Abstract
The utility model discloses a high pressure regulating valve body, which comprises a valve in a whole forging, an inlet transitional nozzle and an outlet transitional nozzle. The path of the transitional nozzles is matched with the nominal path of the valve body. An end of the path is processed into an integral flange or a thread flange, which is connected with the valve body through a bolt and a lens gasket is arranged for sealing at the connection joint. The utility model has the advantages of excellent compressive strength, minimum material, simple process, and low cost.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of high-pressure regulation valve body.
Background technique
At present, the septum valve that in high pressure (more than the 32Mpa) system, uses, its valve body (seeing Fig. 1, Fig. 2) is many to process with the cast steel base, and defectives such as bubble, burning into sand are arranged unavoidably, causes body strength to reduce, and stays accident potential.Therefore, the whole forged steel base processing of the also use that has valve body.But the two ends flange diameter is very big because the size in valve body stage casing is less, and the size of forged steel base must be forged by flange size, and technology difficulty is very big when causing gold machining, and bite is also very big, and waste material, cost are very high.
The model utility content
The purpose of this utility model provides a kind of compressive strength height, consumes the septum valve forged steel valve body that material is few, processing is simple, with low cost.Technological means is not establish the flange of direct connecting tube on valve body, and take over for it with the inlet/outlet transition, the end that the transition adapter is connected with valve body is managed orchid, but the diameter of this flange is just very little, basic identical with valve body, the other end of adapter needs to be processed into flange according to usage requirement and connects, is welded to connect or screw connection structure.Concrete technical solution is as follows:
A kind of high-pressure regulation valve body is characterized in that: comprise the valve body and the inlet/outlet transition adapter that are processed by solid forging respectively; The latus rectum that described transition is taken over and the inside nominal diameter of valve body are suitable, and its end is processed into integral (type) flange or screwed flange, are connected with valve body by bolt, and joint is provided with the sealing German-style metal lensring.
The beneficial effects of the utility model are, the compressive strength height, consume that material is few, processing is simple, with low cost.
The utility model is described in detail in detail below.

Fig. 3 is the structural drawing of angle of the present utility model stroke high-pressure regulation valve body;
Fig. 4 is the structural drawing of straight journey high-pressure regulation valve body of the present utility model.
Embodiment
One jiao of stroke high-pressure regulation of embodiment valve body
Referring to Fig. 3: this high-pressure regulation valve body comprises that valve body 2, inlet/outlet transition take over 1, German-style metal lensring 3, bolt and nut pay 4,5.
The latus rectum of transition adapter 1 and the inside nominal diameter of valve body 2 are suitable.
One end of transition adapter 1 is processed into flange, and is connected with valve body 2 by bolt and nut pair 4,5; Also can process screw thread and be connected with flange, flange is connected with valve body 2 again.Transition is taken over 1 the other end and is processed weld bond or screw thread as required, or docks welding with pipeline, or installs flange additional and be connected with piping flange.
Screw on the valve body 2 is symmetrical arranged, promptly convenient processing, and making the inlet/outlet transition take over 1 again can exchange, the convenient use.
Embodiment's two straight journey high-pressure regulation valve bodies
Referring to Fig. 4: this example is compared with embodiment one, in valve body 2 different with the structures of spool auxiliary section, all the other are identical, so will not give unnecessary details.
