The feature of utility model is to set the non-return device inside water outlet of valve cap, the non-return device comprise valve clack rod and valve clack, valve clack rack, pressure spring, check ring and perforated baffle connected with valve clack rod, the angle valve with non-return device cannot only keep start-stop function of angle valve but also have non-return function to avoid liquid reversible flow, with two functions, the valve function has perfect, the cost of installing angle valve water outlet is saved, the water outlet pressure of this valve is greater than water inlet pressure and desire the pipeline with non-return function.
Description
Technical field
The utility model relates to a kind of angle valve, has the nonreturn type angle valve of check device specifically.
Background technique
Angle valve is a kind of keying valve commonly used, usually be applied in and cut, the occasion that the draining right angle connects, or in the various tank pipes, the angle valve of Shi Yonging only has the effect of stop valve in the market, when water outlet pressure is cut off the water greater than water intake pressure or pipeline, the water in outlet port can pass back in the angle valve, for anti-backflow, connect a safety check again at the angle valve water outlet usually, though do the problem that water refluxes that solved like this, also improved but cost is corresponding, if when installing and using, want two valves to install together toward contact, very trouble, and this angle valve function singleness, can't satisfy user's usage requirement.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of cost low, and is easy to install, and has the nonreturn type angle valve that dams with the non-return dual functions.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of nonreturn type angle valve, it comprises valve body, be connected the valve gap on the valve body, be provided with the spheroid of valve seat and opening/shutting valve in the valve body, valve body is provided with to be tightly connected with it realizes the operating component of valve opening and closing, it is characterized in that described valve gap is provided with check device in water outlet, this device comprises the flap bar of being with omoplate, the upper end of flap bar is provided with the back-up ring and the perforated baffle of axially locating, be provided with pressure spring between perforated baffle and flap bar omoplate, the lower end is provided with by the flap of the fastening opening/shutting valve of nut and valve petal shelf.
The back-up ring of described axially locating is embedded in associated valve gap inner groove.
It is that be in transmission connection with spheroid, axial by shoulder valve rod spacing, that be provided with two roads " O " RunddichtringO in the valve body that the operating component of described opening/shutting valve comprises, knob is installed on the valve rod that is in transmission connection with it, and fixes by screw axial.
Described valve inleting water end is provided with trim.
Compared with prior art, the utility model is provided with check device in the valve gap water outlet, not only keep angle valve and opened and closed the function of damming, also has the function that prevents liquid return, one valve is dual-purpose, and the cost that the angle valve waterexit end is installed safety check has again been save in Perfect in shape and function, make installation, use more conveniently, this valve is applied in water outlet pressure greater than water intake pressure and require to have in the pipeline of check function.
Description of drawings
Fig. 1 has provided structural representation of the present utility model.
Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As shown in Figure 1, the nonreturn type angle valve, by valve body 1, valve gap 2, spheroid 3, valve seat 4, realize the operating component of valve opening and closing, formations such as check device, valve body is connected with thread seal with valve gap, the spheroid of opening/shutting valve is located in the valve seat in the valve body, and valve seat is by the interior shoulder location of associated valve body and valve gap.The operating component of realizing valve opening and closing is installed on the center line of pipeline intake tunnel, form by valve rod 12, " O " RunddichtringO 13, screw 14, knob 15, valve rod axially spacing by shoulder in the valve body, one end are gone into flat pivot pin to form in the flat groove of spheroid 3 and are in transmission connection; The other end connects knob with arcuation quadrilateral head cover, and axially fastens by screw 14, prevents that knob breaks away from valve rod, and rotary knob can be realized valve opening and closing or regulating valve size on demand, is illustrated as valve opening state.Sealing between valve rod and the valve body is by being located at two roads " O " RunddichtringO, 13 sealings on the valve rod.
Be provided with check device in the described valve gap water outlet, this device comprises the flap bar 8 of being with omoplate, this flap bar upper end is provided with the back-up ring 5 of axially locating, back-up ring is the annular shape of openings at one side, be embedded in the inner groove of associated valve gap 2, what nestle up back-up ring is perforated baffle 6, is provided with the pressure spring 7 of a pagoda shape between perforated baffle and flap bar omoplate, its stub end withstands on the perforated baffle, and little head end withstands on the flap bar omoplate; Flap bar lower end is set with inverted cone bench-type flap 10 and supports the valve petal shelf 9 of flap, and is fastened by nut, when the conical surface of flap during with the sealing of valve gap inner headed face interruption-forming, promptly stops the backflow of the interior current of outlet conduit.
When the nonreturn type angle valve uses, drive spheroid 3 conducting water-in and water-out pipelines by knob 15, under the intake pipe water flow pressure, flap in the check device promotes valve petal shelf and makes the pressure spring compression, because back-up ring tightly is embedded in the valve gap inner groovy, block axially scurrying out of perforated baffle 6 and pressure spring 7, so the gap occurs between flap and the valve gap valve port, current just flow to water outlet from the gap.When water outlet pressure was closed greater than water intake or angle valve spheroid 3, under the precompression of pressure spring, flap 10 was sealed water outlet again, the backflow of anti-sealing.
The non-return structure of nonreturn type angle valve, also can be applied in the valves such as gate valve, ball valve, stop valve, play the dual-purpose effect of a valve, this valve only allows liquid to reflux to the direction circulation and the prevention of regulation, therefore be widely used in building, in the water circuit system of food and hot-water heating health etc., also can be applicable to do in the pipe-line system of other non-aggressive medium one-way valve and use, as make small-sized water storage container inlet valve or in the pressure transient pipeline, not only can play the non-return valve action but also make things convenient for opening and closing.Needs according to the user also can be provided with trim 11 outside intake pipe.
