Abstract

The utility model relates to a valve, in particular to a fluoroplastic fully lining ball valve which is applied to industries, such as petroleum, chemical industry, pesticides, medicaments and the like, and a pipeline of which the medium is corrosive fluid, such as strong acid, strong alkali and the like, and serves as an opening and closing device. The fluoroplastic fully lining ball valve comprises a valve body, a valve cap, a handle, a filler gland, a filler box, a ball body and a valve rod, wherein the valve cap and the valve body are connected through a bolt; sealing rings are arranged in the valve cap and the valve body; sealing components are arranged between the valve rod and the filler box, and between the valve rod and the filler gland; a non-circular groove is formed on the upper part of the ball body; the cross section of the lower end of the valve rod is matched with the groove; and the lower end of the valve rod is inserted into the groove of the ball body. The fluoroplastic fully lining ball valve has a long service life, low replacing cost and high sealing property.

Description

A kind of fluoroplastic all-liner ball valve

Technical field

The utility model relates to a kind of valve, is specifically related to a kind of industries such as oil, chemical industry, agricultural chemicals, medicine that are used for, and medium is on the pipeline of strong acid, highly basic class corrosive fluid, as the fluoroplastic all-liner ball valve that opens and closes device.

Background technique

At present, the valve that China's chemical industry is used for deep-etching flowing medium controls such as strong acid, highly basic mostly is ordinary ball valve greatly, valve rod is fixedlyed connected with spheroid, need integral replacing during damage, cause monomer working life short, replacement cost is high, causes very serious economy loss and inevitably potential safety hazard; And Sealing is for serving as a contrast or be lined with common material entirely, and lining is pasted not strongly and causes the Sealing damage that easily comes off admittedly, easily leaks, even security incident takes place.

Summary of the invention

The purpose of this utility model is to provide that a kind of long service life, replacement cost are low, the fluoroplastic all-liner ball valve of good seal performance.

The purpose of this utility model is achieved in that a kind of fluoroplastic all-liner ball valve, comprise valve body, valve gap, handle, Gland, Stuffing box, spheroid, valve rod, valve gap is connected by bolt with valve body, in valve gap and the valve body seal ring is set, between valve rod and Stuffing box and the Gland Sealing is set, described spheroid top is provided with non-circular slot, the following end section of described valve rod and described groove fit, and the valve rod lower end is plugged in the groove of spheroid.

As a kind of improvement of the present utility model, described valve body, valve gap, spheroid, valve rod, Stuffing box all are lined with fluoroplastics layer.

The utility model becomes split type with valve rod with ball design, and transmitting torque power is big, intensity is high, be convenient to repair and replacement and replacement cost is low, has also prolonged working life owing to change conveniently; Valve body, valve gap, spheroid, valve rod, Stuffing box all are lined with fluoroplastics layer, has superior corrosion resistance, almost can resist all chemical mediators, can use for a long time below the temperature at 180 ℃, also have excellent lubrication, electrical insulating property, creep resistance and non-viscosity, can satisfy the requirement of special operation condition.

In sum, the utility model long service life, low, the good seal performance of replacement cost.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of fluoroplastic all-liner ball valve, comprise valve body 8, valve gap 1, handle 9, Gland 2, Stuffing box 6, spheroid 3, valve rod 4, valve gap 1 and valve body 8 are connected by bolt, in valve gap 1 and the valve body 8 seal ring 7 is set, between valve rod 4 and Stuffing box 6 and the Gland 2 Sealing 5 is set, spheroid 3 tops are provided with non-circular slot 10, the following end section of valve rod 4 cooperates with groove 10, and valve rod 4 lower ends are plugged in the groove 10 of spheroid 3.

Valve gap 1 internal surface is lined with valve gap fluoroplastics layer 101, spheroid 3 surfaces are lined with spheroid fluoroplastics layer 301, the surface of valve rod 4 is lined with valve rod fluoroplastics layer 401, the internal surface of Stuffing box 6 is lined with Stuffing box fluoroplastics layer 601, the internal surface of valve body 8 is lined with valve body fluoroplastics layer 801, spheroid 3 lower ends are equipped with through hole, and spheroid fluoroplastics layer 301 infiltrates and makes spheroid fluoroplastics layer 301 form whole difficult drop-off in the through hole.
