Abstract

The utility model belongs to an improvement on an angular stop valve. A plunger structure is led into an angular valve body, and a bracket is additionally arranged between an upper sealing ring and a lower sealing ring. A valve cover is supported against the upper sealing ring. The regulation of a screw bolt and a screw nut on the valve cover is used to achieve effective sealing between the plunger and the sealing ring and between the sealing ring and the inner wall of the valve body. At the same time, PIFE material is adopted to make the sealing ring, so as to improve the temperature resistance of the valve body. The utility model has the advantages of simple structure, long service life, reliable closing, convenient replacement, etc.

Description

The angie type plunger valve

The utility model belongs to a kind of improvement of Angle Stop valves.

Existing Angle Stop valves often in use for some time, can occur run emit, water clock and close phenomenons such as not tight, its reason is to be hard sealing between spool and valve body, seal not tight, the long-time use, can be because of wearing and tearing produce the gap, and can not be in time regulate from itself structure, thereby influenced sealability and the working life of angie type by column valve.

The purpose of the utility model is to provide a kind of long service life, seals the angie type plunger valve that can regulate.

The technical solution of the utility model is such: it is by having orthogonal inlet/outlet passage and the valve body that holds the open-shut device valve pocket, cover the valve gap on valve body, be contained in the upper-lower seal ring in the valve pocket, the valve rod that supports support, plunger and the drive plunger lifting of upper-lower seal ring, handwheel composition successively.Plunger is being done upper and lower keying lifting in the upper-lower seal ring under the driving of external force; Wherein roof pressure is on upper sealing ring in the middle of the valve gap, and the seal degree between valve body and seal ring, plunger and the seal ring is regulated by bolt, nut.

In order to improve working life of the present utility model, increase Applicable scope, the upper-lower seal ring adopts the PIFE material, and promptly teflon and graphite mix, and plunger adopts stainless steel material.

Because the working surface of plunger and upper-lower seal ring is not subjected to the influence of extraneous factor, and tightness degree therebetween can regulate by nut, so seal degree of the present utility model is good, and long service life.

Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.

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

Angie type plunger valve described in the utility model is by valve body 10, be fixed on valve gap 8 on the valve body 10 with bolt 4, nut 3, place the valve rod that upper-lower seal ring 6, support 9, plunger 5 and an end are connected on the plunger 5, the other end is being fixed handwheel 12 on valve body 10 valve pockets to form.

Valve body 10 has and orthogonally flows to passage 11, outflow opening passage 7 and hold the valve pocket that opens and closes valve member, and support 9 supports upper and lower seal ring 6, makes it can keep relatively-stationary distance.Plunger 5 adopts stainless steel material to make the garden cylindrical plug in upper-lower seal ring 6, and can open or closed position intercropping elevating movement on valve pocket upper-lower seal ring 6 under the driving of handwheel 1.Upper and lower seal ring 6 adopts teflon and graphite to be mixed and made into, i.e. PIFE material, and it has resistant to elevated temperatures characteristic.

Valve gap 8 roof pressures are on upper sealing ring 6, seal degree between plunger 5 and seal ring 6, valve body 10 and the seal ring 6 is regulated by bolt 4, nut 3, during tightening nut 3 on compressing valve gap 8, upper-lower seal ring 6 can be done the appropriateness expansion diametrically, thereby it more is adjacent on plunger 5 sidewalls and valve pocket inwall, effectively seals so guaranteed seal ring 6.Valve gap 8 has certain adjusting play with valve body 10 junctions, when in the using process because of wearing and tearing cause when leaking, fastening stud 4, the nut 3 that can suitably adjust on the valve gap 8 are got rid of; If the seal ring 6 that need to change damages, only need unload bottom flange 8, plunger 5, support 9 and get final product, whole angle valve need not be pulled down.

Obviously, the utlity model has applied widelyly, close reliably, long service life, is changed advantages such as convenient at maintenance.

Claims

1, a kind of angie type plunger valve, comprise the valve body (10) that has mutually perpendicular inlet/outlet passage (11,7) and hold the open-shut device valve pocket, cover the valve gap (8) on valve body (10), with open valve rod (2), the handwheel (1) that valve member is connected, it is characterized in that: open-shut device is plunger (5), the outer support (9) that upper and lower seal ring (6) is housed and supports upper and lower seal ring (6) of plunger (5), described valve gap (8) roof pressure is on upper sealing ring (6).

2, according to the described angie type plunger valve of claim 1, it is characterized in that: fixedly connected with bolt (4), nut (3) between valve gap (8) and the valve body (10).
