Abstract
The utility model discloses a kind of wedge-type and compensate ball valve, belong to ball valve field.This wedge-type compensates ball valve and comprises valve body, lower valve rod, spheroid and valve gap, is provided with wedge shape valve seat between valve gap and spheroid.The utility model is intended to, for after the soft prooving of valve seat, to compensate fast, make it again reach seal request to wear surface.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of wedge-type and compensates ball valve.
Technical background
Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Be provided with spheroid in ball valve, have manhole or passage by its axis, be mainly used in pipeline make the flow direction cutting off, distribute and change medium, only need tightly or all to open with spheroid 90-degree rotation and very little moment of rotation just can be closed.But unavoidably can to the prooving of valve seat sealed in the opening-closing process of spheroid, after the prooving of valve seat, the sealability of ball valve reduces greatly, opens and closes and also more requires great effort.The valve seat more renewed not only complicated operation, also needs prolonged shutdowns, time-consumingly takes a lot of work, and the economic loss caused is also large.
Model utility content
The utility model discloses a kind of wedge-type and compensate ball valve, be intended to, for after the soft prooving of valve seat, to compensate fast wear surface, make it again reach seal request.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Wedge-type compensates ball valve, and comprise valve body 3, lower valve rod 6, spheroid 4 and valve gap 1, it is characterized in that: be provided with wedge shape valve seat 2 between valve gap and spheroid, the end face that valve gap 1 contacts with wedge shape valve seat 2 is wedge shape, and adaptive with the wedge-type shape of wedge shape valve seat 2.
Be provided with adjusting screw 5 in described lower valve rod 6, spheroid 4 is withstood in its one end.
The beneficial effects of the utility model are:
One, the utility model is for solving quick compensation problem, only improves for valve seat and valve gap, and its structure is simple, and cost is low, easily realizes, and is beneficial to popularization;
Two, the utility model processing ease, wear and tear to some extent at valve seat, seal failure occurs, when generation is slightly revealed, only need unclamp the adjusting screw in lower valve rod, spheroid and the downward landing of valve seat, because the wedge-shaped structure of valve seat coordinates, more past whereabouts, then valve seat is more adjacent to from trend spheroid, compensate for wear part, after again reaching seal request, holds out against adjusting screw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 be valve gap, 2 be wedge shape valve seat, 3 be valve body, 4 be spheroid, 5 be adjusting screw, 6 for lower valve rod.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1, wedge-type compensates ball valve, and comprise valve body 3, lower valve rod 6, spheroid 4 and valve gap 1, it is characterized in that: be provided with wedge shape valve seat 2 between valve gap and spheroid, the end face that valve gap 1 contacts with wedge shape valve seat 2 is wedge shape, and adaptive with the wedge-type shape of wedge shape valve seat 2.Be provided with adjusting screw 5 in described lower valve rod 6, spheroid 4 is withstood in its one end.After valve seat soft seal weares and teares, sealing may be lost efficacy, and produced and slightly revealed.Now troublesome ball valve of taking apart changes valve seat, and not only waste, and the time spent is many, cost of labor is high.Adopt the utility model, the adjusting screw 5 only need come up in lower valve rod 6, now spheroid 3 down landing together with wedge shape valve seat 2, because the matching relationship of wedge shape valve seat 2, more down landing, then fit tightr and tightr between wedge shape valve seat 2 and spheroid 3, sealing compensation has been carried out to abrading section, make its sealability again reach requirement.After the utility model solves the soft prooving of valve seat, can compensate fast wear surface, make it again reach seal request.Only improve for valve seat and valve gap, structure is simple, low, the easy realization of processing ease, cost, be beneficial to popularization
Claims (2)
1. a wedge-type compensates ball valve, comprise valve body (3), lower valve rod (6), spheroid (4) and valve gap (1), it is characterized in that: between valve gap and spheroid, be provided with wedge shape valve seat (2), the end face that valve gap (1) contacts with wedge shape valve seat (2) is wedge shape, and adaptive with the wedge-type shape of wedge shape valve seat (2).
2. wedge-type according to claim 1 compensates ball valve, it is characterized in that: be provided with adjusting screw (5) in described lower valve rod (6), spheroid (4) is withstood in its one end.
