Description

Technical Field

[0001] The utility model relates to the field of faucets, in particular to a stainless steel welding faucet. Background Art

[0002] Many faucets today contain an inner core for water flow. When installing the inner core, the inner core is inserted from the lower end of the shell and pushed upward until it contacts the step at the upper end of the shell to form a limit position. Since the sealing ring is usually installed at the upper part of the inner core where water flows out, when installing the inner core, the sealing ring on the inner core will have a long friction stroke with the side wall of the shell, which may cause the sealing ring to wear, deform, or fail.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0004] The main purpose of the utility model is to provide a stainless steel welding faucet, which has the function of reducing the risk of sealing ring failure.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A stainless steel welded faucet, comprising a stainless steel shell, an inner core, a pressure cover and a base, wherein the shell forms a cavity with upper and lower ends communicating with each other, the base is welded to the lower end of the shell, the inner core is installed in the cavity, the lower end of the inner core abuts against the base, a valve core is installed on the upper part of the inner core, the pressure cover is fixedly connected to the upper end of the shell, the pressure cover abuts against the upper end of the valve core and fixes the inner core in the cavity; a positioning block is formed at the upper end of the base, a positioning groove is formed at the lower end of the inner core, and the positioning block is inserted into the positioning groove.

[0007] Furthermore, the shell is formed by processing from a stainless steel pipe.

[0008] Furthermore, a water outlet hole is formed on the side wall of the shell, and a water outlet is formed on one side of the inner core, and the water outlet is connected to the water outlet hole; a water outlet pipe is welded on the outer wall of the shell at the water outlet hole position, and a sealing ring is installed between the inner core and the inner wall of the shell at the position of the water outlet hole.

[0009] Furthermore, a thread is formed on the upper end of the shell, and the gland and the shell are connected via the thread.

[0010] Furthermore, a valve core seat is formed on the upper part of the inner core, a valve core is installed in the valve core seat, the sealing ring is installed on the side wall of the valve core seat, and the position where the thickness of the side wall of the valve core seat is the largest is located at A on the side away from the sealing ring.

[0011] Further, a guiding inclined surface is formed at the lower end of the valve core seat.

[0012] After adopting the above structure, a stainless steel welded faucet involved in the present utility model has at least the following beneficial effects:

[0013] First, during installation, the inner core is inserted into the cavity from the upper end of the housing, so that the friction stroke between the sealing ring and the inner wall of the housing is shorter, which can reduce the deformation and wear of the sealing ring and avoid the problem of water leakage caused by the failure of the sealing ring.

[0014] Second, the housing is directly cut and formed from a stainless steel round pipe, which greatly reduces the processing and manufacturing cost.

[0015] Third, the position with the largest side wall thickness of the valve core seat is located on the side away from the sealing ring. The thicker wall thickness can provide higher strength, so less deformation can make the sealing ring seal more tightly between the inner core and the housing.

[0016] Compared with the prior art, the present utility model reduces the friction stroke of the sealing ring through a stainless steel welded faucet, avoiding the problems of wear, deformation and failure of the sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0027] As Figures 1 to 3As shown, it is a stainless steel welding faucet involved in the utility model, including a stainless steel shell 1, an inner core 2, a gland 3 and a base 4. The shell 1 is formed with a cavity 11 with upper and lower ends communicating with each other. The base 4 is welded to the lower end of the shell 1. The inner core 2 is installed in the cavity 11. The lower end of the inner core 2 abuts against the base 4. A valve core 100 is installed on the upper part of the inner core 2. The gland 3 is fixedly connected to the upper end of the shell 1. The gland 3 abuts against the upper end of the valve core 100 and fixes the inner core 2 in the cavity 11. A positioning block 41 is formed at the upper end of the base 4, and a positioning groove 21 is formed at the lower end of the inner core 2. The positioning block 41 is inserted into the positioning groove 21. During installation, the inner core 2 is loaded into the cavity 11 from the upper end of the shell 1, so that the friction stroke between the sealing ring 14 and the inner wall of the shell 1 is shorter, which can reduce the deformation and wear of the sealing ring 14 and avoid the problem of water leakage caused by failure of the sealing ring 14.

[0028] Preferably, the housing 1 is formed by processing a stainless steel tube. The housing 1 is directly cut and formed by a stainless steel round tube, which greatly reduces the processing and manufacturing cost.

[0029] Preferably, a water outlet hole 12 is formed on the side wall of the shell 1, and a water outlet 22 is formed on one side of the inner core 2, and the water outlet 22 is connected to the water outlet hole 12; a water outlet pipe 13 is welded to the outer wall of the shell 1 at the position of the water outlet hole 12, and a sealing ring 14 is installed between the inner core 2 and the inner wall of the shell 1 at the position of the water outlet hole 12. During installation, the water outlet 22 and the water outlet hole 12 can be aligned and maintained in a connected state through the cooperation of the positioning groove 21 and the positioning block 41.

[0030] Preferably, a thread is formed on the upper end of the shell 1, and the gland 3 and the shell 1 are connected via the thread.

[0031] Preferably, if Figure 1 and Figure 2 As shown, a valve core seat 23 is formed on the upper part of the inner core 2, a valve core 100 is installed in the valve core seat 23, and the sealing ring 14 is installed on the side wall of the valve core seat 23, and the position of the maximum thickness of the side wall of the valve core seat 23 is located on the side away from the sealing ring 14. The position of the maximum thickness of the side wall of the valve core seat 23 is located at A on the side away from the sealing ring 14, and a thicker wall thickness can provide higher strength, so less deformation can make the sealing ring 14 more tightly sealed between the inner core 2 and the housing 1.

[0032] Preferably, a guide slope 24 is formed at the lower end of the valve core seat 23. In this way, when the inner core 2 is installed, the inner core 2 can be installed into the housing 1 more smoothly.

[0033] Compared with the prior art, the utility model reduces the friction stroke of the sealing ring 14 through a stainless steel welded faucet, avoiding the problems of wear and deformation failure of the sealing ring 14.

[0034] The above embodiments and drawings do not limit the product form and style of the utility model. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the utility model.
