Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic Taylor valves, and in particular relates to a ceramic Taylor valve with an auxiliary check device. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] The existing Chinese patent number CN219013438U discloses a wear-resistant Taylor valve, including a top valve body, the top of the top valve body is fixedly connected with a discharge pipe, the bottom of the top valve body is welded with a top plate, and the bottom of the top plate is provided with a sealing assembly, the bottom of the top plate is bolted with a bottom plate, and the bottom of the bottom plate is fixedly connected with a bottom valve body, and the bottom of the bottom valve body is fixedly connected with a first feed pipe. The wear-resistant Taylor valve is provided with a top plate, a sealing assembly, bolts, screw holes, nuts, a sealing groove, a sealing plate and a bottom plate. When the top plate is connected to the bottom plate, the sealing plate can be stuck in the sealing groove for sealing connection. At the same time, the top plate and the bottom plate can be fixed together by bolts, thereby strengthening the sealing effect of the top valve body with the bottom valve body. The sealing effect of the Taylor valve can be improved by two sealing methods, meeting people's daily use needs, bringing convenience to people's daily use, and improving the service life of the Taylor valve.

[0004] The above scheme has the following problems during implementation: the device can improve the protection effect of the valve core by the back and forth movement of the valve core. At the same time, the support pad and the clamping plate arranged in the first feed pipe and the second feed pipe can greatly improve the limiting effect of the valve core, which can meet people's daily needs for valve use, bring convenience to people's daily use, and extend the service life. However, during use, the feed pipe is only stopped by the valve core. When the water flow rate is low, the valve core cannot fall into the feed pipe in time, thereby failing to cut off the reflux channel in time, reducing the practicability of the device.

[0005] The utility model aims to provide a ceramic Taylor valve with an auxiliary check device to solve the technical problem proposed in the background technology that the flow of the feed pipe is stopped only by the valve core. When the water flow rate is low, the valve core cannot fall into the feed pipe in time, thereby failing to cut off the reflux channel in time. Utility Model Content

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a ceramic Taylor valve with an auxiliary check device, comprising a top valve body, the bottom of the top valve body is fixedly connected to the bottom of the bottom valve body, a sealing ball is arranged inside the top valve body, the bottom of the bottom valve body is fixedly connected to the water inlet end, a sealing valve seat is installed inside the water inlet end, and a check mechanism is arranged inside the sealing valve seat;

[0007] The check mechanism includes a fixed block fixedly connected to the inside of the sealing valve seat, the upper surface of the fixed block is rotatably connected to a double-plate sealing valve plate, two mounting blocks are fixedly connected to the front and rear sides of the upper surface of the double-plate sealing valve plate, a No. 2 bolt is threadedly connected between the two mounting blocks, a bearing is installed at the other end of the No. 2 bolt, and another No. 2 bolt is fixedly connected to the other end of the bearing, a return spring is fixedly connected to one end of the upper surface of the right plate of the double-plate sealing valve plate, the other end of the return spring is fixedly connected to one end of the upper surface of the left plate of the double-plate sealing valve plate, and the return spring is sleeved on the outer surface of the No. 2 bolt.

[0008] Preferably, a water outlet end is fixedly connected to the top of the top valve body.

[0009] Preferably, a wear-resistant layer is installed on the inner wall of the top valve body, and the wear-resistant layer is made of wear-resistant structural ceramic material.

[0010] Preferably, the top valve body and the bottom valve body are fixedly connected by a plurality of No. 1 bolts, and two nuts are threadedly connected to the outer surface of the No. 1 bolts, and the two nuts are respectively arranged on the top of the top valve body and the lower surface of the bottom valve body.

[0011] Preferably, two check mechanisms and water inlet ends are provided, and the two check mechanisms and water inlet ends are symmetrically arranged on the left and right sides of the lower surface of the bottom valve body relative to the center position of the bottom valve body.

[0014] Preferably, the sealing surface in the non-return mechanism is spray-welded with wear-resistant hard alloy.

[0015] The utility model discloses a ceramic Taylor valve of an auxiliary check device, which has the following advantages: the ceramic Taylor valve of the auxiliary check device drives the sealing ball to leave the sealing valve seat through the pressure generated by the water flow. Since the water inlet end of the valve is connected to the pump, the pressure is unstable during the operation of the pump, and the medium cannot maintain a stable pressure flow. When the pressure of the medium is reduced, the double-plate sealing valve plate is driven to return to the seal quickly through the deformation of the return spring, and the double-plate sealing valve plate is driven to flip and reset quickly, thereby cutting off the reflux channel and effectively preventing the fluid from flowing back. The check mechanism cooperates with the sealing ball to further assist in stopping the flow of the fluid, thereby improving the flow stopping effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] In order to better understand the purpose, structure and function of the utility model, the ceramic Taylor valve of the auxiliary check device of the utility model is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4As shown, a ceramic Taylor valve with an auxiliary check device of the utility model comprises a top valve body 1, a bottom valve body 7 is fixedly connected to the bottom of the top valve body 1, a sealing ball 9 is arranged inside the top valve body 1, and the sealing ball 9 can block the backflow of the fluid, and the bottom of the bottom valve body 7 is fixedly connected to the water inlet end 3, and the water flows into the water inlet end 3, and a sealing valve seat 5 is installed inside the water inlet end 3, and a check mechanism is arranged inside the sealing valve seat 5, and the check mechanism assists the sealing ball 9 to stop the flow of the fluid;

