Abstract
The invention relates to a lubricating-type plug valve. The lubricating-type plug valve comprises a valve body and a valve base, and the valve body is connected with the valve base through a bolt. An inlet and an outlet are formed in the valve base. An oil injecting plug screw is arranged in the valve body and connected with a valve rod, and the valve rod is connected with a check valve and a plug cock. The bottom of the valve base is planar, an oil storing groove is formed in the side wall of the valve base, and epoxy resin layers are sprayed on the surface of the valve body and the surface of the valve base. The lubricating-type plug valve is simple in structure and convenient to operate and use, and still has the better sealing effect after long-time use; and parts do not need to be frequently replaced, the maintenance cost is low, the production cost is reduced, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of lubricating type stopcock.
Background technique
Stopcock is the rotary valve of closure member or plunger shape, makes the passway on valve plug identical with the passway on valve body or separate by 90-degree rotation, realizes the valve opened or close.Move with wiping action owing to revolving between front cover, and the contact with flowing medium can be prevented completely when standard-sized sheet, therefore the medium that usually also can be used for suspended particulate, another key property of stopcock is easy to adapt to multi-channel structure, so that a valve can obtain two, three, even four different six roads, the design of pipe-line system can be simplified like this, reduce some connection fittings needed in valve consumption and equipment, the shape of the valve plug of stopcock can become cylindrical or conical, stopcock is best suited for as cut-out and connects medium and shunt applicable.
Present use stopcock complicated operation, inconvenient, after valve Long-Time Service, cannot have good sealing effect, the poor-performing of resistance to deflation, maintenance cost is comparatively large simultaneously, needs often to change component, reduces working efficiency and increases cost of production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of lubricating type stopcock of good sealing effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lubricating type stopcock, there is valve body and valve seat, be bolted between described valve body and valve seat, valve seat offers inlet and outlet port, oil fill plug is provided with in valve body, oil fill plug is connected with valve rod, valve rod is connected with safety check, safety check reduces friction, reduce rapid operation, valve rod is connected with cock, seat bottom portion is flatness, seat bottom portion is without groove, foreign material are not easily caused to deposit, the sidewall of valve seat offers oil storage tank, the surface spraying of valve body and valve seat has epoxy resin layer, in valve body and valve seat, outer employing avirulent powder, strengthen corrosion resistance, improve feed water quality.
Further, described oil fill plug is provided with " O " RunddichtringO, seal ring significantly can reduce water leakage phenomenon.
Further, described valve seat and the joint of valve body are provided with stuffing box packing, and produce enough seal pressures, sealing pair reaches zero leakage.
Further, described valve body and valve seat adopt carbon steel, alloyed steel or stainless steel material to make, and are applicable to the severe rugged environments such as corrosivity, severe toxicity and high harm medium.
The invention has the beneficial effects as follows: structure of the present invention is simple, operation and easy to use, still have good sealing effect after Long-Time Service, often need not change component, maintenance cost is cheap, and reduction cost of production, increases work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. valve bodies, 2. valve seat, 3. inlet, 4. outlet port, 5. oil fill plug, 6. safety check, 7. valve rod, 8. epoxy resin layer, 9. oil storage tank, 10. cock in figure.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of lubricating type stopcock as shown in Figure 1, there is valve body 1 and valve seat 2, be bolted between valve body 1 and valve seat 2, valve seat 2 offers inlet 3 and outlet port 4, oil fill plug 5 is provided with in valve body 1, oil fill plug 5 is connected with valve rod 7, valve rod 7 is connected with safety check 6, valve rod 7 is connected with cock 10, it is flatness bottom valve seat 2, the sidewall of valve seat 2 offers oil storage tank 9, the surface spraying of valve body 1 and valve seat 2 has epoxy resin layer 8, oil fill plug 5 is provided with " O " RunddichtringO, valve seat 2 is provided with stuffing box packing with the joint of valve body 1, valve body 1 and valve seat 2 adopt carbon steel, alloyed steel or stainless steel material are made.
Concrete cock body rotates with valve rod 7, to realize switching motion, lubricating grease injects valve body 1 from oil fill plug 5 top, forms oil film to reduce to open and close moment, improve sealing and working life, structure is simple, operation and easy to use, still has good sealing effect after Long-Time Service, often need not change component, maintenance cost is cheap, reduces cost of production, increases work efficiency.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
