Abstract
Description
Technical Field
[0001] The utility model relates to a valve, in particular to a fluid valve and a valve group. Background Art
[0002] At present, solenoid valves are usually used for automatic on and off of fluid transportation. For fluids with lower viscosity, the current solenoid valves can meet the function of blocking or conducting fluid transportation, but for fluids with higher viscosity, the current solenoid valves cannot meet the usage requirements. For example, when it is necessary to conduct liquid transportation, the magnetic force provided by the solenoid valve cannot overcome the viscosity of the fluid to open the internal channel for fluid transportation, resulting in the inability to conduct fluid transportation. Therefore, there is an urgent need for a fluid valve with higher usage stability. Utility Model Content
[0003] The utility model aims to provide a fluid valve and a valve group to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve the technical problem is:
[0005] A fluid valve comprises: a valve body, which is provided with a blocking block inside, the blocking block divides the interior of the valve body into a liquid inlet chamber and a liquid outlet chamber, a connecting hole connected to the liquid inlet chamber and the liquid outlet chamber is provided in the middle of the blocking block, a liquid inlet hole is provided at the outer side of the valve body facing the liquid inlet chamber, and a liquid outlet hole is provided at the outer side of the valve body facing the liquid outlet chamber; a valve core is located in the liquid inlet chamber, the valve core is elastically pressed against the blocking block, and the valve core blocks the connecting hole; a telescopic driving member, which is drivingly connected to a push rod, the push rod is inserted into the liquid outlet chamber, and the telescopic driving member can drive the push rod to pass through the connecting hole and push the valve core away from the blocking block.
[0006] This technical solution has at least the following beneficial effects: during normal use, the valve core is pressed against the blocking block by the spring to block the connecting hole. At this time, the liquid inlet chamber and the liquid outlet chamber are separated from each other. When the fluid is input from the liquid inlet hole to the liquid inlet chamber, the fluid will not enter the liquid outlet chamber. At this time, the function of blocking and conveying the fluid can be realized. When the fluid needs to be output outward, the telescopic drive member drives the push rod to push the valve core away from the blocking block. At this time, the blocking block no longer blocks the liquid inlet hole. The fluid can pass through the connecting hole and flow into the liquid outlet chamber, and finally be output outward from the liquid outlet. At this time, the function of conducting and conveying the fluid can be realized. When the fluid needs to be blocked again, the telescopic drive member drives the push rod to retreat and reset, and the valve body is pressed against the blocking block again under the elastic force to block the connecting hole. In this way, the telescopic drive member is used to provide power from outside the valve body to conduct the inside of the valve body, thereby ensuring that the fluid can be conducted and conveyed. This is especially suitable for high-viscosity fluids and has strong working stability.
[0007] As a further improvement of the above technical solution, the valve body includes a sleeve, a connecting block and a liquid inlet head, the connecting block is connected to one end of the sleeve, the push rod passes through the connecting block, the blocking block is connected to the sleeve, the space in the sleeve between the connecting block and the blocking block forms the liquid outlet cavity, the liquid outlet hole is formed on the outside of the sleeve, one end of the liquid inlet head is connected to the other end of the sleeve, the liquid inlet cavity is formed at the end where the liquid inlet head is connected to the sleeve, a spring is arranged in the liquid inlet cavity, one end of the spring presses against the valve core, and the liquid inlet cavity is formed at the other end of the liquid inlet head. The connecting block can block one end of the sleeve and allow the push rod to pass through and extend into the sleeve. The blocking block is installed in the sleeve, thereby forming a liquid outlet cavity between the inside of the sleeve and the connecting block, and the liquid inlet cavity is formed in the liquid inlet head. The spring is located in the liquid inlet cavity, one end of which abuts against the inner bottom side of the liquid inlet cavity, and the other end abuts against the valve core, pushing the valve core toward the blocking block, thereby maintaining the blockage of the connecting hole. In this way, a spring with a large elastic coefficient can be directly configured in the liquid inlet cavity to provide sufficient elastic force to the valve core, thereby achieving a stable blocking seal for the fluid, further improving the applicability to fluids with higher viscosity.
[0008] As a further improvement of the above technical solution, the valve core includes a valve seat and a top ball, the spring is pressed against one side of the valve seat, the top ball is located on the other side of the valve seat, and the top ball blocks the communication hole. One end of the spring is pressed against the valve seat, and a force is applied to the top ball through the valve seat, and the top ball is used to block the end of the communication hole. The top ball can better adapt to the inner shape of the end of the communication hole, thereby improving the sealing effect of the end of the communication hole.
