Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically to a quick-installation grooved concealed stem fire gate valve. Background Technology

[0002] The grooved concealed stem fire gate valve is a valve specifically designed for fire protection systems. It combines grooved connection technology with concealed stem design. This type of valve is mainly used to control the flow of water and plays a key role in fire protection systems.

[0003] The grooved fire gate valve uses a grooved connection method, which eliminates the need for on-site welding, reducing construction time and the requirement for professional welders. Furthermore, using specialized grooved fittings and fasteners (such as clamps), it allows for quick and easy assembly, offering a faster installation speed compared to standard flange or threaded connections.

[0004] When installing and using this grooved concealed stem fire valve, the following methods should be adopted: Figure 4 The ring-shaped sealing assembly shown is first fitted around the outer edge of one end of the connecting pipe, and then another connecting pipe is fitted into the sealing assembly to ensure that the sealing assembly covers the gap between the two connecting pipes. The sealing assembly is then pressed together by a clamp component, and the clamp component is placed into the groove to stabilize the pipe end direction. This completes the assembly.

[0005] Although the above assembly process is quick, during installation, the position of the sealing component between the two pipes needs to be adjusted (as far as possible to ensure it is centered) to improve the sealing effect and enhance the clamping stability after the subsequent clamp components are connected. Therefore, the adjustment of the sealing component's position is still relatively troublesome. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-installation grooved concealed stem fire gate valve in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model proposes a quick-installation grooved concealed stem fire gate valve, including a valve body, a through pipe fixed on the valve body, a connecting pipe connected to the outside of the through pipe, an annular grooves respectively provided on the periphery of the through pipe and the connecting pipe, a sealing component located between the through pipe and the connecting pipe to connect and seal them, and a clamping component surrounding the sealing component to press it tight. The clamping component extends into the annular grooves of the through pipe and the connecting pipe to fit together.

[0009] The sealing assembly includes a retaining ring, a clamping ring centrally fixed at the inner end of the retaining ring, a tightening ring symmetrically fixed on opposite sides of the clamping ring, two sets of guide strips symmetrically arranged on both sides of the clamping ring, annular grooves respectively provided at the ends of the through pipe and the connecting pipe, and guide grooves fixed around the periphery of the through pipe and the connecting pipe.

[0010] The inner side of the clasp simultaneously fits the outer periphery of the through pipe and the connecting pipe, and the pipe ends of the through pipe and the connecting pipe fit the opposite sides of the clamping ring respectively. The clamping ring is placed in the ring groove and fitted and pressed tightly. The guide strip is fixed inside the clasp and extends into the guide groove through the pipe end or the connecting pipe end respectively. The outer periphery of the clasp is pressed tightly by the clamp assembly.

[0011] As a preferred technical solution of this utility model, each group of guide strips is uniformly arranged in a ring, and multiple guide strips are respectively arranged around the periphery of multiple through pipes and connecting pipes.

[0012] As a preferred embodiment of this utility model, the wrapping ring, clamping ring, tightening ring and guide strip are integrally formed.

[0013] As a preferred embodiment of the present invention, the sealing assembly further includes an annular cavity that is simultaneously located inside the clasp ring, the clamping ring, and the tightening ring.

[0014] As a preferred technical solution of this utility model, the clamp assembly includes two sets of semi-circular ring plates with their inner ring ends facing each other, fixed blocks fixed on the two sets of semi-circular ring plates respectively, bolts passing through the fixed blocks, and nuts threadedly connected to the bolts. The fixed blocks on the two sets of semi-circular ring plates are stabilized by bolts and nuts. The two sides of the semi-circular ring plates are symmetrically provided with protrusions for inserting into the annular grooves. The inner side of the semi-circular ring plates is in contact with the outer side of the ring.

[0015] The beneficial effects of this utility model are as follows:

[0016] By centering a clamping ring inside the clasp, the clamping ring serves as a support surface to stop the insertion of the through pipe and connecting pipe on both sides of the clasp, eliminating the need for additional adjustments to the clasp's position and simplifying operation. Furthermore, the relative compression of the through pipe and connecting pipe against the clamping ring improves the stability of the clasp's position and enhances its sealing performance. Aligning the guide strip with the guide groove provides a positioning effect, improving the accuracy of the connection and increasing installation stability. Inserting a clamping ring into the clasp groove further enhances the stability of the clasp's position and improves its sealing performance. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-4 As shown, this utility model proposes: a quick-installation grooved concealed stem fire gate valve, including a valve body 1 and a through pipe 2 fixed on the valve body 1; the through pipe 2 is provided in two sets and is symmetrically located at the left and right ends of the valve body 1;

[0023] Connecting pipe 3 to the outside of pipe 2; a set of connecting pipe 3 is respectively installed at the pipe ends of pipe 2 on the left and right sides of valve body 1.

[0024] Annular grooves 4 are respectively provided around the periphery of the through pipe 2 and the connecting pipe 3, and a sealing assembly 5 is located between the through pipe 2 and the connecting pipe 3 to connect and seal them.

