Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher valves, and particularly relates to a bottom-mounted ring-type fire extinguisher valve. Background Art

[0002] Due to the standard requirements of fire extinguisher valves, a valve core needs to be installed in the pressure gauge hole. As a result, it is necessary to lengthen the length of the pressure gauge hole on the original basis. Such a structural modification will lead to difficulties in die opening of the valve body and an unattractive product appearance. Placing the valve core hole on the right side of the valve body will be the optimal solution. However, whether the valve body is lengthened in the original structure or the valve core hole is placed at the rear, it will limit the insertion of the ring from the upper end of the valve body. In addition, in the existing design, it is often necessary to insert the ring first and then assemble and rivet the handle; this brings inconvenience to subsequent replacement of accessories.

Detailed Embodiments

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the contents disclosed in the present invention.

[0021] Example

[0022] like Figures 1 to 6 As shown, a bottom-mounted bellows type fire extinguisher valve comprises a valve body 2, a valve stem 8 and a handle; the valve stem 8 is arranged in the valve body 2, the upper end of the valve stem 8 is connected to the handle, and the lower end of the valve stem 8 is connected to a spring 14; a valve cap 4 is arranged at the lower end of the valve body 2, and a pressure gauge hole 1 and a valve core hole 5 are arranged on the valve body 2; a bellows 3 is arranged on the periphery of the lower end of the valve body 2, and notches 15 are symmetrically arranged on both sides of the inner hole of the upper part of the bellows 3; the aperture of the inner hole of the upper part of the bellows 3 is smaller than the maximum outer diameter of the lower end of the valve body 2, and the aperture of the notch 15 on the upper part of the bellows 3 is larger than the maximum outer diameter of the lower end of the valve body 2.

[0023] The bead 3 includes a limiting portion 10 at the upper part and a threaded portion 11 at the lower part, and the notch 15 is provided on both sides of the inner hole of the limiting portion 10. Preferably, the notch 15 is an arc-shaped notch. When installing the bead 3, the valve body 2 is tilted with the location of the two notches 15 as the axis, and the bead 3 is inserted into the bead 3 from the top downward, and the valve body 2 is then straightened after the insertion; at this time, since the aperture of the inner hole at the upper part of the bead 3 is smaller than the maximum outer diameter of the lower end of the valve body 2, the straightened valve body 2 will be restricted by the limiting portion 10 at the upper part of the bead 3, so that the maximum outer diameter of the lower end of the valve body 2 is restricted to the inner hole of the limiting portion 10 of the bead 3, and the installation of the bead 3 is completed. In the utility model, since the bead 3 is inserted from the bottom of the valve body 2, the installation of the pressure gauge hole 1, the valve core hole 5 and other components on the valve body 2 will not be affected.

[0024] The valve cap 4 is provided with a plurality of limit blocks 13 in the middle; the spring 14 is a conical spring with a small top and a large bottom; the conical spring is provided between the valve stem 8 and the limit block 13. The valve stem 8 has a boss at the lower end, the upper end of the spring 14 presses against the boss, and the lower end of the spring 14 presses against the limit block 13.

[0025] Among them, a limiting ring 12 is provided in the upper middle part of the outer part of the valve cap 4, and the outer diameter of the limiting ring 12 is greater than the inner diameter of the bottom end of the valve body 2. An external thread is provided on the outer part of the upper section of the valve cap 4, and the external thread is engaged with an internal thread provided on the inner side of the lower end of the valve body 2; the bottom end of the valve body 2 at the top of the limiting ring 12 plays a limiting role.

[0026] Among them, the pressure gauge hole 1 and the valve core hole 5 are arranged at 90 degrees, and the outermost ends of the pressure gauge hole 1 and the valve core hole 5 exceed the maximum outer diameter of the lower end of the valve body 2. Since the outermost ends of the pressure gauge hole 1 and the valve core hole 5 both exceed the maximum outer diameter 16 of the lower end of the valve body 2, if the retaining ring 3 is sleeved into the valve body 2 from above according to the traditional method, it will be stuck by the pressure gauge hole 1 and the valve core hole 5 and the installation cannot be completed; therefore, the installation method of the retaining ring 3 in the present invention is adjusted to be installed from bottom to top. For the traditional retaining ring structure, if it is installed from bottom to top, since the diameter of the upper part of the retaining ring 3 is smaller than the maximum outer diameter of the lower end of the valve body 2, it cannot be sleeved into the valve body 2; therefore, the structural design of the retaining ring is adjusted in the present invention, and notches 15 are symmetrically opened on both sides of the inner hole of the upper part of the retaining ring 3, and the diameter at the notches 15 is greater than the maximum outer diameter of the lower end of the valve body 2. After the valve body 2 is tilted, it can be sleeved into the retaining ring 3 from the notches 15 to complete the installation.

[0027] Among them, a valve rod groove is provided in the upper part of the valve rod 8, and a valve rod sealing ring 9 is provided in the valve rod groove.

[0028] Among them, the handle includes a pressure handle 7, a mounting buckle and a lifting handle 6, and the pressure handle 7 is connected to the lifting handle 6 through the mounting buckle; the pressure handle 7 is connected to the top of the valve body 2 through the rivet.

[0029] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
