Abstract
A kind of local improvement type stop valve, valve gap is arranged on above valve body and by bolt and is connected, valve rod is through valve gap, the bottom of valve rod is pressed on flap, the top of valve rod is provided with Stem Mut and nut successively, Stem Mut and valve rod are in mating connection by screw thread, at Stem Mut top, also fixedly mounted handwheel, and be placed on valve rod with nut, and be pressed on handwheel and above Stem Mut, the top of Stem Mut is arranged in valve gap, and the space below Stem Mut and above pressing plate is provided with guide plate, and this guide plate is arranged in valve gap.Utilize the principle of gate valve opening structure, can be along with valve rod rises together or declines during handwheel rotation, and utilize guide plate positioning and guiding to help the safe and reliable keying of valve, saved the operating space of valve, operated by handwheel gets up also convenient more flexibly, solve such stop valve unpractical problem under some operating mode, improved the working efficiency of valve.
Description
Technical field
The utility model relates to valve class field of mechanical technique, and a kind of local improvement type stop valve particularly, in the horizontal installation pipeline applicable to various operating modes such as oil, chemical industry, pharmacy, power industries.
Background technique
Along with country accelerates to revitalize equipment manufacture policy iterative method, the manufacturing development of general basic will further obtain emphasis support, and " scientific and technical innovation autonomous innovation " become the main flow of current domestic industry development.The use valve rich anies influential family such as China's petrochemical industry, power department, metallurgical department, chemical industry and urban construction grow with each passing day to the demand of valve products, especially the demand of high performance valve product.In infrastructure, for fluid, carry the normal pipeline transport that adopts, valve is controlling component wherein, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, plays indispensable effect.Stop valve is most popular a kind of valve, not only has directivity, can also regulate the flow velocity of pipeline medium, is widely used in enterprise's production.Why very popular it is be due in switching process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, is not only applicable to mesolow, and is applicable to high pressure.The closed principle of stop valve is, relies on valve rod pressure, and valve clack sealing surface and sealing surface of seat are fitted tightly, and stops medium to circulate, and open-shut device is the flap of plug type, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.Its valve rod unlatching or shutoff stroke are relatively short, have cutting function very reliably, the proportional routine relation of the variation of valve seat port and the stroke of flap.Therefore, the shutoff valve of the type is suitable as cut-out or conciliation and throttling use very much.On November 17th, 2011, Yancheng Si Dade financial resources of the people valve Co., Ltd applied for that to Patent Office of State Intellectual Property Office utility model patent " a kind of stop valve " patent No. is 201120457293.8.But the continuous renewal along with technology, stop valve is in the unreasonable part of design also showing slowly, more painstaking during such as throttle down sometimes, during valve rod lifting, handwheel is also along with lifting, occupy space larger, impracticable etc. under some operating mode, need people to be improved, make it more convenient operation, safer, more practical.In order to address the above problem, the technician of R&D institution and enterprise is research and discovery constantly, wishes to overcome the defect that prior art exists, although make some progress technically, still exists the technical problem not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of local improvement type stop valve is provided, its valve gap head design becomes gate valve opening structure form, while making it guarantee Open valve, handwheel is the not lifting along with the lifting of valve rod in situ, and by guide plate locate, guides stem, make it reach reliably the object of opening/shutting valve, thereby saved the working space of handwheel, operated also convenient and practical.
The utility model solves the technological scheme that its technical problem adopts: contain valve body, valve rod, valve gap, handwheel, press female, valve is female, guide plate, valve gap is arranged on above valve body and by bolt and is connected, valve rod is through valve gap, the bottom of valve rod is pressed on flap, the top of valve rod is provided with Stem Mut and nut successively, Stem Mut and valve rod are in mating connection by screw thread, at Stem Mut top, also fixedly mounted handwheel, and be placed on valve rod with nut, and be pressed on handwheel and above Stem Mut, the top of Stem Mut is arranged in valve gap, space below Stem Mut and above pressing plate is provided with guide plate, this guide plate is arranged in valve gap, form a kind of local improvement type stop valve.
The know-why that the utility model adopts is: on existing stop valve structure, improve innovation, but valve gap top design becomes gate valve opening structure form.Because handwheel and Stem Mut are fixed, rotation hand wheel can drive Stem Mut rotation, thereby by screw-thread fit band ovable valve stem, along screw thread, from moving spiral lifting, move, and by guide plate locate, guides stem, make it reach reliably the object of opening/shutting valve.This improvement just easily reaches the object of saving handwheel working space, makes this kind of valve applicable working condition wider.
The beneficial effects of the utility model are: this local improvement type stop valve rational in infrastructure, utilize the principle of gate valve opening structure, can be along with valve rod rises together or declines when handwheel rotates like this, and utilize guide plate positioning and guiding to help the safe and reliable keying of valve, saved the operating space of valve, operated by handwheel gets up also convenient more flexibly, has really solved such stop valve unpractical problem under some operating mode, has improved the working efficiency of valve.
Accompanying drawing explanation
In conjunction with the accompanying drawings and embodiments the utility model to be further described below:
It in figure, is a kind of partial structurtes view of local improvement type stop valve.
In the drawings: 1. valve body, 2. valve rod, 3. valve gap, 4. handwheel, 5. press female, 6. Stem Mut, 7. guide plate.
Embodiment
In the drawings: valve gap 3 is arranged on valve body 1 above and is connected by bolt, valve rod 2 is through valve gap 3, the bottom of valve rod 2 is pressed on flap, the top of valve rod 2 is provided with Stem Mut 6 and nut successively, Stem Mut 6 is in mating connection by screw thread with valve rod 2, at Stem Mut 6 tops, also fixedly mounted handwheel 4, and be placed on valve rod 2 with nut, and be pressed on handwheel 4 and above Stem Mut 6, the top of Stem Mut 6 is arranged in valve gap 3, space below Stem Mut 6 and above pressing plate is provided with guide plate 7, and this guide plate 7 is arranged in valve gap 3.
On existing stop valve structure, improve innovation, but valve gap 3 top design become gate valve opening structure form.Because handwheel 4 and Stem Mut 6 are fixed, thereby rotation hand wheel 4 can drive Stem Muts 6 rotations from moving spiral lifting, to move along screw thread by screw-thread fit band ovable valve stem 2, and by guide plate 7 positioning and guidings, make it reach reliably the object of opening/shutting valve.This improvement just easily reaches the object of saving handwheel 4 working spaces, makes this kind of valve applicable working condition wider, has improved working efficiency.