[0009] As a further improvement of the above technical solution, a limiting groove is provided on the side of the valve seat facing the top ball, and one side of the top ball abuts against the limiting groove. One side of the top ball is limited by the limiting groove, so that the top ball is better aligned with the connecting hole. When the top rod pushes the top ball away from the blocking block, the top ball is not easy to produce relative displacement with the blocking block, thereby improving the working stability.
[0010] As a further improvement of the above technical solution, a side of the valve seat away from the top ball is connected to a limiting column, and one end of the spring is sleeved outside the limiting column. The limiting column can be used to limit the end of the spring, which is beneficial to reduce the relative displacement between the end of the spring and the valve seat, and further improve the stability during operation.
[0011] As a further improvement of the above technical solution, one end of the liquid inlet head is threadedly connected to the sleeve. The liquid inlet head and the sleeve can be detached from each other, and the two can be tightly connected to each other through threads, which effectively improves the convenience of assembly and subsequent use and maintenance.
[0012] As a further improvement of the above technical solution, the connection block is threadedly connected in the sleeve. The connection block and the sleeve can be detached from each other, and the two can be tightly connected to each other through threads, which effectively improves the convenience of assembly and subsequent use and maintenance.
[0013] As a further improvement of the above technical solution, a sealing ring is provided between the push rod and the connecting block, which can improve the sealing between the position of the connecting block through which the push rod passes and the push rod, and is conducive to preventing the fluid from leaking out from between the push rod and the connecting block.

DETAILED DESCRIPTION
[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

[0023] Reference Figure 1 and Figure 2, a fluid valve, comprising: a valve body, a sealing block 11 is arranged inside the valve body, the sealing block 11 separates the inside of the valve body into a liquid inlet chamber and a liquid outlet chamber, a connecting hole 111 connected to the liquid inlet chamber and the liquid outlet chamber is arranged in the middle of the sealing block 11, a liquid inlet hole 141 is arranged on the outer side of the valve body facing the liquid inlet chamber, and a liquid outlet hole 121 is arranged on the outer side of the valve body facing the liquid outlet chamber; a valve core is located in the liquid inlet chamber, the valve core is elastically pressed against the sealing block 11, and the valve core blocks the connecting hole 111; a telescopic driving member 2, which is drivingly connected to a push rod 21, the push rod 21 is inserted into the liquid outlet chamber, and the telescopic driving member 2 can drive the push rod 21 to pass through the connecting hole 111 and push the valve core away from the sealing block 11.
[0024] In this fluid valve, during normal use, the valve core is pressed against the blocking block 11 by the spring 15 to block the communicating hole 111. At this time, the liquid inlet chamber and the liquid outlet chamber are separated from each other. When the fluid is input into the liquid inlet chamber from the liquid inlet hole 141, the fluid will not enter the liquid outlet chamber. At this time, the fluid blocking and conveying function can be realized. When the fluid needs to be output outward, the telescopic driving member 2 drives the push rod 21 to push the valve core away from the blocking block 11. At this time, the blocking block 11 no longer blocks the liquid inlet hole 141, and the fluid can pass through. The liquid passes through the connecting hole 111 and flows into the liquid outlet cavity, and is finally output from the liquid outlet hole 121. At this time, the fluid conduction and transportation function can be realized. When the fluid needs to be blocked again, the telescopic driving member 2 drives the push rod 21 to retreat and reset, and the valve body is pressed against the blocking block 11 again under the elastic force to block the connecting hole 111. In this way, the telescopic driving member 2 is used to provide power from outside the valve body to conduct the inside of the valve body, thereby ensuring that the fluid can be conducted and transported. This is especially suitable for high-viscosity fluids and has strong working stability.
[0025] The valve core is elastically pressed against the blocking block 11 in the valve body. An elastic block such as rubber can be installed on the valve core, and the elastic block provides an elastic force to press the valve core against the blocking block 11. In the present embodiment, the valve body comprises a sleeve 12, a connecting block 13 and a liquid inlet head 14. The connecting block 13 is connected to one end of the sleeve 12. The push rod 21 passes through the connecting block 13. The blocking block 11 is connected to the sleeve 12. The space between the connecting block 13 and the blocking block 11 in the sleeve 12 forms the liquid outlet cavity. The liquid outlet hole 121 is formed on the outside of the sleeve 12. One end of the liquid inlet head 14 is connected to the other end of the sleeve 12. The liquid inlet cavity is formed at the end where the liquid inlet head 14 is connected to the sleeve 12. A spring 15 is arranged in the liquid inlet cavity. One end of the spring 15 presses against the valve core. The liquid inlet cavity is formed at the other end of the liquid inlet head 14. The connecting block 13 can block one end of the sleeve 12 and allow the push rod 21 to pass through and extend into the sleeve 12. The blocking block 11 is installed in the sleeve 12, thereby forming a liquid outlet cavity between the inside of the sleeve 12 and the connecting block 13, and the liquid inlet cavity is formed in the liquid inlet head 14. The spring 15 is located in the liquid inlet cavity, one end of which abuts against the inner bottom side of the liquid inlet cavity, and the other end abuts against the valve core, pushing the valve core toward the blocking block 11, thereby maintaining the blockage of the connecting hole 111. In this way, a spring 15 with a large elastic coefficient can be directly configured in the liquid inlet cavity to provide sufficient elastic force to the valve core, thereby achieving a stable blocking seal for the fluid, further improving the applicability to fluids with higher viscosity.
