Description
[technical field]
The utility model relates to water pump manufacturing field, specifically a kind of New type water pump water inlet-outlet segment.
[background technique]
Currently, water pump application in, water inlet-outlet segment as water pump essential core component its mainly have intake antrum and water outlet
Exocoel forms outer ring cylinder cartridge type around pattern within chamber, and intake antrum is low-pressure area, and water chamber is that higher-pressure region is all cylinder cartridge type
Structure pressure-bearing, brings structure to limit；Intake antrum discharging valve and water chamber discharging valve is generally all arranged in water inlet-outlet segment simultaneously, and production adds
Work and maintenance discharge water all more troublesome.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency, and provides a kind of New type water pump water inlet-outlet segment, structure
Simply, easy to make, water chamber higher-pressure region outer ring, which is designed as ball face-type structural, keeps higher-pressure region pressure-bearing stress more uniform, while only
If a discharging valve at runtime seals intake antrum and water chamber, a discharging valve is only needed out when maintenance discharges water,
Production and processing and maintenance discharge water all more convenient.
A kind of novel water inlet-outlet segment, including water inlet-outlet segment 1, water drain valve core 2, gland 3, elasticity are designed to achieve the above object
4, sealing ring 5, discharge valve seat 6, intake antrum 7 and water chamber 8 are sealed, is provided with intake antrum 7 and water chamber on the water inlet-outlet segment 1
8, the intake antrum 7 be low-pressure area, the water chamber 8 be higher-pressure region, 8 outer ring of water chamber be ball face-type structural, it is described into
Water exit end 1 is equipped with the discharge valve seat 6 that dewatering orifice is provided with threaded connection on disengaging water cavity, the water inlet-outlet segment 1, described to put
It is provided with sealing ring 5 on water valve seat 6 and water inlet-outlet segment is formed and sealed, the discharge valve seat 6 is threadedly coupled water drain valve core 2, described
Water drain valve core 2 and discharge valve seat 6 push down elastic packing 4 by gland 3 and form sealing.
Further, 2 head of water drain valve core is processed as cone structure, the conical surface that the water drain valve core 2 passes through head
It is formed and is sealed with water inlet lumen pore.
The utility model is compared with the existing technology, structure novel, simple, design rationally, ring design outside water chamber higher-pressure region
Keep higher-pressure region pressure-bearing stress more uniform for ball face-type structural, while only setting a discharging valve at runtime by intake antrum and water outlet
Chamber sealing, only needs out a discharging valve when maintenance discharges water, and production and processing and maintenance discharge water all more convenient, is worth pushing away
Wide application.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the longitudinal sectional drawing of this Fig. 1；
In figure: 1, water inlet-outlet segment 2, water drain valve core 3, gland 4, elastic packing 5, elastic packing 6, discharge valve seat 7,
Intake antrum 8, water chamber.
[specific embodiment]
The utility model is made with reference to the accompanying drawing further explained below:
As shown in attached drawing 1, Fig. 2, the utility model includes: water inlet-outlet segment 1, water drain valve core 2, gland 3, elastic packing 4, close
Seal 5, discharge valve seat 6, intake antrum 7 and water chamber 8.It is provided with intake antrum 7 and water chamber 8 on the water inlet-outlet segment 1, wherein into
Water cavity 7 is low-pressure area, and water chamber 8 is higher-pressure region, and 8 outer ring of water chamber, which is designed as ball face-type structural, keeps pressure-bearing more uniform, institute
It states water inlet-outlet segment 1 and is provided with the discharge valve seat 6 that dewatering orifice is provided with threaded connection on disengaging water cavity, the water inlet-outlet segment 1,
It is provided with sealing ring 5 on the discharge valve seat 6 and water inlet-outlet segment is formed and sealed, the discharge valve seat 6 is provided with threaded connection
Water drain valve core 2, the water drain valve core 2 push down elastic packing 4 by gland 3 with discharge valve seat 6 and form sealing, the water drain valve core 2
Head is processed as conical surface pattern, and after water drain valve core 2 is tightened by screw thread, the conical surface and water inlet lumen pore are formed and sealed.
The utility model is simultaneously not limited to the embodiments described above, and other any spirit without departing from the utility model are real
Made changes, modifications, substitutions, combinations, simplifications under matter and principle, should be equivalent substitute mode, be included in practical
Within novel protection scope.
