For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

First embodiment of gate valve

In a first exemplary embodiment of the present disclosure, a gate valve 30a is provided.

Fig. 1 is a schematic structural view of a gate valve according to a first embodiment of the present disclosure. As shown in fig. 1, the gate valve 30a of the present embodiment includes: a gate valve body 31; a columnar connecting portion 32 provided at an upper portion of the gate valve body; and a cylindrical roller 33 provided at a lower portion of the gate valve body. Two guide grooves 37 are formed in the side surface of the gate valve body 31 in the longitudinal direction of the gate valve body. The cross section of the diversion trench 37 is rectangular, and the hydraulic diameter and depth are 2 mm.

Due to these guide grooves 37, the fluid continuously flows in the guide grooves 37 during the gate valve up-and-down movement, and in this case, the viscous medium is not easily adhered to the bottom and the side of the gate valve body 31.

When the gate valve 30a of this embodiment works, the high-pressure fluid in the pressure fluid chamber above the gate valve body 31 flows down from top to bottom along the diversion trench 37, so as to wash out the viscous medium adhered to the side surface of the gate valve body 31, and meanwhile, the viscous medium adhered to the bottom of the gate valve body 31 has a certain washing effect.

In addition, the fluid in the corresponding chamber may also flow back to the pressure fluid chamber through the diversion trench, so as to supplement the fluid in the pressure fluid chamber. This has considerable advantages for fast movement of the gate valve.

The position of the guide groove on the side surface of the gate valve body may be designed as needed, and the guide groove is provided only on the first side surface of the gate valve body facing the high-pressure chamber in consideration of not significantly affecting the fluid machine efficiency. However, the disclosure is not limited thereto, and in other embodiments of the disclosure, the guide grooves may be provided on both the first side surface (the side facing the high pressure chamber) and the second side surface (the side facing the low pressure chamber) of the gate valve body.

It should be clear to those skilled in the art that the cross-sectional shape of the flow guide groove can be designed as required, and for example, the flow guide groove can be semicircular, semi-elliptical, triangular, etc., and is not limited to the rectangular shape in the present embodiment. It should be noted, however, that the longer side of these shapes should be the side facing the side of the gate valve body in order to ensure the flushing effect.

In addition, it should be clear to those skilled in the art that the hydraulic diameter of the diversion trench can be designed as required, but it should be noted that if the hydraulic diameter of the diversion trench is too large, the fluid in the pressure fluid chamber will be consumed too much, and if the hydraulic diameter of the diversion trench is too small, the flushing effect will not be guaranteed, and when the viscous fluid of the fluid machine itself is used as the pressure fluid of the pressure fluid chamber, the pressure fluid can not be guaranteed to pass through the diversion trench smoothly. In view of the above, the hydraulic diameter of the channels is related to the pressure of the fluid flowing therein.

(1) When the pressure fluid is viscous media such as crude oil, lubricating grease and the like, the hydraulic diameter of the diversion trench is between 3mm and 10 mm;

(2) when the pressure fluid is water, lubricating oil and other common media with low viscosity, the hydraulic diameter of the diversion trench is between 2mm and 8 mm.

Still furthermore, those skilled in the art should understand that the number of the guiding grooves on the side surface of the gate valve body can be designed as required, and the number of the guiding grooves is generally set to 1 to 20, preferably 2 to 10, and most preferably 2 to 5, in order to avoid excessive consumption of the fluid in the pressure fluid chamber above the gate valve. The plurality of guide grooves on the same side face are bilaterally symmetrical about the gate valve symmetry plane. The symmetric surface of the gate valve is a surface which passes through the central line of the gate valve and is vertical to the first side surface and the second side surface.

In addition, in the present embodiment, the guide groove extends in the longitudinal direction of the gate valve body, but the present disclosure is not limited thereto, and in other embodiments of the present disclosure, the guide groove may be inclined or curved, that is, the extending direction of the guide groove only has a component in the longitudinal direction of the gate valve body as a whole.

To further prevent the sticking of viscous medium at the bottom surface of the gate valve body, in some embodiments of the present disclosure, the guide channel 37 may also extend to the bottom surface of the gate valve body 31. Furthermore, in some other embodiments of the present disclosure, the guiding groove does not necessarily extend from the top surface of the gate valve body to the bottom surface of the gate valve body, but may be only one segment, not extending to the bottom surface of the gate valve body, as long as it has a component in the longitudinal direction of the gate valve body.

