, have an automatic control pressure vent of slipping through the net every dirty structure.
Outlet valve is made up of shell, valve seat, exhaust port, and shell is divided into upper body and lower body, and the valve seat in the upper body is fixed by the spiral shell select, and there is seal ring valve seat and joint, upper body, and pull bar one end is connected with ball float, and the other end is connected with the formula of bullet piston with pin; Lower body bottom and connection hole, side are separately installed with one and slip through the net, and attachment hole is with protecting cover outward.
The utility model adopts the ball float bracing structure, plays the formula piston, have good seal performance, air displacement is big, encapsulation is tight and flexible characteristic, it is slipped through the net every dirty technology, block impurity closely and can not enter valve in health, dirty permanent the keeping clean of valve core gone slick, be highly suitable for hot water heating and pipe network system water-heating boiler.
Fig. 1 the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shell is linked into an integrated entity by spiral shell select 11 by upper body 1 and lower body 12, valve seat 6 is fixing by spiral shell select 10 in the upper body 1, bullet formula piston 5 is arranged in the valve seat 6, ball float 2 is connected end weldering with pull bar 3 dead, and the other end connects by pin 4, and valve seat 6 has sealing column 7 and seal ring 8 with 1 joint, upper body, the centre has exhaust port 9, lower body 12 respectively has one to slip through the net 13 in bottom and side, and fixing with pressing plate 15 and Cross Recess Head Screw 14, the outside of attachment hole is with protecting cover 16,17.Valve is installed in hot water heating and other above pipe network system water-heating boiler, the peak of water pipe, i.e. and the gas position of easy gathering, valve answers accumbency to install, and gas can be risen up in the valve smoothly.When gas is full of, reach certain pressure, promote piston, gas is emitted from exhaust port.
