The valve body is axially provided with an inlet end and an outlet end which are connected with a pipe fitting, internal threads or external threads which are connected with the pipe fitting are arranged at the inlet end and the outlet end, a valve seat is arranged at the intersection position of the inlet end and the outlet end of the valve body, a valve port which penetrates through a medium is arranged on the valve seat, the valve cover is arranged above the valve body, the pressing cap is arranged above the valve cover, the valve clack is arranged at the valve port in the valve body in an opening mode, one end of the valve rod penetrates through the pressing cap and the valve cover to be fixedly connected with the valve clack, the hand wheel is arranged at a free end of the valve rod, the outer diameter of the inlet end of the valve body is different from that of the outlet end of the valve body, and the inner diameter of the inlet end of the valve body is different from that of the outlet end of the valve body. The reducing stop valve is reasonable in structural design and can be directly connected among pipe fittings with different diameters.
Description
Technical field
The utility model relates to a kind of fluid control valve, particularly a kind of reducing stop valve.
Background technique
Stop valve also is pipe valve, is installed on the circulation that is used for the pilot line medium in the pipeline or ends; Generally comprise valve body, valve rod, valve gap, flap, pressure cap and handwheel, said valve body is provided with entrance point and the outlet end that is connected with pipe fitting vertically, and said entrance point is provided with internal thread or the outside thread that is connected with pipe fitting with outlet end; The adjacent place of friendship that said valve body is positioned at entrance point and waterexit end also is provided with valve port, and said valve gap is located at the valve body top, and pressure cap is located at the valve gap top; But being located in the valve body on the said valve port of said flap folding; One end of said valve rod passes pressure cap and valve gap and flap and is connected, and said handwheel is located on the free end of valve rod, during use; Thereby the flap and the valve port that can drive the upper and lower slippage drive of valve rod valve rod lower end through the turn handwheel are done the opening and closing action, realize circulation or the function of ending.The equal diameters of above-mentioned stop valve entrance point and outlet end only is applicable to the pipe fitting that connects feed-water end and the same diameter of waterexit end, during actual use; Normal appearance need be between the pipe fitting of different-diameter the attaching valve, the pipe connection fittings that need increase other during connection are realized being connected between above-mentioned pipe fitting and the valve, fitting operation is complicated; Time-consuming, effort have increased the junction point of pipeline, have improved installation and maintenance cost; Take pipeline location, make troubles to the workmen.
Summary of the invention
To the problems referred to above, the utility model proposes a kind of reasonable in design, can directly insert the reducing stop valve between the different-diameter pipe fitting.
For solving this technical problem, the utility model is taked following scheme: a kind of reducing stop valve comprises valve body, valve rod, valve gap, flap, pressure cap and handwheel; Said valve body is provided with entrance point and the outlet end that is connected with pipe fitting vertically; Said entrance point is provided with internal thread or the outside thread that is connected with pipe fitting with outlet end, and the adjacent place of friendship that said valve body is positioned at entrance point and waterexit end is provided with valve seat, and said valve seat is provided with the valve port that connects medium; Said valve gap is located at the valve body top; Pressure cap is located at the valve gap top, but on the valve port of being located at said valve seat in the valve body of said flap folding, an end of said valve rod passes pressure cap and valve gap and flap and is connected; Said handwheel is located on the free end of valve rod, and the external diameter and the internal diameter of said valve body entrance point and outlet end are all inequality.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model reducing stop valve, and the external diameter and the internal diameter of said valve body entrance point and outlet end are all inequality, have solved the problem that directly inserts pipe valve between the different-diameter pipe fitting; Convenient installation and operation; Save the consumption and the construction operation amount of pipe fittings, reduced the junction point of pipeline, the bonding point of having reduced dielectric leakage.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 1, present embodiment discloses a kind of reducing stop valve, comprises valve body 1, valve gap 2, valve rod 3, flap 4, pressure cap 5 and handwheel 6; Said valve body 1 is provided with the entrance point 11 and outlet end 12 that is connected with pipe fitting vertically; Said entrance point 11 is provided with internal thread or the outside thread that is connected with pipe fitting with outlet end 12, and said valve body 1 is positioned at entrance point 11 and is provided with valve seat 13 with the adjacent place of the friendship of outlet end 12, and said valve seat 13 is provided with the valve port 131 that connects medium; Said valve gap 2 is located at valve body 1 top; Said pressure cap 5 is located at valve gap 2 tops, but on the valve port of being located at said valve seat 13 in the valve body 1 131 of said flap 4 foldings, an end of said valve rod 3 passes valve gap 2 and is connected with flap 4; Said handwheel 6 is located on the free end of valve rod 3, and said valve body 1 entrance point 11 is all inequality with the external diameter and the internal diameter of outlet end 12.
The utility model reducing stop valve; The external diameter and the internal diameter of said valve body entrance point and outlet end are all inequality; Solved the problem that directly inserts pipe valve between the different-diameter pipe fitting, convenient installation and operation, the consumption and the construction operation amount of having saved pipe fittings; Reduce the junction point of pipeline, reduced the bonding point of dielectric leakage.
The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
