Abstract
The utility model provides a packing gland, which is applicable to a reciprocating-type plunger pump. The packing gland consists of a packing pressure plate and a sleeve, which are connected with each other through threads; and a spigot is arranged on the outer surface of the sleeve pipe. The utility model has the advantages of simple structure and convenient operation, effectively shortens the replacement time of the frequently-used wearing part (packing) in the plunger pump, and improves the operation efficiency of the oil field. Moreover, the packing gland adopting the structure has the advantages that the no thread processing is needed on the pump head body, thereby simplifying the processing technology.
Description
Technical field
The utility model relates to a kind of packing (packing) gland that is applicable in the reciprocating plunger pump.
Background technique
In reciprocating plunger pump, plunger needs the packing of high pressure sealing, conventional packing gland is generally box structure, packing is contained in the packing box locks, this gland is not easy dismounting, thereby maintain and replace difficulty very, greatly reduce the operating efficiency in oil field, in addition, use the packing gland of box structure also to require machining screw on pump head body, also increased the complexity of processing technology.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of packing gland is provided, and it is applicable to reciprocating plunger pump, and its structural design is simple, removes and installs conveniently.
The purpose of this utility model realizes by following technical measures: a kind of packing gland, comprise packing platen and sleeve pipe, and described packing platen and sleeve pipe are tubular structure, and the two connects threadably, and bushing outer surface is provided with the seam of projection.
In technique scheme, described seam has been provided with the pin of the effect of being connected and fixed.
In technique scheme, described packing platen circumferencial direction is provided with groove.
The utility model is simple in structure, and is easy to operate, effectively shortened the replacing time of easily damaged parts packing commonly used in the plunger pump, improve oil field operation efficient, in addition, used the packing gland of this structure, need be on pump head body machining screw, thereby the processing technology of having simplified.
Description of drawings
Fig. 1 is the overall structure schematic representation of a kind of packing gland of the utility model.
Fig. 2 is the left view of packing platen in the utility model.
Fig. 3 is the user mode figure of a kind of packing platen of the utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of packing gland comprises packing platen 1 and sleeve pipe 2, and described packing platen 1 and sleeve pipe 2 are tubular structure, and the two connects threadably, can regulate the total length of packing gland along with the difference that is screwed into the degree of depth.
Sleeve pipe 2 outer surfaces are provided with the seam 3 of projection.Also be provided with the pin 4 of the effect of being connected and fixed on the seam 3.
As shown in Figure 2, described packing platen 1 circumferencial direction is provided with groove 5, can insert square steeel tube with rotation packing platen 1.
As shown in Figure 3, when using a kind of packing gland of the utility model, at first turn packing platen 1 and sleeve pipe 2 and make it insert degree of depth increase, total length shortens, thereby packing gland integral body can be put into the part that pump head body 6 hollows out from the side, insert pin 4 fixed sleevings 2 then, oppositely twist packing platen 1, the total length elongation of packing gland, sleeve pipe 2 right-hand member seams 3 withstand on the pump head body 6, packing platen 1 left side withstands on the packing 7, to reach the purpose that compresses packing 7.
Its packing gland also can be controlled by the total length of regulating packing gland for the dynamics that compresses of packing 7.
Only whole operation need be reversed when needing the dismounting packing gland and get final product.
Claims (3)
