Alternatively or preferably, the number of the liquid inlet pipes is two, and the liquid inlet pipes are symmetrically arranged along the radial direction of the joint body.

Optionally or preferably, the distance between the connection part of the two liquid inlet pipes and the connector body and the end part of the connector body and the distance between the two liquid inlet pipes are 2:1.

Optionally or preferably, the liquid inlet pipe is connected with the side wall of the connector body in an inclined way, and forms an included angle with the side wall of the connector body.

The technical effect of adopting the technical scheme is as follows: through two feed liquor pipes that the slope set up for the liquid flow that gets into the joint body can play the cleaning action to the bigger scope part of joint body inner wall and pressure transmitter diaphragm, improves clean efficiency.

Alternatively or preferably, the included angle is 30 ° -45 °.

Alternatively or preferably, the drain pipe is connected to the middle part of the joint body.

Based on the technical scheme, the embodiment of the utility model at least has the following technical effects:

according to the middle joint for cleaning the pressure transmitter diaphragm, liquid is introduced into the two liquid inlet pipes arranged on the joint body for lavage, the inclined liquid inlet pipes enable the pressure of crystals acting on the pressure transmitter diaphragm to be increased, so that crystals attached to the pressure transmitter diaphragm are easier to fall off, and then flow out through the liquid discharge pipe, the cleaning work of the pressure transmitter diaphragm is completed, the pressure transmitter diaphragm is not required to be detached during cleaning, and the cleaning efficiency of the pressure transmitter diaphragm is improved.
