Detailed description of the invention
In conjunction with accompanying drawing, the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the pressure pilot operated directional control valve in water route includes ball valve 1, combination sealing pad I 2, combination sealing pad II 3, centre
Plate 4, end cap fastening bolt 5, end cap 6, spring I 7, spring II 8, end cap O 9, valve body 10, spool 11, sealing shroud 12, guiding
Band 13, sealing ring 14, bottom O 15, bottom 16, bottom fastening bolt 17, packing ring 18 and ball valve fix bolt 19.Its work
Make pressure of a relatively high, favorable sealing property, have manually and two kinds of on-off modes of hydraulic control simultaneously.
Specifically, water route is pressure pilot operated directional control valve, it is divided into upper valve and lower valve, connects as one, upper valve is ball
Valve 1, upper valve has valve port I A and valve port III C of the valve body both sides being positioned at ball valve and communicates all the time with valve port III C.
Having import P to communicate with valve port I A on the valve body 10 of lower valve, also valve port communicates with valve port II B, also has near valve
Valve port IV K of mouthful II B side, also have connection valve port I A, valve port II B and the passage of valve port IV K, valve port I A and valve port II B it
Between vias inner walls on have sealing shroud 12, have in passage spool 11, spool 11 one end have protruding by valve port IV K and valve port II B and
Valve port I A separates, and has the shaft shoulder in the middle part of spool 11, arranges spring I 7 and spring II 8 between shaft shoulder side and the valve body 10 of spool 11,
Meet and open pressure match problem, be that groove connects with valve port II B between the shaft shoulder and projection.
The cylinder coordinated between sealing shroud with vias inner walls (valve body) uses interference fit, through the magnitude of interference at 0.01mm extremely
Between 0.15mm;Spool and sealing shroud are formed by cone match and seal;Spring between spool and end cap is by spool and sealing
Sealing cone between set forces together and is in sealing state.Valve body uses stainless steel material with spool, and sealing shroud uses copper close
Closure material, through research and experimental demonstration repeatedly, in the case of working media is mining water, rustless steel coordinates with copper can be effective
Make both seal and reach preferable effect, can effectively solve scale and corrode the adverse effect brought, and under high pressure having
Effect is longer for service life.
Valve port IV K is separated with valve port II B by sealing ring by spool with valve body, all passes through O between end cap, bottom and valve body
Type circle seals.Ball valve is connected with valve A, B mouth by intermediate plate, and valve port contact surface is all sealed by combination sealing pad.
The operation principle of the present invention: valve port II B, valve port III C communicate all the time, when ball valve action bars is axially in parallel with valve body
Time, valve port I A and valve port III C connects, and the water under high pressure now come in from import P is in open position;When ball valve action bars and valve body
Time axially vertical, valve port I A is obstructed with valve port III C, and the water under high pressure come in from P mouth is in blocking state, if now valve port IV K has
When hydraulic oil effect and pressure reach to open pressure, the sealing cone between spool and sealing shroud is opened, and valve port I A passes through valve port
II B and valve port III C turns on, and the water under high pressure come in from import P is in open position, when valve port IV K pressure is less than unlatching pressure, and valve
Sealing cone between core and sealing shroud is closed current and is blocked.
The work process of the present invention: when needing the switch of Non-follow control water valve, only need to operate ball valve handle realize valve port I A,
The break-make of valve port III C;When needs hydraulic control water valve switchs, ball valve handle must be placed in the off, then pass through valve port
The hydraulic pressure break-make of IV K and the interaction of spring force, make spool at spindle of valve body to slip, it is achieved close between spool and sealing shroud
The keying of front cover, and then control valve port I A, the break-make of valve port III C.
The present invention is by a kind of cooperation utilizing distinctive encapsulant and sealing means, it is achieved that scale high pressure resistant, anti-,
Etch-proof function, the problem efficiently solving hydraulic control water valve high pressure sealing.Realize hydraulic control water valve by function fusion to have simultaneously
For manual and the functional requirement of hydraulic control.
