TECHNICAL FIELD

[0001] The present application relates to the field of three-way ball valves, in particular to a jacket for a three-way fixed ball valve. BACKGROUND

[0002] The conventional full-jacketed ball valve adopts full-jacketed wrapping to expose only the pressure sleeve and the valve stem to actuate the valve to open and close, thereby achieving good heat preservation and cold preservation effects.

[0003] The medium flows in the valve for a long time, which causes great damage to the inner parts of the valve, and the valve needs to be regularly maintained without affecting safety. Since the valve body is fully jacketed, the condition of the valve cannot be observed, and the heat preservation jacket needs to be disassembled or the entire valve needs to be replaced during maintenance, which is inconvenient for regular maintenance and observation, and thus needs to be improved. CONTENT OF THE INVENTION

[0004] In order to improve the problem that the full-jacketed valve is inconvenient for maintenance and observation of the valve body, the present application provides a jacket for a three-way fixed ball valve.

[0005] The jacket for a three-way fixed ball valve provided by the present application adopts the following technical solution:

[0006] The jacket for a three-way fixed ball valve comprises a valve body and a jacket, the valve body is provided with an inflow passage and two outflow passages, the valve body is provided with a valve cavity, the inflow passage and the outflow passages are in communication with the valve cavity, the valve cavity is provided with a communication assembly, the communication assembly is used to control the communication between the inflow passage and the outflow passages, the valve body is provided with a packing box, the communication assembly penetrates through the packing box, and the jacket is sleeved on the valve body, and the packing box penetrates through the jacket.

[0007] By adopting the above technical solution, when in use, the jacket is bent and formed by a plate material and is attached to the outer sidewall of the valve body, and then the jacket is welded on the valve body to fix the jacket on the valve body. At this time, the jacket wraps the valve body, so that the medium flowing in the valve body reaches an ideal heat preservation or cold preservation state.

[0008] The packing box wraps part of the valve body and penetrates through the jacket, so that the jacket cannot wrap the part of the valve body in contact with the packing box, thereby causing a gap in the jacket at the packing box, i.e., the part of the valve body in contact with the packing box is exposed outside, which is convenient for maintenance and observation of the three-way fixed ball valve. The packing box also wraps the valve body and can play a role in heat preservation and cold preservation of the valve body, i.e., the part of the valve body not wrapped by the jacket is wrapped by the packing box, and the heat preservation and cold preservation effects of the two parts are close, which is convenient for maintenance and observation without affecting the heat preservation and cold preservation effect of the valve body.

[0009] Optionally, a plurality of support rods are fixed on the inner wall of the jacket.

[0010] By adopting the technical scheme, the support rod is supported between the jacket and the valve body, thereby supporting the jacket, preventing the jacket from being deformed under pressure, and improving the stability of the structure of the jacket.

[0011] Optionally, an end of the support rod away from the jacket is fixed with a rubber pad, and the rubber pad abuts against the outer sidewall of the valve body.

[0012] By adopting the technical scheme, the rubber pad plays a protective role, and the support rod is in soft contact with the sidewall of the valve body, thereby preventing the support rod from damaging the valve body.

[0013] Optionally, the outer sidewall of the jacket is provided with a mounting sleeve, and rock wool is arranged between the mounting sleeve and the jacket.

[0014] By adopting the technical scheme, the mounting sleeve covers the entire jacket, and the rock wool prevents heat transfer, thereby playing a heat preservation and cold insulation effect on the jacket, and further increasing the heat preservation and cold insulation effect of the jacket on the valve body.

[0015] Optionally, a mounting rod is fixed on the jacket, a mounting hole is formed in the mounting sleeve, the mounting rod can be arranged through the mounting hole, a containing hole is formed in the sidewall of the mounting rod, a fixing block is arranged in the containing hole, the fixing block is connected with the inner wall of the containing hole through a fixing spring, and the fixing block can limit the mounting sleeve between the fixing block and the jacket.

