Abstract
The utility model discloses a ceramic fluidization valve, which is used for solving the problems that the existing fluidization valve is complex in structure, poor in sealing performance and short in service life. A valve body (1) and a valve cover (6) are connected by a first bolt (7); a valve core bracket (2) is connected with the valve cover (6) by a second bolt (8); coaxial holes are formed on the valve core bracket (2) and the valve cover (6); a cylindrical end of the valve core (5) is movably fitted with the hole on the valve core bracket; the arc-shaped end of the valve core (5) is fitted with the tapered surface of a valve seat (4) in a sealing manner; the valve seat (4) is statically fitted with the valve cover (6); a spring (3) is arranged between the lower plane at the arc-shaped end of the valve core (5) and the bottom surface of the valve core bracket; a channel (9) is arranged on the side surface of the valve core bracket (2); when the arc-shaped end of the valve core (5) leaves the valve seat (4), the hole on the valve cover is communicated with the inner cavity of the valve body (1) by the channel (9).
Description
Technical field:
The utility model is relevant with safety check.
Background technique:
The valve body of existing safety check and valve gap unitary moulding, the spool support is connected with the through hole whorl of valve body, the spool support is connected with axle sleeve, and axle sleeve is connected with spool, complex structure, make and assembling inconvenience, cost is high, and the valve seat on spool end and valve gap is by plane sealing, and the sealing surface wear-resisting property is poor, working life is short, easily causes leakage.
The model utility content:
The purpose of this utility model is to provide a kind of simple in structure, long service life, the ceramic fluidisation valve of good seal performance.
The utility model is achieved in that
The utility model pottery fluidisation valve, valve body 1 is connected by the 1st screw 7 with valve gap 6, spool support 2 is connected with valve gap 6 by the 2nd screw 8, on spool support 2 and valve gap 6, coaxial hole is arranged, hole on the post ends of spool 5 and spool support movingly, the arc tips of spool 5 coordinates with the conical surface seal of valve seat 4, valve seat 4 and valve gap 6 stationary fits, between the arc tips lower plane of spool 5 and spool support bottom surface, spring 3 is arranged, there is passage 9 side of spool support 2, lift off a seat 4 the time when the arc tips of spool 5, the hole on valve gap communicates by the inner chamber of passage 9 with valve body 1.
Described valve seat 4, spool 5 use stupaliths are made.
On the junction surface of valve body 1 and valve gap 6, the 1st seal ring 10 is arranged, on the junction surface of valve seat 4 and valve gap 6, the 2nd seal ring 11 is arranged.
Spool support of the present utility model and valve gap are connected by screw, and be simple in structure, and installation and maintenance is convenient.Valve seat is respectively the conical surface with the sealing surface of spool and contacts with the cambered surface line, and valve seat and spool are made with stupalith, good seal performance, long service life.Valve seat and valve gap stationary fit have O-ring seals, are convenient to change.
Description of drawings:
Fig. 1 is structural drawing of the present utility model.
Embodiment:
Valve body 1 is connected by screw 7 with valve gap 6.Spool support 2 is connected with valve gap 6 by screw 8, on spool support 2 and valve gap 6, coaxial hole is arranged, hole on the post ends of spool 5 and spool support movingly, valve seat 4 and valve gap 6 stationary fits, the arc tips of spool 5 coordinates with the conical surface line contact sealing of valve seat 4, between the arc tips lower plane of spool 5 and spool support bottom surface, spring 3 is arranged.There is passage 9 side of spool support 2, lifts off a seat 4 the time when the arc tips of spool 5, and the hole on valve gap communicates by the inner chamber of passage 9 with valve body 1.Valve seat 4, spool 5 use stupaliths are made.On the junction surface of valve body 1 and valve gap 6, seal ring 10 is arranged, on the junction surface of valve seat 4 and valve gap 6, seal ring 11 is arranged.
