For solving the technical problem, the utility model discloses the technical scheme who adopts is:

The utility model provides a valve gap locking device, its characterized in that, including being used for the cover to establish on the valve gap and with first connecting handle and the second connecting handle of the mutual adaptation of valve gap, the second connecting handle is provided with two connectors that are used for with the mutual adaptation of valve gap, the one end and the valve gap interconnect of first connecting handle, the other end of first connecting handle is provided with the spout, be provided with in the spout and can be at gliding slider in the spout, be connected with the nut on the slider, the one end of second connecting handle is through two connectors and the mutual adaptation of valve gap, the other end of second connecting handle has the lead screw with the mutual adaptation of nut through muffjoint connection, the lead screw cover is equipped with and is used for driving the lead screw and carries.

The first connecting handle is provided with a locking screw rod used for locking the sliding block.

A clamping groove is formed in the end, used for being connected with the valve cover, of the first connecting handle, and a pressing block matched with the supporting seat in the valve cover is sleeved in the clamping groove.

And the two connectors of the second connecting handle are connected with the two adjacent valve covers.

The two connectors of the second connecting handle are arranged symmetrically.

Compared with the prior art, the utility model discloses following beneficial effect has:

The utility model discloses a valve gap locking device is in the use, at first establishes first connecting handle cover on the valve gap that needs locking, then does not have not become flexible valve gap interconnect with two through two connectors of second connecting handle, adjusts the position of slider and spout and locks, then drives the lead screw through torque wrench and rotates, drives first connecting handle through mutually supporting of lead screw and nut and rotates to locking not hard up the valve gap. Compare in the current mode that adopts and strike, the utility model discloses the locking of valve gap not only can be realized as supporting to make full use of slush pump self's structure to the sealing washer of valve gap can not be harmd simultaneously to the dismantlement of the follow-up valve gap of also being convenient for has improved the efficiency of valve gap locking and dismantlement greatly.

The utility model has the characteristics of simple structure, easily preparation, the specially adapted field oil development operation.

The utility model discloses because second connection handle and two valve gap connections, consequently the second connection handle can not rotate in the use to the assurance can not lead to the fact the influence to the valve gap of normal use, improved the utility model discloses a practicality.

The utility model discloses not only can be applicable to the locking of valve gap, can also be used for the dismantlement of valve gap, have the characteristics that the practicality is strong.

Detailed Description

The present invention will be further described with reference to the following examples, which are only some, but not all, of the examples of the present invention. Based on the embodiments in the present invention, other embodiments used by a person skilled in the art without creative labor all belong to the protection scope of the present invention.

With reference to the drawings, the valve cover locking device of the present invention comprises a first connecting handle 4 and a second connecting handle 5, which are used to be sleeved on the valve cover 2 and mutually fit with the valve cover 2, wherein the valve cover 2 is installed on the slurry pump 1, and the slurry pump 1 is provided with a plurality of valve covers 2, which can be understood and appreciated by those skilled in the art, and will not be described herein again, the second connecting handle 5 is provided with two connectors for mutually fitting with the valve cover, in the specific implementation process, the second connecting handle 5 can be provided with three connectors mutually fit with the valve covers, the main function of the second connecting handle 5 is to function as a fixed supporting point, since the slurry pump is used in the field, and in addition to the structure of the slurry pump itself, it is very difficult to find a fixed supporting point, the present invention makes full use of the valve cover as a fixed supporting point, and at least two valve covers jointly serve as a fixed supporting point, the second connection portion 5 cannot rotate, so that normal use of the valve cover which is not loosened is guaranteed, and no influence is caused.
