Description
Technical field
It the utility model is related to one kind to surge choke valve, belong to mechanical engineering field..
Background technology
When carrying out drill pump pressure experiment, water flow pressure is typically up to 35MPa, at this time, it may be necessary to add at high-pressure outlet
A choke valve is filled to realize the throttling action to High-Pressure Water, so as to reach the effect of supercharging.Section used in the market
Stream valve is mostly the choke valve of hand, generally requires manually to carry out hand wheel rotating to adjust valve in pressure test operating process
Valve openings of sizes, this process is often than relatively hazardous.
The content of the invention
The purpose of this utility model is to provide one kind and surged choke valve, to solve in drilling well pump pressure experiment regulation section manually
The danger that stream valve is brought.
To realize above-mentioned purpose, the technical solution of the utility model is：One kind choke valve that surges includes throttle body,
Throttle body includes valve rod, and the threaded one end of the axial direction of valve rod is connected with valve stem nut, is fixedly connected on valve stem nut
There is valve element, gland is arranged with the outer circumference surface of valve stem nut, be provided between gland and valve stem nut and be used to make valve stem nut edge
The Stop structure of valve rod axial direction movement, the other end of the axial direction of screw rod is fixedly connected with gear, connected on gear
Engine.
Stop structure includes the keyway being oppositely arranged on valve stem nut and gland, in addition to is arranged in keyway
Feather key.
Engine is vane motor.
Trapezoidal thread connection is threaded between valve rod and valve stem nut.
The utility model compared with prior art, has the advantages that：
The utility model by the rotation direction of far distance controlled vane motor come control the lifting of valve rod and under
Drop, so as to which the folding size to choke valve is adjusted, the throttle valve opening size for changing manual rotation's handwheel to adjust
Mode, and then avoid making one the danger in hyperbaric environment operation.
In addition between valve stem nut and valve rod use with auto-lock function and transmission efficiency it is higher trapezoidal thread connection, from
And it is further, used between valve stem nut and valve rod with auto-lock function and the higher trapezoidal thread of transmission efficiency connects, connection can
Lean on, and ensure that restriction does not change with the change of pressure, under conditions of super-pressure, throttling output pressure is constant, energy
Peril caused by effectively avoiding throttling failure.
Brief description of the drawings：
Fig. 1 is a kind of structural representation for the choke valve that surges of the utility model；
Fig. 2 is hydraulic principle schematic diagram of the present utility model.
In figure：1- vane motor 2- rotor 3- gear 4- valve rod 5- valve body 6- valve stem nut 7-O shape circles
8- valve element 9- valve seat 10- sealing ring 11- feather key 12- glands.
Embodiment：
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
A kind of embodiment for the choke valve that surges of the utility model, as shown in Figure 1：Hydraulic throttle valve includes throttle body,
Throttle body includes valve 5, and valve stem nut 6 is set with valve body 5, is arranged between the upper axial end and valve body 5 of valve stem nut 6
The position that the outer circumference surface of gland 12, the inner peripheral surface of gland 12 and valve stem nut 6 is relative offers keyway, is provided with and leads in keyway
Xiang Jian, keyway and feather key constitute Stop structure, wherein feather key a effect be used to preventing valve stem nut relative to
Gland rotates, and another effect of feather key is that the direction of valve stem nut face value feather key moves up and down；The axle of valve stem nut 6
Valve element 8 is welded with to lower end, the effect of valve element is disconnected and together with fluid flow paths；It is set with the outer circumference surface of valve element 8
Sealing ring 10, groove is provided with the outer circumference surface of sealing ring 10, o-ring 7 is provided with groove；The inner periphery inner sleeve of valve stem nut 6
Equipped with valve rod 4, connected between valve rod 4 and valve stem nut by trapezoidal thread, wherein trapezoidal thread connection with auto-lock function and
Transmission efficiency is higher, and trapezoidal thread connection ensure that restriction does not change with the change of pressure so that in super-pressure
Under the conditions of, throttling output pressure is constant, can effectively avoid peril caused by throttling failure；The upper axial end of valve rod 7 is fixed
Provided with gear 3, the rotor 2 that gear 3 stretches out with vane motor 1 is connected.
The utility model one kind surges choke valve operation principle as depicted in figs. 1 and 2：Hydraulic station 1 is drawn oil inlet and oil return and overflow
Flow tube line, it is connected on remote control case, control cabinet is made up of a three position four-way directional control valve 2 and hydraulic line, is pulled on control stick
When hydraulic motor rotate forward, moved down by gear reduction 3 with ovable valve stem 4, guide flat be provided between valve stem nut 6 and gland 12
Key 11, valve stem nut 6 is moved up and down with movable valve plug 8, and can not rotate, the convert rotational motion of valve rod is transported for straight line
It is dynamic, realize throttling.Hydraulic motor inverts on time under control stick, locked during middle position, is failure to actuate.
In addition, the vane motor in the utility model, can also be replaced with other motors.
In addition, Stop structure can also be one projection of setting on valve stem nut in the utility model, and in gland
Axial direction of the relative position along gland be extended a guide groove, pass through the raised cooperation with guide groove and realize and prevent
The rotation of valve stem nut, while valve stem nut is axially moved up and down along gland.
