Description

Technical Field

[0001] The present application relates to the technical field of stop valves, and in particular to a Y-type stop valve. Background Art

[0002] In the related technologies in the field of valve manufacturing, when testing products, such as quality inspection and dimension measurement of valves, the workpiece needs to be placed upright; and the common Y-type stop valve needs other supports or tools for auxiliary support to keep the valve upright because the center of gravity is offset from the main body of the valve body. In addition, the valve also needs a relatively stable support when transporting or placing it to reduce the contact wear between the valve surface and the ground or other objects.

[0003] The above technical solution has the following defects: it is not always possible to find objects in time to support the valve and enable the valve to be placed stably; and how to support the valve quickly and conveniently is also a problem that needs to be solved. Summary of the invention

[0004] In view of the shortcomings of the related technology, the present application provides a Y-type stop valve with a self-supporting structure that can quickly and conveniently maintain an upright position.

[0005] The Y-type stop valve provided in this application adopts the following technical solution:

[0006] A Y-type stop valve comprises a valve body, wherein the water inlet and water outlet ends of the valve body are respectively provided with a water inlet flange and a water outlet flange; a valve seat obliquely extending toward the water outlet flange is provided in the middle of the valve body; a valve cover is provided at the upper end of the valve seat, and a valve stem penetrating into the valve body is provided on the valve cover; a bracket assembly for supporting the balance of the valve body is provided on the valve seat; the bracket assembly comprises a left supporting frame and a right supporting frame rotatably connected to both sides of the valve seat; accommodating grooves for the left supporting frame and the right supporting frame to be embedded are respectively provided on both sides of the valve seat; the left supporting frame and the right supporting frame can be rotated outwards until the ends are located in the plane where the end wall of the water inlet flange is located.

[0007] By adopting the above technical solution, when the valve body is erected, one end of the water outlet flange is vertically downward as the contact end, and the overall center of gravity of the stop valve is close to the side where the valve seat and the valve stem are located, causing the valve body to tilt toward that side; at this time, the lower ends of the left support frame and the right support frame are supported on the ground, which can support one side of the valve seat, so that the valve body can remain in an upright position for easy transportation and inspection; and when the stop valve does not need to be supported to stand up, the left support frame and the right support frame can be rotated to hide in the accommodating groove to avoid damage to the bracket assembly or affect the use of the stop valve.

[0008] Preferably, a fixing plate and a mounting plate are respectively provided on the ends opposite to the valve seat and the valve cover; a fixing column extending toward the mounting plate is provided on the fixing plate, a through hole for the fixing column to pass through is provided on the mounting plate, and a fixing nut is threadedly connected to the end of the fixing column passing through the through hole; an annular gasket is provided around the valve stem on the end surface of the mounting plate facing the fixing plate, so that a receiving groove is formed between the fixing plate and the mounting plate.

[0009] By adopting the above technical solution, the fixing plate and the mounting plate are fixedly connected by two flanges, and a receiving groove for accommodating the left support frame and the right support frame is formed between the two, which facilitates the manufacture and processing of the valve body.

[0010] Preferably, the outer walls on both sides of the left support frame and the right support frame when they are rotated into the accommodating groove are set as outer walls, and the inward side walls are set as inner walls; there are four fixed columns in total, and the four fixed columns are evenly arranged in the accommodating groove along the circumference of the valve stem; the left support frame and the right support frame are respectively rotatably connected to the two fixed columns close to the water inlet flange; the inner walls of the left support frame and the right support frame are provided with makeshift grooves that cooperate with the fixed columns close to the water outlet flange.

[0011] By adopting the above technical solution, the fixed column not only connects the mounting plate and the fixed plate, but also serves as the rotating axis of the left support frame and the right support frame; and the setting of the give way groove reasonably utilizes the space size of the accommodating groove, so that the left support clamp and the right support frame can enter the accommodating groove.

[0012] Preferably, the right support frame is provided with a through hole penetrating toward the left support frame, and a connecting screw is slidably connected in the through hole; a threaded hole for threaded connection of the connecting screw is provided at a position corresponding to the through hole on the left support frame; and both ends of the connecting screw can be located in the through hole and the threaded hole respectively.

[0013] By adopting the above technical solution, when the left support frame and the right support frame are rotated to the supporting position, one end of the connecting screw is screwed into the threaded hole, so that the two ends of the connecting screw are respectively located in the through hole and the threaded hole, thereby connecting and fixing the left support frame and the right support frame, preventing the left support frame and the right support frame from rotating, and enhancing the stability of the support.

