Abstract
The utility model provides an automatic discharging and exhaust dual-purpose trap with an automatic water discharging function and an automatic air exhausting function. The utility model has two installing forms of a horizontal type and a vertical type. The performance is stable without the air blocking phenomenon. The utility model has the advantages of good tightness and high reliability.
Description
The utility model be a kind of not only can be used as hydrophobic automatically, but also can be used as self-bleeding dual purpose valve.
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 floating ball lever structure, and Rotate 180 ° when installing and using only, just can change to another function from a function.2. but be normally closed when making drain valve, if the too light sealing valve port pressurized of ball float is not enough, leakiness.Be often to open when making outlet valve, if ball float is too heavy, the little sealing valve port pressurized of buoyancy is not enough, also leakiness.Now select ball float weight 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 reducing the size of valve, increasing the situation of valve port flow area, make problem also obtain good solution.
Details below in conjunction with this device of description of drawings: this valve is mainly by housing and access interface, and four parts such as valve seat and spool, ball float and lever, manual examination (check) door are formed, and inlet and outlet connectors is shown in the figure arrow.Housing (8) is the garden cartridge type, and its two ends seal with inlet end cap (10), outlet end cap (4).At two end cap upper offset inlet and outlet connectors, and make import and outlet be diagonal position (if on housing, drive outgoing interface into, will to be relative position, as a special-shaped four-way.) promptly one on the housing axis, one under the housing axis.Valve seat (12) is contained in outgoing interface, and ball float is on the housing center line.Incoming interface is connected with pipe network with a short silk (11).At a fluting of valve seat, to place lever (17), the other end car becomes screw thread, links with outgoing interface, and the valve port hole on the valve seat and axle Xiao hole are according to the biasing of valve seat center line symmetry.In when assembling the valve port hole is placed upper/lower positions, for prevent that dress is wrong or when installing and using valve seat rotate, one lock pearl (1) location is set on the opposite in valve port hole, and with nut (13) with valve seat and the lock pearl reinforce, (or outgoing interface also made internal thread, valve seat shortens, and the outside connects a short silk in addition as outlet).Be provided with seal ring (2) so that tight-closed at valve port.Spool (15) sealing surface is a garden ball-type structure, and the other end is connected with lever (17) with screw thread, and the other end of lever is connected with ball float (6) by connecting rod (5).Be connected with valve seat by axle Xiao (3) for ease of adjusting the fulcrum all increased adjustment nut (16), lever.Manual examination (check) door (7) is contained on the housing, over against the ball float center, and vertical in the formed plane of inlet and outlet connectors, in order to check and failure judgement.
Housing and end cap malleable iron, ball float is suppressed with cast aluminium or sheet copper, spool brass, and the sealing valve port circle is selected oil resistant rubber or polytetrafluoroethylene or brass for use according to temperature, other seal ring asbestos packing sheet, all the other each bodies are all used A
3Be processed into, steel part all needs zinc-plated processing.
Working condition below in conjunction with this valve of description of drawings: when making drain valve, according to aforementioned, because the below that outlet places valve at this moment valve is in closed condition, when vapour is entered in the valve by inlet union (11), if having water to form water level rises, water is raised to above ball float (6) one halfs, and spool (15) will leave sealing valve port circle (2), and valve is in opening state.Water is discharged by valve seat (12), is lower than ball float one half when water drops to, and valve enters next circulation from newly cutting out.
When making outlet valve, according to aforementioned (be with respect to drain valve install and use the position) along its axis Rotate 180 °, because outlet places the top of valve, at this moment valve is in opening state, when water is entered in the valve by inlet union (11), gas original or that newly bring into will be discharged by valve seat (12), water level rises, and water is raised to above ball float one half, and spool is by upper valve port seal ring (2), valve is in closed condition, if have gas to enter again, drawdown then, water drops to and is lower than ball float one half, valve enters next circulation from new unlatching.
Make horizontal usefulness, refer to that the housing axis is horizontal.Position as shown in drawings.
Make vertical usefulness, refer to that the housing axis is in vertical position, at this moment as long as valve seat (12) and lever (17) are respectively prolonged its oneself axis to be turned to, re-assemblying can be vertical by horizontal change, and its action principle is with horizontal.
The sealing that also can improve various valves in addition according to the water seal and the sealing gland principle of this valve.
