Description
Technical field
The present invention relates to valve arrangement technical field, specially a kind of hydraulic control conveying casting resin stop valve.
Background technology
Stop valve, is also pipe valve, is a kind of most popular valve, and the closure principle of stop valve is, by valve thick stick pressure
Power, makes valve clack sealing surface be brought into close contact with sealing surface of seat, prevents flow of media, and general stop valve is controlled using handwheel, also had
Hydraulic control.
With reference to the above, hydraulic stop valve is generally used for large-scale pipeline, is driven for such occasion using traditional handwheel
It is dynamic relatively difficult, therefore take the mode of hydraulic control, meanwhile, hydraulic stop valve can not effectively carry out that viscosity is larger or stream
Contain particulate matter cut-off work in vivo, being primarily due to the friction impact of particulate matter and plunger causes the damage of plunger, so, root
Shortcoming according to existing stop valve is improved, and the versatility and practicality of stop valve can be caused further to be lifted.
The content of the invention
Casting resin stop valve is conveyed it is an object of the invention to provide a kind of hydraulic control, when possessing reduction hydraulic-driven
Required pressure, for viscosity to be big or can reduce the advantage of friction impact during fluid containing particulate matter, solves tradition
Required pressure is larger during hydraulic stop valve hydraulic-driven, and is used greatly or under the fluid situations containing particulate matter in viscosity, causes
The problem of valve is easily damaged.
To achieve the above object, the present invention provides following technical scheme：A kind of hydraulic control conveys casting resin stop valve,
Including valve body and hydraulic pump, described valve body one end is fixedly connected with inlet pipe, and the valve body other end is fixedly connected with outlet pipe, the valve body side
Gim peg is provided with face, the hydraulic pump bottom is fixed with hydraulic pressure rod member, and the hydraulic pressure rod member bottom is fixed with valve rod, described
Valve rod bottom is welded with post nut, and the post nut lower end is fixed with plunger, the plunger bottom face and is welded with stopper head, institute
State and cast steel baffle plate is welded with plunger one side, the diameter of section and the channel diameter one of valve inner formation of the plunger
Cause, and raised line is evenly arranged with the two sides of plunger, valve body corresponds to and sets fluted on the inwall of raised line, the width of the raised line
Degree is consistent with the width of groove.
It is preferred that, the valve rod upper end passes valve body and is fixedly connected with hydraulic pressure rod member, and valve rod lower end is arranged on valve inner.
It is preferred that, it is provided with pad between the nut and plunger.
It is preferred that, the stopper head is formed by iron-carbon alloy casting.
It is preferred that, the cast steel baffle surface is uniformly provided with thin through hole.
It is preferred that, the raised line is cast with plunger integrated punching, and groove is cast with valve body punching press.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, the present invention according to stop valve easily by viscosity is big or impact friction of fluid containing particulate matter under easily by
To the shortcoming of damage, when plunger blocks fluid, a cast steel baffle plate is provided with plunger front end, cast steel baffle plate can necessarily journey
The effect of spacer particle thing on degree, it is to avoid plunger directly contacts with particulate matter and causes plunger to damage.
2nd, the present invention is in plunger bottom end, there is provided intensity is higher, the more preferable stopper head of wearability can also be from certain journey
The service life of valve is improved on degree.
3rd, the larger situation of required hydraulic coupling, the process moved down in plunger when the present invention drives according to hydraulic stop valve
When, plunger side and valve interior wall are provided with adaptable raised line and groove, the plunger made, which is moved down, more to be smoothed out, and can be reduced
Required hydraulic coupling during driving.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1 to 4, a kind of embodiment that the present invention is provided：A kind of hydraulic control conveys casting resin stop valve, bag
Valve body 2 and hydraulic pump 6 are included, the one end of valve body 2 is fixedly connected with inlet pipe 1, and the other end of valve body 2 is fixedly connected with outlet pipe 10, the one side of valve body 2
On be provided with gim peg 3, gim peg 3 is primarily served so that the overall more firm effect of valve body 2, the bottom of hydraulic pump 6 is fixed with
Hydraulic pressure rod member 5, the power resources that driving hydraulic pressure rod member 5 is flexible when hydraulic pump 6 works when being Valve controlling, the bottom of hydraulic pressure rod member 5
Valve rod 4 is fixed with, the upper end of valve rod 4 passes valve body 2 and is fixedly connected with hydraulic pressure rod member 5, and the lower end of valve rod 4 is arranged on inside valve body 2, valve
The bottom of bar 4 is welded with post nut 7, and post nut 7 is attached the work of valve rod 4 and plunger 8, and the lower end of post nut 7 is fixed with plunger
8, pad is provided between nut 7 and plunger 8, pad plays a part of being welded with stopper head on compensator or trimmer pressure, the bottom face of plunger 8
9, stopper head 9 is formed by iron-carbon alloy casting, and use intensity is higher, and the more preferable stopper head 9 of wearability can increase valve
Cast steel baffle plate 11 is welded with service life, the one side of plunger 8, the surface of cast steel baffle plate 11 is uniformly provided with thin through hole, cast steel
Baffle plate 11 can downwardly together be moved with plunger 8, can play a part of spacer particle thing to a certain extent, it is to avoid particulate matter
Or the big fluid of viscosity for a long time with the impact friction of plunger 8, it is to avoid the damage of plunger 8, the diameter of section of plunger 8 with inside valve body 2
The channel diameter of formation is consistent, and channel diameter can unanimously ensure sealing during valve closure, and on the two sides of plunger 8
Even be provided with raised line 12, the inwall of the correspondence raised line 12 of valve body 2 sets fluted 13, and raised line 12 is cast with the integrated punching of plunger 8,
Groove 13 is cast with the integrated punching of valve body 2, and the width of raised line 12 is consistent with the width of groove 13, uses raised line 12 and groove 13
The mode of cooperating so that plunger 8, which is moved down, more to be smoothed out, and can reduce pressure required during driving.
Specifically used mode：In present invention work, the installment work of this valve is first completed, after installing, when needs are closed
When closing valve, hydraulic pump 6 works, and the driving hydraulic pressure of hydraulic pump 6 rod member 5 stretches downwards, and hydraulic pressure rod member 5 is downward with ovable valve stem 4, finally
The raised line 12 of the two sides of plunger 8 under the effect of the pressure of plunger 8 is smoothly moved down in groove 13, so that plunger 8 is moved down, is displaced downwardly to
In the passage that valve body 2 is internally formed, and plunger 8 is brought into close contact, now, and cast steel baffle plate 11 is also moved downward with plunger 8, cast steel
