Summary of the invention: technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of energy-conservation, operational torque is little, working life is long throttling stop valve is provided.
The utility model is that the following technological scheme that adopted that achieves the above object is: a kind of balanced type throttling stop valve, comprise valve body, valve seat, valve gap, flap, valve rod and flap lid, it is characterized in that: described balanced type throttling stop valve is coaxial on the direction that flap promote to be opened to be provided with a cylindrical openings die cavity, and described flap cross section and the cross section of die cavity are made into the close airtight counter balance pocket of its formation that makes movingly and along wherein sliding of liquid mutually; Described balanced type throttling stop valve also is provided with the communication balance channel, and throttling stop valve is in off position the time, and described communication balance channel is communicated with counter balance pocket and snout cavity.
As further setting of the present utility model: the bottom of described valve gap is a cylinder-like structure, the valve gap intracavity section becomes with the flap cross section that liquid is close to constitute described counter balance pocket movingly, tubular inner chamber roof is provided with the through hole that cooperates with the valve rod motive sealing, and described valve rod passes from through hole; Described valve rod and flap are provided with cross-drilled hole and axial pipeline constitutes described balance channel.
Further be provided with as of the present utility model: described valve gap has flange for the middle part outer wall, the member that up-small and down-big two cylindrical sections are formed, valve gap installation cavity internal diameter vertical on the lower outer diameter of flange and the valve body cooperates, be provided with dividing plate between two sections inner chambers of valve gap two sections are separated into filler storage chamber and counter balance pocket, the dividing plate center is provided with the through hole that cooperates with the stem diameter motive sealing, valve rod therefrom passes movingly, being connected of upper end with handwheel, the lower end is connected with the flap concentric, the filler storage is inserted filler in the chamber, the outside is provided with the annular packing gland, and Gland is threaded with valve gap top and the axial compression Gland.
Further be provided with as of the present utility model: be equipped with " O " RunddichtringO on the described annular packing gland inside and outside wall.
Further be provided with as of the present utility model: also be provided with the horizontal pin-and-hole that connects with rack bore on the described support, throttling stop valve is when opening and closing, respective pin hole projected footprint place thereon is provided with the longitudinally guiding groove on the stem surface, be inserted with guide finger in the pin-and-hole, the inner falls into guiding groove.
The beneficial effects of the utility model are: because a side of promote opening at flap is provided with counter balance pocket and is communicated with snout cavity by balance channel, in the moment of opening and closing, pressure at both sides balance unanimity has been eliminated pressure difference before and after the flap, therefore alleviate operational torque, reduced energy consumption.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
Description of drawings:
Fig. 1: the utility model example structure sectional view.
Embodiment: as shown in Figure 1, similar with existing throttling stop valve, the balanced type throttling stop valve still includes valve body 2, valve gap 9, flap 4, valve seat 3, valve rod 5, support and handwheel 22 etc., valve body 2 is provided with a snout cavity 13 and outlet plenum, be provided with the connecting port of a level between snout cavity 13 and the exit port, flap 4 is connected with handwheel 22 through valve rod 5 and is bearing on the support, valve gap 9 has the member that up-small and down-big two cylindrical sections of flange are formed for the middle part outer wall in the utility model, valve gap 9 installation cavity internal diameters vertical on the lower outer diameter of flange and the valve body 2 cooperate, be provided with dividing plate between 9 two sections inner chambers of valve gap two sections are separated into filler storage chamber 14 and counter balance pocket 1, the dividing plate center is provided with the through hole that cooperates with valve rod 5 diameter motive sealings, valve rod 5 therefrom passes movingly, being connected of upper end with handwheel 22, the lower end is connected with flap 4 concentrics, described flap 4 is cylindricality substantially, external diameter becomes liquid movingly close with counter balance pocket 1 internal diameter, can in counter balance pocket 1, slide up and down, there is an annular sealing surface that matches with valve seat 3 lower end, the height of flap 4 will satisfy when valve is in closed condition top and still have partly and fall within the counter balance pocket 1, the degree of depth of counter balance pocket 1 should leave flap 4 and promote the displacement that valve is fully opened, on the valve rod 5 near with flap 4 joints one cross-drilled hole and downward vertical core being set and being communicated with formation balance channel 12 with flap 4 axial pass-through holes, certainly, the setting of balance channel 12 neither be unique, gets final product with snout cavity 13 so long as can be communicated with counter balance pocket 1 hermetically when the throttling stop valve closed condition; In addition, also be provided with the horizontal pin-and-hole 19 that connects with rack bore on the support, throttling stop valve is when opening and closing, valve rod 5 surfaces are gone up respective pin hole projected footprint place thereon and are provided with longitudinally guiding groove 23, be inserted with guide finger 21 in the pin-and-hole, the inner falls into guiding groove 23, prevents valve rod 5 and flap 4 rotations when opening and closing, and sealing pair produces friction; The filler storage is inserted composite filling 20 in the chamber 14, the outside is provided with annular packing gland 17, Gland 18 is threaded with valve gap 9 tops and axial compression Gland 18, in order further to improve sealability, on valve gap 9 and filler gland 17 inside and outside walls, all also be provided with several " O " RunddichtringO 15,16.
