Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a front-mounted two-way water valve core. Background Technology

[0002] The valve core is the core component of a valve, and its function is to control the flow of fluid in a pipeline. The valve core is usually installed inside the valve body. By adjusting the position of the valve core, the cross-sectional area of ​​the fluid passage through the valve is changed, thereby regulating the flow rate. Its performance and quality directly affect the overall working performance and service life of the valve.

[0003] To maintain a constant water temperature and improve the user experience, showerheads are generally equipped with thermostatic valve cores. A thermostatic valve core is a valve core that uses a heat-sensitive material to determine the temperature and adjust the water inlet and outlet. Typically, a component made of materials such as paraffin wax or shape memory alloy is placed at the water outlet as a thermostatic component. When hot and cold water mix at different temperatures, the thermostatic component will deform according to the temperature to control the water inlet and outlet. When the temperature reaches the set temperature, water is released to achieve constant temperature water output.

[0004] Traditional showers typically have a pre-set switch. However, the valve core on the pre-set switch only has the functions of diverting and closing the water flow, and does not have the function of blocking hot water from entering the faucet. This causes the thermostatic valve core inside the faucet to be impacted by hot water, resulting in long-term thermal expansion of the thermostatic component and reducing its service life. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a front-mounted two-way valve core that can isolate hot water from entering the faucet, thereby cutting off the hot water supply and preventing hot water from entering the thermostatic valve core. This avoids the thermostatic valve core from long-term thermal expansion, improves its service life, and has a smaller overall size, which can reduce the size of the faucet and meet subsequent usage needs.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A pre-operated two-way water valve core includes a housing. From top to bottom, the housing is provided with a drive shaft, a drive seat, a moving plate, a stationary plate, an upper disc-type water sealing ring, a base, and a lower disc-type water sealing ring. The bottom of the drive shaft is connected to the drive seat via a fixing pin. The upper end of the moving plate is engaged with the bottom of the drive seat. The stationary plate abuts against the bottom of the moving plate and the upper disc-type water sealing ring. The base is engaged with the stationary plate and the housing. A hot water inlet is provided on the side of the housing.

[0008] Preferably, the transmission seat is provided with a ratchet ball and a spring, the ratchet ball abutting against the outer shell and the transmission seat respectively, and the spring abutting against the ratchet ball and the spring respectively.

[0009] Preferably, a first sealing ring is fitted on the upper side of the outer casing, and a plurality of second sealing rings are fitted on the bottom outer side of the drive shaft.

[0010] Preferably, the moving plate has a hot water inlet channel on its side, a mixing outlet cavity at the center of the moving plate, and a water-sealing end face at the bottom of the moving plate. The hot water inlet channel is connected to the hot water inlet end.

[0011] Preferably, the stationary plate is provided with a hot water inlet, a first mixing outlet, a second mixing outlet and a mixing inlet, the hot water inlet is connected to the hot water inlet channel, and the mixing outlet cavity is connected to the first mixing outlet, the second mixing outlet and the mixing inlet respectively.

[0012] Preferably, the sealing end face is connected to the upper plate-type sealing ring and the lower plate-type sealing ring respectively.

[0013] By adopting the above technical solution, the pre-loaded two-way valve core provided by this utility model has the following beneficial effects: The outer shell of the pre-loaded two-way valve core is provided with, from top to bottom, a drive shaft, a drive seat, a moving plate, a stationary plate, an upper disc-type sealing ring, a base, and a lower disc-type sealing ring. The bottom of the drive shaft is connected to the drive seat via a fixing pin. The upper end of the moving plate is engaged with the bottom of the drive seat. The stationary plate abuts against the bottom of the moving plate and the upper disc-type sealing ring. The base is engaged with the stationary plate and the outer shell. A hot water inlet is provided on the side of the outer shell. In use, by turning the drive shaft, the drive shaft drives the drive seat to rotate, which in turn drives the moving plate to rotate, thereby sealing or opening the water channels on the outer shell and the stationary plate. This prevents hot water from entering the faucet, thus cutting off the hot water supply and preventing hot water from entering the thermostatic valve core, making it safer. It also avoids long-term thermal expansion of the valve core, improving its service life. Furthermore, the overall size is small, which is conducive to the optimization of the internal structure and facilitates the implementation of the flow channel, reducing the size of the faucet, meeting subsequent usage needs, and improving the yield rate.

[0026] like Figure 1-8As shown, the pre-activated dual-displacement valve core includes a housing 1. From top to bottom, the housing 1 is sequentially arranged with a drive shaft 2, a drive seat 3, a moving plate 4, a stationary plate 5, an upper disc-type water-sealing ring 6, a base 7, and a lower disc-type water-sealing ring 8. The bottom of the drive shaft 2 is connected to the drive seat 3 via a fixing pin 9. The upper end of the moving plate 4 is engaged with the bottom of the drive seat 3. The stationary plate 5 abuts against the bottom of the moving plate 4 and the upper disc-type water-sealing ring 6. The base 7 is engaged with the stationary plate 5 and the housing 1. A hot water inlet 10 is provided on the side of the housing 1. It can be understood that this pre-activated dual-displacement valve core is used for distributing and closing the shower faucet, and can isolate the hot water supply to the inside of the faucet.

[0027] Specifically, the transmission seat 3 is provided with a ratchet ball 11 and a spring 12. The ratchet ball 11 abuts against the outer shell 1 and the transmission seat 3 respectively, and the spring 12 abuts against the ratchet ball 11 and the spring 12 respectively. A first sealing ring 13 is sleeved on the upper side of the outer shell 1, and several second sealing rings 14 are sleeved on the bottom outer side of the transmission shaft 2.

[0028] Specifically, the moving plate 4 has a hot water inlet channel 15 on its side, a mixing outlet cavity 16 at its center, and a sealing end face 17 at its bottom. The hot water inlet channel 15 is connected to the hot water inlet 10. The stationary plate 5 has a hot water inlet 18, a first mixing outlet 19, a second mixing outlet 20, and a mixing inlet 21. The hot water inlet 18 is connected to the hot water inlet channel 15, and the mixing outlet cavity 16 is connected to the first mixing outlet 19, the second mixing outlet 20, and the mixing inlet 21, respectively. The sealing end face 17 is connected to the upper plate-type sealing ring 6 and the lower plate-type sealing ring 8, respectively. It is understandable that... Figure 7 As shown, at this time, the moving plate 4 opens 120 degrees clockwise, the hot water inlet channel 15 is connected to the hot water inlet 15, the mixing outlet chamber 16 is connected to the first mixing outlet 19, and the second mixing outlet 20 is in the closed state; as Figure 8 As shown, at this time, the moving plate 4 opens 120 degrees counterclockwise, the hot water inlet channel 15 is connected to the hot water inlet 15, the first mixing outlet 19 is closed, and the mixing outlet chamber 16 is connected to the second mixing outlet 20.

[0029] Understandably, this utility model has a reasonable design and unique structure. When in use, by turning the transmission shaft 2, the transmission shaft 2 drives the transmission seat 3 to rotate, and the transmission seat 3 drives the moving plate 4 to rotate, thereby sealing or opening the water channels on the outer shell 1 and the stationary plate 5. This can prevent hot water from entering the faucet, thus cutting off the hot water supply and preventing hot water from entering the thermostatic valve core, making it safer. It also avoids the valve core from being heated and expanding for a long time, improving its service life. Furthermore, the overall size is small, which is conducive to the optimization of the internal structure and facilitates the implementation of the flow channel. This can reduce the size of the faucet, meet subsequent usage needs, and improve the yield rate.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