It will be clear to the person skilled in the art that the gate valve body may be strip-shaped or plate-shaped. With respect to the stud bumps 32 in the gate valve, their primary function is to interface with the upper gate valve reset mechanism, which is not necessary to practice the present disclosure. In other embodiments of the present disclosure, the pillar-shaped connection portion on the gate valve may be omitted or multiple.

Referring to fig. 1, in order to reduce friction between the gate valve 30a and the rotor assembly, cylindrical rollers 33 are provided at positions where the lower portion of the gate valve contacts the corresponding rotor assembly. It will be understood by those skilled in the art that the presence or absence of the cylindrical roller 33 does not affect the practice of the present disclosure.

Referring to fig. 1, in the present embodiment, a gate valve cavity 36 opened upward is formed in the gate valve body 31. The gate valve chamber can reduce the weight of the gate valve, save materials and improve the driving efficiency on the one hand, and can also be used as a pressure fluid storage space (detailed in the following embodiments) on the other hand. The shape of the gate valve chamber 36 is not limited, and may be a rectangular parallelepiped chamber, a cylindrical chamber, or another chamber.

It should be noted that the volume of the gate valve cavity is strictly limited, and the volume should not have too great influence on the strength of the gate valve body, and at the same time, the arrangement of the guiding groove on the side surface (or bottom) of the gate valve and the roller on the bottom of the gate valve cannot be influenced.

Second, second embodiment of gate valve

In a second exemplary embodiment of the present disclosure, a gate valve 30 is also provided_b。

Referring to fig. 1 and 2, a gate valve 30 of the present embodiment_bGate valve 30 of the first embodiment_aThe differences are as follows: a longitudinal guide hole 38 is formed in the gate valve body 31 along the longitudinal direction of the gate valve.

In this embodiment, a gate valve cavity 36 opened upward (in the direction of the pressure fluid cavity) is also disposed on the gate valve body, and a longitudinal diversion hole 38 is disposed at the bottom of the gate valve cavity 36 and near one side of the high pressure cavity.

It should be noted that the longitudinal pilot bore is inclined at the bottom of the gate valve chamber 36, on the side adjacent the high pressure chamber, in order to accommodate the cylindrical roller. The inclination angle is between 10 degrees and 80 degrees.

It should be clear to those skilled in the art that the present disclosure is not limited thereto, and in other embodiments of the present disclosure, in the case that there is no gate valve cavity on the gate valve, the longitudinal diversion hole may also be directly opened on the gate valve along the longitudinal direction, without affecting the implementation of the present disclosure.

Regarding the cross-sectional shape of the longitudinal diversion holes, the cross-sectional shape can be circular, oval, rectangular, etc. The hydraulic diameter, number, position, etc. of the longitudinal diversion holes can be referred to the description of the first embodiment, and will not be repeated here.

When the gate valve of this embodiment is in operation, the high-pressure fluid in the pressure fluid chamber above the gate valve body first flows into the gate valve chamber 36, and then flows downwards along the longitudinal diversion hole 38, so as to wash out the viscous medium adhered to the bottom of the gate valve body 31.

As previously mentioned, the presence or absence of the cylindrical roller 33 does not affect the implementation of the present disclosure. In other embodiments of the present disclosure, no cylindrical rollers are provided. Fig. 3 is a schematic structural diagram of a gate valve according to an embodiment of the present disclosure without a cylindrical roller.

Referring to fig. 3, the cylindrical rollers are not provided at the positions where the lower portions of the gate valves contact the corresponding rotor assemblies.

When the gate valve works, high-pressure fluid in the pressure fluid cavity above the gate valve body firstly flows into the gate valve cavity, then is guided to the side face, facing the high-pressure cavity, of the gate valve body through the lateral guide holes 38 'and flows along the lateral guide grooves 37', so that viscous media adhered to the side face are washed clean, and the washing effect is further enhanced.

Fifth, first embodiment of Gate valve System

According to another aspect of the present disclosure, a gate valve system is also provided.

In a fifth exemplary embodiment of the present disclosure, a gate valve system is provided based on the gate valve of the first embodiment of the gate valve. Fig. 6A is a cross-sectional view of a gate valve system in a gate valve reset assembly position in accordance with an embodiment of the present disclosure. FIG. 6B is a cross-sectional view of the gate valve system of FIG. 6A in a non-gate valve reset assembly position.

As shown in fig. 6A and 6B, the gate valve system of the present embodiment includes: a pressure fluid chamber 11, a back pressure chamber 14, a gate valve returning mechanism 40, and the gate valve 30a of the first embodiment of the gate valve.

