Abstract

The utility model discloses a flush resistant stop valve, belonging to piping valve. A bracket and an upper cover are positioned on the upper of the valve body, and a plane bearing and a copper nut are positioned in the upper cover. The valve base is pressed on the valve body by a throttle sleeve, a graphite gasket, a filler pressing seat and a filler pressing cover, and can be disassembled, the seal surface is welded on the valve seat in stack rather than the valve body, driven by an electric device or a hand wheel, a valve-core valve-stem component reciprocates up and down in the throttle sleeve though the copper nut and the bearing. A hole is arranged on the throttle sleeve, when the valve core is opened and closed, with the change of the opened hole on the throttle sleeve, the throttle sleeve bears partial pressure, thereby the scour to the valve seat seal surface is reduced and the flow rate is adjusted.

Description

The anti-stop valve that washes away
Technical field
The utility model belongs to pipeline valve, particularly a kind of anti-stop valve that washes away in order to media flow in the controlling plumbing fixtures.
Background technique
At present, the employed stop valves of industry such as petrochemical industry, light textile, metallurgy, electric power, chemical industry, its main member is valve body and spool valve rod assembly, the direct built-up welding of sealing surface is on valve body, and when the little aperture opening and closing of valve, the pressure reduction on the valve nearly all concentrates on the sealing surface, thereby it is very serious to washing away of the sealing surface of spool and valve body, damage easily, and the switch of valve only relies on the screw thread on the valve rod directly to pump, needed thrust is bigger.Stop valve uses on the high temperature and high pressure steam pipeline in addition, and during valve closing, the medium temperature difference is very big before and after the sealing surface, and after use a period of time, crackle often appears in the sealing surface of valve body pile-up welding hard alloy, has a strong impact on the normal operation of pipeline.Because sealing surface is welded on the valve body, valve body must be cut off from pipeline during maintenance, pile-up welding hard alloy is welded to behind the processing grinding on the pipeline more again, has brought a lot of inconvenience to maintenance, and has increased production consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-stop valve that washes away at the deficiencies in the prior art.It is characterized in that: the anti-stop valve that washes away is made up of valve body 1, valve gap 2, spool valve rod assembly 3, valve seat 4, work in copper spirit 5, loam cake 6, bearing 7 and throttle sleeve 8.
Described valve body 1 external form is a cuboid, and interface and the adapter with pipeline welding left in both sides, and valve body 1 top is support 9 and loam cake 6, and bearing 7 and work in copper spirit 5 are arranged in the loam cake 6.
Described valve seat 4 relies on throttle sleeve 8, graphite pads 10, filler wedge 11 and Gland 12 to be pressed on the valve body 1, and detachable, and sealing surface weld deposit is on valve seat 4, and the rotatingshaft or the manual pulley of spool valve rod assembly 3 and Electric actuator are connected; Have fenestra on the throttle sleeve 8.
Described sealing surface is the conical surface.
Described work in copper spirit 5 is made by aluminum bronze.
Described valve gap 2 adopts forged steel pieces to weld together with valve body 1, or for directly making integral body.
Described Electric actuator or manual pulley can side direction be installed.
The beneficial effects of the utility model are that the anti-stop valve that washes away has increased valve seat, throttle sleeve, work in copper spirit, loam cake and five parts of bearing, compared with prior art has following advantage:
The first, because valve seat is not an integral body with valve body,, avoided the generation of sealing surface crack performance so there is the clearance for expansion;
The second, valve seat is not an integral body with valve body, has made things convenient for the user to dismantle in maintenance and changes spare part, thereby prolonged the whole service life of valve, has shortened user's repair cycle simultaneously yet;
The 3rd, throttle sleeve can play throttling and regulatory function, thereby satisfies the various situations in using;
The 4th, rely on the drive of bearing and work in copper spirit, friction reduces, and needed thrust also reduces, and operates more flexible.

Embodiment
The utility model is a kind of anti-stop valve that washes away, and is made up of valve body 1, valve gap 2, spool valve rod assembly 3, valve seat 4, work in copper spirit 5, loam cake 6, bearing 7 and throttle sleeve 8.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, described valve body 1 external form is a cuboid, and interface and the adapter with pipeline welding left in both sides, and valve body 1 top is support 9 and loam cake 6, and bearing 7 and work in copper spirit 5 are arranged in the loam cake 6.
Described valve seat 4 relies on throttle sleeve 8, graphite pads 10, filler wedge 11 and Gland 12 to be pressed on the valve body 1, and it is detachable, sealing surface weld deposit is on valve seat 4, the rotatingshaft or the manual pulley of spool valve rod assembly 3 and Electric actuator are connected, and pump in throttle sleeve 8 by work in copper spirit 5 and bearing 7.Have fenestra on the throttle sleeve 8, when the spool opening and closing, along with fenestra on the throttle sleeve 8 is opened the change of size, born partial pressure on the throttle sleeve 8, reduced the washing away of sealing surface of seat, simultaneously, convection current has measured regulating action.
Described sealing surface is the conical surface.
Described work in copper spirit 5 is made by aluminum bronze.
Described valve gap 2 adopts forged steel pieces to weld together with valve body 1, or for directly making integral body.
Described Electric actuator or manual pulley can side direction be installed.
