Abstract
The invention relates to a combined gate valve, which comprises a valve cover, a valve rod and a gland, wherein a valve cap is arranged at the upper end of the valve cover; a stepped hole is formed in the center of the valve cap; the valve rod passes through the stepped hole, and is matched with the stepped hole; and the gland is arranged above the valve cap. A combination of the valve cover and the valve cap is designed instead of an original valve cover with a complex structure, so that a complex structure is dispersed, convenience is brought to manufacturing and installation, and great convenience is brought to future maintenance work; and if a certain part is damaged after the use of the combined gate valve, a corresponding part is used for replacing the damaged part in time without replacing the entire valve cover, so that cost and resources are saved.
Description
Technical field
The present invention relates to the gate valve field, relate in particular to a kind of combination gate valve.
Background technique
Valve is the controlling component in the fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Gate valve is the important control means that promotes the device development of modern transportation water, gas, stream material, also needs easy degree, theftproof performance, anti-plugging etc. the factor with reference to working life, maintenance in control.
The gate valve (as shown in Figure 1) that uses in the market because whole complex contour structure causes endoporus processing inconvenient, is inconvenient to produce, and brings very burden when gate valve is keeped in repair.
And in the situation that certain part is damaged, cause the whole calcellation of gate valve, again change cost of idleness.
Summary of the invention
In view of this, be necessary to provide a kind of convenient production and maintenance, and save the combination gate valve of cost.
The present invention is achieved in that a kind of combination gate valve, comprises valve gap, valve rod and gland, described valve gap upper end is provided with bonnet, and described bonnet center is provided with shoulder hole, and described valve rod passes described shoulder hole, and match with described shoulder hole, described gland is located at described bonnet top.
Further, described gland inside is provided with inner groove.
Further, be provided with seal ring in the described inner groove.
Further, described valve gap is provided with counterbore.
The advantage of combination gate valve provided by the invention is: the present invention is designed to the combination of valve gap and bonnet by the valve gap with original labyrinth, Structure Distribute with complexity, the convenient manufacturing and installation, also give and in the maintenance work in later stage, brought larger convenience, after use, if damaging appears in certain part, in time get final product with changing corresponding component, need with changing whole valve gap, not save cost and resource.

Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1, Fig. 1 is existing valve mechanism schematic representation described in the background technique.
Existing valve comprises valve body 1, valve gap 2, valve plate 3, valve rod 4, valve plate seal ring 5, gland 6, handwheel 7 and valve seals 8.The inside of valve body 1 is provided with larger cavity, and there is unlimited opening at two ends, is convenient to like this entering and flowing out of fluid.Valve gap 2 is installed in the top of valve body 1, and valve gap 2 inside are provided with certain cavity, and the cavity of this cavity and valve body 1 inside mates mutually.Be provided with valve seals 8 between valve gap 2 and the valve body 1, in case fluid leakage utilizes the locking nut (not shown) that the three tightly is locked together.The oral area of valve gap 2 upper ends is less, and the oral area inboard is provided with internal thread.
Larger cavity central position at valve body 1 is equipped with valve plate 3, between the both sides of valve plate 3 and the valve body 1 valve plate seal ring 5 is installed, and valve plate 3 is flat tabular, and its size is slightly larger than the cavity in the valve body 1, just in time can stop fluid to flow in valve body 1.Valve rod 4 is installed directly over the valve plate 3, is provided with outside thread on the valve rod 4.Valve rod 4 passes the oral area of valve gap 2 upper ends, and the internal thread of the outside thread on the valve rod 4 and valve gap 2 oral areas is intermeshing.
Be provided with gland 6 in valve gap 2 upper ends, gland 6 neutral positions are provided with center hole, gland 6 and valve gap 2 screw-threaded couplings.Gland 6 upper ends are provided with handwheel 7, and handwheel 7 centers are provided with elongated center-pole 7a, and center-pole 7a passes the center hole of gland 6, are connected and fixed with valve rod 4.
When rotation hand wheel 7,4 rotations of center-pole 7a band ovable valve stem, under valve gap 2 oral area screw-thread fit, valve rod 4 rotations also move up and down, and drive moving up and down of valve plate 3 by moving up and down of valve rod 4 like this, finally realize the open and close of valve.
See also Fig. 2, Fig. 2 is the structural representation that the present invention makes up gate valve.
Combination gate valve of the present invention is to improve on existing valve mechanism basis, and it improves component and comprises: valve gap 2 ' and gland 6 '.
Described combination gate valve comprises valve gap 2 ', valve rod 4 ' and gland 6 ', described valve gap 2 ' upper end is provided with bonnet 9, and described bonnet 9 centers are provided with shoulder hole 10, and described valve rod 4 ' passes described shoulder hole 10, and match with described shoulder hole 10, described gland 6 ' is located at described bonnet 9 tops.
