Abstract
The utility model provides a novel multifunctional marine valve which is convenient and practical and consists of a valve cover (1), a valve body (2), a valve rod (3), a hand wheel (4), a middle bushing (5), a connecting tenon (6), a valve disk (7), a sealing surface (8), a shifting fork (9), a spring (10) and a gland nut (11). The novel multifunctional marine valve is characterized in that the valve body (2) is connected with the middle bushing (5); the shifting fork (9) is arranged inside the middle bushing (5); and the connecting tenon (6) of the valve rod (3) penetrates through a tenon hole of the middle bushing (5). The novel multifunctional marine valve has the functions of opening, closing, checking and throttling, realizes multiple purposes, is simple and reasonable in structure, not only simplifies a pipeline structure greatly, but also reduces the loss of medium fluid, and saves marine space, thereby realizing excellent economic efficiency.
Description
Technical field
The utility model relates to a kind of marine valve, relates in particular to a kind of Multifunction marine valve.
Background technique
Along with developing rapidly of shipping and shipping industry, the demand of marine valve constantly increases, and its technical requirements is also improving day by day.In order to reduce the installation cost of marine valve, practice thrift hull space and weight, compact valve mechanism, simplification boat-carrying pipeline, realization multi-purpose valve are the inevitable designing requirements of marine valve.
Existing ship is with the valve products of valve products and various marine valve prescribed by standard, can be divided into having by its function and block or the stop valve of turn-on power loss, stop safety check that medium flows backwards and the throttle valve of regulating rate-of flow and pressure etc. to realize the marine valve of simple function; Corresponding with it; In the boat-carrying pipeline, also just have by pipeline, non-return pipeline and throttling pipeline; This valve and pipeline thereof not only make the boat-carrying pipe-line system become very complicated, increase the fluid resistance loss of fed sheet of a media, and have increased taking up room and the gross weight of hull of boat-carrying accessories such as valve, pipeline significantly; Also strengthened simultaneously the control difficulty of marine valve, incompatible with the demand for development of modern ships.
Summary of the invention
In order to solve above technical problem; The utility model provides a kind of convenient and practical Multifunction marine valve; Constitute by valve gap (1), valve body (2), valve rod (3), handwheel (4), interstage bushing (5), joint tongue (6), valve disc (7), sealing surface (8), shift fork (9), spring (10), gland nut (11); It is characterized in that being connected with on the said valve body (2) interstage bushing (5), shift fork (9) is located at interstage bushing (5) inside, and the joint tongue (6) of valve rod (3) passes the mortise of interstage bushing (5); In the inner of valve rod (3) valve disc (7) is installed, the position of this valve disc (7) is corresponding with sealing surface (8) position on the valve body (2); Valve gap (1) is connected with valve body (2) through gland nut (11), and this valve gap (1) seals with valve rod (3) through stuffing box packing mutually, and handwheel (4) is fixedly mounted on the sponson of valve rod (3), is provided with spring (10) between valve disc (7) and the valve rod (3).
The beneficial effect of the utility model is: this practicality newly mould have unlatching, close, the function of non-return, throttling, realized multi-purpose valve, simple and reasonable; Both simplified pipeline structure greatly; Reduce the medium fluid loss, also saved space peculiar to vessel, have fabulous Economy.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, be lined with gasket seal between this valve body (2) and the valve gap (1), gland nut (11) is loaded on valve gap (1) on the valve body (2) through being threaded hermetically.Valve rod (3) passes the inner chamber that valve gap (1) arrives valve body (2), is filled with filler hermetically between valve gap (1) and the valve rod (3), and the overhanging end of valve rod (3) is installed with handwheel (4), is used to pull valve rod (3).Valve body (2) is gone up and to be connected with interstage bushing (5) through connecting thread, is equipped with screw thread on the outer cylinder of interstage bushing (5), and the position of center line of interstage bushing (5) is provided with the square hole of falling, and the joint tongue (6) of valve rod (3) passes this square mortise and extends to the inner chamber of valve body (2); The inner of interstage bushing (5) is provided with shift fork (9), shift fork (9) just at the right time fork insert in valve disc (7) on, between valve disc (7) and valve rod (3), be provided with spring (10).Pull handwheel (4), make valve rod (3) upwards turn interstage bushing (5), the shift fork (9) of interstage bushing (5) upwards promotes or presses down valve disc (7) through valve disc (7) convex shoulder.When valve disc (7) is promoted to upper limit position, valve is in opening state.Valve rod (3) turns interstage bushing (5) downwards, and shift fork (9) presses down and pushed up the back side of valve disc (7), and valve disc (7) is pressed on the sealing surface (8) of valve body (2), and this moment, valve was in closed condition.