[0014] Preferably, the outer walls on both sides of the left support frame and the right support frame when they are rotated into the accommodating groove are set as outer walls, and the other opposite side wall is set as inner wall; the through hole is a countersunk hole, including a small-diameter sliding hole arranged on the outer wall and a large-diameter sliding hole arranged on the inner wall; the connecting screw includes a rod portion slidably arranged in the small-diameter sliding hole and a head portion slidably arranged in the large-diameter sliding hole.

[0015] By adopting the above technical solution, the head and the countersunk hole are used to limit the connection screw, thereby preventing the connection bolt from completely falling out of the through hole.

[0016] Preferably, the threaded hole includes a large-diameter threaded hole arranged on the outer side wall of the left support frame and a small-diameter threaded hole arranged on the inner side wall of the left support frame; the small-diameter threaded hole and the large-diameter threaded hole can respectively cooperate with the rod and head threads.

[0017] By adopting the above technical solution, when the left support frame and the right support frame are rotated into the accommodating groove, the connecting screw is rotated through the small-diameter sliding hole so that the head thread is connected to the large-diameter threaded hole, thereby fixing the left support frame and the right support frame in the accommodating groove.

[0018] Preferably, the left support frame and the right support frame are respectively rotatably connected to a stabilizing frame; the left support frame and the right support frame are provided with angle limiting blocks for limiting the rotation angle of the stabilizing frame; when the left support frame and the right support frame are rotated until the ends are located in the plane where the end wall of the water inlet flange is located, and the stabilizing frame is rotated to abut against the lower end surface of the angle limiting block, at this time, the lower end surface of the stabilizing frame and the end wall of the water inlet flange are located in the same plane.

[0019] By adopting the above technical solution, the contact area between the bracket assembly and the storage platform is increased by using the stabilizing frame, thereby increasing the stability of the valve body placement.

[0020] Preferably, the two stabilizing frames are rotatably connected to the outer side walls of the left support frame and the right support frame respectively along the axis of the through hole and the small-diameter threaded hole; a clearance hole for rotation and for the connection screw to pass through is provided at the rotation axis of the stabilizing frame.

[0021] By adopting the above technical solution, when the left support frame and the right support frame are retracted into the accommodating groove, the stabilizing frame can also be retracted and brought together to both sides.

[0022] Preferably, a limiting rod is provided on the side wall of the stabilizing frame facing the connected left supporting frame or right supporting frame; and a limiting groove for the limiting rod to be embedded is provided on the end wall of one side of the left supporting frame and the right supporting frame opposite to the limiting angle block.

[0023] By adopting the above technical solution, the limiting rod and the limiting groove are used to limit the rotation angle of the stabilizing frame when it is folded, and when the left support frame and the right support frame are retracted into the accommodating groove, the limiting rod extending into the accommodating groove is also restricted, so that the stabilizing frame cannot rotate.

[0024] In summary, the beneficial effects of this application are:

[0025] 1. When the valve body is erected, one end of the outlet flange is vertically downward as the contact end, and the overall center of gravity of the stop valve is close to the side where the valve seat and the valve stem are located, causing the valve body to tilt toward that side; at this time, the lower ends of the left and right support frames are supported on the ground to support one side of the valve seat, so that the valve body can be kept in an upright position for easy transportation and inspection; and when the stop valve does not need to be supported and erected, the left and right support frames can be rotated to hide in the accommodating groove to avoid damage to the bracket assembly or affect the use of the stop valve;

[0026] 2. When the left support frame and the right support frame are rotated to the support position, screw one end of the connecting screw into the threaded hole so that the two ends of the connecting screw are respectively located in the through hole and the threaded hole, thereby connecting and fixing the left support frame and the right support frame to prevent the left support frame and the right support frame from rotating and enhancing the stability of the support.

[0033] This embodiment discloses a Y-type stop valve. Figure 1As shown, it comprises a valve body 1, the water inlet and water outlet ends of the valve body 1 are welded with a water inlet flange 11 and a water outlet flange 12 respectively; and a valve seat 2 is integrally formed in the middle of the valve body 1 and extends obliquely toward the water outlet flange 12, so that the stop valve is Y-shaped as a whole. A valve cover 3 is arranged on the upper end of the valve seat 2, and a valve stem 31 that penetrates into the valve body 1 is rotatably connected to the valve cover 3, and a hand wheel 32 is fixedly connected to the valve stem 31, so that the valve stem 31 can be rotated to open and close the valve.