[0016] By adopting the technical scheme, when mounting, the mounting hole is aligned with the mounting rod, the fixing block is pressed, the fixing spring is compressed, the fixing block is accommodated in the containing hole until the sidewall of the mounting rod is not protruding, then the mounting rod is relatively arranged through the mounting hole until the mounting sleeve passes the fixing block, at this time, the force pressing the fixing block is removed, the fixing spring restores the deformation, the fixing block is pushed out of the containing hole, the fixing block is in contact with the sidewall of the mounting sleeve, and the fixing block limits the mounting sleeve between the fixing block and the valve body, thereby achieving the mounting of the mounting sleeve on the valve body.

[0017] Optionally, a guide surface is arranged on the sidewall of the fixing block, and the mounting sleeve abuts against the guide surface, so as to drive the fixing block to be accommodated in the containing hole.

[0018] By adopting the technical scheme, when the mounting hole is aligned with the mounting rod and the mounting rod is relatively arranged in the mounting hole, the mounting sleeve will first contact the guide surface, the guide surface plays a guiding role, the mounting sleeve moves along the guide surface on the guide surface, thereby the fixing block is gradually accommodated in the containing hole and the fixing spring is pressed, until the mounting sleeve can pass the fixing block to reach between the fixing block and the valve body, at this time, the mounting sleeve is separated from the guide surface, the fixing block is popped out of the containing hole under the action of the fixing spring, thereby limiting the mounting sleeve on the valve body, and in this process, the installation of the mounting sleeve can be completed without manually pressing the fixing block.

[0019] Optionally, a limiting block is arranged on the side wall of the fixing block, and a limiting groove is arranged on the inner wall of the accommodating hole, and the limiting block is inserted into the limiting groove and can move in the limiting groove.

[0020] By adopting the above technical scheme, when the fixing spring pops out the fixing sleeve from the accommodating hole, the limiting block moves in the limiting groove until the limiting block moves to the end of the limiting groove, at this time, the limiting block cooperates with the limiting groove to limit the continuous movement of the limiting block, that is, the fixing block cannot continue to move out of the accommodating hole, so that the fixing block cannot completely move out of the accommodating hole, and the stability of the connection between the fixing block and the mounting rod is increased.

[0021] Optionally, an iron block is arranged on the mounting sleeve, and a magnetic block is arranged on the side wall of the clamping sleeve, and the iron block can be attracted to the magnetic block.

[0022] By adopting the above technical scheme, when the mounting sleeve is attached to the clamping sleeve, the attraction between the magnetic block and the iron block enables the mounting sleeve to be quickly positioned on the clamping sleeve, which facilitates the insertion of the mounting rod into the mounting hole and improves the installation efficiency.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The packing box wraps the valve body and is provided with a clamping sleeve, so that the clamping sleeve cannot wrap the part of the valve body in contact with the packing box, thereby causing a gap in the packing box, that is, the part of the valve body in contact with the packing box is exposed, which facilitates the maintenance and observation of the three-way fixed ball valve. The packing box also wraps the valve body, which can also play a role in keeping the valve body warm or cold, that is, the part of the valve body not wrapped by the clamping sleeve is wrapped by the packing box, and the warm or cold keeping effects of the two parts are similar, which facilitates maintenance and observation without affecting the warm or cold keeping effect of the valve body.

[0025] 2. The mounting sleeve covers the entire clamping sleeve, and the rock wool prevents heat transfer, thereby playing a role in keeping the clamping sleeve warm or cold, thereby increasing the warm or cold keeping effect of the clamping sleeve on the valve body. BRIEF DESCRIPTION OF DRAWINGS

The jacket 40 is formed by bending and welding a plate material, three jackets 40 are pre-prepared, and then the three jackets are integrally welded to form a jacket 40, and then the jacket 40 is cut along the horizontal center line of the flange 40 to facilitate the jacket 40 to be sleeved on the valve body 10. When the valve body 10 and the jacket 40 are assembled, the original welding seam of the jacket 40 is welded, and then the edge of the jacket 40 in contact with the valve body 10 is welded to realize the fixed installation of the jacket 40 on the valve body 10.

