Abstract
The utility model relates to a rubber seal ball valve used for disconnecting and connecting medium in a water feeding and discharging pipeline. The valve body has split type structure, a transmission device is arranged at the top end of the valve and is connected with the valve shaft, a full bore spherical valve is connected on the valve shaft in the valve body, and a rubber sealing ring is fixed on the spherical valve through an adjusting plate, a pressing plate and a stainless steel bolt, to which rust protection processing is performed. The utility model has the advantages of a ball valve, a gate valve, a butterfly valve and a stop valve, the flow direction of the medium is not limited, the flow state is not changed, the water power loss is small, no water power vibration exists, and the circular area of the water carrying section is equal to the pressure pipe surface. The utility model is rapidly opened and closed, the sealing ring is adjustable, the valve is not required to be disassembled during the maintenance, and therefore the utility model is especially suitable for a water feeding and discharging pipe system with large flow rate and high current speed.
Description
Technical field:
The utility model relates to the ball valve that blocks, is communicated with medium in the water supply and sewerage pipeline system.
Background technique:
Be widely used in that industries such as electric power, metallurgy, municipal engineering are given, block, be communicated with the valve that medium is used in the sewerage system, butterfly valve, stop valve, gate valve, ball valve etc. are arranged.Its butterfly valve and stop valve flow resistance coefficient are big, and cavitation phenomenon is arranged, and easily produce turbulent flow, and line pressure is increased.And the sealing surface of gate valve is vulnerable to erosion and scratch, and its profile is big, and structure is comparatively complicated, maintenance difficult.Simultaneously, it is long that stop valve, gate valve open and close the time.Ball valve then is generally Cast Steel, cost height, is unsuitable for doing bigbore valve, and its seal ring is installed on the valve body, in case wearing and tearing just need the dismounting valve upgrade seal ring again.
Summary of the invention:
The purpose of this utility model is to provide a kind of rubber seal ball valve, is used for substituting the butterfly valve that blocks, is communicated with medium on the pressure line, stop valve and gate valve, ball valve.
The technical solution of the utility model realizes as follows:
The utility model comprises valve body, valve, valve shaft, metal o-ring, transmission device, and transmission device is connected in valve tip and links to each other with valve shaft, and valve links to each other in valve body and with valve shaft, and metal o-ring is on valve body; Its valve body is split type linkage structure, and valve body and end valve body during promptly valve body is divided into, valve are all-pass footpath spherical, and rubber seal is installed on the valve.With fixedly being connected on the valve through antirust processing regulator plate, pressing plate and stainless steel screw.
Advantage of the present utility model is as follows:
1, the utlity model has the characteristic of ball valve, possess gate valve simultaneously, the advantage of butterfly valve, stop valve.It is simple in structure, and open-close convenient is rapid, and is applied widely, and MEDIA FLOW does not produce and boosts to unrestricted.
2, valve body of the present utility model makes it have enough strength and stiffness owing to adopted split-type structural.The inside nominal diameter maximum can reach 3000mm, nominal pressure 0～2.5Mpa, and install, easy to maintenance.
3, valve of the present utility model (being valve plate) is all-pass footpath spherical, and its flow cross-section circular area equates that with the pressure piping section hydraulic loss is very little, current by the time do not change fluidised form, no hydraulic vibration.
4, seal ring of the present utility model can be regulated by adjusting screw, and the compensate for wear amount is regulated seal pressure, and it is big to be specially adapted to flow, and flow velocity is high gives, drainage system.
Description of drawings:
Fig. 1 is the utility model structural drawing;
Fig. 2 is the utility model structure I enlarged view;
Embodiment:
Referring to accompanying drawing embodiment, the utility model is further described:
Among Fig. 1-2: valve body 4 tops during transmission device 1 is connected in by connecting base 3, valve body is split type welded structure, valve body 4 is linked as valve body with end valve body 6 promptly, composite bearing 5, valve 7 is connected on the valve shaft 2, valve shaft 2 is connected on the transmission device 1, valve 7 is in valve body, valve 7 is an all-pass footpath spherical, seal ring 8 is a rubber seal, it is installed on the valve 7, is fixed on the valve 7 with regulator plate 9, pressing plate 11 and stainless steel adjusting screw 10 through antirust processing, with the seal pressure of adjusting screw 10 adjustable sealing circles 8.