The pressure fluid chamber 11 is located at the gate valve 30_aOutside of (a). A back pressure chamber 14 is located outside the pressure fluid chamber 11 and supplies a continuous pressure fluid to the pressure fluid chamber 11.

The pressure fluid chamber 11 receives continuous pressure fluid from the back pressure chamber 14 to the gate valve 30_aA force is applied towards the inside of the cylinder. The diversion trench 37 communicates the pressure fluid cavity 11 with the high-pressure chamber a, fluid can flow in the diversion trench 37 rapidly, and the viscous medium adhered to the side surface of the gate valve 30a is washed clean; at the same time, the fluid in the pressure fluid chamber 11 can be quickly replenished or discharged.

To avoid the problem that the gate valve does not work properly due to lack of pressure of the fluid in the chamber during the initial operation of the rotating device, a gate valve reset assembly 40 is provided in the rotating device.

The pressure fluid chamber 11 is located inside the gate valve returning mechanism 40, and the back pressure chamber 14 is located outside the gate valve returning mechanism 40. The pressure fluid in the back pressure chamber may be filled into the pressure fluid chamber 11 through a void or a dedicated fluid flow hole of the gate valve reset assembly 40 itself.

Sixth, embodiment of the rotating device

According to another aspect of the present disclosure, a rotating device is also provided.

In a sixth exemplary embodiment of the present disclosure, based on the first embodiment of the gate valve system, a rotating device is proposed. Referring to fig. 6A and fig. 6B, the rotating device of the present embodiment includes:

a cylinder body 10 which encloses a cylindrical inner cavity, a gate valve groove is arranged on the inner side of the cylinder body along the central axis direction of the cylindrical inner cavity, and a pressure fluid cavity 11 is arranged on the outer side of the gate valve groove;

a main shaft at least partially located within the cylindrical cavity, a central axis of the main shaft coinciding with a central axis of the cylindrical cavity;

a rotor assembly 20 sleeved on the part of the main shaft positioned in the cylindrical inner cavity, and forming an axially extending sealed working space by rotating in the cylindrical inner cavity;

gate valve 30_aAt least a partial area of the upper surface thereof is exposed to the pressure fluid chamber 11, and the pressure fluid in the pressure fluid chamber 11 is supplied to the gate valve 30_aApplying a force towards the inside of the cylinder, pressing the distal end of the gate valve against the rotor assembly 20; meanwhile, part of the pressure fluid flows down along the diversion trench 37 on the side surface of the gate valve body, so that the viscous medium adhered to the side surface of the gate valve body is washed clean.

In addition, the side surface of the gate valve body is provided with a flow guide groove, or a longitudinal flow guide hole is arranged in the gate valve body along the longitudinal direction, and the fluid in the pressure fluid cavity can be rapidly discharged or supplemented through the flow guide groove or the flow guide hole, so that the rapid movement of the gate valve is greatly facilitated.

The respective components of the rotating device using the gate valve system according to the present embodiment will be described in detail below.

The cylinder 10 includes a cylinder body and front/rear end caps, which together define a cylindrical cavity. The cylindrical inner cavity is the working area of the rotating device of the embodiment.

The main shaft is rotatably and radially positioned and supported by a front sealing end cover and a rear sealing end cover in the cylinder body, and the central axis of the main shaft is superposed with the central axis of the cylindrical inner cavity. The main shaft transmits torque between the outside and the inside of the cylindrical inner cavity, taking a fluid motor as an example, the movement of fluid in the cylindrical inner cavity is converted into the torque on the main shaft, the main shaft transmits the torque to the outside of the cylindrical inner cavity, taking a compressor as an example, the main shaft transmits the torque input by an external power source to the cylindrical inner cavity to drive the rotor assembly to move.

In the present embodiment, the rotor assembly 20 is an eccentric rotor assembly. The eccentric rotor assembly includes: the eccentric crankshaft is sleeved on the part of the main shaft, which is positioned in the cylindrical inner cavity, and the central axis of the eccentric crankshaft is parallel to the central axis of the main shaft and staggered by a preset distance; the rolling piston wheel is sleeved on the eccentric crankshaft, the central axis of the rolling piston wheel is superposed with the central axis of the eccentric crankshaft, and the rolling piston wheel rolls along the inner cylindrical surface of the cylinder body to form a crescent sealed working space.

