Problems solved by technology

[0002] Valves are widely used in refrigeration, refrigeration, air conditioning, heat pump, chemical industry, petroleum and other industries. At present, most of the valves used for general-purpose refrigerants and non-corrosive gas and liquid control adopt traditional structure valves. Commonly used valves such as globe valves , Regulating stop valve, check valve, stop check valve, ball valve, butterfly valve, etc., due to their structure, there is a sliding sealing point between the valve stem and the valve body, it is difficult to solve the sealing problem of the refrigerant, small and medium specifications The valve seat of the valve is generally made of forged steel structure, and the valve seat of the larger size valve is generally imported. The current medium and low pressure pipeline valves are all cast iron structure, and the pipeline is connected with flanges and bolts, and gaskets are used. Sealing, this kind of cast iron valve is relatively large in size and weight, and it is easy to leak when it is connected by flange bolts.

Embodiment Construction

[0012] Such as figure 1 , 2 The steel refrigeration valve shown has a valve body 1, a valve cover 8, a valve stem 4, a valve disc 5, and a valve stem sleeve 6. The valve body 1 is fixedly connected with an inlet pipe 2 and an outlet pipe 3, and the valve disc 5 Set at the front of the valve stem 4, the valve stem sleeve 6 is sleeved outside the valve stem 4, and is welded and connected to the valve cover 8 as a whole. The valve stem 4 and the valve stem sleeve 6 are threadedly connected. The valve body 1 is a steel pipe, and the inlet pipe 2 The tube is stretched and welded to the inlet tube 2. The inlet tube 2 extends into the valve body 1 to form a valve surface corresponding to the valve disc 5. The valve body 1 is welded to the outlet tube 3 at the outlet tube 3, and the valve cover 8 is arranged above the valve body 1, and is fixedly connected with the valve body 1 by bolts 7. A sealing cover 9 is arranged between the valve stem 4 and the valve stem sleeve 6, the sealing cov...

Abstract

The valve is composed of the valve body, valve cap, valve shaft, valve petal and valve rod cover. The inlet and outlet pipes are fixed on the valve body. The valve petal is set at the front end of the shaft. The valve rod covers on the shaft and is welded with the valve cap. The shaft is spiral connected with the valve rod cover. The valve body is a steel pipe welded with the outlet pipe. The cap is on the top of the valve body and fixed through the bolt.

Description

Technical field [0001] The invention relates to a valve, in particular to a steel that is suitable for the control of all common refrigerants and non-corrosive gases and liquids, and is used in various pipeline systems to cut off or connect to control fluid pressure, flow and flow direction. The system valve. Background technique [0002] Valves are widely used in refrigeration, refrigeration, air conditioning, heat pumps, chemical, petroleum and other industries. At present, most of the valves used for general-purpose refrigerants and non-corrosive gas and liquid control use traditional valves. Commonly used valves such as globe valves , Regulating cut-off valve, check valve, cut-off check valve, as well as ball valve, butterfly valve, etc. Due to their structure, there is a sliding sealing point between the valve stem and the valve body, which is difficult to solve the refrigerant sealing problem, small and medium specifications The valve seat of the valve is generally of forge...
