[0003] The current flow regulating pressure regulating valve is mostly one-way sealing structure, and needs to be installed in a specific direction to ensure sealing effect during installation.The flow regulating pressure regulating valve with one-way sealing structure only allows medium to flow in one direction, so the use scene of the flow regulating pressure regulating valve with one-way sealing structure is relatively single, and only one sealing structure is used during use, so the sealing effect is poor. UTILITY MODEL CONTENT

[0004] The utility model aims at the defects and deficiencies of prior art, and provides a hydraulic transmission bidirectional sealing flow regulating pressure regulating valve.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hydraulic transmission bidirectional sealing flow regulating pressure regulating valve, comprising a valve body, a water inlet and a water outlet opened on the valve body, a communication port opened on the valve body between the water inlet and the water outlet and connected with the water inlet and the water outlet respectively, a fixed column arranged in the communication port on the valve body, two sealing rings arranged on the valve body between the water inlet and the water outlet and the communication port respectively, two sealing plates horizontally movably arranged on the left and right sides of the fixed column, a driving device arranged between the fixed column and the two sealing plates, an inclined taper surface arranged on the two sealing plates respectively and close to the sealing ring, and a buffer mechanism arranged on the two sealing plates respectively.

[0006] Further improvement: the driving device comprises two fixed sleeves arranged on the left and right sides of the fixed column respectively, hydraulic cavities opened on the fixed column and the fixed sleeves respectively, driving rods fixedly arranged on the two sealing plates at one end and slidably matched with the two fixed sleeves at the other end, sealing members arranged between the driving rods and the fixed sleeves, a hydraulic system arranged on the valve body and connected with the hydraulic cavities, and a plurality of reset springs arranged on the left and right sides of the two sealing plates and the fixed column respectively.

[0007] Further improvements are that the sealing member comprises two sealing hydraulic plates respectively slidably arranged in two fixed sleeves and fixedly connected with two driving rods, sealing hydraulic rings respectively arranged on the circumferential sides of the two sealing hydraulic plates, and sealing ring grooves respectively formed on the two fixed sleeves and located on the outer circumferential sides of the sealing hydraulic plates.

[0008] Further improvements are that the buffer mechanism comprises two buffer grooves respectively formed on the two sealing plates, a plurality of buffer plates respectively arranged on the two sealing plates in the buffer grooves, hinged rods respectively arranged between one end of each buffer plate and the sealing plate, and elastic members respectively arranged between the other end of each buffer plate and the sealing plate and located in the buffer grooves.

[0009] Further improvements are that the elastic member comprises a fixed block fixedly arranged on the sealing plate in the buffer groove, an inclined elastic web plate arranged on the other end of the fixed block and connected with the other end of the buffer plate, a tapered deformation zone formed between the fixed block and the inclined elastic web plate, and an elastic reset member arranged between the fixed block and the inclined elastic web plate and located in the tapered deformation zone.

[0010] Further improvements are that the elastic reset member is an arc-shaped elastic plate fixedly arranged between the fixed block and the inclined elastic web plate and located in the tapered deformation zone, and the arc-shaped elastic plate is a rubber plate.

[0011] Further improvements are that the elastic reset member is an arc-shaped spring fixedly arranged between the fixed block and the inclined elastic web plate and located in the tapered deformation zone.

[0012] After the above technical scheme is adopted, the beneficial effects of the present application are that when it is necessary to control the two sealing plates to seal the water inlet and the water outlet, the two sealing plates are controlled by the driving device to approach or move away from the two sealing rings, so that the water inlet and the water outlet are simultaneously sealed or opened, the bidirectional sealing effect can be achieved, the valve body does not need to be installed in a specific direction during installation, and the medium is allowed to flow in the valve body in the reverse direction, the use scenarios are more diverse, the sealing effect is better than that of the unidirectional sealing structure, and when the medium flows, the buffer mechanism can buffer the rapidly flowing medium to reduce the occurrence of water hammer effect.

[0013] Further effects are that when the medium is pressed on the buffer plate, the buffer plate rotates around the hinged rod towards the fixed block, so as to extrude the inclined elastic web plate to produce elastic deformation towards the tapered deformation zone, thereby buffering the impact of the buffer plate, and when the medium is no longer in contact with the buffer plate, the elastic reset member pushes the inclined elastic web plate to reset.

