Abstract
The invention discloses a manual waterproof valve, which comprises a valve body, and a valve rod of which one end is arranged in the valve body, wherein the upper end of the valve rod is sleeved with a lining; a rubber ring is arranged between the valve rod and the lining; a horizontal retaining ring is fixedly arranged above the lining; a spring is connected between the horizontal retaining ring and the lining; the outer side wall of the valve body is provided with a circular tightening ring; a seal ring is arranged in the circular tightening ring; and the bottom end of the valve rod is provided with a key ring. The waterproof valve has a compact structure, and has smaller volume and longer service life than the conventional waterproof valve; during installation, the waterproof valve can be directly connected with a pipeline, and is firm in structure and easy to install; and a seal gasket is arranged at a matching position of the valve rod and the inner wall of the valve body of the waterproof valve, so that the sealing performance of the waterproof valve is high.
Description
Technical field
The present invention relates to a kind of manual waterproof valve, belong to valve technology field.
Background technique
Existing waterproof valve generally is to be formed than combine and assemble such as thin nuts by the hexagonal that the pad of the fastening spring of valve body, coupling shaft, fixed connection shaft and valve body, the fastening spring of sealing, when installing and water pipe connecting part get gasket seal, fit sealing packing ring; This traditional processing cost is high, unreasonable structure; In use; This waterproof valve damages easily, brings a lot of inconvenience for actual the use.
Summary of the invention
For deficiency and the defective of alleviating existing technology; The object of the present invention is to provide a kind of manual waterproof valve, the tightly short existing waterproof valve volume of waterproof valve structure of the present invention is lighter, longer service life; Can directly be connected when mounted with pipeline; Sound construction, install simply, the valve rod of waterproof valve and valve interior wall matching part are provided with gasket seal, make the good seal performance of waterproof valve.
The present invention adopts following technological scheme to achieve these goals:
Manually waterproof valve comprise valve body, and an end is installed on the valve rod of valve inner; It is characterized in that: the outer lining that is with in described valve rod upper end; Be provided with rubber ring between described valve rod and the lining, described lining upper fixed is equipped with horizontal back-up ring, is connected with spring between described horizontal back-up ring and the lining; Described valve body outer side wall has circle and tightens up circle, and described circle tightens up and lays circular seal ring in the circle.
Described manual waterproof valve is characterized in that: described valve rod bottom is equipped with key ring.
Advantage of the present invention:
The tightly short existing waterproof valve volume of waterproof valve structure of the present invention is lighter; Longer service life can directly be connected with pipeline when mounted, and sound construction, installation are simply; The valve rod of waterproof valve and valve interior wall matching part are provided with gasket seal, make the good seal performance of waterproof valve.
