Abstract
The invention discloses a general stop valve. The general stop valve comprises a valve body, a valve rod movably inserted into the valve body, a bonnet sleeved on the valve rod, and a guide device arranged between the valve rod and the bonnet. The guide device is composed of a guide part connected between the valve rod and the bonnet in a clamping mode, and a sliding part fixed on the valve rod and connected with the guide part in a sliding mode. The guide part is provided with a sliding portion opposite to the sliding part, and the sliding portion is parallel with the valve rod. The general stop valve is simple in structure. Under different valve operation modes, the bonnet is general, cost is saved, modularized flexible production of products is achieved, and the production cycle is shortened.
Description
Technical field
The present invention relates to a kind of stop valve, particularly a kind of universal cutoff valves.
Background technique
We know, stop valve is a kind of block valve of extensive use, are mainly used in switching on or off the MEDIA FLOW in pipeline and use as certain flow control valve
.its application mainly contains in the pipeline of water, steam, pressurized air and various petrochemical industry materials.Be typically designed to the rotation and lifting valve rod for the common operated by handwheel stop valve that switches on or off the pipeline fluid, and operate when stop valve need adopt gear-box, or electronic automatic operation, and stop valve need design while using as flow control valve, the stop valve valve rod must be designed to not rotation and lifting bar.Traditional design, for to cast out guiding rib on stop valve valve gap support, is installed a guide pad and joins work by taper pin and valve rod on valve rod.For guaranteeing accurate positioning, need first first assembling during assembling, determine the position of guide pad on valve rod, then valve rod and guide pad are removed to join after boring fixed pin holes do final assembling.Traditional design part heaviness, difference requires the valve gap design different, and casting mould is many, and manufacturing cost is high, and the cycle is long; Prior art can't address these problems.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of Modular Flexible production that has realized product, general a kind of universal cutoff valves at different valve operation mode bottom flanges.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of universal cutoff valves comprises: valve body, and activity is inserted in the valve rod in valve body, is placed in the valve gap on valve rod, is placed in the guiding device between valve rod and valve gap; Guiding device forms to be had: be connected in the guiding element between valve rod and valve gap, be fixed on valve rod and be slidably connected to the slider of guiding element; Guiding element is provided with the slide part with respect to slider, and slide part is parallel to valve rod.
Aforesaid a kind of universal cutoff valves, valve rod is formed with: the receiving groove of standing part slider, slider is flat key.
Aforesaid a kind of universal cutoff valves, valve rod also is formed with: be placed in the assembly department of valve stem tip, assembly department is thread tracks, and thread tracks is the trapezoidal thread track.
Aforesaid a kind of universal cutoff valves, guiding element is flange, slide part is the sliding-groove be placed on the inwall of flange.
Aforesaid a kind of universal cutoff valves, the endoporus of flange is provided with the flange internal thread with respect to thread tracks.
Aforesaid a kind of universal cutoff valves, the joint of flange and valve gap is formed with screw pair.
Usefulness of the present invention is: of the present invention simple in structure, and general at different valve operation mode bottom flanges, save cost, and realized the Modular Flexible production of product, shortened the manufacture cycle.
The accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the present invention sectional view;
Fig. 2 is the sectional view of a kind of embodiment's guiding device of the present invention;
The implication of reference character in figure:
1 valve body, 2 valve rods, 201 receiving grooves, 202 thread tracks, 3 valve gaps, 4 flanges, 401 sliding-grooves, 5 flat keys, 6 screw pairs.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of universal cutoff valves comprises: valve body 1, activity is inserted in the valve rod 2 in valve body 1, is placed in the valve gap 3 on valve rod 2, is placed in the guiding device between valve rod 2 and valve gap 3.
Guiding device forms to be had: be connected in the guiding element between valve rod 2 and valve gap 3, be fixed on valve rod 2 and be slidably connected to the slider of guiding element; Guiding element is provided with the slide part with respect to slider, and slide part is parallel to valve rod 2.
Valve rod 2 is formed with: the receiving groove 201 of standing part slider, and the slider of another part is slidably connected in sliding-groove 401; As a kind of preferred embodiment, slider is flat key 5, particularly a kind of A type flat key 5.Valve rod 2 also is formed with: be placed in the assembly department on valve rod 2 tops, as a kind of preferred, assembly department is thread tracks 202, is particularly preferably trapezoidal thread track 202, it should be noted that, uses the benefit of trapezoidal thread track 202 to be to be convenient to install smoothly fast.
Guiding element is flange 4, and slide part is the sliding-groove 401 be placed on the inwall of flange 4.The endoporus of flange 4 is provided with flange 4 internal threads with respect to thread tracks 202.Flange 4 is formed with screw pair 6 with the joint of valve gap 3, illustrates between flange 4 and valve gap 3 it is also to be flexibly connected by screw thread.The present invention is band neck thread flange by the flange 4 adopted, and the special construction of this flange 4, well played the purpose that guiding element and link unite two into one.
It should be noted that: first flange 4 is threaded connection on valve gap 3, valve rod 2 penetrates from 3 stomidiums of valve gap, before valve rod 2 receiving grooves 201 enter flange 4 endoporus, at the interior installation flat key 5 of the receiving groove 201 of valve rod 2, guarantee that flat key 5 completes the top assembling before being fit into flange 4 sliding-grooves 401.
Slide on the sliding-groove 401 that the present invention forms at flange 4 inwalls by the flat key 5 be arranged on valve body 1, limited the sphere of activities of valve rod 2, can not rotate by 360 degree, can only move up and down in the scope of sliding-groove 401.The present invention is without any requirement to valve gap 3, only need to use common valve gap 3, no matter the stop valve of which kind of driving mode is as handwheel, gear-box, electronic, the pneumatic grade used same valve gap 3, makes valve parts accomplish seriation, standardization, generalization, inventory reduction, improved the flexibility of product specification, the different requirement of reply client, shortened the manufacturing cycle greatly.
Above demonstration and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
