Novel anti-corrosion ship steel casting piece stop valve

Abstract

The invention discloses a novel anti-corrosion ship steel casting piece stop valve and relates to the technical field of ship supporting equipment. The novel anti-corrosion ship steel casting piece stop valve comprises a valve body, a valve body inlet and valve body outlets, wherein the valve body inlet and the valve body outlets are arranged on the two sides of the valve body, the number of the valve body outlets is two to three, each valve body outlet comprises a straight pipe and a cone-shaped pipe, the straight pipe is fixedly connected with the valve body, the cone-shaped pipe is fixedly connected with the straight pipe, the straight pipe is provided with a section of external thread, the thread on the straight pipe is connected to a linear type sleeve, the sleeve is connected to a cone-shaped locking pipe, the locking pipe and the cone-shaped pipe have the same slant angles, in addition, the smallest diameter of the locking pipe is smaller than the largest diameter of the cone-shaped pipe, and the valve body inlet and the straight pipe are provided with a large ball valve and small ball valves respectively. The novel anti-corrosion ship steel casting piece stop valve has the advantages that the lock sealing of a fuel hose is achieved, the security coefficient is high, the stability is high, the operation is convenient, oil leakage can not occur, the large ball valve and the small ball valves are arranged on the valve body inlet and the straight pipe, the safety of the valve body is improved, and the probability of oil leakage is lowered.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for ships, in particular to a new corrosion-resistant marine steel casting cut-off valve body. Background technique: [0002] Currently on the market, the valve body of the existing fuel shut-off valve used in conjunction with the steel pipe fuel pipeline is mainly integrated by casting. The valve body of this fuel shut-off valve includes a valve body and a valve body port. The valve body port includes The valve body air inlet and the valve body air outlet. Among them, a ball valve is installed inside the valve body to control the cut-off of fuel oil. The advantage is that the production process is relatively simple and the price is relatively low compared with steel or copper materials. The strength is low, and excessive force may easily cause damage to the valve body. In the prior art, when the valve body is connected to the fuel hose, it is often necessary to fasten the fuel hose a...

In the prior art, when the valve body is connected to the fuel hose, it is often necessary to fasten the fuel hose and the valve body outlet with an iron wire to avoid leakage. Oil, very inconvenient, and generally use a ball valve, poor safety
