Problems solved by technology

[0002] Valves are widely used in industry, but they have the following disadvantages in actual use: only one-way flow of the medium is allowed, and there is directionality during installation; the cost of the valve is high, and the function is single; when the fluid resistance is large, the valve is not easy to open and close, and is not suitable for frequent switching Action; poor sealing effect when used in granular, viscous, coking fluid media

Embodiment Construction

[0026] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0027] Such as Figure 1~6 As shown: the large-diameter stop valve of the present invention includes a valve body, a balloon 3 and a gas pipe 8. The valve body is formed by screwing the main valve body 6 and the valve cover 1. The valve body is provided with a retaining ring 2 and a support ring 5, the support ring 5 is fixed in the main valve body 6, and the retaining ring 2 is set between the main valve body 6 and the valve cover 1 (such as Figure 5 and Figure 6 As shown: the center of the baffle ring 2 is set as a spherical surface, and the cut-off function of the balloon 3 is supported on the baffle ring 2 after it is inflated). 6, located between the stop ring 2 and the support ring 5 (such as figure 2 As shown: the balloon 3 is fastened on the trachea 7 through the fixing sleeve 4), and one end of the trachea 7 passes through the central hole 13 of t...

Abstract

The invention relates to a shutoff valve with a large drift diameter, and belongs to the application field of valves. The shutoff valve with the large drift diameter comprises a valve body, a balloon and a gas pipe, wherein the balloon is arranged inside the valve body; the balloon is connected with a gas source through the gas pipe; the valve body is formed by connecting a main valve body and a valve cover through threads; a supporting ring is arranged inside the main valve body; a baffle ring is arranged between the main valve body and the valve cover; the balloon is arranged between the supporting ring and the baffle ring; the balloon is fixed on the supporting ring through the gas pipe; an electromagnetic valve and a pressure transmitter are installed on the gas pipe; a flow meter is arranged on an outlet pipe of the valve body; the flow meter and the electromagnetic valve are connected to a control device; and the control device regulates flow by controlling opening and closing of the electromagnetic valve. The balloon is installed inside the valve body, so that the shutoff valve with the large drift diameter is simple in structure and has no requirement on one-way flowability; action of the valve is realized by inflating and deflating the balloon, so that the shutoff valve with the large drift diameter is labor-saving, easy and convenient to operate, good in regulating performance and easy to realize automatic control; the balloon can be made of different materials, so that the shutoff valve with the large drift diameter is applicable to conveying of various media.

Description

technical field [0001] The invention relates to a valve, in particular to a large-diameter stop valve, which belongs to the application field of valves. Background technique [0002] Valves are widely used in industry, but they have the following disadvantages in actual use: only one-way flow of the medium is allowed, and there is directionality during installation; the cost of the valve is high, and the function is single; when the fluid resistance is large, the valve is not easy to open and close, and is not suitable for frequent switching Action; when used in granular, viscous, coking fluid media, the sealing effect is poor. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a large-diameter stop valve with simple structure, labor-saving and convenient operation, good adjustment performance, and suitable for the transportation of various media. [0004] The tech...
