Description

Technical Field

[0001] This utility model relates to the field of valves, and more particularly to a double V-port balancing valve. Background Technology

[0002] During the commissioning of the primary and secondary heating networks, when the pressure difference between nearby users is large, using existing valves for throttling often results in a single valve being unable to overcome the excessive pressure difference. Closing and opening the valves causes drastic changes in flow rate, making it difficult to achieve the required flow rate. This is also accompanied by increased valve noise. As a last resort, it is necessary to close two valves on the inlet device to throttle the flow and increase the pressure difference, thereby reducing noise and complicating regulation.

[0003] Currently, in order to improve the above problems, simple ball-type W-type valves and V-type valves have been developed for regulation. However, since one side of the ball valve is the flow diameter or the valve has an inherent necking, the flow section is open, which is a one-sided regulation. Often, even when the valve is closed to the minimum, the required pressure difference cannot be formed.

[0074] The balance valve structure can be any of the following:

[0075] Option A: Includes a V-port balancing valve core, which is a spherical valve core that can be placed in the valve body. The valve core has an opening on one side, which is a valve opening with one side larger than the other. A rotating shaft position 2 is arranged on the valve core. A circular opening 9 is arranged on the other side of the valve core. A valve seat V-port 6 is also arranged on the valve seat. The valve seat 5 is made of PTFE and is located in the channel 7.

[0076] Option B: The balance valve core has circular openings 9 on both sides, and valve seat V ports 6 are arranged on the valve seats on both sides of the valve core. The valve seats 5 are made of PTFE and are located in the channel 7.

[0078] This embodiment is a higher-level solution. In subsequent solution settings, the tube seats at both ends of the ball are simultaneously closed, with a V-shaped opening or a V-shaped opening on one end on the valve seat and a V-shaped opening on the stainless steel ball at the other end. During adjustment, the V-shaped openings simultaneously increase or decrease, which is equivalent to adjusting with two V-shaped valves.

[0079] Example 2: As a further improvement, parallel, or optional independent solution, the valve port with one side larger and the other side smaller has a V-shaped structure. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: This embodiment defines a V-shaped structure because the specific port structure is not a standard V shape, but a similar shape.

[0080] Example 3: As a further improvement, parallel, or optional independent solution, the edge of the valve port, which is larger on one side and smaller on the other, is arc-shaped. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the arc-shaped lines facilitate fluid flow.

[0081] Example 4: As a further improvement, parallel, or optional independent solution, when ports are arranged on both sides of the valve core, the ports on both sides are symmetrically arranged on the valve core. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: complete symmetry, achieving synchronous adjustment.

[0082] Example 5: As a further improvement, parallel solution, or optional independent solution, when a V-port is arranged on one side of the valve core, a circular opening 9 is arranged on the other side of the valve core; a valve seat V-port 6 is also arranged on the valve seat, and the valve seat 5 is made of PTFE material and is located in the channel 7. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the valve seat 5 can be installed in the valve body.

[0083] Example 6: As a further improvement, parallel solution, or optional independent solution, the valve core is made of stainless steel. The substantive technical effect and implementation process of the technical solution described herein, i.e., its basic function, are as follows: similar materials are all within the scope of protection of this patent.

[0084] Example 7: As a further improvement, parallel, or optional independent solution, the V-port balance valve core is arranged in the channel 7 of the valve body, and the handle 8 is inserted into the rotating shaft position 2. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the handle 8 can also be replaced by an electric device to realize automatic valve control.

[0085] Example 8: As a further improvement, parallel, or optional independent solution, when the handle 8 is turned, the V-shaped port increases or decreases simultaneously, which is equivalent to the adjustment of two V-shaped valves; the V-shaped port here refers to the V-shaped port on the valve core and / or the V-shaped port 6 on the valve seat.

[0086] Example 9: As a further improvement, parallel, or optional independent solution, the valve seat 5 includes all mating surfaces, the mating surfaces of which fit one side of the circular opening 9 of the V-port balance valve core, and the valve seat 5 is waterproofed in the channel 7 by installing a waterproof gasket at the sealing ring position 11.

[0087] Compared to the ordinary one, the Kv value of the dual V-port balance valve is higher.

[0088] Table 1 and Figure 5 The flow rates are measured for a standard W valve and a double V valve at different Kv values, with the valve having a diameter of DN50.

[0089] Kv value explanation: When the pressure difference across the valve is 10 meters, the flow rate at different opening degrees.

[0090]

[0091] The second curve is the Kv value (m³ / h) curve of a normal W valve, and the first curve is the Kv value (m³ / h) curve of the dual V-port balance valve of this patent.

[0092] It can be seen that: the first curve shows a gradual increase in flow rate under various opening degrees, while the second curve shows a rapid increase in flow rate when the valve opening is 60%. That is, when the opening is 60-100%, the flow rate increases from 10 m³ / h to 48.1 m³ / h, indicating poor valve regulation performance.

[0093] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