[0025] and a clamp assembly 6 that surrounds the sealing assembly 5 to press it tightly, the clamp assembly 6 extending into the annular groove 4 of the through pipe 2 and the connecting pipe 3 to fit together;

[0026] The specific structure of the sealing component 5 is shown below:

[0027] The sealing assembly 5 includes a retaining ring 51, a clamping ring 52 centrally fixed at the inner end of the retaining ring 51, a tightening ring 53 symmetrically fixed on opposite sides of the clamping ring 52, two sets of guide strips 54 symmetrically arranged on both sides of the clamping ring 52, annular grooves 55 respectively arranged at the ends of the through pipe 2 and the connecting pipe 3, and guide grooves 56 fixed around the through pipe 2 and the connecting pipe 3.

[0028] The inner side of the clasp 51 is simultaneously attached to the outer sides of the through pipe 2 and the connecting pipe 3, and the pipe ends of the through pipe 2 and the connecting pipe 3 are respectively attached to the opposite sides of the clamping ring 52. The tightening ring 53 is placed in the ring groove 55 and pressed tightly. The guide strip 54 is fixed inside the clasp 51. The guide strip 54 extends into the guide groove 56 through the pipe end of the through pipe 2 or the pipe end of the connecting pipe 3. The outer side of the clasp 51 is pressed tightly by the clamp assembly 6.

[0029] When using the sealing assembly 5, when connecting the through pipe 2 and the connecting pipe 3 at the right end of the valve body 1, the guide strip 54 on the inner side of the clasp 51 is aligned with the guide groove 56 on the through pipe 2 and moved to the left to fit the clasp 51 over the through pipe 2, and stops when the through pipe 2 contacts the clamping ring 52. Similarly, the connecting pipe 3 is inserted after passing through the guide groove 56 and aligning with the guide strip 54 on the inner wall of the clamping ring 52, and then moved to the left, and stops when the connecting pipe 3 contacts the clamping ring 52. The clamping ring 52 is centered on the inner wall of the clasp 51, so there is no need to make additional adjustments to the position of the clasp 51, simplifying the operation.

[0030] Furthermore, the relative compression of the clamping ring 52 by the through pipe 2 and the connecting pipe 3 can improve the stability of the position of the clasp 51 and improve the sealing performance at that position.

[0031] The alignment of the guide strip 54 with the guide groove 56 provides a positioning effect, improves the accuracy of the connection position, and increases the stability of the installation.

[0032] When the aforementioned through pipe 2 and connecting pipe 3 are inserted into the inner position of the clasp 51, the tightening ring 53 is simultaneously inserted into the ring groove 55 for fitting and pressing, so as to further improve the stability of the position of the clasp 51 and improve the sealing performance.

[0033] In this arrangement, multiple guide strips 54 are evenly distributed in a ring around each group, corresponding one-to-one with multiple connecting pipes 2 and connecting pipes 3, and multiple guide strips 54 are respectively provided around their periphery, such as... Figures 1-3 As shown, when the through pipe 2 and the connecting pipe 3 are inserted into the inner side of the clasp 51, the positioning accuracy of the connection can be further improved by using multiple positioning positions.

[0034] Among them, the retaining ring 51, clamping ring 52, tightening ring 53 and guide strip 54 are integrally formed to form such a Figures 2-3 The components shown can be made of nitrile rubber or fluororubber, which is easy to manufacture.

[0035] Furthermore, the sealing assembly 5 also includes an annular cavity 57 located simultaneously within the retaining ring 51, the clamping ring 52, and the tightening ring 53; such as Figure 1 As shown, this is as follows Figures 2-3 The integrally molded component shown has an annular cavity 57 centrally located in its cross-section, which can adapt to changes in pressure, temperature, etc. inside the pipe to maintain a good sealing effect.

[0036] The specific structure of the clamp component 6 is shown below:

[0037] The clamp assembly 6 includes two sets of semi-circular ring plates 61 with their inner ring ends facing each other, fixed blocks 62 fixed on the two sets of semi-circular ring plates 61 respectively, bolts 63 passing through the fixed blocks 62, and nuts 64 threadedly connected to the bolts 63. The fixed blocks 62 on the two sets of semi-circular ring plates 61 are secured by bolts 63 and nuts 64. The two sides of the semi-circular ring plates 61 are symmetrically provided with protrusions for inserting into the annular groove 4. The inner side of the semi-circular ring plates 61 is in contact with the outer side of the wrapping ring 51.

[0038] The convex plates are symmetrically located at the left and right ends of the inner side of the semicircular ring plate 61. The two sets of semicircular ring plates 61 face each other vertically and fit snugly against the inner ring 51. Fixed blocks 62 are symmetrically arranged at the front and rear ends of each set of semicircular ring plates 61. Bolts 63 pass through the fixed blocks 62 on both sets of semicircular ring plates 61 at the same time. When the bolts 63 are attached and supported on the fixed blocks 62, a part of the bolts 63 also protrudes. The nut 64 is then connected to the protruding part of the bolts 63 until it contacts the fixed block 62. In this way, the two semicircular ring plates 61 can be fixed and the ring 51 can be pressed tightly.
