Thus, the control rod can directly combine with a grab handle or the actuator which can be operated automatically.

Description

Ball valve connector able to switch automatic control to manual control

The utility model relates to a kind of convertible ball valve connecting base of operation automatically that manually reaches.

The design of general ball valve, as Fig. 4 to shown in Figure 6, be with a lever A structure of holding on controlling rod B, controlling rod B extends down among the ball valve body C, when lever A rotated with handling, drive controlling bar B rotated, to adjust opening and closing of ball valve.Be sealing state for making between controlling rod B and the ball valve body C, so establish a sealing cover D between controlling rod B and ball valve body C.When this manual ball valve desires to be transformed into electronic or pneumatic operation, with the pneumatic operation is example, as Fig. 5 and shown in Figure 6, at first should blind off a line, pull down lever A, sealing cover D then respectively, reconfigure leakproof seal lid then, adorn separately again on a vavle shelf E, the vavle shelf E again in conjunction with pneumatic actuator F, simultaneously, curtailment (installing the event of vavle shelf E additional) because of controlling rod B, so must between controlling rod B and pneumatic actuator F, install a connection piece G additional, just can make pneumatic actuator F drive controlling bar B.Can obviously find out by above explanation, when the conventional ball valve desire when manually-operable is transformed into automatic operation, must blind off a line earlier, prepare multiple member then.Simultaneously, the default hole of the apical margin of ball valve body C (Top flange) needs the combination of tapping for vavle shelf E, and therefore, spare part increases, and it is all very loaded down with trivial details to tear group open, even needs the technician could operation, and cost increases thereupon.Moreover, owing to must install a vavle shelf E additional, thereby increased its shared space, for the place of the restriction of having living space, promptly cause the puzzlement of installing.

The purpose of this utility model is to provide a kind of convertible manually and automatically ball valve connecting base of operation, and is easy and simple to handle when making ball valve desire to be transformed into automatic operation by manually-operable, do not increase additional member, saving space and reduces cost.

According to a kind of convertible manually and automatically ball valve connecting base of operation of the present utility model, this connecting base is incorporated on one of the ball valve body rim portion, and this ball valve body has the Control Shaft that passes this connecting base, it is characterized in that:

This connecting base has one and entreats axis hole for this Control Shaft among passing, these connecting base both sides stretch out respectively and form a pair of ear, each ear has a perforation that corresponds to the default joining hole of this rim portion respectively, to pass and in conjunction with the two for a screw rod respectively, and each ear both sides forms an alar part respectively, and each wing part is provided with the perforation for an automatic operate actuator combination;

In conjunction with a lever or be replaced by actuator, and be able to conversion mutually between a manual operator scheme and an automatic operation mode on this connecting base of mat.

So, when manually-operable, directly be incorporated on the controlling rod with lever, can use, when desiring to be transformed to automatic operation, only need pull down lever and directly actuator be made up on controlling rod, and the perforation of mat both wing portions is for the actuator combination; Otherwise,, refill lever and get final product if need only need to pull down actuator when being transformed to manually-operable automatically.So very easy during conversion, need not blind off a line, expend cost and also can reduce.

In brief, the utility model provides following advantage at least: (1) exchange operation automatic and manually-operable is very easy; (2) need not increase additional member; (3) need not increase vavle shelf, so it is few to take volume; (4) manufacturer and user's cost all obviously reduces; And do not need to blind off a line in (5) conversion operation.

Below lift a preferred embodiment and conjunction with figs. now, describe the structure characteristics and the technology contents of the utility model in detail.

Fig. 5 is the three-dimensional exploded view of ball valve shown in Figure 4; And

Stereogram when Fig. 6 is transformed to automatic operation mode for conventional ball valve in conjunction with a pneumatic actuator.

At first consult shown in Figure 1, approximate within the ball valve body 100 with conventional ball valve, so repeat no more.The ball valve body 100 of the utility model has an axis hole 110 and stretches out outside the ball valve body 100 for controlling rod 200, controls it for ball valve and opens or closes.A connecting seat 10 is located between ball valve body 100 and the controlling rod 200, passes for controlling rod 200, reaches the effect of sealing.A pair of rim portion 300 is extended in ball valve body 100 tops, and each rim portion 300 has a stepped joining hole 310, for connecting base 10 combinations.One locking plate 700 to be to be same as the mounting type of conventional ball valve, is installed on the controlling rod 200 and interlock with it.

As shown in Figures 1 to 3, the utility model provides a connecting seat 10, it has a central axis hole 20 and passes for controlling rod 200, ear 30 is extended in connecting base 10 both sides, each 30 central authorities of ear is equipped with the joining hole 310 of a through hole 40 corresponding to rim portion 300, and confession one screw rod 400 passes and connecting base 10 is incorporated on the rim portion 300.This screw rod 400 can be a hexagonal screw rod, and through hole 40 wall also is corresponding hexagonal configuration within the hexagonal screw head in holding.The both sides of each ear 30 form alar part 50, and alar part 50 has a through hole 51, and except that the circular hole 710 that can cooperate locking plate 700 is locked, the combination of also can power moving or pneumatic actuator 500 below will be described in detail again.Centre axis hole 20 and the through hole 40 of ear 30, the joining hole 310 of rim portion 300 and all stepped hole of axis hole 110 of ball valve body 100 among the connecting base 10, and centre axis hole 20 all extends extension part 41,21 downwards among the through hole 40 of ear 30 and the connecting base 10, extension part 41,21 also embeds respectively in joining hole 310 and the axis hole 110, wherein, extension part 12 and pressing is surrounded on the pad 800 around the Control Shaft 200, makes ball valve obtain good sealing effect.

When desiring, as shown in Figure 1, be incorporated on the controlling rod 200 with lever 600 with manually-operable ball valve 100; But when desiring to be transformed into automatic operation,, lever 600 is removed, directly electrodynamic type or pneumatic actuator 500 are incorporated on the Control Shaft 200 then, and utilize the alar part 50 set through holes 51 of aforementioned connecting base 10 to supply actuator 500 combinations as long as shown in Figure 2.It should be noted that the design attitude of through hole 51, is to meet ISO(International OrganizationforStandardization) No. 5211 specification, so that the installation of actuator.Therefore, when ball valve was operated automatically from the manually-operable conversion, it is very simple and easy that it changes operation, and vice versa.Simultaneously, because when changing operation, connecting base 10 need not pulled down, so the sealing of 10 pairs of ball valve bodies 100 of connecting base is not damaged, thus need not stop or blinding off a line in changing, more because of changing operation simple, need not increase any member, so with low cost, the volume of combination back reduces significantly.

In addition, ear's 30 set through holes 40 of connecting base 10 can be stepped hole, and as shown in Figure 3, therefore, when screw rod 400 penetrated through hole 40, the head end of screw rod 400 was imbedded in the through hole 40, except the space that minimizing screw rod 400 takies, more can not hinder assembling work.After the long-time use, as if producing slight the leakage from pad 800, the locking of only nut 410 need being gone again gets final product, and needn't pull down actuator, and its operation is very convenient.
