Problems solved by technology

Because carbide alloy materials are extremely expensive and scarce in the current market, objectively speaking, this production method of using expensive carbide alloy materials to make throttling parts as a whole is also extremely uneconomical and reasonable. Excessive consumption of valuable carbide alloy materials will not only cause a huge waste of precious carbide alloy materials, but also greatly or even increase the production cost of high-pressure throttle valves several times, which will eventually lead to It is difficult for users to accept the use. In fact, there have been no literature reports on the use of natural gas in the transmission and distribution industry.

Abstract

The invention discloses an anti-scouring and anti-corrosion high-pressure throttling valve of a throttling structure formed by a combined sleeve and a combined valve element, and a producing method of the combined valve element. The anti-scouring and anti-corrosion high-pressure throttling valve is remarkably and structurally characterized in that the combined sleeve is composed of an upper cylinder and a throttling sleeve which are tightly matched and embedded, the combined valve element is formed by connecting an upper core body with a throttling core through a pin shaft by means of the hot-pressing technology, and a throttling cone shaft of the throttling core forms a reducing conical passageway throttling structure in a throttling hole. The throttling sleeve, the throttling core and a valve seat making contact with high-speed flowing gas media are made of hard alloy materials, and therefore high-speed gas flow scouring can be effectively resisted and borne, and the anti-scouring performance and anti-corrosion performance are improved. The throttling valve has the outstanding advantages of being simple in structure, easy to produce, capable of saving alloy materials and reducing manufacturing cost, high in anti-scouring capacity and anti-cavitation capacity, long in service life, and good in energy conservation and emission reduction effect, is particularly suitable for installing high-pressure gas conveying pipelines with pressure of 20 MPa or higher in the petrochemical industry, and has quite high application and popularization prospects.

Description

technical field [0001] The invention relates to a high-pressure throttle valve and an assembly production method, belonging to the technical field of gas transmission pipeline network control equipment, in particular to a production method of a high-pressure throttle valve with erosion resistance and corrosion resistance and a combined valve core. It is especially suitable for installation and use on high-pressure gas pipelines above 20MPa. It has the outstanding advantages of high pressure bearing capacity, strong erosion and corrosion resistance, safe and stable operation, and long working life. Background technique [0002] We know that the high-pressure transmission of natural gas is the best collection and transportation method to improve the transportation efficiency of gas transmission pipeline network equipment. The pressure operation will reduce it to the rated air pressure, and then deliver natural gas with qualified pressure to the user for safe use. The throttle...
