The invention relates to the technical field of valves, and in particular relates to a novel pipeline valve; the novel pipeline valve is characterized by comprising a water inlet device, a valve rod, a valve body, a water inlet, a flashboard water inlet, a point seat core, a transfer port, a pollution discharge water outlet and a cooling seal grove; according to the novel pipeline valve, the pollution discharge water outlet is arranged at the bottom of the flashboard to lead the water in the cooling seal groove out so that the temperatures of the valve rod and the valve body of the pipeline valve are reduced and the sealing is ensured.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a novel pipeline valve. Background technique [0002] In order to prevent pipeline leakage, traditional pipeline valves use rubber soft seals that are prone to failure, causing the valve to fail easily. When the seal fails, it is easy to cause gas leakage and affect public safety. Contents of the invention [0003] In order to solve the above-mentioned deficiencies, a new pipeline valve with good sealing performance, high temperature resistance, high pressure resistance, corrosion resistance and long life is provided. The new pipeline valve is characterized in that it includes: water inlet device 1, Valve stem 2, valve body 3, water inlet 4, gate water inlet 5, point seat core 6, transfer port 7, sewage outlet 8, cooling sealing groove 9, the new type of pipeline valve, around the valve body A cooling sealing groove 9 is provided, and a sewage discharge outlet 8 is set at the ...
