Abstract
The utility model provides a double-purpose valve of automatic water discharge and gas discharge which can be used for automatic water discharge and automatic gas discharge. The closing and opening of the work is automatically decided according to the quantity of the water and the gas in the valve. No gas exists in water discharging and no water exists in gas discharging. When the utility model is used for the water discharge of the steam pipeline and the empty pressure pipeline and the gas discharge of the water heating system and hydraulic system, the energy resource using rate and the running safety can be improved.
Description
The utility model be a kind of promptly can be used as hydrophobic automatically, can be used as self-bleeding dual purpose valve again.
Existing drain valve and outlet valve in use have the deflation phenomenon when hydrophobic, the phenomenon of metalling run out is arranged during exhaust, and the two can not exchange use.
The purpose of this utility model is the function that integrates drain valve and outlet valve, provide a kind of make simple, easy-to-use, volume is little, the dual purpose valve of reliable operation.
The purpose of this utility model is finished as follows: waterborne being raised to a certain degree because of in the drain valve requirement valve can make spool unlatching, discharge water.And outlet valve requires the gas in the valve to be increased to (water reduces in other words) to a certain degree, can make spool open, discharge gas.This explanation: outlet will place the most down when 1. making drain valve, and when making outlet valve, outlet will place and go up most.2. two valves all close with water.According to these 2 the function of two valves is integrated in one: 1. this valve adopts the float-ball type structure, 2. and only gives to put upside down when installing and using, and just can change to another function from a function.3. select ball float heavily to equal heavy half of institute draining, when at this moment no matter making drain valve or when making outlet valve, sealing valve port pressurized equalization, can also form a water seal or air seal structure respectively simultaneously.So under the situation of the size that reduces valve, increase valve port flow area, make problem also obtain good solution.
Accompanying drawing is the longitudinal sectional drawing of a kind of concrete structure of this dual purpose valve.
Details below in conjunction with this dual purpose valve of description of drawings:
This dual purpose valve mainly is made up of valve casing and end cap, orifice plate and valve seat and ball float and spool.Valve casing (1) is a pipe collar, and two ends form housing with end cap (2) with screwed connection; Side inwards at the outlet end cap internal thread is equipped with valve seat (3), and an outside side is an outgoing interface; Side inwards at the inlet end cap internal thread is equipped with orifice plate (4), and an outside side is an accessing port; Nut (5) and spool (6) connect together ball float (8) through stud bolt (7), have one of spool to be inserted on the valve seat, have of nut to be inserted in the center hole of orifice plate, in order to avoid the ball float fluctuation.
Valve casing malleable iron, end cap cylinder iron, valve seat and orifice plate with brass, spool with teflon or brass, ball float with cast aluminium or sheet copper, iron sheet compacting, the available A3 of all the other each parts is processed into, but steel part needs zinc-plated processing.
Working condition below in conjunction with this valve of description of drawings: fluid passes in and out shown in reference arrow.
Do the drain valve time spent, outlet is placed below, and valve place closed condition at this moment is when gas is entered in the valve by import orifice plate (4), if having water to form water level rises, water is raised to above ball float (8) one halfs, and spool (6) will be lifted off a seat (3), and valve is in opening state, water begins to discharge, be lower than ball float one half when water drops to, valve cuts out again, enters next circulation.
Do the outlet valve time spent, outlet is placed the top, at this moment valve is in opening state, when water is entered in the valve by import orifice plate (4), gas original or that newly bring into will be discharged by outlet valve seat (3), and water level rises, and water is raised to above ball float one half, spool is by upper valve base, valve is in closed condition, if there is being gas to enter, and drawdown then, water drops to and is lower than ball float one half valve from new unlatching, enters next step circulation.
Claims (4)
1, a kind of automatic hydrophobic exhaust dual purpose valve of mainly forming by valve casing (1), end cap (2), valve seat (3), orifice plate (4), spool (6), ball float (8), it is characterized in that: the side inwards at the outlet end cap internal thread is equipped with valve seat [3], and an outside side is an outgoing interface; Side inwards at the inlet end cap internal thread is equipped with orifice plate [4], and an outside side is an accessing port; Ball float have one of spool to be inserted on the valve seat, have of nut to be inserted in the center hole of orifice plate, be no direct-connected free floating ball type structure therebetween.
2, dual purpose valve according to claim 1 is characterized in that: valve casing (1) be one the lengthening pipe collar, and with two end cap (2) be screwed connection.
3, dual purpose valve according to claim 1 is characterized in that: the weight of ball float (8) equals heavily half of self institute's discharge opeing.
4, according to claim 1,2,3 described dual purpose valves, it is characterized in that: by the sealing configuration of ball float (8) and formed water seal of valve seat (3) or sealing gland.