[0014] Further effects: when the two sealing plates need to seal the water inlet and the water outlet, the hydraulic oil is pushed into the hydraulic cavity by the hydraulic system, the hydraulic oil enters the fixed sleeve and pushes the driving rod to move outward, thereby driving the two sealing plates to move close to the two sealing rings, the reset spring is stretched to gradually generate elastic potential energy, until the inclined conical surface is pressed against the two sealing rings, thereby sealing the water inlet and the water outlet through the cooperation of the sealing ring and the sealing plate; if the two sealing plates need to control the water inlet and the water outlet to flow, the hydraulic oil is withdrawn by the hydraulic system, at this time, as the hydraulic oil in the hydraulic cavity decreases, the reset spring gradually releases the elastic potential energy, driving the two sealing plates to move away from the two sealing rings, so that the medium can flow in the water inlet and the water outlet.

[0015] Further effects: when the hydraulic oil enters or leaves the fixed sleeve, the two sealing hydraulic plates slide in the fixed sleeve, and are pressed in the sealing ring groove and the circumferential side of the sealing hydraulic plate through the sealing hydraulic ring, so that the sealing hydraulic plate seals the gap between the sealing ring groove and the sealing hydraulic plate during movement, reducing the phenomenon of hydraulic oil leakage.

DETAILED DESCRIPTION

[0023] The utility model is further explained in connection with the drawings and specific embodiments.

[0024] Reference Figures 1 to 5 The technical scheme adopted by the specific embodiment is shown in the drawings: a hydraulic transmission bidirectional sealing flow and pressure regulating valve, comprising a valve body 1, a water inlet 2 and a water outlet 3 arranged on the valve body 1, a communication port 4 arranged on the valve body 1 between the water inlet 2 and the water outlet 3 and connected with the water inlet 2 and the water outlet 3 respectively, a fixed stand column 5 arranged on the valve body 1 in the communication port 4, two sealing rings 51 arranged on the valve body 1 between the water inlet 2 and the water outlet 3 and the communication port 4 respectively, two sealing plates 6 arranged on the left and right sides of the fixed stand column 5 respectively and capable of moving horizontally, a drive device arranged between the fixed stand column 5 and the two sealing plates 6, an inclined conical surface 22 arranged on each of the two sealing plates 6 and close to the end of the sealing ring 51, and a buffer mechanism arranged on each of the two sealing plates 6. The fixed stand column 5 is arranged at the center of the valve body 1. The sealing ring 51 is a rubber ring, which is embedded or fixed by adhesive on the valve body 1.

[0025] The drive device comprises two fixed sleeves 7 arranged on the left and right sides of the fixed stand column 5 respectively, hydraulic cavities 8 arranged on the fixed stand column 5 and the fixed sleeves 7 respectively, drive rods 9 fixed on the two sealing plates 6 respectively at one end and slidably connected with the two fixed sleeves 7 at the other end, sealing members arranged between the drive rods 9 and the fixed sleeves 7, a hydraulic system 10 arranged on the valve body 1 and connected with the hydraulic cavities 8, and a plurality of reset springs 11 arranged on the left and right sides of the two sealing plates 6 and the fixed stand column 5 respectively. The hydraulic system 10 is composed of a hydraulic element (a hydraulic oil pump), a hydraulic control element (various hydraulic valves), a hydraulic execution element (a hydraulic cylinder and a hydraulic motor, etc.), a hydraulic auxiliary part (a pipeline and an accumulator, etc.), and hydraulic oil, which is a common knowledge and will not be described here. There are at least two reset springs 11 on each sealing plate 6, and the two reset springs 11 are symmetrically arranged on the upper and lower sides or the left and right sides of the fixed sleeve 7. If the number of reset springs 11 is more than two, the plurality of reset springs 11 are arranged annularly and equidistantly around the fixed sleeve 7 as the central axis. The reset spring 11 is a tensile spring.

[0026] The sealing member comprises two sealing hydraulic plates 12 respectively slidably arranged in two fixed sleeves 7 and fixedly connected with two driving rods 9, sealing hydraulic rings 13 respectively arranged on the circumferential sides of the two sealing hydraulic plates 12, and sealing ring grooves 14 respectively formed on the two fixed sleeves 7 and located on the outer circumferential sides of the sealing hydraulic plates 12.