[0035] In use, the jacket 40 is formed by bending a plate material and is attached to the outer wall of the valve body 10, and then the jacket 40 is welded on the valve body 10 to fix the jacket 40 on the valve body 10.

[0040] Referring to Figure 2 and Figure 3 The guide surface 62 is cut on the side wall of the fixing block 60, the guide surface 62 is inclined away from the one end of the fixing spring 61 and towards the valve body 10, when the mounting hole 51 is aligned with the mounting rod 42, and the mounting rod 42 is relatively arranged in the mounting hole 51, the mounting sleeve 50 will first contact the guide surface 62, the guide surface 62 plays a guiding role, so that the mounting sleeve 50 relatively moves on the guide surface 62 along the guide surface 62, thereby the fixing block 60 is gradually received in the containing hole 421 and presses the fixing spring 61, until the mounting sleeve 50 can pass the fixing block 60 to reach between the fixing block 60 and the valve body 10, at this time, the mounting sleeve 50 is separated from the guide surface 62, the fixing block 60 is popped out of the containing hole 421 under the action of the fixing spring 61, thereby limiting the mounting sleeve 50 on the valve body 10. In this process, the installation of the mounting sleeve 50 can be completed without manually pressing the fixing block 60.

[0041] And the side wall of the fixed block 60 is integrally formed with a limiting block 63, a limiting groove 422 is arranged on the inner wall of the accommodating hole 421, the limiting groove 422 is arranged along the moving direction of the fixed block 60, the limiting block 63 is inserted into the limiting groove 422 and can move in the limiting groove 422, when the fixed spring 61 pops out the fixed sleeve from the accommodating hole 421, the limiting block 63 moves in the limiting groove 422 until the limiting block 63 moves to the end of the limiting groove 422, at this time, the limiting block 63 cooperates with the limiting groove 422 to limit the continuous movement of the limiting block 63, that is, the fixed block 60 cannot continue to move out of the accommodating hole 421, so that the fixed block 60 cannot completely move out of the accommodating hole 421, and the stability of the connection between the fixed block 60 and the mounting rod 42 is increased.

[0042] Referring to Figure 2 And Figure 3 In order to facilitate the quick alignment of the mounting sleeve 50 with the mounting rod 42 and the insertion, the iron block 52 is arranged on the mounting sleeve 50, the magnetic block 43 is arranged on the side wall of the clamping sleeve 40, and the iron block 52 can be attracted to the magnetic block 43. When the mounting sleeve 50 is attached to the clamping sleeve 40, the attraction between the magnetic block 43 and the iron block 52 enables the mounting sleeve 50 to be quickly positioned on the clamping sleeve 40, facilitating the insertion of the mounting rod 42 into the mounting hole 51 and improving the installation efficiency.

[0043] The implementation principle of the clamping sleeve 40 for the tee fixed ball valve in the embodiment of the application is as follows: in use, the clamping sleeve 40 is bent and formed from a plate material and is attached to the outer side wall of the valve body 10, and then the clamping sleeve 40 is welded to the valve body 10, so that the clamping sleeve 40 is fixed on the valve body 10. At this time, the clamping sleeve 40 wraps the valve body 10, so that the medium flowing in the valve body 10 reaches an ideal heat preservation or cooling state.

[0044] The packing box 30 wraps part of the valve body 10 and penetrates the clamping sleeve 40, so that the clamping sleeve 40 cannot wrap the part of the valve body 10 in contact with the packing box 30, thereby causing the clamping sleeve 40 to have a gap at the packing box 30, that is, the part of the valve body 10 in contact with the packing box 30 is exposed, facilitating the maintenance and observation of the tee fixed ball valve. The packing box 30 also wraps the valve body 10 and can also play a role in heat preservation and cooling of the valve body 10, that is, the part of the valve body 10 not wrapped by the clamping sleeve 40 is wrapped by the packing box 30, and the heat preservation and cooling effects of the two parts are close, facilitating the maintenance and observation while not affecting the heat preservation and cooling effect of the valve body 10.
