Abstract
The utility model discloses a non-packing leakage-proof valve. The upper part of a leading screw is provided with a bearing. A spring is arranged between the bearing and an upper cover of the valve. The inner part of the upper cover of the valve is connected with a sealing guide sleeve barrel through a screw thread. The leading screw is positioned in the sealing guide sleeve barrel. The upper part of the leading screw at the lower part of the sealing guide sleeve barrel is provided with a sealing gasket and a sealing ring. The lower part of the leading screw is connected with a guide sleeve barrel of a valve head through a screw thread. The outer part of the sleeve barrel is connected with the valve head. The sealing structure of the valve leads the part between the sealing ring and the sealing guide sleeve barrel to have the function of a small stop valve, which can ensure a sealing effect.
Description
The utility model relates to a kind of valve, is the non-stuffing leakproof valve specifically.
Existing industrial valves has packing, uses Gland sealings such as asbestos rope, graphite, in use easily loosening, wearing and tearing, and the packing place is leaked, for opening frequent valve, the easier leakage accident that causes influences ordinary production.
The purpose of this utility model is to provide the non-stuffing leakproof valve, makes valve seal reliable, makes things convenient for the user.
The technical solution of the utility model is as follows:
This device has the inlet/outlet of valve body, leading screw, valve head, medium, a bearing is adorned on the top of leading screw, between the loam cake of bearing and valve, adorn a spring, the loam cake of valve is interior with the sealing pilot sleeve that is threaded, in the sealing pilot sleeve is leading screw, on the leading screw sealing gasket and seal ring are housed below the sealing pilot sleeve, the bottom of leading screw connects the valve head pilot sleeve with screw thread, and this sleeve connects valve head outward.
Advantage of the present utility model is: 1, the top of valve adds spring, makes the effect that small-sized stop valve is arranged between seal ring and sealing pilot sleeve, guarantees sealing effect.2, good seal performance reduces maintenance and makes things convenient for the user.3, simple in structure, make easily.
Fig. 1 is the utility model sectional structure chart;
The utility model is described in further detail below in conjunction with accompanying drawing.
Can see leakproof valve of the present utility model by Fig. 1, it has valve body (6), leading screw (1), valve head (13), advancing of medium, outlet (7), (8), a bearing (2) is adorned on the top of leading screw, between the loam cake (5) of bearing and valve, adorn a spring (3), the loam cake of valve is fixing by tightening nut (4), the loam cake of valve (5) is interior with the sealing pilot sleeve (9) that is threaded, in the sealing pilot sleeve is leading screw (1), below the sealing pilot sleeve, on the leading screw sealing gasket (10) and seal ring (11) are housed, the bottom of leading screw connects valve head guide sleeve letter (12) with screw thread, connect valve head (13) outside this cover letter, located seal ring (14) at valve head and medium import (7).
The outer wire drawing thick stick of spring (3) (1), because of the leading screw rotation, not upper and lower moving compresses the interior sealing pilot sleeve (9) of the leading screw seal ring (11) and the loam cake of valve, plays the effect of stop valve, prevents to leak.
Claims (1)
1, a kind of non-stuffing leakproof valve.It has valve body (6), leading screw (1), valve head (13), the inlet/outlet (7) of medium, (8), it is characterized in that: a bearing (2) is adorned on the top of leading screw, between the loam cake (5) of bearing and valve, adorn a spring (3), the loam cake of valve (5) is interior with the sealing pilot sleeve (9) that is threaded, in the sealing pilot sleeve is leading screw, below the sealing pilot sleeve, on the leading screw sealing gasket (10) and seal ring (11) are housed, the bottom of leading screw connects valve head pilot sleeve (12) with screw thread, and this sleeve connects valve head (13) outward.
