SK285467B6 - T-valve and double-way valve under manometer - Google Patents

Abstract

Three-way and two-way valve below manometer consists of a body of a valve and a closing mechanism that is created by a closing unit and a control handle. The closing unit (1) is shaped like a keg with channels (2) and is fixed into teflon rings seals (3) cold formed and this closing unit (1) is coupled with a control handle (4). The teflon rings seals (3) are placed into a body of a valve (5) as well as in an output interlink (6), eventually in an exhauster interlink (7). The output interlink (6) and the exhauster interlink (7) are non-rotary demountable placed in a body of the valve (5).

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a three-way and two-way valve under a manometer intended to close a pipeline for liquids and gases including oxygen.

BACKGROUND OF THE INVENTION

The two-way and three-way pressure gauge valves used to close the pipeline, mainly gas, have been used in the market for the most part tapered, ie metal in metal. The sealing effect is achieved by pulling one component towards the other, either from above or below. At the same time, a relatively high friction occurs on the contact surfaces of the functional components. This entails the necessity of lubrication and therefore these valves are not applicable, for example, to oxygen.

Needle valves are used to seal gas pipes, especially oxygen, under pressure gauges. They include a classic body with a seat that fits a plug, which is operated by a handwheel to open and close the valve. The disadvantage of the seat-cone system is its demanding workmanship and the significant disadvantage is its functional limitations - they can only be manufactured as two-way. If the effect of the three-way valve is to be achieved, it can be replaced by a combination of two needle valves, which is neither a practical nor an economically attractive solution.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages and drawbacks of the known gas and liquid line valves are largely eliminated by the three-way and two-way valves under the pressure gauge according to the invention, consisting of a valve body and a closing device consisting of a closing member and an operating handle. The principle of the invention is that the valve closure member is in the form of a barrel equipped with channels and seated in cold-formed teflon gaskets and that the closure member is connected to the control handle and the adjacent teflon gaskets are housed in the valve body as well as the outlet the intermediate member, optionally in the vent intermediate member, and the intermediate members are non-rotatably disassembled in the valve body.

The three-way and two-way valve under the pressure gauge according to the invention preferably has a closing member made of a metal material, preferably of brass or stainless steel, as well as a valve body.

The closure member is preferably secured in the valve body by a nut in which it is sealed by a rubber seal and the nut is sealed in the valve body by a rubber seal and secured by a sealant.

The advantages of the three-way and two-way valves according to the invention over the previously used valves are low friction-free lubrication, high-efficiency gaskets and easy operation, thus enabling universal use. The relatively low production costs and the long service life also favor the solution of the valve according to the invention, which translates into the considerable economic advantage of the solution.

BRIEF DESCRIPTION OF THE DRAWINGS

Examples of a three-way and two-way valve according to the invention are illustrated in the accompanying drawings, in which:

FIG. 1, 2, 3 - side view, front view and plan view of the three-way valve - in axial section;

Fig. 4, 5, 6 - side view, front view and plan view of the two-way valve - in axial section.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

FIG. 1, and in particular FIG. 2 shows that the three-way valve has a barrel-shaped closing member 1 equipped with channels 2 and seated in a cold-formed teflon seal 3 and that the closing member 1 is connected to the control handle 4. The annular teflon seals 3 are housed in the valve body 5 as well as the outlet intermediate 6 and the vent intermediate 7 are both screwed into the valve body 5. The outlet intermediate is oriented in the direction of the valve body 5 and the vent intermediate 7 is perpendicular to this direction. Accordingly, channels 2 are formed in the closure member 1, as shown in FIG. 3. The discharge intermediate member 6 and the deaeration intermediate member 7 are sealed in the valve body 5 by a rubber seal and secured with a sealant. The closure member 1 is secured in the valve body 5 by a nut 7 in which it is sealed with O-rings and this nut 7 is sealed in the valve body 5 by a rubber seal and secured with a sealant.

The closing member 1 of this valve is made of brass as well as the valve body 5.

Example 2

FIG. 4 and in particular from FIG. 5 of the drawing, it is clear that the two-way valve has a barrel-shaped closing member 1 equipped with channels 2 and seated in a cold-formed teflon seal 3 and that the closing member 1 is connected to the control handle 4. the valve body 5 as well as the outlet intermediate 6, which is screwed in the valve body 5 and oriented in the same direction as the valve body 5. This corresponds to the channel 2 in the closure member 1, which is likewise shown in FIG. 6. The outlet intermediate member 6 is sealed in the valve body 5 with a rubber seal and secured with sealant. The closure member 1 is secured in the valve body 5 by a nut 7 in which it is sealed with O-rings and this nut 7 is sealed in the valve body 5 by a rubber seal and secured with a sealant.

The closing member 1 of this valve is made of stainless steel as well as the valve body 5.

Advantageous properties of both the three-way and two-way valves according to the invention are based on the solution of the closure member 1 and at the same time on the properties of the annular Teflon seals 3. These are straight Teflon rings which are cold-formed into the radius of the closure. reliable valve tightness.
