Abstract
The said trap consists of casing, base, hood, valve sheet, filtering net and screw. under the valve sheet, there is a sump being annular, spider or netted. The emulsion of engine oil and water often condensed on valve sheet is condensed in sump and is drained out of valve by the pressured draining gas. The pressent invention solves the problem of valve sheet and base adhesion owing to emulsion of engine oil and this ensures the normal operation of trap.
Description
The invention belongs to air valve with fixed attention.
At present the drain valve that uses as shown in Figure 1, by constituting by valve casing 1, valve seat 2, valve bonnet 3, valve outer cover 5, valve block 6, filter screen 9 and bolt 4,10.Valve block 6 is pressed on the valve seat 2, and working room's pressure is during greater than inlet hole pressure, and envelope is compressed into pore and weep hole.Pad 7,8 sealing valve casings 1, valve seat 2, valve bonnet 3.Valve seat 2 usefulness pins 11 link with valve casing 1.Valve bonnet 3 is spirally connected with valve casing 1.Valve outer cover 5 usefulness bolts 4 link with valve bonnet 3.In air inlet pipeline, bury filter screen 9 underground with removable form.Bolt 10 is positioned at filter screen 9 in the pipeline and sealing picks and places mouth.
The shortcoming of this drain valve is when containing the organic oil gas in the air inlet, and the emulsified liquid of aggegation machine oil and water on valve block 6 usually in the condensation journey makes valve block 6 and valve seat 2 or valve bonnet 3 adhesions, and then makes drain valve work not normal.
The objective of the invention is to propose a kind of improvement project, overcome its shortcoming aforementioned drain valve structure.
The present invention program's content is a kind of drain valve that is made of valve casing, valve seat, valve bonnet, valve block, filter screen and bolt, it is characterized in that being provided with the aggegation oil groove below the valve block.The aggegation oil groove can be a circular groove.Aggegation oil groove one also can be the radiation linear grooves.The aggegation oil groove also can be the net form groove.The aggegation oil groove can also be the slab groove.
The present invention program's characteristics are that the aggegation oil groove is set on valve block 6, with in the condensation journey usually on valve block 6 machine oil of aggegation and water-in-oil emulsion aggegation in groove, and with hydrophobic action next time, under the washing away of pressed gas outside the expulsion valve, make valve block keep cleaning surfaces, drain valve can proper functioning.
The present invention program's embodiment is as shown in drawings:
Fig. 1 is the unitary construction schematic representation of drain valve;
Fig. 2 is the aggegation oil groove floor map of valve block;
Fig. 3 is the sectional drawing of Fig. 2.
6.1 expression aggegation oil grooves among the figure.
Accompanying drawing is specified the present invention program in conjunction with the embodiments:
The present invention program only is to establish on the valve block aggegation oil groove to the improvements of as shown in Figure 1 prior art drain valve.The shape of aggegation oil groove 6.1 and structure can be in shown in Fig. 2,3.Fig. 2 provides the simplest a kind of slab groove.The slab groove can have a concentric circle annular groove, and two, three or many concentric circle annular grooves also can be arranged.But the valve block plane is less, should not the close annular groove of establishing.In like manner, center radiation linear grooves can have one or more, is advisable with three equally spaced grooves.
When establishing two concentric circle annular grooves, the position of inside and outside two concentric circle annular grooves can be to place , the radius; Also can be to place ,
Radius.
The present invention program's valve block aggegation oil groove 6.1 can also be many involute shape grooves, or the net form groove of straight line or camber line interleave.The section of groove can be an arc, also can be inverted cone.The reversed cone angle of inverted cone is unsuitable excessive or too small, can between 45 °-135 °, select, and can be 60 °, 90 °, 120 °; The notch cross-section size also changes thereupon.Groove depth is advisable about with the thick of valve block, also can be or , crosses shallow then oil-collecting weak effect, crosses that deeply then valve block intensity is impaired.
A kind of size of monocycle groove valve block of definite specification can be:
Valve block diameter: 31.5
Circular groove diameter: 17
Channel section is an inverted cone, reversed cone angle: 90 °
Valve block is thick: 2.3 ± 0.02
Valve block groove depth: 0.7
The aggegation oil groove is set on the present invention program's the valve block, with in the condensation process usually on valve block 6 the emulsified liquid aggegation of the machine oil of aggegation and water in groove, and with hydrophobic action next time, under the washing away of pressed gas outside the expulsion valve, make valve block keep cleaning surfaces, solved the problem of lubricating oil emulsion liquid adhesion valve block, valve seat, made the drain valve can proper functioning.
