Abstract
The utility model discloses a self-compensation type elastic rotary valve which is composed of a valve body and a valve cover arranged on the valve body. The valve cover and the valve body are connected through a connection screw, a washer is arranged on the screw, a lower valve rod is arranged on the valve body, the upper end of the lower valve rod is connected with an upper valve rod, and a clamping spring and a washer are arranged between the lower valve rod and the valve body. The valve is further provided with an O-shaped sealing ring, a round pin is arranged at the lower end of the lower valve rod, a valve core piece is arranged on the round pin, and a ladder-shaped spring is further arranged between the round pin and the valve core piece. The self-compensation type elastic rotary valve is suitable for cold-warm water projects and central air-conditionings.
Description
Technical field
The utility model relates to a kind of electric ball valve, especially relates to a kind of autocompensation type elasticity rotary valve.
Background technique
In the HVAC engineering; Electric ball valve is the raising of a vitals, particularly automaticity, controls automatically; The electric ball valve of ability autocompensation type occupies more and more important in the position; The Hydraulic Power System electric control valve of overall balance also is widely used in the fluid control member of systems such as central air-conditioner, heating, water treatment, industrial processes industry, and require increasingly high, environmental protection, energy-conservation, efficient.The present existing shortcoming of electric ball valve on the market mainly is that automatic regulatory function is not enough, and valve seal property difference is prone to leak, and is perishable, is prone to incrustation.
Summary of the invention
The purpose of the utility model is to be directed against the shortcoming that above-mentioned electric ball valve is deposited, and provides a kind of design more rational, automatically the strong autocompensation type elasticity rotary valve of regulatory function.
In order to achieve the above object, the utility model mainly adopts following technological scheme to realize.The utility model mainly is made up of the valve body of autocompensation type elasticity rotary valve and the valve gap of being located on the valve body, and valve gap connects with being connected screw with valve body, and screw is provided with pad; On valve body, be provided with lower valve rod, the upper end of lower valve rod connects upper valve rod, is provided with jump ring and pad between lower valve rod and the valve body; Also be provided with the O RunddichtringO; Lower end at lower valve rod is provided with round pin, and round pin is provided with Valve core blade, between round pin and Valve core blade, also is provided with trapezoidal spring.
The utility model compared with prior art has following tangible advantage and innovation.(1) valve rod of the utility model has two, is divided into upper valve rod and lower valve rod, and in use valve rod can play self-adjusting effect.(2) the utility model torsion is little, and shut off differential pressure is big, and the cipher telegram performance is good, is not easy scaliness.(3) energy consumption is low.The utility model adopts low voltage 5V dc powered.
The utility model is suitable for changes in temperature water conservancy project journey and central air-conditioner uses.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model overall structure cut-away view.
Embodiment
As shown in the figure, the utility model mainly is made up of the valve body 11 of autocompensation type elasticity rotary valve and 6 of the valve gaps of being located on the valve body 11, and valve gap 6 is connected screw 3 and connects with valve body 11 usefulness; Connect screw 3 and be provided with pad 4; On valve body 11, be provided with lower valve rod 2, the upper end of lower valve rod 2 connects upper valve rod 1, is provided with jump ring 5 and pad 7 between lower valve rod 2 and the valve body 11; Also be provided with the O RunddichtringO; Be provided with round pin 10 in the lower end of lower valve rod 2, round pin 10 is provided with Valve core blade 8, between round pin 10 and Valve core blade 8, also is provided with trapezoidal spring 9.
The utility model is suitable for changes in temperature water conservancy project journey and central air-conditioner uses.
