A corrosion resistant iron casting is used by the valve body of the utility model so that failure rate is reduced, and service life is extended.

Description

Pipeline shunting saddle valve

What the design related to is the part flow arrangement that transports the pipeline of fluid thing, particularly pipeline shunting saddle valve.

According to new use needs, to carry out open split be common occurrence to burying pipeline that (applying) establish.When the preceding pipeline shunting does not particularly still have special-purpose part flow arrangement to the shunting of underground pipeline, generally all adopt a pipe collar, two valves and three straight-through tubes, (as shown in Figure 1) that the elbow stack mounting realizes, this has not only increased cost, also be not easy to installation and rate of breakdown height, strengthened the maintenance and repair workload.

The design's purpose provides a kind of part flow arrangement that is exclusively used in the shunting of transporting the fluid conduit, to overcome the deficiency of prior art.

The design's purpose is achieved through the following technical solutions.

A kind of saddle valve that is exclusively used in pipeline shunting has valve body that epicoele communicates with cavity of resorption and two chambeies, split-flow opening that communicates with epicoele, interface that communicates with cavity of resorption, valve gap and one by a saddle seat that is connected to a fixed with pipe collar, one and runs through the screw rod that valve gap and its lower end enter epicoele and formed with a briquetting that is connected with the screw rod lower end.

Use the pipeline shunting saddle valve of said structure not only to be convenient to install, it is simple and compact for structure, and cost is low, and its valve body can adopt corrosion resistant ironcasting, has prolonged working life thereby reduced rate of fault.

Below in conjunction with accompanying drawing the design is further described in detail.

Fig. 1 is the existing shunt structure diagrammatic sketch that the shunting of underground pipeline is adopted

Fig. 2 is the design's configuration diagram

Fig. 3 is a saddle seat worm's eye view

Three-dimensional diagrammatic sketch when Fig. 4 is installed on the main pipe for the design

Among Fig. 1: (1) is valve, and (2) are pipe collar, and (18) are straight-through tube, and (19) are elbow, and (20) are ram's horns, and (21) are main pipe.

With reference to Fig. 2,3, the design is made of saddle seat (3), valve body (6), split-flow opening (7), interface (8), valve gap (9), screw rod (10), briquetting (11) and hexagon nut (15) and seal ring (16), wherein:

Saddle seat (3) is in the base of saddle valve, it can with valve body (6) cast solid, relatively respectively has a fixedly circular hole (12) that can be connected with pipe collar (2) in its both sides, the lower edge of both sides, front and back in the middle is arcuation, the body radian of its radian and main pipe adapts, like this when the saddle valve by pipe collar (2) with when fixedly circular hole (12) is fixed on the main pipe that needs shunting, make adaptation is preferably arranged between the two, in order to reach good leak preventing effect, between also accompanies a leak-proof gasket (not drawing among the figure), and this packing ring generally is to make with rubber-like materials such as rubber.

Valve body (6) has cavity of resorption (4) and epicoele (5) and two chambeies and communicates, and wherein epicoele (5) is greater than cavity of resorption (4), and this valve body can be made ironcasting by casting technique, and because of ironcasting thickness is big so corrosion-resistant, and cost is low.Can certainly adopt stainless steel material or other material.

Split-flow opening (7) communicates with epicoele (5), and on same horizontal line, this split-flow opening can be connected with ram's horns at the bottom of the chamber of its bore lower edge and epicoele (5).

Interface (8) communicates with cavity of resorption (4), and middle part through saddle seat (3), in fact, this interface is exactly the mouth that opens wide downwards of cavity of resorption (4), cavity of resorption (4) is generally cylindrical cavity, natural interfaces (8) is a circular port just also, and is apparent, and the circle footpath of interface (8) should be less than the pairing diameter of radian of two of above-mentioned front and back, saddle seat (3) middle part.

Its upper end of valve gap (9) is a hexagon, and its lower end is goed deep into to epicoele (5), and is connected with valve body (6) by screw thread (13).

Screw rod (10) runs through from the upper end of valve gap (9) and goes into, and its lower end enters epicoele (5), and this screw rod is connected with valve gap (9) by screw thread (14).Rotatory handling can be installed in upper end at this screw rod, and this rotatory handling of turn can be realized the lifting of this screw rod by screw thread (14), thereby controls the keying of saddle valve.

Briquetting (11) is connected with the lower end of screw rod (10), and its greatest circle is directly worked energetically the chamber footpath of cavity of resorption (4) and directly adapted with the chamber of epicoele (5).This briquetting adopts copper material to cast, and also can adopt whippy material, as material such as rubber.When screw rod (10) descend make this briquetting press the chamber of epicoele (5) at the bottom of the time, the saddle valve is closed condition, otherwise is opening state.This briquetting is connected with screw rod (10) lower end, can adopt screw to connect or the alternate manner connection.

In order to make the saddle valve that good sealing property be arranged, unlikely generation leakage phenomenon, this saddle valve also design a hexagon nut (15) and seal ring (16), and this nut is connected with valve gap (9) by screw thread (17).A circle copper material (22) simultaneously also entirely distributes in the bottom of epicoele (5), this has just overcome valve body (6) makes the defective that cylinder iron gets rusty easily, even through using for a long time, briquetting in the time of also guaranteeing throttle down (11) has good adaptation with the bottom of epicoele (5) like this.

For adapting to the main pipe of different size bore, the design can manufacture and design the series product of different size.

With reference to Fig. 4, on the main pipe (21) of needs shunting place, open a draining hole that adapts with above-mentioned interface (8), select the design's of adapting with it specification product, leak-proof gasket on the pad utilizes pipe collar (2) to be fixed to be installed in and can realize shunting purpose on the draining hole.
