Description
Technical field
This utility model belongs to high-pressure pump technical field, especially relates to a kind of high-pressure plunger pump check valve。
Background technology
Check valve is a kind of valve controlling the fluid flow direction, cleans in pump in plunger type and often uses。Existing check valve is usually and is made up of spring, spool, valve port and sealing ring, it is arranged in corresponding pipeline according to the order of sequence, so installs cumbersome, and be difficult to the relative position ajusting between them when mounted, the sealing making check valve reduces, it is therefore necessary to improved。
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of high-pressure plunger pump check valve, it has the feature of simple in construction, easy for installation, good airproof performance and long service life。
To achieve these goals, this utility model be the technical scheme is that a kind of high-pressure plunger pump check valve, including columnar housing, the left end of described housing is provided with cover, the inner side of described cover is provided with spring, the right-hand member of described spring is provided with the spool of cone, the taper seat of described spool is provided with rubber layer, the inner side of described housing be provided with spool with the use of valve port, the right-hand member of described housing is water inlet, the end of described water inlet is provided with sealing ring, and the housing on the left of described valve port is provided with several outlets。
Being provided with toroidal cavity on the housing of described water inlet end, described sealing ring is arranged in groove。
The lateral surface of described cover is provided with locating convex block。
After adopting said structure, this utility model is compared to the prior art advantageously: simple in construction of the present utility model, spring, spool, valve port, sealing ring and locating convex block are arranged in housing or on housing or on cover, form a constitutionally stable check valve, more convenient to install and long service life, the taper seat of spool is provided with rubber layer so that the good airproof performance of check valve。
Accompanying drawing explanation
Fig. 1 is this utility model and the sectional view of connected pipeline。
Fig. 2 is structural representation of the present utility model。
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, below in conjunction with drawings and Examples, this utility model is further illustrated。
Embodiment, see shown in Fig. 1 to Fig. 2: a kind of high-pressure plunger pump check valve, including columnar housing 1, the left end of described housing 1 is provided with cover 2, the lateral surface of described cover 2 is provided with locating convex block 9, the inner side of described cover 2 is provided with spring 3, the right-hand member of described spring 3 is provided with the spool 4 of cone, the taper seat of described spool 4 is provided with rubber layer, the inner side of described housing 1 be provided with spool 4 with the use of valve port 5, the right-hand member of described housing 1 is water inlet 6, the end of described water inlet 6 is provided with sealing ring 7, housing 1 on the left of described valve port 5 is provided with several outlets 8。
In order to make sealing ring 7 can the stable end being arranged on water inlet 6, the housing 1 of described water inlet 6 end is provided with toroidal cavity, described sealing ring 7 is arranged in groove。
When this utility model uses, as long as being placed in corresponding pipeline (10), and cover with matched water shutoff cap (11)。Locating convex block (9) coordinates with water shutoff cap (11), makes this utility model install not only quick but also accurate。
