Abstract
The utility model discloses an industrial or civil dual-purpose valve. A non-return structure is added to an ordinary disconnecting valve or an adjusting valve or a balance valve to form a disconnecting and non-return valve or an adjusting and non-return valve or a balance and non-return valve; therefore, the purpose of providing a dual-purpose valve is realized; not only materials are saved, but also manpower and material resources for installation, construction, etc. are reduced.
Description
The utility model relates to the design and the manufacturing field of industry and civilian valve.
Existing valve is a valve one usefulness usually, and in industrial and civilian pipeline, safety check normally is used with stop valve, modulating valve etc., waste material and manpower and materials.
The purpose of this utility model provides the valve of two kinds of effects of an a kind of valve, make a valve play the effect that the effect of stop valve and safety check or effect that valve plays modulating valve and safety check or valve play equilibrium valve and safety check, the dual-purpose manpower and materials of having saved material and installation etc. of such valve.
The purpose of this utility model is achieved in that in the valve rod 1 of stop valve or modulating valve or equilibrium valve and is processed with deep hole, valve rod 1 and flap 2 are made split type, there is a guide rod 3 at flap 2 rear portions, guide rod 3 can insert in the deep hole in the valve rod 1, spring 4 is housed on the guide rod 3, effect by spring 4 and fluid when making fluid reflux is combined closely flap 2 and seal ring 5, reaches the purpose of non-return, and is like this can a valve dual-purpose.
The utlity model has following good effect: a valve is dual-purpose, economical with materials and reduced the man power and material of installation etc.
Below in conjunction with drawings and Examples the utility model is described in further detail, Fig. 1,2 is a structural representation of the present utility model:
1. the guide rod on valve rod 2. flaps 3. flaps
4. spring 5. seal rings
Embodiment 1
Fig. 1 is the Two purpose valve that stop valve and safety check are integrated, valve rod 1 and flap 2 are split type, be processed with deep hole in the valve rod 2, flap 2 rear portions have guide rod 3, guide rod 3 can insert in the deep hole in the valve rod 1, and can freely do axial activity, spring 4 is housed, the spring suitable on the guide rod according to the pressure design of different calibers and fluid.Work as valve opening, because the pressure of fluid, flap 2 is in the position I, and fluid can pass through valve by forward (the diagram direction of arrow).When fluid reflux,, play the effect of safety check because the pressure of spring 4 and fluid makes flap be in position II and closely combination of seal ring 5.
Fig. 2 is the Two purpose valve that equilibrium valve and safety check are integrated, valve body and adjusting part are with common equilibrium valve, inner sealing partly adopts structure of the present utility model, so both can assign to control flap 2 opening degrees and regulate flow, can reach the purpose of safety check again by the pressure of this spring 4 and fluid by adjusting portion.
Claims (1)
- A kind of Two purpose valve is to add what non-return structure formed on common stop valve or modulating valve or equilibrium valve, it is characterized in that:Valve rod and flap are split type, be processed with deep hole in the valve rod, there is a guide rod at the flap rear portion, guide rod can insert in the interior deep hole of valve rod, spring is housed on the guide rod, effect by spring and fluid when making fluid reflux is combined closely flap and seal ring, reaches the purpose of non-return, and is like this can a valve dual-purpose.
