Description
Technical field
The present invention relates to a kind of cone valve type direct acting big flow water valve with damping piston is prevented under in particular to a kind of big flow
The only Direct Action Type big flow water valve that valve port is automatically closed.
Background technique
From the hydromechanical equation of momentum it is found that when liquid flows, liquid stream to the direction of the active force of spool always towards
The direction for trying hard to make valve port to close, and directly proportional with uninterrupted, thus high-volume hydraulic valve be easy to appear outlet liquid stream
Unstable situation.Direct Action Type big flow water valve has the following disadvantages: that, when flow increases, valve port can be certainly because of the effect of liquid stream power
Row is closed, thus reduce flow, it is small when big when water outlet shows as liquid stream, stable flow cannot be obtained.
Summary of the invention
A kind of cone valve type direct acting big flow water valve with damping piston of the present invention by adjusting screw (1), spring pocket (2), lead
To bar (3), electromagnet (4), electromagnetic core (5), middle valve body (6), water outlet (7), water inlet (8), damping piston (9), water inlet
Valve body (10), cone valve (11), annular groove (12), bias current piston (13), diaphragm plate (14), pull rod piston (15), air scoop (16), ball
Head pull rod (17), sealing ring (18), spring (19), electromagnetic valve body (20) composition.
The bias current piston (13) and damping piston (9) be it is integrated, bias current piston (13) is in left side and pull rod piston
(15) it being connected with integrally, the bulb of ball-head tension rod (17) is located between bias current piston (13) and pull rod piston (15), and
From pull rod piston (15), central hole is pierced by, and is used and is threadedly coupled between electromagnetic core (5)；When electromagnet (4) obtains electric, electromagnetism
Iron core (5) drives that ball-head tension rod (17), pull rod piston (15), bias current piston (13) and damping piston (9) are whole moves to left, open into
Access between the mouth of a river (8) and water outlet (7)；Conversely, electromagnet power loss, under the effect of spring (19) elastic force, pull rod piston
(15), bias current piston (13) is integrally moved to right with damping piston (9), and the access between water inlet (8) and water outlet (7) is cut off；
After the damping piston (9) moves to left, water valve starts to intake, and water flow enters water inlet valve body (10) from water inlet (8)
Afterwards, because damping piston (9) side is a flat structure, thus water inlet (8) water pressure can act on damping piston (9) bottom,
The liquid stream active force that the part that valve port water inlet generates closes valve port can be cut down, both sides can be played the role of: on the one hand
Play dynamic hydraulic damping in cone valve (11) breakdown, to improve the stability of cone valve (11), on the other hand for guaranteeing cone
Valve (11) will not tilt after opening, to improve the static characteristic of valve；
Annular groove (12) are provided on the bias current piston (13), to change the liquid flow path direction of water outlet, generate one
With the jet flow force of spring force opposite direction, liquid stream force increment caused by being increased with counteracting because of flow makes the inlet pressure of valve not
It is influenced by changes in flow rate, to obtain the pressure-flow characteristic of big flow level, be conducive to raising valve passes through flow；
Middle valve body (6) is equipped with air scoop (16), and therefore, bias current piston (13) will not be because space be close during moving back and forth
Close the additional air resistance to be formed.
Compared with prior art, the beneficial effects of the present invention are:
(1) damping piston is used, therefore valve port will not close under heavy traffic condition because liquid stream power acts on；
(2) it is provided with annular groove on bias current piston, changes the liquid flow path direction of water outlet, counteract bullet caused by increasing because of flow
Spring force increment, improve valve passes through flow；
(3) structure is simple, and steady flow result is good.

Damping piston (9), water inlet valve body (10), cone valve (11), annular groove (12), bias current piston (13), diaphragm plate (14), pull rod piston
(15), air scoop (16), ball-head tension rod (17), sealing ring (18), spring (19), electromagnetic valve body (20) composition.
Referring to Fig.1, shown in Fig. 3, electromagnet (4) is powered, and attracts electromagnetic core (5) to move to left simultaneously compressed spring (19), causes
Ball-head tension rod (17) drives bias current piston (13) to move to left, and opens cone valve (11), and damping piston (9) is driven to move to left, water valve starts
Water inlet, after water flow enters water inlet valve body (10) from water inlet (8), because damping piston (9) side is a flat structure, water inlet
(8) thus water pressure can act on damping piston (9) bottom, cut down the liquid for closing valve port generated by valve port water inlet with part
Flow active force；
Referring to shown in Fig. 2, water flow after bias current piston (13), annular groove (12), changes the liquid of water flow along cone valve (11)
Direction is flowed, the jet flow force of one with spring force opposite direction are generated, liquid stream force increment caused by being increased with counteracting because of flow makes
The inlet pressure of valve is not influenced by changes in flow rate, to obtain the pressure-flow characteristic of big flow level, is conducive to improve valve
Pass through flow；
Shown in referring to Fig.1, electromagnet (4) is powered, and electromagnetic core (5), which moves to left, drives bias current piston (13) to move to left, due in
Valve body (6) is equipped with air scoop (16), and therefore, bias current piston (13) will not be because of the volume of airtight space formation during moving back and forth
Outer air drag；
After electromagnet (4) power loss, under the effect of spring (19) elastic force, electromagnetic core (5) pushes ball-head tension rod (17) to drive
Bias current piston (13) moves to right, and closes cone valve (11), and during this, damping piston (9) is moved to right, damping piston (9) and water inlet valve body
(10) gap between is eliminated, and water inlet (8) water pressure that damping piston (9) bottom is formed disappears therewith, it can be ensured that cone
The reliable closing of valve (11).
