Abstract

The invention relates to a one-way valve, in particular to a pipeline valve. The one-way valve comprises a handle, a valve stem, an adjusting nut, a valve stem seal ring, a spool, an entry valve block, a spool seal ring and an exit valve block. The entry valve block is connected with the exit valve block in a threaded manner. The spool seal ring and the spool are enclosed in the entry and exit valve blocks. The spool is connected with the valve stem which is provided with the handle. The valve stem seal ring is disposed between the valve stem and the exit valve block and fixed through the adjusting nut. The one-way valve is characterized in that the spool is an entry valve block spool fitted in the exit valve block and connected with the valve stem; the spool is a one-way spool; the middle of the spool is provided with a through hole; an inner wedged rubber ring is disposed inside the through hole; a ball is disposed inside the inner wedged rubber ring. The one-way valve has the advantages of novel structure, simplicity in manufacture, convenience of use, wide range of application, safety and reliability and the like; therefore, the novel one-way valve is both economical and practicable.

Description

technical field [0001] The one-way valve of the present invention relates to a pipeline valve. Background technique [0002] At present, there are many valves sold on the market, including one-way valves, but the current one-way valves are very complicated in structure, complex in production process and high in cost. In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of one-way valve so as to overcome the existing problems in the prior art. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to research and design a new type of one-way valve. It is used to solve the problems existing in the prior art: complex structure, complex production process and high cost. [0004] The technical solution of the present invention is realized as follows: [0005] The one-way valve of the present invention is composed of a handle, a val...