[0027] The buffer mechanism comprises two buffer grooves 15 respectively formed on the two sealing plates 6, a plurality of buffer plates 16 respectively arranged on the two sealing plates 6 in the buffer grooves 15, hinged rods 17 respectively arranged between one end of each of the buffer plates 16 and the sealing plates 6, and elastic members respectively arranged between the other end of each of the buffer plates 16 and the sealing plates 6 and located in the buffer grooves 15. The buffer plates 16 are arranged obliquely on the sealing plates 6. In this application, there are six buffer plates 16 on each sealing plate 6. The six buffer plates 16 are divided into two groups, each group comprising three buffer plates 16. The two groups of buffer plates 16 are symmetrically arranged above and below the sealing plates 6. The two groups of buffer plates 16 are symmetrically arranged above and below the midpoint of the sealing plates 6. Since the medium flows in the direction of the sealing ring 51 and the inclined conical surface 22 when being conveyed, the medium also spreads around the midpoint of the sealing plate 6 when contacting the buffer plate 16. At this time, the two groups of buffer plates 16 symmetrically arranged above and below can buffer the spreading medium. Compared with the direct equidistant arrangement of six buffer plates 16, the symmetrically arranged buffer plates 16 can buffer the medium according to the flow direction, thereby improving the buffering effect on the medium.

[0028] The elastic member comprises a fixed block 18 fixedly arranged on the sealing plate 6 in the buffer groove 15, an inclined elastic web 19 arranged at the other end of the fixed block 18 and connected with the other end of the buffer plate 16, a conical deformation zone 20 formed between the fixed block 18 and the inclined elastic web 19, and an elastic reset member 21 arranged between the fixed block 18 and the inclined elastic web 19 and located in the conical deformation zone 20.

[0029] The material of the fixed block 18 can be the same as that of the inclined elastic web 19, which is an elastic material such as rubber, PU or TPU. The number of the fixed block 18 and the inclined elastic web 19 is the same as that of the buffer plate 16, and the arrangement position and direction are set according to the arrangement of the buffer plate 16.

[0030] The elastic reset member 21 is an arc-shaped elastic plate fixedly arranged between the fixed block 18 and the inclined elastic web 19 and located in the conical deformation zone 20. The arc-shaped elastic plate is a rubber plate.

[0031] The elastic reset member 21 is an arc spring fixed between the fixed block 18 and the inclined elastic connecting plate 19 and located in the conical deformation area 20.

[0032] The working principle of the utility model is: when it is needed to control the two sealing plates 6 to seal the water inlet 2 and the water outlet 3, the two sealing plates 6 are controlled to move close to or away from the two sealing rings 51 by the driving device, so that the water inlet 2 and the water outlet 3 are simultaneously sealed or opened, the bidirectional sealing effect can be realized, the sealing plates 1 do not need to be installed in a specific direction during installation, the medium is allowed to flow reversely in the valve body 1, the use scene is more diverse, the sealing effect is better than that of the unidirectional sealing structure, and when the medium flows, the buffer mechanism can buffer the rapidly flowing medium, reducing the occurrence of water hammer effect.

[0033] When the medium is stamped on the buffer plate 16, the buffer plate 16 rotates around the hinge rod 17 to the direction of the fixed block 18, so as to extrude the inclined elastic connecting plate 19 to generate elastic deformation to the conical deformation area 20, thereby buffering the impact of the buffer plate 16, and when the medium is no longer in contact with the buffer plate 16, the elastic reset member 21 pushes the inclined elastic connecting plate 19 to reset.

[0034] When it is needed to control the two sealing plates 6 to seal the water inlet 2 and the water outlet 3, the hydraulic oil is pushed into the hydraulic cavity 8 by the hydraulic system 10, the hydraulic oil enters the fixed sleeve 7 and pushes the driving rod 9 to move outward, so as to drive the two sealing plates 6 to move close to the two sealing rings 51, the reset spring 11 is stretched to gradually generate elastic potential energy, until the inclined conical surface 22 is extruded with the two sealing rings 51, so that the water inlet 2 and the water outlet 3 are sealed by the cooperation of the sealing ring 51 and the sealing plate 6; if it is needed to control the two sealing plates 6 to flow through the water inlet 2 and the water outlet 3, the hydraulic oil is withdrawn by the hydraulic system 10, at this time, with the decrease of the hydraulic oil in the hydraulic cavity 8, the reset spring 11 gradually releases the elastic potential energy, drives the two sealing plates 6 to move away from the two sealing rings 51, so that the medium can flow through the water inlet 2 and the water outlet 3.

[0035] When the hydraulic oil enters or leaves the fixed sleeve 7, the two sealing hydraulic plates 12 slide in the fixed sleeve 7, and are extruded in the sealing ring groove 14 and the circumferential side of the sealing hydraulic plate 12 through the sealing hydraulic ring 13, so that the sealing hydraulic plate 12 seals the gap between the sealing ring groove 14 and the sealing hydraulic plate 12 in the process of moving, reducing the phenomenon of hydraulic oil leakage.
