Abstract
The utility model discloses a three-piece-type tank bottom ball valve which comprises a valve body. The valve body comprises a spherical-shaped tank bottom mounting shell body, a sphere mounting shell body and an outlet end shell body. First connecting blocks and second connecting blocks are matched with each other and are distributed along the side walls of the sphere mounting shell body and the outlet end shell body. The first connecting blocks and the second connecting blocks are provided with through holes. Thread holes are formed in the spherical-shaped tank bottom mounting shell body corresponding to the through holes. One ends of screw rods penetrate through the through holes of the first connecting blocks and the second connecting blocks and enter the thread holes, and thread connecting is achieved. The other ends of the screw rods are provided with nuts in a screwing mode. According to the three-piece-type tank bottom ball valve, the valve body clamps and fixes the spherical-shaped tank bottom mounting shell body, the sphere mounting shell body and the outlet end shell body through the combination of the screw rods and the nuts, during machining, parts can be machined respectively, during maintaining, the shell bodies can be separated only by disassembling the screw rods, partial replacing or maintaining can be achieved, maintaining and replacing can be conveniently carried out, and cost can be well saved.
Description
Technical field
The utility model relates to a kind of three pieces type tank bottom ball valve.
Background technique
Tradition three pieces type tank bottom ball valve comprises valve body, but valve body is generally integrated type or two-piece type structure, and complex structure, and therefore processing is difficult for, and change while there is local damage and the cost of maintenance higher.
Model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model has been to provide a kind of convenient three pieces type tank bottom ball valve of processing and keep in repair.
The utility model takes following technological scheme to complete: three pieces type tank bottom ball valve, comprise valve body, valve body comprises holder housing at the bottom of spherical shape tank, sphere installation housing and outlet end housing, on described sphere installation housing and outlet end housing, all along sidewall, be distributed with the first contiguous block and second contiguous block of mutual coupling, on the first contiguous block and the second contiguous block all with through hole, at the bottom of described spherical shape tank, on holder housing, corresponding through hole offers tapped hole, one end of screw rod enters tapped hole through the through hole of the first contiguous block and the second contiguous block and realizes and being threaded, the described screw rod the other end has been tightened nut.
In the utility model, the combination that valve body adopts screw rod and nut by spherical shape tank at the bottom of holder housing, sphere installation housing and outlet end housing clamp and fix, can process respectively each parts man-hour adding, during maintenance, only need dismantling screw can separate each several part housing, can change or keep in repair in part, the carrying out that is conducive to maintenance and changes, is more conducive to cost-saving.
Accompanying drawing explanation
The utility model has following accompanying drawing:
The structure cross-sectional schematic of the three pieces type tank bottom ball valve that Fig. 1 provides for the utility model.
Fig. 2 is the structure enlarged diagram after screw rod on the three pieces type tank bottom ball valve in Fig. 1 and the first contiguous block, the second contiguous block, tapped hole are pegged graft.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings each details and the working principle thereof of embodiment below again.
As Fig. 1, shown in Fig. 2, the three pieces type tank bottom ball valve that the utility model provides, comprise valve body 1, valve body 1 comprises holder housing 2 at the bottom of spherical shape tank, sphere installation housing 3 and outlet end housing 4, on described sphere installation housing 3 and outlet end housing 4, all along sidewall, be distributed with the first contiguous block 5 and second contiguous block 6 of mutual coupling, on the first contiguous block 5 and the second contiguous block 6 all with through hole 7, at the bottom of described spherical shape tank, on holder housing 2, corresponding through hole 7 offers tapped hole 8, one end of screw rod 9 enters tapped hole 8 through the through hole 7 of the first contiguous block 5 and the second contiguous block 6 and realizes and being threaded, described screw rod 9 the other ends have been tightened nut 10.In the present embodiment, at the bottom of described spherical shape tank, holder housing 2 is with annular table terrace 11, and the existence of annular table terrace 11 is convenient to be stuck in dress tank bottom ball valve on the step surface of tank base coupling, is conducive to the installation of three pieces type tank bottom ball valve.
