The hydraulic pressure adjusting valve of the embodiment of the utility model is described below with reference to the drawings.

The hydraulic regulating valve provided by the utility model is mainly applied to a hydraulic system of production equipment (such as a braiding machine or a material conveying device and the like) and can control the pressure, the flow and the flow direction of oil.

As shown in fig. 1 and 2, the hydraulic pressure regulating valve according to the embodiment of the present utility model may include: a valve body 1, a first regulating assembly 2, a second regulating assembly 3 and a valve core 4.

Wherein, the both ends of valve body 1 communicate with hydraulic line (not shown in the figure) respectively, and the inside of valve body 1 is equipped with disk seat 11, and first regulation subassembly 2 sets up on valve body 1, and second regulation subassembly 3 sets up on first regulation subassembly 2.

The hydraulic line described in this embodiment is an oil line of a hydraulic system of a production apparatus (e.g., a braiding machine).

The valve core 4 is disposed inside the valve body 1, and the valve core 4 may include: a stem 41, a cross 42 and a flap 43.

Wherein, the one end of the body of rod 41 is connected with first adjusting part 2, and the cross joint 42 sets up between the other end of the body of rod 41 and valve clack 43, and valve clack 43 is contradicted on disk seat 11.

For clarity of description of the above embodiment, in another embodiment of the present utility model, the first adjusting assembly 2 may comprise: a cylinder 21, a spring 22 and two connection plates 23.

Wherein, barrel 21 integrated into one piece is on valve body 1, and spring 22 sets up between two connecting plates 23, and two connecting plates 23 movably set up in the inside of barrel 21, and the one end of body of rod 41 is connected with one connecting plate 23.

As a possible case, referring to fig. 1, in order to prevent hydraulic oil from entering the interior of the cylinder 21 through a gap between the rod 41 and the valve body 1 under high pressure, a packing seal (not shown) may be provided in the gap between the rod 41 and the valve body 1, making use of its high pressure and wear resistance properties.

Further, in one embodiment of the present utility model, the second adjusting assembly 3 may include: a valve cap 31 and a bolt 32.

Wherein, valve gap 31 sets up on barrel 21, and bolt 32 and valve gap 31 threaded connection, the one point of bolt 32 is contradicted on another connecting plate 23.

It should be noted that the valve cover 31 described in this embodiment is provided on the cylinder 21 by a fixing member, which may be any one of a bolt, a screw, or a rivet, and is not particularly limited herein.

It will be appreciated that the valve cap 31 and the valve body 1 are separately provided, so that a later worker can conveniently overhaul the inside of the valve body 1 by opening the valve cap 31.

As a possible case, in order to avoid oil leakage between the valve cover 31 and the valve body 1, a gasket (not shown in the drawings) may be provided between the valve cover 31 and the valve body 1, and in order to extend the service life of the gasket, a gasket in which steel wires are embedded may be used.

Specifically, the worker installs the device in the hydraulic system of the knitting machine, and normally, the valve clack 43 is abutted against the valve seat 11, and the hydraulic regulating valve is in a closed state.

When the oil pressure of one side (oil inlet) of the hydraulic regulating valve is higher than the oil pressure of the other side (oil outlet) of the hydraulic regulating valve, the hydraulic oil pushes the valve clack 43 to ascend, the valve clack 43 pushes the rod body 41 to ascend, the rod body 41 pushes a connecting plate 23 to move in the cylinder 21, and the spring 22 is compressed and deformed.

Meanwhile, the hydraulic oil is replenished to the side with low oil pressure, and the valve clack 43 tilts due to the connection effect of the cross joint 42, referring to fig. 2, at this time, the hydraulic oil collides with the valve clack 43, the valve clack 43 plays a guiding role, and the hydraulic oil exerts an inclined acting force on the surface of the valve clack 43, so that the pressure loss of the oil can be reduced to a certain extent.

Because the hydraulic oil is used for a long time, partial water vapor can not enter the hydraulic oil, and the water vapor forms small bubbles in the hydraulic oil and flows along with the hydraulic oil, when the hydraulic oil impacts the inclined plane of the valve clack 43, the bubbles are not easy to shrink or break suddenly due to small acting force, and the bubbles continue to move along with the hydraulic oil, so that cavitation in the valve body 1 is weakened, and the service life of the device is finally prolonged.

When the oil pressure of the other side (oil outlet) of the hydraulic regulating valve is higher than that of the one side (oil inlet), the hydraulic oil flows back, and under the combined action of the hydraulic oil and the spring 22, the valve clack 43 is abutted against the valve seat 11, so that the device is in a closed state.

When the reaction speed of each load in the hydraulic system needs to be changed (namely, the instantaneous flow of hydraulic oil is changed), at the moment, a worker can rotate the bolt 32 to enable the bolt 32 to be screwed out, so that the distance between the two connecting plates 23 is changed, the stroke of the valve core 4 is changed, the instantaneous flow of the hydraulic oil is increased, and the reaction of each load is more sensitive.

In one embodiment of the present utility model, further comprising: auxiliary assembly 5, auxiliary assembly 5 may comprise: reinforcing plate 51 and channel 52.

Wherein the reinforcing plate 51 is provided between the valve body 1 and the first regulating member 2, and the passage 52 penetrates the cylinder 21, the reinforcing plate 51, and the valve body 1 in this order.

It should be noted that the thickness of the reinforcing plate 51 described in this embodiment is larger than the diameter of the passage 52.

Specifically, when the oil pressure of the other side (oil outlet) of the device is greater than that of one side (oil inlet), part of the hydraulic oil can enter the cylinder 21 through the channel 52, on one hand, one connecting plate 23 can be pushed to move downwards, so that the closing of the valve clack 43 is accelerated, and on the other hand, lubrication can be carried out between the connecting plate 23 and the cylinder 21.

In one embodiment of the utility model, as shown in fig. 2, the outside of the flap 43 is surrounded by a plurality of sealing rings 61.

Specifically, the sealing ring 61 can increase the tightness between the valve clack 43 and the valve seat 11 on one hand, and on the other hand, when hydraulic oil pushes the valve clack 43 to collide with the valve seat 11, the sealing ring 61 can play a certain buffering role, so that the valve clack 43 is prevented from beating the valve seat 11, the valve clack 43 is finally prevented from being damaged, and the service life of the device is prolonged.

In one embodiment of the present utility model, as shown in fig. 2, the two ends of the valve body 1 are respectively provided with flanges 71.

Specifically, a worker can install the present device in a hydraulic system of a production facility through the flange 71 using the fixing member.

As a possible case, in order to avoid oil leakage between the flange 71 and the hydraulic system, a gasket (not shown in the drawings) may be placed on the surface of the flange 71, and the gasket may be made of rubber.

As another possible case, in order to expand the application range of the device and facilitate the installation of the device in a hydraulic system, quick connectors (not shown) may be further disposed at two ends of the device, and the quick connectors may be in communication with hydraulic pipes in the hydraulic system.