It should be noted that although the present embodiment employs an eccentric rotor type rotor assembly, the present invention is also applicable to a star rotor assembly. This star revolves formula rotor subassembly includes: a central sun gear drum and a planetary piston wheel. The central sun wheel roller is sleeved on the main shaft, an annular piston space is formed by the outer cylindrical surface of the central sun wheel roller and the inner cylindrical surface of the cylinder body, and two sides of the annular piston space are sealed. A cylindrical planetary piston wheel is arranged in the annular piston space in a rolling mode, and at least one end of the two ends of the planetary piston wheel, which extend out of the annular piston space, is connected to the main shaft through a connecting piece.

A gate valve groove is formed in a preset position on the inner side of the cylinder body along the central axis direction of the cylindrical inner cavity so as to accommodate the gate valve in a withdrawing state. The shape of the gate valve recess corresponds to the shape of the gate valve. If the gate valve is plate-shaped, the gate valve recess is also correspondingly plate-shaped. If the gate valve is strip-shaped, the gate valve groove is also correspondingly strip-shaped. In this embodiment, the gate valve 30_aThe gate valve groove is also in a corresponding strip shape.

At the gate valve 30_aIn the case where the gate valve recess is not completely sealingly engaged, there will be a situation where the pressure fluid in the pressure fluid chamber 11 passes through the gate valve recess and the gate valve 30_aThe gap between them leaks into the sealed working space, resulting in the risk of failure of the gate valve drive. In order to avoid the above risks, referring to fig. 6B, sealing grooves are further formed in the middle of the gate valve groove at positions on two sides of the gate valve groove in a normal direction. In which the sealing strip 34 is mounted. No matter the gate valve is in the withdrawing state or the extending state, the sealing strip is always tightly attached to the gate valve 30_aThereby completely isolating the pressure fluid chamber 11 from the sealed working space.

There is a pressurized fluid within the pressurized fluid chamber 11. The upper part of the gate valve projects into this pressure fluid chamber 11, the upper surface of which is subjected to the pressure of the pressure fluid against it towards the inside of the cylindrical interior. The pressure forces the end of the gate valve against the outer surface of the rotor assembly and continuously switches between a retracted state and an extended state: in the retracted state, it is retracted into the gate valve recess; in the extended state, it divides the axially extending sealed working space into two variable volume piston spaces-a high pressure chamber a and a low pressure chamber B.

A reset component mounting hole is arranged on the cylinder body at the radial outer side of the pressure fluid cavity 11. The reset assembly mounting hole is arranged at the left-right symmetrical position on the cylinder body, so that the force exerted on the gate valve by the gate valve reset assembly in the reset assembly mounting hole is left-right symmetrical and cannot incline towards one side.

In the reset assembly mounting hole, a gate valve reset assembly 40 is provided. The gate valve returning assembly 40 applies a returning force toward the inside of the cylinder to the gate valve 30 so that the gate valve 30 can press the outer surface of the rotor assembly as well in the case where the pressure fluid chamber 11 does not apply pressure to the gate valve 30. The gate valve reset assembly 40 may be referred to the above embodiments of the gate valve system and will not be repeated here.

A cover 50 opened downward is fixed to the outside of the cylinder body in a sealing manner above the return block mounting holes. The gland 50 may be sealed with the cylinder by an O-ring seal, a copper gasket seal, or the like.

The gland 50 defines a back pressure chamber 14 therebelow. The gland is provided with the fluid line connection port 11a described above. The back pressure chamber 14 passes through the pipe connection 11a and the corresponding fluid passage to the high pressure chamber a toward the outside. The high-pressure chamber a serves as a pressure fluid supply source.

The pressure fluid chamber 11 is connected to the high pressure chamber a. During operation, the medium in the pressure fluid cavity 11 flows to the high-pressure chamber a through the diversion trench 37, so that the viscous medium adhered to the side surface of the gate valve body 31 is washed clean, and meanwhile, the viscous medium adhered to the bottom of the gate valve body 31 also has a certain washing effect.

During operation, viscous oil is accumulated in the back pressure cavity 14 and the high pressure cavity A and in a flow passage between the back pressure cavity and the high pressure cavity A, so that the normal movement of the gate valve is prevented, and after the diversion trench is added, fluid in the pressure fluid cavity can be rapidly discharged or supplemented through the diversion trench, so that the gate valve has great benefits on the rapid movement of the gate valve.

It will be clear to a person skilled in the art that, instead of constructing the rotating means on the basis of the first embodiment of the gate valve system, it is also possible to construct the gate valve system and thus the rotating means on the basis of the second, third and fourth embodiments of the gate valve, and that the present disclosure is equally applicable.
