Embodiment

[0019] Example: see Figures 1 to 5 As shown, a cut-off valve applied to a silicone pipeline includes a valve seat 1, a valve sleeve 2 and a valve core 3. A cavity 21 is formed on the valve sleeve 2, and a discharge hole 22 is formed on the bottom surface of the cavity 21. The valve The sleeve 2 is screwed on the valve seat 1, and the valve seat 1 is formed with a feed hole 11, and the two ends of the valve core 3 are respectively inserted into the discharge hole 22 of the valve sleeve 2 and the feed hole 11 of the valve seat 1, A ring groove 12 is formed on the inner wall of the feed hole 11 of the valve seat 1, and an elastic sleeve 6 is inserted and fixed in the ring groove 12. The lower end of the valve core 3 is inserted into the elastic sleeve 6, and a penetrating valve core 3 The channel 31 on the top surface, the inner wall of the bottom end of the channel 31 is formed with a through hole 32 penetrating through the outer wall of the valve core 3, the inner wall of the ...

Abstract

Disclosed is a stop valve applied to a silica gel pipeline. The stop valve comprises a valve seat, a valve sleeve and a valve element; an annular groove is formed in the inner wall of a feeding hole of the valve seat; an elastic sleeve is fixedly inserted into the annular groove; the lower end of the valve element is inserted into the elastic sleeve; a channel which penetrates through the top end face of the valve element is formed in the valve element; a through hole which penetrates through the outer wall of the valve element is formed in the inner wall of the bottom end of the channel; a cut groove is formed in the inner wall of the elastic sleeve and communicated with the feeding hole of the lower side of the valve element; a partition board is formed on the bottom surface of a cavity groove of the valve sleeve; one vertical side of the partition board is formed on the inner wall of the cavity groove and the other side of the partition board abuts against the outer wall of the valve element; a side board is formed on the outer wall of the valve element and located in the cavity groove of the valve sleeve; an outer vertical side of the side board abuts against the inner wall of the cavity groove of the valve sleeve; an air inlet hole and an air outlet hole which are communicated with the cavity groove are formed in the positions, on the two sides of the partition board, of the outer wall of the valve sleeve respectively. The stop valve applied to the silica gel pipeline is simple in structure, an existing stop valve on an injection molding machine is simplified, the production cost is reduced, and the influence of sizing material flow and pressure is small.

Description

Technical field: [0001] The invention relates to the technical field of valve bodies, in particular to a shut-off valve applied to silicone pipelines. Background technique: [0002] The valve body is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Shut-off valve is the most widely used type of valve body, which is used to control the circulation or cut-off of fluid. Shut-off valves are generally used on silicone pipes of injection molding machines to control the flow or cut-off of rubber materials. However, the shut-off valve on the silica gel pipeline in the prior art has the defects of complex structure, high manufacturing cost, and great influence by flow rate and pressure. Invention content: [0003] The object of the present invention is to provide a shut-off valve applied to silicone pipelines, which has the ...
