Abstract
The utility model discloses a water pump inlet outlet valve mounting structure, include: water pump, rubber shock attenuation larynx, sealed go-between and butterfly valve, the rubber shock attenuation larynx include the rubber tube and set up in first ring flange and second ring flange on the rubber tube, the one end of rubber shock attenuation larynx with the water inlet or the delivery port of water pump pass through first ring flange is connected, the other end pass through the second ring flange with the butterfly valve is connected, wherein, sealed go-between seal set up in between rubber shock attenuation larynx and the butterfly valve, the seal end face at sealed go-between both ends respectively with the rubber tube reaches the butt joint terminal surface of rubber of butterfly valve docks. This water pump inlet outlet valve mounting structure, rational in infrastructure, simple to operate adopts sealed go-between to replace traditional flange nipple joint to realize the sealing connection of rubber shock attenuation larynx and butterfly valve, when guaranteeing the leakproofness, the space that occupies is littleer, more adapts to little space installation.
Description
Technical Field
The utility model relates to a water pump connection structure field provides a water pump inlet outlet valve mounting structure very much.
Background
In a multi-circulation pump parallel system or a circulation pump hot standby system, in order to facilitate replacement of water pumps, a butterfly valve is usually arranged at an inlet and an outlet of each water pump. The sealing part of butterfly valve is the rubber material, with the rubber shock attenuation larynx for the water pump with belong to the soft seal type, usually, need set up one section flange nipple joint in the centre when two soft seal parts establish ties to guarantee sealed effect. However, the flange short section is large in size and is not suitable for a scene with a small water pump installation space.
Therefore, a novel water pump inlet outlet valve mounting structure is provided, so that the water pump inlet outlet valve mounting structure can adapt to small space installation, and meanwhile, the sealing performance of the connection between the rubber damping throat and the butterfly valve is not influenced, so that the problem to be solved urgently is solved.
SUMMERY OF THE UTILITY MODEL
In view of this, an object of the utility model is to provide a water pump inlet outlet valve mounting structure to adopt among the water pump inlet outlet valve mounting structure flange nipple joint connection rubber shock attenuation larynx and the problem that the occupation space that the butterfly valve exists is big, be not suitable for little space installation.
The utility model provides a technical scheme is: water pump inlet outlet valve mounting structure includes: water pump, rubber shock attenuation larynx, sealed go-between and butterfly valve, the rubber shock attenuation larynx include the rubber tube with set up in first ring flange and second ring flange on the rubber tube, the one end of rubber shock attenuation larynx with the water inlet or the delivery port of water pump pass through first ring flange is connected, the other end pass through the second ring flange with the butterfly valve is connected, wherein, sealed go-between seal set up in between rubber shock attenuation larynx and the butterfly valve, the seal face at sealed go-between both ends respectively with the rubber tube reaches the butt joint terminal surface butt joint of rubber of butterfly valve.
Preferably, the sealing end faces at the two ends of the sealing connecting ring are provided with sealing waterlines.
The utility model provides a water pump inlet outlet valve mounting structure, rational in infrastructure, simple to operate adopts sealed go-between to replace the sealing connection that traditional flange nipple joint realized rubber shock attenuation larynx and butterfly valve, when guaranteeing the leakproofness, the space that occupies is littleer, more adapts to little space installation.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
fig. 1 is a schematic structural view of a water pump inlet/outlet valve mounting structure provided by the present invention;
FIG. 2 is a schematic end view of the seal attachment ring;
FIG. 3 is a side schematic view of the seal attachment ring;
fig. 4 is a schematic structural diagram of a conventional flange short section.
Detailed Description
The invention will be further explained below with reference to specific embodiments, without limiting the invention.
As shown in fig. 1 to 3, the utility model provides a water pump inlet outlet valve mounting structure, include: water pump 1, rubber shock attenuation larynx 2, sealed go-between 3 and butterfly valve 4, rubber shock attenuation larynx 2 include the rubber tube 21 with set up in first ring flange 22 and second ring flange 23 on the rubber tube 21, the one end of rubber shock attenuation larynx 2 with the water inlet or the delivery port of water pump 1 pass through first ring flange 22 is connected, the other end pass through second ring flange 23 with butterfly valve 4 is connected, wherein, sealed go-between 3 sealed set up in between rubber shock attenuation larynx 2 and the butterfly valve 4, the seal end face at sealed go-between 3 both ends respectively with the rubber tube 21 reaches the butt joint of rubber butt joint terminal surface of butterfly valve 4.
This water pump inlet outlet valve mounting structure adopts sealed go-between to replace traditional flange nipple joint to realize the sealing connection of rubber shock attenuation larynx and butterfly valve, by figure 3, figure 4 can know, the thickness of sealed go-between is far less than the thickness of traditional flange nipple joint, can reduce water pump inlet outlet valve mounting structure's installation space greatly, and adaptability is higher, and in addition, the cost of the sealed go-between that simple structure, thickness are littleer compares traditional flange nipple joint lower.
As the improvement of the technical scheme, the sealing end faces at the two ends of the sealing connecting ring 3 are respectively provided with a sealing waterline, wherein the width of the sealing end face of the sealing connecting ring and the arrangement mode of the sealing waterline are kept consistent with those of a sealing face of a common flange, so that the sealing connecting ring and the common flange are ensured to have the same sealing effect.
The embodiments of the present invention are written in a progressive manner, emphasizing the differences of the various embodiments, and similar parts can be referred to each other.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
