Abstract
The utility model discloses a special pressure reducing valve for oxygen, which comprises a valve body 1 and a valve cover 6, the bottom portion of the valve body 1 is equipped with a valve bottom cover 2, the upper portion of the valve bottom cover 2 is connected with a spring 3, the spring 3 is connected with a valve clack component 4, the upper portion of the valve body 1 is equipped with a piston 7, the lower end of the piston 7 is pushed against the valve clack component 4, the upper end of the valve cover 6 is connected with a pilot valve 5, the pilot valve 5 is connected with an inlet pressure gauge 10 and an outlet pressure gauge 11, two sides of the pilot valve 5 are connected with pressure leading pipes 8, the pressure leading pipes 8 on the two sides are communicated with flanges at the two ends of the valve body 1. The utility model has the advantages that the pressure reducing valve is stable in pressure of the outlet of the pressure reducing valve and fine in safety, and is easy to control.
Description
Technical field
The utility model relates to a kind of decompressor, the special-purpose reduction valve of particularly a kind of oxygen.
Background technique
Oxygen reduction valve in the existing market is not provided with special-purpose reduction valve and flap assembly, causes the outlet pressure instability of reduction valve, and is wayward, poor safety performance.
The model utility content
At the shortcoming of existing oxygen reduction valve, the utility model provides a kind of novel oxygen reduction valve.
For the shortcoming that realizes avoiding above-mentioned oxygen reduction valve to be occurred, the measure that the utility model is taked is: the special-purpose reduction valve of a kind of oxygen, comprise valve body 1 and valve gap 6, valve bottom 2 is arranged at the bottom of described valve body 1, the top of valve bottom 2 is connected with spring 3, spring 3 is connected with flap assembly 4, the top of valve body 1 is provided with piston 7, the lower end of piston 7 withstands on the flap assembly 4, the upper end of valve gap 6 is connected with pilot valve 5, be connected with inlet pressure gauge 10 and delivery gauge 11 on the pilot valve 5, the both sides of described pilot valve 5 are connected with pressure inlet tube 8, and the pressure inlet tube 8 of both sides communicates with two end flange of valve body 1;
Be provided with the O RunddichtringO between described piston 7 and the valve body 1;
Described reduction valve material is a copper.
The beneficial effects of the utility model: the outlet pressure of reduction valve is stable, and easy to control, Safety performance is good.

Embodiment
See also its mode of execution of description of drawings:
The special-purpose reduction valve of oxygen is the control of reducing pressure of the pressure to medium, the special-purpose reduction valve of this oxygen, comprise valve body 1 and valve gap 6, valve bottom 2 is arranged at the bottom of described valve body 1, the top of valve bottom 2 is connected with spring 3, spring 3 is connected with flap assembly 4, the top of valve body 1 is provided with piston 7, the lower end of piston 7 withstands on the flap assembly 4, the upper end of valve gap 6 is connected with pilot valve 5, be connected with inlet pressure gauge 10 and delivery gauge 11 on the pilot valve 5, the both sides of described pilot valve 5 are connected with pressure inlet tube 8, and the pressure inlet tube 8 of both sides communicates with two end flange of valve body 1.The import of pilot valve is introduced by the inlet of impulse assembly from valve body, the feedback pressure of pilot valve is introduced by valve outlet port by the impulse assembly, through relatively behind the inlet and outlet pressure pressure being imported into the open degree that makes the piston longitudinal movement reach adjusting flap assembly in the piston cavity, adjustable lever is regulated pilot valve and is reached the valve outlet port desired parameters.Be provided with the O RunddichtringO between described piston 7 and the valve body 1.
Medium entered pilot valve by pressure inlet tube when working principle was a medium by the special-purpose reduction valve of oxygen, regulate pilot valve piston is moved up and down, thereby the aperture of regulating the flap assembly makes the medium decompression of passing through; The pressure that the outlet pressure inlet tube is introduced obtains own balance by pilot valve and finally reaches the required weighing apparatus definite value of operating mode.Products characteristics: 1. the special-purpose reduction valve of oxygen is to carry out can regulate control by pilot valve, and outlet pressure carries out balance, finally reaches a stable outlet pressure parameter.2. valve body is provided with the flap assembly, and flap assembly below is provided with spring, and flap assembly upper fixed connects and piston.3. this product is imported and exported and is provided with the impulse pipe fitting, and inlet and outlet pressure is introduced to pilot valve and compares, and the adjusting pilot valve makes the pilot valve inner spring compress or loosen the balance inlet and outlet pressure that the outlet pressure of medium has been controlled in the upper and lower displacement of piston.4. piston is provided with O type circle and is used for piston seal.5. these product import and export are to adopt flange to connect.Adopted full Cu alloy material in design, accidents happened to prevent oxygen.
