Throttling valve pocket 131 is provided with restriction 133, and the adjusting screw rod 111 is provided with lock nut with the junction of outer valve 100
112, the uninterrupted in oil circuit is adjusted by the size of the control orifice 133 of adjusting screw rod 111.
Formed successively (as shown in figure 1, from left to right) from free end to fixing end vertically in the inner valve body 200
Hydraulic control push rod chamber 210 in place, cone valve mouth 220, steel ball chamber 230 in place and cut-off valve seat installation cavity 240, the hydraulic control push rod is in place
Hydraulic control push rod 211, the steel ball 231 of coaxial line are sequentially installed with chamber 210, steel ball chamber 230 in place and cut-off valve seat installation cavity 240
With cut-off valve seat 241 (as shown in Fig. 2 from left to right).The valve seat mouth of the cut-off valve seat 241 is provided with and the throttling valve core
121 inner conical surfaces 242 to match, manually rotate adjusting screw rod 111 and promote throttling valve core 121, be allowed to cross one-way throttle
Orifice 133 on valve pocket 131 contacts to form linear sealing with ending the inner conical surface 242 of valve seat 241, plays the work for blocking oil circuit
With.In addition, linear sealing can be also formed between steel ball 231 and cone valve mouth 220.
Wherein, the one-way throttle valve pocket 131, steel ball 231 and hydraulic control push rod 211 be respectively equipped with throttling back-moving spring 132,
Steel ball back-moving spring 232 and hydraulic control push rod back-moving spring 212.
Specifically, the compound liquid control one-way throttle valve operation principle of Novel threaded plug-in proposed by the present invention will be described below
(for ease of description, hereafter by the compound liquid control one-way throttle valve abbreviation combination valve of Novel threaded plug-in), as shown in figure 3, at this
Oil inlet (1# hydraulic fluid ports) is offered between the free end of inner valve body 200 and hydraulic control push rod 211 on the valve block 300 of combination valve inserting, in
Oil-out (2# hydraulic fluid ports) is offered at restriction 133, extending to one end outside inner valve body in hydraulic control push rod is provided with hydraulic control mouth (3# oil
Mouthful).
A, monodirectional locking function (2# hydraulic fluid ports → 1# hydraulic fluid ports)
As shown in figure 3, when 1# hydraulic fluid ports and 3# hydraulic fluid ports, not have pressure oil to enter fashionable, and steel ball 231 is in steel ball back-moving spring 232
Under effect, the cone valve mouth 220 for being depressed into inner valve body 200 forms linear sealing, and hydraulic oil can not be flowed from 2# hydraulic fluid ports to 1# hydraulic fluid ports；Make
Combination valve has the monodirectional locking function in 2# hydraulic fluid ports → 1# hydraulic fluid ports direction；
B, unidirectional fuel-displaced function (1# hydraulic fluid ports → 2# hydraulic fluid ports)
As shown in figure 4, pressure oil, after the 1# hydraulic fluid ports of combination valve enter, steel ball 231 is in the presence of pressure oil from internal valve
Push up and open on the cone valve mouth 220 of body 200, through cut-off valve seat 241 flow to one-way throttle valve pocket 131, one-way throttle valve pocket 131 can
It is axially moved under the promotion of pressure oil along throttling valve core 121, departs from cut-off valve seat 241 and form passage, 1# hydraulic fluid ports → 2# oil
The flowing in mouth direction is not by the control of choke valve 121；Make combination valve that there is unidirectional fuel-displaced function (1# hydraulic fluid ports → 2# hydraulic fluid ports)；
It is multiple in steel ball back-moving spring 232 and throttling to cancel the pressure oil of 1# hydraulic fluid ports, steel ball 231 and one-way throttle valve pocket 131
Resetted in the presence of the spring 132 of position, combination valve is returned to monodirectional locking state.
C, hydraulic control meter out function (2# hydraulic fluid ports → 1# hydraulic fluid ports)
As shown in figure 5, when 3# hydraulic fluid ports, to have fluid control pressure oil to enter fashionable, and hydraulic control push rod 211 is under the promotion of fluid control pressure oil
Pressure pushes up steel ball 231 from the cone valve mouth 220 of inner valve body 200 opens, and the hydraulic oil of 2# hydraulic fluid ports is passed through one-way throttle valve
Restriction 133 on set 131, flowed back by ending valve seat 241 to 1# hydraulic fluid ports；The size of restriction 133 by throttling valve core 121
Control；2# hydraulic fluid ports typically connect actuator (such as oil cylinder), and the opening face of restriction 133 can be reduced by rotating clockwise adjusting screw rod 111
Product, so as to increase oil return resistance, slows down the movement velocity of actuator；Otherwise throttling can be increased by rotating counterclockwise adjusting screw rod 111
133 open areas of mouth, make the movement velocity of actuator increase；So make combination valve that there is the hydraulic control in 2# hydraulic fluid ports → 1# hydraulic fluid ports direction
Meter out function, and it is adjustable manually that restriction 133, which opens size,.
Cancel the fluid control pressure oil of 3# hydraulic fluid ports, hydraulic control push rod 211 departs from the presence of hydraulic control push rod back-moving spring 212
Steel ball 231 resets, and combination valve is returned to monodirectional locking state.
D, manual shutoff function
As described in Figure 6, the adjusting screw rod 111 that turns clockwise manually promotes throttling valve core 121, is allowed to cross one-way throttle valve
Orifice 133 on set 131 contacts to form linear sealing with ending the inner conical surface 242 of valve seat 241, and hydraulic oil can not be in 1# and 2#
Flowed between hydraulic fluid port, form two-way stop function, rotate counterclockwise regulation spiral shell 111 can release two-way stop function manually.
To sum up, in the compound liquid control one-way throttle valve of Novel threaded plug-in provided in an embodiment of the present invention, will unidirectionally save
Three stream valve, stop valve and hydraulic control one-way valve relatively independent outboxes are integrated into a complex hydraulic valve part, can be significantly reduced
Valve member quantity in hydraulic control circuit, is greatly reduced volume, meets the requirement of hydraulic control valve group miniaturization, collects one-way lock
Fixed, unidirectional oil-feed, hydraulic control meter out, manual shutoff function are integrated, and have the characteristics of simple in construction, simple installation.
The preferred embodiments of the present invention are above are only, any restrictions effect is not played to the present invention.Belonging to any
Those skilled in the art, in the range of technical scheme is not departed from, to the invention discloses technical scheme and
Technology contents make the variation such as any type of equivalent substitution or modification, belong to the content without departing from technical scheme, still
Belong within protection scope of the present invention.