[0026] The valve core can be a block structure, directly pressed against the blocking block 11 to block and block the connecting hole 111, and in order to improve the blocking effect of the connecting hole 111, in this embodiment, the valve core includes a valve seat 31 and a top ball 32, the spring 15 presses against one side of the valve seat 31, and the top ball 32 is located on the other side of the valve seat 31, and the top ball 32 blocks the connecting hole 111. One end of the spring 15 presses against the valve seat 31, and applies force to the top ball 32 through the valve seat 31, and the end of the connecting hole 111 is blocked by the top ball 32, and the top ball 32 can better adapt to the inner shape of the end of the connecting hole 111, thereby improving the sealing effect of the end of the connecting hole 111.
[0027] Furthermore, a limiting groove is provided on one side of the valve seat 31 facing the top ball 32, and one side of the top ball 32 abuts against the limiting groove. One side of the top ball 32 is limited by the limiting groove, so that the top ball 32 is better aligned with the connecting hole 111. When the top rod 21 pushes the top ball 32 away from the blocking block 11, the top ball 32 is not easy to produce relative displacement with the blocking block 11, thereby improving the working stability.
[0028] Furthermore, a side of the valve seat 31 away from the top ball 32 is connected to a limiting column 311, and one end of the spring 15 is sleeved outside the limiting column 311. The limiting column 311 can be used to limit the end of the spring 15, which is beneficial to reduce the relative displacement between the end of the spring 15 and the valve seat 31, and further improve the stability during operation.
[0029] The liquid inlet head 14 and the sleeve 12 may be detachably connected, and specifically, one end of the liquid inlet head 14 is threadedly connected to the sleeve 12. The liquid inlet head 14 and the sleeve 12 are mutually detachable, and the two can be tightly connected to each other through threads, which effectively improves the convenience of assembly and subsequent use and maintenance.
[0030] Similarly, the connection block 13 and the sleeve 12 may also be detachably connected, and the connection block 13 is threadedly connected in the sleeve 12. The connection block 13 and the sleeve 12 can be detachably connected to each other, and the two can be tightly connected to each other through threads, which effectively improves the convenience of assembly and subsequent use and maintenance.
[0031] In order to better fill the gap between the push rod 21 and the connection block 13, in this embodiment, a sealing ring is provided between the push rod 21 and the connection block 13. The sealing ring can improve the sealing between the position of the connection block 13 for the push rod 21 to pass through and the push rod 21, which is conducive to preventing the fluid from leaking out from between the push rod 21 and the connection block 13.
[0032] The telescopic driving member 2 is mainly used to provide a driving force for the reciprocating movement of the push rod 21. There are many structural forms, such as an electric screw, a hydraulic cylinder, etc. In this embodiment, the telescopic driving member 2 is a cylinder. The push rod 21 is connected to the cylinder, and the cylinder provides the push rod 21 with a driving force to push the push rod 21 and retreat and reset.
[0033] like Figure 3 As shown, a valve group includes an oil inlet pipe 4 and a plurality of the above-mentioned fluid valves. The oil inlet pipe 4 is connected to a plurality of the valve bodies, and a plurality of the liquid inlet holes 141 are respectively connected to the oil inlet pipe 4.
[0034] In this valve group, when in use, multiple fluid valves can also be combined into a whole for use. Specifically, the valve bodies of multiple fluid valves are interconnected using the oil inlet pipe 4. When in use, fluid is input from the same oil inlet pipe 4 and flows into the multiple fluid valves from multiple liquid inlet holes 141 respectively. It is possible to choose to output fluid from multiple fluid valves at the same time or from a single fluid valve body. The combination is convenient, which greatly improves the flexibility and convenience of fluid transportation.
