Abstract
A through type stop valve comprises a spool and a plastic valve body consisting of a right-angle tee joint. An inlet pipe and an outlet pipe of the right-angle tee joint are positioned on the same axis, a copper sleeve is embedded into a vertical pipe of the right-angle tee joint, and an arched section is arranged at the top of the inner end of the outlet pipe. By means of the design of the valve body, the upward arched section is formed above the outlet pipe, so that the flow area of the arched section is enlarged, and the resistance of fluid flowing through the valve body is decreased. The through type stop valve has the advantages of simple structure, convenience in manufacture and small fluid resistance.
Description
Technical field
The utility model relates to Low pressure valve, particularly the logical little manually operated type stop valve of resistance of current.
Background technique
The valve body of existing straight-through type water valve adopts the right-angle tee form for one section.When if intake pipe and outlet pipe are positioned at same axis; The circulation area that preceding manger board (it highly is into water water pipe radius) in the valve body is located is generally the half the of intake pipe circulation area; The circulation area that back manger board (it highly equals water outlet pipe radius) is located in the valve body is half the also littler than outlet pipe circulation area, and therefore, the fluid resistance that back manger board place forms is maximum; The water-outlet quantity of whole valve is restricted (the applicant's patent " the plastics valve body of straight-through plastic valve ZL201020204651.X is the right-angle tee form; its intake pipe is vertical with outlet pipe, in this case, above-mentioned bottleneck problem can not occur).
The model utility content
The purpose of the utility model provides the little manually operated type stop valve of a kind of circulating resistance.
This novel purpose is achieved in that a kind of straight-through stop valve; Comprise spool; The plastics valve body, the plastics valve body is made up of a right-angle tee, and the inlet tube of this right-angle tee and outer pipe are positioned at same axis; Be embedded with copper sheathing in the vertical tube of this right-angle tee, and an arch camber section is arranged at the inner top of outer pipe.
Above-mentioned inlet tube and outer pipe are provided with internal thread.
Above-mentioned valve core structure is: valve rod is screwed in the valve core housing, and the valve core housing bottom is fixed with sealing gasket, and valve gap is connected with said copper sheathing spiral, and valve core housing is positioned at valve gap, is provided with seal ring between valve gap top and the valve rod.
Compared with prior art, the utlity model has following characteristics and advantage:
1, when the three-way valve form a right angle, the inlet and outlet pipes in the same axis, the valve body and the tailgate outlet tube above the top of the valve body end of the minimum flow channel, and the use of this valve is designed so that upward is formed above the outlet tube bagging section, thereby increasing the flow area at the narrow Yi, reducing the resistance to fluid flow through the valve body.
When 2, making, be convenient to adopt tiltedly that the mode of loosing core makes valve outlet pipe place form oblique finding time, then, adopt milling machine to mill remaining part again, and form the outer pipe that is positioned at same axis with inlet tube.
3, this valve brings reducing of fluid resistance with less change aspect manufacturing, thereby, on the original basis, do not increase the processing and fabricating cost basically, be easy to promote.
Description of drawings
Fig. 1 is this novel structural drawing.
Fig. 2 is the sectional drawing of Fig. 1 along the A-A line.
Embodiment
Fig. 1 illustrates; Basis is novel to be made up of spool and plastics valve body etc.; The plastics valve body is made up of a right-angle tee; The inlet tube 1a and the outer pipe 1b of this right-angle tee are positioned at same axis, are embedded with copper sheathing 4 in the vertical tube 1c of this right-angle tee, and an arch camber section 1d (formation arch) is arranged at the inner top of outer pipe 1b.Referring to Fig. 2, lower semisection is the half the of a standard circular among Fig. 2, and the inner arch camber section 1d of outer pipe is the top that is positioned at original upper semi-circle, the formed part that upwards arches upward.
Among the embodiment 1, inlet tube internal diameter 24mm, the circulation area of front screen 1e below is half the (distance of front screen and below tube wall is 12mm) of inlet tube circulation area; Distance between front screen and the backboard 1f is 17mm; The vertical tube internal diameter is 24mm, and the anterior internal diameter of outer pipe is 24mm, and the distance between outer pipe rear end and the backboard top is 16mm; If do not adopt the arch camber part, then this place's distance has only 8-9mm.Inlet tube 1a and outer pipe 1b are provided with internal thread.Valve body can adopt with being connected of plastic water pipe and be threaded, and also can adopt heat-shrink tube to connect, and also can adopt welding.
Valve core structure is: valve rod 2a is screwed in the valve core housing 2b, and the valve core housing bottom is fixed with sealing gasket 2c, and valve gap 2d is connected with said copper sheathing 4 spirals, and valve core housing 2b is positioned at valve gap, is provided with seal ring 5 between valve gap 2d top and the valve rod 2a.The valve rod roof anchorage has handle 3.