[0034] like Figure 1 , Figure 2 As shown, a fixing plate 21 and a mounting plate 33 are welded to the opposite ends of the valve seat 2 and the valve cover 3, respectively. Four fixing columns 211 extending toward the mounting plate 33 are welded to the fixing plate 21. The four fixing columns 211 are evenly arranged along the circumference of the valve stem 31 and are arranged side by side in pairs. A through hole 331 is provided on the mounting plate 33 for the fixing columns 211 to pass through. The ends of the fixing columns 211 passing through the through hole 331 are threadedly connected with fixing nuts 212. The fixing nuts 212 are tightened to achieve a fixed connection between the valve cover 3 and the valve seat 2. An annular gasket 332 is integrally formed around the valve stem 31 on the end surface of the mounting plate 33 facing the fixing plate 21, so that a receiving groove 22 is formed between the fixing plate 21 and the mounting plate 33, and the four fixing columns 211 are arranged around the receiving groove 22.

[0035] like Figure 2 , Figure 3 As shown, the valve seat 2 is provided with a support assembly 4 for supporting the balance of the valve body 1, and the support assembly 4 includes a left support frame 41 and a right support frame 42 which are rotatably connected to the two sides of the receiving groove 22, and the outer walls of the left support frame 41 and the right support frame 42 when they are rotated into the receiving groove 22 are set as the outer wall a, and the side wall facing inward is set as the inner wall b. The left support frame 41 and the right support frame 42 are respectively rotatably connected to two fixing columns 211 close to the water inlet flange 11, and the inner wall b of the left support frame 41 and the right support frame 42 is provided with a clearance groove b1 which cooperates with the fixing column 211 close to the water outlet flange 12; and when the left support frame 41 and the right support frame 42 are rotated outward to abut each other, the lower ends of the two are just located in the plane where the end wall of the water inlet flange 11 is located. When the valve body 1 is erected, one end of the water outlet flange 12 is vertically downward as a contact end, and the lower ends of the left support frame 41 and the right support frame 42 are supported on the ground, which can support one side of the valve seat 2, so that the valve body 1 can be kept in an upright position for easy transportation and inspection; and when the stop valve does not need to be supported to stand up, the left support frame 41 and the right support frame 42 can be rotated to hide in the accommodating groove 22 to avoid damage to the bracket assembly 4 or affect the use of the stop valve.

[0036] like Figure 3 , Figure 4As shown, the right support frame 42 is provided with a through hole 421 penetrating toward the left support frame 41, and a connecting screw 43 is slidably connected in the through hole 421. The through hole 421 is a countersunk hole, including a small-diameter sliding hole 4211 set on the outer side wall a and a large-diameter sliding hole 4212 set on the inner side wall b; the connecting screw 43 includes a rod 432 slidably set in the small-diameter sliding hole 4211 and a head 431 slidably set in the large-diameter sliding hole 4212, and a cross-shaped groove (not marked in the figure) for rotating the connecting screw 43 is provided on the end surface of the rod 432 and the head 431.

[0038] As shown in FIG3 , the two stabilizing frames 44 are rotatably connected to the outer side wall a of the left support frame 41 and the right support frame 42 along the axis of the through hole 421 and the small-diameter threaded hole 411, and a clearance hole (not shown in the figure) for rotation and for the connection screw 43 to pass through is provided at the rotation axis of the stabilizing frame 44. When the left support frame 41 and the right support frame 42 are retracted into the accommodating groove 22, the stabilizing frame 44 can also be retracted and closed to both sides.

[0039] like Figure 3As shown, a limiting rod 441 is welded on the side wall of the stabilizing frame 44 facing the connected left supporting frame 41 or right supporting frame 42, and a limiting groove d for the limiting rod 441 to be inserted is provided on the side end wall of the left supporting frame 41 and the right supporting frame 42 opposite to the angle limiting block c. The limiting rod 441 and the limiting groove d are used to limit the rotation angle of the stabilizing frame 44 when it is retracted, and when the left supporting frame 41 and the right supporting frame 42 are retracted into the receiving groove 22, the limiting rod 441 extending into the receiving groove 22 is also restricted, so that the stabilizing frame 44 cannot rotate.