[0029] The check mechanism includes a fixed block 6 fixedly connected to the inside of the sealing valve seat 5, the upper surface of the fixed block 6 is rotatably connected to a double-plate sealing valve plate 8, two mounting blocks 13 are fixedly connected to the front and rear sides of the upper surface of the double-plate sealing valve plate 8, a No. 2 bolt 15 is threadedly connected between the two mounting blocks 13, a bearing 14 is installed at the other end of the No. 2 bolt 15, and another No. 2 bolt 15 is fixedly connected to the other end of the bearing 14, a return spring 12 is fixedly connected to one end of the upper surface of the right plate of the double-plate sealing valve plate 8, and the other end of the return spring 12 is fixedly connected to one end of the upper surface of the left plate of the double-plate sealing valve plate 8, and the return spring 12 is sleeved on the outer surface of the No. 2 bolt 15;

[0030] When the pressure generated by the water flow is greater than the gravity of the sealing ball 9, the pressure generated drives the sealing ball 9 to leave the sealing valve seat 5 and roll along the inclined surface to the sealing valve seat 5 of the other water inlet end 3, and the pressure generated by the water flow drives the two valve plates of the double-plate sealing valve plate 8 to flip upward on both sides, thereby driving the mounting block 13 to rotate on the second bolt 15. At this time, the return spring 12 is deformed to facilitate the flow of water;

[0031] When the pressure of the water flow is less than the gravity of the sealing ball 9, the sealing ball 9 falls back to the initial sealing valve seat 5 with the refluxed liquid, and the return spring 12 recovers its deformation to drive the double-plate sealing valve plate 8 to reset and move. When the fluid refluxes, the reflux channel is cut off, thereby preventing the backflow. The non-return mechanism assists in stopping the flow of the fluid, thereby improving the flow-stopping effect of the device.

[0032] like Figure 1-3 As shown, a water outlet 2 is fixedly connected to the top of the top valve body 1 , and water flows in through the water inlet 3 and out of the water outlet 2 through a check mechanism.

[0033] like Figure 2-3 As shown, a wear-resistant layer 4 is installed on the inner wall of the top valve body 1. The wear-resistant layer 4 is made of wear-resistant structural ceramic material. The sealing ball 9 moves in the top valve body 1, and the force generated by the water flow on the flow in the top valve body 1, the wear-resistant layer 4 can protect the top valve body 1, thereby increasing the service life of the device.

[0034] like Figure 1-3As shown, the top valve body 1 and the bottom valve body 7 are fixedly connected by a plurality of No. 1 bolts 10, and two nuts 11 are threadedly connected to the outer surface of the No. 1 bolts 10, and the two nuts 11 are respectively arranged on the top of the top valve body 1 and the lower surface of the bottom valve body 7. When in use, the bottom of the top valve body 1 and the top of the bottom valve body 7 are first fixedly installed by the No. 1 bolts 10 and the nuts 11.

[0035] like Figure 2-4 As shown, two check mechanisms and water inlet ends 3 are provided, and the two check mechanisms and water inlet ends 3 are symmetrically arranged on the left and right sides of the lower surface of the bottom valve body 7 relative to the center position of the bottom valve body 7. When the pressure generated by the water flow is greater than the gravity of the sealing ball 9, the generated pressure drives the sealing ball 9 to leave the sealing valve seat 5 and roll along the inclined surface to the sealing valve seat 5 of the other water inlet end 3.

[0036] like Figure 2-3 As shown, the sealing valve seat 5 is made of rubber material, and the inner lining of the sealing valve seat 5 is wear-resistant structural ceramics. The sealing ball 9 moves between the two sealing valve seats 5, and the wear-resistant structural ceramics can protect the sealing valve seat 5.

[0037] like Figure 2-3 As shown, the sealing ball 9 is made of a combination of a metal frame and rubber, and the diameter of the sealing ball 9 is larger than the diameter of the sealing valve seat 5, so as to avoid the diameter of the sealing ball 9 being smaller than the diameter of the sealing valve seat 5, prevent the sealing ball 9 from being stuck in the sealing valve seat 5, and prevent the sealing ball 9 from being unable to block the reflux channel.

[0038] like Figure 2-4 As shown, the sealing surface in the non-return mechanism is spray-welded with wear-resistant hard alloy, so that the non-return mechanism has better wear resistance.

[0039] Working principle of the ceramic Taylor valve with auxiliary check device:

[0040] The medium enters from one of the water inlet ends 3 of the bottom valve body 7, pushes open the double-plate sealing valve plate 8, and then pushes open the sealing ball 9, and the sealing ball 9 moves into the other water inlet end 3. As the medium continues to enter, it pushes the sealing ball 9 to seal the other water inlet end 3, and then the medium flows into the process pipeline from the water outlet end 2 at the upper end of the top valve body 1.

[0041] Since the water inlet end 3 of the valve is connected to a pump, the pressure is unstable during the operation of the pump and the medium cannot maintain a stable pressure flow. When the pressure of the medium decreases, the double-plate sealing valve plate 8 is quickly returned to the seal through the deformation of the return spring 12, which can effectively block the backflow of the medium.

[0042] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
